SIGMA MODEL 2598 T-NUT DRIVE MACHINE

The Sigma 2598 Hopper-fed T-nut Drive Machine locates and inserts t-nuts into wood, plastic or fibreboard workpieces. The t-nuts are loaded into a vibratory feed bowl and are fed automatically into position under a pneumatically operated driver. The operator locates a hole in the workpiece under the driver and depresses a foot pedal to activate the driver and insert the t-nut.

The Model 2598 is suitable for a wide variety of t-nut insertion applications. The rugged design has a number of outstanding features: (1) Powerful steel frame that is built to withstand the punishment of rivetting or flaring applications. The Sigma flaring system provides extreme resistance to push-out by rivetting the t-nut into place.

(2) Flexible design that allows for quick access to components for easy maintenance and fast changeover between different t-nuts.

(3) High performance feed system that keeps up with the fastest operator without jamming.

(4) Lower noise level as a result of the heavy steel frame which absorbs the shock of impact.

(5) Choice of drive system that allows machine to be tailored to virtually any application.

MODEL 2598(U) T-NUT DRIVE MACHINE

SIGMA ULTRAGRIP AND COUNTERBORE T-NUTS

Sigma patented Ultragrip and Counterbore t-nuts have been specifically engineered for trouble-free operation. A patented shoulder design [1] prevents them from shingling in the machine track to eliminate jamming. Superior holding power for the Ultragrip t-nuts is provided by long serrated prongs [2].

The Sigma Counterbore t-nuts have all the same features as Ultragrip, but have an unthreaded portion [3] at the top of the barrel which can be flared open. When configured with special tooling, the barrel is flared open slightly during insertion to create extra holding power in the workpiece [4].

Sigma Ultragrip and Counterbore t-nuts come in a wide variety of inch and metric sizes suitable to virtually all applications. Small base t-nuts for the 2598-S are available in thread sizes from 8-32 to 1/4-20 (4mm to 6mm). Large base t-nuts for the 2598-L are available in thread sizes from 1/4-20 to 3/8-16 (6mm to 10mm).

Consult a Sigma representative to recommend the suitable t-nut size for any application, and also provide you with additional information about the following options for special requirements: (1) Special Finishes. Various special finishes are available that can provide increased rust protection if required. A range of options the equivalent of 50 to 1000 hours of salt spray protection are available.

(2) Torq-Loq T-Nuts. This optional locking feature on the barrel increases resistance to bolt turnout. Small indentations on the outside of the barrel deform the threads on the inside resulting in increased holding power available in varying amounts, depending upon application and desired effect.

MACHINE SET UP

5.1 Overview

To obtain the highest performance and productivity, the Model 2598 T-nut Drive Machine must be properly set up for each application. The following points need to be considered: (1) T-nut Selection. The style, size and height of the t-nuts must be chosen depending on the requirements of the application. A Sigma representative can assist you in selecting the most appropriate t-nut for your application.

(2) Hole Size in Workpiece. Use the hole diameter recommended for the particular t-nut used in the application. Undersized holes may result in chips of workpiece material blocking the thread of the t-nut after insertion. Where the hole is tapered, the minimum hole diameter must be larger than the barrel diameter of the t-nut. Refer to Table in Appendix see page 49.

(3) Guide Pin. The guide pin is the spring loaded pin located at the tip of the drive rod. The guide pin must be chosen to match the t-nut to be used.

(4) Anvil Locating Pin. The anvil locating pin is located in the centre of the anvil. The anvil pin should be chosen to suit the size and type of hole in the workpiece. A different style of pin is required to flare or rivet t-nuts in place.

(5) Feed Track Sensor. The feed track sensor is a proximity sensor that is mounted directly in the feed track. It detects the presence of a tnut in the track to command the feeder cube on/off to keep the track full of tnuts. An led light indicates proper function of the system. Ensure it is flush with the bottom of the track, and always kept clean.

(6) Work Height. The height of the frame can be raised or lowered to suit the operator or to accommodate specific workpieces.

(7) Drive Cylinder Size. Several sizes of drive cylinder are available. Each offers a different range of power. Factors affected by the choice of cylinder include noise, impact shock, and cycling speed.

MODEL 2598(U) T-NUT DRIVE MACHINE

Guide Pin

The Guide Pin [1] is a spring loaded pin located at the lower tip of the drive rod [2]. Its purpose is to keep the t-nut positioned on the guide rod during the downward stroke of the piston.

The diameter of the pin should be slightly less than the inside diameter of the t-nut, and the t-nut should slide easily over the pin without binding.

If the Guide Pin is broken or damaged, if the Spring is broken, or if the incorrect size of pin is being used, the Guide Pin or Spring must be replaced.

Refer to Section 7.1 for instructions on removing the drive rod and changing the Guide Pin or Spring.

REVISED MAY 2018

MODEL 2598(U) T-NUT DRIVE MACHINE

PAGE 11

Anvil Locating Pin

The anvil locating pin [1] is located in the centre of the anvil. Its primary purpose is to accurately locate the hole in the workpiece prior to driving the t-nut. In a rivetting application, the anvil pin also provides the bearing surface on which the t-nut is flared open. A spring retaining pin [2] locks the anvil in the anvil holder. Air supplied to the anvil body [3] prevents build-up of wood chips.

A wide variety of standard anvil pins are available for different applications. In some cases, a custom made pin will be required. A Sigma representative can assist you selecting the appropriate anvil pin for your application. Refer to section 7.2 for instructions on removing the anvil pin.

5.3.1 Standard Anvil Locating Pin (Non Rivetting)

Standard anvil locating pins are used in non-rivetting applications. Select a pin which is slightly smaller than the diameter of the hole into which the t-nut is to be inserted [1]. The tip of the pin should fit easily into the hole without binding. However, if the pin is too small, the workpiece may not be properly located when the t-nut is inserted, and the t-nut can catch the side of the hole, causing a chip to be lodged in the thread of the t-nut.

Holes that have been punched or moulded rather than drilled are often tapered. To locate such holes reliably, a custom made pin may be required. Contact a Sigma representative for a consultation and test pieces if required.

REVISED MAY 2018

PAGE 12

MODEL 2598(U) T-NUT DRIVE MACHINE

5.3.2 Rivet Anvil Locating Pin

The rivet anvil locating pin rivets a counter-bore rivet style t-nut (CR) into the workpiece by flaring open the un-threaded portion of the CR t-nut [1] to significantly increase the resistance to pushout during assembly operations. This flaring action is adjustable to either flush on the surface of the workpiece [2] or inside the hole [3] depending upon the application.

The amount of flaring or rivetting action is adjusted by raising or lowering the rivet anvil pin in the holder. Adjust the height of the pin by releasing the locknut with a wrench [4] and turning the adjustment screw with a hex key [5]. Turning the screw counter-clockwise will raise the pin in the holder and increase the amount of flaring, while turning the screw clockwise will lower the pin and reduce flaring. Always secure the lock-nut tightly after making adjustments.

Note: Do not over flare the CR t-nut or damage to threads is possible. Always periodically check the set-up with a bolt.

Height Adjustment

The height of the 2598 steel frame is adjustable to suit the operator and the application. By adjusting the machine to the appropriate level, operator performance and quality of work will be optimized.

Note: To safely perform this procedure, always use a hoist or forklift as a lifting device.

(1) Carefully loop a sling securely around the upper frame of the machine (2) Remove only the front bolts [1] attaching the frame to the front leg.

(3) Raise the machine to the desired height and replace the bolts to the correct holes.

(4) Then repeat the procedure for the rear bolts.

Note: Ensure all 4 bolts are secure before operating machine.

Drive Cylinder

A number of drive cylinders [1] of different heights are available with the Model 2598 T-nut Insertion Machine. The taller the cylinder, the more power it provides at a given drive pressure.

Consider using a shorter cylinder if an application requires drive pressure below 20 PSI (1.3 bar). If a workpiece consists of soft material, it may be essential to use the shorter cylinder to achieve consistent depth of drive.

Use a taller cylinder if an application requires drive pressure above 90 PSI (6 bar). The taller cylinder will provide the same power at a lower pressure setting, while also reducing the noise level.

When specifying the cylinder, measure the height from above the upper cap [2] to under the lower plate [3].

MACHINE OPERATION

6.1 Start-up

Prior to commencing work with the Model 2598 t-nut drive machine, the operator should follow these steps: (1) Check that the feed bowl is approximately half full of t-nuts.

(2) Switch feed bowl toggle [1] to ON. Bowl will start to feed only if track is not filled with t-nuts up to the feed track sensor. Adjust knob [2] on feed control box to control feed rate of bowl.

(3) Make certain that the feed bowl stops vibrating once the t-nuts have filled the track. If the bowl keeps running it may indicate that the shut-off sensor is not in the correct position, and this could cause t-nuts to jam repeatedly in the feed bowl.

(4) Connect air pressure only when anvil is clear.

(5) Check that the anvil safety is working properly. Connect the air, and hold down foot pedal without locating a workpiece on the anvil. If the machine cycles, then the safety is ineffective, and the machine should not be used until the problem has been corrected. If air escapes continuously from safety valve [3] while the foot pedal is being held down, then the connection hoses to the safety valve have been reversed in error (Sect 7.7.3).

REVISED MAY 2018

MODEL 2598(U) T-NUT DRIVE MACHINE

PAGE 17

6.2 Operation

Slide the workpiece under the safety arm and locate the hole over the anvil pin. The grated area of the safety arm allows visibility to assist the operator in locating the hole.

Once over the hole, the operator must apply a slight downward force to depress the anvil safety. When the anvil safety has been pressed, the operator must press the foot pedal to drive a t-nut into the hole.

Note: Periodically check t-nuts with a bolt after inserting into workpiece.

It is good practice to periodically check the t-nuts after they have been inserted with a bolt.

If it is difficult to start the bolt because of chips of material have become lodged in the thread or some other reason, the setup of the machine should be adjusted to correct the problem. With rivetting or flaring t-nut, it is particularly important to be sure that the threads are not being collapsed by over-rivetting.

REVISED MAY 2018

MODEL 2598(U) T-NUT DRIVE MACHINE

Drive Pressure

The main pressure regulator [1] and gauge [2] provide precise control of the force used to drive the t-nut. To drive the t-nut deeper into the workpiece, increase the drive pressure.

Note: It is recommend to check t-nut insertion periodically both visually & with a bolt to ensure the drive pressure is properly set for the application.

Between the main pressure regulator and the main valve is the return regulator [3]. This regulator controls the air pressure used to return the piston back to the top of the cylinder after the drive stroke. It is not recommended that the pressure of the return regulator exceeds 25psi.

Note: When rivetting t-nuts check the t-nut after insertion with a bolt periodically to ensure that no over-flaring is occurring

Behind the main valve is the smaller return regulator [3]. This regulator controls the air pressure used to return the piston to its raised position after a t-nut has been inserted. The return regulator [3] is factory set and should not be adjusted. If the return pressure is set too high, it will steal power away from the drive stroke (see Section 7.7.4)

Safe Operating Procedures

Caution should be exercised at all times when working with the machine. Safe work practices must be instituted and enforced. Following is a general guide to safe operation of the machine.

(1) Compressed air should be disconnected when machine is not being used.

(2) The machine should not be operated if the safety features have been removed, disabled or are not working.

(3) The anvil safety [1] should be checked daily to ensure that it is functioning correctly (Section 6.1).

(4) Operators should never place their hands between the safety arm [2] and the anvil unless the compressed air is disconnected.

(5) When clearing any jam from the under the drive cylinder, the compressed air must be disconnected.

(6) Prior to performing any maintenance compressed air should be disconnected and power to the feed bowl removed.

(7) Operators should be trained on the proper use of foot-pedals. When a piece is finished or the work flow is interrupted, the operator should completely remove his or her foot from the foot-pedal.

Guide Pin/Drive Rod Spring

The spring loaded guide pin is located inside the drive rod and keeps the t-nut properly aligned with the anvil pin during the drive stroke. If either the guide pin and/or drive rod spring are broken, the machine can misfire and the broken parts must be replaced. Also changing to different size tnuts may require a different guide pin.

To change either the pin or the spring, the recommended procedure as follows; (1)

Disconnect main air supply. Remove the front shield [1], and relocate the safety arm [2].

(2)

Separate drive rod from piston shaft using tools supplied in toolbox. Placing tools on flats provided, keep bottom wrench stationary, and turn upper wrench counterclockwise [3].

(3)

Once the drive rod and piston are separate, the spring [4] can be removed, inspected and replaced if necessary.

(4)

If necessary to replace the guide pin, proceed to remove the front plate using tools supplied in toolbox [5].

Note: Never apply a wrench or a vice to the polished ground finish of the piston rod.

MODEL 2598(U) T-NUT DRIVE MACHINE

Anvil Locating Pin

The anvil locating pin is located in the center of the anvil body [1]. This pin locates the hole in a workpiece to the desired location for the tnut to be driven. A compressed air line enters the anvil pin holder to keep it clear of chips [2]. If the pin is damaged, broken or needs to be changed for a different size of tnut, it can easily be changed. Disconnect the main air supply to ensure safety.

Then remove the screw [3] to allow the anvil pin holder to be removed from the anvil body [4] . Then remove the 2 smaller screws [5] on the cap to remove and replace the pin as required. It is recommended at this point to check and replace the anvil body spring, if necessary.

7.3

Escapement Finger Springs

These flat shaped springs [1] are located on either side of the drive rod and hold the escapement fingers closed which keeps the t-nut located in proper position to be driven into the workpiece.

When the operator cycles the machine, the drive stroke forces the front fingers open slightly to allow the t-nut to pass. If one or more finger springs are broken, damaged or misaligned, misfiring of t-nuts could result. Remove the front safety shield (already removed) to access the screws [2] to replace.

When replacing with new fingers note the springs for the rear fingers are shorter than the fingers for the front fingers.

MODEL 2598(U) T-NUT DRIVE MACHINE

Feed Bowl Adjustment

The Vibratory Feed Bowl advances, sorts, and selects t-nuts and guides them into the track ready for use. The Model 2598 T-nut Drive Machine has been designed to accommodate a variety of t-nuts of different sizes and barrel lengths.

The operation of the feed bowl is controlled by three components: an electromagnet located under the feed bowl, a control box, and a proximity sensor located on the track. Each of these must be set correctly to ensure optimum performance of the feed bowl.

7.6.1 Feed Bowl Magnet

The electromagnet [1] drives the feed bowl. The magnet is turned rapidly on and off, causing the feed bowl to vibrate and advance the t-nuts. The small upper portion of the magnet is mounted to the vibrating bowl, and the more substantial lower portion is attached to the base of the feed unit.

For best performance, the upper and lower portions of the magnet must be separated by a uniform gap [2] of .040 - .060 inch (1 - 1.2 mm). The gap is adjusted by raising or lowering the lower part of the magnet which is mounted on four threaded studs mounted on a adjustable bracket.

7.6.2 Track Proximity Sensor The track proximity sensor [3] commands the feeder cube to start/stop the bowl by sensing the presence of t-nuts in the track. Since it is fixed mounted to the track it should not need adjustment.

Ensure the sensor is flush to the bottom of the track, and periodically clean it to ensure the track is always full of t-nuts.

REVISED MAY 2018

MODEL 2598(U) T-NUT DRIVE MACHINE

PAGE 31

7.6.3 Feed Bowl Control

The feeder cube controls the rate at which the t-nuts are fed into the track. To operate machine effeciently ensure the feeder cube is plugged in to appropriate receptacle, turned to ON [1] position, and the vibratory feed dial [2] is set at a rate high enough to feed t-nuts and keep track full, but not too high that caused them to excessively tumble in the bowl and not orient properly. If switching t-nut sizes, adjust the feed rate as required.

The feeder cube comes with separate instructions from the manufaturer that are included in the Appendix section of this manual. Several switches and adjustment pots are located on a circuit board inside the control box.

The following are recommended settings: (1) 60 Pulse Operation (2) ON DELAY = 3 seconds (3) OFF DELAY = 1/2 - 1 second (4) INPUT SWITCH = N.O. (Normally Open)

Note: Only qualified electrical personel should adjust these factory settings

The Pneumatic Circuit

7.7.1 Overview

All main functions of the 2598 t-nut machine operate on compressed air, except for the feed bowl which is single phase electric.

Compressed air enters the machine via quick disconnect fitting at the manifold [1] and then filtered [2] and regulated [3] to the main valve [4].

When the operator presses the foot pedal [5], air pressure activates the drive cyclinder [6] and the tnut is driven into the workpiece. This action also sends compressed air to the lower track to feed assist the t-nuts [7], as well as to the anvil holder to keep it clear of chips [8]. Compressed air then exits the system by the exhaust muffler [9].

Between the air filter and drive pressure regulator is a small takeoff port [1] that supplies air at full pressure to the control manifold via port [2]. Compressed air exits the control manifold via port [3] and enters the anvil safety valve [4].

When the operator presses the workpiece down on the anvil and triggers the anvil safety valve, this allows compressed air to exit the anvil safety valve [5] and return to the control manifold via port [6]. Compressed air then exits the control manifold via port [7] and enters the foot pedal [8]. When the operator presses the foot pedal down compressed air returns from the pedal [9] to the control manifold via port [10].

The control manifold is also connected to the blower valve [11] which supplies compressed air via line [12] to the anvil holder [13] to keep it clear of chips, and via line [14] to the lower track [15] to assist feeding the t-nuts.

The length of time of the blower valve air blast can be adjusted with the blower needle valve [16].

Compressed air exits the needle valve and enters the main valve pilot via port [17] and then returns to the control manifold via port [18].

7.7.3 The Drive Stroke

When the operator locates a workpiece activating the anvil safety, and then presses the footpedal, compressed air acts on the drive cylinder to insert the t-nut into the workpiece.

Compressed air exits the safety valve via port [5] and enters the control manifold via port [6]. Compressed air then exits the manifold via port [7] to the foot pedal via port [8]. When the foot pedal is pressed down, compressed air exits the foot pedal via port [9] and then returns to the control manifold via port [10]. Compressed air then exits the manifold via port [18] and is then directed to the pilot of the main valve via port [17]. This causes an internal spool to shift which directs the compressed air to the upper port of the drive cylinder [19] at the pressure displayed on the main pressure gauge [20]. Air is exhausted through the bottom port of the cylinder [21] allowing the piston to drive the t-nut into the workpiece.

Note: Adjust main pressure no higher than required to suit the application.

During this drive sequence, compressed air is also directed to the blower valve [11]. Compressed air in the upper line [14] goes to the track to assist the t-nut feed system [15]. Compressed air in the lower line [12] goes to the anvil holder to keep it clear of chips [13].

Note: The amount of air flow for both is factory set but can be adjusted as necessary with knob [16].

7.7.4 The Return Stroke

When the operator releases the footpedal and removes the workpiece, compressed air is exhausted from the system, and the return drive pressure causes the piston to return to the top of the drive cylinder.

When the foot pedal is released, a spring in the pilot of the main valve [17] causes the internal spool to shift back to its original position and compressed air is released from the main valve to the control manifold via port [18] and then to the foot pedal exhaust.

At the same time, compressed air is directed from the main valve to the bottom port of the drive cylinder [21] at pressure displayed on the return pressure gauge[22]. Air is released from the upper port of the drive cylinder [19] and exhausted through the main valve to the muffler. This allows the piston to return back to the top of drive cylinder.

The compressed air pressure for the return stroke is factory set at 25psi. and should not need adjustment. Never exceed 25psi return pressure or damage to cylinder could result.

Note: When removing hoses to service pneumatic components, ensure they are replaced in proper position or unpredictable machine behavior may result.

7.7.5 Troubleshooting Pneumatic Circuit Problems

When faced with a problem in the pneumatic circuit, it is important to follow a systematic procedure for locating the source of the trouble. Never disconnect more than a single hose connection at a time. Instead, test a specific area of the pneumatic circuit by disconnecting a single hose connection at a time, and checking the result. After each test, replace the hose connection, and try another one until the problem is located.

As an example, consider a case where the air was applied, a workpiece is in place releasing the anvil safety, but nothing happened when the foot pedal is depressed. A good place to start is to disconnect the hose connected to the pilot [1] of the main valve [2] which comes from the safety valve by way of hose [3]. Once the hose is disconnected, attempt to cycle the machine. With the foot pedal depressed and a workpiece in position, there should be a strong flow of air through the hose.

If the strong flow of air is present, then the control circuit is working properly and the problem lies somewhere in the drive circuit. If there is no air flow or one that is very weak, the problem lies in the control circuit, perhaps with the safety valve or the foot valve. In either case, reconnect the line, and work forward or backwards through the circuit to locate the problem.
