2. Main uses, performance and characteristics of the machine
This machine is suitable for cutting ordinary steel plates with a thickness of 0.6-6 mm and a width of 2500, 3200, and 4000 mm. The strength of the sheet to be sheared is based on 450N/mm2. If sheets of other strengths need to be sheared, the thickness of the sheet to be sheared should be adjusted accordingly.
This machine adopts steel plate welded body and slider. The fuselage and slider undergo vibration aging treatment to remove welding and machining stress to ensure the accuracy and accuracy of the machine tool are maintained. The shearing of the slider is driven by the hydraulic cylinder and the nitrogen cylinder returns, which can effectively realize the overload protection of the machine tool; the machine tool works stably, has a small size, light weight and good rigidity.
Adjusting the cutting edge gap is quick and convenient. The machine is equipped with front and rear stoppers, and the back stopper adopts mechanical transmission. The rotating display shows the value and can be manually fine-tuned. The adjustment is convenient and reliable. The front stopper uses a ruler to count and the stopper is positioned. In addition, the stroke of the upper tool rest can be adjusted arbitrarily to improve the efficiency of cutting narrow sheets. The machine is also equipped with a guardrail to ensure safe operation.
3. Machine hydraulic transmission system
The hydraulic system of the machine (see Figure 1) mainly consists of 10MCY141B axial piston pump 2, electromagnetic relief valve 3, pressure material 6, nitrogen return cylinder 7, main oil cylinder 8 and collar air reservoir 9. The entire system More reasonable.
The pressure oil required by the system is supplied by the 25MCY-1B axial piston pump 2. The maximum working pressure of the system is 20MPa. The return stroke of the upper tool rest is completed by a nitrogen cylinder, and the pressure of the nitrogen cylinder is about 5MPa.
Working principle of hydraulic system (see Figure 1)
The upper tool rest shears downward: When the electromagnet YV1 of the
electromagnetic relief valve 3 is electrically actuated, the oil output by the plunger pump 2 passes through the electromagnetic relief valve 3 and enters the pressure cylinder and the upper chamber of the main oil cylinder at the same time. When the piston of the pressing oil cylinder presses down to the sheet after overcoming the tension of the tension spring, the oil pressure begins to rise. When the oil pressure rises to overcome the nitrogen pressure of the return cylinder 7, the upper tool rest moves downward for shearing, and this process continues That is to say, the program action between the pressing cylinder 6 and the upper tool rest is realized.
Upper tool rest upward return stroke: When the upper tool rest moves down to the bottom dead center, the electromagnet YV1 of the electromagnetic relief valve 3 loses power under the action of the travel switch, and the upper tool rest begins its upward return journey under the action of the return nitrogen cylinder. At this time, the oil in the upper chamber of the main cylinder flows back to the fuel tank through the electromagnetic relief valve. At the same time, the piston of the pressure cylinder also returns upward under the action of the tension spring. The oil in the pressure cylinder also returns to the tank through the electromagnetic relief valve 3. When the upper tool rest returns to the starting point, the entire shearing process ends.

4. Machine structure
1. Rack:
The frame structure is welded by steel plates and has good rigidity. The two cylinders are fixed on the left and right columns. There is an auxiliary tool rest on the workbench to facilitate micro-adjustment of the lower tool rest to ensure that the gap between the upper and lower blades on the machine tool is consistent. There is also a feeding roller ball installed on the work surface, which is easy to operate.
2. Upper tool rest: It is a steel plate welded structure with good rigidity. It uses the eccentric sleeve (9) as the fulcrum to swing back and forth to complete shearing driven by the left and right oil cylinders and the accumulator return cylinder. (Figure II)
The blade vertical supporting surface of the upper tool rest forms an arc-shaped backing plate to ensure the consistency of the gap between the upper and lower blades during the shearing process.
3. Pressing device: It consists of several pressing cylinders installed on the support plate in front of the frame. After the pressing cylinder is filled with oil, the pressing head presses against the tension of the tension spring (18) to compress the sheet. After shearing is completed, it is reset by the tension of the tension spring.
The size of the pressing force increases with the thickness of the sheared plate.
4. Front and rear stoppers:
Front stopper: Place it on the work surface and use a ruler to indicate the value to adjust the movable stopper to achieve the required stopper value. It is more convenient to use the front stopper when cutting thin steel plates.
The back gauge (see Figure 5) is installed on the upper tool rest and swings up and down with the upper tool rest. The adjustment of the back gauge is driven by a 0.55KW motor, which is driven by a screw rod after being reduced by gears. Press the adjustment button "+ ” (or “ - ” ), the baffle plate can be adjusted forward (or backward). When the motorized adjustment cannot reach the required adjustment value, the manual adjustment wheel (56) can be rotated for manual fine-tuning to ensure The required adjustment value, so the adjustment of the backgauge is convenient and reliable.
The adjustment range of the backgauge is 20~700mm. When the length of the sheet to be cut is greater than the maximum backgauge distance, the baffle plate (43) can be opened to the final position and passed through the slope on the bracket (47) Lift the baffle (43) to cut the sheet of any length.
5. Machine electrical system
This machine uses 50HZ, 380V three-phase power supply. The machine's motor uses single-phase 380V, and the alignment light uses single-phase 220V. The control transformer adopts two-phase 380V. The output 220V of the control transformer is used for the control circuit and alignment lights, of which 27V is supplied to the electromagnetic reversing valve. 6V supply indicator light.

8. Machine adjustment and operation
1. Adjustment of cutting edge clearance:
Whether the blade gap adjustment is appropriate is an important factor that affects the shearing quality and extends the blade life. It is recommended to select the gap value according to the table below.
When adjusting the gap (see Figure 2), loosen the locking screw (4), then turn the handle to the required scale value, and then tighten the screw (4).
The ball valve (on the right side of the machine tool, outside the oil cylinder) is used to measure the uniformity of the gap between the upper and lower blade ports. Specific method: In a single stroke, when the upper tool rest reaches the bottom dead center, quickly turn the ball valve to close the oil circuit to make the upper tool rest
stop at the bottom dead center, and then continue to open and close the ball valve slightly to make the upper tool rest move in the full stroke. As it rises step by step, the uniformity of the cutting edge gap can be measured step by step.
Knife edge gap adjustment method:
1. Rotate the transfer switch to the single position, step on the foot switch, completely overlap the knife edge and quickly close the ball valve (the ball valve is on the other side of the electrical box).
2. Turn off the power
3. Open the ball valve slightly and let the upper knife rise slowly. Close the ball valve every 100mm and check that the knife edge gap measurement part is at the 20mm position of the knife edge coincidence point. But first, adjust the scale to the 0.05 position and lock it.
4. See the figure for the adjustment method:
After aligning the position of the blade, loosen the nut and measure the clearance. The positive rotation clearance of the ejector becomes smaller and the clearance of the rod becomes larger. In the optimal state of the gap, a feeler gauge of 0.03mm can be easily inserted, but a feeler gauge of 0.05mm cannot be inserted. After the completion of the arrangement of the rod and The ejector pin presses against each other and the ejector pin and the movable tool holder press against each other and the locking nut is tightened.
5. Disassemble the pressure plate and check whether the internal hexagonal rod is tightened.
6. After cutting for a period of time, recheck the uniformity of the knife edge gap.
2. Preparation before operation:
(1) Clean the dirt on the surface of each component, and note that the engraved line on the ball valve should point to the open position.
(2) Inject grease into each lubricating part.
(3) Add HL46 hydraulic oil to the tank.
Ground the machine, turn on the power supply, and check the coordination of the actions of each electrical appliance.
3. Operation:
(1) Start the machine and run it dry for several cycles. After ensuring that there are no abnormalities, try cutting sheets of different thicknesses (from thin to thick).
(2) During the shearing process, open the pressure gauge switch and observe the oil line pressure value. If it is abnormal, adjust the relief valve to make it meet the requirements.
(3) During operation, if any abnormal noise or fuel tank overheating is found, stop the vehicle immediately for inspection. The maximum temperature of the fuel tank is <60℃.
9. Machine safety technology and maintenance
1. The operator must be familiar with the structure and performance of this machine. This machine is operated by multiple people at the same time, so a dedicated person must be responsible for directing production.
2. Do not put your hands between the upper and lower blades to avoid accidents.
3. Do not place all miscellaneous tools on the workbench to avoid accidents caused by rolling into the knife edge.
4. The sharpness of the blade should be checked regularly. If the blade is found to be blunt, it should be polished or replaced in time. To polish the blade, you only need to polish the thickness of the blade.
5. All parts of the machine should be checked regularly, the machine and surrounding areas should be kept clean, and the wires should be well insulated.
6. The mesh oil filter installed on the oil suction port of the oil pump should be checked and cleaned regularly to ensure that the oil filter maintains the proper oil flow. If the oil filter is blocked, the oil flow will be reduced and the oil pump will be sucked out, affecting the performance of the oil pump. life.
7. The nitrogen cylinder must not be filled with oxygen, compressed air or other flammable gases. When filling with nitrogen, it should be done slowly.
8. Fill the nitrogen cylinder with nitrogen using a filling tool. The filling pressure is 8MPa.
9. The nitrogen must be drained before removing the nitrogen cylinder.
