What is Metal Shearing and How Does it Work Metal fabrication is one of the most important processes in the manufacturing industry. For the metal to be altered into something useful it needs to be fabricated. The first step towards metal fabrication is the cutting of the metal. There are different methods to cut a metal varying from manual to mechanical processes. One such popular method of cutting metal is shearing. Metal shearing is a process where a sheet of metal is separated by applying great shearing force to it. In this article, we will discuss how the process of metal shearing really works.
The Shearing Machine Basically, the process of shearing produces straight line cuts to separate any given piece of metal sheet. The machine which facilitates the shearing process is called power shear. It can be operated manually by labourers or can use advanced modes like hydraulic, pneumatic, or electric power.
How it works The machine holds the metal sheet in the exact position so that it comes between the blades or with precise measurements. The upper blade or the punch and lower blade (the die) are not placed at the same position. There’s a slight difference or offset between them called the clearance. Normally, the lower blade remains stationary while the upper blade is pushed downwards forcefully. It is set at such an angle that the cut is made from one end to another, instead of at once.
