The mechanical punch press is the kind of machine that takes advantage of high pressure to deform the workpiece. Before the use of the mechanical punch press, these operations were all done by hand - inefficient and laborious. The design principle of mechanical punch press machine is to convert circular motion into linear motion: the flywheel is driven by the main motor, and the gear, crankshaft (or eccentric gear) and connecting rod are driven by the clutch to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is circular.   The mechanical punch press for sale presses the material to plastically deform to obtain the required shape and accuracy.  Therefore, it is necessary to use dies (the upper die and the lower die), place the material between the dies, and the mechanical punch press for sale applies pressure to deform it. With the emergence of mechanical punch press, metal stamping becomes easier, more accurate and more efficient. Generally, mechanical punch press is used for sheet metal stamping.
