Hydraulic Punching Machine

A hydraulic punching machine is an example of a machine that works via liquid pressure. The machine consists of a piston inside a cylinder, with the piston connected to a ram. The ram pushes against a workpiece, forming a hole in it. The ram is actuated by hydraulic pressure, which is generated by a pump.A punching machine is a machine tool for punching and embossing flat sheet-materials to produce form-features needed as mechanical element and/or to extend static stability of a sheet section.Punching metal works in the exact same way: the sheet lies between the punch and the die. The punch moves down and dips into the die. The edges of the punch and die move past each other in parallel, cutting the sheet. This is why punching belongs to the shear cutting process group.
