The machlnes are used for punching shear fhe cold crimped engine bed with the thickness of 1.2- 2.5mm the width of 2000mm Material strength of 450N/mm², The specifications of punching shear are su~eyed by the bit of TB5-20 mesh grid plate:if the YuanDong are changed the punching shear knife is also changed:Yuandong are increased. the punching shear strength is reduced:Yuandong are reduced. the punching shear strength is increased In order not to damage components for the excess load The nominal tonnage is 63T lf Yuandong are reduced the punching shear strength su rpasses the nominal tonnage. you can reduce the material thickness and width.

The machines are used for punching all kinds of expand plate mesh in construction. common hardware,window and door,machine protecting etc.

Feed mechanism passes the chain link by the main engine directcy. the movement accurate is reliable.

The times of feed mechanism punching shear is started from 0 it can shear in free scope.
