The machines,are used for punching shear the cold crimped engine bed with the thickness of 1.2value="2.5" hasspace="False" negative="True" numbertype="1" tcsc="0">-2.5mm,the width of value="2000" hasspace="False" negative="False" numbertype="1" tcsc="0">2000mm,material sterngth of 450N/mm2,the specifications of punching shear are surveyed by the bit of TB5-20 mesh grid plate:if the TB,TL are changed,the punching shear knife is also changed;TB,TL are increased,the punching shear strength is reduced,TB,Tlare reduced,the punching shear strength is increased.in order not to danage components for the excess load.the nominal tonnage is 63T.if TB,Tlare reduced,the punching shear strength surpasses the nominal tonnage,you can reduce the material thickness and width.

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

  Feed machines 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
