#149 Design of Hole Punching Dies (9) Design of the Backing Plate
Category :Shear Forming March15,2013
A force equivalent to the machining force acting on the punch is also generated on its back face.This force is received from the face of the punch holder,etc.
In the case of a punch with a small cross-section,as shown in Fig.1,this force cannot be received sufficiently by the surface of the holder and the punch may dig in to the plate.
In the case of a punch with a small cross-section,as shown in Fig.1,this force cannot be received sufficiently by the surface of the holder and the punch may dig in to the plate.In the case of a punch holder material such as S50C that is used without heat treatment,as a guide,when the average surface pressure on the back face of the punch (the load per unit area when the force is considered to be received by uniformly distributing the machining force over the surface of the punch flange) becomes more than 16Kg/mm2,the punch is likely to dig into the punch holder.
