6. Side pressure countermeasures for punches

It is the best ideal state for the punch to bear equal load on the left and right (that is, the side pressure is zero) during stamping. When the punch is subjected to lateral pressure, the upper die and the lower die will be offset in the transverse direction, resulting in a part of the die gap. It becomes larger or smaller (uneven gap) and cannot be processed with good precision. The countermeasures for the side pressure of the punch include the following methods:

(A). Change the processing direction,

(B). Single-sided processing (punching, bending, drawing, etc.) products should be arranged in two rows,

(C). Punching The head or die is equipped with a side pressure stopper, and the side of the cutting blade is provided with a guiding part (especially for cutting and breaking processing).

7. Design of back pressure plate

The main parts (punch, blanking plate, die) during the stamping process will be subjected to surface pressure. When the punching pressure is higher than the surface pressure, a back pressure plate (especially the back of the punch and die sleeve) should be used. Back pressure plate There are two forms of use: partial use and full use.

Mold design software

Modern industry is developing very fast, basically using computers for design and processing, and its accuracy can be guaranteed within 0.002~0.01. Engaging in mold design work has a boundless vast world. If you can use computer-aided design, your opponent, invisibly, lags behind you. Commonly used mold design software includes AUTOCAD Pro/E UG SW CImatron, mishiong and so on.
