Prevention of gnawing die in stamping process

In the processing engineering, we will encounter a variety of problems, which must be solved as soon as possible, otherwise it will affect our work, so it is not good, some problems will also affect the quality of processing, not hit the mold damage and so on, so we will understand how to prevent the phenomenon of gnawing die in the stamping process?

(1) In terms of design and equipment, if the punch is not fixed properly, such as fixing the punch by chiseling, the punch may become loose. If the low melting point alloy is used for pouring, the punch may become loose. If the blanking force is large and the root of punch is not hardened and the punch is subjected to excessive lateral force, the punch may become loose.

(2) Mold manufacturing

1. Vertical or no punch mounting.
2. The assembly of upper and lower templates, fixed plates, convex and concave dies are not parallel to each other.
3. The blanking clearance is not uniform.
4. The punch fixation did not meet the design requirements.

(3) Mold use

1. Repeated blanking or overlapping blanking, that is, one blank is punched twice or several blanks are stacked together for blanking.
2. The scraps or blanking parts left on the mould are not cleaned in time.

(4) Mold maintenance

1. The parts of the die have great wear, such as the guide parts wear, resulting in excessive fit clearance and not timely repair.
2. The mold is loose in maintenance and assembly.

The above points are how to prevent the phenomenon of gnawing die in the process of stamping. When dealing with the problems, we must pay attention to some details to avoid causing greater hidden dangers. Let’s talk about it today.
