Punching is a basic stamping process that uses a mold to separate materials. It can be directly made into flat parts or prepared for other stamping processes such as bending, deep drawing, forming, etc., and can also be cut, repaired on the formed stamped parts. Wait. The blanking process accounts for about 50% to 60% of the entire stamping process.

Punching is a basic stamping process that uses a mold to separate materials. It can be directly made into flat parts or prepared for other stamping processes such as bending, deep drawing, forming, etc., and can also be cut, repaired on the formed stamped parts. Wait. The blanking process accounts for about 50% to 60% of the entire stamping process.

First, the basic process

Punching is divided into blanking and punching. The punching method for obtaining a certain shape or blank by punching is blanking; otherwise, the punching is obtained.

Technical design of stamping parts

1. The shape and size of the blanking parts are as simple as possible to minimize waste during layout. The picture shows no waste layout.

2. Avoid sharp corners in the shape and inner hole of the blanking part. There should be a circular link at the link of a straight line or a curve, and the arc radius R1.5t (t is the plate thickness).

3, punching parts should avoid narrow and long cantilever and slot

The depth and width of the convex part of the blanking part are generally not less than 1.5t (t is the thickness of the material), and at the same time avoid narrow interfaces and excessively narrow grooving to enhance the die edge strength.
