Forming a shallow concave central hole on the surface of the workpiece is a stamping process, and the backing material has no corresponding protrusion.

Jingchong

It is a smooth blanking. He used a precision die with a toothed blanking plate to smooth the whole section of stamping parts.

modulus of continuity

It is a stamping die with two or more stations, and the material is fed step by step with the stroke of the press, so that the stamping parts are gradually formed.

Single-process die

It is a stamping die, which only completes one process in one stroke of the press.

Combined punching die

It is a universal and adjustable set of stamping dies that gradually form various stamping parts according to geometric characteristics (straight line, angle, arc and hole). Generally, the outline of plane stamping parts needs several pairs of combined dies to be punched several times.

decorate

It is a stamping process, in which one side of the workpiece is pressed by a punch, forcing the material to flow into the opposite pit to form a bulge.

embossing

It is a stamping process that parts of materials are pressed out to form shallow concave patterns, patterns, characters or symbols on the surface of the workpiece. The back of the embossed surface has no protrusions corresponding to the dents.

form

It is the general name of stamping process that changes the shape and size of working parts through material flow rather than material separation.

Smooth blanking

It is a stamping process that directly obtains the whole or basically all smooth sections without renovation. Torsional bending is a stamping process in which one part of a flat or partially flat workpiece is twisted at an angle with respect to another part.

take away

It is a stamping process, which uses a stamping die to separate some materials or workpieces from other materials, workpieces or wastes. Blanking is the general name of separation processes such as cutting, blanking, punching, punching, slotting, cutting, chiseling, trimming, tongue cutting, cutting and repairing.

cut

This is a stamping process, and the material is partially separated along the outline of the opening, but not completely separated. The material to be cut and separated is in or substantially in a plane before separation.

side cut

It is a stamping process to trim the edge of a workpiece with a stamping die to make it have a certain diameter, height or shape.

Tongue cutting

This is a stamping process, and the material is partially separated along the open contour, rather than completely separated. The partially separated material has a certain position required by the workpiece and is no longer on the plane before separation.

cut off

It is a stamping process, in which materials are separated along an open contour, and the separated materials become workpieces or process parts.

rotate

It is a stamping process, which expands the opening of hollow parts or tubular parts outward.

perforate

This is a stamping process, which separates excess material from the material or workpiece along a closed contour to obtain the required hole in the material or workpiece.

Chongque

It is a stamping process, which separates the redundant material from the material or workpiece along the opening contour, and the opening contour forms a gap, the depth of which does not exceed the width.

Cao Chong

Excess material is separated from the material or workpiece along the open contour. A stamping process in which the outline of the opening is in the shape of a groove, and its depth exceeds its width.

Edge curl

It is a stamping process to roll the edge of the workpiece into a nearly closed circle. The axis of a curled circle is linear.
