Understand the common technical terms of metal stamping die.

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

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

modulus of continuity

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

Single-process die

This is a kind of 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 die that gradually forms 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 stamped several times.

decorate

It is a stamping process, which uses a punch to squeeze one side of the workpiece and force the material to flow into the opposite pit to form a protrusion.

embossing

It is a stamping process, in which materials are partially extruded, and shallow concave patterns, patterns, characters or symbols are formed on the surface of the workpiece. The back of the embossed surface has no protrusions corresponding to the pits.

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

This is a stamping process, which can directly obtain the whole or basically all smooth cross section without renovation. Torsional bending is a stamping process in which one part of a flat or partially flat workpiece is twisted at an angle relative 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, stamping, slotting, cutting, chiseling, trimming, tongue cutting, cutting and repairing.

cut

This is a stamping process, which can partially separate the material along the open contour, but not completely. The material to be cut and separated is in or substantially in the plane before separation.

side cut

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

Tongue cutting

This is a stamping process, which can partially separate the material along the open contour, but not completely. The partially separated material has a specific 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.

turn

It is a stamping process that 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 excess material from the material or workpiece along the open contour, and the open 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 contour of the opening. 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

This is a stamping process, which rolls the edge of the workpiece into a nearly closed circle. The axis of a curled circle is linear.
