Common technical terms for metal stamping dies

What are the technical terms of stamping die?
1 blanking
It is a kind of stamping process that separates part of material or workpiece from other part of material, workpiece or waste by means of punching die. Punching is the general name of the separation processes of cutting, blanking, punching, punching, slotting, cutting, chipping, trimming, tongue cutting, cutting and dressing.
2 incision
It is a stamping process in which the material is partially rather than completely separated along the open contour. The material that is cut and separated is located on or basically on the plane before separation.
3 trimming
It is a kind of stamping process that uses the edge of the part in the process of trimming to make it have a certain diameter, a certain height or a certain shape.
4 cut tongue
It is a kind of stamping process that partially separates the material along the open contour rather than completely separates it. The partially separated material has a certain position required by the workpiece and is no longer located on the plane before the separation.
5 cut off
It is a stamping process that separates the material along the open contour, and the separated material becomes a workpiece or a working piece.
6 flaring
It is a kind of stamping process that expands the hollow or tubular parts outward in the open place.
7 punching
It is a stamping process that separates redundant materials from materials or working parts along the closed contour, and obtains the required holes in materials or working parts.
8 deficiency
It is a stamping process that separates redundant materials from materials or working parts along the open contour, and opens the contour to form a gap whose depth does not exceed the width.
9 flush tank
It is a stamping process that separates the redundant material from the material or work piece along the open contour. The open contour is grooved and its depth exceeds its width.
10 punching center hole
It is a kind of stamping process in which shallow concave central hole is formed on the surface of the working piece, and the back material has no corresponding bulge
11 fine blanking
It is a kind of smooth blanking. It uses a fine blanking die with a toothed blanking plate to make the whole section of the punch piece smooth.
12 progressive die
It is a die with two or more working positions. The material is fed into the die one by one with the stroke of the press, so that the stamping parts can be formed step by step.
13 single process Die
It is a die that only one working procedure is completed in one stroke of press.
14 combined die
It is a general adjustable complete set of punching dies for all kinds of punches according to geometric elements (straight line, angle, arc, hole). The outline of planar stamping parts usually needs several sets of combined stamping dies to be punched in stages.
15 pressure bump
It is a stamping process in which the punch is used to squeeze the material into the opposite pit to form a bulge.
16 embossing
It is a kind of stamping process in which shallow concave patterns, patterns, words or symbols are formed on the surface of workpiece by local forced extrusion. The back of the embossed surface does not correspond to a shallow bump.
17 forming
It is a general term for stamping process that depends on material flow and does not depend on material separation to change the shape and size of working parts.
18 smooth blanking
It is a blanking process that can directly obtain all or almost all of the whole section without renovation. Torsional bending is a stamping process in which one part of a flat or partial flat part is twisted at a certain angle relative to the other part.
19 roll edge
It is a stamping process that rolls the edge of the working piece into a closed circle. The axis of the curling circle is linear.
20 coiling edge
It is a stamping process to roll the upper edge of the hollow part into a closed circle.
21 drawing
It is a kind of stamping process to change the straight blank or workpiece into a curved surface. The curved surface is mainly formed by the extension of the material at the bottom of the punch.
22 stretch bending
It is a stamping process to realize bending deformation under the combined action of tension and bending moment, so that the whole bending cross-section is subjected to deep drawing stress.
23 bulging
It is a stamping process that expands hollow or tubular parts along the radial direction.
24 section cutting
It is a stamping process that divides the forming process into several parts.
25 school level
It is a stamping process to improve the flatness of parts.
26 undulating forming
It is a stamping process that relies on the extension of materials to form local depressions or bulges in the working parts. The change of material thickness in undulating forming is formed naturally in the process of deformation, not the requirement specified by design.
27 bending
It is a kind of stamping process that makes use of pressure to produce plastic deformation of material and then bend it into a shape with certain curvature and angle.
28 chisel
Cutting is a blanking or punching process using a cutting die with a sharp edge. Cutting does not have a punching die, but only a flat plate underlying the material. Most of the punched material is non-metal.
29 Deep Hole Punching

It is the punching process when the diameter of the hole is equal to or less than the thickness of the punched material.
30 blanking
A stamping process in which materials are separated along closed contours. The separated materials become workpieces or process parts, most of which are planar.
31 necking
It is a kind of stamping process to compress hollow or tubular openings to reduce them.
32 plastic surgery
It is a stamping process that relies on material flow and changes the shape and size of workpiece in a small amount to ensure the accuracy of workpiece.
33 refurbishment
It is a stamping process to cut a small amount of material along the outline or inner outline, so as to reduce the surface roughness and improve the verticality. In general, the renovation process also improves the dimensional accuracy at the same time.
34 turning hole
It is a stamping process to turn the material into a short side or flange along the shape curve or around the inner hole.
35 deep drawing
It is a stamping process to change the straight wool or working parts into hollow parts, or to further change the shape and size of hollow parts. Space-time core in deep drawing mainly depends on the bottom of punch.
