Stamping die terminology basics

1, curling

Crimping is the process of the edge of the roll into a nearly closed round of a stamping process. The axis of the curl circle is linear.

2, wound edge

Roll edge is the upper edge of the hollow part rolled into a nearly closed circle of a stamping process.

3, drawing

Drawing is a stamping process that converts a straight stock or work piece into a curved shape that relies mainly on the extension of the material at the bottom of the punch.

4, bend

Tensile bending is the combination of tension and bending moment to achieve bending deformation, so that the entire bending cross-section of all tensile stress by a stamping process.

5, bulging

Bulging is a stamping process that expands a hollow or tubular member radially outward. Cutting is cutting the forming process piece into a few stamping process.

6, leveling

Leveling is to improve the local or overall planar flatness of a stamping process. Undulating forming

7, undulating forming is to rely on the extension of the material so that the process of forming a partial depression or convex stamping process. The change in material thickness during undulation is non-intentional, meaning that a small change in thickness is a natural result of the deformation and is not a design requirement.

8, bending
Bending is the use of pressure to make the material plastic deformation, which is bent into a certain curvature, a certain angle of the shape of a stamping process.

9, chisel cut

Chiseling is the use of cutting edge chisel die cutting or punching process. Chisel cut no mold, the pad below the material is only flat, the vast majority of red material is non-metallic.

10, deep hole blanking

Deep hole blanking is the hole diameter equal to or less than the thickness of punched material punching process.

11, blanking

Blanking is a stamping process that separates materials along a closed contour. The separated material becomes a workpiece or a work piece, most of which are plano-shaped.

12, narrow mouth

Necking is the hollow part of the tubular or open parts of the pressure to reduce a stamping process.

13, plastic surgery

Plastic is to rely on material flow, a small amount of change the shape and size of the workpiece, in order to ensure the accuracy of a stamping process.

14, renovation

Renovation is a punching process that cuts a small amount of material along the outline or profile to improve edge finish and verticality. Repair process generally also improve the dimensional accuracy.

15, turn hole

Turn-over is a punching process that turns the material into a side up flange around the bore.

16, flanging

Flanging is a stamping process that turns the material into a side short edge along the profile curve.

17, drawing

Drawing is a stamping process that changes a straight stock or work piece into a hollow piece or further changes the shape and size of the hollow piece. Deep hollowed hollow parts mainly rely on the material located outside the bottom of the punch into the die.

18, continuous drawing

Continuous drawing is a stamping method that gradually forms the desired shape and size on a strip (roll stock) by multiple drawing with one and the same die (continuous drawing die).

19, thinning deep

Thinning is the deepening of the hollow part of the workpiece to further change the shape and size, intended to thin the sidewall of a drawing process.

20, anti-deep

Anti-deep processing is the hollow part of the inner wall valgus a deep drawing process.

21, poor temperature deep drawing

Poor temperature drawing is the use of heat, cooling means, the temperature of the material to be deformed is much higher than the temperature of the deformed part of the material, thereby increasing the degree of deformation of a drawing process.

22, hydraulic drawing

Hydraulic drawing is the use of a liquid contained in a rigid or flexible container instead of a male or female die to form a hollow part of the drawing process.

23, pressure tendons

Bending is a form of ups and downs. When the local ups and downs in the form of tendons, the corresponding undulating forming process is called pressure tendons.
