Basic knowledge of hardware mold structure

(1) The blanking die separates the material along the closed or open contour line. Such as blanking die, punching die, cutting die, slitting die, trimming die, cutting die, etc.
(2) Bending mold It is a mold that makes the sheet blank or other blanks bend and deform along a straight line (bending line) to obtain a certain angle and shape of the workpiece.
(3) The drawing die is a die for making the blank of the sheet into an open hollow part, or to further change the shape and size of the hollow part.
(4) Forming mold is a mold that directly replicates the blank or semi-finished workpiece according to the shape of the convex and concave molds, and the material itself only produces local plastic deformation. Such as bulging molds, necking molds, flaring molds, undulating forming molds, flanging molds, shaping molds, etc.

Process combination

• (1) Single-process mold In one stroke of the press, only one stamping process mold is completed.
• (2) The compound mold has only one station, in one stroke of the press, in the same station
  On the mold that completes two or more stamping processes at the same time.
• (3) Progressive die (also called continuous die) In the feeding direction of the blank, there are two or more stations. In one stroke of the press, two or two passes are completed successively at different stations. Die for more than one stamping process

Continuous die (progressive die), the press uses strip-shaped stamping raw materials in one stamping stroke. Several different stations are used on a pair of molds to complete multiple stamping processes at the same time. Each stamping process is completed once. , The material belt moves once at a fixed distance until the product is completed.
During the stamping process of the continuous die, the material strip always moves in one direction; the material inside the die is cut and then moves in two or more directions called progressive die; the material where the material is fed inside the die is called automatic continuous die; A stamping production chain uses robots or other automated facilities for stamping dies with different processes, using dies or parts to move to complete the stamping of the workpiece. The rated dies are called multi-station dies.
