Problems solved by technology

[0002] In the process of cold stamping forming, when stamping and bending strips with arc-shaped cross-sections, the surface of the stamping parts often has cracks, wrinkles, and stacking. These phenomena will affect the appearance, quality, and even the appearance of the finished product. The finished product will be scrapped. At present, the measures taken are to reinforce, pack, and draw grooves on the shape surface during stamping, and even add a pre-forming process, but the desired effect is still not achieved.

Embodiment Construction

[0018] see Figure 1-3 It can be seen that the cold stamping auxiliary tool is the gasket 3 located between the stamping part 4 and the punch 1, and the stamping part 4 is a metal sheet that has been stamped once and has a circular arc shape, a wave shape, or a special-shaped arc shape. , during the secondary stamping, it is necessary to complete the bending stamping process in a different direction from the first bending stamping under the stamping of the punch 1 and the die 2 of the present invention. Before the die 2 is closed to the bottom, these excess materials will accumulate in the gaps of the mold, and when the mold is closed to the bottom, these excess materials will be superimposed together to form stacks or folds. After the gasket 3 is added between the stamping part 4 and the punch 1, the gap between the stamping part 4 and the mold before the mold is closed can be eliminated, and the stamping part 4 is forced to follow the shape in a flat and full state all the t...

Abstract

The invention discloses a cold stamping assistive device and a stamping process thereof. The assistive device is a gasket located between a stamping piece and a convex mold; the contact surface of the gasket and the stamping piece is matched with the stamping piece in shape; and the contact surface between the gasket and the convex mold is a plane. With the adoption of the assistive device and a machining method, the product quality is improved; after being shaped, a product which is stamped by using the process can meet the requirements of components, so as to meet the requirements of clients; and moreover the working procedures are reduced; and the cost is reduced.

Description

technical field [0001] The invention relates to the field of cold stamping, more specifically, to an auxiliary tool for stamping and bending arc raw materials and a stamping process thereof. Background technique [0002] In the process of cold stamping forming, when stamping and bending strips with arc-shaped cross-sections, the surface of the stamping parts often has cracks, wrinkles, and stacking. These phenomena will affect the appearance, quality, and even the appearance of the finished product. The finished product will be scrapped. The measures taken at present are to reinforce, pack, and draw grooves on the shape surface during stamping, and even add a preforming process, but the desired effect cannot be achieved. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a stamping auxiliary tool and a process method thereof that can ensure that the arc-shaped strips are stamped and bent without cracking, wrinkling,...
