Thinning and stretching of metal stamping and drawing parts is more commonly used in the drawing process, and it is committed to completing the forming of extremely thin-walled cup-shaped parts or the forming of extremely thin-walled pipes. The following is a detailed introduction to the thinning and stretching characteristics of metal stamping and drawing parts. Only by grasping and understanding this characteristic can you complete the production and processing theme activities faster.

Commonly used raw materials for thinning and stretching are: copper, aluminum, aluminum alloy profiles, high carbon steel, stainless steel plates, etc.

(1) Concave, the distance between the two mold bases is lower than the thickness of the blank, and part of the straight wall of the blank is pressed according to the gap, resulting in a significant thinning phenomenon, while Increase the aspect ratio of the outer wall.

(2) There is no problem of wrinkling, and no edge wrapping equipment is required.

(3) The quality of the thinned and drawn parts is high, the wall thickness is relatively uniform, the wall thickness error is within ±0.01mm, and the surface roughness Ra value is below 0.2um. And because of the two-way compression, the crystal is fine and the compressive strength is improved.

(4) The internal stress of the thinned and drawn parts is relatively large, and some even crack during the storage process. This phenomenon can be eliminated by ultra-low temperature quenching.

Thinning and drawing, stainless steel plate drawing, stamping drawing, casing drawing, deep drawing, all kinds of complicated and fine metal stamping and drawing parts.
