Problems solved by technology
[0002] With the progress of society and the development of economy, more and more mechanically processed products appear in people's daily life, and stretched products are more common in mechanical products, but the quality of some stretched products is low and cannot meet people's needs. The use requirements, and how to improve the quality of stretched products has become the first difficult problem for producers to consider
[0003] In the prior art, during the mold closing process of the punch and the die, the pressing plate exerts too much pressure on the sheet material, which often causes the surface of the stretched product to break. When the die is ejected by the ejector device, the outer surface of the drawn product and the inner wall of the die are often worn, and then the outer surface of the drawn product is scratched, thereby affecting the quality of the drawn product

The invention discloses a drawing die preventing breakage in drawing. The drawing die preventing breakage in drawing comprises an upper die holder and a lower die holder which are correspondingly arranged. The lower surface of the upper die holder is provided with a concave die fixing block. The lower surface of the concave die fixing block is fixed with a drawing concave die. A drawing convex die corresponding to the drawing concave die is arranged above the lower die holder. A pressure plate is arranged above the lower die holder. A elastic pad is arranged between the lower die holder and the pressure plate. The drawing die preventing breakage in drawing has the advantages of simple in structure, reasonable in design, increasing the quality and precision of drawing product, convenient in operation, and convenient in popularization.
Description
technical field [0001] The invention relates to a stretching die, in particular to a stretching die for preventing stretching fracture. Background technique [0002] With the progress of society and the development of economy, more and more mechanically processed products appear in people's daily life, and stretched products are more common in mechanical products. However, the quality of some stretched products is low and cannot meet people's needs. How to improve the quality of stretched products has become the first problem that manufacturers have to consider. [0003] In the prior art, during the mold closing process of the punch and the die, the pressing plate exerts too much pressure on the sheet material, which often causes the surface of the stretched product to break. When ejecting the die with the ejector device, the outer surface of the drawn product and the inner wall of the die are often worn, and then the outer surface of the drawn product is scratched, thereby...
