Floating sizing die

Abstract

The invention discloses a floating sizing die, which comprises an upper template, an upper die cutter block, a lower template, a lower die cutter block, a guide part and a floating sizing cutter block transversely arranged between the upper die cutter block and the lower die cutter block. Negative angle forming parts which are matched and used for generating negative angles by extruding a U-shaped punching piece are arranged on the upper die cutter block, the lower die cutter block and the floating sizing cuter block. The U-shaped punching piece is sleeved on the negative angle forming parts of the floating sizing cuter block. By adopting the technical proposal, the problem of incapability of producing the U-shaped punching piece with the negative angle in the prior art can be well solved; the die is simple in structure and high in production efficiency and capable of punching and forming at one time; the accumulative tolerance caused by fractional assembly can be avoided; the productprecision is increased; the tooling number is reduced; the process is shortened; and the production cost and the production and quality control difficulty can be reduced.

Description

technical field [0001] The present invention relates to automotive cold stamping dies, in particular. The invention relates to a floating plastic mold. Background technique [0002] At present, for stamping parts with negative angles on automobiles, such as U-shaped parts formed into stamping parts with negative angles, it is difficult to stamp and form the general cold stamping dies, resulting in the inability to manufacture the parts, so that the parts need to be reworked. Development, the existing method is to assemble parts separately. Sub-assembly not only increases the number of tooling, but also prolongs the process flow, and because the cumulative tolerance will also reduce the accuracy of the product, so sub-assembly is very unfavorable to production organization, cost control and quality control. Contents of the invention [0003] The technical problem to be solved by the present invention is a floating plastic mold to produce "U"-shaped stamping parts with neg...
