Plate stretching and punching die

Abstract

The invention discloses a plate stretching and punching die. The die comprises an upper die base, a lower die base, a male die, a female die, a punch, a pressing plate and a stripping block, a lower padding plate is arranged on the lower die base, an upper padding plate is arranged on the upper die base, the male die is fixed to the lower padding plate through a fixing plate, and the female die isinstalled on the upper padding plate and matched with the male die to complete product side drawing forming. A center hole is formed in the male die, the punch is fixed to the upper padding plate andmatched with the center hole to complete product punching, a first nitrogen spring is arranged on the lower die base, the pressing plate floats between the upper die base and the lower die base underthe action of the first nitrogen spring, the pressing plate is matched with the female die to clamp the outer ring of a plate, and a second nitrogen spring is arranged on the upper die base. The stripping block floats between the upper padding plate and the pressing plate under the action of the second nitrogen spring and is matched with the male die, so that the inner ring of the plate is clamped. The die is accurate in forming size, high in efficiency, low in cost and convenient to release.

Description

technical field [0001] The invention relates to the technical field of sheet material processing, in particular to a sheet material stretching and punching die. Background technique [0002] process the sheet into figure 2 The products shown are generally formed by drawing process, but there are the following problems in the drawing process of sheet metal: first, in terms of products, the forming effect of the sheet after stretching is not good, and the forming size is inaccurate; second, in terms of technology, stretching And punching is usually carried out step by step, the equipment cost is high, the processing efficiency is low, and the upper step process is easy to affect the next step process, therefore, further improvement is needed. Contents of the invention [0003] The purpose of the present invention is to provide a stretching and punching die for sheet metal, which ensures the effect of stretching and forming, and at the same time completes the punching proces...
