Stamping part reshaping die

Abstract

The invention discloses a stamping part reshaping die and relates to the technical field of a die structure, aiming at realizing the upward large-angle adjustment of a stamping part and the decrease of stamping cost. The stamping part reshaping die comprises an upper die holder and a lower die holder, wherein the upper die holder is provided with an upper die punch; the upper die punch is provided with an upper adjustment face which is the same as the after-reshaping upper surface of a reshaping part in the stamping part; the lower die holder is provided with a lower die punch; the lower die punch is connected with a first nitrogen spring driving the lower die punch to move; the lower die punch is provided with a lower adjustment face which is the same as the after-reshaping lower surface of the reshaping part in the stamping part; the first nitrogen spring is used for driving the lower die punch to slide and approach the upper die punch, and in the case of die assembly, enabling the lower adjustment face and the upper adjustment face to be mutually close to the reshaping part of the stamping part in a matching way. The stamping part reshaping die is mainly used for reshaping the stamping part.

Description

technical field [0001] The invention relates to the technical field of mold structures, in particular to a stamping part shaping mold. Background technique [0002] The stamping process mainly includes blanking, bending, shearing, deep drawing, bulging, spinning, shaping and other processes, among which the shaping process is to use the established plastic mold to perform secondary trimming on the shape of the product. For example, in the production of automobile stamping, the structure of the outer cover of the car is relatively complicated, and a shaping process is usually required to make the outer cover meet the design requirements. [0003] For some outer coverings with complex profiles, such as side panels, fenders, roofs, tailgates, door panels, etc., generally have negative angle parts. When shaping these outer coverings, The upward shaping of the negative angle part needs to be realized through the wedge mechanism arranged in the shaping mold. The wedge mechanism ...

Problems solved by technology

However, when the negative angle is 15°, since the slider is driven by the wedge, the relative movement between the slider and the wedge will be stuck and frustrated, which makes it difficult for the slider to align the stamping parts. Large upward angle (negative angle greater than 15°) adjustment

In order to achieve a large upward adjustment, the prior art also provides a rotating mechanism, through which the punching angle of the stamping part is rotated, and when the punching angle of the wedge is met, the upward large angle adjustment can be realized, but this is undoubtedly an increase. The process steps are shortened, which increases the production time of stamping parts, which in turn increases the cost of stamping
