Embodiment approach
[0047] As a specific embodiment of the present invention, the compensator 22 includes a plurality of stacked first half-rings 221 and a plurality of stacked second half-rings 222, through a plurality of first half-rings 221 and the second The superposition of the No. 1 semi-ring 222 reduces the adjustment error, improves the compensation accuracy, and improves the quality of the multi-step sheet metal parts. The No. 1 semi-ring 221 and the No. 2 semi-ring 222 are combined end to end to form a complete ring. The No. 1 half ring 221 and the No. 2 half ring 222 are fixedly connected to the rotating shaft 11 by screws, which facilitates the installation or removal of the compensator 22 .
[0048] Working principle: first, replace the extruded plate 54 as required, and replace the extruded plate 54 with the required size by unscrewing the screw between the reinforced plate 53 and the extruded plate 54 on the convex roller 1. The size change of 54 makes the adjacent sides of the ext...

The invention discloses an automobile metal plate stamping die. The automobile metal plate stamping die comprises a convex roller and a concave roller, the convex roller is matched with the concave roller, the convex roller comprises a rotating shaft, an annular groove is formed in the middle of the rotating shaft, a plurality of first T-shaped grooves, second T-shaped grooves and containing cavities are formed in the positions, at the bottom of the annular groove, of the rotating shaft, first bosses are fixed in the first T-shaped groove and the second T-shaped groove through a plurality of clamping blocks, and a second boss is slidably connected in the containing cavity. The multi-step sheet metal part is produced in a rolling mode of the convex roller and the concave roller, the mode that the multi-step sheet metal part is obtained through a die in the traditional process is replaced, the multi-step sheet metal part can be continuously produced through a long sheet metal part in the mode, the number of times of clamping and disassembling the sheet metal part is reduced, and the production rate is increased; and by adjusting the position of the first boss on the convex roller, the size of the multi-step sheet metal part is adjusted, and the cost for producing dies of different sizes is reduced.
Description
technical field [0001] The invention relates to the technical field of dies, in particular to an automobile sheet metal stamping die. Background technique [0002] Sheet metal, a processing technology, sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: sheet metal is a comprehensive cold processing process for metal sheets (usually below 6mm), including shearing, punching / cutting / compositing, folding, riveting, splicing, Forming (such as car body), etc. Its remarkable feature is that the thickness of the same part is consistent. [0003] The publication number is CN111408663A, a sheet metal stamping die, comprising a frame, an upper template, a lower template, a first stamping die, a second stamping die and a third stamping die; the hydraulic press and the lower template are erected on the frame, and the upper The template is slidingly connected with the connecting column of the ...
