Skylight lateral shaping die

Abstract

The invention belongs to the field of automobile body sheet metal manufacturing, and particularly relates to a skylight lateral shaping die, which comprises a male die opposite to the inner side of the flange of a skylight, and a female die opposite to the outer side of the flange of the skylight, wherein the male die and the female die are respectively arranged on a lower die base slidably; an open-close type structure is formed between the male die and the female die; the male die and the female die are respectively driven by an inclined wedge driver block on an upper die base; the lower die base is also provided with a push rod for transmitting driving force of the inclined wedge driver block to the male die; the push rod extends to the outer side of the edge of a top cover through the lower part of the top cover from the skylight position; the push rod and the inclined wedge driver block form transmission fit on the outer side of the edge of the top cover. According to the skylight lateral shaping die, when the top cover without the skylight is produced, the skylight lateral shaping die can avoid the top cover, so that the skylight lateral shaping die has no need to be disassembled, the production efficiency is improved, and the risks of workpiece scrappage and die damage caused by misoperation are eliminated.

Description

technical field [0001] The invention belongs to the field of automobile body sheet metal manufacturing, and in particular relates to a sunroof side shaping die. Background technique [0002] The manufacture of the car top cover generally needs to go through four processes, namely drawing, trimming, front flanging, and shaping. for connecting other body parts. This shaping process is generally carried out for the edge flanging of the top cover and the edge flanging of the skylight. [0003] Most of the production lines of automobile OEMs have only four stamping machine tools, requiring parts to be completed in up to four processes. However, the skylights on the roof of most models have negative angles on all four sides, see figure 1 In the top cover 40 shown, three sides 411 , 412 , 413 of the skylight 41 are edged by molds, and the remaining edge is hemmed by a robot. Since the four sides of the skylight 41 have gone through three processes, i.e., drawing, trimming, and ...

AI Technical Summary

Problems solved by technology

Their principles are similar. When producing a roof with a skylight, some molds need to pass through the skylight. This means that if you want to produce a roof without a skylight, you need to remove the mold that passes through the skylight. It can be seen that The defects of the above-mentioned molds are: 1) manual operation is required to switch the structure, which increases the workload of personnel, reduces production efficiency, and causes the risk of scrapped parts and mold damage caused by personnel misoperation; 2) the switching structure is complicated, resulting in the cost of mold production High, the reliability of the structure is reduced, and the maintenance cost and the quality risk of the parts are increased
