Side enclosure outer plate tail springback control structure

Abstract

The invention belongs to the technical field of automobiles, and particularly relates to a side enclosure outer plate tail springback control structure. The structure comprises a first positioning block, a second positioning block, a third positioning block, a rotating block, a supporting block, a connecting block, an air cylinder and a clamp base. The first positioning block is fixed to the supporting block; the second positioning block is fixed to the supporting block through the connecting block; the third positioning block is fixed to the lower end of the rotating block; the rotating blockis connected with a movable end of the air cylinder; the air cylinder is fixed to the supporting block; the supporting block is fixed to the clamp base through a connecting plate; and the positioningblock attracts a side enclosure outer plate part. With the side enclosure outer plate tail springback control structure, the dimensional accuracy of the side enclosure outer plate part can be effectively controlled in the welding process, and the debugging period can be remarkably shortened.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a rear rebound control structure of a side wall outer panel. Background technique [0002] As the outer covering of the car, the side wall outer panel is located in the visually intuitive area. The size of the body lap is very important. The rear area is the key position of the lap with the rear door and taillights, and the body size is strictly required. [0003] At present, although the tail area of ​​the side wall outer panel is in the design stage, through simulation analysis, the theoretical springback amount is compensated, but the springback compensation work is difficult and the cycle is long, and due to the gap between the actual working state of the mold and the theory, it is limited Due to the influence of equipment accuracy, mold research and matching status, sheet material performance, etc., the springback compensation effect is poor, and there is more or less sp...

[0003] At present, although the tail area of ​​the side wall outer panel is in the design stage, through simulation analysis, the theoretical springback amount is compensated, but the springback compensation work is difficult and the cycle is long, and due to the gap between the actual working state of the mold and the theory, it is limited Due to the influence of equipment accuracy, mold research and matching status, sheet material performance, etc., the springback compensation effect is poor, and there is more or less springback in the tail area of ​​the side wall outer panel

[0004] According to the traditional change plan, after the size deviation of the actual part, the mold needs to be changed, and the springback compensation needs to be changed in the dra
