Sheet metal part stamping hole correcting device and method

Abstract

The invention discloses a sheet metal part stamping hole correcting device and method and relates to the technical field of automobile manufacturing. The sheet metal part stamping hole correcting device comprises a shape correcting press cake and a shape correcting bottom block, wherein the shape correcting press cake and the shape correcting bottom block are mounted on a screw rod through threads; and a handle capable of pushing the shape correcting press cake to move on the screw rod is arranged on the shape correcting press cake. The sheet metal part stamping hole correcting method comprises the following specific steps: A, penetrating the shape correcting bottom block through a sheet metal part stamping hole to move the shape correcting bottom block to the to-be-corrected part on the edge of the sheet metal part stamping hole; B, enabling the shape correcting press cake to move along the screw rod to press the edge of the sheet metal part stamping hole to be flat; and C, enabling the shape correcting press cake to move along the screw rod to be separated from the sheet metal part, and taking the sheet metal part stamping hole correcting device out. Compared with the prior art,the sheet metal part stamping hole correcting device is easy to operate even if operation is carried out on the single side of a car body in a small and narrow space, the flatness of the hole edge isensured after repairing and correction, only 20 seconds are needed for repairing and correcting one hole, the working efficiency is greatly improved and the labor cost is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a correction device and a correction method for stamping holes of sheet metal parts. Background technique [0002] When the floor skin is installed on the welding floor line of the car body or the lower body line, the floor skin is installed and positioned through the positioning holes on it. The aperture diameter of the positioning hole is φ>25mm, and the floor skin is punched with sheet metal parts to process the positioning holes. Due to the thinness of the sheet metal parts, the stamping holes of the sheet metal parts are easily deformed and the edges of the holes are not smooth, so the punching holes of the sheet metal parts need to be repaired and corrected. Because there is no special correction device for stamping holes in sheet metal parts, operators currently repair and correct the punching holes of sheet metal parts manually. It is difficult to work...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned tasks of the present invention are all aimed at solving the problems of manual repair and correction of sheet metal stamping holes, difficulty in ensuring the flatness of the edge of the hole after repair and correction, low work efficiency, and high labor costs.
