Embodiment 1

[0022] Such as figure 1 As shown, the present invention is used for edge wrapping of plane straight-edge aluminum alloy plates. 1 edging platen, 2 outer plate, 3 platen, 4 inner plate, 5 membrane.

[0023] Generally, aluminum alloy piping is divided into 3 passes. The outer plate is turned at 90 degrees, and the pressing angle is generally 30, 60, and 90 degrees. The plate flanging realizes the wrapping and pressing, so as to complete the task that the traditional hemming requires a roller to go back and forth 3 times and the attitude of the roller needs to be adjusted in the middle. Therefore, the hemming efficiency is greatly improved.

Embodiment 2

[0025] Such as figure 2 As shown, the invention is used for the hemming of flat straight-edged steel plates. 1 edging platen, 2 outer plate, 3 platen, 4 inner plate, 5 membrane.

[0026] Generally, the steel plate hemming is divided into 2 passes, the outer plate is turned at 90 degrees, and the pressing angle is generally 45 or 90 degrees. However, in this embodiment, the outer plate 2 is turned over by the hemming pressure plate in advance by setting the hemming pressure plate in advance. Complete the hemming, so as to complete the task of traditional hemming that requires a roller to go back and forth twice and adjust the attitude of the roller in the middle. Therefore, the hemming efficiency is greatly improved.

Abstract

The invention discloses a method and a structure used for increasing robot edge wrapping efficiency. One-step rapid edge wrapping is realized by arranging an edge wrapping press plate, and the molding quality is better than that of a roller. The structure combines the flexibility advantage of robot edge rolling and the high production efficiency advantage of press die-pressing edge wrapping and has great economical benefit and practical significance.

Description

technical field [0001] The invention relates to the technical field of connecting inner and outer panels of automobile covering parts, in particular to a method and structure of a robot hemming device. Background technique [0002] Robot rolling hemming is the latest hemming technology, which can plan the corresponding hemming path for parts of different shapes through trajectory programming. The new robot hemming technology not only has a small one-time investment and low cost of equipment, but also has beautiful shape, flexible manufacturing, short debugging cycle, small working area, and most importantly, short R&D and manufacturing cycle, which improves product competitiveness and is suitable for automobiles. The rapid development of the industry is in line with the development trend of flexible body production lines in the automobile manufacturing industry. It provides a solution for the multi-model mixed line production of the door cover line, adapts to the future devel...
