Edge overturning device with sawtooth-shaped compressing block, edge covering device and edge covering method

Abstract

The invention provides an edge overturning device with a sawtooth-shaped compressing block. The edge overturning device with the sawtooth-shaped compressing block is used for overturning a corner portion edge material located on the corner portion of a skylight opening portion and an edge portion edge material located on the edge portion of the skylight opening portion from the inner surface of the skylight opening portion to the outer surface, wherein the corner portion edge material located on the corner portion of the skylight opening portion and the edge portion edge material located on the edge portion of the skylight opening portion are in decoration fabric stuck to the inner surface of the skylight opening portion of an automobile interior ceiling; at least one edge of the four edges of the skylight opening portion is a rightward-right-angle-U-shaped edge, and the remaining sides are L-shaped edges; and the edge overturning device comprises a framework mechanism corresponding tothe size of the skylight opening portion, a flat pushing mechanism arranged on the outer side of the rightward-right-angle-U-shaped edge, and a control mechanism controlling the framework mechanism and the flat pushing mechanism to act. The edge overturning device can correspondingly perform edge overturning on the corner portion, the rightward-right-angle-U-shaped edge and the L-shaped edges ofthe skylight opening portion, and wrinkling is not likely to be caused during edge overturning. The invention provides an edge covering device with the edge overturning device with the sawtooth-shapedcompressing block. The invention provides an edge wrapping method used for performing edge covering on the skylight opening portion of the automobile interior ceiling.

Description

technical field [0001] The present invention relates to a flanging device, hemming equipment and hemming method with sawtooth-shaped pressing blocks, and in particular to a method for turning out the decorative fabric stuck on the inner surface of the sunroof opening of the roof of the automobile interior trim. A flanging device with sawtooth-shaped pressing blocks on the outer surface of a skylight opening, an edge wrapping device, and an edge wrapping method. Background technique [0002] During the processing of the semi-finished car interior canopy, the decorative fabric pasted on the inner surface of the sunroof opening of the semi-finished interior canopy needs to be turned from the inner surface of the sunroof opening to the outer surface of the sunroof opening, and the same as that of the sunroof opening The outer surfaces are bonded. Flanging devices are now used to automate this step. [0003] Flange devices in the prior art such as "flange device and hemming equ...

AI Technical Summary

Problems solved by technology

[0005] 1. When the corner flanging block and the side flanging block of the flanging device in the prior art are flanging, because the edge material is in a free state, the edge material is likely to move during flanging, so that the flanging after flanging The edge material is wrinkled, especially the corner of the skylight opening has a special shape, and the edge material at the corner will be stretched by the corner of the skylight opening when flanging. In this case, wrinkling is more likely to occur after flanging

[0006] Two, the flanging device in the prior art is only applicable to the situation that the edge of the skylight opening is an L-shaped edge, but in fact, due to actual needs, the edge of the skylight opening can sometimes be designed as a U-shaped edge, so in the package It is also necessary to hem the upper and lower surfaces of the upper part of the rim, but the above-mentioned flanging device cannot hemm the rim of the skylight opening at all.
