Flanging device with serrated pressing block, hemming device and hemming method

Abstract

The invention provides a flanging device with a zigzag pressing block, which is used to separate the corner edge material located at the corner of the sunroof opening of the decorative fabric adhered to the inner surface of the sunroof opening of the automobile interior roof and the edge material located at the corner of the sunroof opening. The edge material at the edge of the skylight opening is turned over from the inner surface of the skylight opening to the outside. On the surface, at least one of the four sides of the skylight frame opening is a U-shaped side, and the remaining sides are L-shaped sides. The flanging device includes a frame mechanism corresponding to the size of the skylight opening, and a flat pusher arranged outside the U-shaped side. mechanism and the control mechanism that controls the action of the frame mechanism and the push mechanism. The flanging device of the present invention can flange the corners, U-shaped edges and L-shaped edges of the skylight opening respectively, and it is not easy to wrinkle during flanging. The invention provides a hemming equipment having the above-mentioned flanging device with a zigzag pressing block. The invention provides a hemming method for hemming the sunroof opening of a car interior roof.

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.
