Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.

[0016] Such as figure 1 The structure of the present invention expressed is a thin plate riveting device for automobile door glass lifters, which is used for riveting two stacked metal thin plates. The figure shows the riveting of two metal sheets.

[0017] In order to solve the problems of damage to the surface coating of the thin metal plate due to welding and even the welding of the parts, and the difficulty of detection, the technical scheme adopted by the present invention is as follows:

[0018] Such as figure 1 As shown, the thin plate riveting device of the automobile door glass lifter of the present invention is provided with a riveting punch 1, a riveting die 2 and respectively connected with ...

Abstract

The invention discloses an auto door glass lifter sheet riveting device, which is provided with a riveting punch and a riveting die which are respectively connected with a press; in a riveting processing state, the riveting punch is pressed into one surface of two or more layers of stacked metal sheets, and bulges formed by an opposite metal sheet surface are pressed into a concave cavity of the riveting die; the cross section of the riveting punch is oval, and the cavity of the riveting die is matched with the shape of the cross section of the riveting punch. By adopting the technical scheme, the condition that two connected metal sheets fall off or get loose when being twisted on a plane is avoided; connection quality is easier to detect and control, a detection aim can be achieved by general detection ways, besides, riveting parameters are stable, fluctuation is not easy to cause, pollutants and radiation polluting environment and endangering human body health cannot be generated by riveting, and metal sheet part surface plating layer breakage and even welded part falling caused by welding are avoided. The technique is simpler, and the cost is lower.

Description

Technical field [0001] The invention belongs to the technical field of automobile door manufacturing. More specifically, the present invention relates to a riveting device for a thin plate of an automobile door glass lifter. Background technique [0002] In the prior art, welding is the most used for stacking and connecting metal sheets. However, the disadvantages of welding are also obvious. Its equipment is expensive and the connection cost is high. It is difficult to connect multi-layer plates and plated plates or aluminum, copper and stainless steel plates. Galvanized steel plate welding, high-strength steel plate welding and electroplating steel plate welding often Destroy the surface coating or even the welding of the parts, which affects the corrosion resistance of the plate, and there will be mechanical stress concentration phenomena, such as difficult detection. [0003] Especially when the two thin metal plates are twisted in the plane direction after welding, it is ea...
