Fast assembly, rolling riveting and bending integrated forming method and device

Abstract

The invention discloses a fast assembly, rolling riveting and bending integrated forming method and a riveting device. The method comprises the following steps that an inclined pushing device pushes an inclined comb plate to move to comb and centralize cooling fins, so that when a cover plate covers the cooling fins, riveting convex points on the cooling fins can be aligned with and matched with riveting holes in the cover plate one by one; then, a riveting and bending screw rod driving mechanism drives a rolling riveting device and a bending device to move simultaneously, during pushing out,the rolling riveting device carries out riveting pressing on the riveting convex points on the cooling fins, and thus the purpose of rolling riveting is achieved; and during pulling pack, the bendingdevice is used for bending the edge position of the cover plate, so that the bending purpose is achieved. Therefore, the centralizing function, rolling riveting function and bending function can be rapidly achieved through one-time clamping, the operation process is effectively simplified, the operation is easy and convenient, time and labor are saved, the working efficiency is improved, meanwhile, the consistency of the riveting effect and bending effect is guaranteed, and finally, the yield is improved.

Description

technical field [0001] The invention relates to the technical field of riveting and bending, in particular to a fast-installation rolling riveting and bending integral forming method and riveting equipment thereof. Background technique [0002] In some application fields, the heat sink and the cover plate need to be riveted and assembled. The traditional process is: the heat sink is riveted on the aluminum plate base in advance to form a heat dissipation module, and the heat dissipation module is placed on the jig. Before the riveting process, it is necessary to manually adjust the position of the heat sink on the aluminum plate base, and then cover the cover plate so that the riveting points on the heat sink are inserted into the riveting holes of the cover plate, and then the riveting points are riveted to achieve the purpose of riveting . [0003] However, the heat sink tends to shake during the process of manual adjustment and uprighting, and it is difficult to make the...

Problems solved by technology

[0003] However, the heat sink tends to shake during the process of manual adjustment and uprighting, and it is difficult to make the riveting points on the heat sink face the riveting holes on the cover plate. It is prone to tilting and shifting. At this time, it is necessary to adjust the position and straighten the heat sink again. Moreover, the number of heat sinks is as few as a few pieces, and most of them are tens or hundreds of pieces. It requires multiple people to adjust and align each piece, which is time-consuming. It is laborious, especially the cooling fins are arranged at an inclined angle, and the narrow operating space makes it difficult to manually adjust the position and straighten the operation. It is difficult to ensure the quality of rolling riveting, and it is easy to produce defective products.

[0004] At the same time, in order to realize the bending of the edge of the cover plate, it is necessary to move the whole body to the bending equipment for bending and forming or to perform the bending process on the cover plate in advance, which is troublesome and time-consuming.
