Rolling riveting equipment for thin heat dissipation fins and thin cover plate

Abstract

The invention discloses rolling riveting equipment for thin heat dissipation fins and a thin cover plate. The rolling riveting equipment comprises a workbench, a feeding frame, a driving device and acontrol box; the feeding frame is arranged on the workbench in a transverse back-and-forth moving mode; the driving device is arranged on the workbench and used for driving the feeding frame to transversely move back and forth; and a rolling device is arranged at the rolling riveting position of the workbench and used for conducting rolling riveting on the convex portions when the thin heat dissipation fins and the thin cover plate pass through the rolling device. According to the rolling riveting equipment for the thin heat dissipation fins and the thin cover plate, the control box controls the driving device, the driving device drives the feeding frame to move, the rolling device is arranged in a matched mode, when the feeding frame carrying a heat dissipation base, the thin heat dissipation fins and the thin cover plate passes through the rolling device, the rolling device rolls the convex portion of each thin heat dissipation fin, the convex portions are riveted into correspondingriveting holes, therefore, the thin cover plate and the thin heat dissipation fins are fixed together, the assembling efficiency is greatly improved, manpower consumption is reduced, and meanwhile theproduct reject ratio is effectively decreased.

Description

technical field [0001] The invention relates to the technology in the field of radiator manufacturing equipment, in particular to rolling riveting equipment for thin heat dissipation fins and thin cover plates. Background technique [0002] The heat sink usually includes a heat dissipation base and heat dissipation fins arranged on the heat dissipation base. In order to improve the heat dissipation effect, the current heat sink generally adopts thin heat dissipation fins, and because the strength of a single thin heat dissipation fin is weak, it is easy to deform. Therefore, it is necessary to install thin cover plates on multiple thin heat dissipation fins to enhance the overall strength of the heat sink. In the prior art, manual welding is mostly used for the assembly of thin cover plates. This assembly method is not only inefficient and labor-intensive, but also the thin cover plates are easily welded through, resulting in defects. Therefore, it is necessary to study a s...
