Technique for riveting base plate of radiator and fins

Abstract

In the riveting technique, forming mould is installed in clamp. There are multiple punches in the forming mould. Fin is composed of multiple sheets, and there is prearranged gap between adjacent fins. Fins can be inserted and positioned in the forming mould. Fins and punches are staggered set up. Floor plate with grooves is positioned on the clamp. Punch press pushes back face of floor plate to make fins plant and position on the grooves. Being pushed by punches, surface of floor plate on two sides of fins generates deformation so as to rivet and solidify fins. Comparing with prior art, the invention reduces breakdown of the forming mould effectively, raises rate of good products, precision, and quality.

Description

technical field

[0001] The invention relates to a riveting process of a heat sink base plate and fins, in particular to heat sinks applied to integrated circuits or electronic equipment, and the riveting process of the base plate and fins of the heat sink, mainly inserting and installing the fins In the molding die in the jig, the bottom plate is set on the jig corresponding to the top surface of the fins, and the punching machine impacts the bottom plate and rivets and consolidates it into one body. Background technique

[0002] Generally used for radiators for integrated circuits or electronic equipment, including a base plate and a heat sink, the base plate is formed with many grooves, and the fins and grooves are correspondingly plugged and planted on the base plate. In the prior art, the fins are fixed on the base plate method (see figure 1 ), the bottom plate 10 of the heat sink 1 is preformed with grooves 11, the bottom plate 10 is fixed on a jig (not shown in the fi...
