Problems solved by technology

[0003] The stamping and riveting method of the bottom plate and fins of the existing radiator has the disadvantages of easy breakage of the molding die, high cost, yield and accuracy of the finished product, and cannot meet the economic benefits of the industry and meet the needs of the radiator. Therefore, the development of a New technology to solve the aforementioned shortcomings is an important issue

Embodiment Construction

[0024] See first Figure 2 ~ Figure 3 As shown, the riveting process of a radiator base plate and fins in the present invention includes a jig 2, the jig 2 is formed with a hollow 21, and the forming mold 3 is installed in the hollow 21 of the jig 2, and the molded The mold 3 is integrally provided with a plurality of punches 31 arranged in sequence. The punches 31 are extended from the molding die 3 to have a predetermined height. The fins 4 are composed of a plurality of fins. The operation is combined into a single body, there is a predetermined gap between adjacent fins 4, and the fins 4 can be inserted into the molding die 3 for positioning, so that the fins 4 and the punches 31 are adjacent to each other, and a bottom plate 5, its surface A corresponding groove 51 is formed at the joint end of the fin 4, and the bottom plate 5 is positioned on the jig 2 (such as Figure 4 ), the fins 4 have to be plugged in correspondingly with the grooves 51, and the punches 31 are clo...

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...
