Problems solved by technology

[0003] Generally, during processing, due to the width limitation of raw materials, when a wider heat sink is required, two splicing combinations are required. During the combination process, the heat sink needs to be clamped and fixed, which often damages the heat sink and affects the shape of the heat sink after forming. product quality

Embodiment Construction

[0040] The present application will be further described in detail below with reference to the accompanying drawings.

[0041] The present application discloses a method of producing a heat sink for stirring friction, including the following steps:

[0042] Decreased, cutting the long raw material into a plurality of short films, the length of the long raw material is 5m, and the length of the automatic lowering machine is required to be cut, the length of the short material is 400 mm in this embodiment, when cutting The long raw material is pressed, and the length of the cutting needs to be cut, and the short film is cut by a cutter.

[0043] The calibration end surface is then performed, and the heat dissipating fin 12 is formed by the calibration clamp, and the substrate 11 is fixed by the clamp, so that the calibration clamp is relatively moved with the heat sink, and the heat dissipating fins 12 are calibrated to each other. The state is cut, and the heat dissipating fin 12 i...

Abstract

The invention relates to the technical field of cooling fin manufacturing, in particular to a method for producing a cooling fin through friction stir welding, which comprises the following steps: shortening: cutting a long raw material into a plurality of sections of short materials; connecting, specifically, the two short materials are clamped side by side, so that the heat dissipation fins on the two short materials are arranged side by side, and the connecting edges of the short material substrates are welded and fixed through a friction stir welding head; when two short materials are arranged in parallel, clamping and fixing force is only applied to substrates of the short materials. Compared with the prior art, the friction stir welding method has the following effects that the two short materials are welded and fixed through friction stir welding, meanwhile, only the base materials are clamped in the clamping process, acting force is not applied to the cooling fins, cooling fins on the obtained finished cooling fins can be kept good, and the overall quality is improved.

Description

Technical field [0001] The present application relates to the technical field of heat sink manufacturing, and more particularly to a method of producing a heat sink for stirring friction welding. Background technique [0002] The heat sink is widely used in major industries, and the general heat sink is aluminum, reference figure 1 , Including the substrate 11, a plurality of heat-dissipating fins 12 are machined on the substrate 11, typically processed on the substrate 11, and the heat sink is mounted to the thermal portion, and the heat dissipating fin can be better. out. [0003] Generally, during processing, due to the width of the raw material, when a wider heat sink is required, it is necessary to combine two splicing, in the combination, it is necessary to fix the heat sink, often damage the heat dissipating fin, affecting the molding Product quality. Inventive content [0004] In order to be fixed, the damage to the heat dissipating fins is reduced, and the present appli...
