Problems solved by technology
At present, spiral fin tubes are widely used as heat exchange elements in various heat exchange environments. For example, in the steering system of heavy trucks, the spiral fin tubes are used as condensation pipes for the oil circuit in the steering system to dissipate heat from the return oil in the steering system. Due to the particularity of the assembly environment of the steering system of heavy-duty trucks, different from ordinary spiral finned tubes, the spiral fins of this spiral finned tube must be arranged on the heat sink in sections, and the cooling fins required for each section of spiral fins The quantity is different. In the traditional manufacturing process of the multi-section spiral finned tube, a winding machine is used to process it manually, and the number and length of the spiral fins are controlled by manually measuring the size. Therefore, it is difficult to control the number of heat dissipation fins in each section of spiral heat dissipation fins and ensure that the distance between adjacent heat dissipation fins is consistent, the production efficiency is low, and the yield of multi-section spiral heat dissipation fin tubes produced is low

Description
technical field [0001] The invention relates to the technical field of processing equipment for metal heat dissipation pipes, in particular to a multi-stage positioning and quantitative manufacturing process for heat dissipation fins and tooling thereof. Background technique [0002] The spiral finned tube is a high-efficiency heat transfer element. In order to improve the heat exchange efficiency, usually a heat sink is installed on the surface of the heat pipe to increase the outer surface area of the heat pipe, so as to achieve the purpose of improving the heat exchange efficiency. Its The heat transfer area is several times to dozens of times that of the heat pipe, which can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economy and operational reliability of heat exchange equipment. At present, spiral fin tubes are widely used as heat exchange elements in various heat exchange environments. For example, in the steeri...
