The heat exchanger fins can be positioned through the stamping receding grooves, the stamping precision of the heat exchanger fins can be ensured, and later assembly of a heat exchanger is facilitated; the heat exchanger fin stacking and collecting device can stack and collect punched heat exchanger fins, and machining steps can be reduced.

Description

technical field [0001] The invention relates to the technical field of ground source heat pumps, in particular to a manufacturing and processing equipment and a manufacturing and processing method for heat exchanger components of a ground source heat pump. Background technique [0002] Ground source heat pump is a device used to realize the transfer from low-grade heat energy to high-grade heat energy. Ground source heat pump is a heating central air-conditioning system composed of ground source heat pump unit, building system and geothermal energy exchange system. Among them, geothermal energy The main component in the exchange system is the heat exchanger assembly, which is mainly used to exchange heat between fluids of different temperatures.

AI Technical Summary

Problems solved by technology

[0003] During the processing of heat exchanger components, it is necessary to make corresponding heat exchanger fins according to the type of heat exchanger components. Heat exchanger fins are generally made of metal sheets through stamping process, and through existing stamping Stamping the fins of the heat exchanger by means of stamping, not only many procedures, low production efficiency, but also poor molding quality and high scrap rate

[0004] For the problems of low stamping efficiency and poor molding quality of heat exchanger fins mentioned above, corresponding solutions have been proposed in the prior art. Stamping die from the boss, the die realizes the stamping of the boss from the fin of the heat exchanger through three processes of tearing, primary bending and secondary bending, with low scrap rate and good product surface forming quality consistency characteristics, and can improve production efficiency

[0005] However, the above-mentioned stamping die also has the following problems: 1. The guide and positioning device of the heat exchanger fins are not provided in the above-mentioned stamping die, so when the stamping die stamps the heat exchanger fins, it is impossible to ensure that the heat exchanger fins The stamping accuracy of the heat exchanger fins cannot be accurately stamped, which affects the later assembly of the heat exchanger fins

[0006] 2. The above stamping die cannot process heat exchanger fins of different thicknesses, so there are limitations, and the stamping die cannot stack and collect the processed heat exchanger fins, so after the heat exchanger fins are stamped , they need to be removed one by one, which increases the processing steps and affects the processing efficiency
