Abstract

The invention discloses a heat exchanger aluminum fin stamping die, which includes an upper template and a lower template. The above-mentioned upper template is provided with a circular die cavity into which the ball-end punch can be inserted correspondingly. The purpose of the invention is to overcome the shortcomings of the prior art and provide a heat exchanger aluminum fin stamping die with low production cost and good aluminum foil stamping quality.

Description

【Technical field】 [0001] The invention relates to an aluminum fin stamping die. 【Background technique】 [0002] The aluminum fins of the heat exchanger are mounted on the heat dissipation pipes. In order to enhance the heat dissipation capacity, flanging is provided on the perforated side of the aluminum fins to increase the contact area between the aluminum fins and the heat dissipation pipes. The existing heat exchanger aluminum fin stamping die can only punch aluminum foil with a thickness of 0.095, which has high production cost, cracks will occur around the perforation of the punched aluminum foil, and the product quality is poor. 【Content of invention】 [0003] The object of the invention is to overcome the disadvantages of the prior art and provide a heat exchanger aluminum fin stamping die with low production cost and good aluminum foil stamping quality. [0004] The present invention is achieved through the following technical solutions: [0005] A stamping die ...
