Abstract

The invention provides a manufacturing process for the fins of the air-conditioning condenser. The manufacturing and processing of the fins of the air-conditioning condenser are fully cooperated with the stamping die and the like. When processing fins of different sizes, different molds need to be replaced, the processing range is small, and the processing efficiency is low; at the same time, the existing equipment is affected by the special structure of the fin itself when processing the fin, which causes the fin to be tightly attached to the fin after processing. On the mold, it is inconvenient to take the material after the processing is completed; and the raw material will be retracted by force during the processing of the fin. Due to the improper limiting method of the fin, the fin will be offset during processing, resulting in the processing of the fin. After completion, there are problems such as deformation and breaking.
