Problems solved by technology

[0002] The progressive dies generally used in the processing of porous plates for parallel flow evaporators of automobile air conditioners are only suitable for the processing of porous plate parts with a single length specification; with product simplification, products of different specifications require different molds; when processing porous plate parts of different specifications It takes a long time to change molds and adjust molds, and the efficiency is low
The mold input cost is high; it seriously affects the production efficiency and production cost of the enterprise
In addition, the structure design of the porous plate in the prior art is unreasonable, resulting in poor structural strength of the porous plate and a high stamping waste rate

Abstract

The invention discloses a progressive die stamping device and process for a porous plate of an automobile air-conditioning parallel flow evaporator. A first station, a second station, a third station, a fourth station and a fifth station are arranged on the progressive die stamping device, and a material strap is manufactured into a finished product of the porous plate after passing through the first station, the second station, the third station, the fourth station and the fifth station. A die No.1 used for punching and puncturing is arranged on the first station, a die No.2 is arranged on the second station, a No.3 die is arranged on the third station, a No.4 die is arranged on the fourth station, and a die No.5 and a die No.6 customized cut-off are arranged on the fifth station. The upper dies of the die No.1, the die No.2, the die No.3, the die No.4, the die No.5 and the die No.6 form progressive die stamping upper dies, and the lower dies of the die No.1, the die No.2, the die No.3, the die No.4, the die No.5 and the die No.6 form progressive die stamping lower dies. The progressive die stamping device aims to ensure product diversification and reduce the input cost of dies, so that product parts are efficient, quick and error-proof in switching, and the dies are easily maintained. By the structural design of the porous plate, the product quality is stable, and the processing efficiency is high.
