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 a parallel flow evaporator of an automobile air conditioner. The first to fifth stations are arranged on it, and the material strip passes through the first to fifth stations to form a porous plate. Finished product; the first station, which is equipped with 1# mold for punching and piercing; the second station, which is equipped with 2# mold; the third station, which is equipped with 3# mold; the fourth The station has a 4# mold on it; the fifth station has a 5# mold and a 6# mold for cutting to length. The upper die of the 1#-6# die constitutes the upper die for stamping of the progressive die, and the lower die of the die 1#-6# constitutes the lower die for stamping of the progressive die. The purpose of the present invention is to ensure product diversification, reduce mold input costs, make product part switching efficient, fast, and error-proof, molds are easy to maintain, and the porous plate structure design makes product quality stable and processing efficiency high.
