本文介绍一种特殊的橡胶拉延模,压制仪器上用的反光碗。用钢模加工这种零件要经过下料、拉深、成形、校形等四道工序,工序间还要退火处理,零件质量不易保证。采用橡胶压延模,只需下料、成形两道工序,零件质量显著提高。 This article describes a special rubber drawing die, pressing the instrument used on the reflective bowl. Steel mold processing of such parts to go through the blanking, drawing, forming, calibration and other four procedures, but also between the annealing process, the quality of parts is not easy to guarantee. The use of rubber calendering die, just blanking, forming two processes, parts quality significantly improved.
