在科学技术不断发展和市场竞争激烈的情况下,为赢得时间,尽快推出新产品,以提高企业的经济效益,其主要措施之一是简化模具结构,缩短模具制造周期和降低模具制造成本。由于聚氨酯橡胶冲裁模具相对于钢模来说简化了模具结构,降低了模具的制造精度(特别冲薄料),且具有比钢模更佳的综合机械性能和加工性能,因而在近十年中有了较大的发展。我厂二十六种不同类型和规格的薄垫圈,均采用聚氨酯橡胶冲模加工。图1所示为部分
In the continuous development of science and technology and the fierce market competition, in order to win the time and launch new products as soon as possible so as to enhance the economic efficiency of enterprises, one of the major measures is to simplify the structure of the mold, shorten the mold manufacturing cycle and reduce the cost of mold manufacturing. Since polyurethane rubber blanking die simplifies the die structure relative to the steel die, reducing the manufacturing precision of the die (especially the thin material) and has better mechanical and processing properties than the steel die, In the larger development. I plant twenty-six different types and specifications of thin washers, are made of polyurethane rubber stamping process. Figure 1 shows the part
