在电器行业和仪器仪表行业中,硅钢片冲模占有相当大的比重,且倒装结构的复合模被广泛采用,但对于漏料的锥孔,因大多数中小型厂缺乏锥孔磨削设备,要达到规定的技术要求是比较困难的。 我厂模具车间在生产实践中,试制的斜度小于25′的锥度铰刀,解决了锥孔的精加 In the electrical industry and instrumentation industry, silicon steel sheet dies occupy a large proportion, and flip-chip composite molds are widely used, but for taper hole leakage, because most small and medium-sized factories lack of cone grinding equipment, To achieve the required technical requirements is more difficult. I die factory workshop in the production practice, the trial of the taper of less than 25 ’taper reamer, to solve the cone of precision
