自19-82年始,我厂在剖析意大利拉丝模的基础上,对拉丝模的材质和几何尺寸进行了研究,通过三年多的研制工作,取得了一定的效果,特别是同株洲硬质合金厂紧密配合后,研制工作有所突破,新材质,新几何尺寸拉丝模(以下简称为新型拉丝模)的平均使用寿命已经超过 YG 8型拉丝模一倍以上,为高速拉丝创造了条件。根据 IS01684—1975(E)拉丝模规 Since the beginning of 19-82, our factory has studied the material and geometrical dimensions of the drawing die on the basis of analyzing the drawing die in Italy. After more than three years of research and development work, we have achieved certain results. In particular, with the Zhuzhou Cemented Carbide After the close cooperation with the factory, the research and development work has made a breakthrough. The average service life of the new material and new geometry drawing die (hereinafter referred to as the new drawing die) has more than double the YG 8 drawing die, which has created the conditions for high-speed drawing. According to IS01684-1975 (E) drawing die rules
