杠杆体坯件冷拔成形工艺及其平直度的研究

Studying on the Cold-drawing Forming Technology and Plane-straight Degree of Lever Base

此文详细介绍了磅称杠杆坯件冷拔成形工艺过程和工艺参数,分析了生产中存在的翘曲、扭曲、旁弯及瓦形等严重形状缺陷的成因,论述了减少形状缺陷、提高平直度的工艺技术措施。

The cold-drawing forming technological process and parameters of platform scale lever base is presented in detail in this paper. This paper analyses how to form the serious form defects,such as curl,twist,sickle curve and cross bow etc. ,existing in preducing,and advances the technological measure of reducing the form defects and improving the plane-straight degree.
