根据国内外冷挤压实验资料,探求各种不同冷挤压方式下单位挤压力间的相互关系,提出了互相换算的经验公式,应用这一公式可以大大减少实测材料冷挤单位压力的试验工作量。本文应用此公式建立了我国常用冷挤压钢材(九种)空心件正挤压的p—ε_F曲线,并补充了我国纯铁反挤压的p—ε_F曲线。 Based on the data of cold extrusion experiment both at home and abroad, the relationship between unit extrusion pressure under different cold extrusion methods is explored, and the experiential formula of mutual conversion is put forward. By applying this formula, the test of cold extrusion unit pressure can be greatly reduced Workload. In this paper, the p-ε_F curve of normal cold extrusion steel (nine kinds) hollow parts is established by this formula, and the p-ε_F curve of pure iron counter-extrusion in our country is supplemented.
