In order to improve the workabilities of raw materials. . and the mechanical properties of products in metal forming processes at warm temperatures, a new thermomechanical treatment named Warm Temper Forging Method, which was developed by the authors, has to be applied for some industrial processes and for this purpose, a new warm former which has various abilities and kinetics has to be developed. In this project, a prototype machine of warm former was constructed and some experiments on deep drawing in warm temperature regions. were conducted for many kinds of steel sheets. The following results were obtained :(1) A new machine was developed by improving an oil pressure press of 30 tonf combined with a newly developed electrical and oil-preesure survo. mechanics. As a result, the ram speed can be controlled exactly by a computer programming.(2) A new experimental device for warm deep drawing. was constructed and many kinds of experiment were conducted.(3) An electrical direct heating method was developed.(4) Anisotorppy of steel sheet was investigated using a partial heating method, and a new warm forming process was investigated and developed.

以提高原料的加工性。。为了提高金属成形过程中产品在温热条件下的力学性能，必须将作者提出的一种新的形变热处理方法--温回火锻造方法应用于某些工业过程，为此，必须开发一种具有多种性能和动力学的新型温成型机。本课题研制了温成型机样机，并在温区进行了拉深实验。对多种钢板进行了热加工试验。结果表明：(1)通过对30tf油压机的改进，结合新研制的电压机和油压机，研制出一种新型压力机。机械师。因此，可以通过计算机编程精确控制冲压速度。(2)一种新型的温拉深实验装置。(3)开发了一种电直接加热方法。(4)采用部分加热法研究了钢板的各向异性，研究并开发了一种新的温热成形工艺。
