本文阐明了热模锻润滑剂的研究方法和在各种工艺润滑的生产条件下试验模锻件的某些数据。所提出的方法的实质是在锥形模内闭式镦粗园柱形试样(图1)。将所研究的润滑剂涂在模具的锥形表面上,而后放上园柱形试样进行镦粗,试样的体积应当与模膛的体积一致。当从模内顶出被镦粗的试样 This article illustrates the research methods for hot-forging lubricants and some of the data for testing forgings under various process lubrication conditions. The essence of the proposed method is to upset the cylindrical specimen in a conical mold (Figure 1). Apply the lubricant of interest to the conical surface of the mold, then place a cylindrical specimen for upsetting. The volume of the specimen should be the same as that of the mold cavity. When the sample is upset from the mold upset
