我厂的主要产品是地质钻探机械和钻探工具,产品的特点是批量小、品种多。虽然我厂的模锻、辗扩、挤压及平锻等工艺有了较大的发展,但胎模锻生产仍是主要生产方法之一。现通过一些工艺实例介绍我们在胎模锻技术应用方面的情况和体会。 1.筒形件:一般有两种方法,一种是用圆料冲孔拔长,另一种是直接用钢管生产,由于第二种方法可免去锻坯的制备过程,提高生产效率,所以,如果条件合适应优先考
I plant the main products are geological drilling machinery and drilling tools, the product is characterized by small quantities, more varieties. Although our factory forging, rolling expansion, extrusion and forging and other processes have a greater development, but the production of fetal die forging is still one of the main methods of production. Now through some examples of technology introduced in the application of fetal die forging technology and experience. 1. Cylinder: There are generally two ways, one is the round with a long hole punching, and the other is the direct use of steel pipe production, the second method can be removed from the preparation process of forging billet to improve production efficiency, Therefore, if the conditions are appropriate should be given priority
