一、前言螺紋滚压扳牙是一种新型的螺紋加工工具,經过苏联某些工厂的长期研究,已将这种工具改进成为較完善的結构。我国早在1954年,萧福利同志也曾創造了一种提高螺紋加工生产效率的新工具——擂絲刀,将螺紋的生产效率提高8～10倍。經驗証明:采用滚压代替車削来加工螺紋,不仅工作效率大大提高,而且产品貭量也得到极大改善。在研究螺紋滚压板牙的同时,必須对以下两个問題加以分析: (1)怎样保証被滚压螺紋的精度; (2)滚压扳牙的实用价值及經济效果。
I. INTRODUCTION Threaded rolling jaws are a new type of thread processing tool. After long-term research in some factories in the Soviet Union, this tool has been improved into a more perfect structure. As early as 1954 in our country, Comrade Xiao Fuli also created a new tool to improve the production efficiency of thread processing - the wire cutter, which improved the production efficiency of the thread by 8 to 10 times. Experience has proved that: the use of rolling instead of turning to the processing of threads, not only greatly improve work efficiency, and product quality has also been greatly improved. In the study of thread rolling teeth at the same time, we must analyze the following two issues: (1) how to ensure the accuracy of the thread being rolled; (2) the practical value and economic effect of rolling the tooth.
