我厂的大量标准件生产中,冷镦件的外螺纹均采用搓丝机或液压滚丝机进行自动或半自动滚压方法。但在单轴、多轴自动车床或六角普通车床上加工螺纹另件,由于缺乏通常的螺纹套丝头或螺纹滚压头,螺纹工序不能集中在一台机床上完成。这样既不能充分发挥机床的效能,同时往往保证不了另件尺寸的精度要求。我厂在参考国内外有关技术资料的基础上,设计制造了外螺纹切向滚压装置。经一年多来成批生产各种外螺纹标准件(直通管接头,螺 I plant a large number of standard parts production, cold heading pieces of the external thread are used thread rolling machine or hydraulic rolling machine for automatic or semi-automatic rolling method. However, in the single-axis, multi-axis automatic lathe or hexagonal lathe machining parts, due to the lack of the usual thread trocar or thread rolling head, the thread can not focus on a machine to complete. This can not give full play to the effectiveness of machine tools, often can not guarantee the accuracy of the size of the other pieces of the request. I plant in reference to the relevant technical information at home and abroad on the basis of design and manufacture of the external thread tangential rolling device. After more than a year to mass production of various male standard parts (straight pipe fittings, screws
