我厂产品零件中溥壁管零件占有很大的比重。管子(储油筒)两端有螺距为1.5mm、长度10～12mm的螺纹,原用车削工艺加工。以400cm~3储油筒为例,车削螺纹,管材外径50mm、壁厚不小于1.5mm的无缝钢管,班产定额150件,钢材消耗大,生产效率低。为此我们开始了薄壁管滚丝工艺的研究,用外径50mm、壁厚1mm 的无缝管代替φ50×1.5的无缝管,用滚丝工艺代替车削工艺。经过近一年
Pu factory pipe fittings in our products parts occupy a large proportion. Pipe (reservoir) at both ends of a pitch of 1.5mm, length of 10 ~ 12mm thread, the original turning process. To 400cm ~ 3 storage cylinder, for example, turning thread, the pipe diameter 50mm, wall thickness of not less than 1.5mm seamless steel pipe, tube production quota 150, steel consumption, low production efficiency. To this end, we started the research of thin-walled tube rolling technology, with a diameter of 50mm, 1mm thick seamless tube instead of φ50 × 1.5 seamless tube, thread rolling process instead of turning process.
