制造薄壁螺纹,尤其是壁厚小于l毫米时,采用切削方法是困难的,若采用滚轧方法加工就较为容易。为了便于小批量加工某些特殊规格的薄壁螺纹件,我厂设计制造了一种手动滚轧薄壁螺纹的夹具。图1是薄壁螺纹件,其材料为黄铜H 68,壁厚 Manufacture of thin-walled threads, especially wall thickness less than 1 mm, the use of cutting method is difficult, if the use of rolling method is easier. In order to facilitate the processing of small quantities of some special specifications of the thin-walled screws, I design and manufacture of a hand-rolled thin-walled thread fixture. Figure 1 is a thin-walled screw, the material is brass H 68, wall thickness
