本刊第三卷第三期,曾载滚丝板齿纹的铣制一文。我厂也经常制造滚丝板,加工方法不同,兹述于后,以供同志们的研究:滚丝板的形状和材料滚丝板的形状如[图一]所示,其宽度随所滚之螺丝长度决定之;长度(图上为155,3/8时螺丝用)则照螺丝直径决定,即螺纹粗的滚丝板要长。因为滚轧螺丝时,螺丝的材料有弹性,轧出之螺纹角度要此滚丝板齿纹的角度略大;所以滚85°螺纹(威氏螺丝)时,滚丝板的齿纹应为53.5°—54.5°;
The third volume of the third issue, was contained in a milling thread rolling pattern. Our factory also often manufacture rolling plate, processing methods are different, are described later, for comrades to study: the shape and material of the rolling plate shape of the plate as shown in [Figure 1], the width of the roll with the The length of the screw is determined; the length (155, 3/8 for the screw in the figure) is determined by the diameter of the screw, that is, the thread of the thick wire is long. Because when rolling the screw, the material of the screw is elastic, and the angle of screwing out is slightly larger than that of the gear of the rolling plate. Therefore, when 85 ° thread (Wittmann screw) is rolled, the tooth profile of the rolling plate should be 53.5 ° -54.5 °;
