在国内,常见的冷轧外螺纹加工方法多是采用环形滚轮和螺纹滚压头两种比较成熟的形式。采用这两种形式,工件的中径尺寸、螺纹升角及齿形要求均受到滚压装置的限制。针对这样的情况,我们参考了国内外有关螺纹滚压的专门资料,经过验证,成功地设计出了一种新型的滚轮,轧出了符合设计要求的丝杠试样,从而为解决以往加工中常见的问题提供了办法。一、设计原理新的滚轮设计思想是结合了两种常见的滚轮设计方法而形成的。一种是径向螺纹滚轮;另一种是环形滚轮。前者具有加工简单、加工精度高、使用寿命长的特点;后者通过扳过一定的角度,使工件在加工时产生轴向运动。我们在新的设计中吸收了这两者的优
In China, the common cold-rolled external thread processing methods are mostly used ring roller and thread rolling head two more mature forms. Adopting these two forms, the diameter of the workpiece, the angle of the thread and the tooth profile are all limited by the rolling device. In view of this situation, we refer to the domestic and international information on the thread rolling specializes in the verification, successfully designed a new type of roller, rolled out the screw test samples meet the design requirements, so as to solve the previous processing Common problems provide a solution. First, the design principle The new wheel design idea is a combination of two common wheel design methods and formed. One is a radial thread roller; the other is a ring roller. The former has a simple processing, high precision, long life characteristics; the latter by pulling a certain angle, so that the workpiece in the processing of axial movement. We have absorbed the advantages of both in the new design
