滚压螺纹是在专用滚丝机上,利用冷态压力加工的方法形成螺纹。它是一种高效率的螺纹加工工艺。螺纹光洁度和精度高。因未切断金属纤维故螺纹的强度高,滚丝轮的寿命可高达45万次以上。我厂采取的是径向进给,它的工作过程是:两滚丝轮作同向等速旋转,其中一轮匀速径向压入工件,工件随支架压入另一滚丝轮,三者同向旋转,当滚至要求的尺寸后,进给轮径向移开,支架摆至空档位置,卸下工件。
Rolling thread is a special thread rolling machine, the use of cold pressure processing method of forming threads. It is a highly efficient threading process. Thread finish and high precision. Because of the metal thread is not cut off the thread of high strength, rolling wheel life of up to 450,000 times. I take the factory is radial feed, and its working process is: two rollers for the same direction to rotate at the same speed, one of the uniform radial pressure into the workpiece, the workpiece with the stent into the other rolling wheel, the three with Rotate, roll to the required size, the feed wheel radially removed, the stent swing to neutral position, remove the workpiece.
