大批量生产梯形螺杆时,常采用滚压的方法加工,用滚丝轮滚压零件,而滚丝轮是用滚丝柱滚压而成的,滚丝柱是制造滚丝轮的关键工具。滚丝柱分为粗、精滚丝柱,一般成组使用.当用粗滚丝柱滚压滚丝轮时,齿型被滚压出全齿高的三分之二,再换精滚丝柱滚压,当齿顶被滚压得很光滑时,齿型全部成型。在滚压时由于金属塑性变形齿顶会出现未合起的缝隙或齿顶出现凸起,可磨削滚丝轮的外径后再用精滚丝柱滚压成型,此时滚丝轮外径需留有磨量。
High-volume production of trapezoidal screw, often using the rolling method of processing, with rolling wheel rolling parts, and rolling wheel rolling roller is made of rolling, rolling column is the key tool for manufacturing rolling wheel. Rolling column is divided into coarse, fine Rolling column, generally used in groups .When rolling roller with thick rolling column roller, the tooth is rolled out of the whole tooth high two-thirds, Column rolling, when the top of the tooth is rolled very smooth, the tooth shape all formed. In the rolling due to plastic deformation of the metal addendum there will be no joint crevice or addendum appear raised, can be grinding roller diameter and then use the fine roller roller rolling forming, then outside the roller Diameter need to leave a grinding.
