众所周知,链轮齿的加工是制造链轮最复杂的工序.在曲柄压力机上目前用阴模已可把链轮的齿在1～2次行程中冲制而成.但这样获得的链轮在其端面上常常会产生毛刺,而在齿的侧面上则有小缺口和划痕.苏联哈尔科夫学院新近研制成一种采用平丝板冷滚压链轮齿的新方法.滚压前应先估算滚压毛坯的原始尺寸(见附图右),然后再 As we all know, sprocket tooth sprocket processing is the most complex process of manufacturing sprocket. In the crank press on the current use of the female sprocket has the sprocket teeth in 1 to 2 punches made, but the sprocket so obtained Burrs often occur on the end faces and small indentations and scratches on the sides of the teeth.Khalkhov Institute of the Soviet Union has recently developed a new method of cold rolling sprocket with flat wire mesh First estimate the original size of the roll blank (see the picture to the right) and then again
