介绍了数字雕刻技术在骨架式轴唇圈模具加工中定位凸台、标记符号、数字、以及流体动力型轴唇圈的模具左旋、右旋回油线、具有双向回流作用的“∧”“△”等形式回油线的加工方法,雕刻的回油线具有定位准确,深浅均匀,不会产生错线、不全、重叠等现象,是以往滚压法所不能比拟的,极大地提高了骨架式轴唇圈的质量。 This paper introduced the digital engraving technique to locate boss, mark symbol and number in the processing of skeleton shaft and lip ring mold, as well as the mold left-hand and right-handed oil return line of the fluid power shaft lip ring, with “∧” △ "And other forms of oil return line processing methods, carved oil return line has the positioning accuracy, uniform depth, will not produce misplaced lines, incomplete, overlap and so on, is unmatched by the previous rolling method, which greatly improves the skeleton The quality of shaft lip ring.
