下面介绍一种脉冲滚压工具,用以加工普通铝合金材料,光洁度可达▽7以上。脉冲滚压工具(如图1)以导套导入被滚压的孔中,靠孔自动定心,因而滚压工具可以做成浮动连接,或者工件浮动,以达到孔自动定心的目的。三对滚针安放在滚针保持器内,并能自由滚动。同时,滚针保持器对刀杆能自由地相对转动。装配时要使滚针保持器与滚针长度相配合。钢球用来承受滚压时的轴向力。为使钢球能自由滚动,可修磨磷青铜垫圈,使轴向间隙在0.1～0.15mm以内。
The following describes a pulse rolling tool for processing ordinary aluminum alloy, finish up to ▽ 7 or more. The pulse rolling tool (see Figure 1) is introduced into the rolled hole by the guide sleeve, and the center of the hole is self-centering. Therefore, the rolling tool can be made into a floating connection or the workpiece can float to achieve the purpose of automatic centering of the hole. Three pairs of needle placed in the needle holder, and can freely scroll. At the same time, the needle holder can freely rotate relative to the cutter bar. Need to make needle roller holder and needle length matching. Ball used to withstand the axial force rolling. In order to make the ball can roll freely, can repair the phosphor bronze washer, so that the axial clearance within 0.1 ~ 0.15mm.
