零件在切削加工后留下微细的痕迹,经滚、挤后可以得到较细的表面粗糙度和提高表面硬度,确保质量并延长油缸和皮碗的寿命。具体做法,介绍如下。一、结构原理滚挤压头的结构。首先把调整套2拧在心轴1上,装弹簧3、斜轮5(材质为45钢,HRC45～50)。然后把三个滚珠7均布在斜轮5的中间,在铜套6上均匀钻三个小于滚珠7直径的孔。用于滚珠在铜套6和斜轮5之间的定位,滚珠在铜套6内不能出来就可以了。铜套6和斜轮5间隙为0.2～0.3
Parts left in the machining traces of fine, after rolling, squeezing can get a finer surface roughness and improve the surface hardness, to ensure quality and extend the life of the cylinder and leather bowls. Specific practices, introduced below. First, the principle of structure Rolling head structure. First, adjust the sleeve 2 on the mandrel 1, install the spring 3, inclined wheel 5 (made of 45 steel, HRC45 ~ 50). Then three balls 7 are evenly distributed in the middle of the bevel gear 5, the copper sleeve 6 evenly drilled three holes smaller than the diameter of the ball 7. For ball positioning between the copper sleeve 6 and the bevel gear 5, the ball can not come out in the copper sleeve 6. Copper sleeve 6 and the inclined wheel 5 clearance of 0.2 ~ 0.3
