图1所示为滚轮式内孔滚压工具,适用于直径为30～60毫米,长度在150毫米以内的内孔。滚轮3直接对零件进行滚压。为了提高滚动效果,减少滚轮内孔和芯轴的单向磨损, 在滚轮和芯轴间装以滚针,并采用内孔供油润滑。由于滚轮和零件内孔接触面积较大,所以,滚压力需要增大。滚压后零件的光洁度和滚轮的光洁度有关。一般可达▽8以上。 Figure 1 shows a roller-in-hole rolling tool for internal holes 30 to 60 mm in diameter and 150 mm in length. Rollers 3 roll parts directly. In order to improve the rolling effect, to reduce the unidirectional wear of the roller bore and mandrel, roller and mandrel installed between the needle roller, and the use of oil lubrication hole. As the roller and parts within the hole contact area is larger, so the rolling pressure needs to be increased. After rolling parts of the finish and wheel finish. Generally up to ▽ 8 or more.
