工具体5的尾方(附图)压置在方刀架上。与尾方侧面垂直的孔和滑套4的外圆滑配合。在单列向心球轴承6内穿入销轴7,垫上定位套8,以螺纹紧固在滑套4上。这样单列向心球轴承以滚动摩擦方式,在工具体5的T型槽中与滑套4同时轴向移动,并控制了滑套4的转动。板牙1装在支承套3的孔中,用顶丝2紧固。支承套3装在滑套4的孔中,用顶丝紧固。支承套3的孔是根据不同规格板牙具体尺寸制造的。
The tail of the tool body 5 (drawing) is pressed against the square knife holder. The hole perpendicular to the tail side and the outer circle of the sliding sleeve 4 are matched with each other. In the single row of radial ball bearings 6 penetrate the pin 7, the pad positioning sleeve 8, to the threaded fastening sleeve 4. Such a single row of radial ball bearings in a rolling friction mode, the T-shaped tool body 5 with the sleeve 4 while moving axially and controlling the rotation of the sleeve 4. Die 1 mounted in the hole in the support sleeve 3, with top wire 2 fastening. Support sleeve 3 installed in the hole in the sleeve 4, with top wire fastening. The hole of the supporting sleeve 3 is made according to the specific dimensions of the die of different specifications.
