因旧式滚花刀有些缺点:如采用滑动轴承,滚花轮内孔与芯轴摩损严重;滚花轮的线速度不能太高(最高不可超过8m/min);而且一次完成全深度大网纹滚压时,滚花轮与芯轴容易卡死,如停车不及时,易使滚花刀连同工件一起报废。为此,我们设计制作了一种高速滚花刀,其结构原理如图所示;滚花轮左右两端车有钢球滚道,轴承内圈设计成左右两半,以利装配、维修及调整。为使滚花轮便于切入,减少轴承负荷,把滚花轮外圆的两
Because of the old knurled knives some shortcomings: such as the use of sliding bearings, knurled wheel bore and mandrel serious wear and tear; knurled wheel line speed can not be too high (up to 8m / min); and a full-depth network Grain rolling, knurled wheel and the mandrel easily stuck, such as parking is not timely, easy to knurling knives together with the scrapped. To this end, we designed and manufactured a high-speed knurled knurl, the principle of its structure as shown; knurled round left and right ends of the car has a ball raceway, bearing inner ring designed to about half, to facilitate assembly, maintenance and Adjustment. In order to facilitate knurled cut into the wheel, reducing the bearing load, the knurled wheel outer two
