74年下半年该厂磨圆锥滚子双端面的工序实现了自动送料。为了提高送料速度,他们重点改进了送料盘的结构。改进后的送料盘有两种型式,一种适用于磨削长度较大的滚子,另一种适用于磨削短小的滚子,使用于生产后均收到了良好的效果,如以7204型轴承为例,料套的数量比使用旧式送料盘时增加了114.3％,料套所耗用的材料比改进前节约72.7％,单个料套的加工工时比改进前减少0.23小时,生产效率比改进前提高1～1.5倍,而且加工质量没有明显的降低,完全可以达到软磨双端面工序规定的质量指标。
The second half of the 74 factory taper roller double-sided process to achieve automatic feeding. In order to improve the feeding speed, they focus on improving the structure of the feeding tray. There are two types of the improved feeder, one is suitable for grinding longer roller length and the other one is suitable for grinding short roller. After being used in production, it has received good effect. For example, 7204 For example, the number of bushing is increased by 114.3% compared with that of the old feeding disc, the material consumed by the bushing is saved by 72.7% compared with that of the former, the working time of a single bushing is reduced by 0.23 hours compared with that before, Improve 1 ~ 1.5 times before, and there is no obvious reduction of processing quality, which can fully meet the quality standard stipulated in the soft grinding double-end process.
