我厂自一九七一年试制成功热轧小钻头以后,由于生产效率的提高,对弯曲检查工序,一直是个关健问题。根据兄弟厂同类型产品的检查方法,都是用一个平台,把钻头放在平台上,用灯光透视方法和用塞尺塞的方法来检查,每天只能检查300～500支,效率很低,工人很费眼睛。针对这个关键,我厂老工人阎宝儒同志和其他工人共同研究,在72年6月份革新成功了小钻头弯曲检查具(如图所示)。用两个平台,中间垫一个垫 Since our trial production of hot rolling small bits in 1971, our factory has always been a key concern for the bending inspection process due to the improvement of production efficiency. According to Brother factory inspection methods of the same type of products, are using a platform, the drill on the platform, with light perspective method and plug the way to check, every day can only check 300 to 500, the efficiency is very low, Workers are very eyes. In response to this key point, Comrade Yan Baoru, an old factory worker, and his other workers studied together and succeeded in innovating a small bit bending test fixture in June of 72 (as shown). With two platforms, the middle pad a pad
