原来情况:在冲床上冲孔,要先用样板划线,打好洋冲眼,再按划线标記冲孔。因为每天冲孔的数量很多,冲眼时用眼睛找准很吃力,質量也无法保证,又不能进一步提高生产效率。改进情况:李順度、姚伯兴两位老师傅在革新运动中,經过两个多月的試驗,用一些簡单的零件,制成一付冲孔用的自动定位架。把它装在冲床旁边,只要按工件各孔间的距离預先調整好定位柱,就能取消以上两道工序,冲孔的效率和质量都有提高。附图是自动定位架的结构和工作过程图。1是前部經折断后的工件安放情况;2是縱向定位靠钣;3是槽形定位架;4是横向活动定位柱;5是細圓弹簧;6是
The original situation: Punching in the punch, we must first scribe the model, lay Yang Chong eyes, punctuated by marking under punctuation. Because a large number of punching every day, punching the eye with a very accurate look, the quality can not be guaranteed, they can not further improve production efficiency. Improvement: Lee Shun-degree, Yao Bo-hing Two old masters in the reform movement, after more than two months of testing, with some simple parts, made of a pair of punching with automatic positioning frame. Put it in the punch next to the workpiece as long as the distance between the holes pre-adjust the positioning of the column, you can cancel the above two processes, punching the efficiency and quality have improved. Figure is the automatic positioning rack structure and working process. 1 is the front of the workpiece after the breakage situation; 2 is longitudinally positioned by the sheet; 3 is a slot-shaped positioning frame; 4 is a horizontal positioning column activities; 5 is a thin round spring; 6 is
