冲孔工作是冲压中主要工序之一,一般情况全采用手工送料和出料,因此效率很低,并且很不安全。在党提出向机械化,自动化进军的号召后,老工友宋永科提出了将垫圈冲孔改成自动化操作的建议。经过几天的苦战,在技术人员的密切配合下,终于试验成功冲孔的单机自动化。其送料机构如图1。将欲打孔的零件,放于用半马力电机带动的圆盘1中。由于圆盘呈倾斜形,故在转动 Punching work is one of the main processes in stamping, the general situation of using manual feeding and discharging, so the efficiency is very low, and very unsafe. After the party put forward the call for mechanization and automation, the old coworker Song Yongke put forward the suggestion of changing washer punching into automatic operation. After a few days of hard work, in close cooperation with technical staff, finally successful single-hole punching test automation. The feeding mechanism shown in Figure 1. Place the part to be punched into the disc 1 driven by a half-hp motor. As the disc was inclined shape, so the rotation
