过去我厂在搬运扁形金属料或铸绽料的时候,是采用苏联造的铸锭夹钳来工作的。它是手动的,不但笨重和不易控制,而且由于控制钳口张开度的撑杆强度差,经常弯曲和折断,影响生产。后来我厂一工人同志设计出一台新型夹钳,试用数月,效果良好,现已正式投入生产。现将新型自动夹钳的工作状况及示意图介绍如下: In the past when I moved the flat metal or cast material, I used the ingot clamp made in the Soviet Union to work. It is manual, not only bulky and difficult to control, but also because of the poor strength of the struts that control the opening of the jaws, often bending and breaking, affecting production. Later, I plant a worker comrade to design a new type of clamp, try for several months, the effect is good, is now officially put into production. Now the new automatic clamp working conditions and schematic introduction is as follows:
