在许多锻压车间(如水压机车间)里,锻压钢锭时应用套筒。用吊在行车上的翻料机链帮助抬起或安放套筒,但是化在这上的时间很多,并且要占用1～2个辅助工人。为了节省生产中的辅助时间和人力,可采用一种专门的装置(见图)。地脚螺1用水泥固定在坑内,地脚螺、坑、支垫块的尺寸照套筒的大小尺寸来撰定。图上所给的尺寸是套18吨钢锭的套筒。取用时把翻料机链子套在套筒2的尾部支垫块处 In many forging shops (such as hydraulic press shop), forging steel ingot sleeve. Use the hoist chain hanging on the car to help lift or place the sleeve, but this time spent a lot, and to take up 1-2 auxiliary workers. In order to save time and manpower in production, a special device can be used (see figure). Toe snail 1 fixed with cement in the pit, toe snail, pit, pad size according to the size of the sleeve to be written. The size given on the chart is the sleeve of a 18 ton ingot. When taking the tucker chain cover sleeve sleeve 2 at the end of the pad
