在锻六方条时,一般用一块厚度等于六方对边的垫铁放在下砧上进行锻造,或用一个六方下胎。我们使用了如图1的六方条锻模,它的结构简单,使用方便,可以省一个工人。图中1是六方下胎,其详细尺寸见图2及附表,2是左、右支板,3是固定在框架4上的转轴,5是固定螺丝,6是旋紧螺丝防止框架与下砧发生相对运动,可以 In forging six square bar, generally with a thickness equal to six on the side of the horn on the anvil on the forging, or with a six-under-tire. We use the hexagonal bar forging as shown in Figure 1, which is simple in structure and easy to use, saving a worker. 1 is a hexagonal undercarriage, the detailed dimensions shown in Figure 2 and Schedule, 2 is the left and right struts, 3 is fixed on the frame 4 of the shaft, 5 is a fixed screw, 6 is to tighten the screw to prevent the frame and under Anvil relative movement, you can
