针对中小型机修厂加工品种繁多、批量小的特点,我厂锻工师傅创造了一些在自由锻锤上简锻的模具,这些模具制造简单、使用方便,模具无需用特殊钢材,锻件的切削量很少,及时解决了急需配件、备件的问题。汽车油泵传动轴套管叉(图1)简锻是其中的一种。套管叉简锻是在200公斤空气锤或夹板锤上二火锻成的。第一火预锻(预锻模具见图2),第二火终锻成形(终锻模具见
For small and medium-sized machine repair plant processing a wide variety of features small batch, I plant forge master created a number of free forging hammer on the simple forging mold, the mold manufacturing is simple, easy to use, the mold without special steel, forging cutting amount Few, promptly solved the problem of spare parts, spare parts. Automotive pump drive shaft sleeve fork (Figure 1) Jane forging is one of them. Casing fork forging is 200 kg air hammer or splint hammer forged on the second fire. The first fire pre-forging (pre-forging die shown in Figure 2), the second fire final forging (see forging die
