我厂船用压缩机连杆锻件(图1)是在400公斤空气锤上自由锻制坯,其制坯过程如图2。在制坯时,要考虑在制坯时,要考虑,终锻成型过程中材料的均匀分配和流动。因此首先将料拔成63 x 63毫米的带斜度的方形,然 I plant ship compressor connecting rod forgings (Figure 1) is free forging on the air hammer in the 400 kg billet, the billet process shown in Figure 2. In the billet, it is necessary to consider in the billet, we must consider the final forging process of uniform distribution and flow of materials. So first of all the material will be drawn into a 63 x 63 mm square with a slope, of course
