一、提升臂零件的压铸工艺适应性分析 1985年3月,我厂接受咸阳纺织机械厂委托,生产锌合金“提升臂”压铸件。图1是提升臂零件简图。从图1可以看出,提升臂四周是不规则外形的板状结构。它的结构设 First, enhance the arm parts of the die-casting process adaptability 1985 年 3 月, I plant to accept Xianyang Textile Machinery Factory commissioned to produce zinc alloy “lift arm” die-casting. Figure 1 is a simplified diagram of the lifting arm. As can be seen from Figure 1, the lifting arm around the irregular shape of the plate-shaped structure. Its structure is set
