空气锤压制过程的控制

源自:滕州市高地机床有限公司   时间:2019/2/28 14:58:20

 我们都知道空气锤是通过压缩缸压缩空气,通过提拉锤头来完成锻打。我们空气锤它的原材料是怎么形成的呢?我们使用的铸件是通过对粉末体施加一定的压力并保压一定时间,使粉末压缩,得到所要求的具有一定密度和强度的坯料称为压制。由此可见,在压制过程中通过对压力大小、压制行程、压制速度、保压时间等压制参数的合理控制,便可压出合格的粉末压坯。压制压力压力越大,压坯的密度越高。在选定了合适混合料的情况下,使用一定的压力以便获取所要求的压坯密度。在此需要指出的是对于多台阶的压坯一定要测各台阶的分体密度,尽量做到各模充单位压制压力基本相同,否则压力越大圧坯的密度误越大,模具容易损坏。
