Z148B型造型机由于具有结构简单,操作容易、维修工作量较小等优点,在国内使用比较普遍。我厂共有近30台Z148B型造型机,在几个分厂都起着重要的作用。一、原震击机构 Z148B型造型机原设计的震击机构如图1,其工作原理是:压缩空气进入震击活塞内腔,通过有调节螺钉的进气孔进入震击气缸内,使震击活塞升起,至打开排气孔时,排 Z148B molding machine has the advantages of simple structure, easy operation and small maintenance workload, which is commonly used in China. I plant a total of nearly 30 Z148B-type machine, in several plants all play an important role. First, the original shock mechanism Z148B-type machine The original design of the shock mechanism shown in Figure 1, its working principle is: compressed air into the shock piston cavity, through the adjustment screw into the shock hole into the cylinder, so that earthquake Hit the piston rises, to open the vent, row
