我厂一台仿苏Z265造型机因震实无力,而无法继续工作。拆卸后发现,震实缸与震实活塞间隙达1.2mm,活塞环已失去密封作用。按常规必须要调换震实缸,但震实缸本身又是压实活塞,外径达630mm,长度为720mm,重量达1t。如要重新制作,周期较长,费用约3000元。经研究决定,把震实缸镗大,用镶套的办法来恢复内径250mm的尺寸。为增强镶套耐磨性,改用QT 42-10材料。如图所示,我们设计了震实缸的镶套,镶套与震实缸采用过渡配合φ270(H8/n7)。把压实活 I plant a imitation Su Z265 molding machine due to the fact that weakness, and can not continue to work. Disassembled and found that shock really shocking cylinder and piston clearance of up to 1.2mm, the piston ring has lost its sealing effect. In fact, it is necessary to exchange the shocking cylinder, but the shocking cylinder itself is a compacting piston with an outer diameter of 630mm, a length of 720mm and a weight of 1t. If you want to re-production, longer cycle costs about 3,000 yuan. After the study decided to shock the actual cylinder boring large, with set of ways to restore the inner diameter of 250mm size. In order to enhance the abrasion resistance of the insert, use QT 42-10 material instead. As shown in the figure, we designed a vibrating cylinder insert with a transition fit φ270 (H8 / n7). Keep compaction alive
