本文叙述了PQJ-01喷砂切割机的设计原理和应用,着重论述了研制过程中几个主要技术关键问题的解决方法。 PQJ-01喷砂切割机是利用具有一定压力的压缩空气喷射高速金刚砂流,对薄、硬、脆性材料零件直接击穿并切割成形加工的新型工艺设备。它用于摆片的中心孔和圆弧槽的成形加工,从而为摆片的加工制造开辟了新的技术途径。试验表明,该机对一些难加工材料,如硬磁合金,微晶玻璃等材料有较好的加工效果。 This paper describes the design principle and application of PQJ-01 sandblasting machine, focusing on the solution to several key technical problems in the development process. PQJ-01 sandblasting cutting machine is the use of a certain pressure of compressed air jet high-speed diamond flow, the thin, hard and brittle material parts directly breakdown and cutting forming processing of new technology equipment. It is used for forming the center hole and the arc groove of the swing piece, thus opening up a new technical way for the manufacture and processing of the swing piece. Tests show that the machine for some difficult to process materials, such as hard magnetic alloy, glass and other materials have better processing results.
