毛坯铸件型腔压力检测装置

Pressure Detection Device for Cavity of Rough casting

铸造行业内对一些有腔体结构的铸件,通常在精加工后再进行腔体压力检测,如果腔体有渗漏缺陷而报废,会造成精加工成本的浪费,本论文仅针对腔体为两端开口,且两端开口面正对,但上下开口面不平行,或者铸件腔体为通孔,且其中一端开口孔为小台面的铸件设计一套压力检测装置,实现了铸件在毛坯状态下的型腔压力检测,避免了因为型腔渗漏造成的精加工成本浪费。

In foundry industry, the cavity pressure test of castings with cavity structure often are carried out after finish machining. The castings with the leakage defect are rejected, which may make the waste of the finishing cost. Aimed at the casting with the openings on both ends, moreover both the opening surface are directly faced, the top and bottom surface is not parallel or the casting cavity is opening, and one of it has small surface, the pressure testing device was developed to test the cavity pressure in workblank state, without the finishing cost waste caused by the cavity leakage.
