高压开关屏蔽罩普旋成形工艺的研究

Research on the common spin-forming technique for the shielding case of high voltage switchgear

通过对毛坯尺寸确定、模板设计、旋压参数选择、旋压机床等等几方面对屏蔽罩零件的普旋成形工艺进行讨论; 结合旋压成形试验过程, 制定出较理想的工艺方案, 试验验证该工艺完全适应屏蔽罩零件的成形加工,可作为旋压类似产品成形加工的参考。

A common spin-forming technique for the shielding case has been discussed, considering the determination of blank, the design of model plate, the choice of spinning parameter and the spinning machine. A more ideal technique method has been brought out through spin-forming experiments, which confirms that common spin-forming technique is applicable to formative processing for the parts of the high voltage switchgear products. This can be a reference for the similar products to be formatively processed by spin-forming
