随着飞机、汽车、拖拉机,涡轮机制造业的发展,尤其是以宇宙空间的开发为背景、难加工的材料,难加工的形状日益增多,这就给各种特种加工工艺主法特别是“电解加工”带来了课题。大功率,低电压,大电流可控硅调压的硅整流直流电源的问世,给提高电解加工的生产率,扩大电解加工的应用范围提供了可能。特别是近十年来,由于电解加工机床和工具电板的设计与制造日趋完善“间隙理论”和电解液的深入研究,适应控制和实际的差距不断的缩小以及为了提高电解加工的精度在工艺上采取了多种有效的措施,使得电解加工朝看高效率,高精度方向发展,并正以着日新月异的速度向前迈进。在我厂电解加工的各种涡轮机叶片中,34#汽轮机第一根整体双联动叶片就是一例。
With the development of the aircraft, automobile, tractor and turbine manufacturing industries, especially in the development of cosmic space, the increasing number of difficult-to-machine materials and difficult-to-process shapes give rise to a variety of special processes, Processing “has brought the issue. The advent of high-power, low-voltage, high-current SCR silicon rectifier DC power supply to improve the productivity of electrolytic processing, expanding the scope of application of electrolytic machining possible. Especially in the past ten years, due to the increasingly perfect design and manufacture of EDM and tooling plates, ”gap theory" and in-depth study of electrolyte solution, the control gap between actual control and actual shrinking has been gradually narrowed and in order to improve the precision of electrolytic machining, Take a variety of effective measures to make electrolytic processing toward the direction of high efficiency and high precision, and is moving at a rapidly changing speed. Among the various turbine blades electrolytically processed in our factory, the first overall double-linkage blade of 34 # steam turbine is an example.
