电机械熨压工艺,足一种既能提高零件表面的光洁度,又能使零件表面淬火强化的新技术。被加工零件的材料要具有导电性能。熨压装置如图所示。旋转零件1装夹在车床夹盘上。硬质合金熨压块2装在支架3上,并沿零件表面移动。熨压开始前接通电源装置4;熨压完成后,将其断开。熨平原理:当电流通过熨压块和零件表面接触点时、产生了热量,使零件表面层加热到高于临界温度20～50℃。然后,由周围的空气把零件表面的热量迅速带走,从而使零件表面层实现表面淬火处理。除此
Electromechanical pressing process, enough to both improve the surface finish of the part, but also to make the surface hardening of the new technology. Materials to be processed parts to have conductive properties. Ironing device as shown. The rotating part 1 is mounted on the lathe chuck. Carbide compacts 2 mounted on the bracket 3, and along the part surface. Switch on the power supply unit 4 before ironing starts; turn it off after ironing is complete. Ironing principle: When the current through the pressing block and parts surface contact point, the heat generated, the parts surface layer heated above the critical temperature of 20 ~ 50 ℃. Then, the surrounding air rapidly removes the heat from the surface of the part, so that the part surface layer is surface-hardened. Except this
