目前电脉冲加工主要是解决锻模的型腔加工问题,很少用于切割;特别是大面积切割,更很少有人(口尝)试。最近济南汽车制造总厂曾用D5570型电脉冲机床,对730×420×300(长×宽×高)毫米的模块进行切割,其效果较好。体现如下几点: 1、用这种方法切割时,切缝较小,一般在2～5毫米范围之内.这样就可以使730×420×300毫米的大模块切成350×400×275毫米两个小模块.而如果用气焊切割,其切缝较大,而且不适于切割。 2.用电脉冲切割时,切割面的热影响极小,对金属内部几乎无影响,基本上可保证材料的性能不变。
At present, electric pulse processing is mainly used to solve the problem of cavity processing of forging dies, and is rarely used for cutting; in particular, large-area cutting, and few people (mouth-testing) try. Recently, the Jinan Automobile Manufacturing Plant had used the D5570 type electric pulse machine to cut 730×420×300 (length×width×height) millimeter modules, and its effect was good. The following points are reflected: 1. When this method is used for cutting, the slits are small, generally within the range of 2 to 5 mm. This allows large modules of 730×420×300 mm to be cut into 350×400×275 mm. Two small modules. If you cut with gas welding, the kerf is larger and not suitable for cutting. 2. When cutting with the electric pulse, the heat affected by the cutting surface is extremely small, almost no influence on the interior of the metal, and the performance of the material can be basically ensured.
