断丝和抖丝都是线切割操作工和维修人员头痛的事。一般采用管式和开合式供给工作液,断丝的现象尤为明显,其原因是工作液不能均衡达到加工部位和漏液,电极丝受到的冲击力不均匀,加之工作液本身是一个脉冲振荡源,故在其运动过程中,随着受力的变化便产生较强振动(即抖丝),严重时即引起断丝。我们在DK7730B型线切割机床上,用了漏流隔喷法供给工作液,成功地对该设备进行了改进。如图所示,当工作液进入给水
Broken wire and shaking wire are the headache of wire cutting operators and maintenance staff. The general use of tubular and open supply of working fluid, broken wire is particularly evident because of the working fluid can not reach the processing site and liquid leakage, the electrode wire is not uniform impact, coupled with the working fluid itself is a pulse oscillation source , So in its movement process, with the force changes will have a strong vibration (ie, shaking wire), in severe cases that cause broken wire. We DK7730B-type wire-cutting machine tools, the use of leak-jet method for the supply of working fluid, the successful improvement of the device. As shown, when the working fluid into the water
