Problems solved by technology

[0003] In the process of porous EDM drilling, while the workpiece material is removed by electric discharge, the electrodes are also constantly worn out. In order to realize batch hole group processing, the copper tube electrodes consume a lot, and often need to be manually replaced with new copper tubes, including Installing new copper pipes and dismantling waste copper pipes, too much manual participation leads to low drilling efficiency of EDM punching machine

[0004] In the prior art, for the feeding and replenishment of copper tubes, some enterprises have researched and used principle structures including electrode push strips and electrode turntables, so that copper tubes are discharged from the electrode turntable where the copper tubes are placed, but due to the placement of the electrode turntable Even if the electrode slots are pipes with different diameters and sizes, copper pipes of different specifications are placed, but it is difficult to clamp and position according to different diameters of copper pipes when cutting. The process is very disadvantageous

[0005] In addition, during the lowering process of the copper tube, because the electric spark rotary chuck drives the copper tube down and punches holes, the center positions of the upper end and the lower end of the copper tube are not on the same straight line, which not only easily leads to a large amount of scrapped copper tubes but also leads to perforated holes. The forming effect is poor, and the jump of the copper tube increases when rotating, especially for micro-holes with a hole diameter between 0.01mm-0.015mm. The coordinated setting and automatic clamping of the guide assembly and the positioning assembly are particularly important. Furthermore, after the drilling is completed, the slight vibration of the electrode may damage the newly punched hole on the surface of the workpiece, so the nozzle that automatically adjusts the position is also very important.
