Description

The invention relates to the field of electrochemical processing methods and can be used in mechanical engineering for the perforation of thin-walled parts from high-strength and solid conductive materials (for example, drums of juice extractors, deflectors, anti-vibration screens)

The purpose of the invention is to increase the productivity of processing,

Figure 1 shows the device, a general view; on Fig - the same section in the center; FIG. 03 is the same section along the gas removal channels; FIG. on Fig - the same, a section on channels of supply of electrolyte in chambers; Fig. 5 is a block diagram of the system ensuring the operation of the head.

The device 1 comprises a rotor 2 with high pressure chambers 3 installed in it, with metal nozzles 4 covered with a dielectric layer 5, discharge electrodes 6 inserted into the high pressure chambers and drive gear 7, a stator 8 having a tire 9 for supplying a positive pole a high voltage source, insulated by dielectric insert 10, rotor position clamps 11, channels 12 for venting gas from high pressure chambers, channels 13 for supplying electric

high pressure chambers, pipeline 14 for removal of gas from the head, pipeline 15 for supplying electrolyte to the head and mounting flange 16c

The device works as follows

The hole is pierced by the impact of the jet on the part and the local electrochemical anodic dissolution of the metal, while creating pressure in the electrolyte jet uses electrical discharge in the liquid when the electrical discharge energy is converted into kinetic energy of jet motion.

The device has one working position at which the opening is processed, and auxiliary positions for filling the chambers with electrolyte and removing the gases formed. The device is mounted on the spindle of a specialized electrochemical machine using a mounting flange 16 mounted on the stator 8, connecting

The pipes 15 and 14, respectively, are connected to the pumping electrolyte unit and the drain tank, and the bus 9 to the high-voltage pulsed voltage source 17, the head body (the negative pole of the high-voltage IP) is also connected to the negative pole of the process source 18

10 current (the positive is connected to the part), and one discharge electrode is electrically connected to the camera body 30. Through conduit 15, the electrolyte enters the channels 13 located in the stator and is supplied through them to the high pressure chambers in each auxiliary position.

With the help of pump 19 pumped ra-1 barrel element into device 1 through

20 filter 20 from the drain tank 21 and is cleaned of solid micro-inclusions With the help of a high-voltage source 17, which creates an electrical discharge in a liquid, forms a jet

25 electrolyte directed to the part synchronously with switching on the voltage source 17, a technological current source is connected to the interelectrode gap between the head and the workpiece 22, allowing to organize local anodic removal of the metal from the part in contact with the electrolyte stream0 After the hole formation process in the part, the processing head is turned by means of the actuator 23 to the next position The residual electrolyte and the gases generated as a result of the electric discharge are continuously removed Are in the drain tank 21 and pumped into the head new portions of the electrolyte
