Principle of operation

The spark erosion perforating machine perforates an object to be perforated placed above the mounting base 10 by inserting one end of an electrode into the rotating shaft 23 and passing through the driving block 14, adjusting the height of the driving block 14 and passing the other end of the electrode through the electrode hole 20 inside the fixed head 18, and rotating and energizing the electrode by means inside the driving block 14.

The protective shell 29 is a protective system surrounding one end of the electrode between the rotating shaft 23 and the fixed head 18, when the electrode is installed, the handles 41 on the two sides are pulled to enable the sliding block 31 to slide in the second sliding groove 30 and slide out the installation supporting plate 33, the connecting block 42 at the port of the insulating layer 34 is embedded into the connecting groove 43 at the port of the other half of the insulating layer 34 and tightly connected through the

When the mounting support plate 33 is pulled out, the toggle groove 35 outside the insulating layer 34 toggles the rotating rod 56 to enable the other end of the rotating rod to rotate to prop the second slide block 59 open, the second slide block 59 slides out of the second roller 62 to abut against the electrode, the electrode is annularly surrounded and propped by the plurality of second slide blocks 59, the electrode is prevented from bending and deforming during perforation, the second roller 62 can rotate along with the rotation of the electrode when the electrode rotates, and an upward sliding force can be generated to straighten the surface of the electrode when the second roller 62 rotates through the thread rail 63.

The connecting rod 39 is ejected by the spring 40 due to the constraint of being separated from the protective housing 29 when the mounting support plate 33 is pulled out, while the mounting plate 48 is in contact with the electrode and is rotated by the second rotating shaft 47 to engage the electrode surface, the roller 51 can rotate while transferring heat of the electrode surface to the heat sensing piece 49 by the roller 51 contacting the electrode surface, detect whether the electrode surface is overheated by the heat sensing piece 49, when the heat sensing piece 49 detects the electrode overheating, it transmits a signal to the connection pipe 27, so that the connection pipe 27 transmits the cooling liquid in the cooling liquid pipe 28 to the liquid passing pipe 26 and flows out to the outer surface of the second roller 62 through the liquid passing groove 64, the second roller 62 rotates because the inner space of the second mounting groove 61 is small, therefore, the liquid in the liquid passing tank 64 can be pressed out by reducing the air pressure in the second mounting groove 61, and the outer surface of the electrode can be cooled by the second roller 62.
