Description

Technical Field

[0002] Wire cutting machine tools use electrode wire (molybdenum wire, tungsten-molybdenum wire, etc.) as tool electrode. Under the action of pulse power supply, spark discharge is formed between the tool electrode and the workpiece. The spark channel instantly generates a large amount of heat, causing the workpiece surface to melt or even vaporize, thereby achieving the purpose of processing the workpiece.

[0003] The existing publication number CN113070538A discloses a medium-speed wire cutting machine with fast threading, which relates to the field of wire cutting machines.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The penetration component includes a mounting block, and a second V-shaped groove is provided on one side of the mounting block. The second V-shaped groove facilitates the penetration of the cutting line, and the installation of the cutting line is more convenient and quick. The mounting block is provided with a second wire-passing gap at the bending part of the second V-shaped groove.

[0027] 3. A counterweight is slidably installed on the guide rod. The guide rod is located above the counterweight and is covered with a spring that acts on the counterweight.

The first motor can drive the drum to rotate, thereby realizing the operation of retracting and releasing the wire. Due to the setting of the driven synchronous pulley, the driving synchronous pulley and the synchronous belt, the rotation of the lead screw can be realized, and then the movement of the moving plate can be realized, which offsets the position change caused by the retraction and release of the cutting wire, thereby ensuring the accuracy of the cutting wire position.

[0029] 5. A first guide groove is installed on the top of the Y-axis sliding seat, a second guide groove is arranged at one end of the first guide groove, and a liquid outlet pipe is installed at one end of the second guide groove.
