[0002] In modern industrial production, multi-wire cutting technology is playing an increasingly important role as an advanced material processing method. Through the high-speed reciprocating motion of metal wires, multi-wire cutting can simultaneously cut hard and brittle materials, such as semiconductor materials and silicon wafers, into multiple thin slices in one operation. It boasts significant advantages such as high efficiency, high precision, and low loss, and has gradually become the mainstream method in fields such as silicon wafer cutting, gradually replacing traditional methods such as internal circle cutting.

[0003] In existing technology, multiple cutting lines are wound parallel and evenly around a guide wheel, forming a ring-shaped cutting wire mesh. The drive system drives the guide wheel to rotate, causing the cutting lines to circulate back and forth at a high speed, providing power for the cutting process.

[0004] However, existing technologies require disassembling the cutting line for adjustment when adjusting the number of cutting blades and the cutting spacing, which is time-consuming and labor-intensive. Utility Model Content

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-3 This embodiment describes a multi-wire cutting device for a multi-wire cutting machine tool, comprising: a cutting chamber 1, a fixed end of a hydraulic cylinder 2 connected to the top wall of the cutting chamber 1, and a telescopic end of the hydraulic cylinder 2 connected to a cutting machine frame 3. Three rotating shafts 4 are rotatably connected inside the cutting machine frame 3, with the axes of the two lower rotating shafts 4 located on the same horizontal plane. Each rotating shaft 4 is provided with a sliding groove 5, and a grooved wheel 6 is slidably connected in the sliding groove 5. The grooved wheel 6 is connected to a sleeve 7. A cutting wire 8 is provided in the groove of the three grooved wheels 6 on the three rotating shafts 4. The sleeve 7 of the three grooved wheels 6 is rotatably connected to a slide 9. The positions of the multiple slides 9 are adjusted by a drive mechanism 10, which is connected to the cutting machine frame 3. Each rotating shaft 4 is connected to the output shaft of a corresponding motor 11, and the motor 11 is connected to the cutting machine frame 3.

[0021] During cutting, the material to be cut is fixed to the bottom wall of the cutting chamber 1 by a clamp. The motor 11 is turned on, and the motor 11 rotates through the rotating shaft 4, the slide groove 5, and the grooved wheel 6. The three grooved wheels 6 in the same group drive the cutting line 8 to rotate. The hydraulic cylinder 2 controls the cutting frame 3 to descend, which drives the cutting line 8 to descend and cut the material clamped at the bottom. When it is necessary to adjust the cutting spacing, the position of the slide 9 is adjusted by the drive mechanism 10. The slide 9 drives the three grooved wheels 6 in the same group to slide along the slide groove 5 through the sleeve 7 which is axially limited, so as to complete the adjustment of the spacing between the cutting lines 8. The adjustment will not affect the power transmission. In this way, the spacing between different cutting lines 8 can be adjusted to meet different cutting needs.

[0024] The lower part of the cutting frame 3 is slidably connected to the slide rod 12, and the slide rod 12 is connected to the bottom wall of the cutting chamber 1.

[0025] The cutting frame 3 slides along the slide bar 12 to make the cutting more stable.

[0026] The cutting line 8 is equipped with a horizontal liquid pipe 13. One end of the horizontal liquid pipe 13 is connected to the coolant pump, and the other end of the horizontal liquid pipe 13 is closed. Multiple nozzles 14 are connected to the lower part of the horizontal liquid pipe 13.

[0027] The liquid pump draws coolant and injects it into the horizontal liquid pipe 13, which is then discharged through the nozzle 14. The nozzle 14 sprays liquid in an umbrella shape to cover the lower area, so that the cutting line 8 can be cooled even if the cutting spacing is adjusted.
