[0018] The preferred embodiments of the present invention are described in detail below so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] according to Figure 1 and Figure 2 A split high-precision wire cutting machine capable of adjusting the length of a cutting area comprises a machine tool 1 and a workbench 2, wherein the workbench 2 is arranged beside the machine tool 1, and a driving roller 6 and a plurality of wire wheels 9 are installed on the machine tool 1, a metal wire 10 is wound around the driving roller 6, and the metal wire 10 is led out from the driving roller 6, passes through a plurality of wire wheels 9 in sequence, and then is led back to the driving roller 6, and an adjustment structure is also installed on the machine tool 1, which can directly adjust the length of the cutting area when the length of the metal wire 10 remains unchanged, without the need to re-tighten the metal wire 10, thereby greatly improving the processing efficiency.

[0020] The adjustment structure includes a vertical moving structure for adjusting the length of the cutting area, a horizontal moving structure cooperating with the vertical moving structure for not changing the length of the metal wire 10, and a base structure for installing the vertical moving structure and the horizontal moving structure.

[0021] The base structure includes an X-axis linear module 3, a mounting plate 4 and a vertical bracket 5. The X-axis linear module 3 is installed on the machine tool 1, the mounting plate 4 is installed on the X-axis linear module 3, and the vertical bracket 5 is installed on the mounting plate 4. The X-axis linear module 3 is used to adjust the position of the metal wire 10 during cutting so that it is close to the processed part.

[0022] The driving roller 6 is mounted on the mounting plate 4 via a motor bracket 7, and a driving motor 8 is mounted on the motor bracket 7. The driving motor 8 is connected to the side of the driving roller 6. The driving motor 8 drives the driving roller 6 to rotate, so that the metal wire 10 is pulled and cut through the workpiece. While passing through the workpiece, the metal wire 10 is excited by the current to form an arc, so that the metal wire 10 quickly melts and evaporates at the place where it contacts the workpiece, thereby achieving cutting.

[0023] Two fixed wire racks 11 are horizontally installed at the bottom of the vertical bracket 5, and the two fixed wire racks 11 are respectively installed on both sides of the vertical bracket 5. A first slide groove 12 is opened on the two fixed wire racks 11, and a first slider 13 is slidably connected to the two first slide grooves 12 at the same time. The first sliding edge cooperates with the first slideway so that the first slider 13 will not fall out of the two first slide grooves 12.

[0024] The vertical moving structure includes a telescopic cylinder 15 and a second slide block 16. A second slide groove 17 is provided on the top of the vertical bracket 5. An opening is provided on the top of the second slide groove 17. The telescopic cylinder 15 is installed at the opening. The telescopic rod in the telescopic cylinder 15 is telescoped downward. The second slide block 16 is installed on the top of the telescopic rod. The second slide block 16 is slidably connected to the second slide groove 17. The second slide block 16 moves up and down through the telescopic cylinder 15, thereby adjusting the length of the cutting area.

[0025] The horizontal moving structure includes two moving wire racks 18, and the two moving wire racks 18 are each provided with a third slide groove 19. The two moving wire racks 18 are respectively installed on both sides of the vertical bracket 5. The two moving wire racks 18 are slidably connected with the slider through the third slide groove 19, and cooperate with the second slide rail through the second sliding edge, so that the second slider 16 will not separate from the two third slide grooves 19. Under the condition that the tension force remains unchanged, when the moving wire rack 18 rises, the moving wire rack 18 moves to the left, and at the same time, the first slider 13 also moves to the left, ensuring that the wire wheel 9 in the wheel hole 14 and the metal wire 10 between the wire wheel 9 on the right side of the moving wire rack 18 are vertical.

[0026] A tension control spring 20 is provided between the first slider 13 and the left side of the first slide groove 12, and between the second slider 16 and the right side of the third slide groove 19, for controlling the tension force when adjusting the length of the cutting area. The first slider 13 and the second slider 16 are both provided with a locking structure in which a locking nut 21 cooperates with a nut groove.

[0027] A wheel hole 14 is provided in the middle of the first slider 13, and a first group of wire wheels 9 are installed in the wheel hole 14 and on the left side of the fixed wire frame 11, and the heights of the first group of wire wheels 9 are the same. A second group of wire wheels 9 are installed at the bottom of the second slider 16 and on the right side of the movable wire frame 18, and the heights of the second group of wire wheels 9 are the same. The length of the metal wire 10 between the wire wheel 9 in the wheel hole 14 and the wire wheel 9 on the right side of the movable wire frame 18 is the length of the cutting area, and the size of the length determines the size of the workpiece that can be processed.

[0028] Compared with the prior art, the present invention provides a split high-precision wire cutting machine capable of adjusting the length of the cutting area. The wire cutting machine has an adjustment structure, which can directly adjust the length of the cutting area without re-tensioning the wire, thereby greatly improving the processing efficiency.
