Technical Field

[0001] This invention relates to the field of wire cutting machines, and in particular to a split-type high-precision wire cutting machine with adjustable cutting area length. Background Technology

[0002] A wire EDM machine is a machine tool that uses the principle of electrical discharge to process metal. It mainly uses a thin metal wire (usually copper or nickel alloy) as an electrode. Under the cooling and insulation of the working fluid (usually deionized water), it processes conductive materials into the required shape. Wire EDM machines are characterized by high precision, no cutting force, wide applicability, processing of complex shapes, and smooth cutting surfaces. They are widely used in mold manufacturing, aerospace, automotive industry, electronics industry, and medical device fields.

[0003] Traditional wire EDM machines have the metal wire fixedly mounted on the wire wheel, and the cutting area length is fixed. When cutting large objects, the cutting area length needs to be increased. When adjusting the length, the metal wire length needs to be changed and tensioned again, which is very troublesome.

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

[0019] according to Figure 1 and Figure 2 A split-type high-precision wire cutting machine with adjustable cutting area length includes a machine tool 1 and a worktable 2. The worktable 2 is located next to the machine tool 1. The machine tool 1 is equipped with a drive roller 6 and several wire wheels 9. Metal wire 10 is wound on the drive roller 6. The metal wire 10 is led out from the drive roller 6, passes through several wire wheels 9 in sequence, and is then guided back to the drive roller 6. The machine tool 1 is also equipped with an adjustment structure, which can directly adjust the length of the cutting area without changing the length of the metal wire 10, without having to re-tension the metal wire 10, thus greatly improving processing efficiency.

[0020] The adjustment structure includes a vertical moving structure for adjusting the length of the cutting area, a horizontal moving structure that cooperates with the vertical moving structure for not changing the length of the metal wire 10, and a base structure for mounting 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 mounted on the machine tool 1, the mounting plate 4 is mounted on the X-axis linear module 3, and the vertical bracket 5 is mounted 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 workpiece.

[0022] The drive roller 6 is mounted on the mounting plate 4 via a motor bracket 7. A drive motor 8 is mounted on the motor bracket 7 and is connected to the side of the drive roller 6. The drive motor 8 drives the drive roller 6 to rotate, causing the metal wire 10 to be pulled and cut through the workpiece. While passing through the workpiece, the metal wire 10 is excited by the current, forming an electric arc, which causes the metal wire 10 to melt and evaporate rapidly at the point of contact with the workpiece, thereby achieving cutting.

[0023] Two fixed wire frames 11 are horizontally installed at the bottom of the vertical support 5. The two fixed wire frames 11 are respectively installed on both sides of the vertical support 5. Each of the two fixed wire frames 11 is provided with a first sliding groove 12. A first slider 13 is simultaneously slidably connected to the two first sliding grooves 12. The first sliding edge cooperates with the first sliding track so that the first slider 13 will not detach from the two first sliding grooves 12.

[0024] The vertical moving structure includes a telescopic cylinder 15 and a second slider 16. The top of the vertical support 5 is provided with a second sliding groove 17, and the top of the second sliding groove 17 is provided with an opening. The telescopic cylinder 15 is installed at the opening. The telescopic rod inside the telescopic cylinder 15 extends and retracts downward. The second slider 16 is installed on the top of the telescopic rod. The second slider 16 is slidably connected to the second sliding groove 17. The second slider 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 movable wire frames 18, each with a third sliding groove 19. The two movable wire frames 18 are respectively installed on both sides of the vertical support 5. The two movable wire frames 18 are slidably connected to the slider through the third sliding groove 19. The second sliding edge cooperates with the second sliding track to prevent the second slider 16 from disengaging from the two third sliding grooves 19. When the tension remains unchanged, as the movable wire frame 18 rises, the movable wire frame 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 is perpendicular to the metal wire 10 between the wire wheel 9 on the right side of the movable wire frame 18.

[0026] Tension control springs 20 are 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 when adjusting the length of the cutting area. Both the first slider 13 and the second slider 16 are provided with locking nuts 21 that cooperate with the nut groove for locking structures.

[0027] The first slider 13 has a wheel hole 14 in the middle. A first set of wire wheels 9 are installed in the wheel hole 14 and on the left side of the fixed wire frame 11. The first set of wire wheels 9 are at the same height. A second set 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. The second set of wire wheels 9 are at the same height. 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. The size of its length determines the size of the workpiece that can be processed.

[0028] Compared with the prior art, the present invention provides a split-type high-precision wire EDM machine with adjustable cutting area length. The wire EDM machine has an adjustment structure that can directly adjust the length of the cutting area without changing the length of the metal wire, without having to re-tension the metal wire, thus greatly improving processing efficiency.
