[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A three-axis electrical discharge machining (EDM) device, such as Figures 1-4 As shown, the machine includes a base 1, a shaft support bracket 4 connected to one side of the top of the base 1, wire take-up and unwinding shafts 20 connected to both sides of the shaft support bracket 4, and I-beam wheels 21 movably connected to the center of one side of each of the two wire take-up and unwinding shafts 20. A wire guide wheel 22 is connected to one side of the top of the shaft support bracket 4, and two transition guide wheels 23 are also connected to one side of the top of the shaft support bracket 4. A cutting roller fixing seat 14 is provided on one side of the shaft support bracket 4. Wire cutting rollers 11 are movably connected to one side of the cutting roller fixing seat 14 near the upper and lower sides, and an upper conductive rod 10 and a lower conductive rod 13 are respectively connected to one side of the cutting roller fixing seat 14 near the upper and lower sides. A wire guide roller 12 is provided on one side of the cutting roller fixing seat 14, and the right side of the wire guide roller 12 is movably connected to one side of the cutting roller fixing seat 14 near the center. A lifting arm 8 is connected to the top of one side of the cutting roller fixing seat 14, and a meter counting guide wheel 9 is movably connected to the top of one side of the lifting arm 8.

[0031] When the operator wants to use the EDM triaxial cutting device to cut a workpiece, the operator starts the wire guide slide 19 through an external power supply. This allows adjustment of the working distance between the two wire guide rollers 22 connected to the wire guide slide base 18, facilitating better guidance of the two wire guide rollers 22. After the working distance between the two wire guide rollers 22 connected to the two wire guide slide bases 18 is adjusted, the operator winds one end of the wire wound on the I-beam spool 21 around the adjacent wire guide rollers 22, the transition guide roller 23, and the meter guide roller 9 from both sides. At the same time, the wire on the rear side is wound around the bottom of the tension guide roller 5. When the two wire guide rollers 22 are in place, the operator starts the wire guide slide 19 through an external power supply. This allows the operator to adjust the working distance between the two wire guide rollers 22 and the wire guide roller 2 ... After one end of the wire on the I-beam 21 is passed around the two metering guide rollers 9, the worker then passes one end of the wire on the two I-beam 21 around the wire guide roller 12. Simultaneously, one end of the wire on the two I-beam 21 passes around the bottom of the wire cutting roller 11 and partially winds it onto the top wire cutting roller 11. Once the wire on the two I-beam 21 is partially wound onto the top wire cutting roller 11, the worker uses a drive device to rotate the upper and lower traction timing pulleys 24, thereby rotating the two wire cutting rollers 11. This process winds the wire on the two I-beam 21 onto the wire. A triangular wire harness structure is formed on the wire guide roller 12 and the two wire cutting rollers 11. When the wires on the two I-beam rollers 21 are wound around the wire guide roller 12 and the two wire cutting rollers 11, the operator places the workpiece on the fixture table 15. Then, the operator activates the upper conductive rod 10 and the lower conductive rod 13 through an external power supply. This causes the upper conductive rod 10 and the lower conductive rod 13 to discharge onto the triangular wire harness structure wound on the wire guide roller 12 and the two wire cutting rollers 11. The high temperature generated by the discharge melts or oxidizes the workpiece placed on the fixture table 15, thereby achieving precise cutting. At the same time, the workpiece placed on the fixture table 15 must be... When cutting different parts of the workpiece on the fixture table 15, the operator starts the X-axis guide rail motor 17 and the Y-axis guide rail motor 3 through an external power supply. This allows the workpiece placed on the fixture table 15 to move in a horizontal or vertical plane, thus enabling the cutting of different parts of the workpiece. At the same time, when the operator needs to adjust the height of the wire cutting rollers 11, the operator starts the lifting control motor 6 through an external power supply. This quickly moves the two wire cutting rollers 11 up or down, thus quickly adjusting the wire tension on the two wire cutting rollers 11 to cut the workpiece.

[0032] like Figure 1 and Figure 3As shown, the center of the rear end of the meter guide wheel 9 and the center of the rear side of the two wire cutting rollers 11 are connected to a shaft. The center of one side of the inner cavity of the lifting arm 8 and the center of one side of the inner cavity of the cutting roller fixing seat 14 near the upper and lower sides are provided with rotating holes. Several shafts pass through the inner cavities of adjacent rotating holes and are connected to traction synchronous pulleys 24. A traction synchronous pulley 24 is also provided at the bottom of one side of the cutting roller fixing seat 14. A traction synchronous belt 25 is fitted on each of the two adjacent traction synchronous pulleys 24, and the two adjacent traction synchronous pulleys 24 are connected by the transmission of the adjacent traction synchronous belt 25.

[0033] When the worker winds a portion of the wires on the two I-beams 21 onto the top wire cutting roller 11, the worker then drives the upper and lower traction timing pulleys 24 to rotate via a drive device. This causes the two upper and lower traction timing pulleys 24 to rotate synchronously via two adjacent traction timing belts 25, which in turn causes the two central traction timing pulleys 24 to rotate. Consequently, the two central traction timing pulleys 24 drive the two wire cutting rollers 11 to rotate, thus winding the wires on the two I-beams 21 onto the wire guide roller 12 and the two wire cutting rollers 11 to form a triangular wire harness structure.

[0034] like Figure 1 and Figure 2 As shown, a cable tray seat 18 is connected to one side of the top of the bearing bracket 4, and two cable guide wheels 22 are connected to one side of the cable tray seat 18. A cable tray 19 is provided on one side of the cable tray seat 18, and one side of the cable tray 19 is connected to the center of one side of the cable tray seat 18.

[0035] When the operator needs to adjust the working distance between the two cable guide wheels 22 connected to the two cable slide bases 18, the operator starts the cable slide 19 through an external power supply. This allows the two cable guide wheels 22 connected to the cable slide base 18 to move to the sides or close inwards, thereby adjusting the working distance between the two cable guide wheels 22 connected to the cable slide base 18 and facilitating better guidance of the two cable guide wheels 22.

[0036] like Figure 1 As shown, a lifting column 7 is connected to one side of the lifting arm 8, and the bottom of the lifting column 7 is connected to one side of the top of the base 1. A tension guide wheel 5 is provided on one side of the lifting column 7, and the rear end of the tension guide wheel 5 is connected to one side of the center of the lifting column 7.

[0037] When the operator needs to adjust the height of the wire cutting rollers 11, the operator starts the lifting control motor 6 via an external power source. When powered on, the lifting control motor 6 drives the lifting arm 8 to move up or down. As the lifting arm 8 moves up or down, it drives the two wire cutting rollers 11 to move up or down via the cutting roller fixing seat 14. This achieves a quick adjustment of the height of the two wire cutting rollers 11, allowing the operator to easily adjust the wire tension on the two wire cutting rollers 11 for cutting the workpiece, thus facilitating practical use.

[0038] like Figure 1 As shown, a lifting control motor 6 is installed at the top of the lifting column 7, and the bottom of the lifting control motor 6 is connected to the center of the top of the lifting column 7.

[0039] The staff can start the lifting control motor 6 by connecting an external power source, so that the lifting control motor 6 can quickly drive the lifting arm 8 to move up or down when it is powered on.

[0040] like Figure 1 As shown, an X-axis guide rail slide 16 is movably connected to one side of the top of the machine base 1, and a Y-axis guide rail slide 2 is movably connected to the top of the X-axis guide rail slide 16. A connecting groove is provided near the center of the top of the inner cavity of the Y-axis guide rail slide 2, and a tooling table 15 is connected to the inner cavity of the connecting groove.

[0041] When the operator needs to adjust the position of the fixture table 15 to cut different parts of the workpiece, the operator starts the X-axis guide rail motor 17 and the Y-axis guide rail motor 3 through an external power supply. This allows the fixture table 15 to move in a horizontal or vertical plane, thus facilitating the adjustment of its position. This makes it easier for the operator to cut different parts of the workpiece placed on the fixture table 15, thereby improving the processing efficiency of the workpiece to a certain extent.

[0042] like Figure 1 As shown, an X-axis guide rail motor 17 is provided on one side of the X-axis guide rail slide 16, and one side of the X-axis guide rail motor 17 is connected to the center of one side of the X-axis guide rail slide 16. A Y-axis guide rail motor 3 is provided on one side of the Y-axis guide rail slide 2, and one side is connected to the center of one side of the Y-axis guide rail slide 2.

[0043] The operator can start the X-axis guide rail motor 17 or the Y-axis guide rail motor 3 by connecting an external power source, so that the X-axis guide rail motor 17 or the Y-axis guide rail motor 3 can quickly move the tooling table 15 in the horizontal or vertical plane when powered on.

[0044] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
