Description

Technical Field

[0001] This utility model belongs to the field of wire EDM processing technology, specifically a wire EDM machine tool that facilitates the replacement of cutting wires. Background Technology

[0002] Wire EDM machines are machine tools that use the principle of electric spark discharge to cut metal. Their basic working principle is to use a continuously moving thin metal wire as an electrode to remove metal through pulsed spark discharge, thereby achieving the cutting and shaping of the workpiece. Currently, when the cutting wire of a wire EDM machine is damaged or broken, the operator needs to disassemble the cutting wire, unload it, and replace it. Due to the complex structure, it is difficult to disassemble the cutting wire, which increases the disassembly process and makes it inconvenient for the operator to replace the cutting wire at any time. Therefore, there is a need for a wire EDM machine that allows for easy replacement of the cutting wire. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a wire EDM machine tool that facilitates the replacement of cutting wires. It solves the problem that after the cutting wire is damaged or broken, the operator needs to disassemble and replace the cutting wire. Due to the complex structure, it is difficult to disassemble the cutting wire, which increases the disassembly process and makes it inconvenient for the operator to replace the cutting wire at any time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting machine tool for easy replacement of cutting wires, comprising a machine tool body, a bracket fixedly connected to the machine tool body, a support plate mounted on the bracket, a threaded rod threadedly engaged on the support plate, a rotating handle fixedly connected to the top end of the threaded rod, a bearing mounted at the bottom end of the threaded rod, a pressure block fixedly connected to the bottom side of the bearing, a cutting wire engaged at the bottom side of the pressure block, a first pulley engaged on the cutting wire, the first pulley being fixedly connected to the bracket, and a second pulley engaged on the cutting wire... The wheel is fixedly connected to the bracket. A third pulley is snapped onto the cutting line. The third pulley is fixedly connected to the machine tool body. A first connecting block is snapped onto the cutting line. The first connecting block is fixedly connected to the machine tool body. A positive electrode is installed on the first connecting block. The positive electrode is snapped onto the cutting line. A negative electrode is snapped onto the cutting line. A second connecting block is fixedly connected to the negative electrode. The second connecting block is snapped onto the cutting line. The second connecting block is fixedly connected to the support plate. A fourth pulley is snapped onto the cutting line. The fourth pulley is fixedly connected to the bracket.

[0005] As a further embodiment of this utility model: a baffle is installed on the machine tool body, and the baffle is fixedly connected to the bracket.

[0006] As a further embodiment of this utility model: the machine tool body is provided with a plurality of drainage holes, and a water storage tank is provided below the drainage holes, and the water storage tank is fixedly connected to the machine tool body.

[0007] As a further embodiment of this utility model: two guide plates are fixedly connected to the inner wall of the water storage tank, and a groove is provided on one side of the guide plate corresponding to the water storage tank.

[0009] As a further embodiment of this utility model: four anti-slip pads are installed on the bottom side of the water storage tank, and the anti-slip pads are respectively arranged at the four corners of the bottom side of the water storage tank.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This wire EDM machine, which facilitates wire replacement, is equipped with a machine body, bracket, support plate, threaded rod, rotating handle, pressure block, cutting wire, first pulley, second pulley, third pulley, and fourth pulley. When replacing the cutting wire, the operator rotates the rotating handle, causing the threaded rod on the support plate to rotate. The threaded rod pulls the pressure block upwards, loosening the cutting wire on the pressure block. The operator then pulls the cutting wire out, causing the first, second, third, and fourth pulleys to rotate until the cutting wire is completely withdrawn from the wire EDM machine. This simplifies the wire replacement process, allowing operators to easily change the cutting wire at any time, improving efficiency, and saving manpower and resources.

[0012] 2. This wire EDM machine, which facilitates the replacement of cutting lines, is equipped with a machine body, drainage holes, a water tank, a guide plate, and a groove. When water is generated during the operation of the wire EDM machine, it flows down from the drainage holes, onto the guide plate on the water tank, and then flows along the inclined surface of the guide plate into the groove to accumulate. This facilitates the centralized treatment of water generated during the operation of the wire EDM machine, preventing water from accumulating on the machine surface and causing corrosion, thus improving the functionality of the wire EDM machine.

[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: a wire cutting machine tool that facilitates the replacement of cutting wires, including a machine tool body 1, a baffle 17 installed on the machine tool body 1, and a fixed connection between the baffle 17 and the bracket 2. Because of the baffle 17, when the wire cutting machine tool generates excessive water during operation, the baffle 17 prevents the water from flowing out in all directions, which facilitates the centralized treatment of water and improves the functionality of the machine tool.

[0019] The machine tool body 1 has several drainage holes 18. A water storage tank 19 is located below the drainage holes 18 and is fixedly connected to the machine tool body 1. A bracket 2 is fixedly connected to the machine tool body 1. A support plate 3 is installed on the bracket 2. A threaded rod 4 is threadedly connected to the support plate 3. A handle 5 is fixedly connected to the top of the threaded rod 4. A bearing 6 is installed at the bottom of the threaded rod 4. A pressure block 7 is fixedly connected to the bottom side of the bearing 6. Because of the bearing 6, the threaded rod 4 is limited while ensuring that the threaded rod 4 can rotate normally, which improves the stability of the rotation of the threaded rod 4. Two guide plates 20 are fixedly connected to the inner wall of the water storage tank 19. A groove 21 is opened on one side of the guide plate 20 corresponding to the water storage tank 19. Because of the guide plate 20, water flows into the water storage tank 19 and converges on the guide plate 20, and finally accumulates in the groove 21, preventing water from accumulating at the four corners of the water storage tank 19 and thus preventing all the water from being discharged, which improves the functionality of the machine tool.

[0020] A water pipe 22 is provided on one side of the groove 21. The water pipe 22 is fixedly connected to the water storage tank 19. A water valve 23 is installed on the water pipe 22. Because of the water valve 23, when water is discharged, the operator turns the water valve 23, and the water flows out from the groove 21 in the water storage tank 19 and then is discharged from the water pipe 22. This makes it easy for the operator to control the amount of water discharged and prevent the water from being discharged too quickly and causing water to spill. A cutting line 8 is clamped on the bottom side of the pressure block 7. A first pulley 9 is clamped on the cutting line 8. The first pulley 9 is fixedly connected to the bracket 2. A second pulley 10 is clamped on the cutting line 8. The second pulley 10 is fixedly connected to the bracket 2. A third pulley 11 is clamped on the cutting line 8. The third pulley 11 is fixedly connected to the machine tool body 1. A first connecting block 12 is clamped on the cutting line 8. 2 is fixedly connected to the machine tool body 1. A positive electrode 13 is installed on the first connecting block 12. The positive electrode 13 is interlocked with the cutting line 8. A negative electrode 14 is interlocked on the cutting line 8. A second connecting block 15 is fixedly connected to the negative electrode 14. The second connecting block 15 is interlocked with the cutting line 8. The second connecting block 15 is fixedly connected to the support plate 3. A fourth pulley 16 is interlocked on the cutting line 8. The fourth pulley 16 is fixedly connected to the bracket 2. Four anti-slip pads 24 are installed on the bottom side of the water tank 19. The anti-slip pads 24 are respectively arranged at the four corners of the bottom side of the water tank 19. Because of the anti-slip pads 24, the water tank 19 is prevented from directly contacting the ground, which increases the friction of the bottom side of the water tank 19, prevents the machine tool from accidentally sliding sideways and causing cutting failure, and improves the overall stability of the machine tool.

[0021] The working principle of this utility model is as follows: When the wire EDM machine is working, the operator places the object on the machine and starts the positive electrode 13 and the negative electrode 14. After the cutting wire 8 generates an electric spark, the object is cut. When the wire EDM machine generates water, the water flows down from the drainage hole 18 and flows to the guide plate 20 on the water tank 19. The water flows along the inclined surface of the guide plate 20 and accumulates in the groove 21. When the water is discharged, the operator turns the water valve 23, and the water flows out from the groove 21 in the water tank 19 and then is discharged from the water pipe 22. When the cutting wire 8 is replaced, the operator turns the handle 5 to drive the threaded rod 4 on the support plate 3 to rotate. The threaded rod 4 pulls the pressure block 7 to move upward. After the cutting wire 8 on the pressure block 7 is loosened, the operator pulls the cutting wire 8. The cutting wire 8 drives the first pulley 9, the second pulley 10, the third pulley 11 and the fourth pulley 16 to rotate until the cutting wire 8 is completely pulled out of the wire EDM machine.
