Technical Field

[0001] This utility model belongs to the field of wire EDM machine technology, specifically a wire support structure for a wire EDM machine. Background Technology

[0002] A wire EDM machine is a device that cuts workpieces by using the electro-corrosion effect generated by pulse discharge between the electrode wire and the workpiece. It is mainly used to process metal molds and parts with various complex shapes. Its working principle is to use a high-frequency pulse power supply to generate spark discharge between the electrode wire and the workpiece, thereby eroding the metal. The cutting wire support structure can accurately guide the direction of the cutting wire, reduce the vibration of the cutting wire, and ensure cutting accuracy.

[0003] The existing wire EDM cutting wire support structure still has the following shortcomings: the fixed wheel of the existing wire EDM cutting wire support structure is not easy to replace. The fixed wheel will wear out due to long-term friction with the cutting wire, which will lead to a decrease in the cutting accuracy of the wire EDM machine, an increase in the roughness of the cut surface, and affect the quality of the processed workpiece. It will also make the tension of the cutting wire unstable and prone to wire breakage. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a wire cutting support structure for a wire EDM machine, which solves the problem that the fixed wheel of the existing wire cutting support structure is inconvenient to replace.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wire cutting support structure for a wire cutting machine, comprising a base, a connecting plate fixedly connected to the top of the base, a pair of connecting blocks fixedly connected to one side of the connecting plate, a pair of slide rails provided on the side of each connecting block away from the connecting plate, a slider slidably connected to each slide rail, an adjusting component provided on each slide rail, a clamping component provided on the side of the slider away from the slide rail, and a wire-fixing wheel provided on the side of the slider away from the slide rail.

[0006] As a further embodiment of this utility model: the adjustment component includes a nut, which is fixedly connected to one side of the slide rail. A threaded rod is threadedly connected to the nut, and a knob is coaxially fixedly connected to one end of the threaded rod. The other end of the threaded rod is rotatably connected to the slider.

[0007] As a further embodiment of this utility model: the clamping assembly includes a support frame one and a support frame two. Both the support frame one and the support frame two are fixedly connected to the side of the slider away from the slide rail.

A wedge-shaped clamping block is fixedly connected to the side of each nut two near the support frame two. A connecting block two is fixedly connected to the side of the wedge-shaped clamping block away from the nut two. A guide rod is fixedly connected to the support frame two. The outer periphery of the guide rod is slidably connected to the connecting block two.

[0008] As a further embodiment of this utility model: a rotating handle is coaxially fixedly connected to the top of the bidirectional threaded rod.

[0009] As a further embodiment of this utility model, a connecting groove is provided on one side of the slider.

[0010] As a further embodiment of this utility model: a connecting shaft is coaxially fixedly connected to one side of the guide wheel, and a fixing block is rotatably connected to one end of the connecting shaft, the fixing block being adapted to the connecting groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] like Figures 1-4 As shown, this utility model provides a technical solution:

[0021] A wire cutting machine cutting wire support structure includes a base 1, a connecting plate 2 fixedly connected to the top of the base 1, a pair of connecting blocks 3 fixedly connected to one side of the connecting plate 2, a pair of slide rails 4 provided on the side of each connecting block 3 away from the connecting plate 2, a slider 5 slidably connected on each slide rail 4, an adjustment component provided on each slide rail 4, a clamping component provided on the side of the slider 5 away from the slide rail 4, and a wire fixing wheel 6 provided on the side of the slider 5 away from the slide rail 4. The slider 5 can be fixed by the clamping component and the wire fixing wheel 6. The adjustment component can drive the slider 5 to slide on the slide rail 4, thereby adjusting the position of the wire fixing wheel 6. The cutting wire passes through each pair of wire fixing wheels 6 and is positioned between the pair of wire fixing wheels 6.

[0022] The adjustment assembly includes a nut 7, which is fixedly connected to one side of the slide rail 4. A threaded rod 8 is threadedly connected to the nut 7. A knob 9 is coaxially fixedly connected to one end of the threaded rod 8, and the other end of the threaded rod 8 is rotatably connected to the slider 5. The knob 9 drives the threaded rod 8 to screw into the nut 7, and the threaded rod 8 drives the slider 5 to move.

[0023] The clamping assembly includes a support frame 10 and a support frame 21. Both support frames 10 and 21 are fixedly connected to the side of the slider 5 away from the slide rail 4. A bidirectional threaded rod 12 is rotatably connected to the support frame 10. A pair of nuts 23 are threadedly connected to the bidirectional threaded rod 12. A wedge-shaped clamping block 14 is fixedly connected to the side of each nut 211 near the support frame 21. A connecting block 25 is fixedly connected to the side of the wedge-shaped clamping block 14 away from the nut 23. A guide rod 16 is fixedly connected to the support frame 21. The outer periphery of the guide rod 16 is slidably connected to the connecting block 215. A rotating handle 17 is coaxially fixedly connected to the top of the bidirectional threaded rod 12. By rotating the handle 17, the bidirectional threaded rod 12 can be rotated. The bidirectional threaded rod 12 drives the pair of nuts 213 to move towards each other. The nuts 213 drive the wedge-shaped clamping block 14 to move. The wedge-shaped clamping block 14 slides on the guide rod 16 through the connecting block 215.

[0024] A connecting groove 18 is provided on one side of the slider 5, and a connecting shaft 19 is coaxially fixedly connected to one side of the fixed wheel 6. A fixing block 20 is rotatably connected to one end of the connecting shaft 19. The fixing block 20 is adapted to the connecting groove 18 and can be inserted into the connecting groove 18. A pair of inclined surfaces adapted to the wedge-shaped clamping blocks 14 are provided on the fixing block 20. The pair of wedge-shaped clamping blocks 14 can fix the fixing block 20 in the connecting groove 18 by clamping the inclined surfaces on the fixing block 20. The fixed wheel 6 can drive the connecting shaft 19 to rotate on one side of the fixing block 20.

[0025] The working principle of this utility model is as follows:

[0026] Rotating the handle 17 can drive the bidirectional threaded rod 12 to rotate, which in turn drives a pair of nuts 13 to move towards each other. The nuts 13 drive the wedge-shaped clamping block 14 to move. The wedge-shaped clamping block 14 slides on the guide rod 16 through the connecting block 15. The fixing block 20 can be inserted into the connecting groove 18. The fixing block 20 has a pair of inclined surfaces that are adapted to the wedge-shaped clamping block 14. When the pair of wedge-shaped clamping blocks 14 are close to each other, the fixing block 20 can be fixed in the connecting groove 18 by clamping the inclined surfaces on the fixing block 20, so that the fixed wheel 6 and the slider 5 are fixed together. When the pair of wedge-shaped clamping blocks 14 are far apart, the fixing block 20 can be released, which facilitates the timely replacement of the worn fixed wheel 6, effectively maintains the stable operation of the cutting line, ensures cutting accuracy and processing quality, and significantly shortens the replacement time of the fixed wheel 6, reduces equipment downtime, and improves production efficiency.

[0027] The screw rod 8 is screwed into the nut 7 by the knob 9, and the screw rod 8 drives the slider 5 to slide on the slide rail 4, thereby adjusting the position of the fixed line wheel 6. When the fixed line wheel 6 is worn to a certain extent, it can be compensated by fine adjustment of position, which can extend the service life of the fixed line wheel 6, reduce equipment maintenance costs and replacement frequency, and at the same time, it can also accurately control the tension of the cutting line, which greatly improves the cutting accuracy.

[0028] The cutting wire passes through each pair of fixed-line wheels 6. The cutting wire is set between a pair of fixed-line wheels 6. The fixed-line wheels 6 rotate with the cutting wire. The fixed-line wheels 6 can drive the connecting shaft 19 to rotate on one side of the fixed block 20.

[0029] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
