Description

Technical Field

[0001] The utility model relates to the technical field of cutting devices, in particular to a cutting device for a wire cutting machine tool. Background Technique

[0002] Wire cutting (also known as electric discharge cutting or electric discharge machining) is a precision machining technology, usually used for cutting conductive materials. Its basic principle is to use electric discharge to remove materials from the surface of the workpiece, and the machining is carried out through the discharge channels formed in the working fluid (usually deionized water or dielectric liquid). The publication number CN206824782U discloses a cutting device for a wire cutting machine tool, including a workbench. One end of the upper surface of the workbench is processed with a group of strip-shaped grooves. Each strip-shaped groove is provided with a slide rail, and each slide rail is provided with an electrically controlled moving body. The upper surface of each electrically controlled moving body is provided with an electrically controlled telescopic rod with an upward telescopic end. The opposite inner surfaces of the electrically controlled telescopic rods are processed with first circular grooves. A first rotating rod is arranged in the group of first circular grooves, and a wire reel A is sleeved on the first rotating rod. The beneficial effect of this utility model is that this device can give the operation track of the cutting wire more precisely and stably, thereby improving the efficiency, and it has good flexibility, high precision, and fast cutting. However, during the actual operation of this cutting device, there is no guiding structure for the cutting wire. During the process of the cutting wire moving from the wire reel A to the guide wheel A, there is no guiding mechanism to guide and protect the cutting wire, which causes the cutting wire to be worn during this process, affecting the cutting effect and precision. Moreover, during the process of the cutting wire being wound from the guide wheel B to the wire reel B, it is impossible to ensure that the cutting wire is evenly wound on the surface of the wire reel B, which will cause the phenomenon of messy winding during the winding process.

[0010] Preferably, the cleaning cylinder is made of natural sponge. Here, by providing a cleaning cylinder made of natural sponge, the deionized water can be effectively absorbed and wiped, and the cleaning effect is good.

[0023] Embodiment 1

[0024] Please refer to Figures 1-5, the present utility model provides a technical solution: a cutting device for a wire cutting machine tool, including a processing table 1. A support plate 2 is fixedly installed at the top of the processing table 1. A wire paying-off roller 3 is arranged inside the support plate 2. A wire taking-up roller 4 is arranged inside the support plate 2. The wire taking-up roller 4 is fixedly installed at the output end of a motor 12. A frame plate 5 is fixedly installed on the surface of the support plate 2. A rotating plate 6 is rotatably connected to the top of the frame plate 5. The number of the rotating plate 6 and the wire guiding roller 7 is two groups and they are symmetrically distributed on the surface of the frame plate 5. The bottom end of the rotating plate 6 is rotatably connected to a wire guiding roller 7. The top end of the rotating plate 6 is rotatably connected to a connecting plate 8. When the wire guiding roller 7 is under pressure, it will drive a slider 10 to slide along a sliding rod 9 under the action of the connecting plate 8 and compress a spring 11, thereby an effective buffering effect can be obtained. A sliding rod 9 is fixedly installed inside the frame plate 5. The surface of the sliding rod 9 is slidably connected with a slider 10. The slider 10 is slidably connected with the frame plate 5. A spring 11 is sleeved on the surface of the sliding rod 9. One end of the spring 11 is fixedly installed inside the frame plate 5, and the other end of the spring 11 is fixedly installed on the side of the slider 10. A motor 12 is fixedly installed on the side of the support plate 2. When the motor 12 rotates, it will drive a pulley A 14 to rotate. Under the action of a belt 15, it will drive a pulley B 16 and a reciprocating lead screw 17 to rotate. Under the action of the thread, the reciprocating lead screw 17 will drive a wire guiding block 18 to reciprocate along a guiding rod 19. A convex plate 13 is fixedly installed at the top of the processing table 1. The output end of the motor 12 is fixedly installed with a pulley A 14. A belt 15 is sleeved on the surface of the pulley A 14. The side of the convex plate 13 is rotatably connected with a pulley B 16. The pulley B 16 is connected with the pulley A 14 through the belt 15. A reciprocating lead screw 17 is fixedly installed inside the pulley B 16. The surface of the reciprocating lead screw 17 is threadedly connected with a wire guiding block 18. The wire guiding block 18 is slidably connected with the guiding rod 19. The cutting wire will be evenly wound on the surface of the wire taking-up roller 4 under the action of the wire guiding block 18, avoiding the disorderly winding of the cutting wire. A guiding rod 19 is fixedly installed on the side of the convex plate 13.

[0025] Embodiment 2

[0026] Please refer to Figures 4-5 , a bottom plate 20 is fixedly installed on the surface of the wire guiding block 18. A rotating rod 21 is rotatably connected to the top of the bottom plate 20. A limiting groove 22 is opened inside the rotating rod 21. A clamping block 23 is arranged inside the limiting groove 22. A limiting piece 24 is fixedly installed on the back of the clamping block 23. Pull up the limiting piece 24 to drive the clamping block 23 to slide upward inside the limiting groove 22. Then rotate the limiting piece 24 by 90° and drive the limiting piece 24 to stand upright inside the rotating rod 21. Then the cleaning cylinder 25 can be pulled out from the surface of the rotating rod 21 from bottom to top. A cleaning cylinder 25 is sleeved on the surface of the rotating rod 21. The cleaning cylinder 25 is made of natural sponge. Under the action of the natural sponge, the deionized water carried on the surface of the cutting wire will be absorbed and wiped, thereby preventing the deionized water from being carried along during the winding process of the cutting wire.

[0027] Working principle: During operation, first start the motor 12 to drive the wire take-up roller 4 to rotate. At this time, under the action of the pulling force, the cutting wire on the wire pay-off roller 3 will be drawn out. During this process, the cutting wire will first come into contact with the wire guide roller 7 and conduct wire guiding work. When the wire guide roller 7 is under pressure, it will drive the wire guide roller 7 to rotate by a certain amplitude under the action of the rotating plate 6. During this process, it will drive the slider 10 to slide along the slide rod 9 under the action of the connecting plate 8 and compress the spring 11, thereby obtaining an effective buffering effect to prevent the cutting wire from being overly tightened during the wire guiding process. Then, the wire cutting work can be carried out using the cutting wire. During this process, deionized water is required. While the motor 12 is rotating, it will drive the pulley A 14 to rotate. Under the action of the belt 15, it will drive the pulley B 16 and the reciprocating lead screw 17 to rotate. Under the action of the thread, the reciprocating lead screw 17 will drive the wire guide block 18 to slide reciprocally along the guide rod 19. At this time, the used cutting wire will be evenly wound on the surface of the wire take-up roller 4 under the action of the wire guide block 18, avoiding the chaotic winding of the cutting wire. When the cutting wire passes through the wire guide block 18, it will first come into contact with the cleaning cylinder 25. Under the action of the natural sponge, it will absorb and wipe the deionized water carried on the surface of the cutting wire, thereby preventing the deionized water from being carried during the winding process of the cutting wire, which will affect the storage of the cutting wire. When it is necessary to clean the natural sponge, first pull up the limit piece 24 and drive the clamping block 23 to slide upward inside the limit groove 22. Then rotate the limit piece 24 by 90° and drive the limit piece 24 to stand upright inside the rotating rod 21. Then the cleaning cylinder 25 can be pulled out from the surface of the rotating rod 21 from bottom to top, and at this time, the cleaning cylinder 25 can be cleaned.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
