Description

Technical Field

[0001] This utility model relates to the field of wire cutting machine tool technology, specifically to a molybdenum wire adjustment and winding device. Background Technology

[0002] Wire EDM machines fall under the category of electrical discharge machining. They use the high-speed rotation of molybdenum or tungsten-molybdenum wires to discharge and cut conductive plates or workpieces. The basic physical principle is that free positive ions and electrons accumulate in the field, quickly forming an ionized conductive channel, thereby achieving the cutting and processing of the workpiece.

[0003] The molybdenum wire cut by the wire EDM machine has a large span during operation. As the molybdenum wire passes through the winding device, it is subject to its own tension, which may cause the wire to become loose and its length to increase. This directly affects the tension and tensile strength of the molybdenum wire. Once the molybdenum wire becomes loose and the tension decreases, it will directly affect the surface finish and machining accuracy of the processed parts. Utility Model Content

[0004] The purpose of this invention is to provide a molybdenum wire adjusting winding device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a molybdenum wire adjusting winding device, including a frame, a drive wheel, a positioning wheel, a molybdenum wire body, and an adjusting mechanism. The adjusting mechanism includes an adjusting plate, a first adjusting wheel, a second adjusting wheel, a tension gauge, and a driving assembly. A rotating shaft is fixedly connected to the inner wall of the frame. The driving assembly is located at one end of the rotating shaft. The adjusting plate is fixedly connected to one end of the rotating shaft. Two fixed shafts are fixedly connected to one end of the adjusting plate. The first adjusting wheel and the second adjusting wheel are rotatably connected to one end of the two fixed shafts, respectively. The molybdenum wire body is wound around the first adjusting wheel and the second adjusting wheel in an S-shaped path. The tension gauge is mounted on the frame through a mounting assembly.

[0006] In a preferred embodiment, the molybdenum wire body passes sequentially through the measuring wheel at the lower end of the tension meter and two symmetrically distributed guide wheels.

[0007] In a preferred embodiment: the number of positioning wheels is several, both the drive wheel and the positioning wheel are mounted on the frame, and the molybdenum wire body is sequentially wound around the drive wheel and the positioning wheel.

[0008] In a preferred embodiment: the drive assembly includes a drive gear, a drive rack, and a drive cylinder. The drive gear is fixedly installed on the outer wall of the rotating shaft. The lower end of the drive gear is meshed with the drive rack. The lower end of the drive rack is integrally formed with a drive plate. One end of the drive plate is slidably connected to the inner wall of the frame. The output end of the drive cylinder is fixedly installed on the drive plate. The drive cylinder is installed inside the frame.

[0009] In a preferred embodiment, the tension gauge establishes a control connection with the drive cylinder via a controller.

[0010] In a preferred embodiment: the controller and the tension gauge are electrically connected via a first wire, and the drive cylinder and the controller are electrically connected via a second wire.

[0011] In a preferred embodiment: the mounting assembly includes mounting plates and fastening bolts, and two symmetrically distributed mounting plates are fixedly connected to both sides of the tension meter. One end of the fastening bolt passes through the mounting plate and is threaded to the inner wall of the frame.

[0012] In a preferred embodiment, positioning grooves are provided on the walls of the drive wheel, the positioning wheel, the first adjusting wheel, and the second adjusting wheel.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: This invention uses a tension meter to monitor the tension of the molybdenum wire body in real time. When the tension is insufficient, the tension meter transmits a signal to the controller, which then controls the drive cylinder to adjust the positions of the first and second adjusting wheels. Since the molybdenum wire body is wound in an S-shape around the first and second adjusting wheels, the change in the position of the adjusting wheels can change the tension of the molybdenum wire body, achieving the effect of automatically adjusting the tension of the molybdenum wire. This ensures the stability of the molybdenum wire tension, thereby guaranteeing the surface finish and machining accuracy of the processed parts. By adjusting the tension in real time, the problem of the molybdenum wire lengthening due to long-term slack or excessive tightness can be avoided, reducing the deformation of the molybdenum wire caused by insufficient tension, thus ensuring the tensile strength of the molybdenum wire and reducing the risk of breakage. At the same time, the tension meter can be easily installed on the frame through the mounting assembly, facilitating later maintenance and replacement. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3 This utility model provides a technical solution: a molybdenum wire adjusting winding device, including a frame 1, a drive wheel 2, a positioning wheel 3, a molybdenum wire body 4, and an adjusting mechanism. The adjusting mechanism includes an adjusting plate 5, a first adjusting wheel 6, a second adjusting wheel 7, a tension meter 8, and a driving assembly. A rotating shaft 9 is fixedly connected to the inner wall of the frame 1. The driving assembly is located at one end of the rotating shaft 9. An adjusting plate 5 is fixedly connected to one end of the rotating shaft 9. Two fixed shafts 10 are fixedly connected to one end of the adjusting plate 5. The first adjusting wheel 6 and the second adjusting wheel 7 are rotatably connected to one end of the two fixed shafts 10, respectively. The molybdenum wire body 4 is wound around the first adjusting wheel 6 and the second adjusting wheel 7 in an S-shaped path. Positioning grooves for the movement of the molybdenum wire body 4 are opened on the walls of the drive wheel 2, the positioning wheel 3, the first adjusting wheel 6, and the second adjusting wheel 7. The tension meter 8 is mounted on the frame 1 through an mounting assembly.

[0017] During operation, the tension gauge 8 monitors the tension of the molybdenum wire body 4 in real time through the measuring wheel 80. When the tension is lower than the set value, the tension gauge 8 transmits the signal to the controller 15 through the first wire. The controller 15 controls the extension of the drive cylinder 13 through the second wire. The drive cylinder 13 pushes the drive plate 14 to move. The drive plate 14 drives the drive rack 12 to move. The drive rack 12 meshes with the drive gear 11, causing the drive gear 11 and the rotating shaft 9 to rotate counterclockwise. The rotating shaft 9 drives the adjusting plate 5 to rotate. The adjusting plate 5 drives the first adjusting wheel 6 and the second adjusting wheel 7 to move. Since the molybdenum wire body 4 is wrapped around the first adjusting wheel 6 and the second adjusting wheel 7 in an S-shape, the change in the position of the adjusting wheel causes the molybdenum wire body 4 to tighten until the tension reaches the set value. The drive cylinder 13 then stops. When the tension is higher than the set value, the same principle applies. The drive cylinder 13 begins to shorten, and the drive gear 11 drives the rotating shaft 9 to start rotating clockwise, thereby relaxing the molybdenum wire body 4 until the set value is reached.

[0018] The molybdenum wire body 4 passes sequentially through the measuring wheel 80 and two symmetrically distributed guide wheels 81 at the lower end of the tension meter 8. The tension meter 8 monitors the tension of the molybdenum wire body 4 in real time through the measuring wheel 80.

[0019] There are several positioning wheels 3. Both the driving wheel 2 and the positioning wheel 3 are located on the frame 1. The molybdenum wire body 4 is wound around the driving wheel 2 and the positioning wheel 3 in sequence.

[0020] The drive assembly includes a drive gear 11, a drive rack 12, and a drive cylinder 13. The drive gear 11 is fixedly installed on the outer wall of the rotating shaft 9. The lower end of the drive gear 11 is meshed with the drive rack 12. The lower end of the drive rack 12 is integrally formed with a drive plate 14. One end of the drive plate 14 is slidably connected to the inner wall of the frame 1. The output end of the drive cylinder 13 is fixedly installed on the drive plate 14. The drive cylinder 13 is installed inside the frame 1.

[0021] The tension meter 8 establishes a control connection with the drive cylinder 13 through the controller 15.

[0022] The controller 15 is electrically connected to the tension gauge 8 through the first wire, and the drive cylinder 13 is electrically connected to the controller 15 through the second wire.

[0023] The mounting assembly includes mounting plates 16 and fastening bolts 17. Two symmetrically distributed mounting plates 16 are fixedly connected to both sides of the tension meter 8. One end of the fastening bolt 17 passes through the mounting plate 16 and is threaded to the inner wall of the frame 1.

[0024] Finally, it should be noted that: all parts not described in this utility model are the same as or can be implemented using existing technology. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
