Description

Technical Field

[0001] This utility model relates to the field of metal wire cutting technology, specifically a cutting device based on repeated pulling of metal wire. Background Technology

[0002] Metal wire drawing is a plastic forming process that uses external force to pull metal raw materials out of the die hole of a drawing die to obtain a product of the required size. Metal wire can be processed through multiple drawing processes, including different stages such as rough drawing, medium drawing, fine drawing, and micro-drawing. The drawing process produces metal wire with a uniform interface, high surface smoothness, and high strength and hardness. In addition, the drawing process can also improve the tensile strength and toughness of the metal wire, giving it better mechanical properties and corrosion resistance. Since the metal wire is very long after drawing, it needs to be cut by a cutting device according to processing requirements.

[0003] Currently, existing cutting devices typically use a straightening mechanism to feed the metal wire, and then a shearing mechanism to cut the metal wire. However, the shearing mechanism can only cut a section of the metal wire at a time. Since the straightening mechanism stops working during the cutting process, and only one section can be cut at a time, the cutting efficiency of the metal wire is low. Moreover, it is quite troublesome to adjust the cutting length of the metal wire in existing cutting devices. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device based on multiple pulls of metal wire to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cutting device based on multiple pulls of metal wire includes an operating table with a through hole on its top surface. A shearing mechanism is mounted on the top surface of the operating table. Multiple conveying mechanisms are detachably connected to the top surface of the operating table. A sliding hole is formed through one side of the top surface of the operating table. The shearing mechanism includes four double-headed cylinders fixed to the four corners of the top surface of the operating table. Each of the four double-headed cylinders, located in the same plane, has a pressure plate fixedly connected to its output end. A sliding hole is formed through the top surface of the pressure plate. Multiple rectangular sleeves are slidably connected inside the sliding hole. L-shaped plates are slidably connected to both ends of each rectangular sleeve. Limiting blocks are fixedly connected to the opposite sides of two L-shaped plates, slidably connected to the corresponding sliding holes. Shearing blades are fixedly connected to the opposite sides of two limiting blocks. The conveying mechanism includes two symmetrical support plates. A cross groove is formed through the top of each support plate. Two parallel cross blocks are slidably connected inside the cross groove. A round rod is rotatably connected between two cross blocks at opposite positions. Rollers are fixedly connected to the outer wall of the round rod.

[0007] Furthermore, a rack two is fixedly connected to one side of the top surface of the pressure plate located above the operating table, and a stop plate is fixedly connected to one end of the L-shaped plate two located above the rectangular sleeve.

[0008] Preferably, two symmetrical springs are fixedly connected between the rack three and the corresponding abutment plate, and the length of the slide plate is greater than the depth of the sleeve hole.

[0009] Furthermore, both ends of the operating platform are fixedly connected to connecting plates. A motor is fixedly connected to the top surface of one of the connecting plates. A pulley is fixedly connected to the output end of the motor. An L-shaped plate is fixedly connected to the top surface of the connecting plate. A worm gear is rotatably connected between the two L-shaped plates. A pulley is fixedly connected to one end of the outer wall of the worm gear, which is driven by a belt through the pulley.

[0011] Preferably, the top surface of the operating table is provided with sliding grooves on both sides of the through hole, and the bottom end of the support plate is fixedly connected with a slider that is slidably connected to the sliding groove at the corresponding position.

[0012] Furthermore, the bottom surface of the operating table is fixedly connected to a cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 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.

[0023] Please see Figures 1-5 In this embodiment of the present invention, a cutting device based on multiple pulls of metal wire includes an operating table 1. A through hole is provided on the top surface of the operating table 1. A shearing mechanism 2 is provided on the top surface of the operating table 1. Multiple conveying mechanisms 3 are detachably connected to the top surface of the operating table 1. A sliding hole 11 is provided on one side of the top surface of the operating table 1. The shearing mechanism 2 includes four double-headed cylinders 21, each fixedly connected to one of the four corners of the top surface of the operating table 1. Pressure plates 22 are fixedly connected to the output ends of the four double-headed cylinders 21 located in the same plane. A sliding hole 221 is provided on the top surface of the pressure plate 22. Multiple rectangular sleeves are slidably connected inside the sliding hole 11. 23. Both ends of the rectangular sleeve 23 are slidably connected to L-shaped plates 231. On the opposite side of the two L-shaped plates 231, there are limit blocks that are slidably connected to the corresponding sliding holes 221. On the opposite side of the two limit blocks, there are shearing blades 24. The conveying mechanism 3 includes two symmetrical support plates 31. The top of the support plate 31 is provided with a cross groove 311. Two parallel cross blocks 32 are slidably connected inside the cross groove 311. A round rod is rotatably connected between the two cross blocks 32 at opposite positions. A roller 33 is fixedly connected to the outer wall of the round rod. The bottom surface of the operating table 1 is fixedly connected to the cabinet 18.

[0024] Specifically, firstly, the cutting length of the metal wire is determined according to production needs. Then, multiple conveying mechanisms 3 are installed on both sides of the top surface of the operating table 1, and the distance between two adjacent conveying mechanisms 3 is adjusted so that the two cutting points of the metal wire are located between the two adjacent conveying mechanisms 3. Then, the metal wire passes between multiple rollers 33, and the metal wire is conveyed by the rotation of two rollers 33 at relative positions until the head of the metal wire passes between the two rollers 33 at the last position. Then, the multiple rollers 33 stop rotating. At the same time, the spacing of multiple shearing blades 24 at the same height is adjusted according to the cutting length of the metal wire. Then, by activating four double-headed cylinders 21, two pressure plates 22 are brought closer together. The two pressure plates 22 bring the multiple shearing blades 24 located above and below closer together until the multiple shearing blades 24 located above and below cut the metal wire. The cut metal wire falls into the cabinet 18 through the through hole under its own gravity between the two adjacent support plates 31. Since the two cutting points of the metal wire are located between the two adjacent support plates 31, the cut metal wire clamped between the two rollers 33 at the same position will not fall. Then, the metal wire can be transported again by the rotation of multiple rollers 33. At this time, the head of the transported metal wire will push the clamped metal wire out from between the two rollers 33 at the corresponding position and fall into the cabinet 18 under the action of the transport force. Multiple shearing blades 24 can cut the metal wire into multiple segments at the same time, thereby improving the cutting efficiency of the metal wire. Moreover, the rotation of multiple rollers 33 can transport the metal wire and clamp and fix it. Under the limit of the support plate 31, the metal wire is tightened and straightened, which can prevent the metal wire from bending and causing cutting errors during the cutting process. Example

[0025] like Figure 3-4 As shown, in this embodiment, a rack 222 is fixedly connected to one side of the top surface of the pressure plate 22 located above the operating table 1, and a stop plate 27 is fixedly connected to one end of the L-shaped plate 231 located above the rectangular sleeve 23. A sleeve hole 28 is opened through one side of the stop plate, and a sliding plate 25 is slidably connected inside the sleeve hole. A rack 26 that meshes with the rack 222 is fixedly connected to one end of the sliding plate 25. Two symmetrical springs 261 are fixedly connected between the rack 26 and the stop plate at the corresponding position. The length of the sliding plate 25 is greater than the depth of the sleeve hole.

[0026] In this embodiment, by pulling the slide plate 25, the rack 3 26 can be disengaged from the rack 222, thereby moving the two shearing blades 24 at the corresponding positions. This allows the operator to adjust the spacing between the two adjacent shearing blades 24 according to the cutting length of the metal wire, enabling the metal wire to be cut into multiple segments at the same time, thus improving the cutting efficiency of the metal wire. Example

[0027] Based on Example 1, in order to prevent multiple shearing blades 24 from bending the metal wire and causing shearing errors.

[0028] like Figure 2 and Figure 5 As shown, in this embodiment, both ends of the operating platform 1 are fixedly connected to connecting plates 12. A motor 13 is fixedly connected to the top surface of one of the connecting plates 12. A pulley 131 is fixedly connected to the output end of the motor 13. An L-shaped plate 14 is fixedly connected to the top surface of the connecting plate 12. A worm gear 15 is rotatably connected between the two L-shaped plates 14. One end of the outer wall of the worm gear 15 is fixedly connected to a pulley 151 that is driven by a belt through the pulley 131. One end of the round rod passes through a cross block 32 near the worm gear 15 and is fixedly connected to a worm wheel 34 that meshes with the worm gear 15. Opposite sides of the cross groove 311 away from the worm gear 15 are rotatably connected to... A bidirectional screw 35 is screwed through and engaged with two cross blocks 32 at corresponding positions. A rack 16 is fixedly connected to one side of the top surface of the operating table 1. A rectangular groove 312 is opened on one side of one of the support plates 31. A slide rod is fixedly connected between the two opposite sides inside the rectangular groove 312. A slider 2 is slidably connected to the outer wall of the slide rod. A rack 4 36 that meshes with the rack 16 is fixedly connected to one side of the slider 2. A spring 2 37 is fixedly connected between the slider 2 and the rectangular groove 312. A slide groove 17 is opened on both sides of the top surface of the operating table 1 and located at the through hole. A slider 313 that is slidably connected to the slide groove 17 at the corresponding position is fixedly connected to the bottom end of the support plate 31.

[0029] In this embodiment, the rotation of the bidirectional screw 35 causes the two cross blocks 32 at corresponding positions to move in opposite directions (the cross groove 311 can be pre-cut, a metal block placed in the cross groove 311, and a fixing block welded to each side of the metal block to form a cross block 32). This causes the two rollers 33 at corresponding positions to move in opposite directions. When the two rollers 33 at opposite positions approach each other, they can clamp the metal wire. Then, the motor 13 drives the pulley 131 to rotate the pulley 151, which in turn rotates the worm 15. Since multiple worm gears 34 mesh with the worm 15, and the two worm gears 34 at opposite positions are distributed vertically, the rotating worm 15 can cause the multiple worm gears 34 to drive the two rollers 33 at corresponding positions to rotate, and the two rollers 33 rotate in opposite directions. Two rollers 33 at relative positions clamp the metal wire, so the rotating rollers 33 can transport the metal wire. When it is necessary to adjust the distance between the two adjacent support plates 31, the rack 4 36 is moved upward, so that the rack 4 36 is disengaged from the rack 16. At this time, the support plate 31 can be moved to adjust the distance between the two adjacent support plates 31, so that the two shearing points of the metal wire are located between the two adjacent support plates 31. When it is necessary to remove part of the support plate 31 from the operating table 1, the two rollers 33 at the corresponding positions are moved away from each other by rotating the bidirectional screw 35 in the opposite direction, and the rack 4 36 at the corresponding position is disengaged from the rack 16. Then the support plate 31 at the corresponding position is slid until the support plate 31 slides out from one end of the operating table 1. The number of support plates 31 can be increased or decreased as needed.
