Description

Technical Field

[0001] This utility model belongs to the field of metal wire cutting technology, specifically relating to a metal wire cutting device. Background Technology

[0002] Metal wire is a type of wire-shaped metal material produced by a drawing process. It typically has high strength and hardness. The raw material for metal wire is usually quite long, and it needs to be cut to a set length during processing.

[0003] Chinese patent CN222036646U discloses a metal wire equal-length cutting device. This design includes a cutting device body, a cutting component fixedly mounted on the upper surface of the body, a second groove on the upper surface of the body, a threaded rod rotatably connected to the inner wall of the second groove, a second slider threadedly connected to the outer wall of the threaded rod, a fixing component fixedly mounted on the upper surface of the second slider, and two first grooves symmetrically formed on the upper surface of the body, with first sliders slidably connected to the inner walls of the two first grooves. A clamping component is fixedly connected to the upper surface of the first slider, the clamping component including a support frame, and an electromagnet fixedly mounted on the inner wall of the support frame. This design uses the fixing component to fix the metal wire and the clamping component to keep the metal wire taut and straight, making it more convenient to use.

[0004] When using the above solution, after the end of the metal wire is in close contact with the sensor, the clamping assembly is used to fix the metal wire. During this process, the metal wire is stationary relative to the main body of the cutting device. After the cutting is completed, the metal wire needs to be pulled again to move. The above operation steps are relatively complicated and the cutting efficiency is low. Utility Model Content

[0005] The present invention aims to provide a metal wire cutting device to solve the problems of complex operation steps and low cutting efficiency of the above-mentioned solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal wire cutting device includes a worktable, a support plate, a clamping assembly, and a driving assembly. A straightening machine is provided on one side of the worktable. The support plate is movably disposed on the top of the worktable. A mounting frame is fixedly disposed on the top of the support plate. An electric push rod is fixedly disposed on the top of the mounting frame. An upper cutter is disposed below the output end of the electric push rod. A lower cutter is disposed on the top of the support plate below the upper cutter. The clamping assembly is disposed above the support plate for clamping the metal wire. The driving assembly is disposed inside the worktable for driving the support plate to move left and right.

[0008] The principle and effects of this technical solution:

[0009] The metal wire is straightened using a straightening machine, which simultaneously pushes the wire to the right at a constant speed. After the right end of the wire passes between the upper and lower cutters, the drive assembly moves the support plate to the right, ensuring the support plate moves at the same speed as the wire. At this point, the output end of the electric push rod moves downward, fixing the wire in place with the clamping assembly. Simultaneously, the upper cutter is pushed closer to the lower cutter to cut the wire. Before the support plate reaches its rightmost position, the output end of the electric push rod moves upward, releasing the wire from the clamping assembly and moving the upper cutter above the wire. The drive assembly then resets the support plate. By adjusting the operating clearance of the electric push rod, the cutting length of the wire can be adjusted.

[0010] By setting up the above, the support plate moves at the same speed along the direction of the metal wire, and the metal wire is fixed and cut while moving continuously relative to the worktable. This solves the problems of complicated operation steps and low cutting efficiency in the above scheme, and also improves the cutting quality.

[0011] In this utility model, a relay plate is fixedly installed at the output end of the electric actuator, the upper cutter is installed below the relay plate, and sleeves are fixedly installed on both sides of the upper cutter at the bottom of the relay plate. Vertical rods are slidably inserted into the bottom of each sleeve. The clamping assembly includes upper pressure blocks fixedly installed at the bottom of the two vertical rods respectively. Lower pressure blocks are fixedly installed on the top of the support plate below the two upper pressure blocks respectively. A spring is installed inside the sleeve above the vertical rod, and the two ends of the spring are connected to the relay plate and the vertical rod respectively.

[0012] The principle and effects of this technical solution:

[0013] When the electric actuator pushes the relay plate downward, the vertical rod and the upper pressure block move downward accordingly. After the upper pressure block contacts the metal wire, the relay plate continues to move downward and compresses the spring with the vertical rod, giving the spring elasticity. The spring pushes the vertical rod and the upper pressure block to press the metal wire tightly. The relay plate continues to move downward, pushing the upper cutter closer to the lower cutter, thereby cutting the metal wire.

[0014] The above setup achieves the goal of using the lower relay plate to fix the metal wire with the clamping assembly, while simultaneously allowing the upper and lower cutters to cut the metal wire.

[0015] In this utility model, a slide groove is provided on the top of the workbench, and a first gear is rotatably provided below the slide groove. A slide rail is fixedly provided at the bottom of the support plate and is slidably embedded in the slide groove. A rack is fixedly provided on both sides of the slide rail. The drive assembly includes rotating shafts rotatably provided on both sides of the slide rail and inside the workbench. Incomplete gears and second gears are fixedly sleeved at the upper and lower ends of the two rotating shafts, respectively. A motor is fixedly provided at the bottom of the workbench. The output shaft of the motor is rotatably inserted into the workbench and is connected to the first gear. The two second gears mesh with the first gear, and the two incomplete gears mesh with the corresponding racks.

[0016] The principle and effects of this technical solution:

[0017] The motor drives the first gear to rotate clockwise and drives the two second gears to rotate counterclockwise. The two second gears drive the corresponding shafts and incomplete gears to rotate counterclockwise. One of the incomplete gears first meshes with the rack on the same side and pushes the rack and slide rail to the right. When the incomplete gear disengages from the rack on the same side, the other incomplete gear meshes with the other rack and pushes the other rack and slide rail to the left until the support plate is reset and the motor stops rotating. During the reset process of the support plate, the metal wire slides in contact with the top surface of the lower pressure block.

[0018] The above settings achieve the goal of enabling the drive component to move the support plate left and right.

[0019] In this invention, the bottom of the relay plate and the top of the support plate are symmetrically fixed with locking blocks, and the two locking blocks are symmetrically provided with locking slots on one side close to each other. The top of the upper cutter and the bottom of the lower cutter are respectively locked into the corresponding locking slots. When the upper cutter and / or the lower cutter wears out due to long-term use, the upper cutter and / or the lower cutter are removed from the locking blocks, and new upper cutters and / or lower cutters are respectively locked into the locking slots of the corresponding locking blocks. The new upper cutter and / or lower cutter are then connected to the corresponding locking blocks with bolts. Through the above arrangement, the parts of this device can be replaced, which is convenient for staff to maintain and reduces maintenance costs.

[0020] In this invention, the bottom surface of the upper pressure block is inverted V-shaped, and the top surface of the lower pressure block is V-shaped. This design prevents the metal wire from moving in the front-to-back direction during the clamping process, further improving the cutting effect.

[0021] In this invention, a protruding strip is fixedly provided on the outer side wall of the vertical rod along the vertical direction, and a limiting groove is provided on the inner side wall of the sleeve along the vertical direction. Each protruding strip is slidably embedded in the corresponding limiting groove. Through the above arrangement, the rotation of the vertical rod relative to the sleeve can be prevented, thereby preventing the upper pressure block from rotating relative to the lower pressure block.

[0022] In this invention, the top of the mounting bracket is provided with guide grooves on both sides of the electric push rod, and guide rods that slide through the corresponding guide grooves are fixedly provided at both ends of the top of the relay plate. This design prevents the relay plate from rotating during movement. Attached Figure Description

[0031] As attached Figure 1-5As shown, this utility model discloses a metal wire cutting device, including a workbench 10, a support plate 30, a clamping assembly, and a driving assembly.

[0032] In this embodiment, a relay plate 50 is fixedly installed at the output end of the electric actuator 32, and the upper cutter 41 is disposed below the relay plate 50.

The two ends of the spring 53 are connected to the relay plate 50 and the vertical rods 52, respectively.

[0033] In this embodiment, a slide groove 11 is provided on the top of the workbench 10, and a first gear 12 is rotatably provided below the slide groove 11. A slide rail 33 is fixedly provided at the bottom of the support plate 30, and the slide rail 33 is slidably embedded in the slide groove 11. A rack 34 is fixedly provided on both sides of the slide rail 33. The drive assembly includes rotating shafts 71 rotatably provided on both sides of the slide rail 33 within the workbench 10. Incomplete gears 72 and second gears 73 are fixedly sleeved at the upper and lower ends of the two rotating shafts 71, respectively. A motor 13 is fixedly provided at the bottom of the workbench 10. The output shaft of the motor 13 is rotatably inserted into the workbench 10, and the output shaft of the motor 13 is connected to the first gear 12 for transmission.

The motor 13 is electrically connected to a controller 80, and the controller 80 is used to adjust the start and stop gap of the motor 13.

[0034] In this embodiment, the bottom of the relay plate 50 and the top of the support plate 30 are respectively symmetrically fixed with locking blocks 54, and the two locking blocks 54 are symmetrically arranged with locking slots on one side close to each other.

[0035] In this embodiment, the bottom surface of the upper pressing block 61 is inverted V-shaped, and the top surface of the lower pressing block 62 is V-shaped.

[0036] In this embodiment, the outer side wall of the vertical rod 52 is fixedly provided with a protrusion 521 along the vertical direction, and the inner side wall of the sleeve 51 is provided with a limiting groove 511 along the vertical direction. Each of the protrusions 521 is slidably embedded in the corresponding limiting groove 511.

[0037] In this embodiment, the top of the mounting bracket 31 is provided with guide grooves 35 on both sides of the electric push rod 32, and the top two ends of the relay plate 50 are respectively fixedly provided with guide rods 55 that slide through the corresponding guide grooves 35.

[0038] The specific implementation process is as follows:

[0039] The straightening machine 20 straightens the metal wire 100 while simultaneously pushing the metal wire 100 to the right at a constant speed. After the right end of the metal wire 100 passes between the upper cutter 41 and the lower cutter 42, the drive assembly moves the support plate 30 to the right, and the moving speed of the support plate 30 is the same as the moving speed of the metal wire 100. At this time, the output end of the electric push rod 32 moves down, so that the clamping assembly fixes the metal wire 100. At the same time, the upper cutter 41 is pushed closer to the lower cutter 42 to cut the metal wire 100. Before the support plate 30 moves to the far right, the output end of the electric push rod 32 moves up, so that the clamping assembly releases the metal wire 100 and the upper cutter 41 moves above the metal wire 100. Then the drive assembly drives the support plate 30 to reset. By adjusting the operating gap of the electric push rod 32, the cutting length of the metal wire 100 is adjusted.

[0040] When the electric actuator 32 pushes the relay plate 50 downward, the vertical rod 52 and the upper pressure block 61 move downward accordingly. After the upper pressure block 61 contacts the metal wire 100, the relay plate 50 continues to move downward and compresses the spring 53 with the vertical rod 52, so that the spring 53 has elasticity. The spring 53 pushes the vertical rod 52 and the upper pressure block 61 to press the metal wire 100. The relay plate 50 continues to move downward, pushing the upper cutter 41 close to the lower cutter 42, thereby cutting the metal wire 100.

[0041] Motor 13 drives the first gear 12 to rotate clockwise and drives the two second gears 73 to rotate counterclockwise. The two second gears 73 respectively drive the corresponding rotating shaft 71 and the incomplete gear 72 to rotate counterclockwise. One of the incomplete gears 72 first meshes with the rack 34 on the same side and pushes the rack 34 and the slide rail 33 to the right. When the incomplete gear 72 disengages from the rack 34 on the same side, the other incomplete gear 72 meshes with the other rack 34 and pushes the other rack 34 and the slide rail 33 to the left until the support plate 30 is reset. Motor 13 stops rotating. During the reset process of the support plate 30, the metal wire 100 slides in contact with the top surface of the lower pressure block 62.
