Description

Technical Field

[0001] This invention relates to the field of wire cutting technology, and more particularly to a metal wire processing and cutting device. Background Technology

[0002] During the manufacturing process, metal guide wires need to be cut to an equal quantity to ensure their standardized use. Current methods use cutting shears to cut the metal guide wires, but due to the nature of mass production, these shears present the following problems: 1. One end of the guide wire is wound on the take-up roller, and the other end is pulled forward by the traction mechanism. When it moves to the cutting point of the guide wire, it stops moving and is cut by the moving cutter. When the metal guide wire breaks during the cutting, the unfixed end is prone to swinging and is inconvenient to collect. Second, during the cutting process, the traction mechanism will stop running before cutting, which affects production efficiency. Third, after a section of the metal guide wire is cut, the traction mechanism needs to re-fix the metal guide wire and then pull it to cut the next section, which affects production efficiency. To address the above problems, we propose a metal wire processing and cutting device. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a metal guide wire processing and cutting device. Two sets of extrusion plates, one and two, are used to fix the metal guide wire, avoiding the adverse effects of the wire breaking and swaying during cutting. This facilitates collection and eliminates the need to stop traction and re-fix the wire. A conveyor belt transports the quantitative fixing mechanism, which is arranged in an array to ensure quantitative cutting and improve cutting efficiency.

[0004] The present invention provides a metal guide wire processing and cutting device, including a processing table, a U-shaped frame plate fixedly connected to the processing table, a traction quantitative cutting component on the U-shaped frame plate, two sets of traction quantitative cutting components symmetrically arranged with the center position of the processing table as a reference, and a metal guide wire traction channel is formed between the two sets of traction quantitative cutting components. The traction quantitative cutting assembly includes a conveying mechanism, which includes a conveying shaft and a conveyor belt. Two sets of conveying shafts are symmetrically arranged with the center position of the processing table as a reference. A drive motor is fixedly connected to the bottom end of the processing table. The output end of the drive motor is coaxially fixedly connected to one of the conveying shafts. Conveyor wheels are coaxially fixedly sleeved on the conveying shafts. Two sets of conveyor wheels are arranged above and below. The conveyor belt is wound around the two conveyor wheels that are symmetrically arranged with the center position of the processing table as a reference.

[0005] The traction quantitative cutting assembly also includes a quantitative fixing mechanism. The quantitative fixing mechanism is arranged in a curved array with multiple sets. The quantitative fixing mechanism includes a positioning block, a first extrusion plate, and a second extrusion plate. The two ends of the positioning block are fixedly connected to the upper and lower sets of conveyor belts, respectively. The first extrusion plate is elastically and movably connected to the positioning block. A rotating plate is movably connected to the positioning block. The rotating plate is connected to the end face of the first extrusion plate. An extrusion rod is elastically connected to the rotating plate. The second extrusion plate is fixedly connected to the extrusion rod. A cutting shear is fixedly connected to the rotating plate. The cutting shear is located between adjacent first and second extrusion plates.

[0006] The traction quantitative cutting assembly also includes a support plate, which is fixedly connected to the processing table. The conveyor shaft extends movably through the support plate. A protrusion is provided on the side end face of the support plate. A movable wheel is rotatably connected to the rotating wheel plate. The movable wheel travels on the side end face of the support plate. When the movable wheel reaches the protrusion of the support plate, the extrusion plate one, extrusion plate two and positioning block are relatively displaced. The two sets of extrusion plates one and two respectively approach each other to extrude the metal guide wire. An arc-shaped push plate is fixedly connected to the support plate. When the extrusion rod moves into the arc-shaped push plate, the arc-shaped push plate pushes the extrusion rod to move. The two sets of opposing extrusion plates two move away from each other and release the metal guide wire. When the two sets of opposing extrusion plates two move away from each other and release the metal guide wire in the direction of movement, the extrusion plate one in the quantitative fixing mechanism at the front end releases the metal guide wire.

[0007] Beneficial effects of the present invention: The present invention provides a metal wire processing and cutting device: 1. When the moving wheel moves to the protrusion of the support plate, the moving wheel is pushed to move away from the support plate. The moving wheel drives the rotating plate, extrusion plate 1, extrusion plate 2, and cutting shears to move towards the center of the processing table. The two opposing extrusion plates 1 squeeze and fix the metal guide wire, the two opposing extrusion plates 2 squeeze and fix the metal guide wire, and the two cutting shears cut the metal guide wire, thus completing the cutting and fixing of the metal guide wire. Second, the conveyor belt drives the quantitative fixing mechanism on it to move, which in turn drives the extrusion plate one and extrusion plate two inside the quantitative fixing mechanism to move, continuously conveying the metal guide wire. 3. When the arc-shaped push block enters the arc-shaped push plate, the arc-shaped push plate pushes the arc-shaped push block to move, and the two sets of opposing extrusion plates move away from each other, releasing the metal guide wire. At the same time, the adjacent front moving wheels separate from the protrusion. Since the extrusion plate is elastically connected to the positioning block, without the support of the protrusion, under the elastic extrusion force, the extrusion plate moves towards the positioning block, and the cut metal guide wire is put down, completing the cutting. Fourth, since the quantitative fixing mechanism is arranged in an array on the conveyor belt, the distance between two adjacent quantitative fixing mechanisms in the horizontal movement direction is equal, ensuring the uniformity of cutting; V. The extrusion plate 1 in the quantitative fixing mechanism and the extrusion plate 2 in the adjacent quantitative fixing mechanism simultaneously loosen the cut metal guide wire, which facilitates the collection of the cut metal guide wire. VI. After the extrusion plate one and extrusion plate two in the same quantitative fixing mechanism fix the metal guide wire, they do not release the metal guide wire at the same time. Therefore, the metal guide wire can be continuously pulled. Attached Figure Description

[0009] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Similarly, these embodiments are provided so that the disclosure of the present invention may be more thorough and complete.

[0010] according to Figures 1-7The metal wire processing and cutting device shown includes a processing table 1, a feeding hole 21 on the processing table 1, a U-shaped frame plate 2 fixedly connected to the processing table 1, a traction quantitative cutting component 3 on the U-shaped frame plate 2, and two sets of traction quantitative cutting components 3 symmetrically arranged with the center position of the processing table 1 as a reference. The traction quantitative cutting assembly 3 includes a conveying mechanism 4, which includes a conveying shaft 6 and a conveyor belt 7. Two sets of conveying shafts 6 are symmetrically arranged with the center position of the processing table 1 as a reference. A drive motor 15 is fixedly connected to the bottom end of the processing table 1. The output end of the drive motor 15 is coaxially fixedly connected to one of the conveying shafts 6. A conveying wheel 8 is coaxially fixedly sleeved on the conveying shaft 6. Two sets of conveying wheels 8 are arranged above and below. The conveyor belt 7 is wound around the two conveying wheels 8 symmetrically arranged with the center position of the processing table 1 as a reference. When the drive motor 15 is started, the output end of the drive motor 15 drives the conveying shaft 6 to rotate. The conveying shaft 6 drives the conveying wheel 8 to rotate. The rotating conveying wheel 8 drives the conveyor belt 7 to rotate.

[0011] The traction quantitative cutting assembly 3 also includes a quantitative fixing mechanism 5. Multiple sets of quantitative fixing mechanisms 5 are arranged in an array along the conveyor belt 7. The quantitative fixing mechanism 5 includes a positioning block 9, a first extrusion plate 10, and a second extrusion plate 11. The two ends of the positioning block 9 are respectively fixedly connected to the upper and lower sets of conveyor belts 7. The first extrusion plate 10 is elastically axially slidably connected to the positioning block 9. A rotating wheel plate 12 is movably connected to the positioning block 9. The rotating wheel plate 12 is connected to the end face of the first extrusion plate 10. An extrusion rod 13 is elastically connected to the rotating wheel plate 12. The second extrusion plate 11 is fixedly connected to the extrusion rod 13. A cutter 14 is fixedly connected to the rotating wheel plate 12. The cutter 14 is located between adjacent first extrusion plate 10 and second extrusion plate 11. When the conveyor belt 7 is conveyed in a ring, it drives the quantitative fixing mechanism 5 and the cutter 14 to move. A metal guide wire traction channel is formed between the two sets of traction quantitative cutting assemblies 3 on their respective sides. The metal guide wire enters from this traction channel and is clamped and fixed by the quantitative fixing mechanism 5 in the corresponding position of the two sets of traction quantitative cutting assemblies 3.

[0012] The traction quantitative cutting assembly 3 also includes a support plate 16, which is fixedly connected to the processing table 1. The conveyor shaft 6 extends movably through the support plate 16. The two ends of the support plate 16 are semi-circular structures. A protrusion 18 is provided on the side end face of the support plate 16. The length of the protrusion 18 is greater than the distance between two adjacent quantitative fixing mechanisms 5. A movable wheel 17 is rotatably connected to the rotary wheel plate 12. The movable wheel 17 travels on the side end face of the support plate 16. When the movable wheel 17 travels to the protrusion 18 of the support plate 16, the extrusion plate 10, the extrusion plate 11 and the positioning block 9 undergo relative displacement, and the two sets of traction quantitative... In the cutting assembly 3, two sets of extrusion plates 10 and 11, which are positioned opposite each other, approach each other to extrude the metal guide wire. An arc-shaped push plate 19 is fixedly connected to the support plate 16, and an arc-shaped push block 20 is fixedly connected to the extrusion rod 13. When the arc-shaped push block 20 enters the arc-shaped push plate 19, the arc-shaped push plate 19 pushes the arc-shaped push block 20 to move, and the two sets of opposing extrusion plates 11 move away from each other, releasing the metal guide wire. When the two sets of opposing extrusion plates 11 move away from each other and release the metal guide wire in the direction of movement, the extrusion plate 10 in the quantitative fixing mechanism 5 at the front end releases the metal guide wire.

[0013] principle: Conveying: Drive motor 15 starts, and the output end of drive motor 15 drives conveyor shaft 6 to rotate. Conveyor shaft 6 drives conveyor wheel 8 to rotate. The rotating conveyor wheel 8 drives conveyor belt 7 to rotate. When conveyor belt 7 is conveying, it drives quantitative fixing mechanism 5 on it to move. The end of metal guide wire passes through the traction channel between conveyor belt 7 in the two sets of traction quantitative cutting components 3 and enters the two sets of quantitative fixing mechanisms 5 corresponding to the position. The two sides of the end of metal guide wire are clamped by quantitative fixing mechanisms 5 corresponding to the position in the two sets of traction quantitative cutting components 3. Quantitative fixing mechanism 5 clamps metal guide wire through extrusion plate 10 and extrusion plate 21 and drives metal guide wire to move. Quantitative cutting: When the moving wheel 17 moves to the protrusion 18 of the support plate 16, the moving wheel 17 is pushed to move away from the support plate 16. The moving wheel 17 drives the rotating plate 12, the first extrusion plate 10, the second extrusion plate 11, and the cutting shears 14 to move towards the center of the processing table 1. The first extrusion plate 10 in the two sets of traction quantitative cutting components 3, which are in opposite positions, extrudes and fixes the metal guide wire. The second extrusion plate 11 in the two sets of traction quantitative cutting components 3, which are in opposite positions, extrudes and fixes the metal guide wire. The two cutting shears 14 in the two sets of traction quantitative cutting components 3, which are in opposite positions, cut the metal guide wire, thus completing the cutting and fixing of the metal guide wire.

[0014] As the conveyor belt 7 continues to transport the metal wire, when the arc-shaped push block 20 enters the arc-shaped push plate 19, the arc-shaped push plate 19 pushes the arc-shaped push block 20 to move. The two sets of traction quantitative cutting components 3, with oppositely positioned extrusion plates 11, move away from each other, releasing the metal guide wire. At the same time, the adjacent front moving wheel 17 separates from the protrusion 18. Since the extrusion plate 10 is elastically connected to the positioning block 9, without the support of the protrusion 18, under the elastic extrusion force, the extrusion plate 10 moves towards the positioning block 9, and the cut metal guide wire is put down, completing the cutting. The falling metal guide wire passes through the discharge hole 21 on the processing table 1 and falls into the external collection frame for collection.

[0015] As the conveyor belt 7 continues to transport the metal wire, the continuous processing and cutting of the metal wire is completed. Since the quantitative fixing mechanism 5 is arranged in an array on the conveyor belt 7, the distance between two adjacent quantitative fixing mechanisms 5 in the horizontal movement direction is equal, ensuring the uniformity of the cutting.

Any person skilled in the art may make various modifications and alterations without departing from the spirit and scope of the present invention.
