Description

Technical Field

[0001] This invention relates to the field of wire and cable technology, and in particular to a cutting device for wire and cable manufacturing. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize electromagnetic energy conversion. They consist of multiple insulated wire cores and are wrapped with an outer sheath. During the manufacturing process, wires and cables need to be cut. Existing cutting devices use cylinders to drive the cutting blades to complete the cutting operation. However, during the cutting process, due to the properties of the outer sheath (rubber has a certain degree of tensile strength), it is easy to twist and deform. Therefore, we propose a cutting device for wire and cable manufacturing to solve the above problems. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Reference Figures 1-8 A cutting device for manufacturing wires and cables includes a wire and cable 22 and a disc 1 with a support frame. The disc 1 has a circular hole 21 that mates with the wire and cable 22. A driving component is installed on the disc 1, and an external toothed ring 9 that mates with the driving component is rotatably installed on the disc 1. The support frame includes a vertical rod 2 and a base 3. The vertical rod 2 is fixedly installed at the lower end of the disc 1, and the base 3 is fixedly installed at the lower end of the vertical rod 2. The base 3 is shown as a strip in the figure, but it can also be circular in a specific configuration, used to provide support for the whole.

[0032] The driving components include a servo motor 4, a rotating shaft 5, and a rotating gear 13. The servo motor 4 is fixedly installed on one side of the disk 1. The rotating shaft 5 is fixedly installed on the driving end of the servo motor 4. The rotating shaft 5 rotates through the disk 1 and is fixedly installed with the rotating gear 13, which meshes with the external gear ring 9. A motor cover (with a heat dissipation mesh plate) can be fixedly installed on one side of the disk 1 to isolate the servo motor 4. While protecting the servo motor 4, the noise can be reduced. Sound-absorbing sponge can also be placed inside the motor cover to further increase the noise reduction effect.

[0033] An annular groove 7 is provided on the disk 1. A plurality of stepped sliders 8 that cooperate with the annular groove 7 are fixedly installed on the side of the external toothed ring 9 near the disk 1. The annular groove 7 is stepped. Through the cooperation of the annular groove 7 and the stepped sliders 8, the external toothed ring 9 can rotate relative to the disk 1, and at the same time, one side of the external toothed ring 9 is in contact with one side of the disk 1.

[0034] A support frame 6 is fixedly installed on the disc 1, and one end of the rotating shaft 5 is rotatably installed on the support frame 6. The support frame 6 consists of a circular vertical rod, a strip short rod, and a circular block. One end of the circular vertical rod is fixedly installed on the disc 1, and the other end is fixedly installed with the strip short rod. One end of the strip short rod is fixedly installed with the circular block, and one end of the rotating shaft 5 is rotatably installed on the circular block.

[0035] Reference Figures 1-8 An annular mounting base 10 is fixedly installed on the side of the external toothed ring 9 away from the disc 1. A bidirectional screw 14 is rotatably mounted on the annular mounting base 10, and a rotating component is installed between the bidirectional screw 14 and the disc 1. The lower end of the bidirectional screw 14 is configured with bidirectional threads (the upper end is configured with a smooth thread). A lifting frame rod is threadedly installed on the lower end of the bidirectional screw 14. A mounting plate 19 is fixedly installed on the lower end of the lifting frame rod. A piercing blade 20 that cooperates with the wire and cable 22 is fixedly installed on the lower surface of the mounting plate 19. The function of the piercing blade 20 is to be able to insert into the outer sheath of the wire and cable 22 when it moves downward, and then to strip the wire and cable 22 by rotating with the piercing blade 20.

[0036] The rotating component is configured to drive the external gear ring 9 to rotate, and the rotation of the external gear ring 9 will drive the annular mounting base 10 to rotate. The rotating component includes a support rod 11, a gear ring 12, a one-way bearing 15, and a lifting gear 16. A gear ring 12 is fixedly mounted on the disc 1 by multiple support rods 11. The part of the bidirectional screw 14 located on the annular mounting base 10 is equipped with a lifting gear 16 by a one-way bearing 15, and the lifting gear 16 meshes with the gear ring 12.

[0037] The lifting frame is designed to drive the mounting plate 19 and the piercing bar 20 to rotate relative to the wire and cable 22 when the bidirectional screw 14 rotates. The lifting frame includes a lifting block 17 and a frame 18. The lower end of the bidirectional screw 14 is threaded with the lifting block 17. Multiple frames 18 are fixedly installed on the outside of the lifting block 17, and the lower end of the frame 18 is fixedly installed on the mounting plate 19. The frame 18 is composed of a block and a rod. One end of the block is fixedly connected to the lifting block 17, and the lower end of the rod is fixed on the mounting plate 19.

[0038] Reference Figures 1-8 An arc-shaped hole 23 is provided on the annular mounting base 10. A cutting table 24 is fixedly installed on one side of the disc 1. A movable plate 27 is installed on the cutting table 24 through a limiting sliding structure. A telescopic component is installed between the cutting table 24 and the movable plate 27. A cutting component that cooperates with the wire and cable 22 is installed on the movable plate 27.

[0039] The limiting sliding structure serves to limit the sliding of the moving plate 27, allowing it to slide smoothly relative to the cutting table 24. The limiting sliding structure includes a strip-shaped sliding hole 25, a limiting sliding rod 26, and a limiting stop. Two strip-shaped sliding holes 25 are symmetrically provided on the cutting table 24. A limiting sliding rod 26 is slidably installed on each of the two strip-shaped sliding holes 25. One end of the limiting sliding rod 26 is fixedly connected to the moving plate 27, and the other end of the limiting sliding rod 26 passes through the strip-shaped sliding hole 25 and is fixedly installed with a limiting stop. The height of the limiting stop is greater than the width of the strip-shaped sliding hole 25. The end face of the strip-shaped sliding hole 25 is square, which can further improve the stability of the limiting sliding rod 26 when it moves.

[0040] The telescopic component includes a fixed block 28, a cylinder 29, and a telescopic rod 30. The fixed block 28 is fixedly installed on the cutting table 24, the cylinder 29 is fixedly installed on the fixed block 28, and the telescopic rod 30 is installed on the cylinder 29. One end of the telescopic rod 30 is fixedly connected to the moving plate 27. The telescopic component can also be replaced by an electric telescopic rod instead of the cylinder 29 and the telescopic rod 30, with the same purpose of driving the moving plate 27 to move smoothly.

[0041] The cutting component includes a fixed connecting rod 31 and a cutting blade 32. Two fixed connecting rods 31 are fixedly installed on one side of the moving plate 27, and a cutting blade 32 is fixedly installed on both fixed connecting rods 31. The cutting blade 32 is designed to cut the wire and cable 22 as required during the movement.

[0042] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0043] In this invention, the pulling of the wire and cable 22 is existing technology. When cutting is required, the servo motor 4 is first turned on. The servo motor 4 drives the rotating gear 13 to rotate through the rotating shaft 5. The rotating gear 13 drives the outer gear ring 9 to rotate. The outer gear ring 9 drives the annular mounting seat 10 to rotate. The annular mounting seat 10 drives the lifting gear 16 to rotate. Initially, the one-way bearing 15 is in a self-locking state. The rotation of the one-way bearing 15 drives the double-direction screw 14 to rotate. The rotation of the double-direction screw 14 allows the lifting block 17 to move back and forth in the vertical direction (moving downward to cut into the insulation of the wire and cable 22, and moving upward to reset). After cutting, the servo motor 4 drives the rotating shaft 5 to rotate in the opposite direction. At this time, the piercing blade 20 will rotate with the annular mounting seat 10, but the piercing blade 20 will not move during the rotation. After one rotation, the insulation of the wire and cable 22 is cut.

[0044] When cylinder 29 is activated, cylinder 29 causes telescopic rod 30 to shorten. Telescopic rod 30 drives cutting blade 32 to move via fixed connecting rod 31. During the movement of cutting blade 32, wire and cable 22 are cut.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
