Description

Technical Field

[0001] The utility model relates to the technical field of cable production equipment, in particular to a cutting device for producing electric wires and cables. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are referred to as cables, and cables in a narrow sense refer to insulated cables. In the prior art, when cutting cables, there is a lack of good limiting and fixing effects. If the fixation is not firm enough, it is easy to move during the cutting process, resulting in poor cutting products. During the cutting process, there is no auxiliary pressure holding effect on the cable.

[0003] For example, the authorized patent document with application number CN202320756450.8 discloses a cutting device for cable and wire production, which includes a support and installation stable base located at the bottom, the left and right sides of the support and installation stable base are connected to the main support connecting frame by welding, the upper ends of the left and right main support connecting frames are connected together by a support connecting crossbeam, the lower end of the support and installation stable base is provided with an integral installation matching groove opening downward, the front of the main support connecting frame is provided with a cylindrical integral installation fastening hole communicating with the integral installation matching groove at the lower end, and the front upper end of the main support connecting frame is provided with a spare fastening connection hole. Through the above technical scheme, it is ensured that the cutting position can prevent overall deformation under the action of the matching groove, which solves the technical problems in the related art that the cable and wire cutting equipment occupies a large space, and the cutting port position will produce serious deformation and need later correction.

[0004] The above patent has the problem that when cutting the cable, it lacks a good limiting and fixing effect. If the fixation is not strong enough, it is easy to move during the cutting process, resulting in poor cutting products. During the cutting process, it does not have an auxiliary pressing effect on the cable. Therefore, we need to provide a cutting device for the production of wires and cables. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a cutting device for manufacturing wires and cables, comprising:

[0027] An operating table 1, and a top plate 2 fixedly mounted on the surface of the operating table 1;

[0029] A base 6 fixedly mounted on the top of the operating table 1, and a holding mechanism 7 disposed on the top of the base 6 for limiting the position of the cable;

[0030] A feeding mechanism 8 for cable transportation is arranged on both sides of the top of the workbench;

[0031] The holding mechanism 7 includes two grooves 71 opened inside the base 6, and double-threaded rods 72 are rotatably installed inside the two grooves 71. Slide blocks 73 are threadedly installed on both sides of the surface of the double-threaded rods 72. Push rods 74 are hinged on the tops of the two slide blocks 73, and a pressure rod 75 is hinged on the adjacent side of the two push rods 74, and a first motor 76 is installed at one end of the double-bolt rod.

[0032] The surface of the slider 73 is slidably mounted inside the groove body 71, and the top of the base 6 is provided with a strip groove 9 adapted to the cutting tool 5;

[0033] In this embodiment, the cable is passed through two feeding mechanisms 8 and placed on the top of the base 6. The first motor 76 is started to drive the double-threaded rod 72 to rotate, and the two sliders 73 on the surface of the double-threaded rod 72 are close to or away from each other, thereby controlling the swing of the two push rods 74, and finally achieving the pressing of the cable by the pressing rod 75. Among them, the two cylinders 3 are synchronous cylinders 3. The starting cylinder 3 drives the lower pressure plate 4 to move downward, and the cutting tool 5 falls quickly to cut the fixed cable to avoid the cable not having a good fixing effect, which makes the cable easy to shake. A strip groove 9 is provided for the insertion of the cutting tool 5 to avoid the bottom of the cutting tool 5 directly contacting the base 6 and shortening the service life.

[0034] An auxiliary pressing plate 10 is installed at the bottom of the lower pressing plate 4 through two supporting springs 13, and a strip-shaped portion is integrally processed at the bottom of the auxiliary pressing plate 10;

[0035] Specifically, when the lower pressing plate 4 moves downward, the bottom line of the auxiliary pressing plate 10 first contacts the cable, and the strip at the bottom of the auxiliary pressing plate 10 enhances the friction force, and the support spring 13 is compressed to press the cable on the cutting tool 5.

[0036] Two support rods 11 are fixedly mounted on the top of the auxiliary pressing plate 10. The upper ends of the two support rods 11 penetrate the top of the lower pressing plate 4 and extend. The surfaces of the support rods 11 are movably sleeved with the inner part of the support spring 13.

[0037] Furthermore, the support rod 11 is arranged inside the support spring 13 to prevent the support spring 13 from bending and becoming unusable, while enhancing the stability of the movement of the auxiliary pressure plate 10 .

[0040] In order to adapt to cables of different diameters and to limit the cable at the center of the roller 84 to prevent it from deviating, an annular groove 12 is formed on the surface of the roller 84 and the driving wheel 86 .

[0041] In order to prevent the support rods 11 from being separated from the lower pressing plate 4 , the surfaces of the two support rods 11 are integrally processed with limiting ring portions.

[0042] In this device, the cable passes through two feeding mechanisms 8 and is placed on the top of the base 6. The first motor 76 is started to drive the double-threaded rod 72 to rotate, and the two sliders 73 on the surface of the double-threaded rod 72 are close to or away from each other, thereby controlling the swing of the two push rods 74, and finally achieving the pressing of the cable by the pressing rod 75. Among them, the two cylinders 3 are synchronous cylinders 3. The starting cylinder 3 drives the lower pressure plate 4 to move downward, and the cutting tool 5 falls quickly to cut the fixed cable to avoid the cable not having a good fixing effect, which makes the cable easy to shake. A strip groove 9 is provided for the insertion of the cutting tool 5 to avoid the bottom of the cutting tool 5 directly contacting the base 6 and shortening the service life.
