Description

Technical Field

[0001] The utility model belongs to the technical field related to cable production, and particularly relates to a device for removing burrs from the surface of a cable. Background Art

[0002] In the single-wire drawing process of cable conductors, when the metal rod passes through a series of die holes with gradually decreasing apertures, burrs may be generated on the surface of the single wire due to die wear, poor lubrication and other reasons. The cable burrs will cause electric field distortion, and a large amount of unbalanced charges will gather around the burrs, constantly impacting the insulating medium, which may cause insulation breakdown. Even if there are no problems in the withstand voltage and partial discharge tests, as time goes by and the charges continue to impact, the discharge branches at the defects will continue to grow and spread to the outer layer of the insulation, eventually causing electrothermal breakdown. The burrs may affect the mechanical properties of the cable, such as flexibility and tensile strength. During the laying and use of the cable, it is easy to cause problems such as cable surface wear and cracking, reducing the service life of the cable. For high-voltage cables, burrs may cause tip discharge, causing safety accidents such as leakage and short circuit, causing harm to personnel and equipment. Therefore, it is necessary to remove the burrs on the surface of the cable conductor through a burr removal device or structure, but it still has the following disadvantages in actual use:

[0003] 1. When the burr removal device on the cable surface is working, the burrs on the cable surface are removed by grinding and other operations. When dealing with burrs on the surface of cable conductors with different diameters, it is necessary to cooperate with the replacement of processing structures with different diameters, which makes the burr removal inconvenient;

[0004] 2. Secondly, in the process of removing burrs from the surface of the cable conductor, a large amount of debris, dust generated by grinding, etc. will be generated, which will remain in the grinding equipment or be scattered in the working environment, requiring additional cleaning and treatment, which is not convenient to use.

Specific embodiment 1

[0026] See also Figure 1-5 The utility model is a burr removal device for a cable surface, comprising a conveying chamber 1, a driving assembly 2 and a grinding disc 3. Two driving assemblies 2 are arranged in parallel in the vertical direction on the rear side of the conveying chamber 1. When the conveying chamber 1 is working, the cable conductor 4 to be ground passes through it, and the driving assembly 2 generates power to drive the grinding disc 3 to rotate. The driving assembly 2 comprises a rotating block 201, a rotating disc 204 and a reducer 205. The reducer 205 is fixed to the rear side of the conveying chamber 1 and the output shaft passes through the rear side of the conveying chamber 1.

The rotating block 201 is fixed on the end of the rotating disc 204 away from the reducer 205. The rotating disc 204 and the rotating block 201 are both arranged in the conveying chamber 1. When the reducer 205 is working, the output power is transmitted to the rotating disc 204 on the output shaft, driving the rotating disc 20 4 rotates, and the rotating block 201 is fixed with the rotating disk 204 to drive the rotating block 201 to rotate. The outer sides of the two rotating blocks 201 are movably connected with grinding disks 3, and the grinding disks 3 are movably connected with the rotating block 201, so that when the rotating block 201 and the rotating disk 204 rotate, they rotate with the rotation of the rotating disk 204. An annular grinding groove 304 is opened on the circumference of the grinding disk 3, and the cable conductor 4 to be polished is movably arranged through the grinding groove 304, so that the burrs on the cable conductor 4 are ground off and fall into the space in the conveying chamber 1.
