Detailed Description
The invention will be further illustrated with reference to the accompanying figure 1 and examples:
as shown in fig. 1: the middle and low voltage cable insulation cutting pliers comprise a right pliers body 9 and a left pliers body 10, wherein the middle parts of the right pliers body 9 and the left pliers body 10 are hinged in a crossed mode through pliers body hinges 12. The front end of the right forceps body 9 is provided with a longitudinal fixing groove 13, the longitudinal fixing groove 13 is perpendicular to the right forceps body 9, and the position corresponding to the left forceps body 10 is provided with a longitudinal blade 2 which forms a cutting combination with the longitudinal fixing groove 13. The rear end of the left forceps body 10 is provided with a transverse fixing groove 11, the transverse fixing groove 11 is perpendicular to the left forceps body 10, and a transverse blade 6 is arranged at the corresponding position of the right forceps body 9 and forms a cutting combination with the transverse fixing groove 11.
The transverse blade 6 is arranged on the right clamp body 9 through a transverse blade pressing block 7, and two ends of the transverse blade pressing block 7 are provided with pressing bolts for fastening.
The longitudinal blade 2 is superposed with the central line of the longitudinal fixing groove 13, and the transverse blade 6 is perpendicular to the central line of the transverse fixing groove 11.
The longitudinal blade 2 is fixed at the front end of the left clamp body 10 through the longitudinal blade compression bolt 1, and the front end of the left clamp body 10 is provided with a limiting adjusting bolt 3 so as to adjust the cutting depth.
The working principle of the low-voltage cable insulation cutting clamp is as follows:
the exposed length of the longitudinal blade 2 relative to the lower end of the left clamp body 10 is 2mm-4mm more than the depth of a required cable cutting layer, the exposed length of the transverse blade 6 relative to the lower end of the right clamp body 9 is 2mm-4mm more than the depth of the required cable cutting layer, and the exposed lengths are all 3mm in the embodiment.
Firstly, a longitudinal blade 2 is arranged in a left clamp body 10 and the longitudinal blade 2 is pressed tightly by adjusting a longitudinal pressing bolt 1, and the exposed length of the arranged longitudinal blade 2 relative to the lower end of the left clamp body 10 is more than 3mm than the depth of a cable layer to be cut. The front end of the cable is used as a trial cutting part, the cable is placed in the longitudinal fixing groove 13, the left clamp body 10 and the right clamp body 9 are held by hands to clamp the cable 14 in the longitudinal fixing groove 13 tightly, the longitudinal blade 2 is adjusted to the required cutting depth by adjusting the limiting adjusting bolt 3 for trial cutting, and whether the cutting depth meets the specified depth is observed after trial cutting. If the requirement is not met, the limit adjusting bolt 3 is adjusted in time, and the locking nut 4 is locked to prevent the size change after the required depth is reached.
The transverse blade 6 is aligned to the position of the size to be cut, the left clamp body 10 and the right clamp body 9 are tightly held by hands to clamp the cable 15 in the transverse fixing groove 11, the limiting adjusting bolt 3 on the left clamp body 10 cannot further penetrate after reaching the limiting position of the right clamp body 9, the transverse blade 6 is installed according to the depth of the semiconductor electric shielding layer, and the exposed length of the transverse blade 6 relative to the lower end of the right clamp body 9 is 3mm more than the depth of the semiconductor electric shielding layer. Then the cable or the cutting pliers are rotated at a constant speed to cut. Because the cable is positioned in the transverse fixing groove 11, the circumferential track operation can be accurately realized under the condition that the left clamp body 10 and the right clamp body 9 are clamped, and the uniform and stable cutting depth is achieved.
When the insulating layer is cut, the insulating layer is cut for many times according to the operation mode because the thickness of the insulating layer is larger in the annular cutting process. When the longitudinal cutting is carried out, after the circumferential cutting is finished, the longitudinal blade 2 is aligned to the insulating layer of the part needing to be removed, the left clamp body 10 and the right clamp body 9 are pressed down forcibly, after the preset depth is reached, the cutting clamp is rotated 180 degrees to the opposite side of the original cutting position, the operation is carried out according to the method, and after the operation is finished, the cable insulating layer can be easily pried by using a screwdriver.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
