[0002] In modern society, power cable is widely used in various fields as an important electrical equipment for transmitting and distributing electric energy. The cable is usually made of one or more insulated conductors and an outer insulating protective layer, which can reliably transmit power from a power station to an end user, ensuring stable power supply for industrial production, residential life and various public facilities.

[0003] In actual use of power cable, due to different application scenarios and engineering requirements, the cable often needs to be cut to the appropriate length. The current common cable cutting device mostly adopts mechanical cutting method.

When the two groups of cutting blades extrude and cut the cable, the cable cutting area is subjected to strong extrusion force, resulting in large deformation of the cable cutting end. The deformed cable end is difficult to install in the subsequent use process. SUMMARY

[0034] In the above embodiment, please refer to the specific Figure 1 And Figure 2 The inner wall of the cable cutting machine 1 is provided with four sets of limiting rods 301, which are installed at the corners of the driving plate 3. During the movement of the driving plate 3, the four corners of the driving plate 3 are sleeved on the four sets of limiting rods 301. The limiting rods 301 control the position of the driving plate 3, so that the driving plate 3 always moves horizontally during the movement.

[0035] In the above embodiment, please refer to the specific Figure 3 The top of the fixed block 4 is provided with a connecting block 7, and the end of the connecting block 7 is connected with the limiting rod 301. One end of the fixed block 4 is connected with the bottom of the driving plate 3. In order to ensure that the fixed block 4 uniformly extrudes the plurality of springs 404 connected to the bottom, the other end of the fixed block 4 is fixedly connected with the connecting block 7. The connecting block 7 and the fixed block 4 move synchronously, so that the fixed block 4 can be uniformly stressed.

[0036] In the above embodiment, please refer to the specific Figure 4 The bottom of the fixed sleeve 6 and the top of the fixed plate 601 are provided with clamping grooves 602, and the diameter of the clamping grooves 602 is equal to the diameter of the cable cross section. The fixed sleeve 6 extrudes and fixes the cable by contacting with the fixed plate 601. When the main cutter 5 cooperates with the auxiliary cutter 501 to cut the cable, the cable will deform to a certain extent. The fixed sleeve 6 and the fixed plate 601 on both sides of the cable cutting end face constrain the cable cutting surface, thereby reducing the deformation of the cable caused by cutting.

[0037] In the above embodiment, please refer to the specific Figure 4 A plurality of protrusions 603 are installed in the clamping grooves 602. The protrusions 603 have a certain elastic deformation ability. When the fixed sleeve 6 and the fixed plate 601 extrude the outer wall of the cable by contacting, the fixed sleeve 6 and the fixed plate 601 increase the extrusion and fixing ability of the cable through the protrusions 603 on the inner wall thereof, so as to prevent the cable from sliding during cutting.

[0038] In the above embodiment, please refer to the specific Figure 3 The inside of the fixed sleeve 6 is provided with a limiting groove 401, and the inside of the limiting groove 401 is provided with a limiting block 402. One end of the limiting block 402 is connected with a limiting column 403, and the end of the limiting column 403 is connected with the fixed sleeve 6. The fixed block 4 controls the displacement of the fixed sleeve 6 through the limiting block 402 and the limiting column 403, so as to prevent the fixed sleeve 6 from being deviated in position when extruding the cable.

[0039] In the above embodiment, please refer to the specific Figure 2The bottom surface of the fixing sleeve 6 is lower than the bottom end of the main cutter 5, and the fixing sleeve 6 is first contacted with the outer wall of the cable.

[0040] In the above embodiment, please refer to the specific Figure 3 The top of the auxiliary cutter 501 is at the same height as the bottom end of the clamping groove 602 on the top of the fixing plate 601, and the auxiliary cutter 501 provides a certain amount of supporting force for the cable.

[0041] In the specific work, first, the cable to be cut is placed in the clamping groove 602 on the top of the fixing plate 601, and the cable cutting end surface is adjusted to be on the same vertical plane as the main cutter 5. The hydraulic cylinder 2 pushes down the driving plate 3 to move through the hydraulic rod 201. In the moving process of the driving plate 3, the four corners of the driving plate 3 are sleeved on the four groups of limiting rods 301, and the limiting rods 301 limit and control the driving plate 3, so that the driving plate 3 always keeps horizontal movement in the moving process. Because the bottom surface of the fixing sleeve 6 is lower than the bottom end of the main cutter 5, the fixing sleeve 6 is first contacted with the cable in the driving plate 3 moving process, and the fixing sleeve 6 is extruded and fixed to the cable by the fixing plate 601. Then, the main cutter 5 moves downward and cooperates with the auxiliary cutter 501 to cut the cable. When the main cutter 5 contacts the cable and cuts the cable downward, the fixing block 4 continues to move downward with the main cutter 5, the movement of the fixing block 4 extrudes and shrinks the spring 404, and the spring 404 extrudes the fixing sleeve 6 downward. With the increase of the descending distance of the fixing block 4, the extrusion force of the spring 404 on the fixing sleeve 6 is also increased, so that the fixing sleeve 6 and the fixing plate 601 extrude and fix the cable cutting surface end, preventing the cable from being greatly deformed due to the great extrusion force of the main cutter 5 and the auxiliary cutter 501.
