Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically to a cable cutting device. Background Technology

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power plant lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing. Power cables are cable products used to transmit and distribute high-power electrical energy in the main lines of the power system. During the processing and production of cables, it is often necessary to cut them.

[0003] Chinese patent discloses a signal cable cutting device (authorization announcement number CN211135339U), which achieves the purpose of clamping and fixing the signal cable through the cooperation of the clamp, hydraulic telescopic column and semi-circular groove, thus solving the problem of movement during the cutting of the signal cable. By setting tension rollers on both sides of the cutting box, the signal cable is kept in a taut state during cutting, ensuring the flatness of the cable cut. However, through actual cutting environment, it is known that because the rotating blade is fast during cutting, although the tension roller can play a certain role in tautness of the cable, when the high-speed rotating blade comes into contact with the cable, the spring will move, causing the cable position to shift and resulting in deviation of the cutting position. Utility Model Content

The tilt angles of brackets 53 and 54 are equal, and the tilt angles of brackets 55 and 56 are equal. Guide frame 59 is slidably fitted outside the first mounting frame 2. Second pressure plate 58 is located directly above the first pressure plate 4. The pressing mechanism 5 can drive the two sets of second pressure plates 58 to press down simultaneously, which facilitates simultaneous clamping of both sides of the cable, increases the stability during cable cutting, and prevents the cable from loosening and causing deviation in the cutting position.

[0021] A cutting mechanism 6 is installed at the top center of the processing table 1. The cutting mechanism 6 includes a fastening frame 61, guide rods 62, and an adjusting plate 63. Two guide rods 62 slide through the inside of the fastening frame 61. The adjusting plate 63 is fixed to the bottom end of the two guide rods 62, and springs 64 are sleeved on the outside of the two guide rods 62. A pressure rod 65 is fixed to the top of the two guide rods 62. A motor 66 is fixed to the bottom of the adjusting plate 63. A cutting wheel 67 is fixed to the drive end of the motor 66. The fastening frame 61 is fixed to the top of the processing table 1. One end of the spring 64 is fixed to the pressure rod 65, and the other end of the spring 64 is fixed to the top of the fastening frame 61. The cutting wheel 67 is located above the cutting groove 11. The cutting mechanism 6 can drive the cutting wheel 67 to move down by pressing to complete the cable cutting. After releasing the pressure rod 65, the cutting wheel 67 can be automatically moved up by the action of the spring 64 to facilitate the next cut.

Then, control the servo motor 51 to work. After the servo motor 51 reverses, it can drive the first bracket 53 and the second bracket 54 to reverse. After the first bracket 53 and the second bracket 54 reverse, they can drive the third bracket 55 and the fourth bracket 56 to move, which in turn can drive the two crossbars 57 to move down. After the two crossbars 57 move down, they can drive the two second pressure plates 58 to move down, thereby clamping the two sides of the cable. The motor 66 is powered on, which drives the cutting wheel 67 to rotate. At this time, the user holds the pressure rod 65 and moves it down, which in turn moves the guide rod 62, the adjusting plate 63, the motor 66, and the cutting wheel 67 down. At this time, the spring 64 is in a compressed state. When the cutting wheel 67 moves into the cutting groove 11, it can cut the cable. Then, the pressure rod 65 is released, and the spring 64 gradually returns to its original position, which in turn moves the pressure rod 65, the guide rod 62, the adjusting plate 63, the motor 66, and the cutting wheel 67 up, thus completing the cutting work.
