A power cable cutting and processing device

Abstract

The present invention discloses a power cable shearing and processing device, which relates to the field of cable cutting technology, and includes a base, on which an extrusion limiting mechanism for straightening the cable is arranged, and a cutting knife is arranged above the base. In the present invention, when in use, the position of the extrusion roller is first adjusted by a first motor, a bidirectional screw rod, and an L-shaped block, and then the moving distance of the slider is adjusted by a winding roller and a pull rope. When the adjustment is completed, the movable column is rotated by a second motor, and the rotation of the movable column causes the extrusion roller to rotate. The rotation of the extrusion roller will cause the cable to be horizontally extruded, straightened, and transported under the action of a fixed limiting block and a movable limiting block. At the same time, the rotation of the movable column will cause the pressing plate to reciprocate and descend, thereby vertically extruding and straightening the cable, so that cables of any diameter are straightened and limited before cutting, and the situation that the cutting position is not perpendicular to the cutting knife and guides the oblique cutting is avoided.

Description

Technical Field

[0001] The invention relates to the technical field of cable cutting, and in particular to a power cable shearing processing device. Background Art

Each group of conductors is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. Wires and cables refer to materials used for power, communications and related transmission purposes. There is no strict boundary between "wires" and "cables". Products with a small number of cores, small product diameters, and simple structures are usually called wires. Those without insulation are called bare wires, and the others are called cables. Conductors with larger cross-sectional areas (greater than six square millimeters) are called large wires, and those with smaller cross-sectional areas (less than or equal to six square millimeters) are called small wires.

[0043] Working principle of the present invention:

[0044] (1) When in use, first place the cable on the base 1 and make the cable contact the two squeezing rollers 9, then start the second motor 11, the output of the second motor 11 will cause one of the movable columns 12 to rotate, the rotation of one of the movable columns 12 will cause the rectangular column 13 to rotate, the rotation of the rectangular column 13 will cause the movable cylinder 14 to rotate, the rotation of the movable cylinder 14 will cause the second bevel gear 16 to rotate, the rotation of the second bevel gear 16 will cause the first bevel gear 10 to rotate, the rotation of the first bevel gear 10 will cause the rotating rod 8 to rotate, the rotation of the rotating rod 8 will cause the squeezing roller 9 to rotate, the rotation of the squeezing roller 9 will be under the action of the fixed limit block and the movable limit block 6 The cable will be squeezed and straightened laterally, and the cable will be conveyed toward the cutting knife 33. At the same time, the rotation of the rectangular column 13 will cause the other movable column 12 to rotate, and the rotation of the other movable column 12 will cause the circular plate 22 to rotate. The rotation of the circular plate 22 will cause the eccentric rod 23 to rotate eccentrically. The eccentric rotation of the eccentric rod 23 will pull the pull rope 21 through the sleeve 24. The pull rope 21 is stressed and the slider 18 will drop. The drop of the slider 18 will cause the U-shaped moving block 26 to drop. The drop of the U-shaped moving block 26 will cause the pressing plate 27 to drop. The drop of the pressing plate 27 will squeeze and straighten the cable vertically. When the pull rope 21 is not stressed, the spring 19 The slider 18 will be reset under the action of the slider 18, and the reset of the slider 18 will reset the pressing plate 27, thereby cyclically pressing and straightening. When the cable moves a certain distance, the telescopic hydraulic cylinder 29 is started, and the output of the telescopic hydraulic cylinder 29 will cause the mounting plate 30 to drop. The lowering of the mounting plate 30 will cause the cutting knife 33 to drop through the movable plate 31, thereby cutting the cable, thereby straightening the cable before cutting, avoiding the situation where the cutting point is not perpendicular to the cutting knife and causing oblique cutting. When the cable diameter is large or small, the first motor 2 is started, and the output of the first motor 2 will cause the bidirectional screw rod 3 to rotate. The rotation of the bidirectional screw rod 3 under the action of the guide rod 5 will make The L-shaped blocks 4 move closer to or farther away from each other, which will cause the movable limit block 6 to move, and the movement of the movable limit block 6 will cause the U-shaped movable block 7 to move, and the movement of the U-shaped movable block 7 will cause the squeezing roller 9 to move through the rotating rod 8, thereby causing the squeezing roller 9 to contact cables of different diameters, and then the knob is turned, and the rotation of the knob will cause the winding rod 20 to rotate, and the rotation of the winding rod 20 will reel in or relax the pull rope 21, and the winding or relaxation of the pull rope 21 will change the moving distance of the slider 18, and the change in the moving distance of the slider 18 will change the moving distance of the pressing plate 27, thereby straightening cables of different diameters.

[0045] (2) When the movable column 12 rotates, one of the transmission wheels 39 will rotate, and the rotation of one of the transmission wheels 39 will cause the other transmission wheel 39 to rotate through the belt 40. The rotation of the other transmission wheel 39 will cause the moving rod 37 to rotate. The rotation of the moving rod 37 will cause the fourth bevel gear 38 to rotate. The rotation of the fourth bevel gear 38 will cause the third bevel gear 36 to rotate. The rotation of the third bevel gear 36 will cause the movable rod 34 to rotate. The rotation of the movable rod 34 will cause the cleaning roller 35 to rotate, thereby cleaning the surface of the cable and cleaning the cutting opening at the same time to prevent the cutting hole from being contaminated by debris.
