Description

Technical Field

[0001] The invention relates to the technical field of cable stripping devices, in particular to a cable stripping device and a working method. Background Art

[0002] When installing cables, it is often necessary to peel off the outer sheath of the cable ends, and then twist the exposed ends of the two cable ends together to form a passage for the two cables, or use a connector to connect the exposed metal cable cores of the two cable ends. In the actual operation process, the staff mainly relies on using wire strippers to strip the outer sheath of the cable ends. Although this method makes the operation more convenient and is suitable for a small amount of wiring operations, it requires greater physical strength of the workers for large-scale projects or automated production wiring operations. Especially when stripping wires in large quantities, this method will lead to reduced operating efficiency of the workers.

[0003] With the development of automation, there are also corresponding wire stripping devices. For example, the patent publication number is: CN 112688241 A discloses a stripping device and method for a high-voltage cable head, which belongs to the field of power supply maintenance technology. Technical solution: Use a wallpaper knife to manually remove a section of the shielding layer, steel armor layer and rubber layer of the high-voltage cable head to expose the semiconductor layer; use a cable head cutter to remove a small section of the conductor, insulation layer and semiconductor layer on the end of the high-voltage cable head; use a cable insulation stripper to install a vertical knife to insert the remaining section of the semiconductor layer to separate the insulation layer and the semiconductor layer; use a cable insulation divider to divide the semiconductor layer into three parts, use pliers to tear the three parts of the semiconductor layer to the root, and remove them with a wallpaper knife; then use a cable insulation joint stripper to disassemble the vertical knife and install a bevel knife, insert the remaining section of the insulation layer into the cable insulation joint stripper, remove the insulation layer, and expose a section of the conductor. The present invention can complete the cable insulation cutting work in a short time, greatly improving the safety of the operator; it has extremely strong reliability and durability, and is suitable for various work occasions.

[0004] Another example is the patent publication number: CN 117477452 A, a portable cable stripping electric tool, in which a clamping part, a linear cutting part and an annular cutting part are fixedly installed in the shell; the cable head is clamped by the clamping part, and the linear cutting part moves linearly from left to right, so that the sealing sheath of the cable cuts a cutting groove from left to right, and the annular cutting part rotates to cut an annular groove of the sealing sheath of the cable, and the right end of the cutting groove intersects with the annular groove, so that the sealing sheath can be unfolded and removed from the cable. The present invention realizes the one-time cutting and removal of the sealing sheath of the cable, and the linear cutting part is used to cut along the axial direction of the cable, and the annular cutting part is used to cut along the normal direction of the cable. Before cutting, the cutting depth of the first blade is adjusted by the first telescopic part, and the cutting depth of the second blade is adjusted by the second telescopic part, so as to avoid the cable core being damaged by the cutting blade, and the cable is fixed and moved by the clamping part to adjust the cutting position, which is suitable for use in most scenes of electrical work.

[0005] Although the above patent can meet the requirement of cutting the insulating cloth of the cable head through a mechanical structure, in actual operation, although it solves the operation of cutting and stripping the wire, the cable head needs manual support during the cutting process. Although it can ensure the safety of personnel, manual participation in the operation process can easily lead to inaccurate stripping position. Moreover, after the cable head is cut, manual assistance is required for the isolated insulation layer and cable core. The operation is cumbersome and does not truly realize the automated cable stripping operation.

The clamping blocks 4 can slide freely up and down in the slot. In addition, clamping cylinders 5 are vertically installed at the upper and lower ends of the clamping seat 3.

[0056] When stripping the cable, first pass the end of the cable through the clamping openings of the two clamping blocks 4, and then pass the end of the cable between the two arc-shaped cutters 24, start the two clamping cylinders 5, the cylinder rods of the clamping cylinders 5 extend, and drive the two clamping blocks 4 to approach each other, so that the inner walls of the clamping openings of the two clamping blocks 4 clamp the cable sheath together. When the rotating part 12 starts to rotate, the ball 18 is subjected to the elastic resistance force of the spring 7 on the mounting arm 8, and rolls from the end face of the rotating part 12 to the surface of the protrusion 16, so that the mounting arm 8 moves away from the vertical plate 11, so that the clamping seat 3 moves away from the vertical plate 11. Therefore, the cable clamping unit moves away from the vertical plate, so that the cut sheath can be separated from the cable. Compared with the wire stripping method in the prior art, the labor intensity of the workers is greatly reduced. In addition, the operation is simple and has a certain degree of automation.

At the same time, as the rotating part 12 rotates, the arc cutter 24 will perform annular cutting on the outer skin of the cable. When the rotating part 12 rotates 180 degrees, the outer skin of the cable is completely cut off in an annular shape. At this time, when the rotating part 12 rotates to the right position, the ball 18 is subjected to the elastic resistance force of the spring 7 on the mounting arm 8, and the ball 18 rolls from the end face of the rotating part 12 to the surface of the protrusion 16, so that the mounting arm 8 will move in the direction away from the vertical plate 11, so that the clamping seat 3 moves in the direction away from the vertical plate 11, so that the clamping block 4 pulls the cable, so that the cut outer skin of the cable is separated from the cable, thereby completing the cable stripping operation.
