[0023] Refer to the attached Figure 1-3 A steel core aluminum stranded wire ring cutting and stripping device comprises a shell 1, which is in a circular ring shape as a whole. A handle 3 and a fixing block 4 are fixedly installed on one side of the shell 1, and the handle 3 and the fixing block 4 are parallel to each other. An annular groove 2 is provided in the inner ring of the shell 1, and a ring cutting mechanism 5 is installed in the annular groove 2. The ring cutting mechanism 5 comprises an outer gear ring 51, a pinion 53, a reduction motor 52, a bow frame 57 and a high-temperature electric heating alloy wire 58. The high-temperature electric heating alloy wire 58 is circularly installed in the inner ring of the annular groove 2, and the two ends of the high-temperature electric heating alloy wire 58 are straightened and bound to the two ends of the bow frame 57. The outer gear ring 51 is rotatably installed in the annular groove 2, and the pinion 53 is meshingly installed on the outer side of the outer gear ring 51. The pinion 53 and the output shaft of the reduction motor 52 are fixedly connected through a coupling, and the reduction motor 52 and the shell 1 are fixedly connected.

[0024] In this embodiment, a fixed plate 55 is telescopically installed on one side of the bow frame 57 through two guide rods 59. The fixed plate 55 and the guide rod 59 are fixedly connected. The end of the guide rod 59 slides through the bow frame 57. A thrust spring 56 is squeezed and arranged between the fixed plate 55 and the bow frame 57. The two ends of the thrust spring 56 are respectively fixedly connected to the fixed plate 55 and the bow frame 57. An electric push rod 54 is connected between the inner wall of the outer gear ring 51 and the fixed plate 55. The electric push rod 54 is fixedly connected to the inner wall of the outer gear ring 51. The end of the push rod in the electric push rod 54 is fixedly connected to the fixed plate 55. The electric push rod 54 is arranged in the radial direction of the outer gear ring 51.

[0025] In this embodiment, two coaxial clamping mechanisms 6 are symmetrically installed at the upper and lower ends of the shell 1. The coaxial clamping mechanism 6 includes an annular cover plate 61, a plurality of clamping blocks 64, a plurality of driving columns 68 and a connecting plate 67. The annular cover plate 61 is in a circular shape as a whole. The inner ring of the annular cover plate 61 is larger than the outer diameter of a general steel core aluminum wire and can be used to cut the outer skin of steel core aluminum wires of various sizes. The annular cover plate 61 is fixedly connected to the shell 1. A plurality of guide grooves 62 and a plurality of circular holes 63 are evenly arranged on the annular cover plate 61. The plurality of guide grooves 62 and the plurality of circular holes 63 are all arranged in a circular shape. A plurality of clamping blocks 64 are rotatably installed in the plurality of circular holes 63 through rotating shafts 65 respectively. A plurality of clamping blocks 64 are provided with strip holes 66. A plurality of driving columns 68 respectively pass downward through the plurality of strip holes 66 and the plurality of guide grooves 62. The connecting plate 67 is fixedly installed on the top of the plurality of driving columns 68.

[0026] In this embodiment, a handle 2 7 is fixedly connected between the connecting plates 67 in the two coaxial clamping mechanisms 6. The handle 2 7 is arranged between the handle 1 3 and the fixed block 4. A tension spring 8 is arranged between the handle 2 7 and the fixed block 4. The present application mainly utilizes the elastic force of the tension spring 8 to automatically pull the handle 2 7 close to the fixed block 4. When the handle 2 7 is close to the fixed block 4, the handle 2 7 will drive the two connecting plates 67 and a plurality of driving columns 68 to rotate clockwise along the plurality of guide grooves 62, and then the plurality of driving columns 68 will drive the ends of the plurality of clamping blocks 64 to rotate counterclockwise, so that the ends of the clamping blocks 64 gradually move away from the center of the annular cover plate 61.

[0027] It should be added that the reduction motor 52, the electric push rod 54 and the high-temperature electric heating alloy wire 58 in the present application are respectively connected to the external power supply through wires, and the wires connecting the reduction motor 52 and the high-temperature electric heating alloy wire 58 are connected in series with a handle switch for the electric vehicle. The handle switch is fixedly mounted on the handle 2 7. By holding the handle 2 7 close to the handle 1 3, the handle switch is turned on to connect the circuit between the reduction motor 52 and the high-temperature electric heating alloy wire 58.

[0028] The process of stripping the outer skin of steel core aluminum wire using the utility model is as follows:

[0029] 1) Pass the stripped steel core aluminum wire through the inner ring of the annular cover plate 61 in the two coaxial clamping mechanisms 6. The two coaxial clamping mechanisms 6 can clamp steel core aluminum wires of different diameters;

[0030] 2) Manually hold the second grip 7 and the first grip 3 tightly, and rotate the second grip 7 counterclockwise to approach the first grip 3. The second grip 7 will drive the two connecting plates 67 and the plurality of driving posts 68 to rotate counterclockwise along the plurality of guide grooves 62, and then the moving plurality of driving posts 68 will drive the ends of the plurality of clamping blocks 64 to rotate clockwise, so that the ends of the clamping blocks 64 gradually approach the center of the annular cover plate 61, and at the same time, the plurality of clamping blocks 64 in the two coaxial clamping mechanisms 6 are synchronously clamped and installed on the periphery of the steel core aluminum wire, so that one end of the steel core aluminum wire is coaxially clamped and installed in the inner circle of the annular groove 2;

[0031] When the above-mentioned grip 2 7 is close to the grip 1 3, the circuit of the reduction motor 52 and the high-temperature electric heating alloy wire 58 can be synchronously connected through the handle switch. After the reduction motor 52 is energized, the output shaft of the reduction motor 52 is used to drive the small gear 53 to rotate slowly, and the meshing outer gear ring 51 drives the bow frame 57 and the high-temperature electric heating alloy wire 58 to rotate in the inner ring of the annular groove 2. After the high-temperature electric heating alloy wire 58 is energized, it is used to generate high temperature. The high temperature generated by the high-temperature electric heating alloy wire 58 in this application is lower than the melting point of the aluminum wire in the steel core aluminum wire, and higher than the temperature of melting the outer skin of the steel core aluminum wire. This application mainly utilizes the high-temperature electric heating alloy wire 58 for high-temperature melting and mechanical cutting. The shearing force of the high-temperature electric heating alloy wire 58 is lower than the shearing force of the traditional sawtooth, and will not cause damage to the aluminum wire inside the steel core aluminum wire. In addition, this application does not need to accurately set the cutting depth of the high-temperature electric heating alloy wire 58, and can quickly complete the peeling of the outer skin of the steel core aluminum wire, which not only saves manpower and time, but also ensures that the cutting surface is clean.

[0032] 3) The push rod in the electric push rod 54 is extended outward to push the fixing plate 55, the thrust spring 56, the bow frame 57 and the high-temperature electric heating alloy wire 58 in sequence to be close to and squeezed on the outer skin of the steel-core aluminum wire. When the high-temperature electric heating alloy wire 58 and the outer skin of the steel-core aluminum wire are squeezed and contacted with each other, the thrust spring 56 can also be compressed to accumulate the energy of the thrust spring 56, which can be used to push the high-temperature electric heating alloy wire 58 to cut the outer skin of the steel-core aluminum wire, and there is no need to adjust the extension length of the electric push rod 54 multiple times.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
