Description

Technical Field

[0001] The utility model relates to the technical field of superconducting wire production, in particular to a superconducting wire pay-off device. Background Art

[0002] Superconducting wires are made of superconducting materials and are capable of carrying high-density currents under strong magnetic fields.

[0003] In the process of wire processing of superconducting wires, it is generally necessary to draw ingots or rods made of superconducting materials through multiple drawing processes to draw them into wires. In the drawing process, usually one drawing machine draws multiple groups of superconducting wires at the same time. The superconducting wires need to be laid out in front of the drawing machine and bundled through the pay-off frame and pulled into the drawing machine. The existing wire pulleys often jump out of the groove due to the twisting of the superconducting wires during the drawing process; in addition, the bundled wire frame uses multiple wire pulleys arranged side by side, and the superconducting wires often jump out of the wire pulleys due to the jump of the wires, which in turn causes the wires to break, or the wires to get entangled, or the wires get stuck, causing production to stop.

[0027] In the utility model, the cleaning wire mechanism 8 also includes a mounting seat symmetrically arranged on the top of the fixed frame 1, and the two ends of the mounting seat away from the fixed frame 1 are symmetrically rotated and connected to multiple first wire wheels 81, and the two ends of the mounting seat away from the fixed frame 1 are symmetrically arranged with two first cleaning rollers 82, and the first cleaning rollers 82 are arranged at the outlet end of the first wire wheel 81.

[0028] In the present invention, the transition conductor mechanism 9 includes an L-shaped mounting frame with one end connected to the fixed frame 1 away from the conductor roller 7, and a plurality of second conductor wheels 91 are arranged at the other end of the mounting frame, and a first wire pressing roller 92 is also arranged at the outlet end of the second conductor wheel 91.

[0029] In the utility model, the tensioning mechanism includes a connecting frame connected to the side of the fixed frame 1 away from the wire roller 7, a guide roller 12 is vertically arranged at the center of the connecting frame, a slider 13 is slidably connected to the surface of the guide roller 12, one end of the slider 13 is connected to the driving end of the telescopic gas rod 10 through a connecting block 11, and the other end of the slider 13 is connected to a tensioning frame 14.

[0031] In the present invention, multiple groups of directional blocks 1701 are provided, and the multiple groups of directional blocks 1701 are symmetrically distributed with the top center of the tensioning mechanism as the midpoint, and the inclination angle of each group of directional blocks 1701 is inclined toward the top center of the tensioning mechanism.

[0034] Embodiment: When in use, first move the entire device to the wire inlet end of the wire drawing machine through the moving wheel 18 to ensure that the wire outlet direction of the directional wheel 1703 is facing the wire inlet end of the wire drawing machine. Then install the wire skeleton 5 with superconducting wires on the rotating shaft 4 on both sides of the fixed frame 1 respectively, and fix the wire skeleton 5 by tightening nuts at both ends of the rotating shaft 4 away from the center. Prevent the wire skeleton 5 from falling off during the rotation process. Then the superconducting wire passes through the wire roller 7, the cleaning wire mechanism 8, the transition wire mechanism 9, the tensioning mechanism, the wire outlet wire mechanism 16 and the wire directional mechanism 17 in sequence, and finally enters the wire drawing machine for drawing. The wire roller 7 is connected to the positioning plate 2 on the fixed frame 1 through the column 6, and the multiple columns 6 are not in the same straight line in the vertical direction, but the columns 6 on the same side are away from the wire skeleton 5 from top to bottom, and the bottom column 6 is farthest from the wire skeleton 5 on the same layer, ensuring that the superconducting wire does not get entangled when it is pulled out through the wire skeleton 5.

The outlet end of the first wire wheel 81 is provided with a first cleaning roller 82. Two first cleaning rollers 82 are symmetrically arranged up and down, and the superconducting wire passes between the two first cleaning rollers 82, and the superconducting wire is first cleaned by the first cleaning roller 82. The cleaned superconducting wire passes through the second wire wheel 91 and the first wire pressing roller 92, then passes through the bottom surface of the tension wheel 15, then passes between the third wire wheel 1603 and the second wire pressing roller 1602, and finally passes through the directional wheel 1703 and the second cleaning roller 1702, and enters the inlet end of the wire drawing machine. There are multiple groups of directional blocks 1701, which are symmetrically distributed with the top center of the tensioning mechanism as the midpoint, and the inclination angle of each group of directional blocks 1701 is inclined toward the top center of the tensioning mechanism to ensure that the superconducting wires entering the wire drawing machine are all facing the center direction of the wire drawing machine's inlet end.

[0035] During the processing, the telescopic gas rod 10 drives the slider 13 to move up and down along the surface of the guide roller 12, thereby adjusting the tensioning force on the superconducting wire to ensure that the superconducting wire entering the wire drawing machine is always in a tensioned state.

The first cleaning roller 82 and the second cleaning roller 1702 can effectively clean the superconducting wire to prevent the presence of debris on the surface of the superconducting wire entering the wire drawing machine. At the same time, the first cleaning roller 82, the first crimping roller 92, the second crimping roller 1602 and the second cleaning roller 1702 can ensure that the superconducting wire will not jump out of the grooves on the surfaces of the first wire wheel 81, the second wire wheel 91, the third wire wheel 1603 and the directional wheel 1703 during the drawing process, and play a role in pressing and limiting the superconducting wire.
