Annealing device capable of preventing sparking and eliminating resistance for power cable

Abstract

The invention discloses an annealing device capable of preventing sparking and eliminating resistance for a power cable. The annealing device structurally comprises a reinforcing base, pay-off discs,a top seat and a contact electric brush annealing machine. The pay-off discs are arranged at the upper end of the reinforcing base, the top seat is fixedly mounted at the top end of the reinforcing base, the pay-off discs are located at the left end of the contact electric brush annealing machine, the bottom end of the contact electric brush annealing machine is fixedly mounted on the reinforcingbase, and the top end of the contact electric brush annealing machine is fixedly connected with the top seat. The cable is extruded through extrusion cable contact mechanisms, it is guaranteed that contact between the cable and an electrode wheel is better, the sparking phenomenon is reduced, meanwhile, sparking can be eliminated through sparking eliminating electrodes, and the surface quality ofthe cable is improved. In the rotating process of the electrode wheel, when the resistance is increased, heat generated by the electrode wheel is increased, at the moment, a hot air thrust mechanism absorbs hot air and applies certain thrust to the electrode wheel, the electrode wheel normally rotates, it is guaranteed that the resistance is unchanged, the cable is prevented from being stretched,and it is guaranteed that the forming wire diameter of the cable is consistent front and back.

Description

technical field [0001] The invention relates to the field of cable processing equipment, in particular to an annealing device for preventing ignition and eliminating resistance. Background technique [0002] After the power cable conductor is cold-drawn, there is a hardening phenomenon. To eliminate the cold-drawing hardening phenomenon and increase the elongation, it must be annealed to eliminate internal stress and defects. Among them, the contact brush transmission high-current annealing machine can Realizing high-speed continuous annealing and relatively energy-saving, as one of the commonly used annealing treatment devices, but the current contact brush transmission high-current annealing machine has the following disadvantages: [0003] During the cable annealing process of the contact brush transmission high-current annealing machine, the electrode wheel inside the device is in contact with the cable. After a long working time, the contact surface has poor contact and...

AI Technical Summary

Problems solved by technology

[0003] During the cable annealing process of the contact brush transmission high-current annealing machine, the electrode wheel inside the device is in contact with the cable. After a long working time, the contact surface has poor contact and occasionally sparks, which will cause the cable surface to burn and affect the cable surface. quality, and during the long-term working process of the electrode wheel, the upper resistance of the electrode wheel will be inconsistent. A slight increase in resistance will cause the cable to be stretched, and the formed wire diameter of the cable will be inconsistent before and after, and this section of cable will become a defective product.
