Description

Technical Field

[0001] The utility model belongs to the technical field related to component improvement of a multi-head wire drawing annealing machine, and particularly relates to an annealing shaft assembly of the multi-head wire drawing annealing machine which can prevent bearings from burning out in a short time. Background Art

[0002] When the multi-head wire drawing annealing machine is working, the copper wire conducts high current and low voltage through the annealing wheel on the annealing shaft to generate a high temperature of 550-600℃, thereby achieving annealing and softening; when working, due to the high-speed operation of the annealing shaft, the first bearing and the second bearing thereon will generate a certain temperature themselves; at the same time, the carbon brush copper wheel is a conductive wheel, and the friction between the carbon brush and the copper wheel causes the carbon brush copper wheel to generate high temperature. The two heat sources cause the temperatures of the carbon brush copper wheel and the annealing wheel to be very high, and the high temperature will be transmitted through the axis to the first bearing close to the carbon brush copper wheel and the second bearing close to the annealing wheel, and the temperature that the first bearing and the second bearing can usually withstand does not exceed 100℃; with the increase in the number of wires and the diameter of the wires passed by the annealing wheel, the heat generated increases year-on-year. When the temperature exceeds the temperature that the bearing can withstand, the bearing will soon burn out.

[0003] To this end, we have developed an annealing shaft assembly for a multi-head wire drawing annealing machine that can prevent the bearings from burning out in a short period of time. Summary of the invention
