Material shelf pushing and pulling device for cable annealing

Abstract

The invention provides a material shelf pushing and pulling device for cable annealing. The material shelf pushing and pulling device for cable annealing comprises a material shelf and a hydraulic pushing and pulling device. Multiple parallel stop blocks are arranged at the bottom of the material shelf. The hydraulic pushing and pulling device is arranged below the material shelf and comprises an oil cylinder, a supporting block and a steering block. The axis of the oil cylinder is perpendicular to the stop blocks. The supporting block is arranged at the end of a piston rod of the oil cylinder. The middle of the supporting block is hinged to the middle of the steering block. Two pin holes are formed below the hinging portion on the side face where the supporting block is hinged to the steering block. The upper end of the steering block is higher than the supporting block and the bottoms of the stop blocks of the material shelf. The lower end of the steering block is lower than the positions of the two pin holes. According to the material shelf pushing and pulling device for cable annealing, the structure is simple, the moving distance of the material shelf is long, the oil cylinder is used for pushing the material shelf, operation is convenient, labor intensity of workers is relieved, and production efficiency is improved.

Description

technical field [0001] The invention relates to a conveying supporting equipment for the annealing of bare copper conductors of wires and cables, in particular to a material rack push-pull device for cable annealing. Background technique [0002] At present, in the annealing process of wires and cables to bare copper conductors, in order to prevent quality problems such as three damages, the bare copper conductors are put into iron pans, and after the multiple iron pans are combined with a material rack, a push-pull device is used to Move the material rack horizontally into the horizontal annealing furnace for annealing. The annealing furnaces such as pit type, bell type and pit type do not use this kind of device, but basically adopt the method of hoisting, and put them into the annealing furnace for annealing. [0003] For the material rack carrying the iron plate, it needs to be moved by external force; the moving method is to drive the material rack to move by rolling f...

AI Technical Summary

Problems solved by technology

[0004] The moving method of using each roller to output power to drive the material rack has the following defects: the weight of the material on the material rack is small, suitable for continuous annealing furnaces, and not suitable for horizontal annealing furnaces for feeding and discharging each furnace Way

[0005] In the method of pushing the bracket to move on the rollers by external force, the patent "a conveying device" application number is CN201120491438.6 and the patent "a push-pull device" application number is CN201120490348.5. The working method of pushing the material rack , not suitable for the annealing of bare copper conductors in the wire and cable industry; the material rack and the push rod are connected by hinges, and the pushing and pulling distance is short, not the way of pushing and pulling the material rack equipped with iron plates in sections; moreover, its complex structure
