Feeding and fixing core device for steel ball rolling mill production line

Abstract

The invention relates a feeding and fixing core device for steel ball rolling mill production line. The device comprises an intermediate frequency heating furnace assembly, a feeding roller wheel assembly and a fixed core assembly, wherein the intermediate frequency heating furnace assembly comprises at least one heating coil mechanism, the feeding roller wheel assembly is arranged at the input end and / or the output end of the medium-frequency heating furnace assembly, the feeding roller wheel assembly comprises a rotatable roller wheel, a circle of groove I for supporting bar materials is formed in the circumferential surface of the roller wheel, the fixed core assembly is arranged between the adjacent heating coil mechanisms and comprises a sliding block and a groove II arranged above the sliding block, the groove II is provided with a third inclined surface and a fourth inclined surface which are formed on the surface of the sliding block, and when the bar materials are placed in the groove II, the bar materials is correspondingly simultaneously in contact with the third inclined surface and the fourth inclined surface. According to the feeding and fixing core device for the steel ball rolling mill production line, the material throwing problem of the bar materials of a rolling mill can be solved, the gap distance between the adjacent heating coil mechanisms can be reduced, and the heat loss of the bar materials can be reduced.

Description

technical field [0001] The invention belongs to the field of automatic production equipment, and relates to a bar feeding device, in particular to a feeding and centering device used in a steel ball rolling mill production line, which can be used in steel ball rolling production. Background technique [0002] The existing small and medium-sized wear-resistant steel balls are all produced by hot rolling process, and most of them are added by intermediate frequency induction. During the production process, the most prominent problem is that when the bar is rotated, it is easy to be out of concentricity, which will lead to material throwing, damage the intermediate frequency heating coil mechanism, and when the bar is rotating, it is easy to contact the coil and damage the insulation, and the ignition will break down the silicon controlled rectifier, which has potential safety hazards and The consumption of accessories is high and the cost increases. Therefore urgently need to...
