A Roller Head Fracture Melting and Casting Repair Device

Abstract

The invention relates to roll recycling, in particular to a roll head fracture melting and casting repair device. The technical problem to be solved by the present invention is to provide a roll head fracture melting and casting repairing device. A roll head fracture melting and casting repair device, including an automatic feeding ring cutting mechanism, a gantry, a recasting pouring reconstruction mechanism, a gearbox, a speed change wheel set, a control display and a roll head broken roll; the top right of the automatic feeding ring cutting mechanism The part is meshed with the recasting and pouring transformation mechanism. The invention achieves the improvement of the fitting degree and rigidity requirements between the cast prosthetic body and the original body, prevents re-fracture caused by direct casting due to weak connection, and at the same time breaks the roll head after re-casting on the surface of the roll The correction of the excess amount reduces the processing time when all the broken rolls are melted and recycled, and only the ends of the broken rolls are recycled, which solves the processing time and saves processing energy consumption.

Description

technical field [0001] The invention relates to roll recycling, in particular to a roll head fracture melting and casting repair device. Background technique [0002] The roll is the main working part that causes continuous plastic deformation of the metal on the rolling mill. The roll is mainly composed of three parts: the roll body, the roll neck and the shaft head. Among them, the roll body is the middle part of the roll that actually participates in rolling the metal; the roll neck is installed on the In the bearing, the rolling force is transmitted to the frame through the bearing seat and the pressing device; the shaft head is connected with the gear seat through the connecting shaft to transmit the rotational torque of the motor to the roll, so that the roll rotates and rolls metal. [0003] Prior art Chinese patent CN110216270A aims at the problem that the existing roll neck defect treatment method is usually to scrap the entire roll, and discloses a roll repair meth...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the lack of bonding between the casting body and the casting body, and the rigid condition is greatly reduced, the present invention is easily broken during the production process again, and the welded roll neck and roll head are likely to deviate from the axis, and the welding effect cannot reach the roll. Due to the high-strength pressure requirements in use, the rolls are easy to break during high-speed rotation, and the cracking and separation will cause the equipment to stop, damage the equipment, and cause production safety accidents. The technical problem to be solved by the present invention is to provide a roll head fracture Casting repair device
