Repairing device for surface abrasion of large wheel fixing table base and repairing process

Abstract

The invention discloses a repairing device for surface abrasion of a large wheel fixing table base. The repairing device comprises a welding robot, a structural part supporting platform, a heating device arranged on the structural part supporting platform, a mechanical arm base and a mechanical arm lifting adjusting device; the mechanical arm lifting adjusting device is movably arranged on the mechanical arm base and can lift for adjustment on the mechanical arm base; and a base of the welding robot is arranged on the mechanical arm lifting adjusting device. A repairing process based on the repairing device for the surface abrasion of the large wheel fixing table base is further disclosed. The repairing process is implemented, through welding verification, welding repair of the abrasion of the large wheel fixing table base can be rapidly implemented, the purchase cost is reduced, the long-time procedure shutdown loss is reduced, and a guarantee is provided for reasonably grouping and producing various domestic and overseas wheels.

Description

technical field [0001] The invention belongs to the field of welding technology, and relates to a welding repair device and a repair process for the surface wear of a base of a large wheel fixing platform. Background technique [0002] Masteel Rail Transit Material Technology Co., Ltd. is an important train wheel production base in my country. It is the largest wheel manufacturer in Asia and the only company in China that can produce passenger car wheels with speeds above 120Km / h. The research and development of heavy-duty wheels has reached the international advanced level. . At present, there are two wheel production lines with an annual production capacity of 800,000 pieces. The second line of wheels is a multi-variety rolling production line. The core rolling process of wheels: heating steel billet--removing phosphorus from the whole surface--90MN wheel preforming--clamping by mobile manipulator--rolling mill rolling--clamping by mobile manipulator- -50MN positioning fo...

AI Technical Summary

Problems solved by technology

The working principle of 50MN positioning forming punching is to put the hot wheel after rolling in the rolling mill on the abrasive tool installed on the base of the wheel fixing table, and the punching mandrel is connected and fixed on the top of the rolling mill and fastened with the movable beam, and is driven up and down by the rolling mill , the wheel is punched and formed, and the mold for punching and forming is installed on the base of the large wheel fixing table designed and manufactured. The base of the large wheel fixing table is installed on the base of the hydraulic press and bears the rolling pressure and the weight of the equipment body. Due to the long-term hydraulic press. Stable rolling and the wear of the base surface in contact with the bottom of the fixed table base will cause the mold to wear on the surface of the large wheel fixed table base, which will affect the installation accuracy and seriously affect the wheel rolling size. If a new large wheel fixed table base is replaced, it will not only require hundreds The cost of spare parts is 10,000 yuan, and because there are no spare parts, the cycle of purchasing and processing new spare parts is long, which will inevitably affect production
