A Repairing Technology for Surface Wear of Large Wheel Fixing Platform Base

Abstract

The invention discloses a repairing device for surface wear of a large wheel fixing platform base, which comprises a welding robot, a supporting platform for structural parts, a heating device arranged on the supporting platform for structural parts, a manipulator base and a manipulator lifting adjustment device; the manipulator lifting adjustment The device is movably arranged on the base of the manipulator, and can be adjusted up and down on the base of the manipulator; the base of the welding robot is set on the lifting adjustment device of the manipulator. The invention also discloses and implements the repair process of the repair device based on the surface wear of the base of the large-scale wheel fixing platform. Through welding verification, the invention can quickly implement and complete the repair of the wear and tear of the base of the large-scale wheel fixing platform, thereby reducing procurement costs and The loss of long-term process downtime provides a guarantee for the reasonable production of various domestic and foreign wheels.

Description

technical field [0001] The invention belongs to the technical field of welding, and relates to a welding repairing device and a repairing process for the worn surface of a large wheel fixing platform base. Background technique [0002] Maanshan Iron and Steel Rail Transit Material Technology Co., Ltd. is an important train wheel production base in my country, the largest wheel manufacturer in Asia, and the only company in China that can produce passenger car wheels with a speed of 120Km / h or higher. 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 wheel line is a multi-variety rolling production line. The core rolling process of the wheel: heating the steel billet--the overall surface dephosphorization--90MN wheel preforming--mobile manipulator clamping--rolling mill pressing--mobile manipulator clamping- -50MN po...

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
