The invention discloses a production process for manufacturing a conductor rotor through powder fusion welding. The production process comprises the following steps that (1) the surface of a conductor cylinder is cleaned, and wiping or airing are carried out at normal temperature; (2) metal powder is molten by a hot melting welding gun, reciprocating motion on the inner circumferential surface of the conductor cylinder is performed in the axial direction, the molten metal powder is subjected to build up welding on the inner circumferential surface of the conductor cylinder, after build up welding to a certain thickness, the conductor cylinder is driven to rotate by a stepping amount by a positioner to perform next welding, welding of a circle on the inner circumferential surface of the conductor cylinder is completed circularly, and a layer of conductor ring is formed; (3) a machine is stopped, the conductor cylinder and the conductor ring are taken down, and cooling is carried out to room temperature; and (4) the conductor cylinder and the conductor ring are processed by using a cutting machine tool to enable the conductor cylinder and the conductor ring to reach the size required by a drawing so as to form an integral conductor rotor. The production process is low in precision requirement, small in machining amount, high in efficiency, convenient to assemble, low in cost and suitable for popularization and application, and heat conduction is facilitated through the structure.
Description
technical field [0001] The invention relates to the technical field of permanent magnet speed regulation, in particular to a powder fusion welding production process of a conductor rotor. Background technique [0002] The permanent magnet governor is a device that uses magnetic force to achieve power transmission and speed regulation. It has the characteristics of simple structure, high reliability, and strong environmental adaptability. The permanent magnet governor is mainly composed of a conductor rotor and a permanent magnet rotor. The conductor rotor is mainly composed of a conductor ring and a conductor cylinder. The precision requirement is high, a lot of waste is produced, the production process is complex, the cycle is long, the cost is high, and it affects the heat conduction of the conductor part, which is not conducive to heat dissipation. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art...
