Process for manufacturing frame type coil of hydro-generator stator

Abstract

The invention provides a process for manufacturing a frame type coil of a hydro-generator stator. The process is characterized by comprising five steps of: (1) retrieving a design plan and carrying out modeling of the frame-type coil; (2) simulating stator assembly by using three-dimensional software; (3) three-dimensional molding; (4) simulation processing; and (5) assembling a mold assembly. The process provided by the invention solves a problem of interference between the frame-type coil of the hydro-generator stator and stator assembling caused by a design and tooling problem in the process of manufacturing the frame-type coil of the hydro-generator stator, the efficiency in designing and manufacturing the frame-type coil of the hydro-generator stator by using the three-dimensional software is greatly improved, the error probability is extremely small, the three-dimensional sense is strong, designers are not easy to read drawings mistakenly, and the like. In addition, contour machining can be carried out accurately by using a software-carried CAM (simulation processing) function, the manufactured workpiece is precise and does not need to be repaired manually, thereby shortening the production period, improving the production efficiency, and avoiding a phenomenon of assembling interferences.

Description

technical field [0001] The invention belongs to the technical field of hydraulic turbine manufacturing and processing, and in particular relates to a manufacturing process for a stator frame coil of a hydraulic generator. Background technique [0002] In the prior art, the manufacturing process of the stator frame coil of the hydraulic generator is relatively complicated. First, the designer of the hydro-generator designs and issues the plan according to the relevant parameters, and then the relevant craftsman produces the mold tooling according to the relevant requirements of the design drawings, and then transfers to the workshop to make the rough tooling according to the drawings of each part of the mold, and finally manufactures the coil according to the tooling mold. According to the current situation, wire cutting is mostly used in the production of mold lines, and then the mold is manually repaired, especially the end is completely handmade. During the subsequent ass...
