A method of manufacturing an inducer provided with a shaft sleeve

Abstract

The invention discloses a manufacturing method of an induction wheel with a shaft sleeve. The manufacturing method comprises the following steps: A, determining a positioning welding position of the shaft sleeve of the induction wheel on a workbench; B, installing the workbench on a machine body; C, processing a molded body; D, segmenting and processing the induction wheel; and E, ejecting the induction wheel. According to the manufacturing method, the vertically arranged shaft sleeve is limited at the positioning welding position of the workbench, the position of a circular truncated cone body is determined through the position of the shaft sleeve, the circular truncated cone body and the shaft sleeve are welded in a matched mode, the position of a hub is determined through the position of the circular truncated cone body, a base is connected with the bottom of the hub in a threaded mode, the top of the circular truncated cone body and the bottom of the base are welded in a matched mode, and the required induction wheel can be segmented and processed, so that the connection strength of the induction wheel and the pump shaft is met; and moreover, the shaft sleeve, the circular truncated cone body and the base are vertically stacked and welded to each other, so that the phenomenon that the connecting surface is misaligned due to self-gravity is avoided, the welding quality is improved, the welding difficulty is reduced, and meanwhile, the induction wheel obtained by machining is facilitated.

Description

technical field [0001] The invention belongs to the technical field of inducer manufacturing, and in particular relates to a method for manufacturing an inducer provided with a shaft sleeve. Background technique [0002] The inducer is a complex fluid device with good corrosion resistance and cavitation resistance, and is widely used in turbomachinery in aerospace, machinery, aviation, chemical and other industries. The inducer is integrally formed by the hub and the blades. The hub is a rotating body, and the blades are curved surfaces. There is a rounded transition surface between the blades and the hub. [0003] The traditional induction wheel production generally adopts the method of trimming after casting, but with the development of the design concept, the shape of the working surface of the induction wheel is becoming more and more complicated, the difficulty of mold manufacturing is relatively large, the process is complicated, and the accuracy of the blade is diffic...
