Lightweight motor shaft forming equipment and method

Abstract

The light-weight motor shaft forming equipment comprises a workbench and a motor, a supporting seat is fixedly connected to the center position of the workbench, a cylindrical and transversely-arranged rotary swaging seat is fixedly connected to the supporting seat, a cylindrical working groove is concentrically formed in one side of the rotary swaging seat, and a rotary swaging groove is formed in the other side of the rotary swaging seat; an annular groove with the T-shaped section is concentrically formed in the groove wall of the working groove, and a connecting sliding ring with the T-shaped section is slidably connected into the annular groove. The clamping blocks in all the clamping grooves move towards the axis direction at the same time under extrusion and pushing of the arc grooves to the pin columns, a pipe and a core rod are clamped and fixed, the pipe and a forging opening are kept coaxial, the machining quality of the pipe is guaranteed, rotary forging and feeding are synchronously carried out under driving of the same motor, the synchronous coordination is better, and the machining efficiency is improved. And meanwhile, the impact forging frequency can be rapidly adjusted according to needs, so that the application range of the equipment is wider.

Description

technical field [0001] The invention relates to the technical field of shaft parts processing, in particular to a lightweight motor shaft forming equipment and method. Background technique [0002] The shaft is an important part of the motor. As the link of electromechanical energy conversion between the motor and the equipment, it supports the rotating parts, transmits the torque and determines the relative position of the rotating parts to the stator. Therefore, the motor shaft must have reliable strength and rigidity , to ensure the realization of preset design functions. [0003] For some large motors, in order to provide a large torque, the diameter of the motor shaft will increase accordingly, and the weight of the shaft will increase accordingly. These increases in weight will have a greater adverse effect on its power transmission and rotation. For the overall quality of the shaft, most of the existing production and processing adopt the method of shaft drilling, wh...

Problems solved by technology

[0003] For some large motors, in order to provide a large torque, the diameter of the motor shaft will increase accordingly, and the weight of the shaft will increase accordingly. These increases in weight will have a greater adverse effect on its power transmission and rotation. For the overall quality of the shaft, most of the existing production and processing adopt the method of shaft drilling, which wastes more materials, reduces the utilization rate of materials, and requires a lot of drilling time, which increases the production cost of the motor shaft , for this purpose, we propose a lightweight motor shaft forming equipment and method
