Abstract

The invention belongs to the technical field of claw preparation, aims to overcome the defect that the claw pole shaping process in the prior art reduces the height of claw teeth and deforms work pieces, and provides a lateral shaping process for hybrid excitation claw poles. The outer side of a lower die holder of a shaping mold is equipped with lateral sliders matched with lower concave dies on the lower die holder, a claw pole is fixed to the mold, force is applied to the lateral sliders along the radial direction of the lower die holder to make the lateral sliders move to the lower die holder and match the lower concave dies, and force along the radial direction of the lower die holder continues to be applied to the lateral sliders to shape claw teeth and wings of the claw pole. The beneficial effects are as follows: the wings of a hybrid excitation claw pole are shaped through lateral force, and the wings can be shaped under the action of a small force; materials flow laterally, the flow length is small, and the adverse impact of friction to shaping during claw pole shaping under forward extrusion can be reduced; moreover, there is no need to open a material accommodating slot during hot forging, the forging process is simplified, and the product performance is improved.

Description

technical field

[0001] The invention belongs to the technical field of claw pole preparation, and in particular relates to a shaping process of hybrid excitation claw poles. Background technique

[0002] In order to increase the power generation of the automobile generator, a hybrid excitation claw pole 12 generator has been developed. This kind of hybrid excitation claw pole 12 generator needs to place a permanent magnet block on the claw tooth 121 side of the claw pole 12 . In order to locate the permanent magnet block, it is necessary to form wings 122 on the sides of the claw teeth 121, such as figure 1 As shown, the surface of the wings 122 and the sides of the claw teeth 121 form two mutually perpendicular planes for positioning the permanent magnet block. Due to the complex shape of the claw teeth 121, the machining of these two vertical planes is time-consuming and laborious. Shaping methods to shape. The method currently adopted is to form larger rounded corners a...
