Problems solved by technology

The traditional production method in China is to weld or rivet multiple pieces after stamping a single piece. Most of the materials are ordinary carbon steel plates. Because the pieces are not related to each other, there are more or less gaps in the material between each piece. Differences in the material itself or man-made, and due to the influence of small pressure during welding or riveting, gaps are prone to appear between the sheets of the iron core, which directly affect the performance of the generator; The material utilization rate in the stator core production method is quite low (only 20-30%), and its corners and middle circles are all washed out

Embodiment 1

[0031] Such as Figure 1 ~ Figure 4 As shown, the manufacturing method of the winding type automobile generator stator core is:

[0032] 1. Uncoiling and leveling, put the 1.0 mm thick disc-shaped steel strip on the uncoiler, adjust the leveling speed of the leveling machine according to the speed of the punching machine and the step distance of the die and make it match, and the uncoiling is driven by the leveling machine The machine is running, and the steel belt is opened sequentially from the outer circle;

[0033] 2. Stamping, using a press for stamping, the steel strip is stamped in three steps through a progressive stamping die, and then divided into two continuous toothed strips that are not connected to each other and have the same size. The first step is to stamp the steel The R arc with the end, the second step of stamping the U-shaped end hole, and the third step of stamping the side hole. The stamping die is a cemented carbide mosaic structure. The pressure of th...

Abstract

The invented manufacturing method includes following steps. (1) Uncoiling, flattening steel strip. (2) After three steps of stamping, through machine press and upgrading stamping mold, the steel strip is divided into two continuous jugged strips in same size. (3) Two strips of iron core are processed as two rounded helicoids loose iron core separated from the strips by wrapping machine. (4) With being located in mould, welding the said loose iron core obtains integral stator iron core having regular teeth and specific size. (5) Welded iron core put into shaping device through oil press is shaped. (6) Finishing step. The method provides advantages of high utilization rate, good quality of product, low price, and simple structure of equipment.

Description

technical field [0001] The invention relates to a manufacturing method, a winding machine and a shaping device for a winding type automobile generator stator core. Background technique [0002] The stator core is a key component in an automobile generator, and its quality will directly affect the overall performance of the generator. The traditional production method in China is to weld or rivet multiple pieces after stamping a single piece. Most of the materials are ordinary carbon steel plates. Because the pieces are not related to each other, there are more or less gaps in the material between each piece. Differences in the material itself or man-made, and due to the influence of small pressure during welding or riveting, gaps are prone to appear between the sheets of the iron core, which directly affect the performance of the generator; The utilization ratio of material in the production method of type stator core is quite low (only 20-30%), and its corner and middle ci...
