Problems solved by technology

[0005] However, the stator core winding devices disclosed in the above two patents also have the following technical defects: 1. The yoke of the toothed belt material is a sliding friction in the forming groove, and its frictional resistance is relatively large, which is not conducive to tooth profile The bending deformation of the strip material; 2. There is no forming groove for secondary winding

Abstract

The invention relates to a stator core winding device. A molding groove of the stator core winding device is divided into a feeding groove section used for guiding a fed material and a variable-diameter molding groove section used for secondary coiling molding, wherein the feeding groove section and the variable-diameter molding groove section are connected through a detaching pin; a molding roller used for reducing friction is arranged at the bottom of the feeding groove section; and the curvature of a molding working surface of the variable-diameter molding groove section is gradually increased. The friction between a yoke part of a small toothed belt and the molding groove can be effectively reduced through the device, deformation resistance in a coiling process is reduced, the toothed belt is gradient in the device, the feasible range of stator core superposing is expanded, and the device can be popularized from a vehicle power generator with a small ratio of the width to outer diameter of the yoke part to an ordinary motor with a high ratio of the width to outer diameter of the yoke part.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, more specifically to a stator core winding device. Background technique [0002] It has become a new process technology to manufacture motor cores by using the spiral winding superposition method. This process technology breaks through the traditional punching process, and has great breakthroughs in reducing consumables and improving processing efficiency. [0003] For example, the patent No. ZLZL92239880.1 is a small generator stator core double-head winding device. Its characteristics are: one winding device has two winding heads, and the horizontal winding is changed to vertical winding, eliminating the need for a turning mechanism. And added adjustable gap, anti-interference entrance and other designs, with compact structure, low cost, small footprint, high single-machine work rate, strong adaptability to changes in steel strip thickness, smooth operation, good chip forming qual...
