Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] The accompanying drawing is a schematic sectional view of a spinning poly-V-belt pulley of the present invention.

[0031] A steel plate spinning multi-ribbed motor pulley, comprising a wheel surface 100, spokes 200, and a central inner hole 300. The wheel face 100 and the spokes 200 are a spinning integral structure. The parts are made of 6mm sheet metal, and are formed through blanking, spinning bosses, spinning V-shaped grooves, punching and other main processes. The wheel surface 100 and the spokes 200 are connected as one, which changes the traditional welding connection method. , to ensure the strength of the pulley, and the wheel surface 100 and the spokes 200 are center-symmetric structures, the tooth surface finish is good, the surface structure is dense and wear-resistant, the service life of the pulley is improved, and the product qualifica...

Abstract

The invention discloses a steel plate spinning multi-wedge motor belt wheel and a spinning method of the steel plate spinning multi-wedge motor belt wheel, and belongs to the technical field of transmission devices and manufacturing methods. The steel plate spinning multi-wedge motor belt wheel comprises a wheel face, a spoke and a center inner hole, wherein the wheel face and the spoke are of an integrated spinning structure and are each of a central symmetry structure; the wheel face is provided with a set of V-shaped grooves which are integrally connected; the two sides of the wheel face are provided with convex edges higher than the V-shaped grooves; the wheel face and the spoke are perpendicularly connected, and the axial section formed by the wheel face and the spoke is in a cantilever shape. The spinning method of the steel plate spinning multi-wedge motor belt wheel includes the first step of blanking and punching, the second step of spinning of a boss, the third step of preformation spinning and the fourth step of spinning molding. The belt wheel is of the integrated spinning structure and is good in mechanical performance of materials, products are not prone to deformation, product size accuracy is higher, the service life of the belt wheel is long, the product production cost is low, no precision cutting machining machine tool is needed, and cost input is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of a transmission device and a preparation method thereof, and in particular relates to a steel plate spinning multi-rib motor pulley and a spinning method thereof. Background technique [0002] As an important mechanical transmission component, V-groove pulleys are widely used in automobiles and agricultural machinery. [0003] The traditional manufacturing process of the pulley is to use the casting and forging process to make the rough blank, and then make it through cutting. This process method results in large material consumption, low productivity, heavy pulley weight, and unsatisfactory groove surface finish. The parts of the pulley are welded, which has low strength and is easy to break during use. Contents of the invention [0004] The object of the present invention is to overcome the defects and deficiencies mentioned above, and provide a kind of steel plate spinning multi-ribbed motor pulley....
