Manufacturing Method for Belt Axle Connecting Piece of Winch

摘要

The invention provides a belt axle connecting piece of a winch and a manufacturing method in the field of mechanical technologies. The winch comprises a bracket and a belt axle axially arranged on the winch, wherein the belt axle includes three rods arranged along the axial direction. Bundling belts or ropes can be placed within the clearance between any two adjacent rods. The belt axle connecting piece comprises a cylindrical body, with three bent positioning petals arranged at one end of the body. Every two adjacent positioning petals form positioning holes for securing the rods to the bracket. The connecting piece is simple in structure, sturdy, and easy to manufacture.

主权项

1. A method for manufacturing a belt axle connecting piece of a winch, comprising:
(a) stamping a first plate, whereby a plate body is punched from a metallic plate by a stamping device, creating a one-piece plate that is generally rectangular with a plurality of evenly spaced positioning petals (4) along one edge of the first plate; (b) rolling the first plate into a cylindrical shape by a rolling process to form a semi-finished body (3); and (c) bending and molding the positioning petals (4) so that tips (9) of the positioning petals (4) are generally perpendicular to a center axis of the body (3), thereby forming primary positioning grooves (5) between every two adjacent positioning petals (4), the primary positioning grooves (5) capable of securing rods (2) in place on the winch.
