A device and method for manufacturing stepped cylindrical parts based on multi-directional magnetic force drive

Abstract

The invention discloses a device and method for manufacturing a stepped cylindrical part based on multi-directional magnetic field force driving. The device comprises a female die with a stepped innercavity; pressing parts are arranged at the upper part of the side wall of the female die and are used for being coordinated with the side wall of the female die to fix a plate to be manufactured; upper end part reducing coils and lower end part reducing coils are arranged in the pressing parts and the side wall of the female die correspondingly and are used for generating the radial inward compression electromagnetic force on the plate to be manufactured; a reserved space is formed in the upper part of the inner cavity of the female die and is internally provided with multi-layer slab spiralaxial deep drawing coils or multi-layer slab spiral radial-axial deep drawing coils, wherein the multi-layer slab spiral axial deep drawing coils are used for generating the axial downward piezoelectric magnetic force on the plate to be manufactured so as to form a conical part, and the multi-layer slab spiral radial-axial deep drawing coils are used for simultaneously generating the radial inwardcompression electromagnetic force and the axial downward piezoelectric magnetic force on the conical part. The device and the method has the advantages that wrinkling instability and pull cracks in forming process of the stepped cylindrical part can be avoided, the drawing height and the product quality can be improved, and the forming process can be simplified.

Description

Technical field [0001] The invention belongs to the technical field of material processing and forming, and particularly relates to a device and method for manufacturing a stepped cylindrical member driven by a multi-directional magnetic field force. Background technique [0002] The existing forming method of stepped cylindrical parts is deep drawing. A set of forming tools and presses with convex and concave molds are used. The production cost is high, the cycle is long, and wrinkles are prone to appear in the drawing process, that is, instability, and even It is difficult to process high-strength and difficult-to-shape metal materials due to tensile cracking. Summary of the invention [0003] In order to solve the above-mentioned problems, the present invention provides a stepped cylindrical member manufacturing device and method based on multi-directional magnetic field force driving, which can avoid wrinkling, instability and tearing when the stepped cylindrical member is for...
