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 in particular relates to a device and method for manufacturing a stepped tubular part driven by multidirectional magnetic field force. Background technique [0002] The existing forming method of stepped cylindrical parts is deep drawing, which adopts a set of forming tooling and presses with convex and concave dies. It is difficult to process high-strength and difficult-to-form metal materials due to tearing. Contents of the invention [0003] In order to solve the above problems, the present invention provides a device and method for manufacturing stepped cylindrical parts driven by multidirectional magnetic force, which can avoid wrinkling, instability and cracking when forming stepped cylindrical parts, and improve the drawing height And product quality, simplify the forming process. [0004] The present invention provides a device for manufacturing stepped cyl...
