Ladder-shaped cylindrical part producing equipment and method based on magnetic field force drive

Abstract

The invention discloses ladder-shaped cylindrical part producing equipment and method based on magnetic field force drive. The ladder-shaped cylindrical part producing equipment includes a first typedevice and a second type device; the first type device includes a concave mold with a ladder-shaped inner cavity, pressing parts are arranged on the upper portion of the side wall of the concave mold,upper-end-portion reducing coils and lower-end-portion reducing coils are arranged in the pressing parts and the side wall of the concave mold respectively, and multi-layer panel spiral axial drawingcoils for generating axial press-down electromagnetic force on to-be-produced plates to form cone-shaped parts are further arranged above the inner cavity of concave mold; the second type device includes a convex mold with a ladder-shaped surface, pressing parts are arranged at the periphery of the upper portion of the convex mold, and multi-layer panel spiral radial-axial drawing coils are further arranged above the convex mold. By the adoption of the ladder-shaped cylindrical part producing equipment and method based on the magnetic field force drive, wrinkling, unstability and tearing canbe avoided when ladder-shaped cylindrical parts are shaped, the drawing height and the quality of products are improved, and a shaping technology is 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 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 magnetic field force, which can avoid wrinkling, instability and cracking when forming stepped cylindrical parts, and improve the drawing height and product quality. Quality, simplified forming process. [0004] The invention provides a step-shaped cylindrical piece manufacturing equipment driven by m...
