Magnetic medium auxiliary tailor-welded blank drawing forming device and forming method

Abstract

The invention provides a magnetic medium auxiliary tailor-welded blank drawing forming device and forming method. According to the magnetic medium auxiliary tailor-welded blank drawing forming device,the blank holder force is controlled through a hydrauilc control system, a magnetic medium feeding cylinder is used for feeding magnetic medium into a female die cavity through a liquid hole, a sliding coil assembly penetrates through a plurality of core rods installed on a support to be in sliding connection with the support, by independantly controlling the electric current of coils, changing the relative positions of the coils and controlling the number of the coils on the two sides of the forming device, the strength of an area magnetic field is adjusted, the rheological property and thedistribution state of the magnetic medium are changed, and accordingly different force transmission effects are achieved; a plunger is arranged to regulate the extrusion force of the magnetic medium in the forming process, drawing forming is guaranteed to successfully proceed, and a chain structure is not damaged; and by means of the method, the actual different personalized customization requirement can be met according to forming requirements of different portions of a component, the area magnetic field is controlled in multiple dimensions, the magnetic medium auxiliary forming effect is optimized, and the magnetic medium auxiliary tailor-welded blank drawing forming device and forming method are suitbale for the field of magentic medium auxiliary drawing forming.

Description

technical field [0001] The invention relates to a soft mold deep-drawing forming process method of a tailor-welded blank, in particular to a magnetic-medium-assisted tailor-welded blank deep-drawing forming device and method, and belongs to the technical field of tailor-welded blank forming. Background technique [0002] With the increasing requirements for the formability and serviceability of materials required for parts and components in cutting-edge fields such as advanced manufacturing technology, sheet metal components that are easy to achieve various requirements such as lightweight, high precision, and low consumption have been widely used. Therefore, It has promoted the continuous innovation and rapid development of sheet metal forming technology. [0003] Tailored welded blanks are made of two or more sheets of different thickness, material or surface coating, which are welded as a whole after blanking, which can meet the requirements of different parts and perform...
