Abstract

The invention provides an electroplastic-effect-based elastic particle medium assisted electromagnetic forming device and forming method for a light-alloy miniature complex component and belongs to the field of metal material processing and forming. By means of the device and method, the problem that according to existing miniature complex component forming methods, both the workpiece quality andthe precision cannot be taken into account simultaneously is solved. According to the device, a light-alloy plate is clamped between an elastic particle medium cavity and a die, an electroplastic unitmakes the plate be subjected to the electroplastic effect, a temperature measurement unit measures the plate surface temperature, and an impact unit withstands electromagnetic force from an electromagnetic pulse generating unit and applies impact force to the plate through an elastic particle medium to make the plate be attached to a forming cavity of the die. The method comprises the steps thatthrough the electroplastic unit, the plate is subjected to the electroplastic effect, through cooperation between the electroplastic unit and the temperature measurement unit, the plate surface temperature is controlled, through the electromagnetic pulse generating unit, the electromagnetic force is applied on the impact unit, and through cooperation between the impact unit and the elastic particle medium, the plate is made to be attached to the forming cavity.

Description

technical field [0001] The invention relates to an electromagnetic forming device and a forming method of light alloy miniature complex components, belonging to the field of metal material processing and forming. Background technique [0002] In recent years, complex micro-components have been widely used in fields such as medical devices and aerospace. However, with the continuous development and progress of science and technology, many application fields of complex micro-components also put forward higher requirements for their quality and precision. [0003] The existing forming methods of complex micro-components mainly include forming methods such as micro-drawing, micro-extrusion and micro-bending developed on the basis of traditional plastic forming. However, these forming methods are easy to cause irreversible production defects such as cracks in complex micro-components, resulting in low workpiece yield. [0004] In order to solve the above problems, some scholars...
