A composite manufacturing method for connecting and forming metal plate parts based on high-speed impact

Abstract

The invention belongs to the relevant field of machining and forming of plate components, and discloses a metal plate component connection and forming composite manufacturing method based on high-speed impact. The method comprises the following steps that a reinforcing plate is placed on a mould, and a substrate is arranged above the reinforcing plate; a circuit loop is provided for the substrate, and an aluminum foil is used as a material source for generating gasification drive at the same time; current flows through the aluminum foil and gasification occurs, and generated local high-pressure air mass drives the substrate to move downwards at a high speed and hit the reinforcing plate; and the reinforcing plate is connected with the substrate at an impact position, and with the continuous impact and final stop of the impact, the reinforcing plate and the substrate are gradually connected and formed into a whole in the mould until the whole composite manufacturing process is completed. The invention also discloses a corresponding metal plate product. Through the method, the forming limit of plate component can be improved, the machining defects such as excessive strain at corners and connection with the mould can be reduced advantageously, and the method has the advantages of less required processes, high forming precision and efficiency, convenience in operation and control, and the like.

Description

technical field [0001] The invention belongs to the field related to the processing and forming of plate components, and more specifically relates to a composite manufacturing method for connecting and forming metal plate components based on high-speed impact. Background technique [0002] With the rapid development of modern industries such as aviation, aerospace, automobiles, electronics, and ships, metal components must not only meet the mechanical requirements, but also meet the requirements of electrical conductivity, thermal conductivity, wear resistance, corrosion resistance, and lightweight. . At the same time, as the engineering structure becomes more and more complex, there are special requirements for the performance of local areas. Therefore, it is difficult for a single material to meet all requirements at the same time, and composite processing of connecting and forming materials with different properties is required. For example, the same or dissimilar metals...
