Device and method based on electrostatic force gradual advancing and push-and-pull composite forming and used for large aluminum alloy part

Abstract

The invention relates to the technical field of aluminum alloy forming and provides a device and method based on electrostatic force gradual advancing and push-and-pull composite forming and used fora large aluminum alloy part. The device comprises pressing plates, ejecting plates, a die and solenoid coils. The pressing plates are located above the ejecting plates and used for fixing the aluminumalloy part to the ejecting plates. The solenoid coils are arranged above the die, and the aluminum alloy part is arranged between the die and the solenoid coils. The method comprises the following steps that (1), the aluminum alloy part is put on the ejecting plates and fixed through the pressing plates; (2) the position of the die is adjusted, and the die is arranged below the aluminum alloy part to be formed; and (3), the solenoid coils are electrified, and the solenoid coils and the die located below the aluminum alloy part interact to complete forming of the aluminum alloy part. Accordingto the device and method based on electrostatic force gradual advancing and push-and-pull composite forming and used for the large aluminum alloy part, electrostatic force gradual advancing forming and the traditional push-and-pull technology are combined, thinning of walls can be obviously restrained compared with traditional spinning forming, and wrinkling can be obviously restrained compared with traditional stamping.

Description

technical field [0001] The invention relates to the technical field of forming aluminum alloy parts, in particular to a device and method for progressive push-pull composite forming of large aluminum alloy parts based on electrostatic force. Background technique [0002] The deformation ability of aluminum alloy at room temperature is poor. During the forming process of large aluminum alloy parts, the wall thickness of aluminum alloy parts is easy to be thinned when spinning forming is used; when traditional stamping is used, the surface of aluminum alloy parts is prone to wrinkling. . This leads to lower forming precision of the aluminum alloy sheet. Contents of the invention [0003] Based on the above background, the present invention provides a device and method for progressive push-pull composite forming of large aluminum alloy parts based on electrostatic force. [0004] The present invention adopts following technical scheme: [0005] A progressive push-pull comp...

[0002] The deformation ability of aluminum alloy at room temperature is poor. During the forming process of large aluminum alloy parts, the wall thickness of aluminum alloy parts is easy to be thinned when spinning forming is used; when traditional stamping is used, the surface of aluminum alloy parts is prone to wrinkling.

This leads to the lower forming precision of aluminum alloy sheet
