Abstract

The invention discloses a pneumatic flexible electrode heating clamping device for an aluminum alloy member and a quenching forming method, and relates to the technical field of aluminum alloy hot forming. The pneumatic flexible electrode heating clamping device for the aluminum alloy member and the quenching forming method solve the problem that dimensional accuracy of formed parts is reduced tocause distortion of plates due to the fact that quenching stress generated in the heat treatment strengthening process following the warm forming of aluminum alloy in the prior art. The pneumatic flexible electrode heating clamping device for the aluminum alloy member comprises a supporting assembly, a clamping assembly, a connecting rod assembly and a pneumatic assembly, wherein the clamping assembly and the pneumatic assembly are both installed on the supporting assembly, and the connecting rod assembly realizes the up-and-down movement of the clamping assembly through the drive of the pneumatic assembly. The supporting assembly comprises a supporting plate; the clamping assembly comprises a guide pillar fixing plate, guide pillars, an upper sliding connecting plate, disc springs, a lower sliding connecting plate, an insulating plate, a pressing plate, an electrode plate, return springs and correction springs; and a transmission assembly comprises a movable upper pressing plate, a connecting ring and a connecting support. The pneumatic flexible electrode heating clamping device for the aluminum alloy member and the quenching forming method are used for hot forming of the aluminumalloy.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy thermoforming, in particular to a pneumatic flexible electrode heating and clamping device for an aluminum alloy component and a quenching forming method. Background technique [0002] Aluminum alloy has a series of advantages such as low density, high specific strength, high specific stiffness, etc. It is known as a material with important application value in aerospace, transportation and other fields in the 21st century. For heat-treatable aluminum alloys, such as 2XXX series, 6XXX series and aluminum-lithium alloys, the strength can be significantly improved by solid solution and aging heat treatment. [0003] The poor forming ability of aluminum alloy at room temperature limits its forming method. The traditional warm forming process of aluminum alloy reduces the deformation resistance of the material and improves the deformation ability of aluminum alloy through heating. Although it e...
