Abstract

The invention discloses a preparation method and a processing die for an aluminum alloy special-shaped sheet metal part for rail transit, wherein the method comprises: obtaining the structural characteristics and dimensions of the special-shaped sheet metal part, and determining a mold for the special-shaped sheet metal part Structural parameters of the two processed parts; according to the above structural parameters, the selected plate is determined, wherein the thickness of the plate is 0-0.5mm larger than the thickness of the special-shaped sheet metal part; superplastic forming processing is performed on the plate to obtain a mold of the special-shaped sheet metal part Two workpieces; then place one mold and two workpieces on the anti-deformation tooling, and place an anti-deformation pressure block at a predetermined position. After the one mold and two workpieces are cooled to room temperature, they are mechanically cut to obtain the preparation. Good profiled sheet metal. The invention solves the technical problems in the related art that the machining control of the shape precision of the aluminum alloy special-shaped sheet metal parts is difficult, resulting in poor surface quality and serious wall thickness reduction.

Description

technical field [0001] The invention belongs to the field of precision sheet metal processing, and relates to a preparation method and a processing die of an aluminum alloy special-shaped sheet metal part used for rail transit. Background technique [0002] Aluminum alloys are widely used in aerospace, rail transit, weaponry and other fields because of their excellent performance. In the field of rail transit, the integration and lightweight of aluminum alloy special-shaped sheet metal parts are getting higher and higher, and the manufacturing precision requirements are becoming more and more stringent. In the field of sheet metal forming, the commonly used manufacturing methods of aluminum alloy special-shaped sheet metal parts mainly include cold stamping and hot stamping. In the related art, due to the low elongation rate of aluminum alloy at room temperature, it is easy to produce large springback, so the aluminum alloy special-shaped sheet metal parts prepared by cold ...
