Forming method of high-temperature alloy honeycomb sandwich structure

The invention provides a high-temperature alloy honeycomb sandwich structure forming method which comprises the following steps: S1, forming a high-temperature alloy honeycomb core: connecting multiple layers of high-temperature alloy corrugated boards made of high-temperature alloy foils to form the high-temperature alloy honeycomb core; s2, the high-temperature alloy skin/framework is subjected to electric pulse bending forming, and the high-temperature alloy skin and the high-temperature alloy framework are subjected to pressing forming through a multi-point digital mold; and S3, the high-temperature alloy honeycomb sandwich structure is subjected to self-resistance heating diffusion brazing, and the high-temperature alloy framework, the high-temperature alloy honeycomb core and the high-temperature alloy skin are subjected to diffusion brazing to form the high-temperature alloy honeycomb sandwich structure. According to the method, electric pulse rapid heating and multi-point die digital flexible shape ad
