Abstract
A method for forming a gourd petal component is provided. The method includes obtaining a sheet material with M installation ends. Second wires are divided into M groups based on a cross-sectional area of each installation end. The sheet material is installed on a flexible mold. First wires and the second wires are connected to the sheet material and a current cabinet respectively. A power supply is turned on, electric pulses are applied to M areas including different installation ends for heating. When a temperature of the sheet material reaches a creep aging temperature, a load is applied on a top of the flexible mold to adsorb the sheet material. A creep aging forming is maintained for a preset time under the load and a high temperature. Once the load and the external current are unloaded, the gourd petal component is obtained after a cooling.
