Description

Technical Field

[0001] The utility model belongs to the technical field of sheet metal progressive forming processing and relates to movable temperature-controlled progressive forming equipment. Background Art

[0002] Difficult-to-form materials (such as titanium alloys, magnesium alloys, etc.) have low forming limits at room temperature, are easy to crack, have large springbacks and require large forming forces, making incremental forming difficult. Therefore, when forming such materials, heating-assisted forming is often used to reduce the material strength by increasing the forming temperature, thereby improving the material's forming performance and reducing the forming force. Commonly used heating methods are divided into overall heating and local heating according to the different heating areas. Overall heating requires a lot of energy, which will increase costs; heating the entire workpiece takes a certain amount of time, which will increase the production cycle; if the heating is uneven or the temperature is not properly controlled, thermal stress concentration may occur, thereby affecting the material's performance and shape accuracy. The existing local heating methods currently available will result in uneven heating of the formed parts, with local temperatures being too high or too low; the heating area is small and heating is hindered when the plate is bent or in a complex shape; and fine operation and control are required.
