  • Patent number: 10710139
    Abstract: A method for quick forming of a metal sheet. In an embodiment, the method includes the following steps: placing a metal sheet blank to be formed on a forming mold; introducing high-pressure gases with equal pressures simultaneously into upper and lower enclosed cavities respectively formed by the metal sheet blank and the sealing mold, and the metal sheet blank and the forming mold; heating the metal sheet blank to a preset forming temperature condition; quickly releasing the high-pressure gas from the cavity formed by the metal sheet blank and the forming mold, such that the metal sheet blank bulges; and discharging the gas from the cavity formed by the metal sheet blank and the sealing mold, and opening the mold to obtain a formed metal sheet part.

  • Patent number: 10589504
    Abstract: A lamination manufacturing method for large-sized metal components with complicated structures is provided, relating to a part manufacturing method to solve the problem that traditional machining, entire plastic forming and the existing additive manufacturing method are difficult to manufacture large-sized metal components with complicated special-shape structure and high-performance requirement. The manufacturing method includes the steps: step 1. obtaining a three-dimensional digital model of a large-sized metal component with complicated structure, and dividing the model into a plurality of slice layers; step 2. selecting the actually available metal sheet corresponding to the thickness of each slice layer divided in step 1, and machining each metal sheet to obtain a shaped sheet consistent with the model of each slice layer in step 1; step 3. stacking the shaped sheets obtained through machining of step 2 according to the order of the corresponding slice layers in step 1; and step 4.

  • Patent number: 10576524
    Abstract: The present invention provides a die capable of achieving rapid forming and quenching therein. The die includes an upper die, a blank holder and a lower die, where the upper die is composed of an internal solid die core and a thin-walled skin. Grooves in communication with each other are disposed between the internal solid die core and the thin-walled skin. In a forming stage, the grooves are not filled or filled with a heat insulating material such as a gas; and in a quenching stage, a low-temperature medium is introduced into the grooves. The die can be used to achieve rapid forming and quenching of metal materials of different types and thicknesses.

  • Publication number: 20190366409
    Abstract: Provided is a method for quick forming of a hot metal sheet. The method relates to a technology for forming a metal sheet part, and solves the problem that the existing hot metal sheet forming technology cannot ensure that a blank is deformed under reasonable temperature and pressure conditions, thereby failing to realize precise and quick forming of a complex metal sheet part, especially a thin-walled part.
