METHOD FOR QUICK GAS BULGING FORMING OF HOT METAL SHEET
20190060970 · 2019-02-28 ·

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. The method mainly includes the following steps: step one, placing a metal sheet blank to be formed on a forming mold; step two, 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; step three, heating the metal sheet blank to a preset forming temperature condition; step four, 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 step five, 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. The present invention is used for manufacturing a metal sheet part.

PRODUCT MOLDING METHOD AND APPARATUS AND PRODUCT
20190039111 · 2019-02-07 ·

The present invention relates to product molding method and apparatus and a product. A product molding apparatus comprises: a lower mold which has one or more molding grooves formed thereon and on which a material is mounted; an upper mold which is disposed above the lower mold and is for applying pressure to the material; and a punch part which is provided on the upper mold, is inserted into the molding grooves on the lower mold such that the material is molded, and discharges a filling material that has been pressed. The present invention enables quick and easy molding of a product by means of both hot press forming and hydroforming, thereby reducing manufacturing procedures and time and thus saving cost.

USE OF A SUPERSONIC FLUIDIC OSCILLATOR IN SUPERPLASTIC FORMING AND SYSTEM FOR SAME
20190001389 · 2019-01-03 ·

A method of forming a material using a supersonic fluidic oscillator in a superplastic forming process and a related system is provided. The method comprises applying pressurized gas at a baseline pressure to a surface of the material when the material is received within a cavity of a forming tool, and creating pressure fluctuations with a supersonic fluidic oscillator relative to the baseline pressure within the tool cavity. Each pressure fluctuation (i) deforms the material and (ii) subsequently allowing for a partial stress relief of the material during the forming process.

High speed blow forming processes

A method of forming a part includes: inserting a blank into a die, the die comprising a mold mounted above a sealing counterpart; clamping the blank between the mold and the sealing counterpart; applying first pressure on the blank from the sealing counterpart so the blank is pressed upward to form a shaped part corresponding to the mold; applying a vacuum to the shaped part to hold it against the mold also after separating the mold and the sealing counterpart, the vacuum applied through at least one opening in the mold located in a corner of the mold that the blank does not reach when the first pressure is applied; and discontinuing the vacuum to allow the shaped part to be released from the mold.
