The titanium alloy foil miniature piece ultrasonic vibration rubber forming device comprises a female mold, a male mold, a top plate and a blank holder, a first connecting hole is formed in the female mold, a connecting plate is arranged on the outer edge of the blank holder, the connecting plate is provided with a third connecting hole matched with the first connecting hole, the top plate is provided with a second connecting hole, and the connecting plate is provided with a fourth connecting hole matched with the second connecting hole; and the female mold is provided with a cavity for containing rubber, thetop plate is provided with a male mold connecting rod, the bottom of the male mold connecting rod is connected with the male mold, the blank holder is provided with a through hole matched with the male mold, and the male mold connecting rod is provided with an ultrasonic amplitude transformer. By means of the titanium alloy foil miniature piece ultrasonic vibration rubber forming device and the forming method, the forming quality of a foil plate can be improved, the foil plate forming resistance is small, the rebound is reduced, cracking is not prone to happening, and the forming quality is high.

Description

technical field [0001] The invention relates to the field of sheet metal forming and molds, in particular to an ultrasonic vibration rubber forming device and a forming method for a titanium alloy foil material miniature piece. Background technique [0002] With the rapid development of MEMS, micro medical devices, micro satellites, micro systems, etc., the demand for foil micro parts is increasing. Foil plate parts are more difficult than ordinary plates due to their sub-millimeter or micron size. The use of foil forming technology to process micro parts has the advantages of low cost, high efficiency and high quality, and has gradually developed into an indispensable technology for mass production of micro parts. Titanium alloy foil has been widely used in medical devices, aerospace and other fields due to its good biocompatibility and light weight. However, due to the high strength of titanium alloy, the formability of the foil is poor, the control of springback and wri...

Problems solved by technology

Although the invention integrates infrared heating, infrared temperature measurement, and air pressure forming technology into the micro-forming process, it can improve the forming performance of the metal foil plate, ensure the surface quality of the workpiece, and use high-pressure gas instead of the punch to simplify the process. Problems with wrinkling, cracking and springback
