Processing equipment for titanium alloy part with negative angle structure

The invention discloses processing equipment for a titanium alloy part with a negative angle structure. The equipment comprises a lower template, an upper template, a male die, a female die, a detaching ring, a limiting plate, an adapting nozzle and a ventilation pipe, wherein the upper template is connected to the upper side of the male die; a ventilation path is arranged in the male die; one end of the ventilation path is connected with the ventilation pipe through the adapting nozzle; the other end of the ventilation path communicates with the female die; the male die is connected with the female die; the detaching ring is positioned at a negative angle structure molded surface of the titanium alloy part with the negative angle structure in the female die; a blank holder is arranged at the lower end of the male die. According to the processing equipment for the titanium alloy part with the negative angle structure, the problem about forming sizes of parts with negative angle structures is solved, the research aims of high quality, high efficiency and low cost of check ring parts are achieved, and a practical novel technological equipment structure is provided for the processing of the check ring parts.
