Abstract

The invention discloses a plate warm electro-hydraulic high-speed impact-quasi static hydraulic composite forming device and a plate forming method achieved by adopting the device and relates to the field of metal material processing forming to solve the problems that forming of plates and complex parts is difficult, film attaching is poor, and deformation is not even. A vacuum pump is used for pumping out gas in a female die cavity; a fluid injection device is adopted for injecting high-temperature-resisting liquid to a liquid chamber; a heating device is used for heating the female die cavity, the high-temperature-resisting liquid in the liquid chamber is heated, preheating on a to-be-processed plate is completed, and heat preservation is conducted on the to-be-processed plate; an electromagnetic forming system is used for conducting discharging forming on the to-be-processed plate; high-pressure warm liquid is slowly injected into the liquid chamber under the quasi static condition, and quasi static hydraulic forming is conducted on the to-be-processed plate; and the high-pressure warm liquid in the liquid chamber is cooled to the room temperature within a period of time, waste liquid is recycled, an electro-hydraulic forming die is opened, and the to-be-processed plate is taken away. The device and the method are used for forming plates.

Description

technical field [0001] The invention relates to a plate warming, electro-hydraulic high-speed impact-quasi-static hydraulic composite forming device and a plate forming method realized by the device. It belongs to the field of metal material processing and forming. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, sheet metal forming parts are more and more widely used in people's lives. The forming of the plate usually adopts the stamping method. The traditional stamping method requires the design of a special mold. Not only the mold structure is complex, the design cycle is long, and the manufacturing cost is high. More importantly, the punch and the die need to be precisely matched and positioned. , Also consider the wear and fit tolerance of the male and female dies, as well as the hardening of the material during the stamping forming process, which will cause an increase in deformation resista...
