Embodiment Construction
[0035] The present invention will be further described below in conjunction with the examples, but the protection scope of the present invention is not limited only to the examples.
[0036] Such as figure 1 As shown, a superplastic forming device includes a frame 2, a heating device 1, an upper mold 17, a lower mold 14, an air pressure pneumatic device 3, a hydraulic device 4, an operating device 5 and a heating control device 6. The pneumatic pneumatic device 3 provides the gas needed for superplastic forming, and controls the gas supply process and gas supply volume. The operating device 5 includes various sensors, which are used to collect data such as temperature and air pressure deformation rate during superplastic forming, analyze and compare them, output alarm information, and set parameters. The heating control device 6 is connected with the heating device 1 and controls the operation of the heating device 1 to control the heating process. The heating device 1 is ar...

The invention discloses a super-plastic forming device which comprises a machine frame, an upper mold, a lower mold, a heating device, a pneumatic air pressure device, a hydraulic device, an operating device and a heating control device; the heating control device comprises a lower slideway, an upper slideway and a plurality of heat preservation walls; the lower slideway, the upper slideway and the plurality of heat preservation walls form a closed cavity for material forming; the upper slideway, the lower slideway and heat insulation layers on the heat preservation walls can block heat conduction; heat-insulating reflective layers on the heat preservation walls can reflect thermal radiation; therefore, during super-plastic forming, the temperature is stable and is easy to control, the heat loss is less, and energy resources are saved; through the hydraulic device, the height of the upper slideway can be adjusted to meet the production demands of different sizes of products; guide rollers are arranged on the heat preservation walls, so that the heat preservation walls can be conveniently moved; different types of products can be produced through setting different parameters on the operating device. The super-plastic forming device has the benefits that the operation is convenient, the process adaptability is strong, and different production demands can be met.
Description
technical field [0001] The invention relates to the technical field of plate superplastic forming processing, in particular to a superplastic forming device. Background technique [0002] Superplasticity refers to the phenomenon that a material exhibits abnormally low rheological resistance and abnormally high rheological properties under certain internal and external conditions. It has the characteristics of large elongation, no necking, small stress and easy forming. Superplastic forming (SPF) refers to the method of forging and pressing using the superplasticity of some metals or some non-metals or some composite materials under specific conditions. At present, the main superplastic forming methods include: superplastic plate stamping (air pressure) forming, superplastic extrusion forming, superplastic die forging and superplastic diffusion bonding (DB), etc. Superplastic forming (SPF) technology is mainly used in the production of parts in the fields of aviation, aeros...
