A superplastic forming machine was developed,and the design of the superplastic forming ma-chine was determined and described in detail. The main frame of the equipment adopts the hydraulic pre-tensioned combination tie rod frame type structure with 6 piston cylinders and 4 guide rods structure,which ensures the uniformity of pressurisation and guiding precision. The hydraulic system adopts servo motor-driv-en oil pump form,which reduces energy consumption,and the pneumatic pressure control precision ensures the accuracy of superplastic forming/diffusion connection parts. The equipment has the features of compact structure,strong durability and high workpiece yield.
