Hydro forming process has a wide range of applications in automotive, aviation, aerospace and pipeline industries, mainly suitable for: along the axis of the component changes along the circular, rectangular or special-shaped section hollow structural parts, such as automobile exhaust system special-shaped pipe; Non-circular section hollow frame, such as engine bracket, instrument panel bracket, body frame (about 11%~15% of the vehicle mass); Hollow shaft and complex pipe fittings, etc. The suitable materials of hydro forming process include carbon steel, stainless steel, aluminum alloy, copper alloy and nickel alloy, etc. In principle, the materials suitable for cold forming are suitable for hydro forming process. Mainly for automobile parts factory, electronics factory, electric appliance factory, heat treatment plant, vehicle parts factory, gear factory, and air conditioning parts factory.
The equipment is especially suitable for bending, forming, flanging and other processes of central load parts with punching buffer device. And can also be used for punching and blanking processing, which is the first choice of shipping industry, pressure vessel industry, chemical industry and other industries.
It can be used for sheet metal parts of the stretch forming, turning, bending and stamping process, and can also be used for general pressing process according to the user’s needs to increase punching buffer, punching, mobile workbench and other devices. In addition to being used for forging and pressing, the three beam and four column hydraulic press can also be used for rectification, pressing, packing, pressing blocks and plates, etc.
It can also be used in the forming of axial parts, the profile of the calibration, withhold, installation process and sheet parts, stamping, bending, argue, stereotypes model, stretching, pressing of materials of plasticity, such as punching, bending,flanging thin stretch assignments, and may also perform calibration, pressure equipment, plastic products and powder products molding operation. It is also called universal hydraulic press because of its wide range of applications.
Compared with the traditional stamping process, hydro forming process has obvious technical and economic advantages in reducing weight, reducing the number of parts and molds, improving stiffness and strength, reducing production costs and so on. It has been applied more and more in the industrial field, especially in the automobile industry.
In the automotive industry, aviation, aerospace and other fields, reducing structural mass to save energy in operation is a long-term pursuit of people’s goal, is also one of the trends of the development of advanced manufacturing technology. Hydro forming is an advanced manufacturing technology for lightweight structure.
Hydro forming is also known as “internal high pressure forming”, its basic principle is to pipe as billet, in the pipe internal application of ultra-high pressure liquid at the same time, the two ends of the tube billet exert axial thrust, feeding. Under the joint action of two kinds of external forces, the tube material is plastic deformed, and finally fits with the inner wall of the mold cavity, and the shape and precision of the hollow parts meet the technical requirements.
