Hydro-forming Press and Production Lin Hydro-forming process: The tube hydro-forming is a kind of manufacturing craft which infuses high pressure water into the tube, and make the tube wall into needed shape. Hydro-forming is widely used in automobile chassis, engine bracket, exhaust pipe, cam shaft, and axle and chassis parts, it is one of the effective methods for lightweight vehicle. Forming process route: Tube material cutting — Bending (CNC bending machine) — Pre-forming (Pre forming hydraulic press and mold) — Coated and lubrication —Hydro-forming — Laser cutting —Burrs shearing and grinding — Surface treatment. Hydro-forming press and equipment: Hydro-forming hydraulic press For closing the mold and pressure controlling, when closing the mold the pressure can be coordinated control by the inside of pressure in tube. Generally the press can be four columns and frame type, the bolster and slider meet the requirement of stress concentration, and have good rigidity Hydro-forming system Pressure intensifier and servo hydraulic system, the low pressure intensifier driven by hydraulic oil, uses proportional servo control, the high pressure intensifier emulsion (95% water), the pressure is 250-400Mpa. Adopts 1-2 sets pressure intensifier, when one mold with two cavities, adopt 2 sets of pressure intensifiers. Water (95% water + 5% emulsion) system: including quick flushing, pressure intensifier fluid infusion, pre flushing, emulsion filtration etc.
