摘要

THE use of hydroforming technology continues to grow even though initial investment for a hydroforming line is high and production rates are low, when compared with conventional stamping. Its growth continues because, for many applications, the benefits outweigh the drawbacks. Advantages include assembly simplification because several components can be consolidated into a single part; improved vehicle safety because hydroformed components often are stronger than components made with other methods; better fuel efficiency because hydroformed components often weigh less than other components; and better part quality because hydroforming offers accurate geometric dimensions and excellent consistency. To become a hydroformed component, a straight tubular blank with predetermined requirements such as diameter, wall thickness, and material composition is bent to desired angles so the tube resembles the finished component. The tube then is transferred to a preforming tool to deform it to a near-net-shaped component. The preformed tube then is hydroformed to the desired geometric shape using controlled internal pressure and axial feeding simultaneously.
