在欧洲,管材、型材以及板材的液压成形是密切相关的.液压成形产品主要是用于汽车工业批量生产的零件以及一些有独特用途的零件,其市场仍然在逐渐增长.目前轻量化制造、新型零件的高度功能集成化以及关于使用内高压件的不断积累的设计经验、理念,正影响着液压成形新技术的开发.由于可观的利润率,开放截面和闭合截面的铝合金型材的液压成形件正在试制,并在此背景下,开展了一些专用车面板的液压成形技术开发.这个利润率,将从半成品零件、成形中间过程,直到最终总成件整个工艺链来计算.从管材和板材的液压成形件来看,提高液压成形模具的功能集成性也是必须要做的工作.文章作者就内高压成形的模具设计以及功能集成给出了解决方案,并进一步讨论了内高压成形工艺的利润率.

Meanwhile the interest in Europe in hydroformed tubes, extrusions and sheet metals has become relative. The market for hydroformed products is still slightly growing, but mainly for work pieces from quantity production for the automotive industry as well as for highly individual niche products. Today light weight production, higher functional integration of new work pieces and increasing design experience regarding utilisation of hydroformed single parts are influencing the development of new hydroforming technologies. Hydroformed open and closed cross sectional aluminium extrusions are on trial now regarding their specific profitability. Moreover hydroforming of car panels for niche vehicles is increasingly discussed on this background. The profitability thereby has to be considered along with the entire process chain of semi-finished parts, the forming process itself until the finished joined parts. There is need for action in order to increase the functional integration of hydroforming tools regarding the semi-finished tubes respectively semi-finished sheet metal blanks. This paper presents solutions for tool design and functional integration for hydroforming tubes. Furthermore the profitability of IHP processes is demonstrated.
