摘要： For forming a tubular work into a shaped hollow product by using hydroforming process, a method and a device are described. In the method, female and male dies are prepared. The female die has a longitudinally extending cavity which has a polygonal cross section when receiving the male die. The tubular work is placed into the cavity of the female die. The interior of the tubular work is then fed with a hydraulic fluid, and the pressure of the fluid is increased to a given level. The given level is smaller than a critical level that causes a bulging of the tubular work. The male die is then pressed against the tubular work to deform the same while keeping the hydraulic fluid at the given level, thereby forming a shaped hollow product that has a polygonal cross section that conforms to that of the cavity. The pressing work is continued until a circumferential length of the shaped hollow product becomes shorter than that of the tubular work.
摘要翻译：为了通过使用液压成型工艺将管状工件形成成型的中空产品，描述了一种方法和装置。在该方法中，制备阴模和阴模。阴模具有纵向延伸的空腔，当接收阳模时，其具有多边形横截面。将管状工件放入阴模的空腔中。然后，管状工件的内部被供给液压流体，并且流体的压力增加到给定的水平。给定的水平小于导致管状工作膨胀的临界水平。然后将阳模压在管状工件上以使其变形，同时将液压流体保持在给定的水平，从而形成具有与腔的多边形横截面一致的成形中空产品。压制工作继续进行，直到成形中空制品的圆周长度变得短于管状工件的圆周长度。
