    • A stretch roll forming apparatus (10) has multiple roll forming stations (12, 14, 16, 18, 20, 40, 22) arranged serially so that a sheet metal workpiece (24) can be advanced through the stations in sequence. Each station includes a pair of roller dies supported by an inboard support station (30, 40) and by an outboard support station (32, 42), in spaced apart relationship, so that the roller dies are each rotatable about a horizontal axis. The roller dies are configured to shape a sheet metal workpiece which is advanced between them. At least one of the roll forming work stations is a stretch roll forming work station (40). In this station, the roller dies (44, 46) each have a frusto-concial shape. The roller dies are positioned such that the taper of one extends from the inboard support to the outboard support while the taper of the other extends from the outboard support to the inboard support. When a sheet metal workpiece (24) is advanced between the roller dies (44, 46) of the stretch roll forming station (40), one longitudinal edge of the workpiece is stretched relative to the other longitudinal edge. This gives the workpiece a longitudinal curvature.
    • 拉伸辊成形设备(10)具有多个顺序布置的轧制成形工位(12,14,16,18,20,40,22),使得金属板工件(24)可以依次前进通过工位。 每个工位包括一对辊模,其由内侧支撑台(30,40)和外侧支撑台(32,42)以间隔开的关系支撑,使得辊模可以围绕水平轴线旋转。 辊模被配置成使在它们之间前进的金属板工件成形。 至少一个辊轧成形工位是拉伸成形工位(40)。 在该工位中,辊模(44,46)各自具有截头圆锥形状。 滚子模具被定位成使得一个锥形从内侧支撑件延伸到外侧支撑件,而另一个的锥形从外侧支撑件延伸到内侧支撑件。 当钣金工件(24)在拉伸辊形成站(40)的辊模(44,46)之间前进时,工件的一个纵向边缘相对于另一个纵向边缘被拉伸。 这给予工件纵向曲率。

    • 拉伸辊形成设备(10)具有多个串联布置的辊子形成站(12,14,16,18,20,40,22),使得金属板工件(24)能够依次前进通过站。 每个站包括一对由内侧支撑站(30,40)和外侧支撑站(32,42)以间隔开的关系支撑的滚筒模具,使得滚筒模具各自可围绕水平轴线旋转。 滚筒模具被构造成成形在它们之间前进的金属片工件。 至少一个辊轧成形工位是拉伸辊成形工位(40)。 在该工位中,辊模(44,46)各自具有截头圆锥形状。 辊模定位成使得其中的一个从内侧支撑件延伸到外侧支撑件,而另一个的锥形件从外侧支撑件延伸到内侧支撑件。 当钣金工件(24)在拉伸辊形成站(40)的辊模(44,46)之间前进时,工件的一个纵向边缘相对于另一个纵向边缘被拉伸。 这给工件一个纵向曲率。
