Abstract

1481339 Bending MANNESMANN AG 16 Oct 1974 [17 Oct 1973] 44878/74 Headings B3P and B3E A pair of tool sets 1, 1<SP>1</SP> for bending the edges of a metal plate 30 which is to be formed into a tube each comprise a convex upper tool 2, 2<SP>1</SP> relatively movable to a concave lower tool 3, 3<SP>1</SP>, the configuration of both tools of each set being one and the same segment of an involute of a circle. In one embodiment, a lower die 3, 3<SP>1</SP>, of each set is horizontally displaceable by devices 7, 8 in a tool carrier 4, 4<SP>1</SP> which is connected to a hydraulic cylinder 6 in a movable frame 5, 51. An upper die 2, 21 of each set is pivotable by a device 12 about a horizontal axis 11. The radius of the bending surface of each die increases from one end of the die to the other so that when the dies are set by the devices 7, 8, 12 relative to each other for a particular plate thickness, a constant gap is formed between the dies of each set. The bending radius produced at the plate edges is thereby dependent on the amount of insertion of the plate into the die gaps (Figs. 5-7, not shown). In another embodiment, the tools are formed by rolls (Fig. 8, not shown).
