Abstract
A metal forming tool has a pair of jaws which are pivotally connected to one another. One of the jaws is provided with a channel which is part-circular in longitudinal direction of the channel and defines a part-circular arc in a plane passing through the channel normal to such direction. The other jaw carries a spherical or part-spherical element having a radius equal to that of the arc. When the jaws are closed, the spherical or part-spherical element makes line contact, or approximately line contact, with the channel in a plane perpendicular to the longitudinal direction of the channel.
Claims7
A forming tool, comprising a first member having a first forming element and a second member having a second forming element;
- said forming elements being movable towards and away from one another between an open position in which said forming elements are spaced from one another and a closed position in which said forming elements contact each other;
- and said second forming element being provided with a channel which extends in a predetermined direction and is bounded by a surface defining a hollow profile in a plane normal to said predetermined direction, said first forming element including a protrusion which faces said channel and is designed to make essentially line contact with said surface in said plane in said closed position.
A forming tool, comprising a first member having a first forming element and a second member having a second forming element;
- said forming elements being movable towards and away from one another between an open position in which said forming elements are spaced from one another and a closed position in which said forming elements contact each other;
- and said second forming element being provided with a channel which extends in a predetermined direction and defines a hollow part-circular arc in a plane normal to said predetermined direction, said first forming element being substantially spherical, facing said channel and having a radius substantially equal to that of said arc.
