Abstract
A machine for bending sections (2) having a longitudinal axis (3) and a constant cross section along the longitudinal axis (3) feeds the sections (2) longitudinally in a first direction (D1), and has a first and a second annular die (11, 12); an ass (15) connected to the second annular die (12) and movable in a plane perpendicular to the first direction (D1) to move the second annular die (12) into a number of operating positions with respect to the first annular die (11) to bend the sections (2); and a joint (22; 39) connecting the first and the second annular die (11, 12), and which forces the second annular die (12) to assume a given position with respect to the first annular die (11) for each position assumed by the assembly (15).
Claims12
A machine for bending sections (2) having a longitudinal axis (3) and a constant cross section along the longitudinal axis (3);
- the machine feeding the sections (2) longitudinally in a first direction (D1), and comprising:
- a first and a second annular die (11, 12), and an assembly (15) connected to the second annular die (12) and movable in a plane perpendicular to the first direction (D1) to move the second annular die (12) into a number of operating positions with respect to the first annular die (11) to bend the sections (2);
- and the machine being characterized by comprising a joint (22;
- 39) connecting the first and the second annular die (11, 12), and which forces the second annular die (12) to assume a given position with respect to the first annular die (11) for each position assumed by said assembly (15);
- and the machine being characterized by comprising a guide device (5) for guiding said sections (2) along a first axis (10) parallel to said first direction (Dl);
- said joint (22;
- 39) imposing that said second annular die (12) only rotate with respect to the first annular die (11) about a point (P) located along said axis (10).
A machine for bending sections (2) having a longitudinal axis (3) and a constant cross section along the longitudinal axis (3);
- the machine feeding the sections (2) longitudinally in a first direction (D1), and comprising:
- a first and a second annular die (11, 12), and an assembly (15) connected to the second annular die (12) and movable in a plane perpendicular to the first direction (D1) to move the second annular die (12) into a number of operating positions with respect to the first annular die (11) to bend the sections (2);
- and the machine being characterized by comprising a joint (22;
- 39) connecting the first and the second annular die (11, 12), and which forces the second annular die (12) to assume a given position with respect to the first annular die (11) for each position assumed by said assembly (15);
- and the machine being characterized by comprising a guide device (5) for guiding said sections (2) along a first axis (10) parallel to said first direction (D1);
- said joint (22;
- 39) imposing that said second annular die (12) only rotate with respect to the first annular die (11) about a point (P) located along said axis (10), said point (P) being located between said first and second annular die (11, 12);
- said first and said second annular die (11, 12) respectively defining a first and a second passage (13, 14);
- said point (P) being equidistant from the first and second passage (13, 14);
- said joint (22, 39) comprising a universal joint (23, 39) defining a second and a third acis (30, 31;
- 43, 45);
- at least the second axis (30;
- 43) intersecting said first axis (10) at said point (P);
- said joint (22) comprising a mechanism (24) having first levers (25), second levers (26) and rods (27) for positioning said second annular die (12).
A machine for bending sections (2) having a longitudinal axis (3) and a constant cross section along the longitudinal axis (3);
- the machine feeding the sections (2) longitudinally in a first direction (D1), and comprising:
- a first and a second annular die (11, 12), and an assembly (15) connected to the second annular die (12) and movable in a plane perpendicular to the first direction (D1) to move the second annular die (12) into a number of operating positions with respect to the first annular die (11) to bend the sections (2);
- and the machine being characterized by comprising a joint (22;
- 39) connecting the first and the second annular die (11, 12), and which forces the second annular die (12) to assume a given position with respect to the first annular die (11) for each position assumed by said assembly (15);
- the machine being characterized by comprising a frame (4);
- said first annular die (11) being integral with said frame (4);
- and said assembly (15) being positionable selectively with respect to said frame (4) in a horizontal second direction (D2) perpendicular to the first direction (D1), and in a third direction (D3) perpendicular to the first and second direction (D1, D2);
- said assembly (15) comprising guides (16) parallel to said first direction (D1);
