Abstract
A machine for bending pipes (2; 63; 78) sections or similar of a given section (S1; S2; S3) has a guide device (6) having a longitudinal axis (9) for guiding the pipes (2; 63; 78) in a feed direction (D1) parallel to the axis (9); and a bending member (7) movable with respect to the guide device (6) in a plane (P1) perpendicular to the feed direction (D1), and having an annular guide (50), which has a passage section (45; 61; 76) for the pipes (2; 63; 78) substantially equal to the section (S1; S2; S3) of the pipes (2; 63; 78) and is defined by rollers (40; 52; 82; 67) rotating about respective axes (41; 53; 83; 68) lying in a plane coplanar with the passage section (45; 61; 76).
Claims13
A machine for bending pipes (2;
- 63;
- 78) and sections having a given cross section (S1;
- S2;
- S3), the machine comprising:
- a guide device (6) for guiding said pipes (2;
- 63;
- 78), said guide device (6) having a longitudinal axis (9) for guiding said pipes (2;
- 63;
- 78) in a feed direction (D1) parallel to the axis (9);
- and a bending member (7) movable with respect to said guide device (6) in a plane (P1) perpendicular to said feed direction (D1), said bending member (7) comprising an annular guide (50) defining a passage section (45;
- 61;
- 76) for said pipes (2;
- 63;
- 78) substantially equal to the section (S1;
- S2;
- S3) of said pipes (2;
- 63;
- 78);
- said annular guide (50) being defined by rollers (40;
- 52;
- 82;
- 67);
- said rollers (40;
- 52;
- 82;
- 67) rotating about respective axes (41;
- 53;
- 68) coplanar with one another and with said passage section (45;
- 61;
- 76);
- each of said rollers (40;
- 52;
- 82;
- 67) having a surface of revolution (44;
- 57;
- 85;
- 72) generated by rotation of a respective generating line (47;
- 58;
- 86;
- 73);
- said generating lines (47;
- 58;
- 86;
- 73) collectively defining a perimeter portion of said passage section (45;
- 61;
- 76);
- each of said rollers (40;
- 52;
- 82;
- 67) comprising two connecting surfaces (88a, 88b) on opposite sides of the surface of the revolution (44;
- 57;
- 85;
- 72);
- each connecting surface (88a;
- 88b) contacting the connecting surface (88b;
- 88a) of an adjacent roller (40;
- 52;
- 82;
- 67) to prevent a displacement of each roller (40;
- 52;
- 82;
- 67) with respect to the adjacent rollers (40;
- 52;
- 82;
- 67).
A machine for bending pipes (2;

- 63;
- 78) in a feed direction (D1) parallel to the axis (9);
- and a bending member (7) movable with respect to said guide device (6) in a plane (P1) perpendicular to said feed direction (D1), said bending member (7) comprising an annular guide (50) defining a passage section (45;
- 61;
- 76) for said pipes (2;
- 63;
- 78) substantially equal to the section (S1;
- S2;
- S3) of said pipes (2;
- 63;
- 78);
- said annular guide (50) being defined by rollers (40;
- 52;
- 82;
- 67);
- said rollers (40;

- 61;
- 76);
- each of said rollers (40;
- 52;
- 82;
- 67) having a surface of revolution (44;
- 57;
- 85;
- 72) generated by rotation of a respective generating line (47;
- 58;
- 86;
- 73);
- said generating lines (47;
- 58;
- 86;
- 73) collectively defining a perimeter portion of said passage section (45;
- 61;
- 76);
- each of said rollers (40;
- 52;
- 82;
- 67) comprising two connecting surfaces (88a, 88b) on opposite sides of the surface of the revolution (44;
- 57;
- 85;
- 72);
- each connecting surface (88a;
- 88b) contacting the connecting surface (88b;
- 88a) of an adjacent roller (40;
