Abstract
A multi-function pipe bending machine (1) comprising a base structure (2), a first slide (8) slidably engaged to the base structure (2) along a first traverse direction, a second slide (11) slidably engaged to the first slide (8) along a second traverse direction perpendicular to the first direction, a first and a second bending die (14a, 14b), at least one unit (15a, 15b) for positioning and locking a pipe (6) to be bent, and a bending arm (18) active on the pipe (6) against the action of the bending dies (14a, 14b).
Claims4
A multi-function pipe bending machine comprising:
- a base structure,
- a first support body slidably engaged to said base structure along a first horizontal axis transverse to a longitudinal axis of a pipe to be bent,
- first actuation means for displacing said first support body,
- a second support body slidably engaged to said first body along a second vertical axis transverse to said longitudinal axis of said pipe to be bent perpendicular to said first horizontal axis,
- second actuation means for displacing said second support body,
- a carriage for supporting a pipe to be bent, said carriage being disposed in a cantilevered position with respect to the base structure and being horizontally movable along one side of the base structure,
- an upper and a lower bending die spaced apart from each other in superposed relationship, each of said bending dies comprising a plurality of die members coaxially engaged to said second support,
- a first and a second unit engaged to said second support body for positioning and locking the pipe to be bent respectively against said first and said second bending die,
- a bending arm rotatably engaged to said second support coaxially to said bending dies and active on said pipe against the action of one of said upper and lower bending dies.
