Machine for bending a thread-like material such as a pipe by way of a system for simultaneously loading a pipe to be bent and unloading a bent pipe

Abstract

A machine for bending a thread-like material such as a pipe, a section iron, a bar, or the like, briefly a pipe, provided with a system for simultaneously loading a pipe to be bent and unloading another, already bent pipe, comprising a vertical hinge provided with a bending head provided with a motor for driving the bending head into rotation about an axis orthogonal to the hinge.

Claims

1. A machine for bending a thread-like material comprising: a hinge provided with a bending head, wherein said hinge is rotatable about at least one pivot, and a loading arm provided with clamping tools, wherein said clamping tools include a pair of closable clamping claws for picking-up the thread-like material, and wherein said loading arm is fixed with respect to said hinge for movement about said at least one pivot, and wherein the bending head is provided with a motor for driving the bending head.

2. The machine according to claim 1, wherein the hinge is a vertical hinge that moves about said at least one pivot.

3. The machine according to claim 1, wherein said motor drives the bending head into rotation about an axis (A) orthogonal to the hinge.

4. The machine according to claim 3, wherein said machine comprises means (S) for synchronizing the movement of the hinge with the motor used to drive the bending head into rotation.

5. The machine according to claim 4, wherein the hinge is provided with a means for moving the bending head vertically.

6. The machine according to claim 4, wherein the hinge moves the bending head horizontally.

7. The machine according to claim 5, wherein said means for moving the head vertically comprises at least one elongated guide.

8. The machine according to claim 7, wherein at least one elongated guide is provided for moving the head vertically.

9. The machine according to claim 1, wherein the thread-like material comprises a pipe.

10. The machine according to claim 1, wherein: said at least one pivot defines a first axis extending vertically; and said bending head rotates about a second axis, wherein said second axis is orthogonal to said first axis.

11. The machine according to claim 2, wherein said bending head is joined to said hinge such that when said hinge moves about said at least one pivot, said bending head also correspondingly moves about said at least one pivot.

Description

DESCRIPTION OF THE FIGURES

(1) FIG. 1 is a three-dimensional representation of the machine according to the present invention in its idle status.

(2) FIG. 2 shows a graphical three-dimensional representation of the machine according to the present invention while a pipe to be bent is loaded and simultaneously another, already bent pipe is unloaded.

(3) FIG. 1 shows a machine for bending a thread-like material such as a pipe, a bar, or section iron according to the present invention, which comprises a hinge (1). Said hinge (1) is provided with a bending head (2). Such bending head can be a unidirectional, bidirectional, or double-headed one, alternatively. In the case of FIG. 1, the type of the bending head is not shown. The hinge (1) is provided with a loading arm (3) complete with clamping tools (3.sup.1).

(4) The hinge (1) is a vertical hinge provided with first means, not shown in the figures, for moving the hinge (1) about at least one pivot (1.sup.1). FIG. 1 also shows the bending head (2) provided with a motor (5) for driving the bending head (2) into rotation about an axis (A) orthogonal to the hinge (1). In order to synchronize the first means used to move the hinge (1) with the motor (5) for driving the bending head (2) into rotation, a synchronization means, not shown in the figures, is provided.

(5) The hinge (1) is provided with second means (6) for moving the bending head (2) in a vertical direction and FIG. 1 shows two guides (6.sup.1) which are a preferred embodiment of the moving means (6).

(6) The hinge (1) is also provided with third means for moving the bending head (2) in a horizontal direction, preferably complete with one or more guides. The moving means and the one or more guides are not shown in the figures.

(7) FIG. 2 shows the hinge (1) rotated about the pivot (1.sup.1) for making it possible for the clamping means (3.sup.1) of the loading arm (3) to load a pipe to be bent and the bending head (2) driven into rotation about the axis A by the motor (5) to unload another, already bent pipe. Such loading and unloading operations take place simultaneously thanks to the synchronization means, which synchronize the first hinge (1) moving means not shown in the figures, with the motor (5).
