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 such as a pipe, a bar, or a section iron comprising a hinge (1) provided with a bending head (2) which is alternatively a unidirectional, bidirectional, or double-headed one and with a loading arm (3) provided with clamping tools (3.sup.1)

2. A machine according to claim 1 characterized in that the hinge (1) is a vertical hinge provided with first means (4) for moving the hinge (1) about at least one pivot (11).

3. A machine according to claim 3 characterized in that the bending head (2) is provided with a motor (5) for driving the bending head (2) into rotation about an axis (A) orthogonal to the hinge (1).

4. A machine according to claim 4 characterized in that it comprises means (S) for synchronizing the first means (4) used to move the hinge (1) with the motor (5) used to drive the bending head (2) into rotation.

5. A machine according to claim 4 characterized in that the hinge (1) is provided with second means (6) for moving the bending head (2) vertically.

6. A machine according to claim 4 characterized in that the hinge (1) is provided with third means (7) for moving the bending head (2) horizontally.

7. A machine according to claim 7 characterized in that said second means (6) comprise at least one guide (6.sup.1).

8. A machine according to claim 8 characterized in that said second means (7) comprise at least one guide (7.sup.1).

Description

DESCRIPTION OF THE FIGURES

[0023] FIG. 1 is a three-dimensional representation of the machine according to the present invention in its idle status.

[0024] 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.

[0025] 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).

[0026] The hinge (1) is a vertical hinge provided with first means (4), 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 (4) used to move the hinge (1) with the motor (5) for driving the bending head (2) into rotation, synchronization means (S), not shown in the figures, are provided.

[0027] 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).

[0028] The hinge (1) is also provided with third means (7) for moving the bending head (2) in a horizontal direction, preferably complete with one or more guides (7.sup.1). The moving means (7) and the one or more guides (7.sup.1) are not shown in the figures.

[0029] 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 (S), which synchronize the first hinge (1) moving means (4), not shown in the figures, with the motor (5).
