Problems solved by technology

[0007] Given the length of the pipe to be bent (which measures approximately 4m to 30m), each of these ancillary equipment needs to occupy a large area (greater than 1000m 2 ) and requires substantial cost (equipment plus infrastructure)
Moreover, this technical solution leads to a doubling of operating costs (production, maintenance, etc.

Embodiment Construction

[0047] The bending machine according to the invention, which is shown by way of example in the accompanying drawings, comprises a bending machine for the manufacture of U-shaped tubes, which tubes are particularly suitable for the manufacture of heat exchangers, for example nuclear exchangers.

[0048] It should be noted that throughout the following detailed description, the bending machine is described in its conventional position of use, in particular that the bending axis (z) is a vertical axis and the axis of movement (x) of the workpiece part is a horizontal axis. Accordingly, the terms "vertical, horizontal" etc. refer to such positions.

[0049] The bending machine according to the present invention firstly comprises a frame 1, on the horizontal upper surface of which is provided a fixed side plate 2, on which a first set of gears 3 is positioned, said first set of gears along the The axis of motion (x) of the bent workpiece T is arranged parallel to the axis, said gea...

Abstract

A bending machine for the manufacture of bent workpiece parts, in particular tubes for heat exchangers, comprising a frame (1) on which is mounted an articulated arm (19) comprising a rotationally fixed arm and A swivel arm, the specific energy of which grips nicotine, extends along the transverse axis of motion (y) and is supported by the swivel shaft (4) and has means for attaching the clamping jaws (M) and also includes a free means of rotating rollers (1) or clamping structures fixed rotatably around said axis of rotation on the axis of rotation (40) of the articulated ratio (19), driving the rollers (G1-G5, G'1 - G'5) Divided into two groups positioned on either side of the longitudinal axis (x) and comprising means for synchronously rotating the drive rollers for actuating said drive rollers.

Description

technical field [0001] The invention relates to a bending machine for the manufacture of profile sections, in particular for exchanger tubes, comprising a frame mounted for movement along a longitudinal axis (x ) means for holding a workpiece portion, and means for bending said workpiece portion. Background technique [0002] The manufacture of heat exchangers, in particular industrial heat exchangers and especially in the energy sector and especially in the nuclear industry, requires the manufacture of a large number of roughly U-shaped tubes with a bend radius (bendradii) Covering a large range of values, the range typically includes 50mm to 2500mm. A conventional nuclear exchanger thus comprises 300 to 500 tubes, with about 50 different bending radii. [0003] Currently, given this range of bend radii and in order to meet the precise and final processing quality requirements specific to the nuclear industry, the bending of the tube requires the application of two differ...
