Embodiment Construction

[0032] As shown in the accompanying drawings, according to the coiling / uncoiling machine of the present invention, generally marked 1, it is usually located between the rolling mill (not shown in the figure) and the downstream traction assembly for subsequent processing, and the coiling / uncoiling machine includes A cross-shaped structure 2 and a table corresponding to each arm of the cross-shaped structure.

[0033] These workbenches include:

[0034] - a coiling station 3 for forming coiled tubing;

[0035] - Taper station 4 for tapering one end of the tube;

[0036] - an uncoiling station 5 for uncoiling the conical tube coil;

[0037] - Wait for station 6.

[0038] On each arm of the cross-shaped structure 2 there is a coil support roller 7, under which bending means 8 are integrally fixed.

[0039] The cross-shaped structure 2 can be rotated 90 degrees about its X-axis direction, so that the drum 7 and the bending device 8 can be moved from one station to the other dur...

Abstract

Tube coiling / decoiling machine, used in particular downstream of a rolling mill, capable of significantly increasing the production rate by automating numerous operations, consequently reducing labour costs. In particular said coiling / decoiling machine comprises a drum (7), suitable for rotating around its longitudinal axis, provided with a cavity (9) for containing the first end of the tube (13) corresponding to a peripheral portion there of. A relative tube coiling / decoiling process more efficient than the one currently used is described.

Description

technical field [0001] The invention relates to a coiling / uncoiling machine for metal pipes and a corresponding method, which can be specifically applied downstream of rolling mills. Background technique [0002] Downstream of a pipe mill that rolls, for example, copper pipe, there is usually a coiler / uncoiler for coiling straight pipe from the mill into coils and supporting the formed coils, which are then uncoiled for downstream drawing. stretch processing. [0003] When the rolled tube has a length greater than 100 meters, it is coiled into a coil weighing at least 500 kg, thus reducing the overall size. The tube material is easily deformed due to the annealing process used in the upstream rolling process. [0004] The coiler / uncoiler has a cross-type structure with two or four coil support tables, each of which is equipped with two motorized rollers with grooves, whose shafts are set horizontally to support the weight of the entire coil . [0005] Between the rolling...
