- Device 1 essentially consists of a base frame 2 on which a support member 3 for a pipe T to be cleaned and at least one cleaning head 4 are mounted.
- the support member 3 and cleaning head 4 are movable with respect to each other and they move close to and away from each other along a first direction X which is coincident with the longitudinal axis Y of pipe T held by the support member 3 itself.

- first 14a and second 14b shoes are mutually spaced apart from each other to enable removal of an already cleaned pipe T or setting of a pipe T to be cleaned.
- the active surfaces 15a, 15b each have a hemi-cylindrical concave shape and, once they are close to each other, form an overall active surface 15 the shape of which matches that of the pipe T to be clamped.

- jaws 18a, 18b too can be dismantled from the support structure 17 and replaced with other jaws 18a, 18b having active surfaces 19a, 19b of different sizes, in this context "sizes" meaning the bending radii of same - or even different shapes, to clean pipes T of non circular section.

Abstract
Description
- The present invention relates to a pipe-cleaning device. In particular, the present invention relates to a device for external cleaning of pipes that are subsequently to be submitted to bending operations.
- It is known that bent metal pipes are used in many application fields. For example, in the motor-vehicle industry bent pipes are employed for making hydraulic and pneumatic circuits, in the braking system, air-conditioning system or cooling system for engines. Bent pipes are also utilized for accomplishing the exhaust system in motor-vehicles.
- Pipes are for example obtained by drawing and, in order to avoid dangerous inconveniences in the subsequent bending process, cleaning of same at their outer surface is required. In fact, as known, pipes are held during bending by a head provided with a bending die and a presser element active on the pipe against the die action. The die is pivotally movable relative to the presser element and rotation of same gives rise to pipe bending. The requirement of externally cleaning the pipes mainly arises from the fact that possible metal scraps such as burrs or dust remaining on the pipe after drawing can penetrate into the soft material of which both the die and presser element are made and consequently cause scratching of all pipes that are subsequently bent by the die itself.
- Devices for internal and external cleaning of pipes are known that consist of tanks usually holding suitably treated waters into which the pipes are introduced to be submitted to treatments using sodium carbonate, lye or ultrasounds.
- The devices of the known art, while ensuring an excellent pipe cleaning, are very bulky and therefore not very suitable to be inserted in a pipe manufacturing and bending line.
- In addition, usually pipes are dipped into the above mentioned tanks in groups and the required time for the cleaning process is very long where compared with the operating speed of the bending machines disposed downstream of the tank along the production line. As a result, accumulation of pipes in the tanks occurs and the waiting time of the bending machines is very long.
- Finally, full cleaning of the pipe, both internally and externally is not strictly necessary for carrying out the mentioned bending operations.
- Under this situation, the technical task underlying the present invention is to conceive a pipe-cleaning device capable of obviating the mentioned drawbacks.
- In particular, it is an aim of the present invention to conceive a pipe-cleaning device enabling dust and other scraps present on the outer surface of each pipe to be efficiently eliminated.
- It is a further aim of the invention to provide a pipe-cleaning device adapted to execute such an operation in a short period of time.
- The present invention also aims at providing a compact pipe-cleaning device.
- In addition, the invention aims at proposing a pipe-cleaning device which is adapted to be inserted in a pipe production line along which subsequent working operations such as bending of the pipes themselves are contemplated.
- The technical task mentioned and the aims specified are achieved by a pipe-cleaning device having the features set out in one or more of the appended claims.

second jaws jaws active surfaces jaws engagement surface 5. - Still more preferably, sheet F is part of a ribbon N of cleaning material running along a predetermined feeding path H extending between the first and
second jaws - According to a preferred embodiment herein shown, the ribbon of cleaning material N is wound on a
supply reel 20 and extends along the predetermined feeding path H until a receivingreel 21, shown in Fig. 2. - In particular, the
supply reel 20 is mounted on a first rotatingshaft 22 rotatable about a respective axis I parallel to the first direction X and thereceiving reel 21 is mounted on a second rotatingshaft 23 rotatable about a respective axis J also parallel to the first direction X. - The first and second
