Definitions

  • the present invention refers to the field of surface finishing of pipes.
  • a brushing treatment on the outside surface of pipes by means of rotating brushes is known, in lines for the production of pipes starting from sheet metal, using a brush-holding head that turns around the pipe.
  • the pipe advances without rotating.
  • the finishing obtained is not precise and therefore the procedure cannot be used when a precision finishing is required.
  • a further drawback is the need to lubricate the pipe with plenty of water in the area of friction thereof with the belt, and the use of water or other liquid for lubrication and cooling leads to the production of sludge, which is difficult and laborious to dispose of. Furthermore, water is a cause of deterioration of the fixed or moving mechanical parts and the sludge produced must be manually removed from the line by the operators, with a resulting waste of time.
  • the procedure comprises the stages of operating on a pipe advancing along its own axis and rotating with a plurality of lamellar wheels or brushes placed alongside the pipe and rotating around an axis which is generally parallel to the axis of the pipe.
  • the apparatus comprises a bed of idle rollers supporting the pipe, a brush-holding sleeve mounted on a support adjustable in position with respect to the pipe bed, means for causing the pipe to advance and to rotate and means to determine the position of the brush-holding sleeve.
  • the invention makes it possible to overcome the aforementioned drawbacks, in particular to obtain an excellent level of surface finishing of the pipe (from satin finishing to polishing), and to avoid overheating and the resulting deformations of the pipe, though without requiring the use of cooling liquids.
  • an apparatus for surface finishing of pipes is generally designated 10 and comprises, on a bed 12, a pipe supporting and feeding bed, designated 14, and a finishing unit, hereunder also called a grinding unit, designated 16.
  • T The pipe under production will hereunder be denoted generically by T; in Figure 1 a maximum diameter pipe T1 and a minimum diameter pipe T2, such as can be finished with the apparatus of the invention, have been drawn.
  • the pipe supporting and feeding bed 14 comprises a plurality of roller assemblies 18, each comprising one or more rollers or wheels 20 idle around generally horizontal axes a 20.
  • the roller assemblies are generally disposed on two rows, offset or in a quincunx, that is to say one on one side and the next, shifted longitudinally by a distance, on the other side of a runway for the pipe, which they define.
  • Each roller assembly 18 comprises a fixed frame 20 fixed to the bed and a moveable frame 24 thereon, rocking around a horizontal axis a 24 under the control of a cylinder-piston 25.
  • the rocking controlled by the cylinder-piston assemblies 25 disposes the frames 24 in a more or less upwardly widened position and, consequently, sets the rollers in a position more or less close to each other to adapt them to pipes to be treated of different diameters.
  • an adjustable frame 26 bearing the roller, which can be rotated, by not illustrated means, around the respective vertical axis a 26 to dispose the respective roller at the desired angle with respect to the axis of the pipe.
  • a brush-holding shaft or sleeve 30 of the grinding unit 16 ( Figures 3, 5) is supported.
  • the brush-holding sleeve has a horizontal axis a 30 parallel to the axis a T of the pipe and is rotatably supported, through two end universal joints 33 and 33', on the side arms 34 and 34' of a rocking arm structure 35 of the unit 16.
  • the arms 34, 34' are each mounted on a support 36, respectively 36', fixed to the bed, by means of a pivot part 37 ( Figure 6) which defines a horizontal rocking axis a16 for the unit 16.
  • the arm 34 of the structure carries a motor 40 for rotation of the brushes, visible in Figures 2 and 7.
  • the motor 40 has a drive shaft 41 which bears a drive pulley 42.
  • a belt 43 transmits the motion to a driven pulley 44 integral with the pivot of a universal joint 33, of the end universal joints of the brush-holding shaft.
  • the unit 16 rocks therefore around the axis a 16 defined by the pivots 37.
  • an element of a cylinder-piston assembly 48 acts on the part of the structure 34 opposite the brush-holding shaft.
  • a linear transducer 50 of the optical or incremental type, per se known, is also mounted between the bed and the same part of the brush-holding structure to allow adjustment of the position of the brushes with respect to the pipe in view of the diameter of the pipe and of the wear of the brushes.
  • the brushes used are preferably lamellar rotating brushes ("wheels"), available on the market and denoted by S in the figures.
  • Said lamellar wheels comprise a body, generally of plastic material, and radial foils extending from the body, generally consisting of cotton or polyester cloths, or of wheels of different materials that have abrasive incorporated, with or without abrasive powders applied.
  • Lamellar wheels preferably from 10 to 500 mm in diameter and lengths from 100 to 1000 mm can be used. The wheels are locked in a pack on the sleeve, possibly with a longitudinal gap between wheels or groups of wheels.
  • the pinch roll assembly which can be seen in Figures 3, 4 and 7 and is generally designated 60, comprises a pinch roll 61 coated with a layer of material suitable to create a drawing or gripping contact on the pipe, for example a rubber-type material that can grip the pipe and is integral with a shaft 62 taking its drive from the drive shaft of a motor 63.
  • the assembly is supported by a rocker arm 66 mounted rocking on an upright 67 fixed to the bed.
  • the position of the roller with respect to the pipe is determined by means of a cylinder-piston assembly 68, connected to the bed and to the arm 66.
  • Feeding of the pipe is determined by rotation thereof, due to the pinch roll, in contact with the rollers 20 disposed with their axes oblique with respect to the axis of the pipe.
  • Reference numeral 70 denotes a dust suction slit.
  • An air-cooling tunnel (not illustrated) can be provided along the course of the pipe. It is not necessary to use cooling liquids.
  • Reference numeral 74 denotes a sensor to detect the presence of the pipe.
  • the surface finishing that is obtained is good and uniform over the whole pipe, since the brushes are brought nearer to the axis of the pipe as they wear and no overheating and consequent deformations occur.
