Definitions

  • the invention relates to an apparatus and a method for producing cold pilgered tubes by means of a rolling mill, comprising a rolling mandrel mounted on at least one mandrel abutment and at least two externally applied to the outside of the forming tools, preferably outer rollers, and a measuring device for determining the wall thickness of the tube during the forming process.
  • the cold pilgering of pipes is a process for the further processing of seamless pipes from an original format into a final format.
  • the aim of the civilage is to reduce the outside diameter and wall thickness of seamless tubes.
  • the starting material the so-called tube blanket
  • the tube blanket usually passed through a pair of rollers, which has a conical calibration and performs a rotational and feed motion intermittently on the tube blank.
  • a rolling mandrel is placed in the interior of the billet.
  • tubes are thereby produced while maintaining particularly close dimensional tolerances of up to 5/100 mm.
  • pipe samples were randomly taken and measured to ensure quality control after the forming process had been completed. If the wall thickness threatened to leave the tolerance range or had already left, the rolling mill was previously shut down and corrected the position of the rolling mandrel. However, this meant that rapidly occurring changes in the wall thickness remained undetected and the rolling mill had to be regularly stopped for dimensional correction. Also, a confirmation of a successful dimensional correction was only possible if at least one whole further tube was reshaped.
  • a nondestructive measurement of the deformation result taking place during the forming process would accordingly be achievable, for example, using conventional ultrasonic measurement technology. Disturbing this, however, on the one hand, the particularly low workpiece geometry and very tight tolerance specifications and also the adhering to the workpiece lubricating film inevitably and inevitably passes through the forming process on the workpiece surface.
  • the object of the invention was therefore to provide an automatable production method and a device suitable for this purpose, which are capable of enabling the positional adjustment of at least one forming tool during cold pilgering on the basis of measured data obtained during the forming operation.
  • a position adjustment device is operatively connected to the mandrel abutment and also connected to the measuring device. Moreover, the connection of the position adjustment device to the measuring device preferably takes place via a control device, which is particularly preferably connected to a data memory for setting and / or operating parameters. This makes it possible that measured data recorded during the forming process may possibly influence the continuous forming process online and preferably almost without delay. This is done according to the invention by the actuation of the position adjustment device, via which the position of the rolling mandrel can be adjusted. This not only means that detected errors can be corrected almost immediately, but also the effects of the position adjustments on the rolling process as a whole can be tracked almost immediately and possibly corrected later.
  • a deviation of the wall thickness of a predetermined value or a tolerance range is determined during the forming process. This is achieved particularly advantageously by balancing the measurement data with specifications and comparison data stored in a control unit and in particular its memory.
  • a device is provided which automatically monitors compliance with the required tolerance over the entire circumferential process and preferably also ensures the initiation of suitable measures.
  • the measuring device is preferably a laser ultrasound (LASUS) measuring device, by means of which a virtually non-destructive and secure online measurement of the wall thickness of the cold pilgered pipe with particularly easy to control means and to achieve very accurate measurement results is possible.
  • LASUS laser ultrasound
  • the wall thickness is not determined only at a fixed position of the pipe. Rather, the cold pilgering process causes a regular twisting of the tube about its longitudinal axis. Thus, only by the preferred fixed arrangement of a measuring device and thereby taking place relative movement of the tube to this measuring device, a sweep of the measurement over the entire circumference of the formed tube. Moreover, it is preferred if not only a measurement is performed at a particular location of the pipe, a plurality of measurements, for example, while maintaining a predetermined frequency, performed over the entire forming process away. Thus, the determination of the acquired measurement data also minimizes the influence of any measurement errors by simple means.
  • the rolling mandrel is mounted on at least one mandrel abutment, which has at least one clamping wedge over which both the position adjustment of the rolling mandrel and its fixation in a predetermined position can be effected.
  • the movement of the at least one clamping wedge is effected by means of a clamping cylinder and / or a spindle.
  • the setting is infinitely variable in any position.
  • the rolling mandrel is adjustably arranged in the rolling mill according to the invention, but also the forming tools, preferably outer rolls, acting on the outside of the pipe are provided so that they are likewise adjustable.
  • suitable adjusting means of the outer rollers of the roll gap can preferably be set arbitrarily and possibly readjusted to create in cooperation with the rolling mandrel a tube with the most accurate roundness and the smallest possible deviations from the predetermined outer diameter and wall thickness value.
  • At least one forming tool acting on the outside of the pipe preferably an outer roll, also acts connected to the measuring device. This ensures that the position adjustment and readjustment of all forming tools involved in the forming process can preferably be achieved fully automatically when all of the forming tools have the measurement data recorded by the measuring device ready.
  • a method of producing cold pilgered tubes by means of a rolling mill which comprises a rolling mandrel mounted on at least one mandrel abutment and at least two forming tools engaging externally of the tube and a measuring device for determining the wall thickness of the tube during the Forming process includes.
  • at least one position adjustment device is connected to the measuring device via the at least one mandrel abutment and then carries out a positional adjustment of the rolling mandrel when the measuring device detects a deviation of the wall thickness from a predetermined value or from a tolerance range.
  • the wall thickness is determined over the entire circumference of the tube, in order to be able to determine the uniformity of the wall thickness and, if appropriate, also the shape of the tube on the one hand.
  • At least one, preferably exactly one, fixed measuring device is provided, via which the measurement of the wall thickness is also possible via the entire circumference of the tube can be done.
  • the recording of measured data over the entire circumference of the tube can be effected with particularly simple means.
  • At least one forming tool acting externally on the pipe is adjusted in addition to the rolling mandrel in order to be able to counteract deviations in the wall thickness from a predetermined value or from a tolerance range.
  • the FIG. 1 shows a device 1 for producing cold pili pipes, wherein the rolling mill used for this purpose has a rolling mandrel 2 mounted on a mandrel abutment 3, and a rolling stand 4 with outer rollers 4a and 4b mounted therein. Under the action of the device 1, the forming of a tube blank, which runs from left to right through the device 1 takes place. Between the tapered rolling mandrel 2 and the outer rollers 4a, 4b, the deformation takes place to a tube 8 with a constant wall thickness, which can be determined in the measuring device 5.
  • the measuring device 5 is connected via a control unit 6 with a position adjustment 7 of the mandrel abutment 3 and can on actuation of the position adjustment 7, a movement of the rolling mandrel 2 both in the direction of arrow 9 and with respect to the inclination adjustment of the rolling mandrel 2 to the nip between the outer rollers 4a , 4b effect.
  • FIG. 2 is a schematic view of the position adjustment 7 of the device 1 according to the invention in section AA FIG. 1 ,
  • the mandrel abutment 3 is fixed by means of clamping wedges 7a, 7b.
  • the force required for fixing is in the embodiment after Fig. 2 applied by a pressurizable in the direction of the double arrow 10 hydraulic cylinder 11 as a clamping cylinder.
  • For the fine correction of the finished tube wall thickness during production of the rolling mandrel 2 is typically moved in accordance with arrow 9 in and opposite to the rolling direction.
  • the automatic adjustment is carried out, for example, by the fact that the clamping wedges 7a, 7b are released against unintentional axial movement locking clamping cylinder so far that the mandrel abutment 3 by an adjusting motor 12 via a Spindelhub réelle 13 (see. Fig. 1 ) can be moved in or against the rolling direction.
  • the clamping cylinder is again subjected to the normal clamping pressure and carried out the forming process in the usual way.
  • the entire adjustment procedure can not only be done automatically, but also be done during the rolling process itself.
