Definitions

  • the invention relates to a device for corrugating a pipe made of metal, which has as a finished product extending transversely to its longitudinal direction corrugation, which has a drivable by a first electric motor and rotatable in working position about its axis, annular corrugated head, with a radially is coupled inwardly of the same projecting, annular Wellerusion which is mounted adjustably in the shaft head in the radial direction ( EP 1 084 774 B1 ).
  • Such tubes are on the one hand well bendable because of the corrugation and on the other hand stable against radial forces acting on them. They can be used to transport fluid media, but also as coats or conductors for electrical and / or optical cables.
  • a corresponding pipe may for example consist of steel.
  • As a conductor it is used with advantage in high-frequency cables. It then preferably consists of copper.
  • the known device has a shaft head rotatable about an initially smooth tube with a Weller disc mounted off-center to the tube, which during operation of the device pushes a corrugation extending transversely to the longitudinal direction of the tube into the same.
  • a in the withdrawal direction of the same protruding hollow shaft is fixed, through which the tube is pulled after the Wellvorgang and which is rotatable together with the shaft head by an electric motor about its axis.
  • the hollow shaft takes with it firmly connected with its corrugated head, the Wellerusion presses the corrugation in the continuously moving in its axial direction through the corrugated head tube.
  • the corrugated head with connected Hollow shaft and mounted on the same rotor of the electric motor are combined in this known device into a unit which is movably mounted in the axial direction.
  • tolerances influencing the corrugating process can be compensated, which can occur during continuous production.
  • the shape of the corrugation, in particular the corrugation depth are measured, for example, when starting the device. If this form deviates from the specified dimensions, the Weller disk must be readjusted. For this purpose, the device must be stopped and restarted after the adjustment.
  • the invention has for its object to make the above-described device so that the shape of the corrugation of the tube can be changed even during production.
  • the Wellertial can be adjusted radially during production. It is therefore possible to accurately adjust the undulation depth of the pipe to be corrugated without having to stop the apparatus. This is particularly noticeable when starting the device advantageous, because the desired wave depth can be set very quickly without interrupting the operation. As a jumble starting lengths can be kept short.
  • the corrugation can also be carried out variably with this device.
  • the corrugation depth can be changed during production. It is also possible to produce tubes having portions without corrugation, which are connected by corrugated portions in which the tube is well bendable.
  • a differential gear which is connected to an electric servomotor.
  • the servomotor may preferably be turned on and off by a signal generated by a corrugator controlling unit.
  • the adjusting mechanism is activated, which advantageously has a bevel gear which can be adjusted by means of the holder and which is connected to the shaft plate via a threaded rod. If necessary, the servomotor can also be switched on and off manually.
  • a second electric motor can be used, which then rotates the holder at the same speed with which the shaft head is rotated when nothing is to be adjusted to the Welleremia. If necessary, the speed of the second electric motor is changed at short notice, whereby the speed of the holder is changed. As a result, the Welleremia is adjusted in the desired direction in the radial direction.
  • the device according to the invention is in Fig. 1 only reproduced purely schematically.
  • Fig. 1 serves only to explain the principle of construction and operation of the device. More details go from the Fig. 2 to 4 out.
  • annular shaft head 1 which is rotatable about its axis and to a first electric motor M 1 - hereinafter "motor M 1" - driven becomes.
  • a radially inwardly projecting from the same, also annular Wellerlude 2 is mounted, which preferably consists of stainless steel. It is adjustable within the corrugated head 1 in the radial direction and is used for impressing troughs in an existing metal pipe 3, which is pulled for example in the direction of arrow 4 through the corrugated head 1.
  • the Welleremia 2 is arranged eccentrically in the corrugated head 1. It rolls in the circumferential direction around the tube 3 or on the same during operation of the device.
  • the tube 3 may for example consist of copper, aluminum or steel, in particular stainless steel.
  • the Wellerront 2 may be designed to produce a helical corrugation in the tube 3 as a smooth annular disc. But it can also extend along a screw thread to produce an annular corrugation.
  • a holder 5 In the region of the corrugated head 1, a holder 5 is arranged, which is rotatable together with the corrugated head 1 about the axis A. It can be done accordingly Fig. 1 from a second electric motor M2 - in the following "motor 2" - are driven. On the holder 5, an adjusting mechanism 6 is mounted, which acts on the Welleremia 2 and optionally adjusted the same in the radial direction within the corrugated head 1. For such an adjustment, the rotational speed of the second motor M2 is changed briefly, whereby the rotational speed of the holder 5 is changed. The thus changed position of Verstellmechanismusses 6 is thus dependent, for example, on the speed of the holder 5.
  • the relative to the tube 3 and the axis A eccentrically arranged Wellerlitis 2 is moved up to the tube 3 until it rests against the surface at one point of its circumference.
  • the motors M1 and M2 and the discharge device for the pipe 3 are turned on.
  • the motor M 1 rotates the shaft head 1 with the washer plate 2 around the tube 3, which is moved by the trigger mechanism in the direction of the arrow 4 (or opposite).
  • the Wellerstrom 2 is now adjusted for example by hand by an operator in the radial direction. As a result, it generates a corrugation extending, for example, helically and transversely to the axial direction of the tube 3 in the same.
  • the depth of the corrugation or troughs is measured by a controlling unit or by hand.
  • the second motor M2 is turned on, through which the holder 5 is rotated around the axis A at the same speed as the wave head 1.
  • the two motors M1 and M2 can be connected to each other in the manner of an electric shaft. This is indicated by the dashed line 7.
  • the depth of the corrugation is measured immediately after the start of operation of the device. This can be done with an example optical and / or electrical unit, through which in a connected to the adjusting mechanism 6 control loop, the Weller disk 2 is automatically adjusted in the sense of compensation.
  • the adjustment of the Welleremia 2 but can also be done by hand.
  • the speed of the second motor M2 is briefly increased or decreased by a signal of the monitoring unit.
  • the speed of the second motor M2 can also be adjusted by hand.
  • the rotational speed of the holder 5 is then changed by the second motor M2.
  • the coupled with the same adjusting mechanism 6 adjusts the Welleremia 2 until the depth of the corrugation corresponds to the predetermined value.
  • a preferred embodiment of the device is in Fig. 2 shown.
  • the shaft head 1 with Welleremia 2 is here connected to a hollow shaft 8, which is rotated during operation of the device by the first motor M 1 about the axis A.
  • the hollow shaft 8 has for receiving the corrugated head 1 at one end of a Fig. 2 apparent Extension.
  • the holder 5 is here also designed as a hollow shaft 9 with an extension of the hollow shaft 8 encompassing extension. It is rotatably mounted within the device in a schematically indicated bearing 10 and on the hollow shaft 8 via bearings 1 1 and 12.
  • the adjusting mechanism 6 is in the in Fig. 2 illustrated embodiment equipped with a bevel gear 13, with which the hollow shaft 9 is engaged at its enlarged end.
  • the bevel gear 13 sits in accordance Fig. 4 on a threaded rod 14 which is rotatably mounted in the corrugated head 1 and connected to the Welleremia 2.
  • the bevel gear 13 is advantageously a gear, with which the corresponding equipped with teeth holder 5 meshes.
  • the adjustment mechanism 6 may also have a deviating from the illustrated embodiment construction, as long as it is ensured that a change in the rotational speed of the holder 5 and the hollow shaft 9 leads to a radial adjustment of the Wellersay 2.
  • the holder 5 or the hollow shaft 9 for actuating the Verstellmechanismusses 6, for example be moved in the axial direction, with unchanged speed of the holder. 5
  • a differential gear 15 Between the first motor M1 and the hollow shaft 9 is in the device according to Fig. 2 arranged a differential gear 15, the structure is basically known. Its different gears are stored in a basket 16. By the differential gear 15 ensures that the hollow shaft 9 rotates during operation at the same speed as the hollow shaft 8.
  • the basket 16 of the differential gear 15 engages in the illustrated embodiment, an electric servomotor 17 at. If the same is temporarily turned on, for example due to a deviation of the depth of the corrugation in the tube 3 of the predetermined value, the rotational speed of the gear 18 of the differential gear 15 and thus the rotational speed of the hollow shaft 9 is changed. This leads in the above-mentioned sense to the actuation of the bevel gear 13 and thus to the radial adjustment of the Welleractivity 2. Die in Fig. 2 between the individual drive elements and the driven components drawn gears are not provided with reference numerals as known per se machine elements. Instead of the gears also known belts or chains can be used.
  • the servomotor 17 can as well as for the second motor M2 after Fig. 1 described, by signals of the Welltiefe supervising or regulating unit or manually switched on and off.
  • the basket 16 of the differential gear 15 can be operated in principle without the use of a servomotor by hand, for example by means of a handwheel.
  • a second motor M2 is used instead of the differential gear 15, a second motor M2, as it is already in principle Fig. 1 evident.
  • the other structure of the device according to Fig. 3 is opposite Fig. 2 unchanged.
  • the adjustment of the Welleremia 2 via the bevel gear 13 is effected here by the second motor M2, as for the device according to Fig. 1 is described.
