  • the invention relates to a method and a device for producing conical pipe sections on cylindrical pipes of screw foundations.
  • the invention relates to a method and an apparatus for producing conical pipe sections on cylindrical pipes of screw foundations.
  • Methods and apparatus for producing conical sections on cylindrical, in particular metallic, tubes for producing screw-in foundations for holding components in the ground are known.
  • the conical sections can be produced in different ways, for example by welding prefabricated molded parts or by hammering preferably seamless cylindrical tubes (see EP 1 105 597 B1). Also, the production by rolling preferably seamless tubes into consideration. According differently, the devices used for this purpose can be designed. However, the methods mentioned are complicated.
  • the preparation of prefabricated moldings requires a variety of steps (making the moldings, for example, by cutting, then bending and welding the seams or the like).
  • the production by hammering or rolling cylindrical tubes as such although problem-free, but requires a lot of equipment for the Hämmer- or the rolling device.
  • the per se conventional hammering is associated with high wear and corresponding noise development.
  • the object is accordingly to provide a method by means of which such conical sections can be produced on cylindrical tubes or conical sections of cylindrical pipes for screw foundations in a simple manner and inexpensively, as well as to provide a device for carrying out such a method, which as such with justifiable effort can be produced and at the same time allows for economical and fault-free production of erfund though with low personnel costs.
  • the cone-shaped pipe sections are produced by drawing cylindrical, preferably seamless pipes.
  • the device according to the invention serves to carry out this method.
  • the deformation device comprises a machining tool which consists of a plurality of pressure roll disks or pressure roll disk segments. These are arranged radially about a longitudinal axis of a receptacle for the cylindrical tube to be pulled. They are further arranged to pivot about the longitudinal axis of the recording transversely and tangentially extending axes and are designed such that their outer peripheral surfaces form a cone in their settlement.
  • the device further comprises a pulling device. This serves to pull the tube and / or the machining tool along the Lssensache such that a relative movement between the pipe and the machining tool takes place, which causes the pressure roll disks or pressure roll disk segments roll with their shaping outer peripheral surfaces on the tube and so in their interaction the conical or teilkonische shaping their settlement transferred to the pipe.
  • a pulling device serves to pull the tube and / or the machining tool along the Lssensache such that a relative movement between the pipe and the machining tool takes place, which causes the pressure roll disks or pressure roll disk segments roll with their shaping outer peripheral surfaces on the tube and so in their interaction the conical or teilkonische shaping their settlement transferred to the pipe.
  • the relative movement between the machining tool and the pipe to be drawn can be produced in different ways. It can be held stationary the machining tool and the pipe can be pulled by means of the pulling device. Alternatively, the tube can be held stationary by means of a holding device and the processing tool can be pulled by means of the pulling device. Finally, even both the tube and the machining tool may be movable relative to one another in the relative movement. In order to ensure a homogenization of the cylinder shape arising during the drawing, in particular to minimize burrs between the individual pressure roller disk impressions on the workpiece, it can be provided that the pipe or also the machining tool during pulling additionally around its longitudinal axis (the longitudinal axis of the receptacle or the pipe). is turned. For this purpose, the holding and pulling device can at the same time be configured as a rotating device or the machining tool can be rotatable.
  • the rotation of the tube or the machining tool must not be a 360 ° rotation.
  • roll number x 2 which can be executed stepwise or oscillating is sufficient.
  • the device In order to hold the tube, pull and possibly rotate, the device has one or more clamping devices for clamping the tube.
  • the clamping devices may be designed to be self-locking so that their holding force increases when pulling proportional to the applied tensile forces.
  • the drawing device conveniently has a linear guide for guiding the tube or tubes and / or the holding, pulling and rotating device and / or the machining tool along the longitudinal axis of the receptacle .
  • the pressure roller disks or pressure roller disk segments are biased by at least one spring element such that they rest on the introduced into the receptacle tube under tension frictionally. This is ensured according to the invention as follows:
  • the pressure roll disks or pressure roll disk segments are biased by the at least one spring element so that they are in the position of the narrowest cross section of their settlement. If a tube is introduced into the receptacle defined by the outer circumferential surfaces of the pressure roll disks or pressure roll disk segments for its processing, it encounters this narrowest cross section of its development. Upon further insertion of the tube into the machining position, it urges the pressure roller disks or pressure roller disk segments against the force of the at least one spring element in the direction of the position of the largest cross section (or of the pipe cross section corresponding cross section) the settlement of their outer peripheral surfaces, in which the processing of the pipe by pulling in the opposite direction begins.
  • the spring element may be, among other things, at least one gas spring or a controlled pneumatic cylinder.
  • this is done by a toothing of the discs or disc segments.
  • This may for example be positioned near its outer peripheral edges.
  • at least 18, preferably 24, more preferably 28, 32 or 36 pressure roll disks or pressure roll disk segments are provided.
  • This plurality of discs ensures accurate, uniform machining of the workpiece. It is important that burrs on the cone to be formed are avoided. Therefore, the outer peripheral surfaces of the pressure roller disks or pressure roller disc segments in their settlement in turn must fit seamlessly together. To ensure this, the disc edges are chamfered radially.
  • the outer peripheral surfaces of the discs or disc segments In order for the outer peripheral surfaces of the discs or disc segments to form a cone tapering in the opposite direction to the processing direction, they must taper towards the apex of the cone. In the case of the multiplicity of pressure roll disks or pressure roll disk segments provided according to the invention, they may therefore be so narrow towards the cone tip that the stability necessary for absorbing the high deformation pressures would be jeopardized. To counteract this, according to the invention it can be provided that the number of disks participating in the deformation is reduced by the course of the deformation process towards ever smaller pipe diameters. This is ensured by virtue of the fact that individual or groups of pressure roll disks or pressure roll disk segments can be radially disengaged during the drawing of the pipe in relation to the remaining pressure roll disks or pressure roll disk segments.
  • the pressure-roller disks or pressure-roller-disk segments can be exchangeable for disk sets of other calibers.
  • the application assumes that normally a cone-shaped section is produced in a single drawing operation. However, this can lead to the limits of their load capacity, in particular in the case of particularly strong cylindrical tubes or in the case of particularly strong deformations (high gradients of the conical section to be formed).
  • the invention provides that the pulling device is designed for a multi-stage or multi-step pulling. This means that the desired cone is not produced in one operation, but the tube is first introduced in a first step only over part of the distance of the intended cone-shaped deformation in the recording and pulled so that initially only a smaller than the final intended deformation is achieved, and then the tube in one or more further steps Lower part is inserted into the receptacle and pulled until the desired final shape of the cone is made.
  • burr formation on the cone shaped portion should be excluded or kept within an acceptable range because the outer peripheral surfaces in the settlement are seamlessly abutted so that there should be no space for burr formation ,
  • a rotating device for rotating the tube and / or or of the machining tool about the longitudinal axis of the receptacle during the drawing or between the multiple drawing steps of a multi-step drawing in order to even achieve a homogenization of the cone shape, a rotating device for rotating the tube and / or or of the machining tool about the longitudinal axis of the receptacle during the drawing or between the multiple drawing steps of a multi-step drawing.
  • the invention further relates to a method for producing conical sections of cylindrical pipes of screw foundations by pulling by means of a device according to one of claims 1-16.
  • this method can also be designed in such a way that the drawing takes place in several steps or steps (multi-step). This is done in such a way that the cylindrical tube for the first drawing stage is only partially inserted into the receptacle and then pulled, then introduced for a second drawing stage a little further into the receptacle and then pulled to finally, in about one third drawing stage to be fully inserted into the receptacle and then pulled so that in this step, the outer peripheral surfaces of the pressure roll disks or Druckwalzenusionnsegmente completely roll on the pipe and completely transfer their execution form on the pipe.
  • a pulling device is to be provided, which allows such a multi-step pulling.
  • the method may include rotating the tube about its longitudinal axis during the drawing and / or between several consecutive drawing steps.
  • the rotating device is provided.
  • the method may be further configured such that to produce multiple conical sections of different cross-section and / or different pitch on a cylindrical tube, the plurality of drawing steps are sequentially applied at different locations along the length of the cylindrical tube.
  • the pulling device must be such support multi-step drawing, for example by an adjustable cooperation of pulling and forming device such that either a plurality of deformation means are arranged one after the other and the individual deformation means each have different sets of pressure roll disks or pressure roll segments and the drawing device feeds the pipe to be deformed the respective deformation means, or that the pulling device and the pressure roll disks or segments cooperate in such a way that the pipe to be deformed is fed in succession to the areas corresponding to the respective degree of deformation to be achieved to the pressure roll disks or pressure roll segments.
