Definitions

  • the invention relates, on the one hand, to a method for producing a stopper receiving at least two drawing plugs, delimited, on the one hand, by a drawing bar and, on the other hand, by a plug chamber delimited on the outer circumference of an outlet pipe when cascading pipes made of non-ferrous metals or their alloys.
  • the invention is directed to an apparatus for performing the method.
  • the starting pipe can be a press pipe or a rolled or a longitudinally welded pipe.
  • the outlet pipe is moved in several passes by means of drawing rings that are spaced apart from one another in the opening cross section, the drawing plugs of different sizes then each forming the corresponding abutment.
  • the wall thickness of the outlet pipe having a certain outside diameter must be dimensioned such that even taking into account manufacturing tolerances of the primary material such as uneven outside diameter, uneven wall thickness and ovality, the smallest pulling plug in diameter picks up until the takeover Abutment function can move freely in the plug chamber. If this is not taken care of, the pulling plug can be clamped in and the outlet pipe can be torn off.
  • the invention has for its object to improve this method and also to provide a suitable device for performing the method that more material can be used per output tube and consequently more finished tube can be achieved without sacrificing quality is.
  • a plug chamber with a wall thickness is created immediately behind the drawing bar, which is dimensioned smaller than the wall thickness of the rest of the starting pipe, with the pipe outside diameter remaining the same.
  • the inside diameter of the plug chamber taking into account the diameter reductions during the drawing process and the resulting increase in wall thickness, has been brought to an amount which guarantees the freedom of movement of even the smallest diameter drawing plug up to the point in time at which this drawing plug interacts with the drawing ring assigned to it.
  • an outlet pipe that can be dimensioned larger in wall thickness than the outlet pipe previously used and in which the inevitable manufacturing tolerances in the outside diameter, in the wall thickness and in ovality with regard to the freedom of movement of the in the diameter of the smallest drawing plug no longer play a role.
  • an extension of the outlet pipe in the area of the plug chamber is associated with the stretching of the plug chamber by approximately 20%. This reduces the length of the pipe section required to generate the drawing die. Also the diameter of the Drawbar kept smaller. As a result, the waste of material caused by the drawbar can advantageously be reduced.
  • a clamping and denting unit on the one hand and a mandrel and ironing unit on the other are assigned to one another in a function-optimized manner.
  • the clamping and denting unit has radially movable clamping jaws and Dell tappets. With the help of the clamping jaws, an exit pipe can be fixed locally, so that, using the mandrel forming part of the mandrel and ironing unit, a length section protruding beyond the clamping and dent unit in the direction of passage of the exit pipe can be thorned out in such a way that both the inside diameter and this area as well as enlarge the outside diameter.
  • the outer diameter of the thickened length section is stretched to the original outer diameter of the initial tube with the mandrel remaining in the initial tube.
  • the clamping and denting unit and the one assigned to it can be used Dell plunger dents are generated on the outlet pipe, which forms a limitation of the subsequent plug chamber. After the drawing plugs have been introduced into the plug chamber, the draw bar is ultimately formed on the free end of the outlet pipe.
  • the embodiment according to the features of claim 3 provides two mechanically coupled hydraulically actuatable cylinders which have piston rods which can be extended in opposite directions.
  • the cylinder housings are fixed in place.
  • the piston rod of the mandrel cylinder which can be extended in the direction of the output tube or the clamping and denting unit, is connected to the mandrel, which serves to widen the end section of the output tube and serves as an abutment for the ironing ring when this end section is stretched.
  • the piston rod of the ironing cylinder which can be extended in the other direction, is connected to the ironing ring via a linkage which runs parallel to the longitudinal axes of the cylinders.
  • the ironing ring is arranged at the free end of the rod.
  • the outlet pipe is first moved beyond the clamping and denting unit with a length section that takes into account the axial extension of the plug chamber and the drawbar. Then the clamping jaws are placed on the outlet pipe and the outlet pipe is thus fixed locally.
  • the starting position of the mandrel and ironing unit is such that the mandrel cylinder is retracted and the ironing cylinder is extended. After fixing the output pipe, the ironing cylinder is then in the direction of entry acted upon, so that the ironing ring slides along the end section of the output tube projecting beyond the clamping and denting unit in the direction of passage. After reaching the end position, the mandrel cylinder is loaded in the direction of extension and the mandrel is pushed into the outlet tube, increasing the inside and outside diameter. When the mandrel has reached its end position, the ironing cylinder is loaded in the direction of extension and the outer diameter of the lengthened mandrel is stretched to the original dimension. The mandrel remains in the exit tube.
  • the mandrel cylinder is also loaded in the entry direction and the mandrel is pulled out of the exit tube. Then the Dell tappets are moved radially inwards and two dents are created with a 180 ° offset. Ultimately, the drawing die is formed on the free end of the length section provided with a reduced wall thickness, if the drawing plugs have previously been inserted into the plug chamber produced by the thickening.
  • the drawing plugs 2, 3, 4 required to carry out the method are, as can be seen in FIG. 9, introduced loosely, ie freely movably, into a plug chamber 12, which is located at the front end in the direction of passage DR of the outlet pipe 1 between a drawing bar 13 and two, the cross-section of the output tube 1 dimples 14 is located.
  • a device 15 is used to produce this plug chamber 12, as can be seen in more detail in FIGS. 2 to 6.
  • This device 15 (see FIG. 2) comprises a clamping and denting unit 16 for the outlet tube 1 and a mandrel and ironing unit 17 which is arranged coaxially with the clamping and denting unit 16 and can be relatively displaced relative to it.
  • the clamping and denting unit 16 is provided with radially movable clamping jaws 18, which serve for the local fixation of the outlet tube 1. With the jaws 18 brackets 19 are connected, which carry Dellst Congressel 20 in a diametrical offset, which are radially displaceable in the direction of the output tube 1.
  • the mandrel and ironing unit 17 comprises two hydraulically actuated cylinders 21, 22, the housings 23, 24 of which are fixed locally and coupled to one another on the end face.
  • the mandrel cylinder 21 which is closer to the clamping and denting unit 16 has a piston rod 25 which can be extended in the direction of the clamping and denting unit 16 and which carries a mandrel 26.
  • the other ironing cylinder 22 has a piston rod 27 which can be extended in the direction of passage DR of the output tube 1.
  • a crossbar 28 is fastened to the free end of the piston rod 27.
  • the cross member 28 is operatively connected via a linkage 29 running parallel to the cylinders 21, 22 to an ironing ring 30 which, in the starting position of the device 15 according to FIG. 2, is located approximately at the free end of the mandrel 26.
  • the outlet pipe 1 with an outer diameter AD of 80 mm and a wall thickness D of 5 mm is first moved so far through the clamping and denting unit 16 that the clamping and Dent unit 16 protrudes a length section 31, which enables the plug chamber 12 and the draw bar 13 to be manufactured. If this position is reached, the output pipe 1 is fixed locally with the help of the clamping jaws 18.
  • the ironing cylinder 22 is now acted upon in the entry direction.
  • the ironing ring 30 slides along the outer circumference of the end section 31 of the output tube 1 to be formed up to the position lying on the end face of the clamping jaws 18.
  • the mandrel cylinder 21 is acted upon in the extending direction, so that the mandrel 26 penetrates into the approximately 365 mm long end section 31 and, as can be seen in FIG. 7, both the inside diameter ID of 70 mm and the outside diameter AD from 80 mm of the output pipe 1 to the inside diameter ID1 of 72 mm and the outside diameter AD1 of 82 mm.
  • the ironing ring 30 is moved in the direction of travel DR of the output pipe 1, with the mandrel 26 remaining in the end section 31 serving as an abutment, the outer diameter AD1 of the end section 31 as shown in FIG. 8 to the original outer diameter OD reduced by 80 mm.
  • the inner diameter ID1 expanded to 72 mm, remains.
  • the end section 31 has been lengthened from approximately 365 mm to approximately 450 mm due to the stretching from the initial length.
  • the mandrel and ironing unit 17 is now again in the starting position according to FIG. 6, as shown in FIG. 6. This now allows two diametrically opposite dents 14 (FIG. 9) to be moved by radially inward movement of the Dell tappets 20 according to FIG To produce the outer circumference of the outlet pipe 1, so that herewith also reduces its inner cross section and one of the boundaries of the plug chamber 12 is thereby formed.
  • the pull plugs 2, 3, 4 are introduced into the plug chamber 12 and then the draw bar 13 is molded on.
  • the output pipe 1 is thus prepared for a triple pull through the drawing cascade 11.
  • the pull plug 2 reaches the area of the pull ring 5, the dents 14 become effective and cause the pull plug 2 to move into the pull ring 5 up to the pull position. Now the wall thickness of the outlet pipe 1 is also reduced. This situation is illustrated in FIG. 11. It can be seen here that the drawing plugs 3, 4 are still in the area of the plug chamber 12 whose wall thickness has not yet been reduced. Immediately behind the pull plug 3, however, the area of the outlet pipe 1 begins with a reduced wall thickness. Here, two further dents 14 are then also placed at a distance from the drawing plug 3 in order to limit the displacement of the drawing plug 3 in the plug chamber 12 during the following train.
