Definitions

  • the present invention relates to a device for cold-pressing a conical thread onto at least one conically shaped end of a reinforcing steel, comprising a guide sleeve with a conical interior, the wall of which has a plurality of longitudinal guide grooves with a T-shaped cross section, which is directed against the longitudinal axis of the interior are inclined at an angle, and a plurality of jaws, which likewise have a T-shaped cross section and are held displaceably in the guide grooves, and a pressure stamp which is provided for displacing the jaws in the longitudinal direction of the conical interior.
  • Conical threads enable a large number of threads to be engaged with one or just a few turns. They are therefore particularly suitable as fastening threads if the threaded bolt and / or the nut can only be turned with great effort when tightening or should only be displaced slightly in the axial direction.
  • a known use of conical threads is the mechanical connection of the butt-jointed ends of reinforcing steels for concrete. The ends of the reinforcing steels, which are provided with conical external threads, are screwed together using a nut piece which has two conical internal threads. Such nut pieces are described, for example, in US Pat. Nos.
  • a device for cold working a relatively small metal part is known from US Pat. No. 3,999,417.
  • This device has a plurality of jaws arranged around a longitudinal axis, the inner surfaces of which face towards the longitudinal axis in the working position, i.e. when the jaws are against each other, form a mold.
  • the device further has two press rams arranged in the longitudinal axis, of which at least one is displaceable in the axial direction in order to deform a metal part inserted between the jaws.
  • the jaws are guided in grooves that are inclined to the longitudinal axis, so that any displacement of the jaws in the longitudinal direction also causes a displacement in the radial direction.
  • This device is not suitable for pressing conical threads, even if the inner surfaces of the jaws are provided with a corresponding profile, which is known from US Pat. No. 2,652,577 because the device is not suitable for pressing the jaws into one with the required force Pressing in a workpiece from a tough material.
  • the present invention was therefore based on the object of providing a device for pressing a conical external thread, in which the press jaws are arranged and designed in such a way that the force exerted by the press jaws on the workpiece is greater than the force acting on the press jaws.
  • a device of the type mentioned at the outset which is characterized in that the jaws are attached to the pressure ram so as to be displaceable in the radial direction and, for use as press jaws, have an inner surface which is inclined at an angle to the longitudinal axis of the interior which is opposite to the angle of inclination of the guide grooves, and have a profile which corresponds to individual segments of a nut piece for the conical thread to be pressed.
  • the device according to the invention enables conical external threads to be produced in which the fiber course in the workpiece is not interrupted as a result of the non-cutting processing, but rather the partial fiber compaction brought about by the deformation of the material brings about an advantageous surface consolidation.
  • the conical external threads produced with this device are therefore characterized by a higher load capacity and less susceptibility to corrosion as well as an increased fatigue strength.
  • the device according to the invention is therefore very well suited for pressing conical external threads into reinforcing steels and in particular into those reinforcing steels which are intended for structures subject to fatigue, such as bridges.
  • the device shown in FIGS. 1 and 2 in longitudinal or cross section contains a hydraulic press 10 which interacts with a threaded press head 11.
  • the hydraulic press consists of a hydraulic cylinder 12 in which a piston 13 is slidably fitted in the axial direction.
  • the cylinder base 14 has a bore 16 which is provided for connecting a hydraulic line which connects the interior 17 of the cylinder to a hydraulic pump.
  • the hydraulic pump and line are known to any person skilled in the art, which is why they are neither shown nor described.
  • a piston rod 18 is formed on the surface facing away from the working surface of the piston 13, the free end of which protrudes from the cylinder through the central opening of an annular cylinder cover 19.
  • a pressure stamp 21 is attached, the diameter of which is larger than the diameter of the piston rod.
  • a compression spring 22 is placed around the part of the piston rod located in the cylinder, the ends of which rest on the rear surface of the piston or on the inner surface of the cylinder cover.
  • the threaded press head 11 contains a guide sleeve 26 which is screwed to the hydraulic press 10 in the region of the cylinder cover 19.
  • the guide sleeve has a conical interior 27, the larger diameter or base circle of which is adjacent to the plunger 21 and the smallest diameter or cover circle of which forms an opening 28 in the top surface of the threaded press head facing away from the hydraulic cylinder.
  • four grooves 30, 31, 32, 33 offset by 90 ° and with a T-shaped cross section are machined.
  • the grooves run parallel to the surface lines of the conical interior and are therefore inclined at an angle a with respect to the longitudinal axis 45 of the threaded press head.
  • the press jaws have a T-shaped cross section with a two-armed guide bar and a press ram protruding therefrom.
  • Each press jaw is slidably mounted with its guide bar in an associated groove in the guide sleeve in the longitudinal direction of the press head and is connected to the plunger 21 by means of a screw 40, 41.
  • the screws are guided in the pressure ram in radial slots 42, 43 in order not to block the displacement in the radial direction superimposed on any displacement of the pressing jaws in the axial direction.
  • the inner surfaces of the press jaws facing the center of the conical interior 27 are inclined at an angle ⁇ with respect to the longitudinal axis 45.
  • the direction of inclination of this angle ⁇ is opposite to the direction of inclination of the angle a, and the angle ⁇ is smaller than the angle a.
  • the inner surfaces of the press jaws are circular in cross-section and have a surface profile that corresponds to a corresponding part of a nut piece for the conical external thread to be pressed.
  • the end of a workpiece which is to be provided with a conical external thread is first conically formed.
  • this conical shape preferably has the same angle ⁇ as that should have conical external threads to be produced.
  • the conical formation can be formed by machining, for example by turning or grinding, or by non-cutting machining such as pressing or hammering.
  • this processing does not significantly change the material properties and in particular the tensile and flexural strength, and that there are no hairline cracks in the surface, which can increase to a breaking point when the thread is later loaded.
  • the hydraulic press 10 is relieved of pressure, so that the spring 22 pushes the piston 13 back into its rest position until the pressure ram 21 abuts the cylinder cover 19 and the pressing jaws 35, 36, 37, 38 as far as possible are drawn into the conical interior 27 and because of the inclined guide grooves 30, 31, 32, 33 have the greatest possible distance between their inner surfaces.
  • the conically shaped end of a workpiece for example in the form of a reinforcing steel 46, is guided through the opening 28 of the guide sleeve 26 in the direction of the pressure plunger 21 until the conical shape lies against the inner surfaces of the press jaws along its entire length.
  • pressurized fluid is introduced into the interior 17 of the cylinder 12, which displaces the piston 13 in the direction of the cylinder cover 19.
  • the plunger 21 is also moved and from this the pressing jaws 35, 36, 37, 38 are displaced in the direction of the opening 28 of the guide sleeve 26.
  • the guide grooves 30, 31, 32, 33 for the press jaws are inclined with respect to the axis 45 of the press head, the press jaws are simultaneously pushed against one another in the radial direction during this axial displacement.
  • the inclined plane formed by the guide grooves has the effect that the force acting on the pressure jaws in the radial direction is several times greater than the force of the pressure stamp 21 acting in the axial direction.
  • the inner surfaces of the pressure stamp become conical molded end of the reinforcing steel pressed in until all partial surfaces of the relief-like inner surfaces of these jaws abut the reinforcing steel, or the lateral edges of the inner surfaces of adjacent pressing jaws lie against one another.
  • the tapered end of the reinforcing steel with the press-in thread is rotated between the loosened press jaws in order to cut off a burr which may have been raised when the jaws were pressed into the steel on the lateral edges of the inner surfaces of the press jaws.
  • the hydraulic fluid is released from the interior of the cylinder so that the spring can push the piston with the pressure ram and the associated pressing jaws back into the rest position.
  • the reinforcing steel can then be pulled out of the device with the finished conical external thread.
  • the burr can simply be pressed into the pressed thread.
  • the reinforcing steel is rotated about its longitudinal axis between the press jaws retracted in the radial direction until each ridge running in the longitudinal direction and over the entire length of the thread is opposite the inner surface of a press jaw, after which the press jaws are pushed against one another again in the radial direction.
  • the device 50 drawn with dashed lines in FIG. 1 is advantageously used for this purpose.
  • This device consists of a guide ring 51, which is provided for pushing onto the reinforcing steel 46, and a stop pin 52, which protrudes from the front surface of the press head in the axis-parallel direction.
  • the guide ring has a guide surface 58 and a threaded hole 54 running in the radial direction, into which a wing screw 56 is screwed.
  • Fig. 3a shows schematically the axial section through a press jaw 60 with the threaded profile 61 corresponding to a conical nut piece.
  • the individual gears of this profile are aligned symmetrically to the longitudinal axis 62, i.e. each flank 63 and 64 encloses the same angle y or y "with the plane 66 lying transversely to the longitudinal axis.
  • the figure further shows that the two flanks of each gear have different lengths, the front flank during thread pressing in the axial direction of displacement 64 is longer than the rear flank 63. This different length of the flanks corresponds to a different surface size of the thread and thus a different pressure on the surface when pressing a thread.
  • press jaws whose passages are arranged symmetrically to the cone of the inner surface.
  • 3b shows the axial section through such a press jaw 70.
  • the threads of the thread have flanks 71, 72 which are aligned with a straight line 73 which is perpendicular to the cone 74 of the inner surface (or by the cone angle ⁇ the straight line 76, which is perpendicular to the longitudinal axis, is inclined) includes the same angle 8 'or 8 ".
  • the flanks of the individual threads are of equal length and therefore the pressure acting on the flank of each thread thread when pressing a thread is equal.
  • the piston 13 had a diameter of 140 mm and a stroke of 25 mm.
  • the device was connected to a hydraulic pump that generates a pressure of approximately 700 bar, which corresponds to a force per area on the piston of 900 kN.
  • the angle a of the surface lines of the conical interior 27 was 10 °. If the grooves in the inner cone are simply regarded as inclined planes with an inclination of 5: 1 for the deflection of the force generated by the hydraulic press from the axial to the radial direction, then the force of the press jaws acting in the radial direction is approximately 5000 kN.
  • the device was used to press a conical thread into a reinforcing steel of 40 mm diameter made of steel IIIA with a yield strength of 5000 kg / cm 2 within 5 seconds.
  • the thread showed only a small burr, which did not need to be cleaned and does not hinder the screwing on of a nut piece. No hairline cracks could be found in the area of the thread in the ground longitudinal section through the steel.
  • the described embodiment of the device is relatively light.
  • the weight of the press and press head is approximately 35 kg, which makes transportation and installation of the device to or at the place of work considerably easier.
  • the device described can be modified in many ways and adapted to special requirements.
  • the device described can be used not only for pressing conical threads into reinforcing steels, for example, but also for pressing such threads into any suitably prepared workpieces.
