Definitions

  • the invention relates to a device for rolling threads or the like. Profiles by means of two rolling tools rotating in the same direction, the distance between which can be changed, the rolling tools being arranged on corresponding displaceable guides for changing this distance from one another.
  • Thread rolling machines with a stationary rolling tool and a second rolling tool mounted in a slide are known. This slide is then moved hydraulically or mechanically in the direction of the stationary roller, thus rolling the profile into the workpiece. However, the workpiece is laterally displaced, so that a uniform penetration of both tools into the workpiece is not ensured.
  • the inventor has set himself the goal of developing a device of the type mentioned above, by means of which the distance between two rolling tools can be adjusted completely synchronously, without the need for a later new adjustment or alignment of the rolling tools.
  • both rolling tools or their guides are connected via a lever arrangement to a central lever which can be rotated about an axis by a drive.
  • This invention ensures on the one hand that the rolling tools are guided in exactly the same axial plane, i. H. both guides or corresponding guide slides run on the same axis. How these guides or guide slides are designed is irrelevant within the scope of the invention.
  • a conceivable solution is that the slides are guided in corresponding guide troughs which are molded into the machine housing.
  • rails can also be provided in the machine housing on which the guide slides run.
  • the central lever consists of two wings, each wing being connected to a lever arm by means of a cross member, and this arm is again connected to the corresponding guide slide assigned to it.
  • the invention is not intended to be limited to this lever arrangement, since other lever arrangements with levers interposed therebetween are also conceivable, for example.
  • the lever arm then has a pivot point fixed to the housing between the linkage to the crossmember and its connection to the guide carriage, about which point it rotates. If the crossbar presses on its articulation with the lever arm, it rotates around the pivot point and thereby moves the guide carriage along its guide. It will prove advisable that the lever arm is also articulated to the guide carriage, this articulated connection must allow a certain circular movement of the lever arm. For this purpose there are corresponding limiting or pressure plates in the guide carriage.
  • the crossbar according to the invention consists of two strips which strike the central lever on both sides of a wing. They are then articulated to the wing via a central bolt. The lever arrangement is thus stabilized.
  • the wings are formed in the rest of a sleeve, which in turn rotates in corresponding housing-fixed bearings.
  • a rotary bolt or the like can also be used here instead of a sleeve.
  • the sleeve has the advantage that a stub shaft of a gear can engage in its axial bore, which in turn is actuated by a corresponding drive.
  • This drive can be, for example, a double-acting linear cylinder or sealing piston cylinder.
  • the central lever is the starting point of every movement of the rolling tools, so that, for example, irregularities in the drive are transmitted completely evenly to the rolling tools and their guides. Absolute synchronism is guaranteed.
  • a device R for rolling threads or the like. Profiles has a machine housing 1 in which the essential mechanical elements are separated from corresponding switching or control elements by a base plate 2. In the position of use, a cover plate 3 also covers these mechanical elements, so that the machine housing 1 is essentially closed.
  • peripheral tools 4 and 5 are provided with corresponding thread profiles, not shown.
  • the rolling tools 4 and 5 are arranged on shafts 6, which rotate about corresponding axes 7 and 8, respectively.
  • the shafts 6 rest in a bearing block 9, which is fixed to a guide carriage 10.
  • This guide carriage 10 forms a projection 11 which is penetrated by the shaft 6 and in which there are further bearing shells, not shown, for this shaft 6.
  • Corresponding connecting flanges 12 are provided on this projection 11 for an articulated shaft 13, which connects the shaft 6 to a gear part 14.
  • a separate gear part 15 is also provided for the other shaft 6 of the rolling tool 4, both gear parts 14 and 15 being connected to one another via a coupling 16.
  • the corresponding geared motor 17 is then flanged onto the gear part 15.
  • Both guide carriages 10 are guided in a guide groove 18 in the base plate 2 and in a guide channel 19 in the cover plate 3 (see FIG. 2).
  • the guide carriages 10 can be adjusted in the direction x, the distance a between the two rolling tools 4 and 5 being adjustable.
  • This adjustment of the distance a between the two rolling tools 4 and 5 or the displacement of the guide carriage 10 in the direction x takes place via a lever arrangement 20.
  • the core of this lever arrangement is a central lever 21 which, as shown in particular in FIG. 3, about an axis A. turns.
  • This central lever 21 consists essentially of a sleeve 22 with an axial bore 23.
  • wings 24 are formed on both sides.
  • the sleeve 22 engages in a trough 25 in the base plate 2 and rotates there, supported by corresponding bearings 26, about a bearing pin 27.
  • the sleeve 22 partially penetrates the cover plate 3 and is supported against the edge 28 of a corresponding opening in the cover plate 3 via a further bearing 29.
  • a shaft stub 30 engages in the axial bore 23 from above, which can be rotated about the axis A by a drive 32 via a corresponding gear 31.
  • This drive 32 can be, for example, a double-acting linear cylinder.
  • the vanes 24 are penetrated by central bolts 33, which rotate in corresponding slide bearings 34. With these central bolts 33, two strips 35 and 36 of a cross member 37 are connected to the wings 24 from the outside.
  • this cross member 37 has an articulated connection via a pivot pin 38 to a lever arm 39 which has a pivot point 40 fixed to the housing.
  • the lever arm 39 engages in the guide carriage 10 or a corresponding recess 41 in the guide carriage 10 and is articulated there to the guide carriage 10 via a bolt 42.
  • the narrower region of the recess 41 around the bolt 42 is formed on the one hand by a limiting plate 43 and on the other hand by a pressure plate 44.
  • a further pressure plate 45 can also be assigned to the lever arm 39 in order to absorb the pressure.
  • the two rolling tools 4 and 5 are set in rotation about their axes 7 and 8 via the geared motor 17, the gear parts 14 and 15, the cardan shafts 13 and the shafts 6. This rotation runs in opposite directions.
  • a workpiece for example a rod section, is then inserted into the distance a between the two rolling tools 4 and 5, and the corresponding thread profile is given via the corresponding peripheral profile of the rolling tools 4 and 5.
  • the central lever 21 is set in motion via the drive 32 and the gear 31, wherein it rotates about its axis A.
  • the present arrangement according to the invention is not only limited to the horizontal arrangement of the two rolling tools with respect to one another, but it can also function in the case of a vertical or oblique arrangement. There is no difference in the very positive effect.
