Definitions

  • the invention relates to a jaw locking device according to the preamble of claim 1 and is based on one of the designs known from DE-A-2 806 380.
  • the locking lever is actuated by a corresponding control cam depending on the position of the drawing slide.
  • the actuation is carried out by means of a hydraulic mechanism attached to the slide itself. cylinder, so that there is a constant contact of the locking device with the jaw actuators.
  • this constant contact with the drive, namely the corresponding control cam is not provided. If the movements are not carefully coordinated, it can happen that the jaw locking lever hits the cam disc more or less gently.
  • a constant contact of the jaw locking lever with the control cam disc is achieved by the invention.
  • the preloaded buffer additionally ensures that the jaw locking device also acts on the opening process if necessary.
  • the device shown in the figures represents a continuous drawing machine with two drawing carriages 1, 2, which run in a stationary slideway 5 parallel to the drawing direction, i. H. are guided parallel to a pipe 3 to be drawn. It also contains a drawing ring 4 and a starting device 7.
  • the machine frame of the drawing machine is designated by 6.
  • a drive cam 13 is attached to a drive shaft 12 and a counter cam 14 is offset by 180 °.
  • the drive cam 13 causes two-armed drive levers 8, 9 to drive the drawing carriages 1, 2, with which the arms 8a and 9a are connected via links 32 and 33.
  • the shorter arm 8b of the drive lever 8 lies against the drive cam 13 via a roller 9 and the shorter arm 9b of the drive lever 9 via a corresponding roller.
  • Another lever system 34 and 39 which is elastic via springs 36 and 38, is in contact with the counter-cam plate 14 via further rollers 35 and 37 and ensures that the drive cam levers 8 and 9 are in constant contact with the drive cam plate 13 as well as for the return of the drawing slide 1 and 2nd
  • the drive levers 8 and 9 are pivotable about fixed axes 10 and 11. On these fixed axles 10 and 11, control cams 17 and 18 are rotatably supported and driven by gears 19 and 20, which mesh with a drive gear 21 seated on the drive shaft 12. Arrows that are not labeled indicate the direction of rotation.
  • a bolt 30 or 31 is fastened, about which a three-armed jaw locking lever 15 or 16 can be pivoted.
  • An arm 15a or 16a of the jaw locking lever 15 or 16 is connected via a suitable link 26 or 27 to a jaw actuating element 24 or 25 which is movably guided in the drawing slide 1 or 2.
  • Another arm 15b or 16b of the jaw locking lever 15 or 16 has contact with the control cam disk 17 or 18 via rollers 28a or 28b and is constantly pressed against the drive cam disk 17 or 18 via a hydraulically preloaded buffer 22 or 23.
  • the buffer 22 or 23 is clamped between the shorter lever 8b or 9b and a further arm 15c or 16c of the jaw locking lever 15 or 16.
