Definitions

  • the invention relates to a rotary hammer machine with back connecting wedges for plunge hammering, the jaw closing wedges being arranged axially parallel, displaceable and exchangeable between the hammer plunger and the hammer jaws.
  • Rotary hammer machines which, by means of radially guided hammering tools, contribute to reducing the cross-section through oscillating hammer movements. serve as a rod or tube. The material is reduced in cross-section under feed.
  • the object of the invention is also to achieve a resetting of the hammer jaws in order to keep the hammer opening open even in the case of jaw locking wedges which can be displaced radially.
  • the hammer mechanism consists of the hammer shaft 1 with hammer plunger 2 and hammer jaws 3, which (3: form the hammer opening 4 for the workpiece 5.
  • the jaw locking wedges 6 can then be displaced axially parallel between the hammer jaws 3 and the plungers 2.
  • This is followed by the pressure rollers 7 with cage 8, which act on the heads 9 of the hammer jaws 2 when the shaft 1 rotates and which (7) run in the outer ring 10.
  • the outer ring 10 can rotate instead of the shaft 1 or both run (1 and 10) in the same direction at different speeds or also in opposite directions to each other This oscillating movement creates the oscillating hammer movement of the hammer plungers 2 with hammer jaws 3, which can be superimposed on the radial feed movement by means of the jaw closing wedges 6.
  • the jaw closing wedges 6 there are two, three and four jaw arrangements known.?
  • the hammer plungers 2 are kept open by means of springs 11 on the hammer heads 9 in the case of insufficient centrifugal force when the machine is running slowly or at a standstill.
  • the hammer plungers 2 and hammer jaws 3 have axially parallel bores 12, into which a spring clip 13 connecting both is inserted.
  • This spring clip 13 is bent on its spring arm 13a and 13b to be inserted in such a way that the support lies sufficiently far in the hammer plunger 2 and in the hammer jaw 3 to hold the same together resiliently.
  • the spring clip 13 is cranked sideways at 14, so that the jaw lock wedge 6 located between the hammer plunger 2 and the hammer jaws 3 can extend.
