Definitions

  • a Kopfstauchvorraum for elongated workpieces, such as rods, tubes, wire or the like.
  • the clamping device comprises a housing with a hydraulically in Axial direction of the workpiece from a starting position into a clamping position (and vice versa) displaceable sliding body, are inserted into the at least two evenly around the workpiece ordered clamping segments which rest on its side facing the stamper against an inserted into the housing and there fixable locking plate can be moved radially against the workpiece by a displacement of the sliding body in its clamping position and each record at least one jaw which is pressed radially against the workpiece to its jamming by the clamping element which supports it t, further wherein the upsetting punch on the extension side carries a forming tool for compressing the workpiece, with which it can be pressed during extension through an opening provided in the locking plate
  • the head compression device according to the invention also builds relatively space-saving due to the arrangement of the individual parts of the clamping device inside the housing, wherein in the invention, the axial process of the sliding body formed into a radial clamping movement of the clamping segments and thereby an arrangement of the latter space-saving within the sliding body is possible.
  • the housing is provided on its front side opposite the locking plate front with a lid having a central opening through which the workpiece can be inserted into the housing, wherein the sliding body in its initial position with a stop surface attached to it against this cover rests.
  • a guide and centering device for the workpiece is preferably mounted on the side facing away from the housing of the lid.
  • the upsetting unit 2 sits on the frame 4 on two parallel longitudinal rails 7, along which they can be moved by a motor 8 and a spindle drive 9 again in the direction of a.
  • This additional compared to conventional devices traverse axis allows a great deal of flexibility in using the compression unit 2.
  • the workpiece can thus be positioned in a specific position in front of the upsetting unit 2 driven back on the longitudinal rails 7, this then being moved forward, the workpiece up and then again can go back.
  • the supply of workpieces by a transversely to the axial direction of the workpieces moving feeder (such as a rotating robot with circular mounted around these processing units, or a moving feeder with several parallel processing stations mounted o. ⁇ .).
  • Fig. 3 shows the compression unit 2 in a vertical section (perpendicular to the bottom plate 5) along the longitudinal center axis 21 of the compression unit 2. Shown here is the open position of the guiding and centering unit 12, ie the position in which workpieces 20 can be introduced. In contrast, shows Fig. 4 3 a horizontal section of the compression unit 2, wherein the sectional plane is parallel to the base plate 5 and through the longitudinal central axis 21 (FIG. Fig. 2 ) of the upsetting unit 2 extends. In Fig. 4 is now the closed position of the tools, so the compression position shown.
  • a bore 29 is further attached, by means of which a pressure connection 43 (cf. Fig. 5 ) Pressure fluid for axial displacement of the sliding body in the housing 10 can be introduced.
  • each jaw 32 and 33 fitted on guides 34 and then inserted into a corresponding receiving groove of the clamping element 28.
  • the length of this receiving groove is slightly larger than the total length of the jaws 32 and 33 together. This results in that after complete insertion of the front jaw 32 between this and the other jaws 33, an axial spacing A remains.
  • the second jaw 33 is prevented by means of a retaining strip 35 axially slipping out of the receiving groove.
  • the jaws 32 and 33 are designed so that they can be used on both sides, d. H. if you take them out of the receiving groove of a clamping segment 28 and rotates 180 ° about its longitudinal axis, they can then be used equally at the other clamping segment 28. This can be achieved that with a jaws 32 and 33 either achieved a double life or different workpiece diameter can be edited.
  • the compression module 2 may also be additionally equipped with a lubrication system, which prevents the risk of "eating” on the tools, which is not shown in the figures.
