Definitions

  • the invention relates to a device for the extrusion of profiles or the like. From a block or bolt stored in a receiver bore of a block receiver, in particular from a light metal bolt, by means of a moving ram through the shaping cross section of a die connected downstream of the block receiver on a die holder.
  • the invention also relates to a method for extrusion therefor.
  • a device of this type is known from DE-OS 26 51 564, in which it is described how the bolt is placed in front of the pick-up hole by means of a loading carriage and then inserted into it by the press ram. The back of the bolt lies on the die. It has proven to be disadvantageous in the known extrusion presses that at the end of the pressing process a so-called pressing residue always remains, which protrudes from the die like a disk and not only in must be removed in a complex manner but also represents a reduction in the press application.
  • the inventor has set himself the goal of designing a device and a method of the type mentioned at the outset in such a way that it is possible to carry out the extrusion without any remainder of the press.
  • a pre-recipient is arranged between the block receiver and the die with a compensation chamber which is coaxial with the receiver bore of the block receiver.
  • this compensation chamber is adapted approximately to the size of a conventional press rest and, at the end of the pressing process, takes up the press rest for a bolt until the next bolt is placed and takes this - temporarily present - press rest through the shaping cross section. Therefore, the method according to the invention is characterized in that the baling residue is generated in a compensation chamber connected downstream of the block receiver as an abutment for a subsequent block or bolt, the baling end face being in contact with the free end of the following block before a baling process.
  • the sensor bore of the block sensor is vented to allow a smooth transition between the two bolts mentioned.
  • the pre-recipient is designed to be movable relative to both the block receiver and the die, preferably to be connected axially and to be pulled out radially.
  • centering elements are provided on the pre-recipient, which interact with counter-elements in the block receiver or the matrix or the matrix holder.
  • Axially projecting centering ribs or centering pins are to serve as centering members, which engage in a centering groove of the machine part to be connected in each case.
  • the proposal according to the invention it is now possible to press out the bolt without leaving a pressing residue, thanks to the equalization and venting chamber according to the invention, the diameter of the pre-recipient normally corresponding to that of the sensor bore according to the invention.
  • the depth of the chamber is adapted to the previously usual residual thickness of about 40 to 50 mm.
  • the pre-recipient connects to the rear of the block transducer, which makes it possible to vent the transducer bore when loading the next ingot - if necessary, a venting stroke can take place within the scope of the invention.
  • the press ram is equipped with a press disk known per se, which preferably has a concave surface which is non-adherent to the press material; this shape, which is reflected in the remaining part of the remaining press material, makes it easier for the air to escape when the new bolt is pressed on or when it emerges.
  • the surface of the press disk must be treated, which is preferably done by means of nitriding, cooling, microsealing or by a ceramic coating.
  • a block pickup 3 with a bushing 4 axially penetrating pickup bore 5 for a block or bolt 6 made of aluminum can be recognized provided press ram 8 of the plunger 2 in press direction f x can be pressed through the sensor chamber 5.
  • peeling segments 11 are arranged which can be moved radially to the press axis A and which can be closed to form a peeling ring around the bolt 6, the cutting edge 12 of which peels off the contaminated block skin to form a chip ring 13.
  • the rear 15 of the sleeve 4 is followed by a pre-recipient 20 - in the selected exemplary embodiment - comprising recipient ring 21 and pre-sleeve 22 with this integrally formed centering rib 23, which upon axial displacement (arrow y) of the pre-recipient 20 into a ring-like centering groove 16 of the block sensor 3 or sleeve 4 is inserted or temporarily removed from it.
  • a chamber 24 In the center of the pre-recipient 20, a chamber 24 can be seen, the width i of which is slightly larger than the diameter d of the pick-up bore 5, specifically in adaptation to the width of a pressing residue that otherwise arises during extrusion - the same applies to the length e of the so-called compensation chamber 24 .
  • the pre-recipient 20 is followed in the pressing direction x by a partially ring-shaped tool carrier 30, in which - held by a stop rib 31 and support members 32 - a die 33 with a pressure plate 34 is supported.
  • the shaping cross section of the die 33 is designated 35.
  • the press rest front 40 shows the contour of the slightly concave press disk end 9.
  • a profile 41 produced from the bolt 6 a protrudes in the pressing direction x from the shaping cross section 35 of the die 33, through the central bores 36, 37 of the pressure plate 34 and the support member 32 beyond the head of the press.
  • the bolt 6 is compressed by the press disk 7, air still present in the pick-up bore 5 escaping through an axial vent bore 19 of the press ram 8 (FIG. 4).
  • the pick-up bore 5 is traversed by the press ram 8 until the press disk face 9 protrudes a little into the compensation chamber 24 of the pre-recipient 20.
  • the pressure plate 7 has, in particular according to FIG. 4.5, a concave pressure plate face 9, the center of which is surrounded by a front ring 42.
  • the latter is equipped with radial grooves 43, thanks to which the venting process described is simplified; Air present between the pin 6 and the wall of the receiving bore 5 - especially in the apex 5 s thereof - passes through the groove (s) 43 into the press disk center and from there into the vent hole 19.
  • air channels 44 run from the edge of a convex press disk face 9k to the axial vent hole 19.
  • These air channels 44 which are inclined to the press axis A, can be replaced by the use of a floating press disk insert which - after being relieved - lifts off slightly from the press disk base and then between and the pressure plate holder allows the air to the vent hole 19 (see at 50 in Fig. 4).
  • Both the concave press disk face 9 and the convex version 9 k are prepared by a nitriding process, by microsealing or the like so that the light metal to be pressed does not adhere to the press disk 7.
