Definitions

  • the invention relates to a device for the rearrangement of intermediate products for intermediate treatments in horizontal presses, in particular multi-stage presses, in the frame of which matrices are arranged in a block for successive treatment processes and in the press bar stamps for inserting the intermediate products into the matrices and for shaping them, which are arranged side by side Device with spring-loaded collets for gripping and transferring the intermediate products after a completed treatment process into the position opposite the next die in which the subsequent treatment process is to be carried out, the collets also being arranged next to one another.
  • Relocation devices used in horizontal multi-stage presses in which the collets are opened mechanically so as not to stand in the way of the punch when the intermediate product is inserted into the die or in which the collets are lifted by a holder outside the area of the punch in a direction perpendicular to the die axis , are known.
  • the actual rearrangement movement becomes linear - which is most advantageous - in others along a semicircular path in a direction perpendicular to the die axes Level executed.
  • the collets are moved along an arcuate path in a plane containing the die axes.
  • the present invention is intended to eliminate the above disadvantages of the known devices and it is an object of the invention to provide a device provided with spring-loaded collets which is insensitive to contamination and therefore works perfectly with a simple construction.
  • a holder of the collets is attached to a support tube tapering at an angle to the axes of the dies, the one hand from the one die zu'der other die and again back along its axis for the displacement of the grippers back and forth, on the other hand about its axis for lifting of the clamping jaws in a position outside the path of the punches in the working movement of the P RESS bears and above the level of the dies when the dies are changed and when the collets return down to the lower position for gripping the intermediate product, the support tube being arranged in the block receiving the die and in a gear box so as to be displaceable and rotatable.
  • the entire drive can be carried out in one .
  • sealed box can be arranged next to the press work space, the surface of the support tube can be protected against aggressive media in the press work space with the help of known chemical and metallurgical treatment processes.
  • the bearings of the support tube in the die block can be sealed well against the ingress of contaminants.
  • a block 2 is attached to the frame 1 of the press, in which dies 3 are mounted.
  • Spring-loaded collets 4 arranged on an interchangeable plate 28 are held by a holder 5 which is placed on vertical guide surfaces 7 with its two arms. These guide surfaces 7 are provided on both sides of the block 2 of the matrices on a support tube 6.
  • a margin is provided between the positions. len, where the holder 5 is attached to the support tube 6 and the block 2 of the dies 3, a margin is provided. This margin is necessary for an axial displacement of the support tube 6 - which will be described in detail later.
  • the support tube 6 is mounted in the block 2 of the matrices 3 and in the wall of a gear box 29 so as to be displaceable and pivotable.
  • the corresponding bearings are sealed with sealing rings 27.
  • the support tube 6 At its end projecting into the interior of the gearbox 29, the support tube 6 is provided with a sleeve 21, into which a connecting tube 24 projects at one end.
  • the coupling of both pipes 6, 24 takes place by means of a spring-loaded catch 22, which is pressed into a notch 23 on the surface of the connecting pipe 24. In the position shown in FIG. 1, the spring-loaded catch 22 is connected to an end contact 26 of the electrical control of the press.
  • the second end of the connecting pipe 24 is provided with a pin 25 and by means of tie rods 8 (see also Fig. 2) connected to a one-armed lever 9 carrying a orschubkurvenis against a V 10 resiliently compressed feed roller 11. Due to the mechanism described, the support tube 6 is advanced along its axis.
  • a cross arm 12 (see also FIGS. 3 and 5), which rests with its free end on a horizontal lifting plate 13.
  • the lifting plate 13 is actuated by a lifting cam disk 16 by means of a two-armed toggle lever 14, the upper arm of which represents one arm of the pair of supporting arms supporting the lifting plate 13, while its lower arm carries a lifting roller 15 pressed against the surface of the lifting cam disk 16 by a tension spring 17.
  • the holder 5 is in contact with a swivel arm 18. This is coupled to the piston rod of a double-acting pneumatic cylinder 19 held on the frame 1 of the press.
  • the upper, i.e. free end of the swivel arm 18 projects into the interior of a profiled cover strip 20 which is provided on the top of the holder 5.
  • the press bear has removed itself from the frame 1 together with the stamps after the shaping has ended.
  • the lifting cam 16 By turning the lifting cam 16, the lifting plate 13 lowers and releases the cross arm 12.
  • the swivel arm 18 reaches its lower edge position (FIG. 4), in which it presses the holder 5 downward so that the collets 4 from the upper position, not shown, into their vertical position 1 and 4 corresponding lower layer return.
  • the collets 4 are again ready for gripping the intermediate products to be ejected from the dies 3, whereupon the work cycle described above is repeated.
  • the collets 4 are raised to the right by the action of the double-acting pneumatic cylinder 19 in the position above the level of the dies 3 according to FIG. 4.
  • the clockwise pivoting swivel arm 18 comes into engagement at its end with the profiled cover strip 20, so that the holder 5 together with the collets 4 is tilted upward about the axis of the correspondingly rotated support tube 6.
  • the transmission device is overloaded - i.e. if an inhibition of the axial or rotary movement of the support tube 6 occurs - the spring-loaded catch comes out of engagement with the notch 23 in the connecting tube 24, so that the transmission mechanism is not at risk of damage, since this connecting tube 24 is then freely movable inside the supporting tube-6 becomes.
