Definitions

  • the invention relates to a coin stamping press with a drive for plunger and die, an ejector die against which the die can be pressed with the interposition of the blank and to which part can be yielded, a drive for the ejector movement of the ejector die and a device for feeding the die and for removing it of the finished part.
  • a coin stamping press is known with a force element acting on the stamp, a feed device for the stamping blank to a stamping tool, where it comes to the intermediate layer between a stamp and an ejector stamp, and a discharge device for the finished part.
  • the embossing drive includes a toggle lever mechanism with a rotating eccentric shaft, connecting rod and two toggle levers articulated by it.
  • the toggle levers are supported on articulated bolts on a part on the frame and, when the eccentric shaft moves, drive the plunger and with it the stamping die.
  • the ejector die is constantly under a force opposing the ram movement by means of a pneumatic member connected via deflection means.
  • a toggle press has been described with a drive of the type described above for a vertically movable press frame.
  • the press table-side ejector has a two-armed lever, one end part of which is guided with an ejector rod in the press table and die and the other end part is guided by a pressure cylinder against a rotating cam.
  • the ejector rod, which is guided in the press frame, the press ram, interacts with a two-armed angle lever, which can be moved along with the press frame and with the end part remote from the ejector rod is placed against a press-fixed curve by means of pressure cylinders.
  • a motor-driven crankshaft 3 is rotatably mounted for driving the central bearing 4 of a push rod 5, designed in the manner of a triangular lever.
  • a push rod 5 designed in the manner of a triangular lever.
  • the front rocker bearing 6 is articulated via a push rod 11 on the tappet 12 at the pivot point 19.
  • the plunger 12 is in the direction of pressure, which is longitudinally displaceably mounted in the punch center line 15 in the frame and carries the die 16 at its end part opposite the pivot 19 the embossing tool is oriented.
  • the embossing piece 13 can be guided, for example, via a feed plate 18 in front of the embossing tool and can be led out of this area after the embossing.
  • the feed plate is drivable at 44 and is adjustably supported by a stepping device.
  • the step drive can also be done from the press drive.
  • the feed plate is pivoted out of the stamping area.
  • the means for feeding the embossing blank into the feed plate, the means for the gradual movement and for the removal or ejection from the turntable are not shown in detail and can be constructed in a known manner.
  • Position 27 indicates the position of the embossing piece 13 and the embossing surfaces of the embossing die 16 and the ejector embossing die 17.
  • the latter interacts with an ejector rod 31 which can be actuated via a deflection drive in the direction of an ejector movement guided in the punch center line 15.
  • 4 comprises, among other things, a first double-armed reversing lever 20, which is mounted fixed to the frame in the pivot point 22.
  • the deflection lever is articulated at 24 on the tappet 12 and can thus be moved with it.
  • Its second lever end carries a swivel joint 32 in which a push rod 26 is rotatably mounted.
  • the fulcrums 22, 24 and 32 are located on a central axis 29 common to them.
  • the frame-side fulcrum 22 is arranged perpendicular to the stroke movement direction of the plunger 12 along its half stroke length.
  • a second double-armed bell crank 21 is mounted so that it can swing.
  • This has a long groove in which a sliding block 37 is longitudinally movable and via a spindle drive 34, for. B. in position 37, is adjustable.
  • the bell crank is cranked to receive a fork 36, which carries a role to form an output fulcrum 33. This rests on the end 28 of the ejector rod 31 and is adjustable via a longitudinal adjustment drive 35 for the fork so that the output fulcrum is centered on by the pivoting movement the deflection 21 caused deflection is adjustable.
  • FIGS. 2 and 3 show in particular the phases of the manufacture of the stamped part as a function of the rotary movement of the central bearing 4.
  • the frame-side link bearing 9 is arranged with respect to the punch center line 15 on the side opposite the crankshaft 3.
  • the link 8 is movable with the connected rear swing arm bearing 7 around the link bearing 9 in a circular arc with the radius dimension corresponding to the length of the link.
  • the distance from the center of the rear rocker bearing 7 to the center of the center bearing 4 is greater than the maximum possible distance from the center of the center bearing 4 to the punch center line 15, measured as the distance between the center of the center bearing 4 and the center of the rear rocker bearing 7.
  • the distance from the center of the front Swing arm bearing 6 to the middle of the rear swing arm bearing 7 and the distance from the center of the front swing arm bearing 6 to the center of the central bearing 4 is designed such that the center of the front swing arm bearing 6 whenever the central bearing 4 assumes a position that corresponds to the front dead center T v of the tappet 12, on the side to the punch center line 15, which is to be assigned to the frame-side link bearing 9.
  • the center bearing 4 is in a position which corresponds to the rear dead center T h of the tappet 12, the center of the front rocker bearing 6 lies on the side of the punch center line 15 which is to be assigned to the crankshaft 3.
  • the finished embossed part for example a coin or medal
  • the takeover of the coin into the feed plate 18 takes place here in a period of greatly slowing movement of the plunger up to approximately the point 42 shown.
  • the front rocker bearing 6 articulated via the push rod 11 on the plunger 12 is thus via a closed path, curve 43, below
  • Driving the plunger can be driven and the ejector stamp 17 can be carried along at least for the area of the return movement of the plunger via the deflection gear in the sense of an ejector movement, so that even after the embossing the finished part by the stamp 16 and the ejector stamp 17 and between them up to Passing to the feed plate 18 is performed on all sides, possibly including a minor game.
  • the deflection lever 21 which is placed on the end 28 of the ejector stamp and is embodied as shown in FIG. 4, is acted upon by a push rod 45, which is articulated via a fulcrum 46 on a control lever 50.
  • the control lever can be pivoted about a fulcrum 51 and is placed against the control cam 52 by means of a force accumulator (not shown) by means of a control roller 47, which has curve components 53 for adjusting the push rod.
  • the control cam is mounted in a rotating manner and moved by a drive pulley 48 which is connected to the tappet drive via a belt drive 49.
  • the adjustment of the cam disc 52 leads to an ejector movement of the ejector tappet in synchronism with the tappet return movement in the sense of the description in FIG. 4.
