STAMPING PRESS Filed Sept. 27, 1966 2 Sheets-Sheet 1 K. H. STEIN ST'AMPING PRESS July 9, 1968 2 Sheets-Shee 2 Filed Sept. 27, 1966 United States Patent STAMPING PRESS Karl H. Stein, Friedrichstrasse 39, Pirmasens, Germany Filed Sept. 27, 1966, Ser. No. 582,400 Claims priority, application Germany, Oct. 16, 1965, M 53,000 Claims. (Cl. 83-103) This invention relates to a stamping press having a stamping table which can be moved underneath a stamping die and which is adapted to receive sheets or stacked material to be stamped, whereby several identical or different patterns can be stamped out of one sheet or a stack of sheets. The invention is applicable to all kinds of stamping presses, large area presses as well as automatic presses, automatic bridge dish stamping presses and envelope tamping presses.
As is known, when parts are stamped out of a ge stacks of material, the stack placed on the table of the bridge stamping press or the automatic bridge dish stamping press is manually push down against the table after stamping, or the stampings and the waste are taken off the table directly. In any event, the removal of the stampings from the stack is cumbersome.
An object of the invention is to overcome the problem of pushing the stamped out stack down from the stamping table mechanically and of removing the stampings from the stack or from the waste mechanically.
According to the invention there is provided a depositing table associated with the stamping table and a shifting device to shift the stamped material from the stamping table to the depositing table, the depositing table being provided with a plurality of openings and with pusher members which extend through the openings, the pusher members being attached to a plate which is vertically displaceable below the depositing table. The shifting device is preferably comprised of a cylinder having a piston rod which carries a rake. A lifting device for the displaceable plate is disposed at the underframe of the depositing table.
The cylinder can be replaced by other suitable devices, such as electric motors, chains, and cams, and similar means can be used to operate the lifting device.
The pusher members are preferably detachably connected to the displaceable plate to enable the pusher members to be fitted into various holes depending on the pattern of the stampings.
Preferably the pusher members are eccentrically disposed relative to the associated stampings to cause the stampings to be tilted in the stack with their edges located above the surface of the top sheet of material to facilitate the removal of the stampings from the waste.
The invention will now be described in greater detail with reference to the attached drawing, wherein:
FIGURE 1 is a front view of the machine according to the invention;
FIGURE 2 a top view thereof; and
FIGURE 3 a front view corresponding to FIG. 1 in a different working position.
In the drawing there is shown a stamping press 1 which has a movable table 2 on which a stack of material 3 to be stamped is deposited manually. Stops can be provided on table 2 for accurate positioning of the material. Table 2 is movable to a position beneath press 1 either by hand or automatically by a motor or other suitable driving means. Single packets or stampings 4 are then stamped out of the stack 3 of material which for purposes of discussion will be assumed to be paper. For this operation, a stamping die 17 is moved to various operative positions, one of which is designated as 17a. 17b is the stamping punch. The stamped-out parts 4 remain in the waste 5.
As a rule, the waste is of frame or grid form. The table 2 is now removed from beneath the press 1.
Adjacent press 1 is a cylinder 6, actuated through suitable control elements by a pressure medium such as compressed air or oil.
The front end of a piston rod 7 of cylinder 6 carries a rake 8 whose width corresponds approximately to that of the paper stack 3.
Adjacent the side of table 2 which is opposite cylinder 6, is a depositing table 16. This depositing table 16 has a plurality of holes 15 in a plate 9 thereof, corresponding to the configuration of the possible stamping patterns.
Fingers or pusher members 10 are inserted into selected of the holes 15. The holes 15 with fingers therein are shown in black in FIG. 2. The lower ends of fingers 10 are supported on a plate 11 which, in turn is attached to a piston rod 12 of a lifting cylinder 13. The fingers 10 may be constituted of bolts which are threadably engaged in plate 11.
The stampings 4 are now positioned above fingers 10. The lifting cylinder 13 is actuated automatically or by hand, and plate 11 lifts fingers 10 attached thereto. The fingers 10 are eccentrically displaced relative to stampings 4 by virtue of the position of the stampings On the table 9 and the stroke of piston rod 12 is so adjusted that at least one end of the stampings 4 is lifted a sufiicient height as to protrude above the Waste, as seen in FIG. 3, and thereby readily be removable by hand. In FIG. 3 can be seen the oblique position of the stampings result ing from the eccentric position of the fingers. If desired, a hold-down device or the like for the waste can be provided.
The upper ends of fingers 10 can also be provided with plates which can enable lifting of the stampings 4 parallel to depositing table 16. Piston rod 7 can be retracted irnmediately after its extension. Fingers 10 are lowered after removal of the stampings 4, and depositing table 16 can then be cleared of waste 5.
By rearranging the fingers 10 in other holes 15 of depositing table 9, any shapes can be arranged as desired and stamped out.
It is within the contemplation of the invention to replace piston rod 7 by a motor driven rack. A spindle, driven by a motor via a nut, could also be used in place of piston rod 7 or 12.
The invention results in a substantial saving in Working time when stamping individual sheets or stacks of material such as paper, plastics, rubber, textiles, or the like.
Numerous modifications and variations of the invention will now become apparent to those skilled in the art without departing from the scope and spirit of the invention if defined by the attached claims.
