Definitions

  • PUNCH AND DIE RETAINERS The invention has particular relation to improvements in retainers for punch and die units and will be so described, though not so limited.
  • it features a uniquely advantageous triangular configuration and a specially formed centering plug.
  • the plug has the added and most important capability of serving as a simple but effective medium for backing critically positioned punch and die components.
  • the invention concepts enable a simplified and more efficient punch or die installation characterized by ease of handling and economy and efficiency in use.
  • the cutting or blanking components of die assemblies may be quickly and precisely positioned and with a minimum of effort.
  • the retainers may be quickly and readily removed and replaced without altering the precisely referenced position of the related punch or die element.
  • the normal procedure in setting up a die assembly is first to set up the lower die plate on the lower die shoe so as to properly orient the contained die button.
  • the punch to be coaxially aligned with this die button is then inserted in its retainer and centered in respect to the opening in the die button.
  • the retainer which has at least two passages for dowel-type locator pins to be inserted in the upper die shoe is then applied to the upper die shoe with a backup plate interposed between.
  • the backup plate has relatively enlarged openings therein for passage therethrough of the locator pins.
  • the present invention obviates the above problems, insuring a simpler, a firmer and a more precise installation which enables removal and replacement ofa retainer without fear of displacement of the respective axes of the related punch and die components of an installation.
  • the invention thus insures more effective die cutting operations with considerably less malfunction potential and correspondingly a maximum work output from a minimum of material.
  • Another object of the invention is. to provide a unique plug element for punch and die assemblies serving both as a precise positioning device and a force-dissipating backup medium.
  • a further object of the invention is to provide a punch assembly which obviates the need for a backup plate.
  • An additional object of the invention is to provide punch and die assemblies which may be readily interchanged without affecting the precise positioning of the: related punch or die components.
  • Another object of the invention is to provide punch and die installations with unique means for their precise reference.
  • a further object of the invention is to provide an improved retainer for punch, die and like elements having a configuration rendering it more'versatile in use and application.
  • FIG. 1 illustrates a fragment of a punch assembly embodyingthe concepts of the present invention
  • FIG. 2 illustrates the related die assembly in fragmentary form, which die assembly embodies the invention concepts
  • FIGS. 3 and 4 are fragmentary views referenced to the structure of FIG. 1 illustrating how the invention concept facilitates the transfer of holes from a punch retainer to the related die shoe;
  • FIGS. 5 and 6 illustrate the unique punch retainer in accordance with the invention in both plan and elevation and with the centering and force dissipating plug removed.
  • FIGS. 5 and 6 show a punch retainer 10 which in plan view has the unique form of a isosceles triangle the corners of which are arcuately rounded. Its apex is identified as 11 and its base corners as 12.
  • the retainer body is relatively thick in depth between its upper and lower surfaces 13 and 14 which are respectively parallel.
  • the retainer 10 has a cylindrical through passage 15, perpendicular to its surfaces 13 and 14 and, while not necessarily so, in the example shown, concentric to its apex 11.
  • One end portion 16 of the passage is conically expanded.
  • the expanded portion is relatively short in length and has its maximum cross-sectional area at the surface 13.
  • the retainer 10 has two additional through passages 17, both of stepped cylindrical form, which are paralleled to and triangularly and symmetrically positioned in respect to the through passage 15.
  • the single step in each passage 17 produces a shoulder 18 adjacent to and facing outwardly of the parallel surface 14.
  • the passages 17 provide for application therethrough of capscrews for mount of the retainer body 10 to a die shoe in a manner to be further described.
  • the retainer 10 has a further passage 19.
  • the passage is relatively inclined. It opens at one end from the surface 13 and at one side of its other end to the passage 15, adjacent but spaced from the surface 14.
  • the retainer 10 is installed with its surface 13 fixed in contacting and coextensive abutting relation to an upper die shoe 20.
  • a ball-type lock element 21 contained in the innermost end of the passage 19 is a ball-type lock element 21. This is biased inwardly of the passage 15 by a coil spring 22. The latter is contained within the passage 19 which is capped by the die shoe 20.
  • the ball 21 is so biased to wedge in an arcuate pocket or groove formed in one side of the head 23 of a round punch 24 inserted in the lower end of the passage 15. As described, the ball 21 locks the punch 24 to depend in projected relation to the body of the retainer 10.
  • the plug is an integral structure but it has two distinct portions.
  • the outer periphery of its inner portion 27 has a cylindrical configuration while the outer periphery of its outer portion 28 is conical.
  • the portion 27 is inserted to abut and back the head of the punch and is so formed to frictionally but releasably fit in the uppermost portion of the passage 15, to the point of its conical expansion at 16.
  • the upper or outer plug portion 28 is cut back immediately adjacent the upper end of the portion 27 and then conically expanded. Particular note must be taken of the fact that the outer peripheral surface of the portion 28 disposes concentric to and in a generally spaced parallel relation to the adjacent conically expanded surface portion 16 of the wall defining the passage 15.
  • the depth of the plug 26 is such that it is set inwardly 0f the retainer surface 13 to have one end define an abutted reference surface for the punch and its other expanded end lie in flush abutment to the die shoe 20, with the surface 13.
  • the plug 26 is tubular in nature, having a through passage 29 which is slightly larger in diameter than the cylindrical recess 30 formed in the die shoe 20in a manner to be further described. Tightly fit in the passage 29, generally coextensive therewith, is the expanded end of a pin 31.
  • pin 31 has a slip fit to fix it in the passage 30 of the die shoe 20.
  • the pin 31, through the medium of the plug 26, constitutes a single centering pin for the punch 24 and the retainer body 10.
  • the plug 26 not only serves a centering function but provides .a force dissipating medium for accommodating and disseminating the stress and shock incident to a repeated operation of the punch 24.
  • Capscrews are projected through the retainer passages I? to engage in the die shoe 20.
  • the shoulders 18 provide limiting surfaces for the heads of the screws.
  • the retainer unit can be readily replaced by a similar unit.
  • the retainer assembly and the press fit pin 31 can be pulled from the shoe asan integrated unit.
  • the pin 31 stays with the retainer, in the preferred embodiment illustrated, due to the nature of its press fit in the plug 26.
  • a similar retainer unit can be quickly applied in an obvious manner. Having received thereon a pin 31 it can be fixed to the die shoe as described.rThe pin 31 and the plug 26 again precisely define the same punch location with no requirement for adjustment or manipulation. Passages 17 for the screws are not and need not be critically dimensioned.
  • the retainer unit may be pulled from its plug 26 which may be left to per se provide a precision reference for slip fit of a new retainer unit as described, absent its plug.
  • FIG. 2 of the drawings shows the inventive plug concept applied in a slightly different form.
  • the inventive plug concept applied in a slightly different form.
  • it is embodied in respect to the assembly ofa die button to a lower die shoe and for use in an operative relation to the punch 2324.
  • a retainer 10 fixed on the lower die shoe 32 is a retainer 10.
  • the latter is similar to the retainer 10in all respects and like parts are identified by like numbers. Since the retainer 10' has an identical configuration and passages, the details thereof need not be further described except in reference to the improvements.
  • the body of retainer 10 is inverted so its surface 13 abuts the lower die shoe 32.
  • a tubular die button 33 Inserted in the end of the passage 15' remote from the surface 13 is a tubular die button 33.
  • the side of this die button is provided with an arcuate pocket or groove 25 to accommodate the wedging therein of the ball-type lock element 21' which is backed in the passage 19' by a coil spring 22'.
  • die button 33 is locked to the retainer 10 in the manner that the punch 2324 is locked in the retainer 10.
  • the die button is backed by one end portion 36 of a tubular plug 35.
  • the plug portion 36 is formed to have a releasable friction fit in the passage 15' in the space therein between the die button which it abuts and the conically expanded portion of the passage which opens to its maximum cross-sectional area at the die shoe 32.
  • a plug portion 37 the outer peripheral surface of which is conically expanded. From plug portion 36 the outer surface ofthe plug 35 is first cut back and then conically expanded to provide a conically formed solid skirt in adjacent but spaced parallel relation to the conically expanding surface portion 16 of the passage 15.
  • the conical skirton the outer surface of the plug provides a shoulder which abuts the adjacent surface of the die shoe 32 about an opening therein which receives a tubular extension 38 of the plug 35.
  • the outer diameter of the portion 38 is relatively reduced in respect to that of the plug portion 36.
  • the portion 38 has a tight but releasable fit in the passage 39 provided therefor in the die shoe 32.
  • the plug 35 can be applied to the retainer so the conical portion 37 thereof is spaced from the conically expanded surface of the passage Under such circumstances the base of the conically expanded peripheral portion 37 will lie flush with the surface 13 of the retainer body 10'.
  • the station for the die button can be readily located as to its center on the uppermost surface of the die shoe 32 whereupon the passage 39 may be drilled.
  • the retainer 10 including the plug 35 can be precisely applied through the medium of the tubular extension 38 on the plug.
  • the extension 38 is inserted in the passage 39 to have a relatively tight but releasable friction fit to the wall of the passage. This establishes the passage 15' in a precise orientation required for the particular work station.
  • the die button 33 On insertion of the die button 33 it will be precisely positioned and backed in a stable relation in such position by the end of the plug portion 36.
  • the inner diameter of the plug 35 is slightly greater than that of the die button to provide clear passage of blanks that might be punched and projected through the die button.
  • the retainer 10' may be quickly and readily applied to the lower die shoe by means of a ready insertion of the plug 35 in the die shoe which immediately defines the required position for the die button.
  • the passages 17 of the retainer which are illustrated in FIGS. 5 and 6 are not critically related to the position of the retainer and the passages may be simply and quickly transferred to the die shoe and capscrews applied in a manner believed obvious. Accordingly, there is only required a single positioning as defined by a single plug unit such as 35. The installation of the retainer 10' and the precise positioning of the die button 33 is speedily and precisely effected. Turning now to the retainer 10 as applied to the upper die shoe 20, the punch 24 is first inserted and locked in the retainer body 10 and brought down to position precisely and coaxially in reference to the die button 33.
  • the retainer 10 With the punch 24 so positioned the retainer 10 can be quickly clamped directly to the upper die shoe 20 which has already been positioned for use in the requireddie set. This is only possible because there is only a single locating device for the punch 24 and there are no critical aspects of positioning the passages 17 for the captype holddown screws. It is contemplated at this point that the plug 26 is inserted in the passage 15 as shown in FIG. 1 as an abutting backup device for the punch 24. With the retainer body 10 then clamped in place, reference is made to FIG. 3 of the drawings for the procedure whereby the passage 29 in the plug 24 may be directly transferred to the upper die shoe.
  • FIG. 4 of the drawings illustrates the alternative use in transferring the plug bore 29 to the shoe 20 of a drill bushing.
  • a firmly backed drill bushing through the medium of the plug 26 and the transfer of the plug bore may be effected with a precision balanced condition of the drill 40.
  • the bushing also conducts the drilled chips clear of the retainer. Whether the procedure of FIG. 3 or FIG. 4 of the drawings is used is optional and would depend on the particular circumstances.
  • the shock of impact and vibration attendant a punching process will flow in a direct axial line and due to the spacing between the conically expanded portion of the plug and the adjacent wall structure of the retainer there is a directed path for the shock effects.
  • the shock instead of being disseminated into the retainer body .with attendant problems of fatigue and deterioration of components is instead dissipated in the die shoe which has a much greater capacity to accommodate the same.
  • the unit force transmitted from one end of the plug to the other is substantially diminished due to the configuration of the surfaces which abut.
  • the plug will similarly serve to disseminate and dissipate the shock of punch operation, whether in respect to the punch or the die, so as to preclude deleterious effects on the retainer body and its associated components.
  • the whole invention retainer unit enables that it be keyed by a single conventional dowel pin which predetermines the precise punch or die position by a tight fit of the invention plug in the retainer and to the dowel pin.
  • the positioning of the dowel pin alone is predetermined by the positioning of the retainer body per se including the plug, and either the retainer unit including the plug may be removed and replaced or the retainer unit separated from the plug, which may serve to precision position a replacement retainer body.
  • the advantages of the invention become self-evident.
  • the fact that the locating dowel pin is on a common centerline with the punch or die button is very advantageous in the placement of several retainer bodies on a die shoe in versatile fashion as just mentioned.
  • the plurality of retainers may be commonly set and the holes thereof quickly transferred to a die shoe in the simple fashion described.
  • a further and inherent point of advantage in the use of the one dowel pin is that it avoids the potential problems of internal stress within a retainer body when a plurality of locating and orienting pins are used in parts which normally do not have a precision alignment.
  • tool element is used to describe a tool part or tool unit installed in or associated with a retainer body. This term is intended generically to define punch elements, die elements, drill bushings and like parts as disclosed herein.
