Make order necessary. In the case of the earlier Use of separable elements in a common mold unit are also known constructions Very costly to manufacture, complex to design and essentially require complete disassembly the unit to remove and replace elements. In addition, they have known constructions little flexibility in the definition and change of work patterns and offer problems in the upright position maintaining the alignment accuracy between the held elements and the underlying molds.

The special, but not exclusive, field of application of the invention are cutting or punching dies or shapes, which are used to produce slot-like Multiple perforations can be used in closely spaced relationship and in any desired pattern. In the illustrated embodiment, a cutting tool or punch holder is shown, v / elcher has a continuous frame which defines a passage opening with its edges. A number of complementary ones Insert parts of variable size and shape can occupy the passage opening and interact with one another, by making spaced openings for the shafts of the necessary work tools determine. Due to complementary, intermediate fitting and centering formations on the insert parts and on opposite edges of the passage opening in the In the frame, the insert parts have a precise sliding fit in the frame. Each insert part is through its use positively held in the frame against lateral physical movement, while having a relatively independent longitudinal movement is possible and is therefore for an independent insertion into the frame and a corresponding removal

Fig. 9 is a view similar to Figs. 7 and 8 showing a Application of the double-purpose hatchet, and

Fig. 10 is a partially schematic plan view of a retaining plate arrangement according to a further embodiment the invention.

As shown in FIG. 1, an E'orman arrangement comprises in accordance with an illustrated embodiment of the invention an upper mold unit 10, a lower mold unit 11 and a stripping plate 12 arranged therebetween Parts occupy an overlying, aligned relationship with device 10 and device 11 are fastened in a suitable manner to respective overlying and underlying shoe carriers, which are above the carrier 13 lie, which is partially shown in FIGS is.

The molding unit 10 comprises a rigid continuous frame 15ϊ which within its edges a generally rectangular through opening 16 forms. End walls 17 of the Apertures 16 are flat in this form of the invention. Side walls are in a continuous series of consecutive, adjacent arc-shaped recesses 18 formed, as by drilling along successive Centers, with the adjacent arcuate recesses between the same intermediate, short, sharp-edged partition walls 19 determine. The series of arcuate recesses 18 is continuous along each side wall of the opening 16, and the Recesses in the respective opposing walls are arranged in directly aligned pairs. Any pair of Recesses 18 are set up precisely for a sliding fit within the frame 15 of an insert part 21.

1 0 9 8 1 R / 1 R? 1

Each insert 21 has a generally elongated rectangular configuration. Its stretched lengthways Side walls 22 and 23 represent flat, parallel, flat bearing surfaces. However, its respective ends are rounded in an arc shape, with their curved contours conforming with and complementary to the shape of the arcuate recesses 18, in polygamy they sit in sliding through one face of the frame 15 can fit into it. The depth of the inserts generally corresponds to the depth of the receptacle ahm ens.

As can be easily seen, the frame 15 can be independent and selectively receiving therein a plurality of side-by-side inserts 21, their contiguous flat sides lie against one another in the same extent and in a bearing-like manner between the oppositely curved !? frame segments 19 extend from one end to the other.

In the embodiment shown in FIG. 1, the opposite side surfaces 22 and 25 of each insert each provided with a cutout, for example is milled out to form an identical channel-like recess 24 therein, the base of which is flat and the ends of which are essentially ζμ shaped in a 90 ° bend. If the Frame 15 is filled with the inserts 21 in order to form a mold bed, the recesses 24 stand in adjoining one another Surfaces in complementary engagement with one another to in each case a through opening 34 in the mold bed form whose opposite wall surfaces are flat and parallel and whose ends are each in the form of a 180 ° arc are trained.

In the vicinity of each of its ends, each insert 21 has a centered through opening which defines a bore 25, which is reduced in diameter towards one end and provided with a thread which extends from its surface

10981R / 1fi? 1

opens, which is oriented so that it is on the support shoe is present. In one or both ends of the insert 21 is at the apex of its curve and between its vertical ones Boundaries arranged a pear-shaped arched recess, which a cam surface 28 forms.

Centered within the frame 15 and in the wall which defines each of the arcuate recesses 18 and within its vertical boundaries from one end of an inclined bore 31 ₅ which is formed in the frame 15, a (part of a ball 29 in front. The ball is supported by a compression spring 32, which has an expansion fit in the bore at the end which is remote from the ball 29, whereby this end opens on the surface of the frame;. which is designed to rest on the ßtützformschuh When each insert for sliding in is brought into the frame, their end faces push the associated ball or balls 29 back into the bores 31 until the balls align with the recessed cam surfaces 28. When this occurs, the balls snap into the recesses 28, whereupon the insert is locked in a precisely positioned position with respect to the frame 15. By inserting a pin into a bore 33, the ball 29 can be shifted slightly to the end of an insert to facilitate the sliding removal of the insert, as and when there is a need for it.

As already noted above, the arrangement of the various insert parts 21, according to which they are laterally are arranged next to each other and in contact with each other, the complementary recesses 24 of adjacent ones Divide into an opposing arrangement in such a way that they interact between such Define part openings 34. The openings 34 provide one

1 0 9 Π 1 R / 1

_9-2047379

remote installation in the mold bed, which is achieved by the inserts of the shafts 35 of the blade-like cutting tools 30 is formed. A shaft end 35 of each blade element is shaped and designed so that it is exactly in an opening 34 with a complementary seat in the united Recesses 24 of adjacent inserts is arranged. As is easy to see, the shafts have 35 in cross-section each flattened and rounded sides Ends, and the fit is such that their projecting projections 37 are stably located and precisely aligned as they protrude from the mold bed and extend against the lower mold plate 11. According to the in Fig.2 illustrated embodiment of the invention are corresponding openings are provided in each shaft 35 and in the recessed surface of an adjacent insert part. These corresponding openings enable according to the illustration an arrangement of one side of a tool shank in a recess 24 of an insert 21, wherein align the openings, whereupon a dowel pin can be used with an interference fit therein. The fit is chosen so dalö the tool easily removed from the insert and can be easily replaced. With this unitary relationship between a tool and an insert, since the inserts are loaded into the frame 15 in such a way that they are arranged side by side the tools 30 arranged and locked simultaneously therewith in an obvious manner.

With reference to the upper mold unit 10 it can accordingly be seen that after the assembly and attachment of the upper support plate or upper shoe 13, the shoe while the adjacent ends of the bores 31 and 35 are closed will serve as a means to provide a reaction surface against and through which to act on the tools when Stresses acting on the cutting process uniformly un <"

common can be derived in a highly effective manner.

ItLe lower mold unit 11 comprises a frame 38, inserts 42 and a locking device for the inserts, which in all respects with the frame 15, the inserts 21 and the locking device of the upper mold plate are identical. Form according to the arrangement in the frame 38 the inserts 42 in a corresponding manner between the adjacent ones Sides of the same through-openings 4-3, which in vertical alignment with the through-openings 34-in of the upper mold unit and thus arranged in an identical configuration to the working ends 37 of the cutting tools 30 to let through in the shape cutting operation. It is to be noted that, at the instant illustrated, the ends of the tools 30 have a configuration which is generally corresponds to the configuration of the openings 43, however with a little smaller size. Obviously, if necessary, the openings 43 can be made with any desired Cross-sectional configuration can be provided by a simple modification of milling the sides of the inserts 42.

In any event, it is readily apparent that the molding unit under consideration is an essentially universal tool and that in the great majority of cases, apart from the absence of the cutting tools, the lower die unit is one May have stack shape which is identical to that of the upper mold unit.

In Fig. 1 an intermediate wiper device 12 is shown, which can take any conventional form. It is shown here as a plate 44 which is arranged between the mold units 10 and 11. The stripper plate is held in place in a suitable manner and in a conventional manner so that the through-holes formed therein

109HIRMR ¹ M.

openings with the openings 34 and 43 in the upper and the align the lower standard unit. In accordance with the usual mode of operation of the lOrinaiiordnuiigen of this species if a workpiece W is moved over the lower mold plate 11 and reaches the working position, the upper mold device lowered through the middle of the attached shoe, with the ends 37 cLer tools JO, which with engage the workpiece, pass through the wiper openings 45, penetrate the workpiece W, and enter the openings 43 provided for this purpose in the lower plate 11 with the entrainment of workpiece particles. As is evident, as the upper mold unit is raised, the work tools are withdrawn with it, the stripping plate 44 having a subsequent lifting movement of the workpiece W excludes.

The construction and arrangement of the leile is unique and provides door parts significant in the art, particularly with regard to the replacement of a spent or broken one Tool. Since every insert unit and every tool 30 individually and precisely thanks to a sliding fit in the frame 15 is arranged, you only need one of course To apply the pin in the passage or passages 33 to the respective ends of the insert concerned, to remove the ball locking element 29 from the insert, whereupon by grasping the tool 30 the Ein ™ Set and the tool at the same time and easily out of the] mold bed can be pushed out. It does this without interfering with any of the other inserts or tools and ensures that after the insert t has been replaced with a new tool, if necessary and in is carried out in the manner described above, the new tool is precisely and firmly in the required orientation is arranged. It should be emphasized that the other insert parts are unaffected at all times, as they are

1 0 9 R 1 R / 1 R

acting engagement of their arcuately curved ends with the "arcuately stepped sections 18 of the frame 15 be held.

It should be noted that the maintenance work is not special Require skill, no disassembly of the formulas, 'direction become necessary and can be carried out within an extremely short time. Of course, they will be worn out or damaged inserts 42 of the mold unit 11 are replaced and removed in a similar manner.

The same facility available when removing and replacing worn parts is also available when one wishes to change the character of the tools or the pattern of the tools within the frame of reference of the mold bed wishes to change which is provided by the mold unit assembled according to the invention. It should It should be obvious that an interrupted pattern of tools is possible if this is done according to the requirements of the Workpiece is required to which the arrangement is applied.

According to the inventive concept, insert parts can be provided legs whose sides are shaped differently than in the examples shown in FIGS. 1 to 3. According to the illustration in FIG. 8, for example, a multiplicity of channels can be formed in an etched part 46. In addition, the channels shown there can be either similar or different in size. The only requirement is that the insert parts must be designed to be complementary to the channels. Thus, when the insert parts 46 are used in the frame 15 according to FIG their neighboring bait in order to form passageways lu in the diet-formed forabett.

109816/1521

20A7378

Again, special attention is to be paid to the fact that it is to be provided that the inserts must be complementary to the cutouts located therein, that the cutouts however, they do not have to be uniform. This enables a wide variety of tools to be used in Connection with the molding unit can be applied and used. In addition, the possibility is created that the molding unit is applicable to a wide variety of applications in which the openings, the to be formed in a workpiece in a single cutting operation are numerous and closely spaced. Accordingly If the inserts are designed in accordance with the elements 46 of Figure 8, one can be selective Achieve a remote tool pattern, which has the ability to use different tools at different points in the Form to apply.

As an alternative, the inserts can be optionally shaped as at 21 as shown in Figure 7 of the drawings is. Here the inserts are indicated by the reference numeral 48 and have one side which is not interrupted and is flat, while a channel is milled out in its other side, which represents a recess 49. The base of the recess 49 is flat, while the respective ends are curved so that arcs of substantially 180 ° can be formed. Thus, when inserting a series of inserts 48 into frame 15, such inserts can be used so that the channel or recess 49 on one side of an insert 48 through the flat and uninterrupted Side of the next adjacent insert 48 is covered, which is next to the previous one. Through openings 51 are thereby defined to the shafts of the work tools in the type of openings 34 described above. It should be noted that these openings the openings 34 are similar in cross-section, since di *

10981R / 1R

Sides are flat and the ends are essentially in the Form of 180 ° bend are formed. When assembling the insert parts 4-8, which have the same peripheral size as the inserts 21 may have, in this modification of the invention all insert parts are arranged so that they face in the same direction, creating a recess or channel 4-9 a flat planar side part of an adjacent EiiH & tzes faces. The advantages of this application variation consist in that the channels or recesses only need to be formed on one side of the insert. As is of course, can of course in this case, as in the formation of any insert part according to the In accordance with the invention, more than one channel or recess can be defined along the side of an insert.

According to the illustration in Figure 4 of the drawing, a unitary structure of an insert and a tool can be formed without the need for dowel pins or to use other fasteners. The one shown there Insert 52 is constructed like insert 21 except that it has a top surface thereof is cut away to form a recessed shoulder 53. In a cooperative relationship there is a Blade element 54, which at the upper end of its shaft is equipped with a folded flange 55 which forms a head on the tool. According to the way they work together blade member 54 and insert 52 becomes the body of the shaft of the element 54 · in the channel or in the cut-out recess 56 of the insert part 52 added to hold its base while the flange 55 is held in an adjoining relationship with paragraph 53 will. The outermost surface of the flange 55 ', which forms the head of the tool, is arranged to be with the adjacent one Surface of the insert 52 is aligned. When inserting

1 0981R / 1K? 1

a series of inserts and tool units in the manner indicated above, the inserts in a side by side maintained relationship to enclose the shanks of the tool parts 54 · therebetween. In the application of the frame 15 to rest on the upper mold shoe or the support plate are also the heads of the respective Tools in a fastened relationship to the shoe and Paragraph 53 in brackets. This means that when inserting the parts thus assembled into a plate 15 and in their alignment the work tools are in a fixed and positively positioned relationship with their protruding ones Ends are arranged, and the tools are equipped with a wide support head, which against a significant surface area of the support part presses. It is of course obvious that missions other than im In the context of this modification, they have a configuration and function similar to that of insert 21 the case is. As in all other cases, a single blade element and its insert can be individually made from the Assembly can be removed without disturbing other parts. The individual and precise positioning of the respective operations and the work tools are used to ensure that when removing an insert and a tool these are again in their desired relationship to the other components of the mold assembly after replacement.

The inserts of the various modifications described above have a relatively narrow fitting and bearing relationship, and a eolohe to a narrow Singriff and a long Lagarkontakt with the shanks of the working tools to ensure, regardless of whether it is tools or other to the blade members, punching Tools are what penetrate workpieces.

If a particular application requires a facility to be required to accommodate changes in the To compensate for dimensioning from end to end of the frame for the inserts, the invention provides one for this Solution as in the Pig. 5 is illustrated. In this embodiment of the invention the frame is at 57 and corresponds to the frame 15 in configuration. The frame 57 defines a similar through opening and receives inserts 59, which the inserts 21 in are similar to the embodiment described first. The inserts have a sliding fit and are in the same Kind of kept as described above. "In this case, however, there is at least one flat end face the opening 58 with one or more arcuate recesses 61 formed, which have a conical tapered configuration, the longitudinal axis of which in the plane of the Flat end of the opening 58 is. Each recess 61 is filled by a socket 62 with a corresponding complementary configuration. The outer surface of each socket 62 is defined by a flat even surface, which is in a Plane runs which is common to the flat end face of the opening 58. As can be seen from FIGS. 5 and 6 of the drawing , the insert 62 is suitably drilled lengthways to thereby extend the screw receive, which is designed so that it is in threaded engagement with the covered recess, which in the Support shoe 13 is set. It should be noted that the The length of the socket 62 is slightly less than the depth of the frame 57. Accordingly, it is possible that when rotating the Screw 63 the socket 62 can be raised or lowered in its recess. By setting the bearings appropriately or the socket 62 can set any end game in the frame 57 and ensure that the on the inserts related holding surfaces, which form the mold bed, are not adversely affected, where for some reason the

10981R / 1

Dimension from end to end of the through opening of the frame is influenced by external factors. It should be the fact Attention should be paid that it is not just the displacement of the end faces that is at stake here. The contemplation rather, it is aimed at any undesirable effect, which deviations in the required positioning of the ends of the frame with respect to the sides.

In the pig. Another embodiment is shown in Figure 9 of the drawings to provide control of the breathing of a frame as in Figure 15 where the die cutting environment may tend to create problems in that direction. As shown in the Pig. 9 , certain inserts 21a of the insert part 21, which form a mold bed as in FIG. These extensions 64 are provided with openings to thereby receive the extension of diamond-shaped locking pins which are suitably attached to protrude from the surface of the frame 15. This ensures that the side-to-side dimension of the continuous frame is controlled by means of the releasable connection of the spaced-apart inserts to the frame. The members 21a accordingly serve as fastening pieces which prevent the expansion of the opening 16 in the course of a "breathing" phenomenon, which can accompany the application of the format arrangement under certain conditions. Diamond-shaped pins are preferably used; / iu eij is shown. However, these can be replaced by registration pins. In any case, the insert parts 21a can easily be taken out of the arrangement Lcra, without previously complex and difficult to handle loading

As working tools, for example, those have been described which have no heads, whereby they are by dowel pins or in some other way with a neighboring insert are positively connected or those which have heads with a bent flange forming a head between a portion of an insert fits into it. However, this is not to be taken as a limitation. There are others Concepts possible, which also include the possibility of using the blade elements or knife elements simply an interference fit in the openings 34 or a sliding fit with suitable releasable locking devices.

It is obvious that the conception of a continuous or continuous frame with insert parts, which have therein a sliding fit and with changeably mountable, easily removable cutting tools in one considerable possibility of variation as well as considerable flexibility is accessible, some aspects of which have already been mentioned. It is quite obvious to the person skilled in the art that there are many possible variations and modifications exist, which can be derived from the basic concept outlined here. For example, in manufacturing of the frame, the recesses 18 can be formed in various ways, as long as their configuration is accurate Centering an insert used prescribes which has complementary end correspondence. Furthermore it should be noted that the distance between aligned recesses can also be varied to be longer and longer to accommodate shorter utility toilets, v / elche in turn for fastening of differently shaped tools can be milled or formed in a suitable manner.

It is further evident that the "use of individual inserts and tools according to the invention gives rise to essentially infinite variation in the pattern and spacing of the cutting tools used". It is in any lalle a feature of the invention that the use of parts is inherent in its predetermined frame proper alignment and positioning of an individual, thereby to request the ^exchange; Replacing and ivy setting the tool is possible. i

It continues the concept of an identically trained Formbed own, as it is turned off by the units 10 and 11 ( is that a sentence which forms an I-shape arrangement, can be achieved at the same time, so that their exact identity is guaranteed. For example, those affected can Elements that are to be arranged one above the other are arranged directly one above the other for production, which are first distinguished by the spaced apart openings 66 and 67, which are shown in the drawing in FIG the respective upper corners are recognizable. The opening 66 can then provide a reference point for establishing X and X coordinates deliver, whereby the position of the passage opening, like the through hole 16 and the centers of the arcuate - Recesses 18 can be designed in accordance with the preliminary requirements. Furthermore, the | Openings 66 the insertion of a dowel pin so that the stacked plates are aligned so that that they are secured against any other relative movement than an arcuate oscillating movement. A diamond-shaped one Pin, which is in the other opening 67 of the respective. Plates arranged can thereby be used to limit the relative arcuate movement and around the Allow plates to move- slightly to not entirely exact Set tolerances. When the stacked

1 Π 9 R 1 R / 1 F? 1

Parts are held in this way, a series of holes or other machining of the plates can be carried out at the same time, so that openings such as openings 16 as Result will be formed. Accordingly, an upper and a lower mold plate produced according to this method can be a have an identical structural configuration, which leads to a high degree of alignment accuracy of the subsequently used inserts and the openings which are intended for the tool holder and which they define.

As described, the inserts are through a ball lock connection kept within their respective panels. Other holding methods - are possible, for example they can be held in place by using adjustment screws or by an interference fit.

According to the illustration in FIG. 1, the rectangular opening 16 in the upper frame and the corresponding opening in the lower frame offer the possibility of receiving rows of insert parts arranged side by side and for an arrangement of tool or blade elements, which are either aligned in a line or in one separated pattern can be arranged. If desired, other formations are possible, for example a circular pattern as shown in FIG. Here, an open plate 68 forms a frame which comprises one or more arcuate openings 69, the inner and outer radially spaced peripheries of which are notched at the edge so that arcuate recesses 71 and 72 are formed. Of course, there are the outer recesses 71 on a larger radius than the aligned inner recesses 72. inserts 73 according to the configuration are provided, which have a slip fit at their ends opposite the aligned recesses 71 and 72, wherein the insert parts in this case on their sides one himself

109fc 1 R / 1 K

have tapered configuration which takes into account the radial aspect of the frame opening. On the other hand, due to their sliding fit in the frame, the inserts are arranged with their side surfaces in bearing contact with one another, as is the case with the other embodiments, and the sides are shaped so that through-openings 74- are defined by the engagement s-channel configuration. According to any of the above alternatives, shafts of blade-like or knife-like tool elements 75 are arranged in the openings 74. Again, the inserts 73 are held or secured within the frame defining plate 68 by the cooperation of suitable retaining means such as the ball locking means and related structure referred to above. To illustrate the versatility of the inventive concept, it should be noted that in the I ¹ Ig. 10, due to the circular spaced-apart rows of openings 69, a unique cutting pattern can be achieved in that each opening receives a conforming arcuate row of inserts 73 and corresponding tool elements.
