Definitions

  • the invention relates to a tool for punching complex die-cut images from a metal strip, in which the metal strip is shifted in a clock-wise manner in a slotted band guide elements arranged on both sides of this platen, along a single die plate, and in which the punch above the metal band is stamped by a column guided stamp receiving plate are displaceable in the direction of the surface of the metal strip, are arranged, the stamping stamps passing through a stripping plate above the metal strip and the stripping plate, the stamp receiving plate with the stamps and a pressure plate acting on the stamp receiving plate against the force of spring elements from an upper one Position are movable in the direction of the platen.
  • Such tools are generally known. They are used to punch die-cut images in contact plates above contact strips. Since the miniaturization of the electrical or electronic components also has to reduce the size of the connection contacts, complicated punching patterns result with very narrow contact paths remaining between the individual punchings. These complex die-cut images cannot be punched out in one punching process, but several punching steps are required.
  • the so-called follow-up composite tools required for this purpose have a die with recesses corresponding to the individual punching images which the contact strips or contact plates are guided along.
  • the stamps assigned to the individual stamping images are arranged above the contact strips and can be moved in the direction of the contact strip.
  • a stripping plate lies on the upper side of the contact strip during the stamping process, through which the stamps are also guided; she lies on the contact tape just before the stamps touch the tape surface. Only after the stamps have moved out of the punched portions of the contact strip does the stripper plate lift off the contact strip, so that the contact strip can be moved.
  • the scraper plate also serves to guide the sometimes very thin stamps.
  • the individual punching patterns required for the production of the contact part are carried out in known follow-on composite tools in a single die (cutting plate), which can reach lengths of up to 800 mm and more.
  • follow-on composite tools it is not possible to vary the punch pattern; for minor changes to the die cut, the entire die must be replaced with a correspondingly changed die, even if only a part of the die cut is affected.
  • this stripper plate In order to give the stripping plate, which is moved during the punching process, sufficient stability, this stripper plate must be dimensioned with increasing length in the case of complicated punched parts, whereby the mass to be moved is increased, which ultimately has an effect on a reduced achievable stroke speed. Another problem that arises with such stripper plates is that only one toolmaker can work on this stripper plate during their manufacture.
  • inserts are arranged in a base frame next to each other easily and quickly detachably. Since the subdivision of the work stations into functional groups as well as into individual follow-up composite tools requires a larger number of guide columns than a follow-up composite tool, and the connection of adjacent module plates requires additional overall length, the total length of such a tool in modular technology is compared to a follow-up tool.
  • Composite tool with a scraper plate significantly increased.
  • this modular design has the advantage that individual module plates can be quickly replaced when the punch pattern is changed, but also in the case of punch patterns prone to failure as part of maintenance work or malfunctions.
  • the individual slots with the individual modules are smaller and lighter at the same time. They can be manufactured, serviced and repaired independently of one another.
  • the individual scraper plates are much smaller and lighter; this has the consequence that the spring assemblies used can be dimensioned weaker. Due to the lower mass of the stripping plates to be moved per work station, an increased punching frequency with up to 2000 strokes per minute is possible.
  • the present invention has for its object to provide a follow composite tool in modular design, which allows standardization of different module parts, in which compared to the known module tools, the overall length is reduced and the belt vibrations as a result of that from the upper part , to which the stamps are attached, can be reduced or suppressed with the scraper plate raised.
  • the dynamic forces that are required for the movement of the wiper plate are to be reduced.
  • the support plate, the scraper plate and the stamp receiving plate are designed as a frame, into which several module plates with the individual punch patterns can be used one behind the other as seen in the tape feed direction, that the scraper plate is firmly connected to at least two columns, that these columns by means of a spring element in each case from a basic position in which the stripper plate is arranged slightly above the support plate, can be moved into a press-on position such that the band guide elements guided at least with one movement component in the direction of displacement of the stripper plate rest under spring pressure with their upper side against the underside of the stripper plates, whereby the sum of the Spring forces of the springs acting on the band guide elements correspond at least to the counterforce caused by the weight of the stripping plate and the spring travel corresponds to the distance between the support plate and stripping plate.
  • the design of the support plate, the scraper plate and the stamp receiving plate as a frame allows a simple variation of the tool when the stamping patterns are to be changed. Only the module plates are to be fastened in the frame, while the arrangement of the frames and their connection to the drive remains in the tool, so that an exchange can be carried out quickly.
  • a further advantage results from the fixed connection of the stripping plate to the columns, which together with the stripping plate form a kind of frame which shows increased stability compared to a stripping plate which is displaceably guided on the columns.
  • Each of these columns is acted upon by a spring element which acts in the area of the support plate into which the columns extend, the spring plate holding the stripping plate in a basic position by means of these spring elements, in which the stripping plate is lifted off the belt and thus releases the belt is.
  • the stripping plate is fastened by means of bolts engaging in grooves on the column.
  • the columns in the support plate are preferably displaceably guided in guide bores and the spring elements assigned to the columns in recesses in the guide bores inserted and in such a way that they engage in a groove in the groove on the respective column.
  • the stripping plate should be lifted off the top of the contact strip.
  • the groove is a radial annular groove with a wedge-shaped cross section, as seen in the axial direction of the columns, so that the basic position is determined by the spring element engaging in the groove.
  • the angle enclosed by the surfaces of the wedge-shaped groove in cross section should be between 90 ° C and 120 °, so that on the one hand a sufficiently stable position is achieved and on the other hand the columns can still be moved against this spring position against the spring force.
  • Spring rings are preferably used as spring elements, which lie in the annular groove, or spiral springs, which are inserted in bores running radially to the column and bear against a ball which engages in the groove of the column.
  • the columns are aligned in at least one row and a continuous bar is placed on the front ends of the columns which act on several spring elements.
  • These springs which are not assigned to a specific column, can be replaced without special measures, ie in particular regardless of the number of columns.
  • the strips preferably form parts of an upper frame in which they are held in a stop position by the springs.
  • the top frame forms an interchangeable unit with the cross bar and the spring elements.
  • Such a configuration is particularly advantageous in connection with the stripping plate designed according to the invention, since it makes both the lower region and the upper region of the punching tool extremely variable.
  • the specified top frame can, however, also be used in punching tools in which stripper plates and belt guide elements of a different type are used.
  • the tool has a support plate 1, a scraper plate 2, a stamp receiving plate 3 and a pressure plate 4 one above the other.
  • Support plate 1, stripping plate 2 and stamping plate 3 each have a chamber 5 into which module plates (not shown in more detail) can be inserted.
  • a module plate with the stamps corresponding to the stamping pattern is screwed into the stamp receiving plate 3, a module plate 5 with guide openings through which the stamping stamps pass and the support plate 1 module plates, which likewise have openings corresponding to the stamping pattern, into the stripping plate 2.
  • the scraper plate 2 is immovably arranged on columns 6 on both sides.
  • the stripping plate 2 In order to be able to release the stripping plate 2, it is fastened to the columns 6 by means of a bolt 7, which engages in a corresponding groove 8 on the columns 6.
  • the column or the corresponding plate is guided displaceably in the support plate 1, the stamp receiving plate 3 and the pressure plate 4.
  • FIGS. 2 to 4 show band guide elements 9 which are inserted into the support plate 1 in blind bores, where they each abut against a spring 10.
  • a slot l2 is present in which the metal strip l3 guided over the support surface ll lies with its edge.
  • ring grooves l5 are formed, in each of which a spring ring l6 is seated with a round cross section, which in turn engages in a radial groove l7 of the columns 6.
  • This radial groove 17 has a wedge-shaped cross section, the surfaces of the groove preferably enclosing an angle of 110 ° to 120 °.
  • Figure 2 shows the arrangement in an upper dead center position.
  • the scraper plate 2 is lifted off the metal strip l3, so that the metal strip l3 can be moved in the slots l2 of the strip guide elements 9 along the contact surface 11 of the contact plate l.
  • the spring ring l6 lies in the bottom region of the radial groove 17 of the columns 6; the band guide elements 9, which are bolts which are round in cross section, rest with their upper end face on the underside of the stripping plate 2.
  • the stamp receiving plate 3, against which the pressure plate 4 rests is moved into an upper end position in which the stamping stamps, not shown, are pulled out of the support plate 1 and the metal strip l3, but guided in the stripping plate 2.
  • spring elements 18 arranged in the pressure plate 4, which press against an insert 19, are first moved downwards in the direction of the support plate 1.
  • the insert l9 comes to rest on the upper side of the column 6 and moves it downward and thus the stripper plate 2 which is firmly arranged thereon and which firmly presses the metal strip l3 against the support plate l.
  • the actual stamping process takes place, in which the stamping stamps attached to the stamp receiving plate 3 penetrate through the metal strip l3.
  • the direction of movement of the pressure plate 4 is reversed and thus the stamp receiving plate 3 is moved upward with the stamping stamps.
  • the scraper plate 2 initially remains in its pressing position until the punches are completely pulled out of the metal strip l3.
  • the columns 6 are released via the projections 20 on the inserts 19, so that the columns 6 are shifted into the stable position according to FIG.
  • the stripping plate 2 is lifted upwards.
  • This type of belt guide suppresses belt vibrations at high stroke or punch frequencies.
  • the columns 6 can be released from engagement with the spring elements l8, for which the ring grooves l5, in which these spring rings l6 are seated, are designed to a depth such that they can completely accommodate the spring rings l6.
  • Figure 8 shows the structure of the modular tool. It has a lower plate 2l on which individual inserts 22 of standardized length are positioned one behind the other in the central region via guide openings 23. The individual module plates with the respective punching pattern are inserted into the chambers 5 of the individual inserts 22. The inserts 22 are clamped at their lateral edges by fastening elements 24. These fastening elements 24 are spaced apart from one another by means of spacer blocks 25 and engage in undercuts (not shown) in the form of webs and ribs on the lower plate 2l. This type of attachment of the inserts 22 permits a slight variation in the sequence of the inserts, which can be exchanged quickly and easily. At the end of the lower plate 2l, two pillars of the base frame are visible on one long side.
  • An individual spring element 18, which acts directly on the end of the respective column, is usually assigned to each column 6.
  • the entire upper part must be used when increasing the number of columns 6 be replaced.
  • an upper part 26 is used, as is shown schematically in FIGS Figures 5 to 7 is shown and that in its function the pressure plate 4 with the spring elements l8 and the inserts l9.
  • the upper part 26 has a frame 27 with through bores 28 into which individual springs 18 ′, which correspond to the spring elements 18 of the embodiment according to FIGS. 2 to 4, are inserted.
  • the upper part 26 is closed by a cover plate 29 on its upper side.
  • a bar 3l is inserted into a longitudinal groove 30, which can move in the region of a guide groove 32, as can be seen from the different positions in FIGS. 6 and 7.
  • the bar 3l is pulled out.
  • the columns 6 are to be exchanged independently of the position of the springs l8 ⁇ and their spatial arrangement can be changed. When increasing the number of columns, only stronger springs l8 ⁇ are used in the upper part 26 in a simple manner.
  • the upper part 26 shown in FIGS. 5 to 7 is not only suitable for a base frame, as can be seen in FIGS. 1 to 4, but it can also be used in tools in which the stripping plate and belt guide elements are guided differently.
