  • From the DE 10 2004 032 826 A1 is a method for producing stamped parts in a tool, in particular fine blanking tool, by means of at least one stamp, with which the stamped part is pushed out of a strip of material known.
  • the punched part is pushed from the material strip of this after being pressed out to a discharge.
  • the punch cooperates with a counter-holder in an insert when pressing out the stamped part, wherein the counter-holder the stamped part is lifted when opening the tool to the surface of the insert and the strip of material from the insert.
  • the strip of material is lifted by the cutting plate at a defined distance which corresponds at least to the thickness of the stamped parts.
  • the present invention seeks to improve a method and apparatus for producing fineblanked parts such that a vertical relative movement between strip of material and fineblanking part is completely avoided, reduces the necessary opening and closing path of the device and a simple structure the device is a use on high-speed presses possible, the fineblanking parts suffer no damage to the functional surfaces.
  • the solution according to the invention is characterized in that the cutting is carried out as an unfinished complete cut along the circumference of the fine blanking part with a special shaped cutting edge of cutting punch and / or insert such that the fine blanking part at partial connecting parts on the material strip at about its upper or lower level remains bonded cohesively in an altitude relative to the material strip and is moved together with the strip of material in the direction of the strip to a subsequent demolding, in which the partial connecting parts are separated from the strip of material shear forces without pushing back from each other.
  • the fine blanking part is cut to about 80 to 90% of its circumference completely from the strip of material.
  • the fineblanking part is held on the material strip by at least one, in particular two or more, connecting part (s). These connection parts are to be arranged so that they do not come to lie in the area of the important functional surfaces of the fineblanking part during later breaking.
  • connection points between the material strip and the fineblanking part are produced by the special shaping at the cutting edges of cutting punches and / or cutting plates in conjunction with the kinematics of the fineblanking press used, which are independent of the Thick variations of the material strip always moves in the same vertical position of the two decisive cutting edges.
  • At least one die insert is used interchangeable and associated with a die insert opposite cutting punch with partially shaped chamfers along their cutting edges.
  • the die insert is kept evenly biased along its circumference in the receptacle and projects beyond the base plate of the insert such that the die insert punctures the strip of material when closing the device on the punch, i. predetermined locations, can clamp without the base plate can engage.
  • the ready-held enemy cutting oil not only distributes the areal pressure unintentionally and then is no longer available to a sufficient extent when cutting.
  • the concentration of the fine cutting specific clamping forces on the die inserts continues to have the Advantage that the production of smooth cut surfaces on fineblanking part is supported.
  • the demoulding process by breaking the connecting parts between the fineblank part and the material strip in the demoulding stage must ensure that no vertical shear forces are transmitted to the narrow connecting parts.
  • the fine cutting part separated from the strip of material is removed vertically downwards to the running direction of the material strip by a drop stem in the cutting plate.
  • the device of the invention is simple and compact and has the great advantage that the required way to open and close the upper and lower part is significantly reduced. This is achieved in that in a receiving space of the cutting plate is arranged under uniform bias force-locking die insert is assigned, which is associated with the cutting punch, the cutting edges of Matrizentownes and / or the cutting punch provided with a special shape for incomplete cutting of Feinschneidteils from the strip of material are such that the fine cutting part and the material strip are materially interconnected by at least one partial connecting portion after cutting, and that in the cutting plate a chute for discharging the separated by a shear force removal from the strip of material fine cutting parts is provided vertically down to the direction of the strip of material ,
  • the special shaping of the cutting edges of die insert and / or punch consists of a partially shaped chamfer, which can vary in length and / width and / or inclination and interrupts the cutting edge of Matrizenmony and / or cutting punch accordingly, so that the fine cutting part of the strip of material not is completely cut and remains firmly bonded to partial connecting parts on the material strip approximately at its upper or lower level in an altitude relative to the material strip.
  • the space required for the transport of the composite of strips of material and fine blanking space within the interior of the device is achieved in that the die insert relative to the cutting plate has a height offset, which is dimensioned so that the required space for the material thickness downwardly protruding, however is still ensured on the strip of material fineblanking parts, so that the fineblanking parts can not be pushed back in the vertical direction or otherwise moved.
  • the opposite to the cutting plate protruding die inserts allow the clamping of the material strip and a concentration of fine cutting specific clamping forces around the cutting geometry around, which provides the advantage that the quality of the parting surfaces on fineblanking can be improved.
  • the die insert is interchangeable and can also be used several times after regrinding.
  • the one by the Regrind resulting height or material loss on Matrizenreheat can be compensated by placed in the receiving space under the die insert documents of different thickness very easily, allows flexible and cost-effective spare parts inventory with a high material utilization of Matrizenein algorithms.
  • Another advantage is that the lubricant stored on the inlet side in lubricant pockets remains in the pockets when the material strip is clamped because only a punctiform clamping of the material strip occurs around the cutting geometry and the previously common planar clamping of the material strip between upper and lower and lower part of the device is eliminated.
  • the inventive method and the device according to the invention are characterized by small opening and closing paths, so that high cycle rates and high output performance can be achieved, whereby the use of high-speed presses is made possible.
  • Fig. 1a to 1d a simplified schematic representation of the sequence of the method according to the invention.
  • Fig. 2 a sectional view of the design of the connecting portion between fine blank and material strips on the one hand and the design of die insert and cutting punch on the other hand and
  • fine blanking parts 1 are to be produced from a strip of material 2.
  • the Fig. 1a shows the device according to the invention with inserted strips of material 2 in the open state of the upper tool part 3 and lower tool part 4.
  • the lower tool part 4 includes a cutting plate 5, which has a receiving space 6 for receiving a die insert 7.
  • the Matrizenrus 7 is in the Fig. 1a shown as a simple tubular insert, but may also have other more complicated shapes. At its periphery of the die insert 7 is held for example by a screw, not shown in the cutting plate 5 under uniform bias, so that the forces occurring during cutting can be safely absorbed by die insert 7. The Matrizenrus 7 is thus removed from the receiving space 6 of the cutting plate 5 and can be reground accordingly if necessary.
  • the height loss of the die insert 7 compensated as a result of regrinding. It documents 8 are kept at different thicknesses, so that depending on the size of the regrinding different height losses can be compensated and the die insert 7 reaches the original height again.
  • the die insert 7 has a height offset H, so that the die insert 7 is significantly above the level of the cutting plate 5.
  • This height offset H is dimensioned such that it corresponds approximately to the material thickness of the material strip 2.
  • the upper tool part 3 and lower tool part 4 of the device according to the invention are opened so far that the imported material strip with the tailed fine cutting part 1 has sufficient space in the direction R of the material strip 2.
  • a chute 9 for discharging the fine cutting parts 1 is arranged approximately vertically downwards to the direction R of the material strip 2.
  • the die insert 7 is a punch 11 in the upper tool part 3 for cutting the fine blanking part 1 from the strip of material 2 and the chute 9 associated with an ejector 12.
  • the upper tool part 3 includes a press or guide plate 10 in which at least one cutting punch 11 and at least one ejector 12 are guided.
  • Fig. 1b shows the closed upper tool part 3 and lower tool part 4 with between die insert 7 and
  • the clamping plate is clamped around the cutting geometry, so that the fine cutting specific clamping forces are concentrated on a narrow range. This supports the production of smooth-cut separating surfaces on the fineblanking part 1.
  • lubrication pockets arranged in the cutting plate can be dispensed with and the lubricant supply on the material strip is available exclusively for the fineblanking process.
  • Fig. 1c shows the step of the method according to the invention, in which the cutting punch 5 has performed an incomplete complete cut in the strip of material 2 and the fine part cutting part 1 is cut to about 80 to 90% of its circumference.
  • Fig. 2 Reference is made, in which the fine blanking part 1 remains connected to, for example, a narrow connecting portion 14 with the material strip 2 cohesively after the cut.
  • the incomplete complete cut is achieved by a corresponding preparation of the cutting edges 15 of die insert 7 and / or cutting punch 11 in conjunction with the kinematics of the fine blanking press used, which always moves independently of the thickness variations of the strip of material in the same vertical position of the cutting edges of die insert 7 and cutting punch 11 , reached.
  • the cutting edge 15 of the die insert 7 can be broken, for example, along its edge profile by one or more chamfers 16.
  • the width and / or length and / or inclination of these bevels vary. This is aimed according to the size, geometry and after their distribution on the die insert 7 and / or cutting punch 11 as well as the thickness and quality of the material strip and the allowable shape tolerances radially and axially at the attachment points of the fine blanking part 1, which by the dimensions h and i on Matrizenerin 7 and the dimensions l and k is illustrated on the cutting punch.
