  • 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 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, for cutting, a die insert which can be inserted in a receptacle of the insert and a punch used with partially formed bevels along its cutting edges are used, and in the demolding step the partial bond parts are separated from the strip of material without pushing back
  • the fine blanking part and the material strip are demolded downwards by a shear force-free breaking perpendicular to the running direction of the material strip, wherein the demoulded fine blanking part is removed through a chute in the cutting plate.
  • the fine blanking part is cut to about 80 to 90% of its circumference completely from the strip of material.

  • 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 inventive device 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 a uniform bias force-locking die insert is associated with the cutting punch, wherein the cutting edges of the die insert and / or the cutting punch by a partially shaped barrel for incomplete cutting of Feinschneidteils from the strip of material are interrupted, such that the fine blanking part and the strip of material by partial connecting parts are materially interconnected after cutting, and that the die insert relative to the cutting plate has a vertical offset for partial clamping of the strip of material on a press or guide plate, and that in the cutting plate Downshaft for discharging the separated by a shear-free breaking off the strip of material fine cutting parts is provided vertically downwards to the direction of the strip of material.
