Definitions
- the invention relates to a method for producing stamped parts with largely smooth cutting and enlarged functional surface, in particular a workpiece by fine blanking and / or forming from a strip of tape, wherein the tape strip between one of a cutting punch, a guide plate for the cutting punch, one on the Guiding plate arranged ring teeth and an ejector composite upper part and a cutting insert, ejector and an inner mold existing lower part clamped when closing and forced separation in the cutting zone by shearing at high compressive stress, previously pressed the ring prongs in the tape strip and a compressive stress on the cutting tape strip is exercised.
- the invention further relates to an apparatus for producing stamped parts with a substantially smooth and enlarged functional surface, in particular a workpiece by fine blanking and / or forming a strip of tape, with a two-part tool, the at least one of a main cutting punch, a guide plate for the cutting punch, an the guide plate arranged ring spike and an ejector together upper part and a composite of a cutting plate, an ejector and an inner mold punch base comprises, wherein the tape strip is clamped in use between the guide plate and cutting plate and the ring prong is pressed into the tape strip.
- a generic method and a generic device are known from the article "fine blanking, a rational manufacturing process", special edition "sheet metal", September 1959, No. 9.
- Typical features of fine-cut parts are also the edge indent and the cutting edge.
- the feeder which increases with decreasing the corner radius and increasing sheet thickness.
- the insertion depth can be approx. 30% and the feed width is about 40% of the sheet thickness or more (see DIN 3345, fineblanking, Aug. 1980).
- the feeder is thus dependent on the material thickness and quality, so that its control is limited and often brings a limitation of the parts function, for example, by a lack of sharp edges of the corners of teeth or by the induced change in the functional length of the parts, with it.
- the punch pull therefore reduces the parting function and forces the manufacturer to use a thicker stock.
- the well-known shear press after DE 2 127 495 A1 is operated at a higher hydrostatic pressure exerted in the whole area of the workpiece subjected to plastic deformation.
- This high pressure is generated in particular in the vicinity of the tool edges by an upper jaw provided with a projection.
- This projection effectively takes on the function of the ring point, which after the DE 2 127 495 A1 not available.
- the feeder is ultimately not eliminated and material volume is displaced along the cutting line, which is accompanied by an increased risk of cracking.
- the workpiece is machined in a single-stage arrangement in at least two successive successive successive step sequences in different cutting directions, in a first cutting operation in the vertical direction cut a tailored to the workpiece geometry semi-finished product with a small indentation and cut in at least one other cutting operation in the opposite direction the part becomes.
- the collection of the first part of the step is to be replenished at least in the corner.
- predominantly the projecting punching burr is avoided.
- the feeder is ultimately not eliminated and material volume is displaced along the cutting line, which is accompanied by an increased risk of cracking.
- the present invention seeks to avoid the tendency to crack cut surfaces and the edge feed of fineblanking parts by targeted control of the stress state in the cutting zone and at the same time perform the fineblanking of thicker parts with higher process reliability economically and effectively.
- the solution according to the invention is characterized in that it is possible for the first time to economically apply the fine blanking process to parts, for example toothed parts of greater thickness without tears and sharp edges without post-processing and material displacement along the cutting line.
- the parameters for controlling the state of stress in the cutting zone for example the volume of material to be postponed depending on the type of material, shape and geometry of the workpiece can be determined by a virtual forming simulation, after which then the tool elements for the Nachschieben the material in the direction Cutting zone are designed.
- the inventive method thus covers the fine blanking of parts in a wide dimensional range, for example, parts up to large thicknesses and complicated part geometries, such as gears on gear parts, in high quality.
- even inferior steel grades can be finely cut without running the risk of tears on the cut surfaces.
- the device according to the invention has a simple and robust construction.

- Fig. 6 a section through the device according to the invention with free cut in the tape strip in the half-cut state.
- the Fig. 1 shows the basic structure of a fine cutting tool according to the prior art in the closed state.
- the fineblanking tool has an upper part 1 and a lower part 2.
- the upper part 1 of the fineblanking tool includes a guide plate 4 having a serrated edge 3, a cutting punch 5 guided in the guide plate 4 and an ejector 6.
- the lower part 3 is formed by an insert 7, an inner mold or punch 8 and an ejector 9.
- the cutting plate 7 and the inner mold waste have cut the fine cut part 11 at about half the workpiece thickness.
- Fig. 2 is in detail the cutting zone according to the prior art according to Fig. 1 shown.
- the tape strip 10 is located between the cutting plate 7 and guide plate 4.
- the ring spike 3 presses the tape strip 10 with the ring-tooth force FR on the cutting plate 7.
- the cutting punch 5 works with the cutting force FS against the counter-holder, here the Ejector 9, applied counterforce FG.
- the cutting force FS is dependent on the outer and inner cut line length of the part, the thickness, the tensile strength of the material to be cut and an influencing factor, the yield strength to tensile strength ratio of the workpiece material, the geometric shape of the cutting part, the tool lubrication and the Dulling of the cutting punch 5 and the cutting plate 7 taken into account.
- the inventive device of Example 1 substantially corresponds to the structure of the device, according to Fig. 1 has been described, but with the difference that a ring tooth 3 is arranged on the cutting plate 7.
- active tool element 13 is provided in the cutting line direction SL with the corresponding force FW the strip of tape 10 acts.
- the tool element 13 is supported on the one hand on the cutting punch 5 and on the other hand in a recess 4 introduced in the guide plate 4 vertically displaceable from the tape strip.
- the tape strip 10 has no cutout and the active tool element 13 is not yet engaged.
- the tape strip 10 is in the clamped state between the upper and lower part of the device according to the invention.
- the lower ring spike 3 has penetrated into the tape strip 10 and the guide plate 4 presses with the corresponding, generated by the pressure pin 15 force FF on the tape strip 10th
- Fig. 4 has the cutting punch 5, the tape strip 10 cut approximately halfway.
- the active tool element 13 has also moved into the material of the clamped tape strip 10, wherein the tool element 13, the cutting punch 5 lags slightly.
- Fig. 5 is illustrated how the active tool element 13 during its penetration into the tape strip 10 in cooperation with the lower ring point 3, the material moves almost transversely into the cutting zone.
- the state of stress in the cutting zone constantly corresponds to a compressive stress which can be adjusted accordingly by the control of the tool element 13 as a function of the material type, shape and geometry of the workpiece.
- the process parameters for the tool element 13, for example the force FW to be exerted, the hydraulic pressure for generating the force FW or the amount of the lag NE relative to the cutting punch 5, are determined as a function of
- the material type, shape and geometry of the workpiece are determined by a virtual forming simulation, in which the material flow in the forming process is shown, strains and reference stresses are analyzed to determine whether the deformation can be made and the loads can be borne by the tool elements.
- the parameters for determining the force FW of the active tool element 13 can also be determined on the real fineblank part by individual measurement. This requires a series of experiments and their evaluation in order to be able to interpret the active tool element 13 accordingly on this basis.
- a differential stamping die penetrating into the workpiece from the stamp side can be used, which is in operative connection with a controllable hydraulic system.
- the process according to the invention proceeds in such a way that first the strip of strip 10 is clamped between upper and lower part 1 or 2. From the beginning to the end of the cutting process, pressure is selectively exerted by the controlled hydraulic system in the region of the cutting zone with the pressure pin 12 and the active tool element 13. As a result, a corresponding state of stress is achieved in the cutting zone, which acts as a compressive stress during the entire cutting process. This leads to an improved surface quality, especially with poor material quality. With the targeted embossing by the active tool element 13 is a superposition of the cutting process with a transverse flow QF of part material in the cutting zone reached, whereby at the same time the punching in this area noticeably reduced. The lower serration 3 assists the transverse flow QF of the material into the cutting zone.
- the Fig. 6 shows a further variant of the device according to the invention, which in its basic structure, the structure of in Fig. 3 corresponds described device.
- a support ramp 16 is provided on the cutting plate 7, which comes to rest in the free cut 17. The support ramp 16 prevents the material from flowing in the width. All other operations are the same as in Example 1.
