Definitions

  • the invention relates to a method and a tool unit for setting a punching gap for a punching or cutting machine.
  • the tool unit has a first tool and a second tool. When cutting or punching the two tools are moved relative to each other. A cutting edge on the first tool and a cutting edge on the second tool work together to cut or punch a workpiece, such as a foil. There may also be a plurality of first and / or second tools.
  • Such cutting or punching machines are known per se.
  • DE 30 12 486 C2 a punching machine, which is for punching flat objects made of web or sheet material.
  • the relative movement between the first tool and the second tool is generated there by a wedge drive.
  • a transverse movement of a wedge body transversely to the working direction of the punching tool leads, for example, to the movement of a lower tool in the working direction towards the upper tool or away from it.
  • the punching stroke is therefore carried out by the lower tool via a transverse movement of a wedge.
  • DE 544 605 describes a device for adjusting the height of a lower blade in a cutting machine. In the working direction, the position of the cutting blade can be adjusted via one or more spindles and a wedge adjustment.
  • the gap between the first and the second When first using the punching or cutting machine, the gap between the first and the second must be Tool to be adjusted. In addition, the two tools get during the operation of the punching or cutting machine at each stroke in contact with the material to be punched and worn down. This causes a punching or cutting gap between the first tool and the second tool to increase. Thus, the setting of the punching or cutting gap is necessary during initial startup and during operation. An exact gap width is of great importance especially for precision tools. If the gap is or becomes too large, the quality of the cut or punched edge on the workpiece decreases, eg a burr may form on the workpiece. Such burr formation is undesirable. For example, such a ridge when punching out foils for accumulators lead to short circuits between adjacent foils. Exceeding a maximum value of the gap width is therefore to be avoided.
  • the device has an adjustment mechanism with linear guide for a carriage.
  • a counter blade body is arranged, which cooperates with cutting blades on a rotor.
  • the linear guide for the carriage has a relative to the rotor axis inclined linear guide axis.
  • One out DE 30 12 486 C2 known punching device has a fixed head part and a relatively movable machine part, which can perform a lifting movement relative to the head part for performing the cutting or punching process.
  • This lifting movement is generated in that a wedge-shaped element is present and that the movable machine part is also wedge-shaped and the two parts are in contact with each other at their wedge surfaces.
  • the movable machine part can perform the required lifting movement relative to the fixed head part.
  • At least the second tool is elastically deformed by means for adjusting a deformation force, thereby setting the punching or cutting gap.
  • enlargement of the deformation force compensates at least partially for an enlargement of the die gap which has occurred due to wear.
  • the deformation force is aligned in particular transversely to the working direction and thus transversely to the direction of movement of the first or second tool.
  • the first tool can be acted upon by associated means with a deformation force to adjust the punching or cutting gap.
  • the embodiments below with regard to can be explained on the second tool can also be used for the first tool.
  • the deformation can be plastic or elastic.
  • the tool in question when setting the gap width in the context of initial commissioning, the tool in question can also be plastically deformed.
  • Such elastic or plastic deformation can be generated very easily, for example by means of clamping means, which clamp the second tool to a holding device.
  • the invention eliminates a complex processing of the second tool, in particular its cutting or punching edge to adjust the punching or cutting gap to the desired size. This allows a very accurate adjustment of the gap.
  • the deformation force is generated in that the second tool is pressed in a direction transverse to the working direction on the side facing away from the punching or cutting gap against a support surface and is.
  • At least one tensile and / or pressure means is present in the tool unit, which prevents the second tool from moving transversely away from the support surface.
  • the support surface and the co-operating tensile and / or pressure means causes a deformation of the second tool transversely to the working direction.
  • the support surface is inclined at an inclination angle inclined to the working direction. This provides a simple and accurate way to vary the punching or cutting gap by elastic or plastic deformation of the second tool.
  • the second tool has at least one support part which projects with a rear surface on the associated support surface the holding device for the second tool is supported.
  • the rear surface extends at the same inclination angle inclined to the working direction and thus parallel to the support surface.
  • the support surface and the back surface are preferably designed to be stepless and edgeless. They form, so to speak, a force transmission means which can transmit a force in the direction transverse to the working direction on the second tool in the direction of the punching or cutting gap.
  • the tension and / or pressure means may be formed by anchors or screws or similar means.
  • a pressure means also a stop surface may be present, against which the second tool rests on its side facing the punching or cutting gap.
  • the stop surface may in particular adjacent to the punching or cutting gap, for example, arranged in extension of the punching gap next to it.
  • the deformation force can also be generated by a force-generating unit which has, for example, electrical, mechanical, hydraulic or pneumatic means and can preferably be electrically controlled.
  • a force-generating unit which has, for example, electrical, mechanical, hydraulic or pneumatic means and can preferably be electrically controlled.
  • the force-generating unit may have a motor-spindle unit.
  • a plurality of second tools may be present, which together form a die tool.
  • the second tools can be at close range be arranged in particular of a few micrometers next to each other or touch without exercising a sufficiently large force for deformation force each other.
  • the first tool can engage in the space between the second tools enclosed by the die cutting edge.
  • the deformation force is changed in the method according to the invention in that the height of a second tool is at least partially reduced, namely at least one support part of the second tool.
  • the dimension of the second tool at the position with the smallest dimension between the support surface and the cutting edge can be increased transversely to the working direction.
  • the deformation force thereby increases, whereby the width of the punching or cutting gap changed and in particular reduced.
  • the second tool is preferably made of steel, ceramic, carbide or other depending on the material to be punched material.
  • At least one tool part having the cutting edge of the second tool is made of one of said materials and / or has a hardness that is greater than the hardness of the support part of the second tool.
  • the tool part can also be designed as a separate insert, which is firmly connected to the support part.
  • the area provided for changing the height of the second tool on the underside of the second tool may have a lower hardness than the cutting edge having tool part, so that a reduction in height, for example by grinding, can be done in a less hard area of the second tool.
  • FIG. 1 shows a punching machine 10 in a highly schematic representation.

  • a punching gap 23 is formed in each case.
  • the punching gap 23 In order to avoid loss of quality and, for example, burr formation on the workpiece 16 or the stamped-out mold 15, the punching gap 23 must not exceed a predetermined maximum width.
  • the punching gap 23 must be set exactly during initial startup of the punching machine. In the course of operation of the punching machine 10 also wear on at least a first tool 12 and / or the at least one second tool 13 occur, whereby the punching gap 23 can increase.
  • a means for adjusting the punching gap 23 is provided, by means of which at least one of the second tools 13 plastically or elastically deformed and thereby a change, in particular a reduction in the width of the respective punching gap 23 can be achieved.
  • all second tools 13 are deformable, but this need not necessarily be the case. In some applications, it may be sufficient to apply only a part of the second tools with a respective associated deformation force.
  • the second tools 13 are releasably attached to a holding device 27.
  • every second tool 13 has at least one support part 28 and, according to the example, two or three support parts 28.
  • the support members 28 are in the embodiment according to the figures 3 to 7 on the punching gap 23 and the cutting edge 21 opposite side and project transversely to the working direction A of the cutting edge 21 away.

  • clamping means 33 for example by screw, every second tool 13 in the working direction A is firmly clamped to the holding device 27.
  • the second tool 13 is clamped with its underside 31 against the support surface 32.
  • the clamping means 33 are preferably designed so that they do not absorb any force transversely to the working direction A.
  • At least one tensile and / or pressure means 36 which serves to counteract a movement of the second tool 13 away from the support surface 30 and thereby generate a deformation force F together with the support surface 30, is associated with the second tool 13 to be deformed.
  • FIG. 3 are shown schematically as screws 37 running tensile and / or pressure means 36 illustrated.
