Definitions

  • the invention relates to a stripping device for use with a Cutting tool with a cutting element, in particular a Punch, for processing a workpiece, in particular a sheet, wherein at least one attachment piece for attachment to the Cutting tool and a resilient element are provided.
  • Scraper devices are known in connection with various types of cutting tools (DE 196 05 113 A1, DE 40 35 938 A1, DE 42 35 972 A1 and WO 99/67038 A1). Such a stripping device is required in particular for punches or others cutting elements a stripping of the machined workpiece, in particular sheet metal, from the cutting element, in particular Punch to allow.
  • a front surface of the scraper lies against the Surface of the workpiece, springs during penetration of the Workpiece through the punch and when pulling back the Cutting tool out of the workpiece, so that Pull out the e.g. Hole punch ensured from the workpiece becomes.
  • wiper models are available on the market. The most have a mounting plate, by means of which they are attached to the Cutting tool, in particular a punch mounting plate, can be attached.
  • the wiper body is, for example, as Rubber spring made of a hard plastic, the front surface accordingly the workpiece contour is formed. The shaping can be done by Cropping done. The rubber spring surrounds the punch on all sides.
  • the shape of the front surface of the scraper is most Cases not symmetrical, since the workpiece to be machined is usually a has irregular shape.
  • the scraper also has that Task, the workpiece during the machining process in the desired shape. This is especially important if Punching should be made in the area of sheet metal edges, because due to the punching process, deformations can easily occur there.
  • the scraper should not independently deform the workpiece, but just keep it in the desired prefabricated form. If a punch is provided which completely encloses a punch Rubber spring wiper with an irregular front, to the sheet pointing design, this turns out to be problematic when the scraper around the punch after a few punching operations twisted. The surface shape of the scraper is then incorrect matches the surface shape of the sheet to be punched, which is why in this case there are quality problems and complaints can come.
  • the steel scraper has the punch on the workpiece to be machined surrounding element made of steel, the front surface of which is flat or is adapted to the shape, with a chamfered peripheral edge.
  • the one from that The other half of the scraper, which points the workpiece, consists of one Polyurethane spring. This provides an anti-rotation device for the punch formed that the punch in a partial area in cross section is constricted and rectangularly flattened. Intervenes in this area Section of the scraper, which by means of the steel scraper Screws is attached.

  • the arrangement of the resilient element outside of Workpiece contact area has various advantages. As a result, the resilient element does not constantly occur with oils and Greases in contact that gradually attack and destroy it. In addition, the contact of the workpiece with the stripping element instead of the resilient element essentially one Relentless contact area created that keeps the shape of the Workpiece allows and vice versa not deformed by the workpiece becomes.
  • the stripping element is therefore particularly preferably made of bronze or another adaptable to the workpiece surface shape Material that is strong enough to separate from the workpiece during the Not to deform the machining process.

This enables an even load, which reduces wear keeps the spring-elastic element as low as possible. Besides, will a defined position of the resilient element is established, And at any time, it can be easily replaced if it wears out is possible.
  • the resilient element is preferably the cutting element centrally arranged resiliently arranged. This is advantageous uneven wear of the resilient element avoided. In addition, especially in the case of an exchange given reproducible position of the resilient element, so that an exchange can take place quickly and easily.
  • At least one guide sleeve is preferred as a guide element outside of the stripping element, at least partially surrounding it arranged and / or is at least one guide bush as Guide element within the stripping element this leading arranged.
  • a guide element guidance of the Scraper element created what a defined movement of the Scraper element along the cutting element, in particular Punch, enables.

It turns out on the basis of poor access to the lubrication points and the otherwise long Lifespan of the stripping device but as advantageous.
  • the guide element is preferably in one piece with the fastening piece trained or are guide element and mounting piece as elements that can be joined together.
  • a one-piece training is suitable especially with higher forces, because in this case a unintentional tilting of the guide element and fastening piece must not be feared in each other. The stability and compactness the scraper is increased.
  • it is suitable Forming the guide element and fastening piece as an assembly Elements especially with lower forces. This can advantageous in particular also only one attachment with only one Fasteners, in particular a screw, can be selected.
  • the Fastening piece can be smaller and therefore more space-saving be formed.
  • At least one area is particularly preferred and / or the above section, in particular a claw or clip-shaped section, on the circumference or edge of the fastening piece for gripping a fastening device of the cutting tool intended.
  • the mounting piece on the Fastening device in particular a fastening plate, be centered. Secure and centered attachment or Locking the stripping device on the cutting tool or its Fastening device is also by only one Fasteners, especially a screw, possible.
  • An anti-rotation device is preferably used to substantially prevent it a twisting of the stripping element, in particular an elongated hole or Polygonal hole and / or an irregularly shaped cross section Wiping element provided.
  • an elongated hole or Polygon hole and / or an irregularly shaped in cross section Wiping element is given a clear position during installation, so that on its front surface according to the workpiece contour shaped scraper not accidentally twisted in position can be installed.
  • faster assembly is possible because the exact position of the stripping element can not be determined must, but by the shape of the stripping element and Guide element, preferably the guide sleeve or guide bushing, and the preferred provision of inner and outer guide surfaces on the Scraper element is specified. It will be faster, easier and more precise assembly of the stripping device on the cutting tool possible than this with the stripping devices of the prior art is possible.
  • the stripping device is particularly preferred together with a Wedge drive used, because with such a not only particularly high Forces can be transferred, but this is also particularly accurate must be done.
  • the anti-rotation device is in the range of hundredths of a millimeter.
  • Figure 1 shows a schematic diagram of a cutting tool 1 in the area of Details of a punch 2 with surrounding stripping device 3. Die Scraper device 3 is attached to a mounting plate 4 Mounting plate 5 of the punch attached. The mounting plate 5 is in turn mounted on the cutting tool 1.
