Definitions

  • the invention relates to a cutting tool for cutting a flat portion of a flat structure, in particular a thin-walled wall portion of a container, and for receiving the flat portion or the cut wall portion in the cutting tool.
  • Such cutting tools are known. They are e.g. used for opening cans or beverage cans. Usually this is done from a e.g. cylindrical canning or beverage can cut the end face by the cutting tool, wherein a part of the can wall is partially or completely cut out. If only partially cut out, the cut-out portion of the can wall can be bent into or out of the can to create a sufficiently large opening in the can.
  • the surface of the inner wall of the cylindrical cutting tool is a smooth, pure cylinder surface, it may occur in successively cutting out wall sections from identical cans that the cut-out part of the can wall clamps inside the cylinder, or that the cut-out part of the can from the inside of the cylinder and falls into the can.
  • the difference between falling out clipping and moderately jammed ie out of the cutting tool easily Removable cut only very small differences in the dimensions of the cut-out part and / or in the geometry of the receiving cylinder are responsible, so far no satisfactory results could be achieved with reproducible cutting and clamping the can wall cutout.
  • the invention has for its object to provide a cutting tool of the type described above, which works reproducibly and arise in the virtually no chips, in particular no metal chips.
  • the invention provides a cutting tool for cutting a flat portion of a sheet-like structure, in particular a thin-walled wall portion of a container, and for receiving the flat portion or the cut wall portion in the cutting tool.
  • the cutting tool is formed by a base body.
  • This main body has, at least in a partial region, a prism-shaped hollow body with a prism-shaped jacket wall whose end edge is shaped as a cutting edge which extends continuously along the entire circumferential direction of the prism-shaped hollow body and which surrounds the end opening of the hollow body.
  • the base body also has a connection region for connecting the base body to a drive means.
  • the front edge of the prism-shaped jacket wall which is shaped as a cutting edge has a course along the circumferential direction with different axial positions in the axial direction of the prism-shaped hollow body.
  • the cutting edge Front edge at least in two cutting edge peripheral regions each having a cutting edge along the axial direction cutting edge portion, on the inside of the prism-shaped outer wall surface has a recess adjacent to the respective projecting cutting edge portion of the cutting edge.
  • the projection of the cutting edge profile is directed to an axially orthogonal plane, such as a plane.
  • the plane of the planar structure a bulge or an "ear" on.
  • each with a recess adjacent to this cutting edge portion in the shell wall inner surface is obtained when cutting the portion of the sheet a section with two bulges.
  • the section in the interior of the hollow body clamps firmly to the prism-shaped jacket wall, which adjoins the projecting cutting edge sections.
  • the clamped over such bulges flat sections or wall sections clamp firmly enough to prevent their uncontrolled falling out of the prismatic hollow body. On the other hand, they do not clamp so hard that you have to exert very large impact forces for their ejection.
  • the cutting tool it is possible to start from a prism-shaped hollow body which forms the main body of the cutting tool. It is then possible in a first step of the end edge, which runs around the end opening of this hollow body, e.g. by grinding and sharpening, to impart a cutting edge course along the circumferential direction that has different axial positions, i. has axially projecting cutting edge portions along the axial direction of the prismatic hollow body. In a second step, the recesses can then be worked into the jacket wall inner surface in the areas of the protruding cutting edge sections. At the points where the recesses hit the cutting edge, bulges occur in the projection of the cutting edge profile. The two steps can also be performed in reverse order.
  • the grinding and sharpening takes place in a second step, wherein it ensures that the cutting edge produced crosses the recesses. In the places where the cutting edge crosses the recesses, bulges arise in the projection of the cutting edge course.
  • the cutting edge has at least in two circumferential regions in the axial direction in each case a projecting portion on which the shell wall inner surface along the axial direction to the cutting edge has an oblique course, wherein the measured from a longitudinal axis of the prismatic hollow body radial distance to the shell wall inner surface increases along the axial direction to the cutting edge.
  • the first bleed or puncture takes place at points that are based on the cut-out part of the container wall farther out. If the cutting edge now penetrates somewhat deeper into the container wall, the radial distance measured from the longitudinal axis of the penetrating prismatic hollow body to the casing wall inner surface decreases along the axial direction toward the cutting edge. This decrease in the radial distance between the cutting edge and the longitudinal axis of the prism-shaped hollow body takes place at least in two peripheral regions in which the axially projecting portions, so-called. Pre-cutter or tips are arranged.
  • the cutting tool according to the invention is suitable for cutting thin metal (sheet metal), in particular aluminum, and for cutting thin polymer material (foil, sheets, thin plates), in particular polyethylene terephthalate (PET), polybutylene terephthalate (PBT), cellulose-based material such as paper or cardboard , or starch-based materials such as flat-rolled or pressed foods.

  • thin polymer material foil, sheets, thin plates
  • PET polyethylene terephthalate
  • PBT polybutylene terephthalate
  • cellulose-based material such as paper or cardboard
  • starch-based materials such as flat-rolled or pressed foods.
  • the cutting tool is heated.
  • an optimum cutting tool temperature for cutting can then be set.
  • the jacket wall inner surface of the cutting tool only in the peripheral regions with the respective projecting cutting edge portions of the inclined edge to the cutting edge.
  • the oblique course of the shell wall inner surface may be formed by a flat ground or by a curved ground.
  • the jacket wall outer surface preferably also has an oblique course along the axial direction up to the cutting edge, wherein the radial distance measured from a longitudinal axis of the prismatic hollow body to the jacket wall outer surface decreases along the axial direction towards the cutting edge.
  • the peripheral regions are distributed uniformly with the axially protruding portions along the circumferential direction.
  • the prism-shaped hollow body may have a circular, an oval or a polygonal cross-section.
  • a cylindrical cutting tool with a circular cross section is particularly easy to produce.
  • the pits may be e.g. be prepared by grinding an annular groove on the cylindrical shell wall inner surface. Thereafter, the protrusions in the projection of the cut edge course can be made by crossing the previously prepared annular groove during grinding and sharpening of the cylinder wall end edge. Again, the order of the two steps can be reversed.
  • the prism-shaped shell wall at least in the region of its cutting edge made of steel, ceramic or tungsten carbide.
  • the axial length (b) of the area with the recess on the shell wall inner surface at the projecting portions is smaller than the maximum difference (a) of the various axial positions of the cutting edge along the circumferential direction.
  • the jacket wall inner surface of the prismatic hollow body has a microscopically rough surface and / or macroscopic elevations at least in an axial subregion of the inner surface.
  • the cutting tool has a plunger, which extends through a plunger opening of the base body and / or stored in this, and which is axially reciprocally movable inside the prism-shaped hollow body, so that contained in the interior of the hollow body cut wall portions of the hollow body can be ejected.
  • the cutting tool has an outlet opening in addition to the end opening, so that inside the prism-shaped hollow body previously recorded and optionally stacked cut wall sections can be ejected via later cut-out cut-out sections in the hollow body.
  • a suction device can also be connected to the outlet opening, so that cut-out wall sections contained in the interior of the hollow body can be sucked out of the hollow body.
  • the connecting portion of the cutting tool may include a handle.
  • the cutting tool may have a pincer-like or clip-like holding device, on whose first leg the base body having the cutting edge is fastened by means of its connection region, and on whose second leg of the thin wall portion having container can be fastened, so that by a relative movement of the two legs, the cutting edge can be pressed against the thin-walled wall portion and through it.
  • the prism-shaped hollow body can have an expanded cross-section in a partial region of its inner wall along its axial direction. In this axial region of the hollow body, cut-out portions can be loosely stacked, so that after a certain number of opening or cutting operations, the ejection of the accumulated in the cavity sections can be done without much effort.
