Definitions
- the invention relates to a method for cutting an initial shaped body having a certain hardness or plasticity into a number of final shaped bodies by means of a wire-like cutting tool, which during the cutting process with respect to the initial shaped body has a feed movement and a cutting movement executes a direction at least approximately perpendicular to the feed movement, the feed and cutting movement defining the corresponding part plane of the starting shaped body between adjacent end shaped bodies.
- the starting molded body of the type mentioned above can be a cuboid block made of aerated concrete, a strand or lever made of plastic ceramic material or the like. act.
- the starting shaped body can have a full cross section or a hollow cross section.
- a wire-like cutting tool which has a length which is only so much greater than the initial shaped body to be cut that the two end sections of the wire-like cutting tool which are at a distance from one another can be fixed on associated shafts.
- Said shafts are driven in an oscillating manner so that the wire-like cutting tool performs a corresponding oscillating cutting movement.
- the amplitude of the oscillating cutting movement is smaller than the corresponding dimension of the starting shaped body in the direction corresponding to the cutting movement, so that most of the cut or waste material produced during cutting, that is to say in particular in the central region of the starting shaped body is not transported out of this.
- the invention has for its object to provide a method of the type mentioned, in which the above-described deficiencies are eliminated in a simple manner.
- This object is achieved according to the invention in a method of the type mentioned at the outset by using a wire-like cutting tool with a length which is several times greater than the dimension of the starting shaped body in the direction of the cutting movement, the wire-like cutting tool being used during the cutting process constant cutting speed is unwound from a first storage device and is wound onto a second storage device.
- a wire-like cutting tool is used in the method according to the invention, the length of which is greater than the product of the length of the starting shaped body in the feed direction of the cutting tool and the quotient of the cutting speed to the feed speed.
- the wire-like cutting tool during an average of the starting shaped body, i.e. is only used from the beginning to its end during the formation of a corresponding dividing plane of the starting shaped body between adjacent end shaped bodies.
- a clean cut through the original molded body, i.e. Clean cut surfaces on adjacent end moldings are achieved if, when carrying out the method according to the invention, the wire-like cutting tool is cleaned during the cutting process by means of at least one cleaning device.
- This at least one cleaning device can be a cleaning brush which performs a relative movement with respect to the wire-like cutting tool.
- the wire-like cutting tool is guided by means of guide devices provided in the vicinity of the starting shaped body.
- These guide devices can be rollers or roller pairs, on or between which the wire-like cutting tool lies in a defined manner.
- Said guide devices can also be formed by bodies through which guide holes extend through which the wire-like cutting tool is passed.
- the wire-like cutting tool used according to the invention can be a simple, smooth wire made of metal, of a suitable plastic material or the like.
- a wire-like cutting tool with cutting elements spaced apart from one another is used.
- the cutting elements can be elements separated from a wire-shaped carrier of the cutting tool, which are spaced apart from one another by means of spacer elements, or are fixed to the wire-shaped carrier at a spacing from one another. This fixation takes place, for example, by welding. It is also possible to simply form a wire-shaped carrier with corresponding flattenings, which then form the cutting elements.
- FIG. 1 shows a spatial representation of a cuboid-shaped starting shaped body drawn in sections, and a wire-like cutting tool for cutting the starting shaped body into a number of end shaped bodies
- Cutting tool with cutting elements spaced apart from one another by spacing elements
- FIG. 4 shows a second embodiment of a wire-like cutting tool with cutting elements spaced apart from one another.
- Fig. 1 shows in sections in a spatial representation a cuboid shaped starting body 10, which is bounded by end faces 12, of which only one is visible in this figure, side faces 14 and main faces 16.
- the starting molded body 10 is cut apart along cutting planes 18 with the aid of a wire-like cutting tool 20, the cutting planes 18 being oriented parallel to one another and to the two side surfaces 14.
- the starting molded body 10 is cut apart with a cutting tool or with the same wire-like cutting tool 20 along cutting planes 22 perpendicular to the dividing planes 18 and parallel to the two end faces 12, so that certain hardness and plasticity are obtained from the starting molded body 10 a corresponding number of end moldings 24 are formed, of which in FIG. 1 an end mold 24 is separated from the starting mold 10 and indicated at a distance.
- Each end molded body 24 has two opposing and mutually parallel end faces 26 and a lateral surface 28.
- the starting molded body 10 consists, for example, of a green aerated concrete, but it can also consist, for example, of green ceramic material, of a plastic material or of any other material of corresponding hardness or plasticity. It is also possible for the starting shaped body 10 to have, for example, fully cylindrical end faces 12 or hollow cylindrical end faces, that is to say it is tubular. To carry out a cut through the starting shaped body 10, for example along one of the cutting planes 18, the wire-like cutting tool 20 is moved in the corresponding cutting plane 18 in the direction of the arrow v2, ie at a feed rate v2.
- the wire-like cutting tool 20 is, for example, unwound from a first supply device 30 and wound onto a second supply device 32.
- the wire-like cutting tool 20 thus performs a cutting movement at the speed v1 in its longitudinal direction during its advance at the advance speed v2.
- the cutting speed v1 and the feed speed v2 of the wire-like cutting tool 20 thus, viewed vectorially, span the corresponding dividing plane 18.
- the cutting tool 20 is relatively adjusted with respect to the starting shaped body 10, after which a further cut is made along an adjacent second dividing plane 18.
- the wire-like cutting tool 20 is then unwound from the second storage device 32 and rewound onto the first storage device 30.
- a wire-like cutting tool with a length L (see FIG. 2) that is several times larger than the dimension b of the starting shaped body 10 in the direction of the cutting movement, i.e. in the direction of the arrow vl, the wire-like cutting tool 20 being unwound from the first supply device 30 at a constant cutting speed v1 during the cutting process and being simultaneously wound onto the second supply device 32.
- Cutting planes 18 to cut The same considerations apply to the cutting of the starting shaped body 10 along the parting planes 22.
- the cleaning devices 34 are e.g. formed as cleaning brushes which rest against the wire-like cutting tool and clean it in rotation when carrying out the method according to the invention.
- the guide devices 36 serve to position the wire-like cutting tool 20 in the interior of the starting shaped body 10 to be cut in a precisely defined manner and thereby to ensure exact cutting work.
- the wire-like cutting tool 20 with the storage devices 3o, 32 in a stationary manner and to move the starting shaped body 10 past the cutting tool 20 with the aid of a suitable device; It is understandableSERver ⁇ 'also possible to arrange the output orts ⁇ -shaped body 10 and fixed 20 to allow the cutting tool to perform the feed movement corresponding to the feed speed v2. It is also possible to combine the two movements to combine other.
- FIG. 3 shows sections of a design of the wire-like cutting tool 20, in which cutting elements 40 and spacing elements 42 are alternately provided on a wire-shaped carrier 38.
- FIG. 4 illustrates in sections a wire-like cutting tool 20, in which a wire-shaped carrier 38 is formed with spaced-apart flats 44, which form the cutting elements 40.
- a suitable metal, a suitable plastic material or the like can be used as the material for the wire-like cutting tool 20. apply.
