Definitions
- the invention relates to a method for producing cutting bodies with a base body and with a cutting layer containing hard materials, in which a metal powder mixture forming the later cutting layer and containing the hard material grains is melted onto the base body by means of a laser beam.
- Such a method for producing cutting surfaces based on hard materials, which contain diamond grains, for example, is described in DE 1 95 20 149 A1.
- a mold is used as a mold in connection with the base body that forms the bottom to form the desired cutting layer.
- the invention has for its object to make the production of cutting bodies with a cutting layer more cost-effective and efficient design with constant or improved usage properties of the producible cutting bodies.
- This object is achieved by designing the generic method according to the invention in such a way that a basic body blank is used which has at least one depression and the basic body blank with depressions is used as a mold for the cutting layer and the depressions of the basic body blank by continuously introducing and melting the metal powder mixture containing hard material by means of a laser beam in a coating process with the cutting layer up to the desired layer thickness and a blank for the cutting body is obtained and the desired cutting body is separated from the blank by cutting the same.
- an economical production method is thus proposed in which a large number of cutting bodies can be produced in a common production process and, moreover, the effort and the creation of molds are eliminated.
- the basic body blank for the cutting body is also designed as a mold.
- the latter When the cutting bodies are separated from the produced cutting body blank, the latter can be severed in the region of the basic body blank in order to obtain the cutting bodies.
- rotationally symmetrical rods or tubes can advantageously be used, which are designed with single or multiple threads with recesses in the form of radial annular grooves or with grooves or helical grooves running parallel to the longitudinal axis.
- basic body blanks in elongated shape, rod shape or tubular shape can be used, which are designed with a polygonal cross-section such as a square, hexagonal or oval cross-section and which are also designed as recesses with radial grooves or grooves running parallel to the longitudinal axis or helical grooves become.
- Basic body blanks in the form of a disk can also be used to produce cutting bodies, these being formed either on their end face or on a plane side with depressions such as grooves, which are subsequently filled with the cutting layer.
- a cylindrical basic body blank with a plurality of basic bodies for dimensions comprising cutting bodies is provided and in the basic body blank a number of radial annular grooves corresponding to the plurality of cutting bodies, which are spaced apart by intermediate webs , are incorporated and, in the case of a basic body blank rotating about its longitudinal axis, the grooves serving as the mold are filled up to the desired layer thickness with the cutting layer by continuous introduction and melting of the hard material-containing metal powder mixture by means of the laser beam and the cutting body blank obtained by means of Cutting through the basic body blank in the area of the removed intermediate webs, occasionally becomes the cutting bodies.
- an economical production method is thus proposed, in which a large number of cutting bodies in one common production process can be produced, ie parallel to each other.
- annular groove which is subsequently filled with the cutting layer, is the formation of the same with an undercut cross-section, and it can also be straight or spread, i. H. be funnel-shaped.
- the individual production steps for the simultaneous production of a plurality or a plurality of cutting bodies in one setting i. H. be carried out using a basic blank.
- a conventional lathe it can be assigned a laser processing head with a corresponding supply of the metal powder mixture containing hard material by means of a powder nozzle.
- Both solid bars or tubular ones, preferably thick-walled, can be used as the base body.
- Racks or disks with corresponding depressions can also be formed into cutting bodies according to the invention.
- the basic body blank can consist of steel as well as of a suitable tough plastic, such as polyamides, polyimides, polyurethane.
- metals or metal compounds or metal alloys containing hard materials are used for the cutting layers.
- the metal, the metal compound or the metal alloy is then by means of the laser beam when it hits the base body or the already existing layer or after it has been applied to the melted layer adhered melted. This creates a real alloy in the cutting layer.
- the laser beam melts the surface and at the same time the metallic powder grains that strike here, which results in the alloy composite.
- the thickness of the cutting layer that can be produced is usually between 1 and 7 mm. Examples of suitable metal components are iron, bronze, copper, tin, aluminum, titanium, silicon and others.
- Diamond grains are usually used as hard material, these usually having a size of less than 350 ⁇ m up to 1 exhibit.
- the diamond content in the cutting layer or powder layer can vary and can be up to a maximum of 99% by weight.
- the proportion of diamond grains also depends on the area of application and the shape of the cutting body.
- FIG. 1 shows a diamond saw cable in the cutout
- FIG. 2 schematically shows the production of the basic body blank
- Figure 3 shows the production of the cutting layer in a schematic
- Figure 4 shows the turning and separating the cutting body from the basic body blank in a schematic representation.
- a diamond saw rope see Figure 1 generally consists of a steel wire rope 1, on which the Rope beads or cutting body 2 are attached in the form of so-called diamond rings, which are held in position by spacers 3.
- the rope beads attached to the rope generally have a sleeve or ring-shaped base body 4 with a central bore which corresponds to the diameter of the steel wire rope used.
- the diamond-containing cutting layer 5 is located on the outside of the metallic base body. Today, the cutting layer is usually produced by powder metallurgy or electroplating.
- a method for producing the cutting bodies or rope beads is proposed, in which the individually listed manufacturing processes for a large number of rope beads are combined and each carried out in one setting.
- a base body blank 6 for example made of stainless steel, is clamped solidly or in tubular form into a conventional lathe, not shown here.
- the basic body blank 6 has a length such that a large number of rope beads or cutting bodies 2 can be produced from the basic body blank 6.
- grooves 7 are now evenly spaced apart from one another by left intermediate webs 9 by machining, for example by means of a shaping tool 8 during the rotation of the basic body blank 6.
- the grooves 7, which are used as filling grooves and, at the same time, with the basic body blank as molds, namely mold for the cutting layer to be produced, have, for. B. a concave shape, in particular an undercut shape, as can also be seen from the slightly wedge-shaped shaping tool 8.
- the grooves 7 are successively equipped with a cutting layer 5 containing hard material.
- the intermediate webs 9 are rotated freely between the grooves 7 filled with the cutting layer 5, for example by means of a further machining operation with a shaping tool 13, with the cutting body blank 2A rotating about its longitudinal axis X and in the same subsequent working step a parting tool 14 as a rope bead or cutting body 2 isolated.
- a further machining operation with a shaping tool 13
- the cutting body blank 2A rotating about its longitudinal axis X
- a parting tool 14 as a rope bead or cutting body 2 isolated.
- multiple tools can be used, so that, for. B. all machining operations or cutting operations can be carried out simultaneously.
