Definitions

  • the invention relates to a hard metal or ceramic blank for drilling, milling or reaming tools with at least one internal flushing channel running helically in the longitudinal direction.
  • the invention further relates to a method for producing such a blank, wherein the hard metal or ceramic material is extruded through a nozzle of an extrusion tool and rotated helically, and each flushing channel is formed in the blank with a pin protruding into the nozzle.
  • the invention relates to an extrusion tool for producing such a blank or for carrying out the method mentioned.
  • a blank, a method and an extrusion tool of the type specified are known from European patent application 223 909.
  • the blank in the nozzle is rotated by helically extending grooves or webs, which causes considerable shear forces, especially in the area of the groove or web base, and cracks and loosening in the extruded material can occur. Due to uneven compression during sintering, locally different shrinkages occur, which increases dimensional inaccuracies and the risk of breakage.
  • the grooves and webs provided offer only poor dimensional accuracy or inaccurate further movement or twisting of the primary material, thereby reducing the work involved in reworking or the committee is enlarged.
  • grooves or webs represent locally limited discontinuities in the material distribution of the blank and have an unfavorable effect on the sintering properties of the blank;
  • the force transmission of the grooves or webs formed in the nozzle to the material mass is unfavorable because the force input into the mass for the twisting can only take place in the relatively small dimensins having grooves or webs and the friction of the mass on the remaining inner surface of the nozzle this force input counteracts.
  • the object of the invention is now to produce an extrusion green body or blank which has high accuracy of dimensions after sintering, has a homogeneous and high density, which reduces the risk of breakage and which can generally also be produced at room temperature.
  • the blank should have uniform shrinkage during sintering in order to ensure dimensional accuracy.
  • a blank of the type mentioned at the outset is characterized in that the blank has the cross-sectional shape of a polygon with at least two corners, preferably at least three corners, in particular with at least five or more corners, this polygon extending over the course of the length of the blank Axis of the blank occupies a particularly continuously rotated position or the surfaces running between the longitudinal edges of the blank are in particular continuously twisted.
  • Such a blank can be manufactured true to size and has a uniform shrinkage during the sintering process, since material irregularity in the blank mass is prevented by the rotational forces acting over its almost entire circumferential surface. The forces acting on all sides result in a homogeneous compression.
  • the blank is further processed in a simple manner, with only a relatively small number of protrusions being removed, since the edges of a polygon, in particular a regular polygon, only insignificantly match the inscribed circle of the polygon tower over.
  • edges of the polygon representing the cross section of the blank are at least partially straight or curved. It can further be provided that the corners of the polygon representing the cross section of the blank are each formed by two straight edges or edge pieces or by one (n) straight and one (m) curved edge or edge piece, or that the cross section of the Blank polygon is a regular polygon, preferably with more than four corners.
  • the polygon is a triangle with curved edge sections;
  • the polygon can also be given a polygonal shape corresponding to the desired extent of the object to be manufactured, provided that this polygon enables the extrusion material to be twisted sufficiently well.
  • a method of the type mentioned at the outset is characterized in that the extrusion material by sliding the extrusion material on helical or helical sliding surfaces formed on the inside of the nozzle and complementing a polygon in cross section around the longitudinal central axis of the blank or nozzle is set in rotation and is extruded with twisted outer surfaces, for example in the form of a twisted prism or parallelepiped, preferably at room temperature. It was found that, due to the improved rotatability of the extrusion material, processing of the extrusion materials can usually take place at room temperature and in many cases no elevated temperature has to be provided for extrusion.
  • the procedure according to the invention enables the pressure to be introduced over the entire circumference of the edges or the surfaces into the interior of the extruded material, which are advantageously straight in cross-section, as a result of which high tightness is achieved and Loosening or local leaks can be avoided.
  • the strand of material is guided and threatened with the aid of the entire surface of the nozzle, thereby avoiding unevenness due to unequal forces. It was also found that the entire nozzle can be made slim and allows a high extrusion speed, which ensures the economy of the process.
  • An extrusion tool according to the invention of the type mentioned at the outset is characterized in that the nozzle has on its inner wall surface a number of sliding surfaces which complement one another in cross section to form a polygon, which sliding surfaces have a profile twisted along the length of the nozzle.
  • the sliding surfaces of the nozzle form a straight, twisted, preferably regular prism, a straight, preferably regular, twisted parallelepiped or a straight twisted, preferably regular, truncated pyramid, possibly tapering towards the nozzle outlet.
  • At least one guide blade imparting a rotational movement to the extrusion material preferably a guide vane ring and / or guide vane. It was found that with such a design of the tool, the material distribution is homogenized or homogenized, and the formation of cracks and voids is largely avoided.
  • At least the region of the nozzle core close to the nozzle has a helical design with a polygonal cross section to support the rotation of the extrusion material.
  • This embodiment of the invention is particularly intended for materials that are difficult to extrude and delivered results.
  • the pin (s) for forming the rinsing channel (s) are usually attached to the nozzle core; According to the invention, the pins for forming the flushing channels can be fastened to the guide vanes or guide vanes, in particular if one dispenses with a nozzle core, which is readily possible in the case according to the invention, since the presence of a nozzle core is not absolutely necessary due to the rotational movement supported by the guide vanes is.
