Definitions

  • the invention relates to an interchangeable wear part, in particular a wear plate or wear shoe, for protecting components against abrasive removal, in particular in machine-technical facilities, such as, for example, woodworking and wood crushing machines and the like, or for at least partially armoring on walls exposed to abrasion.
  • a wear plate or wear shoe for protecting components against abrasive removal, in particular in machine-technical facilities, such as, for example, woodworking and wood crushing machines and the like, or for at least partially armoring on walls exposed to abrasion.
  • Wear parts or armor and the like have the purpose of preventing abrasion of components or machine parts from material removal or keeping them as low as possible in order to increase the service life of such parts and / or operational safety.
  • Wear elements are often used in machines in order to counteract a change in the geometric conditions by ablation, which can have a disruptive effect on the work functions.
  • Armor can be easily made by often welding wear-resistant filler metal to the component or machine part.
  • this has the disadvantage that distortion phenomena can occur due to the introduction of heat into the part, and a costly rework is usually required to smooth the surface.
  • the invention has for its object to provide an interchangeable wear part of the type mentioned, which has high wear resistance and durability, has low risk of breakage and is easy to attach with high stability.
  • This object is achieved in that the wearing part is formed from a base part made of tough material and a support part made of a material which has a high wear resistance, the base part and the support part being connected to one another in a flat manner and the base part having a fastening element by means of which the wear part is releasably attachable to the component.
  • the wearing part 1 shown in Fig. 1 is a plate-shaped element provided with a fastener, which consists of a support part 3 made of wear-resistant tool steel (e.g. DIN work number 1.20 ⁇ 80 ⁇ ) and a base part 2 made of a weldable structural steel consists.
  • the plate-shaped element was made of a composite material, for example Composite steel sheet worked out, this (s) from two material parts, which are metallically interconnected, existing plate or sheet with a thickness of 12 mm was produced by roll welding. A thermal treatment or hardening takes place with a view to the highest wear resistance and hardness of the support part 3.
  • the attachment of a fastening element 4 was carried out by arc welding or butt welding to form a weld or weld bead 5.
  • the fastening element 4 in the area of the connection 5 to the base part 2 can also be enlarged or have a larger diameter. This is preferably advantageous if larger bending stresses also occur.
  • the thickness of the base part 2 is equal to or greater than the thickness a of the support part 3.
  • the support part 3 can also be made of hard metal and cannot be removed from the base part 2 by soldering or the like be connected.
  • the support part 3 can be created by welding plating the base part 2.
  • Fig. 2 shows a wearing part 1 according to the invention and a conventional part 1 ', installed in a rotating ring of a cutting device. This ring equipped with knife 7 rotates in the direction R, with the cutting wooden parts being moved in the opposite direction.
  • the wear part 1 shown in area A according to the invention shows a uniform removal to a small extent from the surface 32 of the support part when producing wood chips 3.
  • a conventional wearing part 1 ' is shown, which has a threaded bore and is fastened to the ring part by means of a screw 4'.
  • a screw 4' In the case of abrasive stress, there is an increased removal of the materials in the area of the screw breakthrough and, furthermore, local scouring 9 of the wearing part 1 '.
  • the screw connection may also be loosened and / or knocked out, in particular due to an unsteady load under high stress, which means that it is often necessary to retighten the screws or to replace the wearing parts.
