Definitions

  • the invention relates to a composite roller according to the preamble of patent claim 1.
  • a composite roller of this type is known from DE-A-1 602 096 and is also shown in FIG. 1.
  • a roller base body 1 made of low-alloy steel a cylindrical step 2 is excluded in the outer area, which forms a seat for a roller ring 3 made of a working material, in the present case made of a hard metal, usually compacted by powder metallurgy.
  • the roller ring 3 is fixed in its seat by an annular end part 4, usually made of the same material as the roller base.
  • the ring-shaped end part 4 is secured by nut screws 7 parallel to the roller axis, by means of which the roller base body 1 and the end part 4 are fixed against one another and thus the roller ring 3 is clamped in its seat between the roller base body 1 and the end part 4.
  • Such a roller is relatively expensive to manufacture and also disadvantageous in that special attention must be paid to the fact that the cohesion of the roller base body and roller ring does not loosen during operation.
  • the object of the invention is to provide a composite roller with a roller base body and a roller ring fixed therein, in which the connection between the roller base body and the roller ring is particularly strong and secure.
  • the bond strength of the roller body, roller ring and end part is particularly high in this way and with the same material of the end part and roller body between these parts practically in the range of the basic strength of the material.
  • roller base body 1 made of a low-alloy steel, for example 42CrMo4, in which a step 2, which is coaxial with the roller and is oriented with parallel or perpendicular surfaces to the roller axis, which serves as a receptacle for a correspondingly shaped roller ring 3, which serves as the working surface the roller gives the properties it requires.
  • the roller ring 3 consists of a hard metal, which is usually a powder-metallurgical product.
  • the stage 2 forming the receptacle for the roller ring 3 is continued in a further stage 5, which receives an annular end part 4 which encloses and fixes the roller ring 3 in the receptacle formed by the stage 2.
  • the end part 4 is preferably made of the same material as the roller base body 1.
  • the capsule 6 is removed, for example by machining, with which the finished roll is available, which is used in this form for rolling wire or tubes.
