Definitions

  • the invention relates to a method for using roller tires. Providing a barrel made of metal, and especially stainless steel.
  • Such drums usually consist of a predominantly cylindrical side wall, which has been closed off by means of convex wall walls, around which side wall two or more roller tires are arranged.
  • These roller tires usually have a flat outer surface on which the barrel can roll, while the side walls are designed for this with a lifting tool, e.g. a fork to be engaged.
  • These roller tires are connected to the side wall by means of two welded connections on both sides.
  • roller tires An important disadvantage of such roller tires is that the welded connections are not sufficiently strong, and can therefore be broken during the rough treatment to which such barrels are often exposed, so that the roller tires then gradually loosen and will separate completely in the long run .
  • the invention aims to provide a roller tire for such a barrel, which does not have this disadvantage.
  • the method according to the invention for arranging a roller tire on a metal barrel is characterized in that a ring-shaped closed roller tire with a trough or tubular profile is placed around the barrel, and that the barrel wall is then cold-deformed outwards, thereby almost clamping the roller tire.
  • This deformation is preferably such that the wall in the area there is adapted to the shape of the tire profile, so that an optimal clamping is obtained by means of a wall shape following this profile shape.
  • an annular tire is formed from a tube, which is held in place when the barrel wall is deformed in such an outer die that this tube is also cold-deformed, for example in such a way that at least one is used as a tread serving flat outer surface is obtained, while preferably also the transverse walls are made more or less flat, so that an approximately rectangular or square average shape is obtained.
  • the barrel wall is pressed outwards by means of an inner die to be pressed outward, which die is preferably designed in such a way that the barrel wall is given a somewhat undulating deformation which is adapted to the roller profile and can at least encompass its edge regions to some extent. If the wall and a tubular roller tire are deformed at the same time, the parts that join together are deformed together and uniformly.
  • the invention further relates to a barrel which is provided with a roller tire by means of this method.
  • a metal barrel of common shape which is made in particular of stainless steel, is shown in cross section.
  • This barrel mainly consists of a cylindrical side wall 1 with convex end walls 2 fastened thereon.
  • lugs 3 with a flanged end edge 4 are arranged in the extension of the side wall 1, the barrel being able to be placed on these edges 4.
  • a pin hole 5 provided in the middle of an end wall is then also protected against damage.
  • roller tires 6 with a flat outer surface 7 and flat side walls 8 are provided.
  • the surface 7 serves as a tread when rolling the barrel, while a lifting tool, e.g. a lifting fork with a cross wind 8 can be brought into engagement.
  • Fig. 2 shows two versions of roller tires, both of which have been obtained from a tubular profile, of which profile a closed ring is first formed, which fits around the wall 1 with some play. These pipes are then not shown on the outside in one provided die, and then the inner wall is deformed outwards by means of an expandable die.
  • the inner wall 9 of the tube then has the same shape as the adjoining part of the wall 1, so that a positive connection between the two walls is then obtained, which counteracts any displacement of the roller tire with respect to the barrel wall.
