Definitions

  • the invention relates to a method for operating a metal extrusion press a block loader for loading a block to be pressed into one Blockaufillon, which is associated with a die, wherein of the block at its the die facing end a head piece is separated.
  • Extrusion and tube presses of this type are well known and will either operated as direct or indirect presses, i. with during the pressing process mutually fixed die and transducer or with in the transducer penetrating, attached to the front end of the hollow-bored punch die.
  • the particular design depends, for example, on the materials and Weights of the feed. It can be full profiles, rods, ribbons, wires as well as tubes and hollow profiles made of various materials, e.g. Aluminum and Copper or corresponding alloys.
  • reshaping the Feed remains over a pressing residue, which is usually in front of the tool or the die, but possibly also behind the die, from the pressed product is separated, for which the sawing and shearing are in use (see DE-PS 553 782).
  • the invention has for its object to provide a generic method to avoid the mentioned disadvantages.
  • the invention is based on the finding that causal for the Product defects occur during heating of the blocks in the furnace from their Front side or on the front side forming oxide layer, which then in the finished product as disadvantageous inclusion finds again.
  • an advantageous mechanical separating cut (shearing, sawing) the loading of the block in the billet and thus before the insertion in the block loader takes place, including only a short header end of the block can be separated, can be the adverse oxide inclusions and to exclude faulty products.
  • This release agent can be like for decades to separate the Press rest - the rear end of the block can therefore not be detrimental to the product impact, because the press residue was always always separated - known Facilities are trained.
