  • the invention relates to a method for producing metallic extruded products on extrusion and tube presses, which have a consisting of a cylinder spar and associated counter-spar press frame in which a movable, a block receiver bearing block pickup holder, which introduced a loader with a block to be pressed in Pressing position in front of the counter-spar spends with the local tool, and a movable stamping cross-member is provided, wherein in the cylinder spar a main or pressing cylinder is arranged, which receives in its cylinder housing at its front, supported by the stamping Traverse end provided with a plunger plunger, and in which the cylinder housing connected to a tank line is associated with an expansion tank supplying hydraulic oil to the plunger by means of a slide plate. Furthermore, the invention relates to extrusion and tube pressing or metal extrusion for performing the method.
  • the non-productive times must be minimized, in particular, the idler and the side of the cylinder associated with the Blockaufrichhalter, in which the block receiver or recipient is arranged, and the stamping cross member or strut associated idle and retreat with the highest possible speeds can handle.
  • the invention is therefore an object of the invention to provide a method and a strand and pipe press of the type mentioned without the disadvantages described, in particular, the hydraulic effort and reduce the non-productive time with a compact, simpler construction of the extrusion and tube press or metal extrusion press.
  • the electric motor drive is turned off and switched to hydraulic operation. This allows for the pressing of the loaded block to a strand required high forces for the plunger and for sealingly pressing the Blockaufrichhalters or Blockauf scenerys to the tool as well as for applying a stripping force to an end of the strand with a certain length or the Pressrest to be able to expose by removal of the Blockaufrichhalters for separation, also required high forces.
  • no hydraulics are used for the traversing movements, not only the required tank volume, instead of the previous approx. 10,000 liters now only approx. 400 liters, can be significantly reduced, but also a significant cost reduction of the hydraulics due to lower weights (approx.
  • the invention proposes that for clamping the loaded block between the ram and the tool of the block receiver holder and the stamp crosshead including plunger are simultaneously moved together and electromotively in the pressing direction, wherein from the expansion tank via an integrated in the master cylinder housing, open filling valve, a first Amount of hydraulic oil is pushed into the master cylinder behind the plunger, that after clamping of the block alone the Blockaufrichhalter is moved by an electric motor until the block traveled by the Blockaufillonhalter block is prise screeningt in Blockaufnado, whereupon then for pre-upsetting the block with the rear in the pressing direction of the Pressing piston connected, flanged to the rear wall of the expansion tank cylinder unit is acted upon, wherein a second amount of hydraulic oil via the open filling valve behind the plunger a is pushed out, and that the pressing of the block is carried out with a closed filling valve by applying pressure to the rear end of the plunger with hydraulic oil from a tank, accompanied by a third amount of hydraulic oil is expelled
  • the block picker holder is moved back hydraulically by a short distance corresponding to the pressing residual length for stripping the press residue.
  • the press residue protrudes from the billet and can be separated, usually by means of a press shear.
  • the block pickup holder and the stamping traverse with the plunger are moved back electromotively into the initial position for loading with a filling block to be pressed with the filling valve open.
  • the small pendulum volume thus returns to the expansion tank and is available again for a new pressing process.
