Definitions

  • Horizontal metal extrusion presses are preferably made with one a cylinder spar, a counter spar and connecting them, Usually provided four tie rods formed press frames.
  • The is essential for a low construction effort Training of the tie rods as guides for the transducer holder and the spar that runs in the press frame along the press axis are displaceable (EP-A-0 379 937, DE-PS 23 66 117). Through this direct guidance on the tie rods can be trained as a guide frame Save the base frame (DE-PS 644 174, DE-OS 2 003 244).
  • the transducer holder and also the barrel are supported often on support surfaces that are arranged at an angle, that they cut the press axis in their extension or run close to the press axis, i.e. on the press axis are oriented, so the central position of the transducer and of the ram due to thermal expansion Unaffected temperature changes.
  • the guides for those with one Transducer holder and base frame supporting the walking bar between the guides and the base frame supports arranged on the base frame can be adjusted horizontally across the press axis are and against which the guides are vertically adjustable are (DE-PS 644 174).
  • This arrangement of the actuators perpendicular to the support surfaces oriented on the press axis has the disadvantage that the adjustment is always in a vertical and a horizontal component, their compensation an offset of the abutting on the support surfaces Sliding shoes of the actuators transverse to the direction of movement of Sensor holder and spar required.
  • the actuation of the Actuators are primarily used when setting up the Extrusion press when the pickup holder and barrel are at rest are located, due to the friction between shoes and Support surfaces of the offset not or only incompletely and only in the event of a displacement of the transducer or the walking bar takes place, making it difficult to set up the extrusion press is.
  • the invention relates to metal extrusion presses of the latter, the preamble of claim 1 or 2 corresponding type from and it is based on the task, the adjustability of the Transducer holder and the walking beam to the leading tie rods to improve and facilitate. This task is accomplished by the Formation of the extrusion press with the characteristic features of claims 1 or 2 solved.
  • the length of the base strips can be such that the entire of the holder and the spar their displacement along the area covered by the press axis cover the tie rod, then using the adjusting means Slip shoes are provided on the horizontal and vertical active surfaces of the base strips lie against and on these slide along.
