    • B21C33/00—Feeding extrusion presses with metal to be extruded ; Loading the dummy block

Definitions

  • the invention relates to a working method for loading a press block by means of a block loader in the block receiver Metal extrusion press.
  • Metal extrusion presses for the production of profiles are known and for example in the company brochure of Mannesmann Demag Wegmaschinetechnik, "Extrusion press for aluminum profiles with controlled prestressing Press frame ".
  • These known metal extrusion presses a die arranged in the machine frame with the one to be pressed Profile cross-section on, as well as a firmly on the machine frame stored block loader, between which and the die a block receiver is provided.
  • the block loader is from a position to the side of the Machine frame pivotable into a loading position in which the transported press block can be inserted into the block receiver.
  • the loading process new press block can only start when the block pickup in the so-called pressure position is directly in front of the die. Since the Productivity of a metal extrusion press essentially from that Non-productive times of the press is influenced, i.e. the travel times of the Aggregates, the removal of the baling residue, the laying of new baling blocks or, a reduction in idle time would immediately result in a Increase production.
  • Block loading device Another block loading device, and a working method for loading a press block by means of this Block loading device in the block receiver of the metal extrusion press is from US-A-29 19 039 known.
  • the block loader is direct within the press attached to the block sensor holder and with a push-in lever equipped, which pushes the block into the block receiver.
  • the press ram can only be moved when the loader is swung out.
  • the aim of the present invention is a working method for quick charging a metal extrusion press to create with the total off-time is significantly reduced.
  • the particular advantage of the working method according to the invention is in that the loading process is independent of the block picker position and the sequence of movements can be carried out when removing the press residue, so that the individual parts of the system move at the same time Total non-productive times can be significantly reduced.
  • a metal extrusion press for performing the invention Working procedure with a matrix, a block pickup for the Press block, a block loading device, a press ram and one Shearing device for the baling residue is characterized in that the Block loading device coupled to the block sensor and with it is movable together in and against the pressing direction and that the Press ram at least the length of a press block from that Block picker can be positioned at a distance.
  • Block loader and Block pickers will be able to move the block loader towards to move its loading position while creating the block picker of the space between it and the die is retracted. As soon as the ram reaches the required distance from the block sensor the block loading device can be retracted or swiveled in to bring a new press block into the loading position.
  • the block loader is in the waiting position in swung out position, i.e. laterally offset to the block sensor 2.
  • a Press block 5 inserted into the receptacle of the block loader 1.
  • the block pickup 2 moves into a shear position (Photo b)), a position that has enough space between the die 4 and the block sensor 2 for the shearing process Press scissors creates. Processes simultaneously with the Block pickup 2 of the block loader 1 attached to the opposite of the Die retracted position. While block sensors and block loaders move, the ram 3 extends into its retracted position the block sensor.
  • the ram 3 can already be seen in the pressing direction in Movement displaces and pushes the press block 5 into the block receiver 2 a.
  • the block loader 1 swings into his Starting position back and the ram 3 moves the block 5 on into the block sensor while this and the stamp itself to move together on the die 4.
  • the die 4 on A new pressing process begins. Once this is completed, the work cycle is repeated again.
