Definitions

  • the invention relates to a press as described in the preamble of claim 1.
  • Presses are common in modern manufacturing processes. For example, presses are used for joining (e.g., press-fitting bushings), severing (e.g., cutting sheet metal strips), master forming (e.g., pressing powders into bodies), and forming (e.g., bending or deep-drawing sheets). Even these few examples show how versatile presses are used in technology.
  • the shows DE 37 31 871 A1 a circulation rack, which is used in particular for storing upper and lower tools for a folding machine.
  • This has a arranged in the region of the side wall loading and unloading, which allows transfer of the tools from the circulation rack to the folding machine and vice versa by means of transfer bridges.
  • the JP 2220715 A also shows a magazine for storing the punch and die of a press brake, which can be arranged laterally thereof.
  • the punch and die are moved by means of a drive in and out of the press, so that a strenuous manual change can be omitted.
  • a disadvantage of the known methods for tool change is that only one tool must be removed from the machine before another can be introduced. This contradicts the requirement for the shortest possible set-up times.
  • the object of the invention is therefore an improved press, in particular one in which a tool change can be done faster.
  • the removal of a tool and feeding another tool can be done at the same time, because the tool no longer needed is pushed on one side from the tool holder in the tool transport rail and a new tool is on the other side of the Tool holder pushed from the tool transport rail into the tool holder.
  • set-up times can be significantly reduced.
  • the invention contributes significantly to the improvement of the prior art. The invention is therefore based on the insight that a simultaneous removal and feeding of a tool can significantly increase the productivity of a press.
  • a switch is arranged, which is connected to a tool feed rail which is open in particular at one end.
  • This tool feed rail serves to remove or supply tools from the annular tool transport rail. This is necessary, for example, when the tool transport rail is not long enough to accommodate all the tools that are necessary for the use of the press 1.
  • the tool feed rail can also be connected to a larger tool stock. It is then no longer necessarily open at one end.
  • first and / or second tool transport rail which are connected to a tool sub-rail.
  • This variant of the invention can be provided in order to increase the capacity of the annular tool transport rail or also to allow a re-sorting of the tools located in the tool transport rail.
  • a pivotable rail section is arranged in the first and / or second tool transport rail, which connects the first and / or second tool transport rail with a tool bearing. In this way, the capacity of the press for holding tools can be further increased.
  • a displaceable rail piece is arranged in the first and / or second tool transport rail, which connects the first and / or second tool transport rail with a tool bearing.
  • This variant also serves to increase the capacity of the press to accommodate tools. It is advantageous here that the displaceable rail piece can be straight and thus a smooth movement of the tools is guaranteed.
  • the training as described in claim 21 provides a simple structure for the equipment of the press bar with the necessary jigs.
  • Another advantage is an embodiment according to claim 22, whereby user-specific training of the press can be achieved. This is advantageous in that the tool transport rails can be arranged very space-saving in this way.
  • an embodiment according to claim 25 is advantageous because a simple design of the tool transport rail is achieved.
