Definitions

  • the invention relates to a method for providing at least two groups of bending tools for the production of workpieces from metal sheets, in particular by forming the metal sheets in one bending process.
  • the EP 1 925 374 B1 describes a bending apparatus for bending a workpiece using a pair of tools formed by a punch and a die.
  • the punch is mounted on an upper table and the die is mounted on a lower table.
  • the bending apparatus includes machining information determining means for determining bending sequences based on product information, and for determining tools and tool layouts for each of the bending sequences and working positions.
  • a tool management database accumulates the total number of actual bends of each tool, based on the specified work positions, tools and tool layouts. The determination of the actual bending operations is carried out by means of a tool usage number detection device with reference to the tool management database.
  • a display device serves to display a number of uses of a relevant predetermined tool. In this way, tools with approximately the same number of uses and therefore associated with approximately the same wear and tear can be put together to form a tool group.
  • a bending apparatus that includes upper and lower tables and performs bending on a workpiece by means of tools attached to the tables.
  • Tool disposition information is automatically determined based on product information by tool disposition information determination means.
  • the tools which are required for bending and are designed to be divided, are accommodated in a tool accommodation device.
  • the tools are exchanged between the tool housing device and the upper and lower tables by a tool exchange device.
  • the tool disposition information determination means is designed to automatically or manually determine tool disposition information based on product information.
  • the tool accommodating device is for accommodating a tool group of a plurality of isometrically divided tools.
  • the tool exchange device exchanges tool groups between the tool accommodation device and the upper and lower tables.
  • the bending apparatus has processing station forming means configured to divide a tool group transferred by the tool exchanging means from the tool accommodating means to the upper and lower tables into a plurality of tool sub-groups based on the tool disposition information from the tool disposition information determining means. By dividing the tool group into a large number of tool part groups, a large number of processing stations are formed on each of the tables.
  • the processing station forming apparatus includes a separator mounted on a backgauge body, the separator being shared between the tools mounted on the upper and lower tables.
  • the EP 2 143 507 A2 discloses a method for assembling split tools on a press brake provided with a bending station for assembling a plurality of split tools which can be accommodated in a tool receiving device. Furthermore, the bending press has a tool changing device which moves the divided tools between the tool receiving device and the bending station and attaches the divided tools to the bending station.
  • the US2018/056357 A1 discloses a manufacturing facility comprising at least one bending tool; at least one tool storage for several of the bending tools; a bending machine, with a machine frame and press beam as well as tool holders for the at least one bending tool arranged or formed on the press beam.
  • the production plant comprises a manipulation device, by means of which the bending tool is moved between the tool magazine and the bending machine, in particular its tool holders, by a displacement movement carried out by the manipulation device from a tool storage position located in the area of the tool store along a transport path into a machine operating position located in the area of the bending machine , wherein a first coupling element is arranged or formed on the manipulation device and a second coupling element is arranged or formed on the bending machine, and that the manipulation device couples the first coupling element of the manipulation device to the second coupling element of the bending machine when it is in one of the machine operating positions is and the manipulation device is positioned relatively stationary with respect to the bending machine and thus a reference position is set.
  • the object of the present invention is to provide a method by means of which existing tools can be used even more effectively and cost-effectively.
  • the productivity of manufacturing plants is also to be increased.
  • the advantage of the method steps selected here is that bending tools that are still in the tool store and are not currently required for the first bending machine can be combined to form a second or further bending tool group. Since the current location of each individual bending tool is always stored in the bending tool data memory, the bending tool disposition determining device can, based on the second product information for the planned execution of a bending process in the second bending machine, determine whether those bending tools are actually used to form the second bending tool group are still in the tool store or not. If it has been determined that all bending tools required to form a second interacting bending tool group are actually still in the tool store, the second bending tool group is assembled by removing the bending tools required for this from the tool store.
  • a procedure is advantageous in which the assembled second bending tool group is transported by means of the bending tool changing device from the at least one tool store to the second bending machine and arranged on it.
  • the downtimes of the at least one second bending machine can thus be minimized, since in this way a plurality of bending machines can be supplied with the bending tools each located in the tool store from at least one tool store.
  • a further advantageous procedure is characterized in that after the removal of the bending tools of the second bending tool group from the at least one Tool memory the current new locations of the removed bending tools of the second bending tool group are updated in the bending tool data memory. Due to the constantly updated locations of the removed bending tools from the tool store, it can always be checked and determined whether it is possible to put together another bending tool group or not.
  • a variant of the method is also advantageous in which at least one intermediate tool store is provided with the at least one tool store, in which at least one intermediate tool store those bending tools that belong to a bending tool group according to the bending tool disposition information are put together and made available for transport to one of the bending machines.
  • at least one intermediate tool store those bending tools that belong to a bending tool group according to the bending tool disposition information are put together and made available for transport to one of the bending machines.
  • Another procedure is characterized in that only those bending tools are selected by the bending tool disposition determination device and also removed from the at least one tool store, which bending tools are outside of the intended forming process of the sheet metal contained in the bending tool disposition information to form the workpiece to be produced in the first bending machine lie. It can thus be avoided that a continuation of the bending process in the first bending machine is no longer possible because at least one bending tool is missing. This also ensures or enables a bending tool change in the first bending machine. This can prevent production interruptions and unnecessary downtimes.
  • a procedure is advantageous in which the new location of each bending tool in the bending tool data memory is updated for those bending tools that are brought back from one of the bending machines using the bending tool changing device to the at least one tool store.
  • a further advantageous procedure is characterized in that the determination of the presence of the multiple bending tools required to form the second bending tool group is carried out immediately after the respective new locations in the bending tool data memory have been updated. It can thus be avoided that a database that is no longer up-to-date is accessed when compiling at least one further bending tool group.
  • a variant of the method is also advantageous in which the determination of the presence of the multiple bending tools required to form the second bending tool group is carried out during the transport of the first bending tool group to the first bending machine or immediately after the transport of the first bending tool group to the first bending machine. In this way, possible incorrect withdrawals can be safely avoided.
  • Another procedure is characterized in that the determination of the presence of the multiple bending tools required to form the second bending tool group is carried out at the same time during the forming process of the sheet metal into the workpiece to be produced. This ensures that current data can always be accessed.
  • a procedure is advantageous in which the transport movement of the bending tool changing device is carried out by its own drive means and/or manually. This means that the transport can either be automated or, if necessary, carried out manually.
  • the 1 shows a greatly simplified schematic of a production system 1, which is designed for the production of at least one workpiece from sheet metal.
  • the production of the at least one workpiece can be carried out by forming in what is known as a free bending process by means of die bending.
  • a free bending process by means of die bending.
  • the production plant 1 shown here comprises a first bending machine 2, at least one second bending machine 3, at least one tool store 4 and at least one bending tool changing device 5.
  • the first bending machine 2 comprises a machine frame (not designated in more detail) and arranged thereon a first upper press beam 6 and a first lower press beam 7.
  • One of the press beams 6, 7 is guided on it so that it can be adjusted relative to the machine frame.
  • the second bending machine 3 is also designed as a free bending machine or die bending machine and comprises a second upper press beam 8 and a second lower press beam 9.
  • the second press beams 8, 9 are also guided on it so that they can be adjusted relative to the machine frame of the second bending machine 3. Irrespective of this, however, it would also be possible for the bending machines 2, 3 not to be in the form of free bending machines or die bending machines, but rather as swivel bending machines.
  • the press bars 6, 7; 8, 9 to clamp the sheet metal to be formed between them and to fix it in a predetermined position for the bending process.
  • the press bars 6, 7; 8, 9 are referred to as clamping bars.
  • a separate bending unit must be provided for carrying out the bending process. This is intended to express the fact that the forming method can be carried out using the production plant 1 with the bending machines that are equipped for this purpose, with the bending processes that are different from one another.
  • the bending tool 10 comprises at least one punch or bending punch and at least one die, a matrix or a bending die interacting therewith.
  • the bending tools 10 have a different cross-sectional shape and/or different lengths or widths in the direction of their bending edge. The different lengths and widths serve to be able to match the bending length or bending edge to be formed by the bending tool 10 to the workpiece to be produced.
  • the respective cross-sectional shapes depend on the bending and/or space conditions in the workpiece to be manufactured. All the bending tools 10, in particular in the tool store 4, are shown only in a schematically simplified manner.
  • At least one bending tool group 14 or 15 that interacts with the bending process to be carried out is assembled and formed from the bending tools 10 in the tool store 4 .
  • the bending tools 10 that form at least one bending tool group 14 or 15 are selected and put together using a bending tool disposition determination device 11.
  • the bending tool disposition determination device 11 is designed to provide first bending tool disposition information to be determined based on a first piece of product information relating to the bending process to be carried out. However, at least one second piece of bending tool disposition information based on second product information is also determined by means of the bending tool disposition determination device 11 .
  • the first item of product information is intended for the first bending machine 2 and the second item of product information is intended for the second bending machine 3 .
  • a bending tool data memory 12 is also provided, which is in communication with the bending tool disposition determination device 11 . An exchange of information and/or an exchange of commands can thus take place or be carried out between these system components. Operating terminals or other input or control devices are not shown for the sake of clarity.
  • the bending tool changing device 5 can also be integrated into the communication link.
  • the term communication connection is understood to mean any technical possibility for communication.
  • the bending tool data memory 12 is designed to store the respective current location for each individual bending tool 10 of the production facility 1 .
  • location means the current whereabouts or the current position of each individual bending tool 10 .
  • the location can be, for example, the tool store 4, the first bending machine 2, the second bending machine 3 or the bending tool changing device 5.
  • the bending tool changing device 5 By means of the bending tool changing device 5, at least one interacting bending tool group 14, 15 can be transported between the tool store 4 and one of the bending machines 2, 3 and vice-versa.
  • the bending tool changing device 5 is shown here as a manipulator, but can also be formed by different devices.
  • the first bending tool group 14 comprising a plurality of bending tools 10 is assembled based on this bending tool disposition information and the bending tools 10 required for this are taken from the tool store 4. This can already be done, for example, by means of the bending tool changing device 5 or a provision device that interacts with it.
  • the transport from the tool store 4 to the first bending machine 2 takes place by means of the bending tool changing device 5. This is indicated by arrows.
  • the at least one first bending tool group 14 is arranged on the first press beam 6, 7 of the first bending machine 2 and is held in the appropriate position on these.
  • At least one bending process can then already be carried out in a known manner using the first bending machine 2 .
  • a clamping process takes place between the interacting bending tools, which can then be referred to as clamping tools.
  • a second group of bending tools 15 can be assembled from this remaining number of bending tools 10 if all the additionally required bending tools 10 are still available and be formed. In this way, for example, the second bending machine 3 can be equipped with the correspondingly required bending tools 10 for a bending process to be carried out by it.
  • the bending tool disposition determination device 11 determines the at least one second piece of bending tool disposition information based on the second product information. Since all bending tools 10 that are currently still in tool memory 4 are known in bending tool data memory 12, bending tool disposition determination device 11, in cooperation with bending tool data memory 12, can determine whether all bending tools 10 for forming the at least one second Bending tool group 15 are still available or not.
  • the determination of the presence of the multiple bending tools 10 required to form the second bending tool group 15 can be carried out, for example, immediately after the respective new locations in the bending tool data memory 12 have been updated. Regardless of this, the determination could also be carried out during the transport of the first group of bending tools 14 to the first bending machine 2 or immediately after the transport of the first group of bending tools 14 to the first bending machine 2 . However, it would also be possible to determine the presence of the multiple bending tools 10 required to form the second bending tool group 15 at the same time as the metal sheet is being formed into the workpiece to be produced.
  • the bending tools 10 are combined to form the second bending tool group 15 by removing the bending tools 10 intended for this purpose from the tool store 4 according to the bending tool disposition determination device 11 determined second bending tool disposition information.
  • the second bending tool group 15 can be transported from the tool store 4 to the second bending machine 3 by means of the bending tool changing device 5 . This is also indicated with arrows. To turn the current locations of the removed bending tools 10 of the second bending tool group 15 stored or stored in the bending tool data memory 12, the locations in the bending tool data memory 12 are to be updated. The updating can take place, for example, immediately after the bending tools 10 have been removed from the tool store 4 .
  • At least one intermediate tool store 13 can be provided at the at least one tool store 4 or in the area of the at least one tool store 4.
  • those bending tools 10 belonging to one of the bending tool groups 14, 15 can be put together according to the bending tool disposition information and made available for transport to one of the bending machines 2, 3.
  • the bending tool disposition determination device 11 10 In order to avoid the necessary or required bending tools 10 for forming a second bending tool group 15 for the further bending machine 3 being removed from the tool store 4 in the first bending machine 2 for a subsequent bending process to be carried out, only those bending tools are used by the bending tool disposition determination device 11 10 to be selected which lie outside the intended forming process of the sheet metal into the workpiece to be produced in the first bending machine 2 contained in the bending tool disposition information.
  • the bending tools 10 required for the bending process immediately following the first bending machine 2 may not be removed to form the second bending tool group 15 for the second bending machine 3, despite their presence in the tool store 4, and thus remain in the tool store 4.
  • bending tools 10 are returned from one of the bending machines 2, 3 to the at least one tool store 4 and/or one of the intermediate tool stores 13 using the bending tool changing device 5, the new location of each returned bending tool 10 is in the bending tool data store 12 to update.
