Definitions

  • the invention relates to hot forming apparatus for hot working and / or press hardening of workpieces according to the subject matter of claim 1 and to a method for hot forming and / or press hardening according to the subject matter of claim 10.
  • Hot forming devices for hot working or / and press hardening of workpieces are known and, for example in the DE 10 2007 047 314 A1 and in the EP 2 233 593 A2 described.
  • the cycle time of the individual stations should be approximately equal to avoid dead times and thus to achieve optimum workpiece throughput.
  • Hot forming devices in which workpieces are to be formed which, in addition to press-hardened regions, should also have ductile regions, require a considerably higher cycle time than the other stations if the workpiece in the tool cools down to such an extent that it no longer becomes distorted after removal from the mold suffers, thus forming a "bottleneck" in the technological process.
  • the object of the present invention is to specify an apparatus and a method for hot working or / and press hardening of workpieces which does not have the mentioned disadvantages.
  • the second tool also has a first tool section, which is provided for forming the hardened workpiece section, and has a second tool section, which is provided for forming the ductile workpiece section.
  • Particularly preferred embodiments of the hot forming device may have the advantage that the total cycle time required is divided between two essentially identical tools, so that a higher workpiece throughput compared to a forming station can be achieved with only one tool. Ideally, the workpiece throughput is doubled.
  • Another advantage is that due to the planned cooling in the tool no delay can occur.
  • the delay can occur when cooled outside the tool, especially for workpieces that are made of different materials, for example, with different coefficients of expansion, or have areas of different material thickness. Rework may be required to achieve high dimensional accuracy of the workpiece. In the treated in the proposed device workpiece no distortion occurs.
  • the first and second tool sections need not be contiguous. It can be provided, for example, that a first tool section is arranged between two second tool sections or vice versa.
  • so-called crumple zones which can absorb impact energy, can be formed by second tool sections with ductile formation in workpieces intended for installation in motor vehicles.
  • the setpoint temperature of the first tool in the first tool section is approximately 20 ° C. and in the second tool section 300 to 400 ° C.
  • the temperature specification "about 20 ° C" here means that it is the ambient temperature of the tool.
  • first and the second tool portion of the first tool are integrally formed.
  • the two workpiece sections are delimited from one another only by different setpoint temperatures.
  • first and the second tool section of the first tool are separated by an expansion joint.
  • a compensating element is arranged, which is separated by expansion joints of the first and the second tool portion.
  • the second tool has a first tool section, which is provided for forming the hardened workpiece section, and a second tool section, which is used to form the ductile workpiece section is provided has.
  • the two tool sections can be delimited analogously to the two tool sections of the first tool.
  • the setpoint temperature of the second tool in the first tool section is about 20 ° C and in the second tool section is 20 to 200 ° C. It may thus be provided, for example, that the setpoint temperature in the first tool section is 20 ° C and in the second tool section 200 ° C.
  • the cooling time of the second workpiece section, which is formed ductile, is thus further increased and shifted into the storage phase of the removed from the device workpiece.
  • the temperature specification "about 20 ° C" here means that it is the ambient temperature of the tool.
  • the forming stations may comprise additional devices for processing the workpieces, for example punching and trimming devices.
  • additional devices for example punching and trimming devices.
  • these devices are arranged in the second tool sections, in which the workpiece is formed ductile and / or in the first tool section of the first tool. If the additional devices act during hot working prior to press hardening, there will be no increased wear on the cutting elements of the devices.
  • an industrial robot is arranged, which is designed such that it removes a machined workpiece from the first forming station and stores in the second forming station for further processing.
  • the term "industrial robot” is understood here also transport devices that work, for example, with intermittently moving gripper bars or the like.
  • a control device In order to control the hot-forming device, a control device according to the invention is provided, the control device having inputs connected to temperature sensors arranged on the tool sections of the tools and having outlets connected to tempering devices cooperating with the tool sections of the tools.
  • the control device can have further inputs and outputs and, for example, also be provided for controlling further stations which are upstream and / or downstream of the hot-forming device.
  • the tempering device comprises a cooling circuit with cooling channels arranged in the tool sections of the tools, a heat exchanger and a coolant compressor.
  • the object of the invention is further achieved by a method according to claim 10.
  • the proposed method has the advantage that the cycle time corresponding to the cooling time, which is required for hot forming and / or press hardening in only one process step, is divided into two process steps with two cycle times, each individually shorter than the aforementioned cycle time. This achieves a higher workpiece throughput.
  • Another advantage of the proposed method is that due to the planned cooling in the tool no delay can occur.
  • the delay can occur during cooling outside the tool, in particular for workpieces that are made of different materials, for example, with different coefficients of expansion, or regions of different material thickness, occur and require rework to achieve a high dimensional accuracy of the workpiece. In the proposed method, this rework is not required.
  • the target temperature of the first tool in the first tool section is set to approximately 20 ° C. and in the second tool section is in the range from 300 to 400 ° C.
  • the temperature specification "about 20 ° C" here means that it is the ambient temperature of the tool.

  • first cooling time for forming the hardened workpiece section and that the sum of the first cooling time and the second cooling time for forming the ductile workpiece section is provided.
  • the cooling time of the second workpiece section is thus further increased, and the storage phase of the workpiece removed from the device is used for complete cooling.
