Definitions

  • the invention relates to a tool assembly according to the preamble of claim 1.
  • Such tool assemblies are used, for example, as punching and bending tool assemblies, which are used for processing and the automatic production of bent parts.
  • Each tool unit has a drive device, by means of which the machining tools of the tool unit are driven.
  • the drive device is firmly attached to a housing of the tool assembly and a transmission device, for example a drive shaft or a drive pinion, penetrates the housing and transmits the driving force to the machining tools.
  • the invention has for its object to provide a tool assembly that can be varied in its dimensions and in terms of its required space in a simple manner and adaptable to given structural conditions.
  • the drive device in the form of a drive module at various points on the housing of the tool assembly. Since the drive device makes up a significant proportion of the required installation space of the tool unit, this variable attachment of a drive module makes it possible to adapt the dimensions and the required installation space of the tool unit in accordance with the existing structural conditions and thus to achieve optimal use of the available installation space.
  • the integration of the tool assembly into the given production facilities is done in this way simplified. In addition, a faulty
  • a drive device usually comprises a motor and a transmission
  • This provides a further improvement in the possibility of adapting the tool assembly to structural conditions, in particular with regard to the utilization of an existing installation space.
  • a pulse-controlled electric or hydraulic motor for the drive modules makes it possible to control all the motors by means of a central control unit by supplying the individual drive modules with control pulses in a desired time sequence.
  • a special feature is the pulse-controlled mode of operation of the tool assembly that this enables.
  • the tool unit executes a full work cycle in response to a pulse signal from a control unit, for example a production line, as a result of which a specific component which is required in the production line is available at predetermined times. After this work cycle has been carried out, the tool unit is in "stand-by" mode until a new pulse gives the trigger signal for another cycle.
  • the embodiment according to subclaim 6 makes it possible to mount the drive module without further components, for example special support or bearing structures, having to be provided.
  • the drive module is attached to the housing of the tool unit by means of an easily detachable connection.
  • Such a connection is advantageously designed as a screw or tension connection.
  • the removability of the component penetrating the housing of the tool assembly enables the dimensions of the tool assembly to be kept small and compact, since the protruding or protruding parts can be removed.
  • the arrangement of a large number of coupling points, which can optionally be moved with a drive module, makes it possible to arrange a plurality of drive modules simultaneously on a tool unit in such a way that these are connected in parallel. In this way, a greater driving force can be achieved, and since the driving force is introduced into the drive ring or the drive shaft at several points, the occurrence of voltage peaks and any damage that may occur as a result is avoided.
  • the housing For exact positioning of the drive module on the housing of the tool assembly and for guiding during a displacement or adjustment of the drive module, it is advantageous to provide the housing with guide grooves. These guide grooves can also simultaneously serve as bearings for clamp fasteners, by means of which the drive module is held on the housing of the tool assembly.
  • the interchangeability of the front panel according to subclaim 16 makes it possible to convert the tool assembly in a short time without the tool assembly having to stand idle or dead.
  • processing tools are arranged in a desired arrangement on an interchangeable front plate and precisely aligned. When this alignment is complete, the front panel mounted on the housing is removed and replaced with the removable front panel.
  • the dead time of the tool assembly is thus limited to a minimum, which significantly increases the economy of the tool assembly.
  • FIG. 1a shows a view of a tool assembly according to the invention
  • FIG. 1b shows a side view of the tool unit on the left side according to FIG. 1a
  • FIG. 2 shows the drive device in the form of a separate drive module
  • FIG. 3 shows the possibilities of coupling one or more drive modules to a tool unit
  • FIG. 4 shows a further arrangement option for a drive module
  • FIG. 5 shows a processing line which is formed by interconnecting a number of tool units.
  • a punching and bending tool assembly 20 is shown in FIGS. 1 a and 1 b, which is used, for example, for the automatic production of bent parts from wire, strip or such semi-finished products.
  • the punching and bending tool assembly 20 has a box-shaped housing 21 which extends essentially in a vertical plane.
  • the housing 21 is provided with a central drive point in the form of a central drive ring 23, which is indicated in the figures only by the dash-dotted pitch circle.
  • the drive ring 23 serves to simultaneously drive a plurality of drive pinions 25, which one processing tool is assigned to each.
  • the machining tools are arranged in a predetermined spatial association with one another on a preferably removable front plate 24 of the housing 21. The removability of the front panel 24 enables it to be quickly and easily replaced by another front panel on which the machining tools are arranged in a different, desired configuration, without the need for longer changeover times.
  • the processing tools can be bending tools 29, a cutting device 22 and / or a feed unit, such as a semi-finished product feed.
  • a semi-finished product feed is connected upstream of the tool assembly 20 and attached to it via flanges.
  • the drive ring 23 is driven by a drive device which is attached to the housing 21 of the punching and bending tool unit 20.
  • the drive device is arranged in a separate drive module 10, which is shown in FIG. 2.
  • the drive module 10 comprises a housing 14, in which a gear 12 is arranged, and a motor 11.
  • a stepper motor is preferably used as the motor 11.
  • a drive movement of the motor 11 is transmitted to a drive pinion 13 via the gear 12, which is preferably designed as a reduction gear.
  • the drive pinion 13, which is preferably detachably mounted on the housing 21 of the punching and bending tool assembly 20, engages with the drive ring 23 and penetrates it
  • Housing 21 of the punching and bending tool assembly 20 The drive module 10 is attached to the housing 21 of the punching and bending tool assembly 20 from the outside by means of a releasable connection, for example by means of a screw or a clamp connection.
  • the outer surfaces of the housing 21 of the punching and bending tool assembly 20 have guide grooves 28; Via which the connection between the drive module 10 and the punching and bending tool assembly 20 can be established and along which the drive module can be moved in a simple manner.
  • the housing 21 has a large number of possible coupling points on its surfaces, at each of which the drive pinion 13 can penetrate the housing 21 and engage the drive ring 23.
  • the drive module 10 is attached in the vicinity of a desired coupling point on the punching and bending tool assembly and brought into engagement with the drive ring 23.
  • the free coupling points, which are not occupied by a drive module 10, are preferably covered by a cover in order to prevent dirt and foreign bodies from penetrating into the punching and bending tool assembly 20.
  • FIG. 3 four coupling points are simultaneously occupied with one drive module 10 each, the drive modules 10 being connected in parallel and exerting a driving force on the drive ring 23. In this way, both a greater driving force and a uniform load distribution in the drive ring 23 can be achieved.
  • This figure illustrates the variety of options for connecting the drive to the tool module. The number and position of the drive modules can be varied in order to provide a desired drive power in the case of predetermined installation spaces. According to Figure 3, the drive modules 10 are on those
  • Outer surfaces of the housing 21 of the punching and bending tool unit 20 are arranged, which adjoin the front plate 24.
  • coupling points for example in the form of bores 27, are also provided on the front plate 24, into which a drive shaft (not shown) of the drive module 10 can be inserted.
  • An example of a drive module 10 arranged on the front plate 24 is shown in FIG.
  • FIG. 5 shows a processing line which consists of a large number of coupled tool assemblies 20 1 , 20 2 , 20 3 and 20 4 . These tool assemblies 20 1 , 20 2 , 20 3 and 20 4 can each be preceded by tool assemblies A and B, respectively, which are not described in more detail, so that a machining line adapted to the given framework conditions can be formed.
  • six drive modules 10 are arranged. The coupling points of the drive modules 10 with the tool units are chosen so that the smallest possible installation space is required for the processing line.
  • the invention thus creates a tool assembly that has at least one time-controlled tool that is driven by a drive device.
  • the drive device is arranged in a separate drive module and there are a large number of on the tool unit Coupling points are provided, which can optionally be assigned with a drive module.
  • the drive module can be fastened from the outside to the housing of the tool assembly and each coupling point is assigned a preferably removable transmission device which penetrates the housing of the tool assembly.
  • Unoccupied coupling points are preferably covered with a cover and, for precise positioning and for easier adjustment of the drive modules, the outer surfaces of the housing of the tool unit can be provided with guide grooves, via which the connection to the drive module can be established.
