Definitions

  • the invention relates to a drive unit for a modular machining center with various work modules, each of which is inevitably time-controlled tools, such as. B. punching / bending tools, feeds, welding stations, assembly units and the like.
  • Machining centers of this type are known and are particularly distinguished by the fact that the work modules can be used in an ultimate manner, which results in extremely economical possible uses.
  • the core element of such machining centers is conventionally a punching / bending tool unit which has a main drive in a base, by means of which a central drive wheel mounted above it in a separate housing part is driven, which drives a multiplicity of work units, such as bending slides, cutting punches, welding electrodes and others drives in a chronologically predetermined sequence.
  • Other neighboring work units, such as B. (semi-finished) feeds or presses derive their drive from this main drive, which regularly requires more or less extensive drive means in the area of the interfaces between the work units.
  • the invention is therefore based on the object of providing a drive unit for a modular machining center with various work modules, which can be integrated into the machining center in a space-saving and economical manner and which opens up the possibility of changing work modules quickly and safely without moving the modules laterally to have to.
  • the main drive of the machining center is integrated into a press.
  • this has the advantage that the maximum power of the drive is available where the greatest reserves of power are required.
  • the further work modules no longer require a separate drive, as a result of which the base of these work modules can be constructed not only more simply, but with a unit grid dimension.
  • the base can also be used for storage and transport purposes, which greatly simplifies the replacement of the work modules and shortens the time required for this.
  • the base, together with the module housing resting on it, can be grasped and handled by means of a fork-lift truck, the recesses on the base providing a favorable weight distribution contribution.
  • the sequence of connecting the various work modules in series no longer has any effect on the set-up times when converting the machining center, because due to the unit pitch, the base is separated and decoupled from the other modules the module, any work module can replace the work module to be replaced.
  • This has the additional advantage that the output gear of the press can be stopped in a precisely defined rotational position with little effort, which greatly simplifies the coupling of the adjacent work module which is to be operated synchronously with the press. Because the press has precisely defined upper and lower dead center positions of the press ram, which tion of the driven gear can be used.
  • the adjacent work modules are equipped with locking devices with which the zero position of the tools relative to one another on the work modules in question when uncoupled can also be maintained during transport.
  • the bases of the work modules preferably have the same height as the base of the gear housing of the press.
  • Figure 1 is a side view of a modular machining center with a first embodiment of the drive unit
  • FIG. 2 shows a view corresponding to FIG. 1 of a further embodiment of the drive unit to show two variants of the counter-cutting plate holder on the press;
  • FIG. 3 shows a schematic top view of a machining center with a different arrangement of the work modules
  • FIG 4 shows the detail "IV" in Figure 1;
  • FIG. 5 shows a schematic front view of a punching unit mounted on the press in two embodiments
  • Figure 6 is a sectional view according to VI-VI in
  • Figure 7 is a sectional view according to VII-VII in Figure 5.
  • reference number 2 denotes the base housing of a drive unit, which accommodates the main drive 4 of the machining center shown.
  • the machining center is modularly constructed from three working modules 6, 8 and 10, the working modules 6 and 8 functioning as punching / bending tool units and the working module 10 being designed as a press.
  • Each punching / bending tool unit 6, 8 carries a multiplicity of tools 12, which are designed, for example, as bending slides.
  • the tools 12 are inevitably controlled in time, that is to say they are actuated to one another in a fixed cycle, for which purpose a central drive ring 14 is used which meshes with corresponding pinions 16 of the tools.
  • the work modules 6, 8 do not require a separate, own drive.
  • the driving force is derived from the main drive 4 in the manner to be described in more detail below:
  • the main drive 4 is, for example, part of a press 10 which, in the exemplary embodiment shown, is designed as a twin press.
  • the drive force is directed upward via a chain hoist 18 into the area of a press stand 20 in which a main drive wheel 22, which is mounted essentially in the center, is mounted. From there, the drive force is transmitted via two coupling gears 30, 32 and intermediate gears 24 to the two eccentric shafts 26, 28 and to, via the coupling gears 30, 32 the drive connection of the adjacent work modules 6, 8 to the main drive designed as a press takes place.
  • each central drive ring 14 is assigned intermediate pinions 34, 36, which can be brought directly into engagement with the coupling gearwheels.
  • the gearing engagement takes place at the vertical interface planes E s between the neighboring work modules.
  • the housing bases 38, 40 are hollow on the inside and function exclusively as the basis for the actual work units 6, 8 located above them. This opens up the possibility of the housing base to be used as transport and positioning devices for the work units, so that the work unit 6, 8 in question can be removed together with the housing base in order to convert the machining center and can be replaced by another unit.
  • two bottom recesses 42, 44 and / or two central recesses 46, 48 are provided on the working units 6, 8, into which the forks of a means of transport, such as e.g. a forklift can intervene.
  • a means of transport such as e.g. a forklift
  • the recesses 46, 48 there are advantages with regard to the weight distribution, so that the transport speed can be increased.
  • the illustration according to FIG. 1 also shows that the housing bases 38, 40 and 2 are designed in a uniform grid, ie with the same width, so that the work modules can be exchanged without problems.
  • the modules 6, 8 also have a base height H s , which corresponds to the height of the base housing 2 of the press 10.
  • the pinions of the individual modules are at the same axis height H A as those of the press 10. This ensures with simple means that the new work module to be coupled automatically comes to the correct working height, thereby ensuring the alignment of the pinions with the simplest measures .
  • the housing can be fine-leveled by means of adjustable support feet 50.
  • the construction of the machining center according to the invention still allows the possibility of connecting further units, such as feeds 52, 54, to the work modules 6, 8 or to the press 10.
  • centering devices 56 are preferably provided, in which Sliding blocks can be used.
  • the detail "IV" according to FIG. 4 reveals that the housing stands of adjacent work modules each have recesses 58 in the area of the meshing gears, which are closed during operation of the machining center by cover plates, not shown, which can take over the function of the centering devices 56.
  • a plurality of quick-clamping locking devices 60 are preferably provided in the area of the interface levels, which can be actuated by means of a hand lever 62 which carries a nut 64.
  • the nut 64 engages with a tension bolt 66, which has a locking plate 68 at the end, which is received in a form-fitting manner and with play in an undercut groove 70 of the adjacent work module.
  • the concept of the modular machining center according to the invention thus relocates the central main drive to the point where the highest power capacity is primarily required.
  • this also gives rise to new, previously unusable options for flexible assembly and simple replacement of the work modules, which can also be equipped with a central drive ring that is advantageous with regard to power transmission and the favorable arrangement options of the tools.
  • the identical structure of all housing bases results in an automatic alignment of the reference levels in the various work modules.
  • a special fastening of the counter-cutting plate 74 on the press stand 20 is provided, which will be explained in more detail below with reference to FIGS. 2 and 5 to 7.
  • components which correspond to one another are provided with identical reference symbols, the elements of the embodiment according to FIG. 7 being given an apostrophe.
  • the press stand 20 carries a guide part 76 for the press bear 78 on the front side.
  • the guide part is U-shaped and has two legs 80 and 82 pointing downward, to which the counter-cutting plate 74 can be screwed directly.
  • the two legs 80 and 22 end in the cutting plane 72 and the counter-cutting plate 74 closes the two legs to form a closed frame, which results in a favorable flow of force from the cutting plate into the press stand.
  • the counter-cutting plate 74 is screwed directly onto the legs 80, 82 by means of screws 84, 86. If the counter-cutting plate should be reground, no additional precautions need to be taken to maintain the position of the cutting plane 72. This is fixed once and for all by the lower end faces of the legs 80, 82.
  • the design of the guide part 76, 76 ' also allows the use of conventional counter-cutting plates 74', which are supported on a press table 88 'with the aid of sliding blocks 90'.
  • the screwing between the press table and guide part 76 ' takes place with the interposition of spacer sleeves 92' and spacers 93 ', which are also to be worked off by the same amount during the finishing of the counter-cutting plate 74'.
  • the two variants of fastening the counter-cutting plates 74, 74 'to the press 10 are indicated in FIG. 2 on the basis of a somewhat modified embodiment of the machining center. Otherwise, the modular construction of the machining center essentially corresponds to that according to FIG. 1.
  • the driving force is transmitted from the main drive 4 to the main drive wheel 22 via a traction means 98, the drive of the press eccentric shafts again being effected via identical intermediate gears 100 , which are in meshing engagement with identically toothed coupling gearwheels, so that a synchronized drive of the tool units in the various work modules is ensured.
  • the meshing engagement of the coupling gears is also preferably in the region of the interface between the base housing 2 and the press stand 20, so that the two components are easily joined together.
  • the concept according to the invention permits the retrofitting of the machining center in such a way that a complete work module 6, 8 on one of the machining center set up remote location and if necessary is replaced by means of a roughly working transport device, such as a forklift.
  • the drive force transmission from the press to the work modules can take place via gearwheels which are arranged in the corner areas of the adjoining housing boxes.
  • a plurality of coupling gearwheels can also be provided for each interface level.
