Definitions

  • the invention relates to a press, in particular Fineblanking press, with one press top and one Upper press part assigned lower press part, where a tool between the upper press part and the lower press part located between an upper tool and the Press upper part and / or a lower tool and the Press lower part a hydraulic plate is arranged.
  • Presses come in a variety of shapes and designs on the Market.
  • a workpiece becomes a workpiece for example punched out of a workpiece strip and processed by the appropriate tool in the press, for example, beveled or the like.
  • the appropriate tool in the press for example, beveled or the like.
  • When editing the A variety of tool elements act on the workpiece together, each of which is usually under one certain pressure. According to the set Pressing interacts the tool elements Machining the workpiece instead.
  • a press of the above Kind is as hydraulic Deep-drawing device known from DE 43 43 336 A1.
  • the present invention has for its object a Press of the above To develop a way of building a Press and control in particular the activity of the Tools significantly simplified and very variable is designed.
  • top and bottom Hydraulic plate for additional hydraulic equipment are connected via installation supports.
  • the upper and lower hydraulic plates are one Unit connected, for example between a plunger and the Press lower part of the press can be used.
  • Means the installation supports are spaced from the top and lower hydraulic plate, so the hydraulic plates each separately on the ram or press lower part can be set. To remove the installation supports then only the ram needs a lifting movement through which the installation supports are released become.
  • a lower and an upper one To connect the tool plate to a tool package so that this tool package can also be handled as a unit.
  • This tool package is a unit between the two Brought hydraulic plates, clamped and by a Lift movement of the ram released the installation supports.
  • An existing tool can be used at any time or tool module against another tool package other tools can be replaced. Basically remains only the base frame and the lifting device for the Pestle always the same. All other parts of the press can exchanged and replaced by others.
  • the chosen hydraulic plate has the advantage that the entire hydraulic system for controlling the tool is no longer defined in the press itself, but separately from the actual press.
  • the hydraulic plate can exchanged at any time and for another Hydraulic plate with another hydraulic control be replaced. In the preferred embodiment even provided that the hydraulic plate always remains unchanged while the actual hydraulic Units inserted separately in the hydraulic plate and therefore can also be replaced separately.
  • the hydraulic Units exchanged and replaced by suitable units be replaced. Above all, it is also thought that in the hydraulic plate several hydraulic units can find space next to each other, so in a press several work steps are carried out in succession can. In this way it is possible to put a workpiece in this press, similar to a multi-tool or to process a multiple press. This will make the entire work processes significantly simplified and facilitated.
  • a hydraulic unit preferably has one Working cylinder in which a working piston is arranged is.
  • This working piston is under pressure corresponding printing medium or, for example, one mechanical spring, although a control and adjustable print medium is preferred.
  • Hydraulic oil is an option here, but in particular nitrogen should also be considered.
  • a plug-in tube is provided for supplying the pressure medium, which can be inserted into the hydraulic plate and a connection between, for example, a Hydraulic unit and the working cylinder.
  • the Hydraulic unit itself can in turn be mobile, so that it is independent of the press.
  • the structure of nitrogen is similar, outside of However, the plate contains nitrogen containers
  • a press P is schematic only with those Elements indicated for the present invention are important. This essentially includes one Ram 1 (press upper part) with which the press stroke is carried out. There is one on the plunger 1 Platen 2, which is also integrated Components of the plunger itself can be.
  • a table clamping surface 4 is embedded.
  • an insert 5 is provided, the one has central opening 6 through which a punched or finely cut product or punching waste can fall down.
  • the support brackets 7.1 and 7.2 rearranged and aligned in height so that a Tool package 13 between the upper hydraulic plate 9 and lower hydraulic plate 10 can be retracted.
  • the tool package 13 also rolls on the roller conveyors 8 the support bracket 7.1 and 7.2.
  • Upper tool plate 14 and a lower tool plate 15 are in turn by installation supports 16 from each other Cut.
  • Upper tool plate 14 is on the upper Hydraulic plate 9 and lower tool plate on the lower one Hydraulic plate 10 set, which in turn by the above.
  • Quick release devices can happen. Then the Press moved apart, i.e. the ram raised, see above that the installation supports 16 are released. Together working tools are indicated schematically at 17.
  • FIGS. 5 and 6 the detailed design of the Table clamping surface 4 and the lower hydraulic plate 10 recognizable.
  • the two sit on the table clamping surface 4 above mentioned stops 12.1 and 12.2. Between there are only two stops 12.1 and 12.2 schematically indicated thrust chain 18, with the additional hydraulic equipment Q via the table clamping surface 4 can be pulled.
  • the lower hydraulic plate rolls 10 on two roller conveyors 19.1 and 19.2, which are in the table clamping surface 4 and the openings 6.1 and 6.2 bridge.
  • European patent application 86 81 01 76.7 described T-strips into corresponding T-grooves 20 which lead to a later fixing the lower hydraulic plate 10 serve on the table clamping surface 4.
  • the lower hydraulic plate 10 is guided further by side guide rails 21.1 and 2.2, which on the table clamping surface 4 are arranged.
  • the upper hydraulic plate which is not shown in detail, looks similar to the lower hydraulic plate 10 however essential with regard to the positioning elements designed simpler. It only owns the four Holes for receiving the installation supports 11. Also points they have a rectangular recess corresponding to the Recess 24 in the corresponding upper hydraulic Units or nitrogen units are used. To these then in turn lead corresponding plug-in tubes. in the the alignment of the upper ones takes place Hydraulic plate 9 via these installation supports 11.
  • Figure 8 there are various possible arrangements of hydraulic units 26 or nitrogen units in the recess 24 in the upper and lower hydraulic plate 9 and 10, respectively.
  • Figure 8a there are only four units 26 used, in Figure 8b five units, in Figure 8c six Units and in Figure 8d seven units. Between can either fillers are used, which the support individual units 26 against each other or it can remain open spaces through which waste or punched products in the lower area of the machine get there and be led away. In this way creates a press with single or multi-stage tools. Any arrangement is possible.
  • This working cylinder 30th or working piston 31 become the inner tool functions the press or functions within the tool package 13, such as counter-holding during fineblanking, a denial, an expulsion, etc., taken over. This happens outside the actual tool package 13.
  • the working piston 31 can by compressed oil, compressed air, Nitrogen or operated by mechanical springs. In the preferred embodiment, pressure oil is used. This pressure oil passes through the plug-in tube 27 into the Working cylinder 30.
  • all plug-in tubes 27 are included Safety couplings 33 or safety membranes equipped, which in the unintentional release of a Hydraulic connection of the plug-in tube 27, for example Prevent hydraulic overpressure.
  • a corresponding one also belongs to the various units 26 mobile unit, via which the working cylinder 30 with Compressed oil, compressed air or nitrogen can be supplied.
