Definitions

  • the invention relates to a press drive module and a method for providing a press series.
  • the plungers of large mechanical presses were usually connected by connecting rods to an eccentric drive, which in turn was driven by a drive motor and a flywheel at a relatively uniform speed. Because such drives impose certain limitations on the travel / time history of the plunger movement, efforts have been made to drive the plunger, for example, by means of a servomotor, with the path / time curve of the plunger motion then set relatively freely by the appropriate control of the servomotor could be.
  • the disclosed DE 41 09 796 C2 the drive of the plunger via a connecting rod and an eccentric, which is driven by a servomotor.
  • the servomotor can run forwards and backwards and can be specifically accelerated and decelerated.
  • the U.S. Patent No. 6,041,699 also discloses a ram drive a press by means of servo motor via toggle mechanism. To drive the toggle mechanism serve a fferspindelgetriebe and servomotors.
  • DE 43 19 289 A1 describes a press drive module for a press ram according to the preamble of claim 1 for generating a drive movement and a pressing force between a first output to be connected to a press frame and a second output connected to the press ram.
  • a first drive device which is connected to at least one of the at least two outputs, is characterized by a first force / displacement characteristic.
  • At least one second drive device connected to the other of the at least two outputs is characterized by a second force / displacement characteristic.
  • the force / displacement characteristics of the at least two drive devices are set differently.
  • the press drive module forms a structural unit with the press frame.
  • the one drive device is formed by a drive cylinder, which sits on a gear block and can perform a lifting movement of the press ram relative to the gear block.
  • the other drive device is formed by Verstellspindelantriebe which are rotatably mounted on the press frame and driven by motors which are associated with the press frame. This drive device moves the gear block together with the press ram in the stroke direction to adjust the distance between the press ram and the lower tool, for example, to adapt to different sized tools can.
  • US Pat. No. 6,708,609 B1 discloses a method for providing a press line comprising a plurality of presses of different pressing force, each with press drive modules for their press rams for generating a drive movement and a pressing force between a first output to be connected to a press frame and a second driven end connected to the press ram.
  • the press drive module has a first drive device, which is connected to at least one of the outputs and which is characterized by a first force / displacement characteristic.
  • DE 101 58 861 A1 describes a press drive module for a press ram for generating a drive movement and a pressing force between a first output to be connected to a press frame and a second output connected to the press ram.
  • a first drive device is connected to at least one of the at least two outputs and has a first force / displacement characteristic.
  • the first drive means is formed by a hollow shaft gear, a spindle and a spindle nut.
  • a second drive device which is connected at least to the other of the at least two outputs has a second force / displacement characteristic and is as a hydraulic piston-cylinder drive executed.
  • the two force / displacement characteristics of the at least two drive devices are set differently.
  • the press drive module forms a structural unit.
  • the press drive module according to the invention combines in itself two drive devices which have different force / displacement characteristics. This is preferably achieved by using different drive concepts.
  • drive concepts In order to can not only wide limits arbitrary path / time curves of the plunger movement can be achieved but it is also possible to use for each part of the path / time curve respectively that drive device having the just fitting characteristic.
  • a weak but rather fast drive can be used for the passage of characteristic sections, which only require a small actuating force.
  • forming operations which are usually speedy but still relatively slow to perform but with high power that drive device can be used, which applies a relatively high operating force at a relatively low speed.
  • the two drive means united in the press drive module e.g. be formed by servomotors with downstream transmission and different transmission ratios.
  • the servomotors can be the same or different. Due to the different reduction, the servomotors work, although act on the same output, at one and the same output speed in different characteristic areas, which increases the overall design freedom in terms of achievable path / time profiles of the plunger movement. In addition, the scope is increased in terms of achievable forces.
  • press drive module is thus versatile and can serve as a basis for the equipment of different sizes presses of a press series. On the one hand, a large range of desired forces and driving speeds can be achieved with the given press drive module be achieved.
  • the press drive modules if the non-constructive or other Praktikabilticiansberichte, be connected in parallel in principle any number.
  • a press ram can be driven by one or more identical press drive modules, which can be provided within a press series of different performance classes. It is also possible to provide drive modules in different power classes, with the drive modules being consistent within each power class.
  • a press line can be constructed, the first stage (drawing stage) has a larger number of press drive modules while the subsequent, usually less loaded, press stages are equipped with correspondingly fewer press drive modules.
  • the individual stages of the press line different ram-way / ZeitVerpar and different ram strokes can be driven.
  • the performance classes of the provided press drive modules having a uniform maximum lift are exponentially stepped.
  • the power classes of the drive modules are determined, for example, by the maximum forces to be applied by the drive modules.
  • the Drive modules of different power classes preferably on the same maximum stroke. This allows the combination of press drive modules of different power classes with each other for the common drive of a plunger of a press.
  • the press drive modules of the different performance classes preferably have the same maximum travel speeds. This facilitates as well as the uniformly fixed maximum stroke, the parallel arrangement for common drive one and the same plunger.
  • the press drive modules each form structural units, which are formed separately from the press. They can thus be prefabricated and installed as a finished assembly in appropriately prepared press racks.
  • the assembly of the press drive modules can be separated from the assembly of the press frame. This is especially important for large presses. With this concept, a manufacturing simplification can go hand in hand and the construction time of presses can be shortened.
  • At least one of the drive means of the press drive modules includes a variable ratio transmission.
  • This may be, for example, a toggle mechanism, an eccentric, a combination thereof or any other transmission with variable ratio.
  • gearboxes come into question, which deliver in their dead or reversal point an infinitely large force transmission or in other words a fixed support point by the force to be sustained is no longer determined by the driving servo motor but only by the load limits of the transmission.
  • a servo-driven eccentric drive can be connected in series with a hydraulic cylinder. While the eccentric drive then serves to drive the ram in areas of its movement curve with relatively little force quickly, the hydraulic drive means can be used to drive the ram for workpiece deformation slowly with great force. If the eccentric is in dead center, the servomotor remains substantially free of forces. It is thus possible with relatively weak servomotors and a relatively short-stroke hydraulic device on the one hand to produce a large movement stroke for the plunger and on the other hand, a high forming force.
  • both drive devices can be activated overlapping.
  • these are preferably each common activated, complementing each other in terms of their power development.
  • the press drive module has its own base frame, which takes over the leadership between the two drives. It may further be provided a housing in which the at least two drive means are housed. Alternatively, however, it is also possible to integrate the press drive module at least partially into the press frame. For example, one of the power take-offs may be formed as part of a press header or plunger.
  • the press drive modules is preferably associated with an energy store, for example a mechanical, electrical or hydraulic energy store. This minimizes the supply network load.
  • the press drive module can be executed in principle in a variety of ways. However, its characteristic feature in almost all embodiments is that the introduction of force from the at least two drive means belonging to the module takes place at the plunger and / or at the head piece at a common location.
  • the press drive modules provide a fixed numerical relationship between the number of first drive means and the number of second drive means. For example, if a plunger is merely driven by drive modules of a single power class, which each have, for example, a first drive device and a second drive device respectively, then the plunger drive is generally independent of the number of press drive modules as many first drive means as second drive means available.
  • press drive modules are used with e.g. a first drive means and two or more e.g. three second drive means designed and used for ram drive, here are in the example three times as much second drive means available as first drive means. If press drive modules of different power classes and with different ratios between the numbers of the first and the second drive means are used, these numerical ratios apply in groups for the press drive modules of the respectively considered performance class.
  • the drive means of the press drive module are preferably mechanically independent of each other, i. they can be controlled independently of each other.
  • the synchronization of their working movement or the coordination thereof is preferably carried out electrically.
  • the individual modules or even only their drive devices or drives can be selectively controlled depending on the design or optionally also switchable and / or force-controlled. They preferably allow a continuous adjustment of the plunger stroke during operation and a variation of the path / time characteristic of the plunger movement during operation.
  • Force sensors can be provided in order to avoid overloading, in particular in the case of drive modules or drive devices driven in a controlled manner.
  • the individual drive devices of a press drive module may be coupled together via coupling devices of arbitrarily controllable type or overrunning clutches.
  • the slow drive means can be decoupled from the high-speed, when a ram travel is to go through quickly. The slow drive is then coupled again when the fast drive has moved the plunger back to the Abkuppelstelle and a slower plunger movement a large force is required.

  • the traversed by the plunger 7 path / time curve is similar, for example, a sine curve with much flattened lower shaft. While the upper part of this curve means a low-force opening and closing of the pressing tool 10, the lower part of the displacement / time curve refers to a small lifting portion above the bottom dead center of the plunger 7, where the actual material deformation takes place. For example, if the stroke is 500 mm, the force to be transmitted to the plunger 7 in the upper 400 mm is usually relatively small, while it may be greater in the lower 100 mm.
