Definitions

  • the invention relates to a press with a locking device for press rams according to the generic term of Claim 1.
  • EP-0 314 975 B1 describes a prior art for this Problem described.
  • the subject of this document is a Locking device for the ram of a press, at which has several locking bars in the upper area of the up and down departing plunger are provided with fixed Interact with locking bolts in the head of the press.
  • Such Locking device must be very stable and expensive be built to down if necessary to receive or close the directional load of the press ram compensate.
  • the Locking device can be designed for this, i.e. the This changes the height of the locking rod compared to locking latch engaging on the side. This requires an additional control device to adapt to such Circumstances.
  • the present invention has over known devices the advantage that they are universal for presses with constant stroke, as well as for presses with stroke adjustment for the adjustment of the Ram position at different tool heights can be used.
  • the proposed solution achieves a perfect one Independence from the respective tool height to be set. With a central arrangement in the drive system z. B. one Large part stage press is also the locking of several rams function of a machine possible.
  • the proposal according to the invention makes it possible absolutely infinitely variable in relation to the tappet position To achieve tappet locking.
  • the core idea of the invention is it, the lock directly on the main drive shaft of the Perform press, eliminating all influences by the following setting parameters can be excluded.
  • By a floating locking system is not Change of position of the drive shaft required.
  • Another Advantage of the chosen arrangement is that only a part of the ram weight acts as a torque, whereby a appropriately favorable dimensioning is achieved.
  • the invention is exemplified on a large section press described.
  • Figure 1 shows a large section press 1.
  • the main assemblies are table 2 with the sliding table 3 carrying the tool.
  • the head piece 5 by anchor 6 with the table 2 connected to a rigid press frame.
  • the drive 7 is located in the head piece 5 Main drive shaft 8.
  • the drive 7 is above levers, gears and eccentric in operative connection with plunger 9 is exemplary the plunger 9 in the illustration 5 times, accordingly the number of forming stages required.
  • the plunger 9 are in Embodiment all driven by the drive 7 and carry the upper part of the tool, not shown.
  • the Ram 9 performs two different movements, namely as “Production axis” the actual working or forming stroke and as a "setup axis", it can be applied to the respective tool height can be set.
  • the workpieces through the individual forming stations transporting transfer is marked with 10.
  • the tappet locking device 11 an unintentional lowering of the ram when the press is at a standstill should avoid, is located on the main drive shaft 8.
  • FIG 2 is a portion of the main drive shaft 8 with the Tappet locking device 11 shown in more detail.
  • the function of the tappet lock is achieved in that the main drive shaft is held securely against rotation.
  • one with the main drive shaft 8 External teeth 13 provided socket 12 z. B. by means of a Tongue / groove device firmly connected.
  • the slide lock also includes a sliding or Guide bush 14 which is firmly connected to a shaped piece 15 is.
  • the fitting 15 has an inner diameter Internal teeth 16 and carries one on its upper part Positioning device 17 by their function ensures that when locking the assignment tooth and Gap is guaranteed. The function of this Positioning device 17 is described in more detail in FIG. 4.
  • Cylinder 18 is for this purpose with its Bottom part pivotable with the head piece 5 as a support connected, while the extendable piston rod with the Fitting 15 is also pivotally connected.
  • Figure 3 shows the function desired when the press is at a standstill of the locked plunger. This will lock achieved that after determining the correct allocation of the Internal teeth 16 with the external teeth 13 through the Positioning device 17, the piston of cylinder 18 is applied and this by extending his Piston rod engages the teeth.
  • FIG. 4 shows the positioning device 17 already mentioned shown.
  • Main drive shaft 8 carries the external teeth 13 provided socket 12.
  • the fitting 15 with internal teeth 16 is firmly connected to cylinder housings 19.
  • In the Cylinder housing 19 is the left piston 20 and the right piston 21.
  • the two pistons act on a support or support device 22 which is firmly connected to the head piece 5 is.
  • the task of the positioning device 17 is before the axial Moving the fitting 15, the correct allocation of To define teeth 13 and 16.
  • the fitting 15 is located in the unlocked state in the parking position, i.e. Piston 20 is retracted, piston 21 extended. Piston 20 is with low pressure is applied while the piston 21 is relieved. This results in connection with the stationary support 22 a rotational movement of the shaped piece 15 until Signal transmitter 23 the correct assignment, i.e. Tooth protrudes Gap reports.
  • Pistons 20 and 21 are depressurized and the entire Unit is locked by cylinder 18 shifted, as shown in Figure 3. Is the locked one Position reached, both pistons 20, 21 with little Pressurized and the oil volume behind both pistons locked up leak-free.
  • the main drive shaft In connection with support 22 the main drive shaft rotatably via the teeth 13, 16 held. If the plunger tries to move downwards to turn the main drive shaft 8 via the press drive, builds up by compression depending on the tappet position and thus Direction of rotation in one of the two piston housings, against the fitting 15 and thus also the drive shaft Twisting secures. A change in the position of the plunger is thus blocked.
  • pistons 20 and 21 are depressurized and Shaped piece 15 pushed out of the tooth engagement by cylinder 18. Then piston 21 is pressurized during Oil volume at the piston 20 escapes. This causes the fitting to pivot 15 back into the parking position.
  • Figure 5 and Figure 6 shows an embodiment variant for the Attachment to a free shaft end 37 is intended.
  • the principle of operation is as already shown and the description is limited to the different ones Construction details.
  • the "unlocked" function is shown in FIG. 5 to see, i.e. External teeth 13 and 16 internal teeth not engaged with each other.
  • the one with the fitting 15 ' connected cylinder 24 carries out the locking movement, wherein the piston rod 25 is held stationary.
  • the positioning device 17 is shown in FIG. 6. in the In contrast to FIG. 4, two external ones were now used Supports 26, 27 selected.
  • the rotation of the shaped piece 15 to generate a correct positioning of the toothing 13, 16 effects the cylinder unit 28.
  • This cylinder unit 28 consists of a piston 29, piston rods 30, 31, Cylinder chambers 32, 33 and cylinder covers 34, 35.
  • the Cylinder chamber 32 or 33 pressurized with pressure medium. Should the Positioning device 17 e.g. from dashed parking position 36 are pivoted into the locking position, so must in Cylinder chamber 32 pressure can be built up. It finds one Change in position of the piston 29 in the cylinder 28 instead. Since the Cylinder 28 is integrated in the molding 15 and thus also Swing piston 29 and piston rod 30, 31 along, the ends must the piston rods must be spherical.
  • both cylinder rooms are again 32, 33 pressurized and in operative connection with the stationary supports 26, 27, the entire system is blocked and the drive shaft 37 held in rotation.
  • the system also for machines with one Press rams can be used without restriction.
  • An alternative is a perforated disc with at least one Called locking cylinder. Through energy independent Force application such as the spring force can Locking also as a safety device in the event of a power failure Act.
  • the pivoting and blocking of the Positioning device with a drive Interposition of a gearbox may also occur can be activated via clutch.
