Definitions

  • the invention relates to a frame press according to the preamble of claim 1.
  • Frame presses of this type are known (brochure frame press automatic machine Hydro Lux from Reinhold Hess GmbH & Co. KG in D-7460 Balingen, printed note HL11.91H2).
  • the press cylinders are guided so as to be adjustable by spindles in the longitudinal direction of the pressure beams.
  • the adjustment process itself is carried out by electric motors.
  • the spindles are precision threaded spindles that guarantee exact guidance. Similar devices can also be provided for the width settings if it is not sufficient to shift the pressure bars by hand.
  • the invention has for its object to simplify a frame press of the type mentioned in order to avoid in particular the expensive precision spindle drives or chain hoists.
  • the pressing corners and the pressure plates are delivered to the frame size by the same long-stroke cylinders, which then exert the required pressure after reaching the frame size.
  • the dimensions of the inserted frame legs, which form the frame dimension, serve as a stop for the initiation of the pressing process.
  • the cylinders of the long-stroke printing cylinders are attached in the lower area of the pressure beams.
  • a height-adjustable abutment is assigned to the lower region of the pressure beam, and a pressure plate aligned with the abutment is arranged at the free ends of the piston rods.
  • the pressure plates can be part of a guide head which is slidably guided between flat bars which are part of the pressure beam.
  • the pressure beams are formed by two flat bars running parallel and at a distance from one another, which are connected at the top and bottom and are provided with a guide carriage which allows the pressure beams to be pushed back and forth on the cross members of the support frame.
  • the flat bars can also be provided with transverse holes for fixing the height of the manually adjustable abutment. In this way, smaller frame dimensions can also be set in a simple manner.
  • at least one, preferably the outermost pressure beam can be assigned a long-stroke cylinder running perpendicular to it, the cylinder of which is attached to one of the side stands. In the same way, this measure allows the horizontal pressing of the press corners, as is possible in the vertical direction.
  • the printing plates are pendulum printing plates, so that frames which differ from the rectangular shape, for example for roof gable windows or the like, are then also formed. can be produced with the same frame press.
  • a frame press for example for the production of window frames is shown, which consists of a support frame (1) with two side stands (2) and each of an upper and a lower horizontally extending cross member (3 and 4).
  • On the cross members (3 and 4) are longitudinally displaceable pressure beams (5, 6 and 7) which are guided in a manner not shown, because known on the cross beam (3) and on the cross beam (4) by carriages (8) which engage in corresponding rails on the crossbeams (3 and 4) or directly in corresponding guide parts of the crossbeams (3 and 4).
  • the pressure bars (5, 6 and 7) each consist of two flat bars (9) arranged at a distance parallel to one another, which are connected to one another at the top by a cover plate (10) and at the bottom by a cover plate (11). Approximately in the middle of the flat iron (9) these are connected by an intermediate plate (12) in which the upper end of the cylinder (13) of a long-stroke train cylinder is fixed, the bottom of which is firmly connected to the lower cover plate (11).
  • both flat iron (9) are provided in the area of this cylinder (13) on the forward side with holes (14) in which lateral guide plates (15) height adjustable can be locked, which are also provided with holes (16). Locking bolts (not shown) can be inserted through these bores (16) and through the bores (14).
  • the guide plates (15) are arranged so that they can be guided on the outside of the flat iron. Its forwardly projecting end is screwed at the top to an abutment (17) designed as a plate, which, as will be explained later, is assigned to a pressure plate of the long-stroke train cylinder.
  • the two guide plates (15) are also connected on the end facing away from the abutment (17) by a transverse plate, so that there is an approximately U-shaped shoe for longitudinal guidance on the flat iron (9) for the abutment (17) the rear edge of the flat iron (9) is guided through the plate (18) and at the front through an upwardly projecting leg (19) of the abutment (15) and through guide rollers or through the shafts of tensioning screws (20).
  • the piston rod (21) protruding from the cylinder (13) of the long-stroke train cylinder at the top is connected at its upper free end to a guide head (22) which has two lateral guide plates (23) which are provided on the inside of the flat bars (9) Longitudinal grooves are guided.
  • the part of the guide plates (23) projecting forward from the flat iron is screwed at the bottom to a pressure plate (24) which interacts with the abutments mentioned above during the pressing process.
  • the pressure plate (24) is also assigned a downwardly projecting leg (25) on which the frame parts to be pressed can rest. It is immediately clear that when the pull cylinders are actuated, the pressure plates are pulled from top to bottom.
  • This process can be used both for adjusting the printing plates in the vertical direction and for pressing.
  • the pressing process starts at the moment when the pressure plate hits the transversely inserted frame leg when it is adjusted from top to bottom.
  • the new design therefore dispenses with the arrangement of adjusting spindles or additional drives.
  • the pressure plate (24) can be moved down to the position (24 ') when the piston rod (21) is retracted. Since, as previously mentioned, the abutment (17) can be moved manually into the position (17 ') by adjusting the bores (14), this results in an extremely small measure of the height of the frame which is pressed with the new device can be. However, the dimension can also be expanded to the maximum dimension shown in solid lines in FIG. 2.
  • Fig. 1 also shows that the pressure bar (7) on the right outside is connected to a horizontal long stroke cylinder (26), the cylinder of which is firmly connected to the left support (2) of the support frame (1).
  • Parallel to the long-stroke cable (26), another long-stroke cable (27) is arranged in the area of the upper crossbar (3), the piston rod of which is also connected to the right pressure beam (7).
  • the two cylinders of the long-stroke train cylinders (26 and 27) are connected to a common pressure source. If these cylinders are therefore actuated, the pressure bar (7) on the right can be moved to the left to the desired dimension.
  • the additional pressure bar (6) which can be moved manually in the exemplary embodiment, does not need to be actuated.
  • the pressure bar fixed at the left end is sufficient ( 5) and the adjustable pressure bar (7) the pressure plates (24) take place as previously described. Since the cylinders (13) of the pressure beams (5 and 7) - possibly also the pressure beam (6) - are connected to a common pressure source in this case, the pull cylinders are actuated simultaneously. On the other hand, there is also the guarantee that the forces exerted on all pressure beams are the same.
  • Fig. 4 shows a variant in that pressure plates are assigned to the three pressure bars (5, 6 and 7), which are designed as pendulum pressure plates (28). With this measure, non-rectangular frames can also be pressed. Since the pressure in all cylinders (13) is the same, the pressing takes place in this case also with uniform forces.
