Definitions

  • the invention relates to a clamping clamp for mounting printing plates or the like on the work table of stamping presses, which can be used in a longitudinal slot of the work table used for holding, and a pivotable clamping arm with a first contact area which engages on the pressure plate or the like and one on a hydraulic actuating cylinder attacking second contact area.
  • a pressure plate or the like is usually mounted on the table of a stamp press by means of a hydraulic clamping clamp.
  • the tension clamp has a base that can be received in the T-shaped grooves formed in the work table of the stamp press.
  • the height of the tension clamps is fixed. Some have transmitted tension capabilities. In order to meet the height restriction of the pressure plate clamp, it is common to provide a corresponding clamping surface on the pressure plate or the like.
  • the clamps require positive hydraulic feed pressure to hold the pressure plate in place. The tension clamp must therefore be kept in a positive pressure condition in the tension condition. It would be useful if the usual tension clamps could be adjusted in height. This could avoid the need to provide a special clamping surface on the pressure plate to be held or the like. It would also be advantageous for the tension clamp if it were in the switched-off pressure would be effective.
  • Tension clamps of the type in question are known, for example, from brochures from Comatsu America Corp. (Greenfield Road, Southfield Michigan USA) and Optima * Spantechnik GmbH (Eiserfelderstrasse 300, Siegen FRG).
  • This object is achieved in that it has a supporting bolt with a foot section which can be inserted into the longitudinal slot and an upright shaft section on which the clamping arm is adjustably arranged such that its first contact area engages the pressure plate or the like in a generally over-centered manner
  • the hydraulic actuating cylinder has a contact surface with an essentially linearly adjustable one and is held at a distance from and in an aligned position with respect to the shaft section by means of a holder fixedly mounted on the shaft section of the supporting bolt.
  • the shaft section and the hydraulic cylinder are supported automatically and evenly in a parallel vertical arrangement by the holder.
  • the cylinder is expediently a cylinder which is under spring action in the switched-on state and is hydraulically released.
  • the clamping arm has two contact areas and is pivotally mounted on the bolt. The first contact surface or the first contact area cooperates with the piston of the cylinder during the second contact area is in contact with a pressure plate or the like.
  • the clamping arm advantageously has a substantially horizontally extending recess, which leads to a bore through which the threaded shaft section extends, onto which a washer resting on the recess bottom and an adjusting nut are applied within the recess. This makes assembly much easier.
  • the single figure shows the tension clamp in a side view, partly in a vertical section, and that in the tension-effective state.
  • the work table 11 of a conventional stamp press is indicated.
  • This work table contains a plurality of longitudinal T-shaped slots 13, only one of which is shown in the figure.
  • a support pin 19 has a generally corresponding T-shaped foot section 21 which is adapted to the slot 13 and is slidably received therein.
  • the shaft 23 of the support bolt 19 he extends generally perpendicularly from the slot 13.
  • a holder 27 is mounted on the shaft 23 of the support bolt 19 and extends over the table surface in order to receive a hydraulic cylinder 29 in the region of its other end. The holder holds the hydraulic cylinder 29 and the shaft 23 of the support bolt 19 in opposite, parallel alignment.
  • a clamp arm 31 includes a recess 31a which leads to a bore 37 extending generally perpendicularly through the arm.
  • the clamping arm 31 also has a first and a second contact surface 41 and 43, respectively.
  • the clamping arm 31 is mounted on the shaft 23 of the support bolt 19 so that the shaft 23 protrudes through the bore 39.
  • a washer 47 is placed on the bottom of the recess 31a around the shaft 23.
  • On this a nut 39 is screwed down on the shaft.
  • the contact surface 41 is formed by a recess or depression 51 which has a further depression 53.
  • This further recess is generally hemispherical in shape to receive the end portion 55 of the piston rod 57.
  • the end portion is generally hemispherical and is sized to fit the recess 53.
  • the recessed section 51 allows a limited angular orientation between the piston rod 57 and the clamping arm 31.
  • the contact surface 43 of the clamping arm 31 has a lower vertical position with respect to the surface 41.
  • the surface 43 is generally spherical in order to be able to interact with a clamped tool or a pressure plate 61 in a transferring effect.
  • the cylinder 29 is shown schematically in the figure as a cylinder of conventional design which is tensioned into the switch-on position by a spring and released by hydraulic pressure.
  • the cylinder 21 includes first and second chambers 71 and 73, respectively, which is divided by the base 75 of the cylinder rod 54.
  • the piston or base 75 is sealing with the cylinder wall Contact and receives the end of a spring 77 which extends through the second chamber.
  • the hydraulic fluid is fed into the first chamber 71 through a line 79.
  • the cylinder is only shown schematically in the drawing, and only for the purpose of illustration. The drawing does not reflect the actual design of such conventional cylinders.
