Definitions

  • the invention relates to a loading and discharge device for a press, in particular a hydraulic column press, consisting of a filling box which is open at the top and bottom and is displaceably arranged on a wear plate, the wear plate being arranged at the same level as the top of the mantle of the pressing tool and the front wall of the filling slide serves to eject the compact.
  • a hydraulic column press consisting of a filling box which is open at the top and bottom and is displaceably arranged on a wear plate, the wear plate being arranged at the same level as the top of the mantle of the pressing tool and the front wall of the filling slide serves to eject the compact.
  • the object of the invention is to provide a loading and discharge device in which, in the case of the above piston, there is no damage to the front wall of the filling slide or the piston when it is ejected.
  • a preferred embodiment of the invention is that the closure is a slide which is arranged vertically displaceably on the inside of the front wall. According to a further feature of the invention, the slide can be displaced vertically by a pneumatic, hydraulic or electromechanical device.
  • FIG. 1 shows an elevation, partly in section, of the charging and discharging device according to the invention
  • FIG. 2 shows a plan view of the charging and discharging device according to FIG. 1.
  • Fig. 1, 1 denotes a filling slide in the form of a box, which is open at the top and bottom and is slidably arranged on a wear plate 2.
  • a pneumatic or hydraulic cylinder 3 is provided for driving the filling slide 1 and is attached to the wear plate 2.
  • the wear plate 2 is fastened to the casing 4 of a press mold by means of connecting parts (not shown), the upper side of the wear plate 2 being level with the upper edge of the casing 4.
  • the front wall 5 of the fill slide directed towards the casing 4 is adapted to the shape of the compact 6.
  • the front wall 5 of the filling slide 1 ends at a distance above the welding plate 2, so that an opening 7 is created.
  • This opening 7 can be closed by a closure arranged on the inside of the front wall 5, which preferably consists of a slide 8.
  • a closure arranged on the inside of the front wall 5, which preferably consists of a slide 8.
  • At least one, preferably two, pneumatic or hydraulic cylinders 9 raise and lower the slide 8 and are fastened to the front wall 5.
  • the slide 8 can also be actuated electromechanically.
  • the casing 4, together with the loading and discharge device described above, can be displaced relative to the lower piston 10 of the press.
  • the filling slide 1 is secured against lateral movements by a straight guide (not shown).
  • the jacket 4 is raised and the filling material 11 is emptied, for example, from a silo into the filling slide 1, the opening 7 being closed by the slide 8.
  • the filling slide 1 is then moved to the right by the pneumatic or hydraulic cylinder 3 until the box-shaped opening of the filling slide comes to rest over the jacket 4 and the filling material 11 is emptied into the jacket 4. This process can be repeated several times as needed. If the jacket 4 is sufficiently filled, the filling slide 1 is shifted to the left and the actual pressing process, combined with other treatments of the filling material 11 in the pressing chamber, such as supply of solutions, heat treatment, pressing, etc., is initiated.
  • the jacket 4 is then lowered until the upper edge of the piston 10 protrudes beyond the edge of the jacket 4 and the compact 6 is exposed.
  • the slide 8 of the fill slide 1 is now raised so that the opening 7 is released, whereupon the pneumatic or hydraulic cylinder 3 moves the filling slide 1 to the right and the front wall 5 moves the compact 6 onto a slide plate 12, from where it is used for further use.
  • the distance between the lower edge of the front wall 5 and the lower edge of the open slide 8 to the upper edge of the casing 4 is selected so that neither the lower edge of the front wall 5 nor that of the slide 8 on the projecting piston 10 during the ejection movement of the filling slide 1 to the right streak.
  • the slide 8 can be equipped with a fault monitor which blocks the actuation of the pneumatic or hydraulic cylinder 3 if a fault occurs in the slide 8 and the latter does not open. This fault monitoring can be done by light barriers, microswitches, proximity switches or the like. respectively.
  • an actuatable flap can also be provided.
