  • this device can be designed in such a way that the holding beam is provided with grooves for receiving and with fixing devices for fixing the supporting rods, the holding beam preferably having a plurality of parallel grooves.
  • the fixing device is an eccentric clamping device which consists of a pressure shaft which fixes the supporting rod in the groove and an actuating element which interacts with it.
  • each groove is penetrated by the pressure shaft, wherein, according to a development of the invention, each pressure shaft, based on its cross section, passes through the groove off-center.
  • the pressure shaft comprises, in its section passing through the groove, a fixing part which is formed in an extension of the shaft body and which is preferably a cylinder section, the cutting axis of which runs parallel to the direction of insertion of the pressure shaft in the holding beam and in the unfixed state outside the groove.
  • the pressure shaft has an engaging part in its area interacting with the actuating element, which is surrounded by a recess in the actuating element, the engaging part advantageously being provided within the shaft cross section.
  • the actuating element is driven hydraulically.
  • the angle of rotation is freely selectable and depends on the length of the stroke of the engaging part. This makes it easy to arrange support rods of different thicknesses in the grooves.
  • the pressure shafts assigned to each second groove are arranged in a row.
  • the actuating device can be a block rotatable about an axis with pressing tongs arranged on its circumference for receiving the filler rods and docking devices arranged between them for fixing the block in a press beam comprising the press drive, the dies proving ideal Press-in pliers are arranged on the rotatable block at a 120 ° distance, one press-in pliers each taking over a filler rod, the other press-in pliers in a waiting position, and the third press-in pliers pressing the filler rod with the supporting rods.

  • the filler rods 5 are taken from a spool of flat tape with a maximum weight of up to approx. 2.5 t or a ring.
  • a unwinding device is provided for the spool or the ring, with the aid of which the flat strip is transported into the straightening station 6.
  • the length of the filling rod 5 is determined and cut to length using a conventional tool.
  • the filling rod prepared in this way reaches the pressing station 3 via a transport path, in which it is taken over by the pressing tongs 7 of the actuating device 8 of the pressing station 3 after the longitudinal adjustment has been carried out.
  • the support rod 9 is also first fed via an unwinding device. It then passes through a straightening station, a slot press, in which the slots for the filler rods to be used are manufactured, and a cutting tool, in which it receives the correspondingly selected length. Then the pre-fabricated support rod is placed in a support rod magazine.
  • the support rods can be brought automatically or manually into the support rod magazine, from which the support rods are pushed into the support rod feed carriage 10 in cyclic operation, which brings the support rods into the pressing station 3. After pressing the support rods with the filler rods, the finished grate is taken over by the disposal handling and placed on a disposal belt 11.
  • the grate passes through this section into a station in which it is manually surrounded with an edge profile and then welded to the corners. Subsequently, the grate is pushed by a worker onto a conveyor roller conveyor, via which it reaches the welding station 4. In the welding station 4 the grate is positioned and tensioned and then optically scanned on one long side in order to determine the number of welding spots. After this process, the channel grate is welded to Mig-Mag. Four such welding stations are provided, the grate being rotated through 90 ° in each case via a turning station.
  • the finished press grate is brought into the stacking station, centered and stacked there. After reaching a predetermined stack height, the stack is automatically brought into the disposal position, from which it e.g. can be transported away with a forklift.
  • FIG. 2 shows the actuating device 8 of the pressing station 3 with pressing tongs 7 arranged thereon, which hold a filling rod 5.
  • the filler rods are guided in the longitudinal direction of the rotatable block 12, a series of press-in pliers 7 arranged one behind the other being provided.
  • FIG. 3 shows these press-in pliers in an enlarged view, a partial section providing an insight into the actuating device of these pliers, which are necessary in order to be able to hold a filling rod.
  • FIGS. 4 and 5 A section through the actuating device according to FIG. 2 is shown in FIGS. 4 and 5, the section according to FIG. 5 leading through the entire pressing station 3 and thus also showing the holding beam 13.
  • the support rod 9 provided with slots is arranged in the support rod holder 14 of the support beam 13. It is arranged in a groove 15.
  • the support rod holder 14 comprises a plurality of parallel grooves 15.
  • a hydraulically actuated eccentric tensioning lever is provided in order to be able to fix the support rods 9 arranged in the grooves appropriately during pressing.
  • the eccentric clamping lever comprises a pressure shaft 16 which fixes the holding rod 9 in the groove during the working cycle and which cooperates with a hydraulically actuatable actuating element 17.
  • the actuating elements 17 are mounted in the holding beam and are displaceable relative to the corresponding pressure shafts 16.
  • Each pressure shaft 16 is arranged at right angles to the associated actuating element 17 and engages with it in such a way that a displacement of the actuating element causes rotation of the contact pressure.
  • the pressure shaft 16 is provided with an engagement part 18 shown in FIG. 9, which interacts with a groove 19 of the actuating element 17 and is encompassed by the latter.
  • the engagement part 18 is part of the shaft cross section and is produced by two groove-shaped recesses in the shaft shaft. As a result, it is curved on its circumferential side and can be easily moved in the groove.
  • the pressure shafts passing through the grooves 15 of the support rod guide 14 are arranged in the holding beam 13 in such a way that the pressure waves passing through every second groove are arranged in a row.
  • This design creates two rows of pressure shafts.
  • the actuating elements 17 are also offset in the holding beam 13, in particular in order to create a dense, space-saving arrangement.

Subsequently, the second holding beam 13b takes over the fixing of the support rods 9, the first holding beam serves to guide the support rods. As previously described, the filler rods are pressed in in cycle mode. During the pressing and clocking process, the support rods are not released from their fixation. This takes place only after the last process. This ensures that the pressed grate leaves the pressing station at an angle.
  • the area of application of the press gratings produced according to the invention is varied; it can be gutter grilles, ventilation grilles, anti-glare grids or the like.

La grille est constituée d'une pluralité de barres de support (9) et de barres de remplissage (5) encastrables dans les barres de support. Tant les barres de support (9) que les barres de remplissage (5) sont amenées par des dispositifs d'amenée à une station de pressage (3) pourvu d'un dispositif de retenue des barres de support et un dispositif d'actionnement qui reçoit et presse les barres de remplissage à encastrer. Après le pressage des barres, le dispositif de retenue est avancé d'un pas librement sélectionnable et le dispositif d'actionnement est déplacé de sorte qu'une autre barre de remplissage soit déplacée d'une position d'amenée à une position de travail. Une fois que toutes les barres qui forment la grille ont été pressées, la grille est soumise à un traitement de finition.
