Definitions

  • the present invention relates to a method and a device for assembling beaver double moldings after the basic shaping and before firing.
  • the present invention aims to create a new method and a new device which is not only very inexpensive but also extremely reliable and easily adjustable in order to take into account the wishes of the operator.
  • the cutting device for shape cutting of double beaver bricks has a frame 1 which is equipped with brackets 2 for fastening it.
  • a circular arc cutter 4 is arranged in the frame 1 at the exit end of the cutter, an outgoing molding 5 being shown in FIG. 2.
  • upper cutting pins 10 are arranged which are connected to a cutting rod 11.
  • This linkage 11 is connected via a pivot axis 12 to a cutting linkage 13 at the top, which in turn is pivotally coupled to the piston rod of an upper air cylinder 15.
  • the two upper cutting pins 10 are arranged in mirror image, as are the rods 11, 13 and air cylinders 15 which actuate them, their control being carried out centrally via a valve which in turn is controlled by an electronic control (not shown).
  • the circular arc cutter 4 is equipped with a piston-cylinder unit 22, the piston linkage 23 of which is connected via a bolt 25 to a swivel arm 24, the free end of which is clamped on a swivel shaft 26.
  • the pivot shaft 26 is rotatably mounted in two bearings 28, which bearings 28 are in turn connected to up and down supports 29. With the help of two fixed supports 30, a corresponding tensioning or loosening of the two chains 36 is made possible via a chain tensioning device 31.
  • an upper sprocket 32 is attached to the swivel shaft 26.
  • Corresponding lower sprockets 35 are rotatably supported in fixed bearings 33 by means of bearing bolts 34.
  • Two pivot levers 38 are attached to the pivot shaft 26, the free ends of which are connected in the transverse direction by means of a cutting wire 39.
  • a tensioning device 40 enables the cutting wire 39 to be tensioned.
  • a pre-cutting roller 42 is provided for chamfering the rounded head part of the brick.
  • the front end of the beaver tile is a round end 59, the shape of which is determined by the movement of the cutting wire 39 and can be changed.
  • the rear end is designed as a flat end 58.
  • FIG. 6 shows a separating element in the form of a cutting pin 65, with a head 66 and a shaft 67.
  • a clamping socket 68 is provided for holding and reinforcing.
  • the double beaver tile blank reaches e.g. cut to length over the feed platform 20, between the two guide rollers 9.
  • the cutting pins 10 and 17 are in their open position. Their lateral spacing is set such that they cut through the end connecting webs 52 in the manner shown in FIG. 4 over a large part of the thickness of the connecting webs as they move.
  • the head 66 of the cutting pins 65 or 10 and 17 ensure a good separating groove, which ensures that the connecting webs 52 break relatively smoothly when the tiles are later separated.
  • the center connecting web 61 is also provided with TARGET breaking notches 53, which, however, are already generated when the molded article is formed.
  • the circular arc cutter 4 also comes into operation by the cutting wire 39 rounding the blank in the sense of FIG. 4.
  • the two pre-cutting rollers 42 chamfer the outer edges of the bricks, which ensures that there are no irregular edges during the cutting process.
  • the great advantage of the separating pins with a head is that the material is not glued and the target break joints transition into the material in such a way that the bricks can be separated safely and without damage.
  • a measuring roller is arranged before it enters the cutting device.
  • the circular arc cutting device described works template-free with the wire cutter, which enables a significant simplification of the system and a safer working.
  • a separating device is shown, which is based on the principle of punching instead of cutting.
  • Connection frames 80 ensure a stable construction.
  • Upper punching knives 83 are installed in a holder 81 by means of fastening screws 84.
  • the punching knives, both the upper 83 and the lower 87, are guided via four synchronizing columns 85, on which the punching knives 83 and 87, safely guided, move up and down via linear ball bearings 100.
  • These knives move over Swivel arms 90 and bearing housing rotating rods 91, which punch knives are synchronized with each other via these rods.
  • the punching knives are adjusted using adjusting screws 94. Synchronizing linkages 95 prevent asymmetrical loading of the punching knives.
  • the movement is carried out pneumatically by a piston / cylinder unit 97, with corresponding ball head bearings 98 ensuring practically smooth transmission.
  • the piston / cylinder units 97, four in number, are attached to a cylinder holder 101.
  • the punching knives 83 and 87 are designed in accordance with the desired punching shape in the double beaver blank, the punching knives being close to one another for the separation of the noses and having a corresponding distance for punching the desired breaking notches.
  • the double beaver preforms are assembled by means of the punching knife with a counter-movement of the punching knife. It is therefore very simple and enables the plants to work quickly and continuously.
  • the way in which such a confectioning takes place depends on the sound quality, with the punching ensuring uniform chamfering.
  • the punching device is normally followed by a cutting device for arc cutting, as was explained with reference to FIGS. 1 to 5.
