Definitions

  • the invention relates to a device for adjusting the knife gap on drum shears, the knife drums of which are seated firmly on a pair of support shafts with helical toothed drive gears and have longitudinal recesses for receiving knife blocks in which these can be clamped with the aid of fastening elements which can be pressurized and act on clamping wedges.
  • the setting of the knife gap has so far been carried out in such a way that one of the helical drive gearwheels on its seat on the journal of the supporting shaft is axially displaced with the aid of an actuating device and, due to the radial component of the supporting force on the counter teeth of the other helical drive gear causes a relative rotational displacement of the knife drum relative to the other knife drum, with which the width of the knife gap of the knife blocks of both drums can be adjusted.
  • the device has the main disadvantage that the drive gear on the shaft journal of the wheel shaft of the knife drum are arranged in a rotationally fixed but axially displaceable manner, and that this displaceability has to be canceled again during the cutting operation of the scissors, that is to say blocked. This necessity required considerable technical effort, namely Eg axially parallel in the grooves between the support shaft journal and drive gear adjustable wedges with axial locking elements and a sliding device placed on the end face of the pin for the wedges.
  • Such a device for axially displacing a support shaft is not suitable for adjusting the knife gap in the generic drum shears because the cutting edges of the knife blocks are all convex to the outside in an arcuate manner and therefore when one of the knife drums is axially displaced together with the knife block sitting on the drum Cutting symmetry between the knife block of one and the other knife drum is disturbed, making cutting impossible (DE-AS 2037270).
  • the device Starting from a known device for fastening the knife blocks in longitudinal recesses of the circumference of the knife drums with the aid of pressurizable fasteners which act on clamping wedges and which, for example, allow the pressurization of the fasteners to be released by hydraulic counterpressure and thus make the knife blocks displaceable in the longitudinal recesses the task, the device to improve the knife gap on the generic drum shears so that the disadvantages of the complex devices for moving a drive gear on the support shaft and its blocking are avoided and the axial position of both knife blocks zue nander remains unchanged during the setting process of the knife gap.
  • This object is achieved by holding stops arranged in the supporting frame of the drum shears and fixing the cutter bars during an axial displacement on one of the supporting shafts with cutter drum and drive gear wheel relative to the other in their position in the longitudinal recesses of the cutter drum.
  • these holding stops can have stop pieces which can be moved in and out in the area of the end faces of the knife blocks.
  • the holding stops hold the knife bar in the longitudinal recess of the knife drum to be adjusted by axial displacement during the displacement process in its original position relative to the knife bar of the other, not displaced knife drum, so that the position of the cutting edges of both knives remains unchanged transversely to the radial one.
  • the fastening elements of the clamping wedges are again subjected to pressure and the holding stops are moved out of the area of the cutter bars.
  • the two knife drums 1 and 2 are arranged on support shafts 3 and 4, on the drive pins 3a, 4a of which the helical gear meshing drive gears 5 and 6 are seated.
  • the lower support shaft 4 with the knife drum 2 is mounted in fixed roller bearings 7 and 8 in the support frame 9 of the drum shears.
  • the upper support shaft 3 is supported in roller bearings 10 and 11, which permit an axial displacement of its inner ring 10a, 11a with the rollers relative to the outer ring 10b, 11b arranged fixedly in the support frame 9.
  • a pin shoulder 12 is placed, which is surrounded by an inner ring collar 14a of a cylinder sleeve 14 which is piston-like in a guide 15 arranged in the support frame 9 in the direction of the axis of rotation of the support shaft 3.
  • the ring end faces of the collar 14a are bordered by two axial bearings 16 and 17 seated on the pin boss 12 and axially fixed by a nut 18 screwable onto a threaded end 12a of the pin boss 12.
  • the cylinder sleeve 14 has on its ring face facing away from the inner ring 14a a flange cover 19 with a central threaded bore 19a into which a threaded spindle 20 engages, which can be set in rotation by a motor 40 via a worm gear 22.
  • This perforated disc 24 is provided in a manner not shown with a display scale which is assigned to the actuating arm 21.
  • stop pieces 27 are provided in vertical guides, which can be moved up and down by piston-cylinder units 28 in the direction of the arrows shown.
  • the mutually facing, slightly inclined holding surfaces 27a of these stop pieces act on the end faces 29a of the knife bar 29 in the longitudinal recesses 1a of the knife drum 1.
  • These knife bars 29 are, as can be seen in FIG. 2, by means of a clamping wedge 30 which has a pull rod 32 below it The action of a spring assembly 33 is clampable in the longitudinal recess 1a.
  • the pull rod 32 carries at its end facing away from the clamping wedge 30 a piston 34 which is guided in a cylinder piece 35 and can be acted upon by a pressure medium via a feed line 36 in a manner not shown.
  • the tensioning wedge 30 is brought out of tension against the action of the spring assembly 33 and the knife bar 29 can slide in the longitudinal recess 1a. If the holding surfaces 27a of the stop pieces 27 act on the two end faces 29a of the cutter bar 29 in the manner shown in FIG.
  • the cutter bar 29 remains in the position shown while the cutterhead 1 when the motor 40 is actuated by the spindle 20 via the cylinder sleeve 14 and the latter Inner ring collar 14a is displaced axially in the direction of the arrows V in one direction or the other. Shows the displacement of the actuator arm 21 on the (not shown) to scale, and the device can then, after the knife bar 29 by means of the clamping wedge 30 and the spring assembly 33 in the L Vilsaus supraung 1a was clamped again by retracting the locking cam 23 into a perforation of the perforated disk 24. The stop pieces 27 are moved back into their starting position with the aid of the piston-cylinder units 28 and the drum shears are ready for cutting.
