Definitions

  • the invention relates to roller shears according to the preamble of claim 1.
  • each knife shaft is surrounded by a sleeve on which the roller knives can be positioned axially.
  • the sleeve can be stretched by a hydraulic medium introduced between the knife shaft and the sleeve, as a result of which the roller knives can be clamped on the knife shaft.
  • the manipulator of the known roller shears is designed in such a way that the roller knives of the lower knife shaft can only be adjusted while taking the roller knives on the upper knife shaft and the manipulator must perform a lifting movement when the roller knives are individually adjusted on the upper knife shaft. to get rid of the roller knives of the lower knife shaft.
  • Figure 1 shows schematically a roller shear in front view
  • Figure 2 is a sectional view taken along line 2-2 in Figure 1;
  • Figure 3 is a sectional view taken along line 3-3 in Figure 1;
  • FIG. 4 schematically shows a top view of a manipulator with an associated roller knife along the line 4-4 in FIG. 1;
  • FIG. 5 shows an axial sectional view of a mechanical roller knife tensioning device
  • FIG. 6 shows an axial sectional view of a hydraulic roller knife tensioning device
  • FIG. 7 shows an end view of the tensioning device from FIG. 6
  • Figure 8 shows a preferred roller knife assembly
  • FIG. 9 shows another preferred roller knife arrangement.
  • the roller shear 1 shown schematically in Figure 1 comprises a machine frame 2 with two knife shafts 5, 6 rotatably mounted in stands 3, 4 of this frame.
  • the knife shafts are adjustable relative to each other in a manner yet to be described, so that their mutual distance can be set.
  • the lower knife shaft 6 (in FIG. 1) can be driven directly via a pulley 7 in a known manner by a motor (not shown) accommodated in the machine frame 2.
  • FIG. 2 shows, in the area of the stator 3 sit on the knife shafts 5 and 6, gear wheels 8 and 9, which are connected by further gear wheels 11, 12 mounted on the stator 3 in such a way that when the lower knives are driven serwelle 6 the upper knife shaft 5 is taken in opposite directions via the pulley 7.
  • the upper knife shaft 5 can be displaced vertically by means of a slide 13 in the stand 3, so that the relative distance to the lower knife shaft 6 can be set.
  • the stand 4 in which the upper knife shaft 5 is also adjustably mounted by means of a slide.
  • the adjustment of the upper knife shaft 5 by the mentioned slides 13 is so small that the gears 8, 11 do not disengage and thus both knife shafts 5 and 6 can always be driven.
  • Roller knives 14 are arranged on the knife shafts 5 and 6 and rotate together with the knife shafts.
  • the roller knives can be positioned and clamped in the desired manner on the knife shafts 5, 6 in a manner to be described. Since the roller knives of one knife shaft are very closely adjacent to those of the other knife shaft in the final state, the two knife shafts 5 and 6 are removed from one another in the manner described during the positioning of the roller knives on their knife shafts. After positioning has been carried out, the two cutter shafts 5, 6 are brought closer to one another again.
  • roller knives 14 on the left are arranged on their knife shafts 5, 6 in pairs opposite one another, so that a correspondingly wide sheet metal strip or a correspondingly wide sheet metal plate can be divided into three strips of different widths, the strip width in each case being the distance between the Roller knife 14 on their knife shafts 5, 6 corresponds.
  • the two roller knives 14 arranged on the far right in FIG. 1 on the knife shafts 5, 6 are out of operation. They can be put into operation if, for example, a sheet metal strip is to be divided into more than three strips.
  • the roller shear 1 also includes, as well FIG. 1 shows a manipulator 15, with the aid of which the roller knives 14 can be positioned and clamped individually and independently of one another on their knife shafts 5, 6.
  • the manipulator can be moved back and forth parallel to and across the entire axial length of the cutter shafts 5 and 6 by means of a sliding guide 20 running horizontally along the machine frame 2.
  • the manipulator 15 is driven via a screw spindle 16 which engages in a corresponding nut 17 of the manipulator 15.
  • the screw spindle 16 can be driven in either direction of rotation by a motor 18 arranged in the machine frame 2.
  • the mentioned slide guide 20, on which the manipulator 15 is displaceable is indicated schematically.
  • the manipulator has a frame 19 which surrounds both knife shafts 5, 6 and the roller knives 14 seated on them in a ring.
  • a total of four slides 21 are provided in pairs in the frame 19 of the manipulator 15, which have concavely curved cutting edges 22 with which they can engage positively and without play in corresponding grooves 23 of the roller knives 14.
  • Each two opposing slides 21 are assigned to a knife shaft 5 or 6 and the roller knives 14 arranged thereon.
  • the slides 21 are horizontally displaceably mounted in the frame 19 and can be moved by remote-controlled hydraulic or pneumatic cylinders 24 so that their cutting edges 22 either engage in the grooves 23 of the roller knives 14 or are pulled out of them.
  • fingers 25 are also displaceably mounted on both sides of the slide, which can be advanced or retracted remotely with the aid of working cylinders 26 with reference to the roller knife 14. These fingers 25 serve, in a manner yet to be described, to actuate the clamping means, with the aid of which the roller knives 14 can be clamped on their knife shafts 5, 6 or released from them.
  • FIG. 5 shows the structure of a roller knife 14 in a first embodiment with mechanically acting clamping means.
  • On the outside of the knife shaft 5 (the same applies to the knife shaft 6), an outwardly open axial groove 31 is formed, in which a fitting spring 32 is displaceable.
  • the feather key 32 is firmly connected by screws 33 to a hub part 34 surrounding the knife shaft 5. In this way, the hub part 34 is held on the knife shaft 5 in a rotationally fixed but axially displaceable manner.
  • Knife part 36 and lifting part 37 with the lifting ring 38 are thus arranged together with the hub part 34 in a rotationally fixed manner on the knife shaft 5, but are axially displaceable on this shaft.
  • the knife shaft 5 is enclosed by an annular part 41 which partially extends over the hub part 34.
  • the ring part 41 is freely rotatable on the measuring shaft 5.
  • a threaded pin 42 which engages in a corresponding annular groove 43 of the hub part 34, prevents axial movement of the ring part 41 relative to the hub part 34 and thus ensures the cohesion of these two parts.
  • the outer circumferential surface 44 of the hub part 34 and the inner circumferential surface 45 of the ring part 41 overlapping this surface 44 are eccentric to the central axis of the knife shaft 5.
  • the inner peripheral surface 46, with which the ring part 41 is seated on the knife shaft 5, is circular cylindrical and concentric with the central axis of this shaft.
  • the stop blocks 48 are also drawn with their radially directed stop surfaces. It can be seen in FIG. 4 how the finger 25 located there on the right abuts the stop surface of the stop block 48 and thereby prevents the relevant ring part 41 from rotating in a certain direction of rotation. The finger 25 on the left in FIG. 4, on the other hand, is withdrawn and is therefore not able to strike a stop block 48. As can also be seen from FIG. 4, the two fingers 25 are each so far away from the slide 21 that whenever the concave cutting edge 22 of the slide engages in the groove 23 of a roller knife 14, a finger 25 on the stop block 48 of this knife associated ring part 41 can attack. If, in FIG. 4, the slider 21 with its cutting edge 22 engages in the groove 23 of the roller knife 14 on the left, the finger 25 on the left in this figure could come into engagement with the stop block 48 of the left roller knife 14.
  • All of the roller knives 14 can thus be positioned individually and independently of one another on their knife shafts 5, 6 by the manipulator 15 in the following manner: With knife shafts 5, 6 (slide 13 in FIG. 2) that are spaced apart from one another, the manipulator 15 is positioned in front of a specific sitting on the upper or lower knife shaft 5 or 6 Roller knife 14 brought up, initially assuming that this roller knife is not clamped on its knife shaft. Then the two slides 21 assigned to the relevant knife shaft are advanced so that they engage in the groove 23 of the roller knife 14. Then, by means of a corresponding remote-controlled displacement of the manipulator on its sliding guide with the aid of the screw spindle 16, the roller knife 14 now taken along by the manipulator is positioned at the desired point on the knife shaft.
  • clamping means described in connection with FIG. 5 act due to the eccentricity described Circumferential surfaces 44, 45 purely mechanically.
  • clamping devices which act hydraulically are described in connection with FIGS. 6 and 7.
  • a roller knife 14 comprises a clamping sleeve 51 which surrounds the associated knife shaft (not shown in FIGS. 6 and 7).
  • the clamping sleeve 51 has on one side a radially projecting end wall 52 from the knife shaft.
  • a hub part 53 is pushed onto the clamping sleeve 51 and has on its inner peripheral surface facing the sleeve 51 a recessed annular space 54 filled with hydraulic medium. Sealing rings 55 are arranged on both sides of the annular space 54 between the sleeve 51 and the hub part 53.
  • a feather key 56 which is fastened with a screw 57 to the end wall 52 of the sleeve 51 and to the hub part 53, projects into a corresponding groove axially extending on the outside of the associated knife shaft, which corresponds to the groove 31 in FIG.
  • the feather key 56 thus holds the clamping sleeve 51 and the hub part 53 in a rotationally fixed but axially displaceable manner on the knife shaft.
  • a ring part 58 is rotatably seated on the outer circumferential surface of the hub part 53 and is prevented from axially displacing relative to the hub part 53 by a radially projecting ring 59 connected to the latter and by a step 61 on the hub part 53.
  • the hub part 53 has radially running bores 62, which are connected to the annular space 54 and in which the pistons 63 can be moved in a sealed manner.
  • the heads of the pistons 63 protrude beyond the circular cylindrical, outer circumferential surface of the hub part 53.
  • the bores 62 like the annular space 54, are filled with hydraulic medium. Accordingly, if one or if several of the pistons 63 are displaced radially inwards in the bores 62, the hydraulic pressure in the annular space 54 increases.
  • the clamping sleeve 51 is accordingly pressed together and clamped on the knife shaft enclosed by it. Since the clamping sleeve 51 'is fixedly connected to the hub part 53, the entire roller knife can be clamped in a desired position on the knife shaft in this way.
  • the hub part 53 has a step-shaped recess which is open towards the right and in which, in the manner shown in FIG. 5, a knife part 36 and a lifting part 37 with a lifting ring 38 can be firmly arranged, which is not the case in FIG. 6 is shown specifically.
  • the ring part 58 In order to move the pistons 63 in the hub part 53 radially inwards in order to increase the hydraulic pressure in the annular recess 54, the ring part 58, as can best be seen from FIG. 7, has inner regions which are eccentric to the central axis of the knife shaft Surfaces 60 in such a way that with a corresponding rotation of the ring part 58 relative to the hub part 53 which is circular cylindrical on its outside (to the right in FIG. 7), the inner distance between the inner surface 60 and the hub part 53 becomes smaller, as a result of which the piston 63 passes through the inner surface 60 acting on the piston head is inevitably pressed inward in its bore 62.
  • the piston 63 is displaced radially outwards by the prevailing hydraulic pressure during a relative rotation between the hub part 53 and the ring part 58, so that the tension is released and the roller knife 14 can now be axially displaced on its knife shaft.
  • the hub parts 34, 53 and ring parts 41, 58 project axially on one side over the knife part 36 and lifting ring 38.
  • the arrangement of knife part 36 and lifting ring 38 can be made such that either knife part 36 or lifting ring 38 is adjacent to the hub or ring part.
  • a total of six roller knives 14 on the upper knife shaft 5 and the lower knife shaft 6 are arranged as closely as possible next to one another, the respective roller knives 14 abutting each other.
  • each knife shaft is such that the ring part 41 alternately adjoins a knife part 36 and a lifting ring 38, respectively on the upper shaft 5 each knife part 36 and Aushebe ⁇ ring 38 are reversed, as on the lower knife shaft 6. All ring parts 41 are directed in the same direction (to the right).
  • a sheet metal strip is divided using the roller knives at the adjacent edges of a lower and upper knife part 36. In the arrangement shown in FIG. 8, the same minimum strip width can be achieved, which is indicated by dimension A.
  • the roller knife arrangement according to FIG. 9 differs from that according to FIG. 8 in that the ring parts 41 are directed alternately towards different sides, but in each case on the knife shaft 5 there are always lifting rings 38 on the ring parts 41 and on the knife shaft 6 always knife parts 36 connect to the ring parts. With this arrangement of the roller knives there are alternating different strip widths, the dimensions of which are indicated by B and C in FIG. 9. B is smaller, C is larger than A. A can be, for example, 73, B 40.5 and C 106 mm.
  • both cutter shafts 5, 6 are driven because of the gear wheels 11, 12 acting between them. In principle, it is sufficient to drive only one of the knife shafts 5 or 6. When a sheet is inserted between the roller knives, the other knife shaft and the roller knives sitting on it are inevitably taken along.
  • roller shear described is assigned a programmable computer in a manner known per se and therefore not specifically illustrated and described, which computer records all the rotary and displacement movements of the parts described, in particular the knife shafts 5, 6, the manipulator 15, the slide 21 and the fingers 25 controls and in which the respective positions of the roller knives are stored, so that any preselectable positions of the roller knives can be set.
