Definitions

  • the invention relates to a gang saw with a guide rails guided along lateral guide rails, which has a gate frame with two extension bars for clamping parallel, only in a stroke cutting blades, and with a sliding crank drive, the lateral push rods in the vicinity of the draw bar is connected to the saw gate.
  • a gang saw is the DE 27 21 842 refer to.
  • the saw gate In gate saws with saw blades clamped in a gate frame, the saw gate usually driven by a slider drive is mounted by means of sliders in lateral guide rails of a frame, with the possibility of the push rods of the slider crank drive either in the vicinity of the sliding frame closer or farther of the two extension bars on the gate frame to steer, between which the saw blades are clamped.
  • the compound of the push rods with the closer of these stretch bars brings not only better accessibility to the saw gate, but also favorable loading conditions for the gate frame with him, when the cutting stroke in the direction of the closer draw bar, because in this case the longitudinal beams connecting the stretch bars of the gate frame during of the cutting stroke are loaded on train.
  • the achievable stroke frequency remains limited. With the increase in the stroke frequency, namely the mass forces and thus the leadership loads increase disproportionately.
  • the invention is therefore based on the object, a gate saw of the type described in such a way that a significant increase in the stroke frequency of the saw gate can be achieved without having to fear overloading the guides of the saw gate.
  • a change of the gate frame with a small conversion effort should be made.
  • the invention solves the problem set by the fact that the two push rods of the slider crank drive on a common cross member for receiving the gate frame in the vicinity of the crank drive closer of the two stretch bars attack that the cross member supports by means of guides on the side guide rails and that the cross member opposite his guides is held pivotable about an axis perpendicular to the guide rails and the cross member.
  • the guides for the cross member and the base frame in the area of the drawframe remote from the drawbar be designed as recirculating ball guides that allow a largely play-free sliding guide the saw gate, which also leads to an extension of the service life of the saw blades leads.
  • the mounted on the side guide rails, connected to the sliding crank cross member not only allows a favorable force in the gate frame, but also brings easy replacement conditions for the saw with him, because not removed for removing the gate frame, the drive connection between the cross member and the sliding crank must become.
  • the gate saw shown has a frame 1, in which a sliding crank drive 2 is mounted for driving a sawing gate 3.
  • the sliding along side guide rails 4 polegegatter 3 comprises a gate frame 5 with two interconnected by longitudinal beams stretching beams 6, 7, between which the saw blades 8 are clamped.
  • the gate frame 5 is detachably connected directly to guides 9 for the lateral guide rails 4 in the region of the draw-bar drive 2
  • the gate frame 5 rests in the region of the opposite draw bar 6 closer to the draw bar 6 on a cross member 10
  • the axially projecting pivot pin 11 for lateral push rods 12 of the sliding crank drive 2 carries.
  • the cross member 10 is held in a receiving groove 13 of the draw bar 6. Since the groove walls of the receiving groove 13 converge towards the bottom of the groove and the cross member 10 correspondingly inclined mating surfaces 14, the cross member 10 engages without play in the receiving groove 13 when the cross member 10 is pulled by means of fastening screws against the groove bottom.
  • the cross member 10 is guided over guides 15 along the lateral guide rails 4, so that there is a corresponding displaceability of the gate frame 5 along the lateral guide rails 4 in the region of the drawbar crank 2 closer draw bar 6.
  • the connection between the cross member 10 and the guides 15 is not rigid in order to withhold torque loads of the guides 15 at a bend of the cross member 14 can. For this reason, the attachment of the cross member 10 on the guides 15 via axes 16, which are perpendicular to the respective guide rail 4 and the cross member 10.
  • the sliding guide for the gate frame 5 remains largely free of constraining forces that could adversely affect the guidance accuracy, so that advantageous conditions for increasing the Stroke frequency of the saw gate 3 are met, especially since a weight-saving design results without affecting the interchangeability of the saw gate 3.
  • To release the gate frame 5 so only the connections of the gate frame 5 are on the one hand with the guides 9 and on the other hand to solve with the cross member 10, which can be done with little time and effort.
  • the guides 9, 15 for the gate frame 5 in the region of the drawbar remote drive beam 7 on the one hand and the cross member 10 on the other hand can be designed as sliding guides arise with regard to the accuracy of the gate frame 5 more favorable conditions through the use of recirculating ball bearings, which is advantageous on the cutting accuracy, the achievable cutting speed and beyond on the service life of the saw blades.
