Definitions

  • the present invention relates to a vertical frame sawing machine, intended for cutting a hard material, comprising a frame carrying said frame provided with a series of armor blades stretched over the frame, driven by a movement back and forth from top to bottom and articulated in the vicinity of each corner by pivots to pads engaged in slides.
  • the machine also includes a support table carrying the material to be sawn.
  • the invention relates in particular to a machine with vertical reciprocating movement of the blades, in which sawing takes place in both directions.
  • Document DE-C-446.196 discloses a vertical frame sawing machine intended to cut a block of hard material simultaneously into a series of parallel plates.
  • the machine includes a series of armor blades mounted on the vertical frame animated by an alternating rectilinear movement back and forth.
  • the machine also includes a saw table capable of carrying the material to be sawed and of holding the blanks of the plates in place during sawing.
  • the frame is articulated in the vicinity of each corner, by means of a pivot, to a runner run along a slide fastened to the body of the sawing machine.
  • each of the pads to the frame is intended to adapt the parallelism of the slide after mounting and before putting the sawing machine into operation.
  • This articulated connection also reduces wear on the pads and slides.
  • Document FR-A-2498977 also describes a saw with multiple armor blades, intended to cut into slabs of large blocks of marble or stone.
  • a vertical frame with relatively short saw blades is moved up and down. It allows the sawing, during the two phases of movement of the saw frame, of blocks of practically unlimited length.
  • the frame is guided at the midpoint and at the upper end of each of its sides, by two Watt guide systems, each provided with a lever articulated at each of its ends to a pendulum swinging around a fixed pivot. This arrangement allows a substantially straight guide of the frame.
  • one of the pendulums can be actuated by an eccentric, in order to ensure an almost circular sawing curve of the blade on the block of marble or stone in order to reduce the number of teeth engaged with the block.
  • the eccentric is driven at the same speed of rotation as the flywheel causing the vertical frame to move back and forth.
  • Watt's guide bars therefore oscillate in phase with the vertical frame.
  • a sophisticated balancing system compensates for the inertial forces of parts subjected to reciprocating motion. It allows to reach a speed of 260 strokes / min.
  • the main drawback of this improved Watt device is the invalidity of the sawing curve, in the sense that the envelope of the successive positions of the blades is an irregular curve which causes strong pressure spikes on each of the blades at certain times. of the frame tilting stroke.
  • a sawing machine which consists of one or more blades of armor fixed to a vertical frame to which one communicates by means of a connecting rod driven by a steering wheel, a movement back and forth from top to bottom on a fixed vertical plane.
  • a transport table brings the block of marble or stone to be engaged in a sawing direction substantially perpendicular to the blades and allows the sawing plane to cross the bearing plane of the block to be sawed.
  • the vertical arrangement of the frame allows the machine to saw blocks of indefinite length, and this with relatively short blades so as to avoid any untimely deflection of the blade.
  • the machine according to the Belgian patent uses armor blades provided with hard metal teeth, capable of making the cut during movement in one direction only.
  • the combination of the upward and downward vertical movement of the frame and the horizontal pendulum movement provides a more or less flattened ovoid sawing trajectory allowing to obtain in one direction, a gradual penetration of the teeth along a soft curve and in the other sense, the release of teeth, away from marble or stone.
  • These cyclic deformations of the armor blade cause deviations of the latter and very unfavorably influence the sharpness of the cut of the marble. or stone.
  • the present invention aims to remedy these drawbacks. It offers a vertical frame sawing machine, intended for cutting hard material, comprising a series of armor blades stretched over the above-mentioned frame, animated back and forth from top to bottom and articulated in the vicinity of each corner by pivots to pads engaged in slides and a support table carrying the material to be sawn, essentially characterized in that the slides are mounted sliding along crossed guides fixed to the frame of the machine.
  • This vertical frame sawing machine implements armor blades provided with teeth with diamond concretion, which can possibly work in only one sawing direction.
  • each abrasive grain has behind it a volume of binder called a comet tail which allows it to be supported during its cutting effort.
  • the lower slides are each connected to a link controlled by an eccentric mu in a vertical plane and the upper slides are each connected to a link controlled by an oscillating pinion with double cam driven in complete rotation and traversed by a pair of rollers which communicate a pendulum movement to a control arm.
  • the pads are articulated to the above frame.
  • the machi ne comprises a drive motor and a pair of flywheels intended for up-and-down actuation from top to bottom of the frame, and arranged in a pit.
  • the invention also relates to a method of implementing a sawing machine with a vertical frame, characterized in that a rectilinear movement synchronized is imparted to the upper slides of the frame by means of an oscillating pinion with double cam driven in rotation. complete and traversed by a pair of rollers articulated around a drive shaft.
  • each of the four corners of the frame is printed with a synchronized pendulum movement resulting for each lower corner of the frame from two crossed translational movements, the first of which is determined by the race of a shoe along d 'a slide and the second by the sliding of the slide along guides under the action of a rod driven by an eccentric driven in rotation in a vertical plane and for each upper corner of the frame, two crossed translational movements including the first is determined by the race of a shoe along a slide and the second by the sliding of the slide along guides under the action of a rod moved by an oscillating pinion with double cam with pendular movement traversed by two rollers arranged symmetrically with respect to a control shaft, so as to obtain at all times that the blade, whatever its position, is tangent to an ovoid sawing curve.
  • the sawing machine according to the invention is a multiple blade machine carried by a vertical frame. It is intended for cutting blocks of granite or very hard material in the form of more or less thin plates.
  • the machine designated as a whole by the reference sign 1 is partially mounted below, in order to better take up the vibrations.
  • a frame 2 comprising four pillars 3 which rest on the bases 4 of a workshop pit above which is mounted a support table 5 carrying a block 9 of material to be sawed.
  • a support table 5 carrying a block 9 of material to be sawed.
  • On the frame 2 are mounted mechanisms 6 for supporting the slides of a saw frame formed by a vertical rectangular frame 7 on which are stretched by means of tie rods, one or more armor blades 8 provided with suitable teeth saw in both directions of blade movement 8.
  • the saw frame 7 is formed of metal beams assembled at their ends by wider cross members 10 so as to form an extremely rigid rectangular frame.
  • the frame 7 is subjected to a reciprocating movement from top to bottom printed by a motor 11.
  • This motor 11 rotates, by means of belts 12, a single-elbow crankshaft 13 carrying two flywheels 14 on the one hand and on the other side of the elbow 13 (FIG. 2).
  • a balancing system 35 makes it possible to attenuate the vibrations of the bases 4. It is formed by two flywheels 36 arranged on either side of the first flywheels 14. These two flywheels 36 are rotated at the same speed as the first flywheels 14, but in reverse by a drive device not shown.
  • a connecting rod 15 operates from top to bottom the saw frame 7, which in the vicinity of its four corners, carries pads 16 engaged in slides 17,18, 19,20 which impose on the frame a stroke contained in a vertical plane.
  • the slides 17, 18, 19 and 20 are slidably mounted relative to the frame 2 of the machine 1, along guides 31, 32 defining a trajectory perpendicular to the direction of guide of the slides 17, 18, 19 and 20.
  • the upper slides 17, 18 move together, parallel to themselves along the guides 31, 32 in the direction of the arrows X, Y.
  • the lower slides 19, 20 move together, parallel to themselves along guides 31, 32 in the opposite direction to that of the arrows X, Y by rotating the frame around a horizontal middle axis not shown.
  • the pads 16 are articulated to the frame by pivots 27 shown in Figures 3 and 4.
  • the right slides 17,19 and the left slides 18,20 each have planar guide surfaces 34 and guide surfaces 29,30 in V, that is to say forming a certain angle between them ( Figures 5 and 7).
  • the slides 17, 18, 19 and 20 have a variable position determined by four links 21, 23 which give them an alternating rectilinear movement in the direction of the arrows X, Y along two guides 31, 32 fixed to the frame 2 of the machine sawing 1.
  • the corners of the frame 7 are subjected to two simultaneous movements, one of which is an alternating rectilinear movement from top to bottom and the other an alternating rectilinear movement in a horizontal plane.
  • the saw blades 8 determine an ovoid sawing trajectory with a progressive radius of curvature (FIG. 9) which makes it possible to reduce the sawing force by reducing the number of teeth, in contact with the material to be sawed and improve the efficiency of watering.
  • a gradual cutting of the stone block is carried out, by printing at the four corners of the frame, a synchronized pendulum movement using the four articulated links 21, 23 controlled respectively by the eccentric 22 and the oscillating pinion 24.
  • This pendulum movement has the effect of urging, in the ascending direction, the teeth which line the upper part of the armor blade and urging in the descending direction the teeth of the lower part of the armor blade.
