Definitions

  • the flaps each in the form of a plain plate are connected to each other for angular movement in the same plane to form the endless chain body, it is possible to obtain a sufficient tension-resisting force by the relatively thin flaps.
  • the thickness of each of the cutting device can be reduced.
  • the cutting allowance of the workpiece can be reduced to improve the yield.
  • the chain cutter is a high performance cutting device.
  • Connecting of the flap 1 is done as follows. First, as shown in Fig. 8, the flap 1 rests on a base B of the press machine with the staking groove 12 directed upwardly. The connecting projection 8 of another flap 1 is fitted in the connecting cut-out 10 from the side of the vertical peripheral wall 10B, and the lower end of the punch P is abutted against the staking groove 12. Then, a pressure is applied to the punch P by the press machine. By doing so, as shown in Fig. 10, the punch P pushes and enlarges the staking groove 12. Thus, a projecting portion 14 is bent inwardly, so that the vertical peripheral surface 10B is abutted against the tapered surface 8A without any gap.
  • a life judging mechanism for the flap 1 will next be described.
  • a shallow C-shaped life judging groove 16 is formed at a center of the inner peripheral edge of the connecting cut-out 10. A distance from the center 02 of the connecting cut-out 10 to the bottom surface of the life judging groove 16 is set to one slightly larger than the maximum radius of the connecting projection 8.
  • Fig. 14 shows a condition that the workpiece W such as a structure or the like is cut horizontally.
  • the inner-peripheral-blade type chain cutter C is arranged horizontally around the structural object W, and extends among and is wound horizontally about an inner-­side support pulley 50, a pair of outer-side support pulleys 52 and a moving pulley 54, all located at the same height with each other.
  • the suitable arrangement of the pulleys 50, 52 and 54 is determined depending upon conditions at work site. Thus, the arrangement of the pulleys 50, 52 and 54 should not be limited to the illustrated arrangement.
  • the chain cutter C is installed in the grooves 72 in the aforesaid respective guide jigs 68.
  • the guide jigs 68 are arranged horizontally at the corner of the workpiece W to be cut.
  • the flange 70 is fixedly mounted to the wall surface of the workpiece W, by means of, if the workpiece W is concrete or the like, a dryvit, a boring anchor, a chemical bonding or the like is suitable. Otherwise, bolt fixing or the like is also possible.
  • the moving pulley 54 is moved horizontally toward the direction of the arrow in Fig. 4.
  • the drive motor 64 operates on the drive sprocket 62, while a tension force is applied to the chain cutter C, to cause the chain cutter C to travel in the direction shown by the arrows.
  • the connecting sections between adjacent flaps 1 wear with use, causing the endless chain cutter C to gradually lengthen so that the cutter C becomes unusable. Accordingly, the chain cutter C is not susceptible to sudden breakage during cutting, and its safety is high.
  • the chain cutter C is in the form of a chain and is relatively light in weight, handling such as transportation or the like is easy. Further, since vibration occurring due to cutting is attenuated at the connecting sections between each pair of adjacent flaps, noises can also be reduced as compared with other cutting tools.
  • the engaging projection 40 and the engaging groove 38 of the flap 1 are in mesh with each other at the inwardly curved section, and the flaps 1 are firmly connected to each other. Accordingly, there do not occur problems such as the variation in the cutting widths and wondering of abrasive bits 30 due to vibrations of the individual flaps 1. Thus, it is possible to considerably raise the degree of flatness and the surface roughness of the cut surface as compared with a wire saw or the like. Furthermore, since the inner side surface of the flap 1 is abutted against the workpiece W at the inwardly bent section, the slit 22 will not open accidentally, so that there is no danger of the cutting device 4 to fall down from the recess 18.
  • the chain cutter C is wound about a pair of fixed rotatable sprockets 100, a pair of rotatable and movable sprockets 104 and a workpiece W.
  • This plane can be either vertical or horizontal.
  • Each of the pairs of sprockets is provided with corresponding pair of support shafts 102 for sprocket 100 and support shafts 106 for sprockets 104.
