ることにある。A characteristic structure of a cutting machine for a ring body according to the present invention is such that it can be driven and retracted individually from a frame toward a fixed ring body, and the cutting blade A pair of support rods, which are swingably supported in the retreating direction, are provided for each cutting blade to form the drive shaft portion, and the tips of both support rods are attached to the ring body in the fixed state at substantially the same speed. Switching means is provided for switching the operating state of both support rods between a first state in which the support rods are stationary and a second state in which one support rod is stationary and only the tip of the other support rod is directed toward the ring body, and the cutting is performed. Provided with a pressure sensor for detecting the cutting pressure acting on the blade, based on the detection result of this pressure sensor, if the cutting pressure is less than the set value,
There is provided a control device for switching the switching means so as to be in the first state, and for switching the switching means to be in the second state when the cutting pressure becomes equal to or higher than the set value.

てリング体を切断する。In other words, because of the above-mentioned structure, the ring body can be divided at a plurality of locations in the circumferential direction as follows. First, the ring body is fixed by the fixing portion. Since the cutting pressure does not act on the cutting blade at the beginning of driving the cutting machine, the control device switches the switching means to the first state based on the detection result of the pressure sensor that the cutting pressure is smaller than the set value. The tips of both support rods are directed toward the fixed ring body at almost the same speed. When the cutting blade bites into the ring body and the cutting pressure becomes equal to or higher than the set value, the control device switches the switching means to the second state based on the detection result of the cutting pressure by the pressure sensor, and one supporting rod stops,
Only the tip of the other supporting rod faces the ring body, and the cutting blade is swung like a lever around its one end to cut the ring body.

とができる。In this way, the means for swinging the cutting blade around its one end like a lever to cut the ring body, by the synergistic effect of the pull-cutting and the lever effect, the cutting blade has a fixed posture. The ring body can be cut with a force smaller than that of the means for pushing and cutting while keeping the above-mentioned state, and the force applied to the support rod is small, and the drive unit for driving the support rod can be made small. In addition, if the cutting blade is made longer and the distance between the connecting portions of both support rods with respect to the cutting blade is increased,
Due to the principle of leverage, a large force can be applied to the ring body to cut it, so for example, for a large-diameter ring body that requires a large cutting force, it can be dealt with by lengthening the cutting blade to some extent, The drive unit can be downsized.

Since the cutting pressure does not act on the cutting blade 6 at the beginning of driving the cutting machine, the switching valve V is switched to the first state based on the detection result of the pressure sensor 8 that the cutting pressure is smaller than the set value. Drive only hydraulic cylinder S1
By projecting the first support rod 7a from the frame 4a, the second frame 4b is separated from the first frame 4a, and the tire T is kept with the cutting blade 6 in a constant posture.
Send to. The cutting blades 6 are arranged so as to face a plurality of portions of the tire T in the circumferential direction.
Is in a state where it is externally fitted to the truncated cone-shaped ring mounting member 1a and is prevented from moving in a direction away from the cutting blade 6, so that when the cutting blade 6 contacts the tire T, the tire T is clamped between the cutting blade 6 and the base end portion of the ring body mounting member 1a to be in a fixed state (see FIG. 2). When the cutting blade 6 bites into the tire T and the cutting pressure exceeds a set value, the switching valve V is switched to the second state based on the detection result of the cutting pressure by the pressure sensor 8, and the first support rod 7
a is stationary, only the tip of the second support rod 7b faces the tire T, and the cutting blade 6 is swung like a lever around the end of the first support rod 7a to cut the tire T. (See FIG. 3). At this time, the cutting blade 6 moves along with the swing.
The cutting blade of the ring body mounting member 1a enters the relief groove 11 to avoid interference with the ring body mounting member 1a.

きる。Further, in the means for cutting the ring body by swinging the cutting blade 6 around one end thereof like a lever as described above, the means for pushing and cutting while keeping the cutting blade 6 in a fixed posture cuts the ring body. The tire T can be cut with a small force, the force applied to the second support rod 7b can be small, and the second hydraulic cylinder S2 can be small. Further, if the cutting blade 6 is lengthened and the distance between the connecting portions of the support rods 7a and 7b with respect to the cutting blade 6 is widened, a large force can be applied to the tire T to cut it by the lever principle. Therefore, for example, for a tire T having a large diameter that requires a large cutting force, the cutting blade 6 can be made longer to some extent, and the second hydraulic cylinder S2 can be made smaller.

Since the tire T is externally fitted to the truncated cone-shaped ring-body mounting member 1a, the tire T is cut while being pressed to the swing fulcrum side of the cutting blade 6, and is simply placed and fixed on a flat plate. The tire T can be cut more efficiently than when the cutting blade 6 is swung. Further, since the bead portion of the tire T that requires the greatest cutting force can be brought closer to the swing fulcrum side of the cutting blade 6 than other portions of the tire T, the bead portion can be relatively easily cut. .
