固着される。2. Description of the Related Art Conventionally, there is a band saw for cutting a hard material such as stone, and in this type of band saw, a chip is generally fixed to the cutting edge of the band saw.
かかる帯鋸によれば、チップの存在により鋸歯の損耗が
抑制される利点がある。According to such a band saw, the wear of the saw teeth is suppressed by the presence of the tip.

Peeling, etc., makes it difficult to cut properly, and it is necessary to repair the worn tip.However, this tip is usually difficult to repair in the field. There is the inconvenience of having to carry out a great deal of work, such as having to remove it and carry it to a repair shop, and to take the band saw back to reassemble it after the repair is completed.
そこで、上記の問題を解消するために、チップの交換を
現場でなし得るようにしたものとして、特開昭６０−１
２７９１８号公報記載の「チップ歯の取付方法」が開示
されている。Therefore, in order to solve the above-mentioned problems, it is possible to replace the chip on-site, as disclosed in JP-A-60-1.
The "mounting method for tip teeth" described in Japanese Patent No. 27918 is disclosed.

いチップが損傷するなどの問題がある。However, in this case, since the tip mounting piece and the saw blade are attached and detached by the fixing pin and the fitting groove, there is a difficulty in strength. Especially in the case of a band saw, a large horsepower (30
Since it is driven with about horsepower), there is a drawback that the pin is damaged due to the rotation. Further, according to the chip mounting structure using such a chip mounting piece, it is not possible to adapt to the bending that occurs when the blade is curved, and therefore, there is a problem in that distortion occurs and the chip, which is highly brittle, is damaged.

その機能を維持することになる。Action Normally, the band saw 9 is formed in an endless shape, and is rotated by the drive mechanism section. Therefore, the entire band saw 9 is bent in a direction orthogonal to its longitudinal direction. At this time, since the bendable fitting body 21 is relatively displaceable with respect to the chip support 23, the bendable fitting body 21 bends without being constrained, and the joint portion between the fitting body 21 and the main body of the band saw 9 is preferably protected. It On the other hand, the chip support 23 is the fitting body 21.
Is relatively displaceable with respect to the chip support 23, so that it is not affected by the bending of the fitting body 21. As a result, the rigid and brittle tip 19 is preferably protected from the inconvenience caused by the bending. Thus, the band saw 9 preferably maintains its function regardless of the presence of the fitting body 21 and the chip support 23.

支持台２３は常時予備として保管しておく必要がある。When a part of the tip 19 of the band saw 9 is worn, the worn tip 19 is removed together with the tip support 23 to which the tip 19 is fixed while the band saw 9 is still attached to the drive mechanism section. The chip support 23 to which the new chip 19 is fixed only needs to be locked to the fitting body 21. The chip support 23 to which the new chip 19 is fixed must be stored as a spare at all times.

回することとなる。The operation when the band saw 9 having the above configuration is used in a cutting device will be described. When the band saw 9 reaches the peripheral surface of the drive pulley 1 or the floating pulley 7, the band saw 9 is forcibly bent along the peripheral surface. Then, one spherical body fitting portion 25 of the fitting body 21 rotates in the fitting hole 27, and the other spherical body fitting portion 25 rotates in the fitting hole 27 and moves to move the position of the fitting body. 21 is bent by the bending of the body of the band saw 9 without being restricted by the chip support 23. Therefore, even if the main body of the band saw 9 is bent, the chip support 23 does not cause a significant distortion, and the chip 19 having high brittleness is preferably protected. Also, various acting forces on the chip support 23 are different from the fitting hole 2
It is suitably received by the spherical wall 27c of No. 7, the spherical fitting portion 25 of the fitting body 21, the pin 31, and the like. Thus, the band saw 9 orbits the peripheral surface of the drive pulley 1 and the idle pulley 7 without any trouble.

予備のチップ支持台２３を装着すれば良い。If a part of the chips 19 of the band saw 9 is worn, the operator pulls out the pin 31 of the chip support 23 and then presses the chip support 23 in the direction opposite to the circumferential direction of the band saw 9 to form a sphere 25b. The circular tip 27a and the circular hole 27a are pulled out in a state of facing each other, and the spare tip support 23 to which the new tip 19 is welded may be attached in the reverse procedure.

Moreover, since the base side of the fitting body is fixed to the body of the band saw by welding, the band saw driven by a large horsepower can be sufficiently dealt with in terms of strength. As a result, there is an effect that the wear of the chip can be dealt with by a simple operation of only replacing the chip portion.
