【発明の詳細な説明】
［産業上の利用分野］
この発明は、花崗岩、大理石、ガラス、超硬合金、陶器
そしてタイル、半導体、セラミックス等の硬質物又は各
種金属を切削（切断を含む）するための硬質物切削用帯
のこに関するものであり、更に詳しく言えば、一対の回

の硬質物切削用帯のこに関するものである。[Detailed Description of the Invention] [Industrial Application Field] This invention is suitable for cutting (including cutting) hard materials such as granite, marble, glass, cemented carbide, ceramics, tiles, semiconductors, ceramics, etc., or various metals. The present invention relates to a band saw for cutting hard materials, and more specifically, to an endless continuous band saw for cutting hard materials that is tensioned by a pair of rotatable drums.
〔従来の技術］
一般に、主として硬質物の切削に使用される帯のこは、

状（エンドレス）に形成され、軸間を調節できる一対の
回動自在なドラムに掛渡して、その軸間調節により緊張
させた後に回転させて使用している。[Prior Art] Band saws are generally used mainly for cutting hard materials.
Slits are made at equal intervals in a strip made of thin steel plate, etc.
A notch is provided between the slits, and a cube or other chip made of a sintered alloy containing diamond abrasive grains is embedded in the notch so that about half of the chip protrudes, and then this is soldered with silver solder, etc. In order to improve cutting efficiency and cutting accuracy, band saws are formed into an endless series and hung on a pair of rotatable drums that can adjust the distance between the shafts. It is used by handing it over, tensioning it by adjusting its axis, and then rotating it.
この帯のこの緊張は、その帯条板の刃部がドラムと当接
できない為にドラムの端より突出していること及び、帯
条板の中央部である腰部と側端部である背部及び刃部と
では緊張した時の延び率が相違し、その延びの差によっ
て刃部に歪みが発生する。This tension in the band is due to the fact that the blade of the band cannot come into contact with the drum, so it protrudes from the edge of the drum, and the waist, which is the central part of the band, and the back and blade, which are the side ends, of the band. The elongation rate under tension is different between the two parts, and the difference in elongation causes distortion in the blade part.
即ち、緊張時は、帯条板の腰部が刃部及び背部より多く
延びることによって、刃部に波打ち現象が表われる又は
内側に反る等の歪みが発生する。That is, when the belt is under tension, the waist of the strip extends more than the blade and the back, causing distortion such as waving or inward warping of the blade.
そして、硬質物は、通常の金属等より高価であるのでよ
り切削代を少なくする必要があると共に、極薄に切断す
る等の精密に切削する必要もあり１．上記刃部の歪みの
防止は最重要なものである。Hard materials are more expensive than ordinary metals, so it is necessary to reduce the cutting allowance, and it is also necessary to cut them precisely, such as by cutting them into extremely thin pieces.1. Prevention of the distortion of the blade is of the utmost importance.
そこで従来、帯条板の腰部にローラを押圧し予め腰部を
刃部や背部より圧延して緊張時の刃部の歪みを防止した
硬質物切削用帯のこがある。Conventionally, there is a band saw for cutting hard materials in which a roller is pressed against the waist of a strip plate and the waist is rolled from the blade or back in advance to prevent distortion of the blade when tensioned.
［発明が解決しようとする課題］
このような従来技術においても一応は刃部の歪みの発生
は防止できるのであるが、そのローラの押圧作業が容易
でないという問題点がある即ち、−度のローラの押圧で
は所望量の圧延ができないので通数口繰り返さなければ
ならずまた、圧延量を均一で正確にするには高度に熟練
した技ｆ＋７を要する等の問題点がある。[Problems to be Solved by the Invention] Although it is possible to prevent the occurrence of distortion in the blade part in this conventional technique, there is a problem in that it is not easy to press the roller. Since it is not possible to roll the desired amount by pressing , it is necessary to repeat the process several times, and there are other problems such as the need for highly skilled skill f+7 to make the amount of rolling uniform and accurate.
更に、使用により延びが戻る、あるいは緊張度によって
も延びの戻り量が変化する等の問題点がある。Furthermore, there are problems in that the elongation returns with use, or that the amount of elongation return changes depending on the degree of tension.
本発明は、従来技術の有するこのような問題点に鑑みて
なされたものであり、その目的とするところは、簡単な
構造において正確に緊張時の刃部の歪みを防止し、より
精密に切削できる硬質物切削用帯のこを提供しようとす
るものである。The present invention was made in view of the above-mentioned problems of the prior art, and its purpose is to accurately prevent distortion of the blade part during tension with a simple structure, and to achieve more precise cutting. The purpose of this invention is to provide a band saw for cutting hard materials.
［課題を解決するための手段］

特徴としてなるものである。[Means for Solving the Problems] In order to achieve the above object, the band saw for cutting hard materials of the present invention has a blade portion formed at one end of a band plate, which is tensioned by a pair of drums. The endless continuous band saw used for cutting hard materials is characterized by having a large number of holes in the waist part that comes into contact with the drum to prevent the blade from becoming distorted when tensioned. .
［作用］
孔の大きさ及び数すなわち腰部の孔の総面積によって、
腰部の延び率が変化する。[Effect] Depending on the size and number of holes, that is, the total area of the holes in the waist,
The elongation rate of the waist changes.
よって、帯条板の厚さ、ドラムよりの刃部の突出量そし
て緊張度などの使用条件を考慮して孔の大きさ及び数を
決定すれば、緊張時にその腰部は、不要な延びを吸収す

た、多数の孔は、帯条板の重量を軽減すると共に、ドラ
ムとの滑りを防止し、しかも空気や切削油または冷却水
等の流通が良くなるので切削による発熱を防止する。Therefore, if the size and number of holes are determined in consideration of usage conditions such as the thickness of the strip, the amount of protrusion of the blade from the drum, and the degree of tension, the waist part will absorb unnecessary elongation when tensioned. And since it is not deformed like rolling, etc., its elongation rate does not change.In addition, the large number of holes reduces the weight of the strip and prevents it from sliding against the drum. In addition, it improves the circulation of air, cutting oil, cooling water, etc., thereby preventing heat generation due to cutting.
更に、それぞれの孔には、切削油等が付着するごとく保
持されると共に、切削屑も保持できるので、切削部への
給油及び切削屑の搬出が良好となる。Furthermore, each hole retains cutting oil and the like as if it were attached to it, and can also retain cutting waste, so that oil supply to the cutting part and removal of cutting waste are facilitated.
