行されてその研削作用で物品8を一挙に多数個の薄片に
切断する。It is known that one of the methods for cutting thin objects is to run a small-diameter object in one direction, attach abrasive grains and bite into the object, and cut by the abrasive action of the abrasive grains. In order to improve the work efficiency in this cutting technique, for example, as schematically shown in Fig. 3, the scrap @4 is wound around three multi-groove pulleys 1, 2, and 3 arranged in parallel and triangularly. At the same time, both ends of the wire are wound around two bobbins 5.6, and the article 8 is bitten into a steel wire 'A which runs parallel to each other in one direction between two multi-groove pulleys 1.2. Abrasive grains are dropped from a nozzle 7 installed on the opposite side.When the steel wire 4 finishes paying out from one bobbin 15, it is reversed and fed out from the other bobbin 6, making it reciprocate. The abrasive grains that fall onto the article 8 adhere to the steel wire 4 and are carried along, and their grinding action cuts the article 8 into a large number of thin pieces at once.
前記のような多重鋼線式切断装置(マルチワイヤソー)
K要求される問題点として第一に切断能率の向上、第二

第三に多溝滑車の寿命向上などが挙げられろ。第二。Multiple steel wire cutting device (multi-wire saw) as mentioned above
K Required issues include firstly improving cutting efficiency, secondly preventing wire breakage when reversing the steel wire and equalizing tension during cutting.
Thirdly, the lifespan of multi-groove pulleys can be improved. second.
第三の問題点は機構上の問題であるが、第一の問題点は
砥粒の研削作用が重要な要素となる。The third problem is a mechanical problem, but the first problem involves the grinding action of the abrasive grains.
即ち、全切断個所に亘って砥粒が絶えず供給されている
ことが必要であるが、犬ぎい切断面の物品の場合には前
記第3図のように砥粒を物品表面上で自然流下させる方
式では。That is, it is necessary that abrasive grains are constantly supplied to all the cutting points, but in the case of articles with dog-edge cut surfaces, the abrasive grains are allowed to flow down naturally on the surface of the article as shown in Fig. 3 above. In the method.
第4図に示すように鋼線径とほぼ等しい幅の切削溝SI
C砥粒Aが浸入しに<<、物品Mの中心部は鋼線Wのみ

の向上を計ることは到底望めない。更に、余分の砥粒が
物品Mから落下し或いは鋼線Wの走行に伴って飛散し作
業環境を悪化させろという問題もある。As shown in Fig. 4, the cutting groove SI has a width approximately equal to the steel wire diameter.
Since the C abrasive grains A penetrate <<, the central part of the article M is cut only by the steel wire W. For this reason, it is necessary to run the steel 1w at a low speed to entrain and block the abrasive grains A, and at the same time to prevent abnormal generation of frictional heat, and to prevent the inconvenience of rough cut surfaces and breakage of the steel wire. There is no hope of improving cutting efficiency. Furthermore, there is also the problem that excess abrasive grains fall from the article M or scatter as the steel wire W runs, deteriorating the working environment.
そこで2本発明は大きい切断面の物品のぎわめて狭い切
削溝にも砥粒が充分没入し且つ周囲に飛散する心配のな
い、従って高い切断能率で切断が行なえる多重鋼線式切
断装置を提供することを口重として発明されたものであ
る。Therefore, the present invention provides a multiple steel wire cutting device that allows abrasive grains to fully immerse into the extremely narrow cutting grooves of articles with large cutting surfaces, without worrying about scattering to the surroundings, and therefore cutting with high cutting efficiency. It was invented with the aim of providing.
本発明は、二つの多溝滑■の間で互いに平行に並び一方
向へ走行する1機が横断しており且つこの鋼線によって
切断される物品を収容する開放可能な密閉形の切断室と
、この切断室に砥粒を正圧状態で送入する供給機構と。The present invention has a cutting chamber which is parallel to each other and runs in one direction and traverses between two multi-groove slides, and which has an openable closed cutting chamber that accommodates the article to be cut by the steel wire. and a supply mechanism that feeds abrasive grains into the cutting chamber under positive pressure.
前記切断室から砥粒を送出する排出機構、前記1GK物
品を喰込ませる加圧機構とを具えた構成としたことによ
り前記問題点を解決するための手段とした。A means for solving the above-mentioned problems is achieved by adopting a configuration that includes a discharge mechanism that sends abrasive grains out of the cutting chamber, and a pressure mechanism that bites into the 1GK article.

物品を取出して次の物品を収容する。No action! The article is stored in the fI plan, sealed, and the low grains are fed through the supply mechanism until at least the steel wire is buried. Then, the steel wire is moved steadily and the load is applied by the pressure mechanism. The article is gradually bitten into the steel wire and cut. At this time, since the abrasive grains are under positive pressure, they enter the cutting grooves formed in the article and are supplied to all the cutting locations, performing a grinding action as the steel wire travels. After cutting, the abrasive grain is discharged from the cutting chamber by the abrasive discharge mechanism, and the cutting chamber is opened to take out the cut article and store the next article.
切断作業中に砥粒を排出機構により少しずつ排出しなが
ら供給機構により少しずつ補給することてよって砥粒を
切断案内で流動させ常に新しい砥粒で研削作用を行なわ
せることもある。During the cutting operation, the abrasive grains may be discharged little by little by the discharge mechanism and replenished little by little by the supply mechanism, so that the abrasive grains flow along the cutting guide and the grinding action is always performed with new abrasive grains.
本発明によると砥粒な正圧状態で切、析119所^、供

で行なわせることかでき、且つラッピング仕上げと同程
度の切断面が得られるのである。According to the present invention, since the abrasive grains are cut and analyzed in 119 places under positive pressure, they can sufficiently penetrate into even the very narrow cutting grooves of the article and perform the grinding action at all the cut places. . Therefore, even with large cut surfaces, the steel wire can be run at high speed and cut by the grinding action of the abrasive grains with high efficiency without the risk of wire breakage, and a cut surface comparable to that achieved by lapping can be obtained. It will be done.
また、密閉形の切断室に砥粒を供給しその中で切断を行
なうので、砥粒の落下や飛散による損失がなくなるばか
りか作業環境を悪化させる心配もなくなるものである。Further, since abrasive grains are supplied to a closed cutting chamber and cutting is performed therein, not only is there no loss due to falling or scattering of abrasive grains, but there is also no fear of deteriorating the working environment.
