本発明は、シャンクの先端部にダイヤモンドチップ、超
硬チップ等の刃先を溶着した刃物の刃先冷却法に関する
。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method for cooling the cutting edge of a cutter having a cutting edge such as a diamond tip or a carbide tip welded to the tip of the shank.
従来、ダイヤモンドチップ、超硬チップ等の刃先を溶着

に手数を要するといった不具合点がある。特に屋内での
改装作業等では斯かる汚れはｆ！端にさられれ、乾式状
態のまま作業せざるを得ない場合が増加しつつある。Conventionally, when cutting a blade such as a diamond tip or a carbide tip, the welded part of the blade becomes hot, the welded part of the blade melts, and the tip may fall off. To prevent this, oil or water is poured onto the cutting edge to remove cutting heat.
The temperature rise was suppressed. This method has disadvantages in that the work surface is inevitably contaminated with water and the like, and it takes time and effort to remove it. Especially when doing renovation work indoors, such dirt is f! Increasingly, workers are forced to work in dry conditions.
本発明は前述した不具合点をなくして１作業面が冷却液
により汚されることなくかつ、刃先部は切削熱による温
度上昇を防止出来る刃物を提供することである。The object of the present invention is to provide a cutting tool which eliminates the above-mentioned disadvantages, prevents one working surface from being contaminated by cooling fluid, and prevents the cutting edge from rising in temperature due to cutting heat.

るよう工夫したものである。That is, the present invention forms a cutting edge portion by welding a cutting edge such as a diamond tip or a carbide tip to the tip of the shank,
This is a cutting tool that performs cutting work using the cutting edge, and is designed to cool the cutting edge such as a diamond chip and its turbid part by forming a circulation flow path for a cooling fluid inside the cutting edge to cool the cutting edge. It is.
以下１本発明を図示実施例により詳述する。 The present invention will be explained in detail below with reference to illustrated embodiments.

、冷却用流体が充満し、ここから折返えして循環する。Figure 1 is a longitudinal cross-sectional side view of the cutting edge of the knife according to the present invention.
In the figure, reference numeral 1 denotes a hollow cylindrical cutter body, and inside its shank portion 2 are a plurality of pairs of circulation channels 3, 3, 4, 4, 4, 4, 4, 4, 3, 4, 4, 4, 3, 4, 4, 4, 3, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 3, 4, 4 . are bored parallel to the axis, 3 of which are the outgoing path @recirculation path connected to the cooling liquid supply device (not shown), and 4 is the return path connected to the cooling liquid recovery device (not shown). be. 5 is a copper plate and shank 2
-S is welded to the lowest end of the shank 2, and -S
The end face 6 of the shank 2 has a circulation passage 3,
A ring-shaped groove 7 communicating with 3, 4, and 4 is carved, and is filled with a cooling fluid, from which the cooling fluid is circulated.
銅板５の他端面８には、チップ９，９・・・が溶着され
ている。１０は切刃部でチップ９の回転円周とほぼ直角
な面上に形成されている。Chips 9, 9, . . . are welded to the other end surface 8 of the copper plate 5. A cutting edge 10 is formed on a surface substantially perpendicular to the rotational circumference of the tip 9.
従って、冷却液が循環流路の往路３，３から供給される

冷却効果は上昇する。又循環流路３，３，４．４の数が
多い程その冷却効果が増加するから適宜回収熱量に応じ
その数を設定すれば最適条件が得られるものである。Therefore, when the coolant is supplied from the outward paths 3, 3 of the circulation flow path, it enters the ring groove 7 of the copper plate 5, and through this copper plate 5, the heat of the welded parts and chips 9 on both end surfaces 6, 8 is absorbed. The liquid flows while taking away the liquid, enters the adjacent return paths 4, 4, turns back toward the cooling liquid recovery device, and circulates. At this time, if the cross-sectional area of the ring groove 7 is increased so that the cooling liquid flows in contact with the inside of the ring groove 7, the cooling effect will be increased. Moreover, the cooling effect increases as the number of circulation channels 3, 3, 4.4 increases, so optimal conditions can be obtained by appropriately setting the number according to the amount of recovered heat.

できるという効果を奏することができる。As described above, according to the present invention, since the cooling fluid that cools the cutting edge is circulated inside the cutting edge, the cutting edge can be cooled without the cooling fluid leaking out to the outside. It is possible to achieve the effect of realizing an electrically safe and long-life cutlery without causing any damage.
