Description
【考案の詳細な説明】
本考案は、チップ付ルータ錐の改良に関するもので、特
にその補強に係るものである。[Detailed Description of the Invention] The present invention relates to an improvement of a router cone with a tip, and particularly to its reinforcement.
従来チップ付ルータ錐は、切削作業中にクラックが入っ
たり、あるいは折損事故が生じ易い等の欠点があった。Conventional tipped router drills have had drawbacks such as cracking or breakage during cutting operations.
特にNC付ルータ錐については、切削量が多いほか材の
送りが機械的に行なわれているため、刃が摩耗して送り
が重くなっても人手による場合のように加減せず、その
ままの速さで進むため折損事故が多かった。In particular, with NC router drills, the amount of cutting is large and the feed of the material is done mechanically, so even if the blade wears and the feed becomes heavy, it cannot be adjusted as it would be manually, and the speed remains the same. There were many breakage accidents as the train moved slowly.
しかしこれらの事故原因を検討してみると、その殆んど
が切屑用の進講1の切上り部分2付近に生じていた。However, when we examined the causes of these accidents, we found that most of them occurred near the cut-up section 2 of the cutting section 1 for chips.
(第1〜2図参照)この理由は、チップ3と合金部との
物理的強度が同一でないこと、及び切削作業時に大きな
応力がかかるシャンク部4との境付近まで、切屑用の進
講1があるためこの部分が細くなっているからである。(See Figures 1 and 2) The reason for this is that the physical strength of the chip 3 and the alloy part are not the same, and that the cutting edge 1 is This is because this part is thinner.
本考案は、この折損事故を防止するために提案したもの
で、チップをシャンク部方向に延長して、その長さを切
屑用の進講より長くして補強することにより解決しよう
とするものである。The present invention was proposed in order to prevent this breakage accident, and attempts to solve this problem by extending the insert in the direction of the shank and making the length longer than that for cutting chips and reinforcing it. .
以下実施例を図面に基いて説明すると、第3〜4図に於

うち一方のチップ11をシャンク部13方向へ延長して
、その長さを進講12より長くして進講12の切上り部
分14を補強したものである。The embodiment will be described below with reference to the drawings. In FIGS. 3 and 4, 11 is a tip and 12 is a tip for cutting chips. One of the tips 11 is extended in the direction of the shank portion 13. Its length is made longer than that of the advancing section 12, and the cut-up portion 14 of the advancing section 12 is reinforced.
尚延長するチップは、この実施例のように一方に限るも
のではなく、両方のチップを延長してもよいことはいう
迄もない。Note that the number of tips to be extended is not limited to one as in this embodiment, and it goes without saying that both tips may be extended.
本考案は、このようにチップをシャンク部方向に延ばす
ことにより大きな応力がかかる進講の切上り部分を補強
したので、ルータ錐の折損事故の防止のうえで大きな効
果を生ずるものである。In this invention, by extending the tip in the direction of the shank portion, the cut-up portion of the protrusion, which is subject to large stress, is reinforced, which is highly effective in preventing breakage accidents of the router drill.
