Description
本考案は高切削屑排出ドリルに関し、特に鑽孔作業において、切削屑排出溝の巡らす回数の増加によって、切削屑排出溝末端の総容積を大幅に増加し、切削屑排出効果を向上できるドリルに関する。 The present invention relates to a high cutting waste discharging drill, and more particularly to a drill capable of significantly increasing the total volume of the cutting waste discharge groove end and increasing the cutting waste discharge effect by increasing the number of times the cutting waste discharge groove is circulated in a drilling operation. .
図１に示す公知技術のドリルの構造はシャンク部４を有し、シャンク部４の末端部は刃部３を延設され、刃部３の末端は静止点３１を設けられ、静止点３１の両側は切削刃３２を形成し、各切削刃３２の一側は、それぞれシャンク部４向きに巡らしてピッチが一致する切削屑排出溝３３を凹設する。 1 has a shank portion 4, the end portion of the shank portion 4 is extended with a blade portion 3, and the end of the blade portion 3 is provided with a stationary point 31. The cutting blades 32 are formed on both sides, and one side of each cutting blade 32 is provided with a cutting waste discharge groove 33 having a pitch matching around the shank portion 4.
よって、切削刃３２の数が多いほど、切削屑排出溝３３の数も多くなり、刃部３の横断面積も相対的に小さくなる。それのため、刃部３全体の強度を相対的に低下させ、ドリルによる鑽孔作業のときは引き下げてバイトを仕送るときに、刃部３が曲げ変形を引き起して、中心位置の振れ及び穴部の拡大を発生し、鑽孔精度を極端に低下される。 Therefore, the greater the number of cutting blades 32, the greater the number of cutting waste discharge grooves 33, and the cross-sectional area of the blade portion 3 is also relatively small. For this reason, the strength of the entire blade portion 3 is relatively lowered, and when the drill is drilled, the blade portion 3 causes a bending deformation when the cutting tool is pulled down to feed the cutting tool. In addition, the hole portion is enlarged and the fistula accuracy is extremely lowered.
本考案の主な目的はドリルの切削屑排出溝末端の総容積を増加することによって、ドリルの先端に備える２つの切削屑排出溝が末端の高容積の切削屑排出溝と交差したときに、より良い切削屑の排出効果を達成する。 The main object of the present invention is to increase the total volume at the end of the cutting waste discharge groove of the drill, so that when the two cutting waste discharge grooves provided at the tip of the drill intersect with the high volume cutting waste discharge groove at the end, Achieve better chip removal effect.
前述目的を達成するため、本考案による高切削屑排出ドリルは刃部を有し、刃部の末端は静止点を有する。刃部が静止点の遠端側にシャンク部を連接され、刃部の末端に備える静止点一側は斜め向きに第１切削刃を形成し、他側は斜め向きに第２切削刃を形成する。第１切削刃にてシャンク部向きに巡らす第１切削屑排出溝を凹設され、第２切削刃にてシャンク部向きに巡らす第２切削屑排出溝を凹設され、第１切削屑排出溝のピッチは等距離にてシャンク部向きに巡らし、第２切削屑排出溝のピッチはシャンク部向きに距離を変えて巡らすことによって、第１切削屑排出溝がシャンク部向きに適切な位置を巡らした後、第２切削屑排出溝との交差する場所にて、シャンク部側向きに巡らす第３切削屑排出溝を形成する。第３切削屑排出溝のピッチは刃部からシャンク部に向かって、次第に縮小し、第３切削屑排出溝の容積を増加させ、より良い切削屑の排出効果を達成する。 In order to achieve the above object, the high cutting waste discharging drill according to the present invention has a blade portion, and the end of the blade portion has a stationary point. The blade part is connected to the shank part on the far end side of the stationary point, one side of the stationary point provided at the end of the blade part forms a first cutting blade in an oblique direction, and the other side forms a second cutting blade in an oblique direction. To do. A first cutting waste discharge groove is formed in the first cutting blade toward the shank portion, and a second cutting waste discharge groove is provided in the second cutting blade in the direction of the shank portion to provide a first cutting waste discharge groove. The pitch of the second cutting waste is circulated toward the shank portion at an equal distance, and the pitch of the second cutting waste discharge groove is changed by changing the distance toward the shank portion, so that the first cutting waste discharge groove goes around an appropriate position toward the shank portion. Then, the 3rd cutting waste discharge groove | channel which goes around to the shank part side is formed in the place which cross | intersects with the 2nd cutting waste discharge groove. The pitch of the third cutting waste discharge groove is gradually reduced from the blade portion toward the shank portion to increase the volume of the third cutting waste discharge groove, thereby achieving a better cutting waste discharge effect.
以下、添付図面を参照して本考案の実施の形態を詳細に説明する。 Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
図２と図３を参照する。図から明かのように、本考案の高切削屑排出ドリルによるドリル１０は刃部１を備え、刃部１の末端は静止点１１を有し、刃部１が静止点１１の遠端側にシャンク部２を有する。刃部１の末端は静止点１１の一側にて斜め向きに第１切削刃１２を形成し、他側は斜め向きに第２切削刃１３を形成する。第１切削刃１２にてシャンク部２向きに巡らす第１切削屑排出溝１４を凹設され、第２切削刃１３にてシャンク部２向きに巡らす第２切削屑排出溝１５を凹設され、第１切削屑排出溝１４のピッチはシャンク部２向きに等距離にて巡らし、第２切削屑排出溝１５のピッチはシャンク部２向きに距離を変更して巡らすことによって、第１切削屑排出溝１４がシャンク部２向きに適切な位置を巡らした後、第２切削屑排出溝１５と交差し結合して、シャンク部２側に巡らす第３切削屑排出溝１６を形成する。第３切削屑排出溝１６のピッチ角度は３０から７５度の間で次第に増加して、第３切削屑排出溝１６のピッチは刃部１からシャンク部２に向かって次第に縮小して、第３切削屑排出溝１６の容積を増加し、第３切削屑排出溝１６の幅が第１切削屑排出溝１４に等しいかまたは大きくすることによって、本考案のドリル１０を形成する。 Please refer to FIG. 2 and FIG. As is clear from the figure, the drill 10 by the high cutting waste discharging drill of the present invention has a blade portion 1, the end of the blade portion 1 has a stationary point 11, and the blade portion 1 is on the far end side of the stationary point 11. It has a shank part 2. The end of the blade portion 1 forms a first cutting blade 12 obliquely on one side of the stationary point 11 and the second cutting blade 13 obliquely on the other side. The first cutting blade 12 is recessed with a first cutting waste discharge groove 14 that runs around the shank portion 2, and the second cutting blade 13 is recessed with a second cutting waste discharge groove 15 that runs around the shank portion 2, The pitch of the 1st cutting waste discharge groove 14 circulates at equal distance toward the shank part 2, and the pitch of the 2nd cutting waste discharge groove 15 changes the distance toward the shank part 2, and the 1st cutting waste discharge After the groove 14 travels to an appropriate position in the direction of the shank portion 2, it intersects with the second cutting waste discharge groove 15 and joins to form the third cutting waste discharge groove 16 that goes around the shank portion 2. The pitch angle of the third cutting waste discharge groove 16 is gradually increased between 30 and 75 degrees, and the pitch of the third cutting waste discharge groove 16 is gradually reduced from the blade portion 1 toward the shank portion 2, The drill 10 of the present invention is formed by increasing the volume of the cutting waste discharge groove 16 and making the width of the third cutting waste discharge groove 16 equal to or larger than the first cutting waste discharge groove 14.
使用者が本考案のドリル１０を使用して、工作物（図示しない）の鑽孔作業を行うときは、刃部１の末端を工作物の表面にあてがい、刃部１末端に備える第１切削刃１２と第２切削刃１３によって、工作物の表面を切削する。第１切削刃１２と第２切削刃１３の切削によって形成される切削屑はそれぞれ第１切削刃１２と第２切削刃１３の一側に設けられた第１切削屑排出溝１４と第２切削屑排出溝１５を介して、第３切削屑排出溝１６に排出した上、引き続き第３切削屑排出溝１６より、刃部１の外部に排出させ、より良い切削屑の排出効果を達成する。 When a user performs a drilling operation of a workpiece (not shown) using the drill 10 of the present invention, the first cutting is performed by placing the end of the blade 1 on the surface of the workpiece and providing the end of the blade 1. The surface of the workpiece is cut by the blade 12 and the second cutting blade 13. The cutting waste formed by the cutting of the first cutting blade 12 and the second cutting blade 13 is the first cutting waste discharge groove 14 provided on one side of the first cutting blade 12 and the second cutting blade 13 and the second cutting, respectively. After being discharged to the third cutting waste discharge groove 16 through the waste discharge groove 15, it is continuously discharged from the third cutting waste discharge groove 16 to the outside of the blade portion 1 to achieve a better cutting waste discharge effect.
よって、本考案は公知技術の不足ならび欠点を解決できる技術ポイントは、本考案による第３切削屑排出溝１６のピッチは刃部１からシャンク部２向きに次第に縮小し、第３切削屑排出溝１６がドリル１０を巡らす巻き数が増加したため、第３切削屑排出溝１６の長さも増加したことで、第３切削屑排出溝１６の容積も増加する。よって、第１切削屑排出溝１４と第２切削屑排出溝１５からの切削屑を同時に排出でき、より良い切削屑の排出効果を達成できる。 Therefore, the technical point that the present invention can solve the deficiencies and disadvantages of the known technology is that the pitch of the third cutting waste discharge groove 16 according to the present invention is gradually reduced from the blade portion 1 toward the shank portion 2, and the third cutting waste discharge groove. Since the number of windings 16 around the drill 10 increases, the length of the third cutting waste discharge groove 16 also increases, so that the volume of the third cutting waste discharge groove 16 also increases. Therefore, the cutting waste from the 1st cutting waste discharge groove 14 and the 2nd cutting waste discharge groove 15 can be discharged simultaneously, and the discharge effect of the better cutting waste can be achieved.
