捨棄式多刃雕刻刀片 Discarded multi-blade engraving blade

本發明係有關於一種捨棄式雕刻刀片之改良，由指一種雕刻刀片具有多刃之刀刃結構，材料切削移除率高之捨棄式多刃雕刻刀片。 The present invention relates to an improvement of a retractable engraving blade, which is a discarding multi-blade engraving blade having a multi-blade blade structure and a high material removal removal rate.

一般習用之雕刻刀，主要是應用於金屬表面之刻字或是雕刻各式圖樣、花紋……等之加工，請參閱第六~八圖所示，係為一般整支實體碳化物材料之雕刻刀具30，該雕刻刀具30包含刀桿31及雕刻刀刃32兩部分，其中該雕刻刀刃32係由一位於中心線之平坦頂面321、右側邊322、左側邊323所圍之夾角以及於末端設一與水平面至少為5°以上之端切刃324所構成，請參閱第八圖所示為該雕刻刀刃之局部放大圖，該雕刻刀刃32之中心線320與該刀桿中心線310具有一適當之偏心值e，該端切刃324之末端與刀桿中心線310之值為槽寬半徑Y，該雕刻刀所切削之槽寬暨為2Y，該雕刻刀具30由於切削量少，因此主要是藉由該雕刻刀刃32之偏心值e之設計，僅單一右側邊322及末端之端切刃324具有切削能力，暨只有單刃切削之能力，故對材料之移除率較低，通常係運用於0.3mm以下寬度或是深度之淺層刻字、雕刻圖樣…等工作。 The commonly used engraving knives are mainly used for the engraving of metal surfaces or the engraving of various patterns, patterns, etc., please refer to the sixth to eighth figures, which are general engraving tools for solid carbide materials. 30. The engraving tool 30 includes two parts, a shank 31 and an engraving blade 32. The engraving blade 32 is formed by a flat top surface 321 , a right side 322 , and a left side 323 of the center line. The end cutting edge 324 is at least 5° above the horizontal plane. Referring to FIG. 8 , a partial enlarged view of the engraving blade is shown. The center line 320 of the engraving blade 32 and the tool bar center line 310 have a suitable one. The eccentricity value e, the end of the end cutting edge 324 and the center line 310 of the tool holder are the groove width radius Y, and the groove width of the engraving knife is 2Y. The engraving tool 30 mainly borrows due to the small amount of cutting. Due to the design of the eccentric value e of the engraving blade 32, only the single right side 322 and the end end cutting edge 324 have the cutting ability, and only the single-edge cutting ability, so the removal rate of the material is low, and is usually applied to Width or depth below 0.3mm Shallow lettering, engraved pattern ... and so on.

請參閱第九圖所示，係為捨棄式結構之雕刻刀具40，該捨棄式刀具之刀桿41末端設一刀座42，該刀座42之螺孔421中心位置與刀桿中心線400具有一微小之偏離值e，該刀座42上得鎖一捨棄式雕刻刀片50，該捨棄 式雕刻刀片50係呈一菱形之外觀，其一端設有一右切邊51及一左切邊52包夾成一V形狀，該V形狀末端設有一端切刃53，該左切邊52與右切邊51係呈對稱狀，末端之交點並位於刀片之中心線500上，以及該刀片供鎖固之階級孔54係位於捨棄式雕刻刀片50之中心位置；因此當捨棄式雕刻刀片50鎖固於刀座42時，該端切刃53之刀尖與刀桿中心線400具有一槽寬半徑Y，且僅單一側之右切邊51及端切刃53具有切削能力，因此該捨棄式雕刻刀片50只有單刃切削之能力，對材料之移除率僅靠轉速於以提升，通常係運用於0.3mm以下寬度或是深度之淺層刻字、雕刻圖樣…等工作。 Referring to FIG. 9 , the engraving tool 40 of the discarding structure is provided with a knife seat 42 at the end of the cutter shaft 41 of the discarding tool. The center position of the screw hole 421 of the tool holder 42 has a center line 400 with the tool holder center line 400. A slight deviation value e, the knife holder 42 is locked with a discarded engraving blade 50, which is discarded. The engraving blade 50 has a diamond-shaped appearance, and has a right-cut side 51 and a left-cut side 52 at one end thereof, and is formed into a V shape. The V-shaped end is provided with a cutting edge 53 at the end, and the left cutting edge 52 and the right cutting edge are provided. The side 51 is symmetrical, the intersection of the ends is located on the centerline 500 of the blade, and the blade-type locking hole 54 is located at the center of the retractable engraving blade 50; thus, when the retractable engraving blade 50 is locked When the blade holder 42 is used, the blade edge of the end cutting edge 53 and the blade center line 400 have a groove width radius Y, and only the right side of the right cutting edge 51 and the end cutting edge 53 have cutting ability, so the discarded engraving blade 50 has the ability of single-edged cutting. The removal rate of the material is only increased by the speed. It is usually used for shallow lettering and engraving patterns with a width of 0.3mm or less.

由於前述兩種雕刻刀具僅具有單刃切削之能力，如果對寬度較大且深度較深(大於0.3mm)之雕刻作業則雕刻速度較為緩慢，且需要較多加工之時間，此外，習用雕刻刀刃之頂面係位於旋轉中心，如第七圖所示，該雕刻刀刃32之平坦頂面321係位於中心線上，另一側無任何實體，僅右半邊具有實體，可供作為刀刃之用，在高速旋轉下會有震動之現象，故此類之刀具無法高速切削；又，請參閱第六、八圖所示，藉由該雕刻刀刃32之偏心值e之設計，僅單一右側邊322及末端之端切刃324具有切削能力，暨只有單刃切削之能力，也因為只有單刀刃具切削能力，對材料之移除率為一般常見刀具之一半，是故，該刀具的經濟效益較低，很明顯地對生產及加工速度無法提升。 Since the above two kinds of engraving tools only have the ability of single-blade cutting, if the engraving work with a large width and a deep depth (greater than 0.3 mm) is slower in engraving and requires more processing time, in addition, the engraving blade is used. The top surface is located at the center of rotation. As shown in the seventh figure, the flat top surface 321 of the engraving blade 32 is located on the center line, and the other side has no solid body, and only the right half has a solid body, which can be used as a blade. There is vibration under high-speed rotation, so such tools cannot be cut at high speed; also, as shown in Figures 6 and 8, by the design of the eccentricity e of the engraving blade 32, only a single right side 322 and the end The end cutting edge 324 has the cutting ability, and has the ability of single-blade cutting. Because only the single-blade cutting ability is available, the removal rate of the material is one-and-a-half of the common tools. Therefore, the economic benefit of the cutting tool is low. The production and processing speed of the ground cannot be improved.

刀刃口使用一段時間後必會有鈍化現象，由於雕刻刀刃口非常小，磨削必須非常準確才不致於發生偏心量過大之現象，故磨削技術高且常會磨削錯誤之情形，在人才逐漸流失以及技術人員年齡老化後視力無法負擔如此微小尺寸之磨削作業，故習用整支實體碳化物材料之雕刻刀具 越來越少人使用，而改用捨棄式雕刻刀片，直接更換刀片無須磨削刀刃口，然而僅有單刀刃之捨棄式刀片僅視合用於0.3mm以下之雕刻；至於寬度較大之雕刻(0.3mm以上)者仍使用單刀刃刀片加工時，由於速度無法提升，移除率無法增加，刀刃之磨損卻倍增，刀刃負荷增加，對刀刃之磨耗就顯得非常明顯。 After the blade is used for a period of time, there will be a passivation phenomenon. Since the cutting edge of the engraving blade is very small, the grinding must be very accurate so as not to cause an excessive eccentricity. Therefore, the grinding technique is high and the grinding error is often caused. The loss and the technician's age can not bear the grinding operation of such a small size after ageing, so the engraving tool of the whole solid carbide material is used. Less and less people use it, instead of using a discarding engraving blade, the blade can be directly replaced without grinding the blade edge. However, the single-blade discarding blade is only used for engraving of 0.3mm or less; as for the engraving with a larger width ( When the single-blade insert is used for machining, the removal rate cannot be increased, the wear of the blade is doubled, the blade load is increased, and the wear of the blade is very obvious.

習知雕刻刀具僅具有單刃切削之能力，故對材料之移除率較低，如果對寬度較大且深度較深之雕刻作業則雕刻速度較為緩慢，且需要較多加工之時間，同時刀刃之磨損卻倍增，刀刃負荷增加，對刀刃之磨耗就顯得非常明顯。 Conventional engraving tools only have the ability to cut by a single blade, so the removal rate of the material is low. If the engraving operation is large and deep, the engraving speed is slow, and more processing time is required, and the cutting edge is required. The wear is multiplied, the blade load is increased, and the wear on the blade is very obvious.

本發明捨棄式多刃之雕刻刀片，該雕刻刀片之兩端設為對稱之V形狀，分別由右側面及一左側面包夾成者，該V形狀末端兩斜向對應面分別設有一排屑槽，該排屑槽底面之切削面係與刀片之旋轉軸相交，使得該使得該切削面與右側面形成右切邊，與左側面形成左切邊，形成多(至少為二個)刀刃口之捨棄式雕刻刀片。 The retractable multi-blade engraving blade of the present invention has a symmetrical V shape at both ends thereof, and is respectively formed by a right side surface and a left side bread, and the V-shaped end has two flutes respectively corresponding to the obliquely corresponding surfaces. The cutting surface of the bottom surface of the chip flute intersects with the rotating shaft of the blade such that the cutting surface forms a right cut edge with the right side surface and a left cut side with the left side surface to form a plurality of (at least two) cutting edges. Discard engraving blade.

本發明在捨棄式雕刻刀片之末端設有多刃切邊(至少二個切邊)，有別於習用者僅設有單一切邊，得以倍增材料之移除率，改變習用捨棄式雕刻刀具設計之形態，雕刻作業時間得以減少以及提升產能等進步功效，此一結構設計乃為雕刻刀具業界之首創。 The invention has a multi-edge trimming edge (at least two trimming edges) at the end of the discarding engraving blade, which is different from the conventional one in that only a single side is provided, which can multiply the removal rate of the material and change the design of the conventional discarded carving tool. The shape, the engraving time is reduced and the productivity is improved. This structural design is the first in the engraving tool industry.
