Description
本發明係有關於一種鑽頭或打撃工具等、安裝有超硬合金或陶瓷等之突出部(tip)(以下、稱為「硬質突出部」)之工具(以下、稱為「超硬工具」)中之硬質突出部之固定方法。 The present invention relates to a tool such as a drill or a snoring tool to which a tip (hereinafter referred to as a "hard projection") such as a cemented carbide or ceramic is attached (hereinafter referred to as "super hard tool"). The method of fixing the hard protrusion in the middle.
用於鑽頭或石工之表面加工用工具等多半於鋼製之底材植設硬質(一般為超硬突出部)者。該硬質突出部之安裝法最一般的是於底材穿設供硬質突出部嵌合之安裝孔，並於該安裝孔嵌合硬質突出部加以焊銅(brazing)之方法或熱嵌法。 For the surface processing tools used for drill bits or masonry, most of the steel substrates are hard (usually super hard protrusions). The mounting method of the hard protruding portion is most generally a method in which a mounting hole for fitting a hard protruding portion is fitted to a substrate, and a hard protruding portion is fitted to the mounting hole to perform brazing or a heat embedding method.
然而，以上述焊銅法或熱嵌固定硬質突出部之工具在加工對象物為高溫時，工具本身會加熱成高溫，因此具有硬質突出部因熱應力而損傷並且脫落之問題。例如，熔爐之流出孔在已熔解之生鐵之流出結束時會再度閉塞，進行到下一熔解作業，但以鑽頭進行該流出孔之開口、或閉塞時之開口部的平坦化(為了使閉塞用之泥槍之前端部與流出孔開口周緣部緊密貼著，必須進行平坦化)時，由於爐壁溫度高，因此使用已將硬質突出部焊銅之鑽頭或已進行熱嵌之鑽頭時，具有超硬突出部會立刻脫落之問題點。 However, when the tool to be hardened by the above-described copper-welding method or heat-insertion is high in temperature, the tool itself is heated to a high temperature, so that the hard protrusion is damaged by the thermal stress and falls off. For example, the outflow hole of the furnace is closed again when the outflow of the molten pig iron is completed, and the next melting operation is performed. However, the opening of the outflow hole or the opening of the opening when the hole is closed by the drill bit (for the purpose of blocking) When the front end of the mud gun is in close contact with the peripheral edge portion of the opening of the outflow hole and must be flattened, since the temperature of the furnace wall is high, when the drill having the hard protruding portion is used to weld the copper or the drill having the hot insertion is used, The problem that the super-hard protrusion will fall off immediately.
挖掘工具中，突出部難以脫落之固定方法已知的有如 專利文獻1所揭示之方法。該方法係於突出部之基端部之側面形成凹凸形狀，並進行熔接以覆蓋該側面之方法。 In the excavation tool, the fixing method in which the protruding portion is difficult to fall off is known as The method disclosed in Patent Document 1. This method is a method in which a concave-convex shape is formed on a side surface of a base end portion of a protruding portion, and fusion is performed to cover the side surface.
【專利文獻1】日本專利公開公報特開第2003-214080號公報 [Patent Document 1] Japanese Patent Laid-Open Publication No. 2003-214080
上述專利文獻1所記載之方法係直接進行熔接以覆蓋突出部之外周面者，因此認為突出部應該可強固地保持，但若是材質較脆之超硬突出部時，則恐有因熱衝撃等影響而產生裂縫之虞，而有實用上的問題。該方法以外也想幾個方法，但目前尚未確立可耐於高溫下使用之超硬突出部等實用的固定方法。因此本發明之課題在於提供一種即使在高溫下使用時，也可強固地保持超硬突出部等之硬質突出部，難以產生脫落等固定方法。 The method described in the above Patent Document 1 is directly welded to cover the outer peripheral surface of the protruding portion. Therefore, it is considered that the protruding portion should be strongly held. However, in the case of a super-hard protruding portion having a brittle material, there is a fear of heat rushing or the like. The impact is caused by cracks, but there are practical problems. There are several methods other than this method, but a practical fixing method such as a super-hard protrusion that can be used at a high temperature has not yet been established. Therefore, an object of the present invention is to provide a fixing method capable of strongly holding a hard protruding portion such as a super-hard protruding portion even when used at a high temperature, and it is difficult to cause peeling or the like.
本發明為解決上述課題，提供如下之固定方法。即，第1項所記載之超硬工具之特徵在於：於設置於鋼製底材且具有母螺紋之安裝孔嵌入硬質突出部，並由其上螺固壓環以將前述硬質突出部推壓固定，且前述壓環係於外周部具有可與前述母螺紋螺合之公螺紋者。又，第2項所記載之硬質突出部之固定方法之特徵在於：於鋼製底材之適當處設置直徑比硬質突出部之外徑大之安裝孔，且於該安裝孔之內周部形成母螺紋，將具有前端部之徑較小且基部側之徑 逐漸變大之傾斜外周面的硬質突出部嵌入前述安裝孔，並且將外周部形成有可螺合於前述安裝孔之母螺紋的公螺紋、內周部形成有可緊密貼著於前述硬質突出部之外周之通孔的壓環，在前述硬質突出部插通到該通孔之狀態下，螺合於前述安裝孔之母螺紋，以壓住硬質突出部，藉此以將硬質突出部固定於底材之螺孔內部。該固定方法中，係如第3項所記載，宜將前述壓環之內面形成為下側較寬上側較窄之傾斜面，以緊密貼著於硬質突出部之外周面前述壓環之內面。又，第4項所記載之硬質突出部之固定方法之特徵在於：於鋼製底材之適當處設置直徑比硬質突出部之外徑大之安裝孔，並於該安裝孔之內周部形成母螺紋，且將底部一體形成有朝外周方向伸出之凸緣之硬質突出部嵌入前述安裝孔；並且將外周部形成有可螺合於前述安裝孔之母螺紋之公螺紋的壓環在前述硬質突出部插通其通孔之狀態下，螺合於前述安裝孔之母螺紋，以壓住硬質突出部之凸緣，藉此將硬質突出部固定於底材之螺孔內部。 In order to solve the above problems, the present invention provides the following fixing method. In other words, the superhard tool according to the first aspect is characterized in that the mounting hole provided in the steel substrate and having the female screw is fitted into the hard protruding portion, and the hard protruding ring is screwed thereon to press the hard protruding portion. The pressure ring is fixed to the outer peripheral portion and has a male thread that can be screwed with the female thread. Further, the method of fixing the hard protruding portion according to the second aspect is characterized in that a mounting hole having a diameter larger than an outer diameter of the hard protruding portion is provided at a suitable portion of the steel substrate, and is formed in an inner peripheral portion of the mounting hole. Female thread, which will have a smaller diameter at the front end and a diameter on the base side a hard protruding portion of the inclined outer peripheral surface is inserted into the mounting hole, and a male thread that can be screwed to the female thread of the mounting hole is formed in the outer peripheral portion, and an inner peripheral portion is formed to be in close contact with the hard protruding portion a pressure ring of the through hole of the outer circumference is screwed to the female thread of the mounting hole in a state in which the hard protruding portion is inserted into the through hole to press the hard protruding portion, thereby fixing the hard protruding portion to The inside of the screw hole of the substrate. In the fixing method, as described in the third aspect, it is preferable that the inner surface of the pressure ring is formed as an inclined surface having a narrower upper side on the lower side so as to be in close contact with the outer circumferential surface of the hard protruding portion. surface. Further, the method of fixing the hard protruding portion according to the fourth aspect is characterized in that a mounting hole having a diameter larger than an outer diameter of the hard protruding portion is provided at a suitable portion of the steel substrate, and is formed in an inner peripheral portion of the mounting hole. a female thread, and a hard protruding portion integrally formed with a flange projecting outward in the outer peripheral direction is fitted into the mounting hole; and a pressing ring having a male thread which can be screwed to the female thread of the mounting hole is formed in the outer peripheral portion. The hard protruding portion is inserted into the through hole, and is screwed to the female thread of the mounting hole to press the flange of the hard protruding portion, thereby fixing the hard protruding portion to the inside of the screw hole of the substrate.
本發明之超硬工具係以附有螺紋之壓環將硬質突出部以機械方式按壓固定於安裝孔之內部，因此可在熔爐之流出孔開口等高溫狀態下使用。又，根據本發明之硬質突出部之固定法，在硬質突出部嵌合於設於底材之安裝孔之狀態下，從其上方藉由壓環予以壓住，而且該壓環螺合且固著於安裝孔之內周部之母螺紋，因此硬質突出部可強固予以保持。該固定方法中，為了固定而不將硬質突出部加熱 到高溫，因此硬質突出部不產生裂縫等。又，由於不使用焊料，亦與使用熱膨脹之熱嵌不同，因此即使在使用時曝露於高溫也不用擔心突出部脫落。 In the superhard tool of the present invention, the hard protruding portion is mechanically pressed and fixed to the inside of the mounting hole by a threaded pressing ring, so that it can be used in a high temperature state such as an outlet opening of the furnace. Further, according to the fixing method of the hard protruding portion of the present invention, the hard protruding portion is fitted to the mounting hole provided in the substrate, and is pressed by the pressing ring from above, and the pressing ring is screwed and solidified. The female thread is placed on the inner circumference of the mounting hole, so that the hard protrusion can be firmly held. In the fixing method, the hard protrusion is not heated for fixing At a high temperature, cracks or the like are not generated in the hard projections. Further, since the solder is not used, it is different from the thermal expansion using thermal expansion. Therefore, even if it is exposed to a high temperature during use, there is no fear that the protruding portion will fall off.

以下，具體的說明本發明之實施形態。第1圖係例示本發明之超硬工具，硬質突出部3(此時為超硬突出部)之基部嵌合於設置於鋼製之底材1之頭部的安裝孔2。突出部3之底面與安裝孔2之底面7緊密貼著。 Hereinafter, embodiments of the present invention will be specifically described. Fig. 1 is a view showing a superhard tool of the present invention, in which a base portion of a hard protruding portion 3 (in this case, a super-hard protruding portion) is fitted to a mounting hole 2 provided in a head portion of a steel substrate 1. The bottom surface of the protruding portion 3 is in close contact with the bottom surface 7 of the mounting hole 2.
硬質突出部3係如第2圖所示，由頭部3a、主體部3b、 及基部3c所構成，且形成為頭部3a之前端部的徑較小，主體部側之徑較大概略砲彈型。主體部3b係徑均一之圓柱狀，基部3c係形成主體部側之徑較小、基部側之徑漸漸變大之截面圓錐狀之傾斜面。 As shown in Fig. 2, the hard protruding portion 3 is composed of a head portion 3a and a main body portion 3b. The base portion 3c is configured to have a smaller diameter at the front end portion of the head portion 3a and a larger diameter of the main body portion side. The main body portion 3b has a cylindrical shape having a uniform diameter, and the base portion 3c is formed as a sloped surface having a small diameter on the main body portion side and a tapered portion having a large diameter on the base portion side.
底材1之安裝孔2之內徑比硬質突出部3之基部之最大部之外徑大，在安裝孔內壁面與突出部外周面之間保有適度的間隙4。安裝孔2之內周部形成有母螺紋2a。 The inner diameter of the mounting hole 2 of the substrate 1 is larger than the outer diameter of the largest portion of the base portion of the hard protruding portion 3, and an appropriate gap 4 is maintained between the inner wall surface of the mounting hole and the outer peripheral surface of the protruding portion. A female thread 2a is formed in the inner peripheral portion of the mounting hole 2.
壓環5於中央部形成有硬質突出部3之上下中間部可嵌合之嵌合孔6。該嵌合孔6之內周面形成上窄下寬之喇叭狀之傾斜面，而可與突出部3之基部3c之傾斜外周面緊密貼著。又，壓環5之外周部形成有供安裝孔2之母螺紋2a螺合之公螺紋5a。再者，壓環5係螺合於底材之安裝孔2之母螺紋者，因此於其上部宜先設置扳手等工具之平扳鉗、卡合用銷孔等之卡合手段。 The pressure ring 5 is formed with a fitting hole 6 into which the lower middle portion of the hard protruding portion 3 can be fitted at the center portion. The inner peripheral surface of the fitting hole 6 is formed into a trumpet-like inclined surface having a narrow width and a wide width, and is in close contact with the inclined outer peripheral surface of the base portion 3c of the protruding portion 3. Further, a male screw 5a for screwing the female screw 2a of the mounting hole 2 is formed in the outer peripheral portion of the pressure ring 5. Further, since the pressure ring 5 is screwed to the female thread of the mounting hole 2 of the substrate, it is preferable to first provide a locking means such as a flat wrench of a wrench or the like, and a pin hole for engagement.
於該底材1固定硬質突出部3時，首先，將硬質突出部3嵌入安裝孔2之中央部，並由其上被覆壓環5，使硬質突出部3嵌合於嵌合孔6。 When the hard protruding portion 3 is fixed to the substrate 1, first, the hard protruding portion 3 is fitted into the central portion of the mounting hole 2, and the pressing ring 5 is covered thereon to fit the rigid protruding portion 3 to the fitting hole 6.
在此狀態下，壓環5螺合於安裝孔2之母螺紋，直到緊密貼著於硬質突出部3。圖示例中，壓環5之嵌合孔6之內周面係形成為與硬質突出部3之基部之傾斜面緊密貼著之傾斜面，因此內周面與硬質突出部之外周面緊密貼著之壓環5不會到達安裝孔2之底面7，而於該底面與壓板5之下面之間形成空間部。因此，突出部3被壓板5推壓而固定。特別是第6圖、第7圖之圖示例中，突出部3之外周面形成圓錐狀之 傾斜面，壓板5之內周面形成適合突出部之外周面之喇叭狀傾斜面，因此壓板5之嵌合孔內周面與突出部外周面緊密貼著，可強固地固定突出部。 In this state, the pressure ring 5 is screwed to the female thread of the mounting hole 2 until it is in close contact with the hard projection 3. In the example of the drawing, the inner peripheral surface of the fitting hole 6 of the pressure ring 5 is formed as an inclined surface which is in close contact with the inclined surface of the base portion of the hard protruding portion 3, so that the inner peripheral surface is closely attached to the outer peripheral surface of the hard protruding portion. The pressure ring 5 does not reach the bottom surface 7 of the mounting hole 2, and a space portion is formed between the bottom surface and the lower surface of the pressure plate 5. Therefore, the protruding portion 3 is pressed and fixed by the pressing plate 5. In particular, in the examples of the figures of Fig. 6 and Fig. 7, the outer peripheral surface of the protruding portion 3 is formed into a conical shape. In the inclined surface, the inner circumferential surface of the pressure plate 5 is formed with a flared inclined surface suitable for the outer circumferential surface of the protruding portion. Therefore, the inner circumferential surface of the fitting hole of the pressure plate 5 is in close contact with the outer circumferential surface of the protruding portion, and the protruding portion can be strongly fixed.
第3圖至第5圖係顯示底材1，該底材1係由鋼材製作，包含4個切削翼1a之上面(前端面)設有複數安裝孔2與嵌平孔8，於側面亦設有嵌平孔9。圖中之20為用以安裝於鑽頭之螺孔。第6圖係表示顯示出於硬質突出部3固著於上述底材1之完成狀態之鑽頭的外觀。 3 to 5 show a substrate 1 which is made of steel and includes a plurality of mounting holes 2 and flat holes 8 on the upper surface (front end surface) of the four cutting wings 1a, and is also provided on the side. There is a flat hole 9. 20 in the figure is a screw hole for mounting to a drill. Fig. 6 is a view showing the appearance of a drill which shows the state in which the rigid projection 3 is fixed to the above-mentioned substrate 1.
圖示例中，固定有硬質突出部3之壓環5之上面由底材1之表面稍微突出，但亦可設置成與底材1之表面大略在同一面。使用於流出孔之開口之鑽頭使用1次後會因為開口時之高熱而損傷硬質突出部，因此，大部分的情況是使用即丟。因此，硬質突出部之固定方法只要是可強固地固定成堪使用之程度者，外觀等不會成為問題。 In the illustrated example, the upper surface of the pressure ring 5 to which the hard projection 3 is fixed is slightly protruded from the surface of the substrate 1, but may be disposed to be substantially flush with the surface of the substrate 1. When the drill used for the opening of the outflow hole is used once, the hard protrusion is damaged by the high heat at the time of opening, and therefore, most of the cases are used. Therefore, the fixing method of the rigid protruding portion does not become a problem as long as it can be firmly fixed to a degree that can be used.
其次，第7、8圖係表示與上述有些許不同之實施形態者，在該實施形態中，凸緣31一體形成於硬質突出部3之基部。該凸緣31之外徑與安裝孔2之內徑大略相同，高度為數公厘，其上螺固有壓環5，壓環5之下面緊密貼著於前述凸緣31之上面。如此，與硬質突出部3成一體之凸緣31被壓環5壓住，因此硬質突出部3之固定更確實。 Next, the seventh and eighth drawings show a slightly different embodiment from the above, and in this embodiment, the flange 31 is integrally formed at the base of the hard protruding portion 3. The outer diameter of the flange 31 is substantially the same as the inner diameter of the mounting hole 2, and the height is several centimeters. The upper inner ring 5 and the lower surface of the pressure ring 5 are closely attached to the upper surface of the flange 31. Thus, the flange 31 integral with the hard protruding portion 3 is pressed by the pressing ring 5, so that the fixing of the hard protruding portion 3 is more sure.
其次，第9、10圖係顯示與上述若干不同之參考例，該參考例中，硬質突出部13之基部外周部直接設有公螺紋14。將該硬質突出部13直接螺合於母螺紋之經切割之安裝孔2。即，將硬質突出部13直接螺固於底材1。一般係將零 件螺固於基材，但由於硬質突出部一般來說較脆，不進行使用螺絲之固定。然而，使用於流出孔之開口之工具使用1次多半就要丟棄，因此可採用此種螺絲式的固定方法。如此，硬質突出部本身亦可形成公螺紋，由於一般較難在此種硬質突出部形成螺絲部，因此如上述實施形態所示，以壓環5按壓較為實用。 Next, the ninth and tenth drawings show a reference example different from the above, in which the outer peripheral portion of the base portion of the hard protruding portion 13 is directly provided with the male thread 14. The hard protrusion 13 is directly screwed to the cut mounting hole 2 of the female thread. That is, the hard protruding portion 13 is directly screwed to the substrate 1. General will be zero The piece is screwed to the substrate, but since the hard protrusion is generally brittle, it is not fixed by screws. However, the tool used for the opening of the outflow hole is discarded more than once, so that the screw type fixing method can be employed. As described above, the hard protruding portion itself can form a male screw. Since it is generally difficult to form the screw portion in such a hard protruding portion, it is practical to press the pressing ring 5 as shown in the above embodiment.
如以上所說明，根據本發明之硬質突出部固定方法，可以機械式將超硬突出部等之硬質突出部強固地固定於鋼製之底材，即使係對高溫之對象物使用時，亦成為突出部難以脫落者。又，在固定時，由於不會對突出部本身造成熱衝撃，因此即使係較脆材質之超硬突出部亦可確實地固定。 As described above, according to the method for fixing the rigid protruding portion of the present invention, the hard protruding portion such as the super-hard protruding portion can be mechanically fixed to the steel substrate, and even when used for a high-temperature object, The protrusion is difficult to fall off. Moreover, since the hot stamping of the protruding portion itself is not caused at the time of fixing, even the super-hard protruding portion of the brittle material can be surely fixed.
本發明之超硬工具中之硬質突出部之固定方法可不需強硬而可強固地將硬質突出部固定於鋼製之底材，可使用作為用於接受高熱之用途之超硬工具之突出部固定法。 The fixing method of the hard protruding portion in the superhard tool of the present invention can firmly fix the hard protruding portion to the steel substrate without being tough, and can be fixed by using a protruding portion as a superhard tool for receiving high heat. law.
