Description
本考案は再利用できる一種のPCBドリル・ルーターの接合型柄の再生構造であり、特に、刀柄は刃具と直接に接合でき、刃具を外した後に再利用できるものを指している。これにより、材料コスト、研磨材料の損傷と消耗、加工プロセスを減少し、競争力を高めることができる上に、環境保護の利点をも持っている。 The present invention is a kind of reusable PCB drill / router joint type remanufactured structure. In particular, the sword pattern refers to the one that can be directly joined to the cutting tool and reused after the cutting tool is removed. This reduces material costs, damage and wear of abrasive materials, processing processes, increases competitiveness, and also has environmental protection benefits.
接合型PCBの切削刃具は高硬度の超硬合金製の刃先部位とステンレス棒材の刀柄との接合で構成されている。その刃具はPCB基板で切断と穴あけの作業を行った後、刃先部位が損傷や断裂になる。PCBルーターの刃先部位に破損がある場合、刃具を廃棄するのは一般的である。 The cutting tool of the joining type PCB is configured by joining a cutting edge part made of a hard metal cemented carbide and a sword handle of a stainless steel bar. After cutting and drilling the blade with a PCB substrate, the cutting edge becomes damaged or ruptured. It is common to discard the blade if the blade edge of the PCB router is damaged.
図１と図２は、周知の接合型PCB切削刃具の構造を示している。それは主に、超硬合金製の刃先部位9とステンレス棒材の刀柄8との接合で構成されている。当構造の刃先部位9の長さはL1、且つ超微粒(0.6um以下)レベルの超硬合金材料が使用されている。また、刃先部位9の直径D2はほぼ刀柄8の直径D1(図１のように)と等しくて、その直径D1とD2は周知の3.175mmである。 1 and 2 show the structure of a well-known bonded type PCB cutting blade. It is mainly constituted by joining a cutting edge portion 9 made of cemented carbide and a sword handle 8 made of stainless steel bar. The length of the cutting edge portion 9 of this structure is L1, and a cemented carbide material of an ultrafine particle (0.6 um or less) level is used. Further, the diameter D2 of the cutting edge portion 9 is substantially equal to the diameter D1 (as shown in FIG. 1) of the sword handle 8, and the diameters D1 and D2 are well-known 3.175 mm.
前述の刃先部位9の接合部は刀柄8接合部と溶接で連結され、且つ刃先部位9は研磨加工によって研磨部91が除去されているため、直径D4の刃先92及び刃先92が片端へ延伸する前刃錐部93は形成されている。 Since the joint portion of the blade tip portion 9 is connected to the sword handle 8 joint portion by welding, and the blade portion 9 has the polishing portion 91 removed by polishing, the blade edge 92 and the blade edge 92 having a diameter D4 extend to one end. The front edge cone portion 93 is formed.
前述の接合型PCBルーター構造では、ステンレス棒材の刀柄8と刃先部位9の高温溶接作業が行われた場合、ステンレス棒材の刀柄8は高温で変形量が多くなるため、刀柄8の寸法(前述の通りに直径D1は3.175mm)を大きめにする必要がある。それに対し、業者も刀柄8と接合できるように、刀柄8との接合部にある刃先部位9の寸法(前述の通りに直径D2は3.175mm)を合わせて大きくする必要がある。しかし、刃先部位9の寸法を大きくした後、直径がD4(現にあるPCBドリルの主要寸法は約0.2〜0.5mm)になる刃先92、及び刃先92が片端へ延伸する前刃錐部93を形成させるように、研磨部91を研磨加工で除去しなければならない。これにより、刃先92の直径(D4)と刃先部位9(D2)の直径には6〜15倍の差があり、刃先92の体積及び重量と除去された研磨部91の間には更に数十倍の差があり、研磨の量は相当に大きいことが分かる。研磨の量が大きいため、加工プロセスが増えてしまう。超硬合金材料の価格は重量で計算されるため、研磨量の増加に伴い、刃先部位9の材料コストが増加する上、研磨加工によるダイヤモンド研削砥石の損傷と消耗率を高め、製造時間も増加する。 In the above-described bonded PCB router structure, when high-temperature welding work is performed on the stainless steel bar sword handle 8 and the cutting edge 9, the stainless steel bar sword pattern 8 is deformed at a high temperature, so the sword pattern 8 (As mentioned above, the diameter D1 is 3.175 mm). On the other hand, it is necessary to increase the size (the diameter D2 is 3.175 mm as described above) of the cutting edge portion 9 at the joint portion with the sword handle 8 so that the trader can also join the sword handle 8. However, after increasing the size of the cutting edge part 9, the cutting edge 92 whose diameter becomes D4 (the main dimension of the current PCB drill is about 0.2 to 0.5 mm) and the front cutting edge part 93 where the cutting edge 92 extends to one end are formed. Thus, the polishing portion 91 must be removed by polishing. As a result, there is a difference of 6 to 15 times in the diameter (D4) of the blade edge 92 and the diameter of the blade edge portion 9 (D2), and there are several tens of times between the volume and weight of the blade edge 92 and the removed polishing portion 91. It can be seen that there is a double difference and the amount of polishing is quite large. Since the amount of polishing is large, the processing process increases. Since the price of cemented carbide material is calculated by weight, the material cost of the cutting edge 9 increases as the polishing amount increases, and the damage and wear rate of the diamond grinding wheel is increased by polishing and the manufacturing time also increases. To do.
以上から分かるように、当該周知の接合型PCBルーター構造には欠点があり、改良が必要である。 As can be seen from the foregoing, the known bonded PCB router structure has drawbacks and needs improvement.
前述の従来技術の欠点を鑑み、本考案の目的は、接合技術に関する問題を解決し、材料コストの削減、研削砥石の損傷と消耗の低減ならびに、加工プロセスを削減すると共に、競争力を向上させ、環境保護のコンセプトにふさわしい再利用できるPCBドリル・ルーターの接合型柄の再生構造を提供することにある。 In view of the above-mentioned drawbacks of the prior art, the object of the present invention is to solve the problems related to joining technology, reduce material costs, reduce grinding wheel damage and wear, reduce machining processes and improve competitiveness. The purpose is to provide a reusable PCB drill / router joint-type recycling structure suitable for the concept of environmental protection.
以上の目的を実現するには、本考案は再利用できる一種のPCBドリル・ルーターの接合型柄の再生構造を提供している。それには超硬合金製の刃具と再利用できる超硬合金製の刀柄との接合で構成されている。当該刃具は研磨で刃先と刃先の片端から外部へ延伸する錐部を形成している。当該錐部の片端は刀柄に接続している。 In order to achieve the above objective, the present invention provides a reusable structure of a reusable PCB drill / router joint pattern. It consists of a cemented carbide blade and a reusable cemented sword handle. The cutting tool forms a conical portion extending outward from one end of the cutting edge and the cutting edge by polishing. One end of the cone is connected to the sword handle.
その中：前述の刀柄の片端は研磨で錐度を呈するネック部及びネック部の片端が外部へ延伸する刀柄を形成している。当該ネック部の片端は溶接で前述の刃具の錐部に接続されている。 Among them: One end of the above-mentioned sword pattern forms a neck part exhibiting a conical degree by polishing and a sword pattern in which one end of the neck part extends to the outside. One end of the neck part is connected to the cone part of the above-mentioned blade tool by welding.
前述の刃具は使用後に刀柄から取り除かれ、且つネック部は別の刃具と互いに接合することによって、刀柄の再利用を実現する。 The aforementioned blade tool is removed from the sword pattern after use, and the neck portion is joined to another blade tool to realize reuse of the sword pattern.
前述の技術手段により、本考案は従来の欠点を改良し、材料コスト、研磨材料の損傷と消耗、そして、加工プロセスを減少することができる上、競争力の向上と環境保護に利点をも持っている。 By the above technical means, the present invention can improve the conventional drawbacks, reduce the material cost, damage and wear of the abrasive material, reduce the processing process, and also have the advantages of competitiveness and environmental protection. ing.
図２と図３に示すように、当考案の再利用できるPCBドリル・ルーターの接合型柄の再生構造の好ましい実施例は、超硬合金製の刃具1及び再利用できる超硬合金製の刀柄2の接合による構造を含めている。 As shown in FIGS. 2 and 3, the preferred embodiment of the reusable PCB drill / router joint pattern recycling structure of the present invention is a cemented carbide blade 1 and a reusable cemented carbide sword. Includes structure with handle 2 joint.
前述の刃具1は研磨加工で形成された刃先11及び刃先11の片端が外部へ延伸する錐部12である。錐部12の片端は刀柄2に接続している。 The cutting tool 1 described above is a cutting edge 11 formed by polishing and a conical portion 12 at which one end of the cutting edge 11 extends outward. One end of the cone 12 is connected to the sword handle 2.
前述の刀柄2の片端は研磨加工で錐度を呈するネック部21、及びネック部21の片端が外部へ延伸する柄22を形成する。当該ネック部21の片端は溶接で刃具1の錐部12と接続し、互いに刃具1と刀柄2を接合させる。且つ、刀柄2は主に刃具を機械に取り付ける目的のみに必要な部分であるため、レベルの低い粗い顆粒(1um以上)の廉価な超硬合金材料を使用してコストを抑えることができる。 One end of the above-described sword pattern 2 forms a neck portion 21 that exhibits a conical degree by polishing and a handle 22 in which one end of the neck portion 21 extends outward. One end of the neck portion 21 is connected to the conical portion 12 of the blade 1 by welding, and the blade 1 and the sword handle 2 are joined to each other. In addition, since the sword handle 2 is a part necessary mainly for the purpose of attaching the cutting tool to the machine, it is possible to reduce the cost by using an inexpensive cemented carbide material having a low level of coarse granules (1 um or more).
前述の刃具1は使用後、刀柄2から外せるようになっており、ネック部21が新品の刃具1と接合することにより刀柄2の再利用が実現できる。 The blade 1 described above can be removed from the sword handle 2 after use, and the sword handle 2 can be reused by joining the neck portion 21 to the new blade 1.
刃具1と刀柄2の接合作業では、刀柄2が超硬合金材料となっているため、刀柄2が高温による変形量が比較的に少ない。そのため、周知の技術と比べると、刀柄2を小さくして刃具1と接合することができる。図１と図３のように、その中、本考案は超硬合金製の刃具1と再利用できる超硬合金製の刀柄2との接合で構成されるものである。当該超硬合金製の刃具1の長さL2が、周知の刃先部位9の長さL1と比べれば分かるようにL2はL1より短い。且つ、超硬合金製の刃具1の直径D3は二種類の応用仕様に分けられる。その一はドリル仕様であり、当該直径D3は1.5mmまたはそれ以下であり、ドリルの主要寸法の0.2〜0.5mmによる生産作業に役立たせる。その二はルーター仕様であり、当該直径D3は2.0mmまたはそれ以下であり、ルーターの主要寸法の1.2mm以下の生産作業に役立たせる。また、ドリル仕様、ルーター仕様にも関わらず、その直径D3は周知の刃先部位9の直径D2(3.175mm)に比べると、当該直径D3が明らかに直径D2より小さい。 In the joining operation of the blade 1 and the sword handle 2, since the sword handle 2 is made of a cemented carbide material, the amount of deformation of the sword handle 2 due to high temperature is relatively small. Therefore, compared with a well-known technique, the sword handle 2 can be made smaller and joined to the blade 1. As shown in FIGS. 1 and 3, the present invention is constituted by joining a cemented carbide blade 1 and a reusable cemented carbide handle 2. L2 is shorter than L1, as can be seen by comparing the length L2 of the cemented carbide cutting tool 1 with the known length L1 of the cutting edge portion 9. Moreover, the diameter D3 of the cutting tool 1 made of cemented carbide is divided into two types of application specifications. One of them is the drill specification, and the diameter D3 is 1.5 mm or less, which is useful for production work with the main dimensions of the drill of 0.2 to 0.5 mm. The second is a router specification, and the diameter D3 is 2.0 mm or less, which is useful for production work of 1.2 mm or less of the main dimensions of the router. Regardless of the drill specifications and the router specifications, the diameter D3 is clearly smaller than the diameter D2 compared to the diameter D2 (3.175 mm) of the well-known cutting edge 9.
また、周知の技術では刃先部位9の直径D2に対し、3.175mmから直径0.2〜0.5mmの刃先92に研磨するが、本考案の超硬合金製の刃具1の直径D3は、1.5mm(またはそれ以下)から直径が0.2mm〜0.5mmの刃先11になるまで研磨するようになっている。比べると、本考案は明らかに研磨量を抑えることができ、超硬合金材料の浪費を有効に抑止し、研磨加工のプロセスを減少することもでき、加工効率を向上させる。 Further, in the known technique, the diameter D2 of the cutting edge part 9 is polished to a cutting edge 92 having a diameter of 3.175 mm to 0.2 to 0.5 mm, but the diameter D3 of the cemented carbide cutting tool 1 of the present invention is 1.5 mm (or From this point, the polishing is performed until the cutting edge 11 has a diameter of 0.2 mm to 0.5 mm. In comparison, the present invention can obviously reduce the polishing amount, effectively suppress the waste of the cemented carbide material, reduce the polishing process, and improve the processing efficiency.
