【０００１】0001
この考案は、金属板を溶断、切断あるいは錐孔加工した場合などに生ずるばり あるいはかえりを除去するように構成したワイドベルトサンダーにおいて研削ベ ルトの前段に用いられるばり取り用回転切削工具に関する。 This idea eliminates burrs that occur when cutting, cutting, or drilling metal plates. Alternatively, use a wide belt sander configured to remove burrs. This invention relates to a rotary cutting tool for deburring used in the front stage of a rotor.
【０００２】0002
従来のばり取り用のワイドベルトサンダーにおいて、研削ベルトの寿命を長も ちさせるために、その前段に回転切削工具を配置した構成のものがある。その回 転切削工具には、平面フライスが用いられている。 Extends the life of the grinding belt in conventional wide belt sanders for deburring. In order to increase the speed, there is a structure in which a rotary cutting tool is placed in front of the cutting tool. that time A plane milling cutter is used as a rolling cutting tool.
【０００３】 ばり取り用のワイドベルトサンダーは、ばり取りされる金属板がその板面に沿 う方向に所定の移送経路を送られる間に先ず平面フライスでばりの大部分を削り 落とし、次に研削ベルトで残りのばりを除去するようになっている。使用されて いる平面フライスは、刃のねじり方向が逆の一対のねじりフライスであり、これ を前後に接近させて配置してある。ねじりフライスは、この種のばり取り切削に おける切削状況はかなり良好ではあるが、ワークである金属板を移送しながら切 削することになるからそのワークの支持状態が必ずしも強力でなく、１個のねじ りフライスでは切削力の軸方向分力が生じてワークが所定の移送経路から横方向 に移動して片寄る不具合があり、さらにばりの性質上切削方向によってはうまく 削り落とせない問題もあり、これらの理由から反対方向の軸方向分力を生じるよ うにねじり方向が逆のもう１個のねじりフライスと組み合わせて使用することが 行われていた。なお、この種のばり取りにおいてはばり取りの際に、ワークであ る金属板の面に傷を付けないようにすること、あるいは金属板面に刻印されたロ ット番号やパーツ番号、罫書き線などが消えないようにすることも要求される。0003 A wide belt sander for deburring allows the metal plate to be deburred to run along the surface of the plate. Most of the burrs are first cut off with a plane mill while being sent along a predetermined transfer path in the direction of The remaining burrs are then removed using a grinding belt. used The plane milling cutter is a pair of twist milling cutters whose blades have opposite twisting directions; are placed close together in the front and back. Torsion milling is suitable for this type of deburring cutting. Although the cutting conditions are quite good, Since the workpiece will be cut, the support state of the workpiece is not necessarily strong, and one screw In edge milling, an axial component of the cutting force is generated, causing the workpiece to move laterally from the predetermined transport path. There is a problem where the burr moves to one side and becomes uneven, and due to the nature of the burr, it may not work properly depending on the cutting direction. There are some problems that cannot be removed, and for these reasons, it is necessary to Can be used in combination with another twist milling cutter with the opposite twist direction. It was done. In addition, in this type of deburring, when deburring, the workpiece Be careful not to scratch the surface of the metal plate, or remove any marks engraved on the metal plate. It is also required to ensure that cut numbers, part numbers, marking lines, etc. do not disappear.
【０００４】0004
従来のねじり方向が逆の一対のねじりフライスを使用するワイドベルトサンダ ーは、２個のフライスを各別に支持して回転駆動する２個の工具ヘッドが必要で あるから、ばり取り用ベルトサンダーが大型になるという問題があり、また当然 ２種類の工具が必要であるから、工具の種類が増える点にも問題があった。 A wide belt sander that uses a pair of conventional torsion milling cutters with opposite twist directions. - requires two tool heads that separately support and rotate two milling cutters. Therefore, there is a problem that the belt sander for deburring becomes large, and of course Since two types of tools are required, there is also a problem in that the number of types of tools increases.
【０００５】 この考案は、前記問題点を解決することを目的とし、１個の回転工具で、ばり 取り時にワークが移送方向に対して横方向に移動しないように、研削ベルとの前 段用としてばりを除去できるようにすることを技術的課題とする。[0005] The purpose of this invention is to solve the above-mentioned problems. In order to prevent the workpiece from moving laterally to the transport direction during picking, The technical challenge is to be able to remove burrs for use in stages.
【０００６】[0006]
この考案の手段は、円柱状本体周面に同一リードで右巻きと左巻きの溝を形成 することにより菱形の小凸部を多数形成し、上記本体を支持して本体の中心軸回 りに回転駆動可能に本体に軸部又は軸結合部を設けてなることを特徴とする。 The method of this invention is to form right-handed and left-handed grooves with the same lead on the circumferential surface of the cylindrical body. By doing so, a large number of small diamond-shaped convex portions are formed, supporting the main body and rotating the central axis of the main body. The main body is provided with a shaft portion or a shaft coupling portion so as to be rotatably driven.
【０００７】[0007]
この回転工具は、本体周面に溝の縁で形成される角部の回転方向前側のものが 刃先である。本体を中心軸回りに回転させると菱形の小凸部がそれぞれに同様に 所定の対角線の方向に回転するから、ワイドベルトサンダーに設けて金属板のば り取りに使用すると、菱形の小凸部による切削力もしくは衝撃力は、菱形の回転 方向前側の２辺にそれぞれ垂直な斜め前向きに作用するものであるから、回転方 向に沿った前方向分力と互いに反対向きの本体中心軸に平行な横方向分力とに分 けて考えることができ、個々の小凸部についてみると反対向きの横方向分力が均 等でない場合もあり得るが殆どの場合均等であるから、多数の小凸部では左右で 相殺されてしまい、前方向分力のみが金属板に作用している状態となる。 This rotary tool has a corner formed by the edge of a groove on the circumference of the main body, which is located at the front in the direction of rotation. It is the cutting edge. When the main body is rotated around the central axis, the small diamond-shaped protrusions will appear in the same way. Since it rotates in a predetermined diagonal direction, it can be installed on a wide belt sander to easily cut metal sheets. When used for cutting, the cutting force or impact force due to the small protrusions of the rhombus is caused by the rotation of the rhombus. Since it acts diagonally forward and perpendicular to the two front sides, the direction of rotation The force is divided into a forward component along the direction and a lateral component parallel to the center axis of the body, which is opposite to each other. When looking at each small convex part, the opposite lateral components of force are equalized. There may be cases where it is not equal, but in most cases it is equal, so in many small convex parts, the left and right sides are equal. They cancel each other out, leaving only the forward component force acting on the metal plate.
【０００８】 従って、金属板は１個の回転工具から切削力もしくは衝撃力を受けるのである が、いくつかの小凸部が一枚の金属板に作用することになるから、横方向分力が 互いに相殺されてワイドベルトサンダーの所定の移送経路内で横方向へ移動する ことはない。[0008] Therefore, the metal plate receives cutting force or impact force from one rotating tool. However, since several small convex parts act on one metal plate, the lateral component of force is They cancel each other out and move laterally within the predetermined transport path of the wide belt sander. Never.

この考案の１実施例を図１および図２を用いて説明する。図において、１は回 転工具全体を示し、２は本体、３は軸部である。本体２は例えば工具鋼で形成し たもので最終的には熱処理により刃部の硬度を上げて、研磨仕上げしてある。そ の形状及び大きさは、所定のワイドベルトサンダーの幅に対応する長さ８５０ｍ ｍ、そして外径７０ｍｍの円柱状体の外周面に、左巻きの溝４と右巻きの溝５と を設けて、多数の菱形の小凸部６を形成したものである。溝４、５は、左右の巻 き方向が異なるが、いずれも４条で、リードが１００ｍｍであり、溝に直角な溝 断面形状も図２に示すような同じものである。同図における溝開口幅ａは１０ｍ ｍ、溝両側面のなす角度θは３０°（片側が１５°）、溝深さｄは８ｍｍ、溝底 幅ｂは約６ｍｍである。 One embodiment of this invention will be described using FIGS. 1 and 2. In the figure, 1 is The entire rolling tool is shown, and 2 is the main body and 3 is the shaft. The body 2 is made of tool steel, for example. Finally, the hardness of the blade is increased by heat treatment and polished. So The shape and size of is 850 m long, which corresponds to the width of the specified wide belt sander. m, and a left-handed groove 4 and a right-handed groove 5 are formed on the outer peripheral surface of a cylindrical body with an outer diameter of 70 mm. , and a large number of small diamond-shaped protrusions 6 are formed. Grooves 4 and 5 are for left and right windings. Although the directions are different, both have 4 threads, the lead is 100 mm, and the groove is perpendicular to the groove. The cross-sectional shape is also the same as shown in FIG. The groove opening width a in the same figure is 10 m. m, the angle θ between both sides of the groove is 30° (15° on one side), the groove depth d is 8mm, the groove bottom The width b is approximately 6 mm.
【００１０】 この回転工具１は、ワイドベルトサンダーの研削ベルトの前段に、金属板の表 面から０．５ｍｍ離れた位置で周面が回転するように設置し、回転数４００ｒ． ｐ．ｍ．で使用し、研削ベルトによるばり取り研削の前段階のばり取り加工を良 好に行うことが出来た。すなわち、溶断して切り口に厚さ方向に１ｍｍ前後突出 したばりを有する金属板を供給して、そのばりをほとんど根元に近い位置から除 去することができ、そして金属板の表面に傷は認められなかった。研削ベルトの 前段のばり取りは突出量の大きいばりが確実に除去されることが必要であるが、 これは十分に満足できる結果であった。そして金属板が所定の移送経路から横方 向に移動するようなことは殆どなかった。なお、この工具によるばりの除去は切 削と言うよりは衝撃による折り取りに近いようである。0010 This rotary tool 1 is equipped with a metal plate on the front stage of the grinding belt of a wide belt sander. It was installed so that the peripheral surface rotated at a position 0.5 mm away from the surface, and the rotation speed was 400 r. p. m. It is used to improve deburring processing before deburring and grinding using a grinding belt. I was able to do it well. In other words, it is fused and protrudes around 1mm in the thickness direction at the cut end. A metal plate with a thick burr is supplied, and the burr is removed almost from the position close to the root. No scratches were observed on the surface of the metal plate. grinding belt When removing burrs in the first stage, it is necessary to ensure that large protruding burrs are removed. This was a fully satisfactory result. Then, the metal plate is moved laterally from the predetermined transfer path. There was almost no movement in that direction. Note that this tool cannot be used to remove burrs. It seems more like a break-off caused by an impact than a cut.
【００１１】 上記実施例において、工具本体２と軸部３とは一体に形成したものを図示説明 したが、場合によっては別個に形成してもよく、要は本体の中心軸の回りに回転 駆動できるようになっていればよい。[0011] In the above embodiment, the tool body 2 and the shaft portion 3 are integrally formed. However, depending on the case, it may be formed separately, in short, it can be formed by rotating around the central axis of the main body. It is sufficient if it can be driven.
【００１２】 上記実施例において、溝の断面形状を溝の開放側へ３０°開いたものを示した が、この角度θは０°〜３０°の範囲で変更してもよい。0012 In the above example, the cross-sectional shape of the groove is shown as opening 30 degrees toward the open side of the groove. However, this angle θ may be changed within the range of 0° to 30°.
【００１３】[0013]
以上のようにこの考案によれば、回転工具のばり取り作用する小凸部の形状か ら、切削力もしくはばり取り作用力の横方向分力が左右で相殺されて殆ど作用し ないから、ワイドベルトサンダーの研削ベルトの前段において、１個の回転工具 でばり取りをしてもワークが移送路上で片寄ることがない。従ってこの回転工具 をワイドベルトサンダーに用いるときは回転工具の装着ヘッドを従来の２個から １個に減らすことができる。これによってワイドベルトサンダーの大きさを従来 よりも小さくできる。 As described above, according to this invention, the shape of the small convex part that acts on the rotating tool to remove burrs Therefore, the lateral component of the cutting force or deburring force is canceled out on the left and right, and almost no force acts. Because there is no one rotary tool in the front stage of the wide belt sander's grinding belt. Even when deburring is performed, the workpiece does not shift to one side on the transfer path. Therefore this rotary tool When using a wide belt sander, the mounting head of the rotary tool can be changed from the conventional two. It can be reduced to one. This reduces the size of wide belt sanders to conventional It can be made smaller than.
