Description

この発明は、溶接用充填材の余盛形状整形治具に関する。 The present invention relates to an extra shape shaping jig for a filler for welding.

鋼製橋梁の部材加工・施工において、鋼板同士の接合方法として溶接が用いられることが多い。その溶接方法の１つであるサブマージアーク溶接法では、細裁断した細径鋼素線や鉄粉などの鋼製の充填材を、２つの鋼板間に形成した溝である開先に充填することで溶着量を増加させ、作業効率・品質を向上させることがある。 Welding is often used as a method of joining steel plates in the processing and construction of steel bridge members. In the submerged arc welding method, which is one of the welding methods, a steel filler such as a fine-diameter steel wire or iron powder that has been shredded is filled in a groove formed between two steel plates. May increase the amount of welding and improve work efficiency and quality.

一般的には、充填材は人力作業で簡易な整形ができるように、鋼板表面と同一となるようにされている。具体的には、充填材を開先に充填した後、平板をその一辺が鋼板表面に接した状態で溶接線方向に沿って移動させて、余剰充填材を回収し、充填材の充填高さが鋼板表面と同一となるように整形している。 Generally, the filler is made to be the same as the surface of the steel plate so that it can be easily shaped by manual work. Specifically, after filling the groove with the filler, the flat plate is moved along the welding line direction with one side in contact with the surface of the steel plate to collect the surplus filler, and the filling height of the filler is obtained. Is shaped so that it is the same as the surface of the steel plate.

ところで、近年では、より品質・作業効率を向上させるために、充填材を鋼板表面よりも高く盛り上げて、すなわち余盛りをして整形するサブマージアーク溶接法が普及している。 By the way, in recent years, in order to further improve the quality and work efficiency, the submerged arc welding method in which the filler is raised higher than the surface of the steel plate, that is, the filler is formed by extra filling, has become widespread.

しかしながら、充填材の整形作業は一般的に人力作業となるため、余盛形状を溶接線方向に均一に整形することが困難であり、余盛形状にばらつきが生じる。図８及び図９は、余盛形状のばらつきを示し、図８は平面図、図９は図８のイ）、ロ）、ハ）線による断面図である。ロ）線による断面で示される部分は余盛が適性であるが、イ）、ハ）線による断面で示される各部分は、それぞれ余盛過剰及び余盛不足となっている。なお、図８及び図９において、符号２０は溶接される２つの鋼板、２１は開先、２２は充填材を示す。 However, since the shaping work of the filler is generally a manual work, it is difficult to uniformly shape the surplus shape in the direction of the welding line, and the surplus shape varies. 8 and 9 show variations in the surplus shape, FIG. 8 is a plan view, and FIG. 9 is a cross-sectional view taken along the lines a), b), and c) of FIG. B) The part shown by the cross section by the line is suitable for the surplus, but each part shown by the cross section by a) and c) the line is excessive and insufficient, respectively. In FIGS. 8 and 9, reference numeral 20 indicates two steel plates to be welded, 21 indicates a groove, and 22 indicates a filler.

上記のような、余盛形状のばらつきは、溶接後の外観不良や内部欠陥の発生といった溶接部の品質低下の要因となる。また、図８及び図９に符号２２ａで示すように、粉末性状である余剰充填材が整形範囲外に散乱するため、回収の作業範囲が大きくなり、作業時間の増加をもたらす。 The variation in the surplus shape as described above causes deterioration of the quality of the welded portion such as poor appearance after welding and occurrence of internal defects. Further, as shown by reference numeral 22a in FIGS. 8 and 9, since the excess filler in the powdery state is scattered outside the shaping range, the recovery work range is increased and the work time is increased.

この発明の先行技術文献として特許文献１を挙げることができる。しかしながら、同文献に記載の余盛整形治具は、溶接作業で用いる裏当金に相当するもので、本件発明のものとは相違する。 Patent Document 1 can be mentioned as the prior art document of the present invention. However, the surplus shaping jig described in the same document corresponds to the backing metal used in the welding work, and is different from that of the present invention.

この発明の実施形態を図面を参照しながら以下に説明する。図１～図３は、この発明による溶接用充填材の余盛形状整形治具の実施形態を示している。余盛形状整形治具１０は矩形の板状部１１を備えている。板状部１１は、整形治具１０の使用時に縦向きにされて、溶接される２つの金属板である鋼板２０、２０の表面に接した状態（図５参照）とされる下部辺１２を有している。 An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment of an extra shape shaping jig for a welding filler according to the present invention. The extra shape shaping jig 10 includes a rectangular plate-shaped portion 11. The plate-shaped portion 11 has a lower side 12 which is oriented vertically when the shaping jig 10 is used and is in contact with the surfaces of the two metal plates 20 and 20 to be welded (see FIG. 5). Have.

下部辺１２には、そのほぼ中央に矩形の切欠き１３が形成されている。この切欠き１３は、充填材の余盛形状に即した寸法を有している。具体的には、切欠き１３は鋼板２０、２０間に形成される開先２１（図５参照）の幅寸法とほぼ等しい長さ寸法を有し、また充填材の余盛高さとほぼ等しい高さ寸法を有している。 On the lower side 12, a rectangular notch 13 is formed substantially in the center thereof. The notch 13 has a dimension corresponding to the shape of the surplus of the filler. Specifically, the notch 13 has a length dimension substantially equal to the width dimension of the groove 21 (see FIG. 5) formed between the steel plates 20 and 20, and a height substantially equal to the surplus height of the filler. Has dimensions.

下部辺１２を挟む板状部１１の両側部には、整形治具１０の移動方向（図４に矢印Ｅで示す）前方に張り出す充填材の散乱抑止部１４、１４が設けられている。この散乱抑止部１４、１４は板状部１１に対してほぼ直角をなすように設けられている。 Scattering suppression portions 14 and 14 of the filler projecting forward in the moving direction of the shaping jig 10 (indicated by an arrow E in FIG. 4) are provided on both sides of the plate-shaped portion 11 sandwiching the lower side 12. The scattering suppression portions 14 and 14 are provided so as to form a substantially right angle to the plate-shaped portion 11.

整形治具１０は、腐食しにくいステンレス鋼を用いて作られるが、磁気による鋼製の充填材との吸着を防ぐため、磁界が発生しない材質例えば硬質プラスチックや木を用いることもできる。 The shaping jig 10 is made of stainless steel that does not easily corrode, but in order to prevent magnetic adsorption with the steel filler, a material that does not generate a magnetic field, such as hard plastic or wood, can also be used.

図４及び図５は整形治具１０を用いて、充填材の余盛形状を整形している状態を示している。整形作業に先立ち、充填材２２は鋼板２０、２０間の開先２１に充填され、さらにその上に所要の余盛高さ以上となるように供給されている。その後、以下のようにして、整形治具１０により余盛形状が整形される。 FIGS. 4 and 5 show a state in which the surplus shape of the filler is shaped by using the shaping jig 10. Prior to the shaping work, the filler 22 is filled in the groove 21 between the steel plates 20 and 20, and is further supplied on the filler 22 so as to have a required surplus height or more. After that, the surplus shape is shaped by the shaping jig 10 as follows.

すなわち、整形治具１０は、板状部１１の下部辺１２が鋼板２０、２０の表面に接し、かつ切欠き１３が開先２１を跨いだ状態で該開先２１と直交するするように、鋼板２０、２０の上に載置される。 That is, the shaping jig 10 is orthogonal to the groove 21 in a state where the lower side 12 of the plate-shaped portion 11 is in contact with the surfaces of the steel plates 20 and 20 and the notch 13 straddles the groove 21. It is placed on the steel plates 20 and 20.

そして、整形治具１０を鋼板２０、２０の一方の端から他方の端に向けて、図４の溶接線方向Ｄに沿うように矢印方向Ｅに移動させる。これにより、整形治具１０が通過した領域は、図６及び図７の断面で示すように、充填材２２が切欠き１３の形状に応じた余盛形状に均一に整形される。 Then, the shaping jig 10 is moved from one end of the steel plates 20 and 20 toward the other end in the arrow direction E along the welding line direction D in FIG. As a result, in the region where the shaping jig 10 has passed, as shown in the cross sections of FIGS. 6 and 7, the filler 22 is uniformly shaped into an extra shape corresponding to the shape of the notch 13.

一方、整形治具１０による整形時に余剰となった充填材２２ａは、板状部１１によって整形治具１０の移動方向前方に押しやられ、整形前充填材として回収される。このとき、余剰充填材２２ａは開先２１の両側方に流れようとするが、散乱抑止部１４、１４によって遮られて散乱するのが抑止される。なお、この散乱抑止部１４、１４は、整形治具１０の移動時に前方へ転倒するのを防止する機能も併せ持っている。 On the other hand, the filler 22a that becomes surplus during shaping by the shaping jig 10 is pushed forward by the plate-shaped portion 11 in the moving direction of the shaping jig 10 and is recovered as the pre-shaping filler. At this time, the excess filler 22a tries to flow to both sides of the groove 21, but is blocked by the scattering suppressing portions 14 and 14 to prevent scattering. The scattering suppression units 14 and 14 also have a function of preventing the shaping jig 10 from tipping forward when moving.

上記実施形態は例示にすぎず、この発明は種々の態様を採りうる。例えば、上記実施形態では板状部を矩形形状としたが、板状部は鋼板に接することができる下部辺を有していればよく、矩形形状に限らない。 The above embodiment is merely an example, and the present invention may take various embodiments. For example, in the above embodiment, the plate-shaped portion has a rectangular shape, but the plate-shaped portion may have a lower side that can be in contact with the steel plate, and is not limited to the rectangular shape.
