この発明は、溶接Ｈ形鋼等の溶接形鋼を製造す
る際に溶接部において溶接形鋼のウエブ材を支持
する溶接部支持装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a welded section support device that supports a web material of a welded section steel at a welded section when manufacturing a welded section steel such as a welded H section steel.
例えば、溶接Ｈ形鋼は、コイルから巻戻した３

すように、溶接部においては、上下圧接ロール
１，１の圧接力に伴うウエブ材Ｗの逃げを防止す
るためにウエブ材Ｗを拘束、支持する必要がある
が、従来設備においては全て円形ロール２で線支
持している。そのため、溶接開始点から溶接完了
点までの間の一点のみでしか支持できず、ウエ
ブ材Ｗの平坦不良、電極Ｅの押当力、溶接時
の圧接力、などによつて発生するウエブ材Ｗの逃
げを防止しきれず、フランジ材Ｆの加熱中心と溶
接中心とが一致しないことがあり、溶接不良を発
生しやすい。 For example, welded H-beams can be unwound from a coil by 3
It is manufactured continuously by assembling two plates into an H shape and welding them using high frequency resistance welding.As shown in Fig. 1, at the welding part, the web material is In order to prevent the web material W from escaping, it is necessary to restrain and support the web material W, but in conventional equipment, all of the web material W is linearly supported by circular rolls 2. Therefore, the web material W can only be supported at one point between the welding start point and the welding completion point, and the web material W can be supported by only one point between the welding start point and the welding completion point, and the web material W can be supported due to poor flatness of the web material W, the pushing force of the electrode E, the pressure contact force during welding, etc. The heating center of the flange material F and the welding center may not coincide with each other, and welding defects are likely to occur.
この溶接不良の防止策として、第２図に示すよ
うに、ウエブ支持ロール２を溶接部上流側に若干
ずらして配置して効果をあげているが、それでも
横方向に逃げようとする力を防ぎきらない場合が
あり特にウエブ材が薄い場合に多く、溶接不良が
発生しやすい。 As a measure to prevent this welding defect, as shown in Fig. 2, the web support roll 2 is placed slightly shifted upstream of the welding part, which is effective. However, this prevents the force from escaping in the lateral direction. This is especially true when the web material is thin, and welding defects are likely to occur.
さらに、このような線支持の欠点を補うため、
第３図に示すように、上流側に固定板３を設けて
ウエブ材Ｗの逃げを拘束する方法があるが、固

生する、間隙調整に高度の技術を要する、支
持ロール２の接点と固定板の間は支持が不可能で
ある、などの欠点を有している。 Furthermore, in order to compensate for the drawbacks of such line support,
As shown in Fig. 3, there is a method of installing a fixed plate 3 on the upstream side to restrain the escape of the web material W, but since it is a fixed plate, wear occurs due to contact of the web material W, and gap adjustment is required. This method has drawbacks such as requiring a high level of skill and being unable to provide support between the contact point of the support roll 2 and the fixed plate.
この発明は、このような事情に鑑みて提案され
たもので、その目的は、溶接開始点から溶接完了
点までを面支持し得る溶接部支持装置を提供する
ことにある。 The present invention was proposed in view of the above circumstances, and an object of the present invention is to provide a weld support device capable of providing surface support from a welding start point to a welding completion point.
この発明に係る溶接部支持装置は、連続的に供

うに配設したものである。 A welded part support device according to the present invention is provided between upper and lower pressure welding rolls that press a flange material of a welded part in a continuous welded shaped steel manufacturing process in which continuously supplied plate materials are welded to continuously produce welded shaped steel. , an endless track whose raceway surface is in surface contact with the side surface of the web material from at least the welding start point to the welding end point, and which can move and rotate along with the web material due to the frictional force of contact with the web material, with the web material on both sides. It is arranged so that it is held between the two sides.
以下、この発明を図示する一実施例に基づいて
説明する。第４図に示すように、上下圧接ロール

接完了点まで位置するようにされている。 The present invention will be described below based on an illustrated embodiment. As shown in FIG. 4, a total of four endless tracks 4 are disposed between the upper and lower press rolls 1, 1 so as to sandwich the web material W therebetween. The endless track 4 has its raceway surface in surface contact with the side surface of the web material W, and this surface contact portion is located at least from the welding start point to the welding completion point.
第５図に示すように、無限軌道４は、所定間隔

る。 As shown in FIG. 5, the endless track 4 is composed of sprockets 5, 5 spaced apart at a predetermined interval, a chain member 6 wound around the sprockets, and an abutment plate 7 attached to the raceway surface. A guide rail 8 of the chain member 6 is provided internally to receive the lateral forces from the chain member 6. Sprocket 5 and guide rail 8 are mounted on support bracket 9.
このような構成において、無限軌道４は、ウエ
ブ材Ｗの進行とともに従動し溶接部でのウエブ材
Ｗの逃げを完全に拘束、支持することになる。な
お、以上は溶接部の支持について説明したが、こ
れに限らず板材の端面をロール等により加圧成形
する場合にも使用できる。 In such a configuration, the endless track 4 follows the progress of the web material W and completely restrains and supports the web material W from escaping at the welded portion. Note that although the above description has been made regarding support of a welded portion, the present invention is not limited to this, and can also be used when the end face of a plate material is pressure-formed using a roll or the like.
前述のとおりこの発明によれば無限軌道により
ウエブ材を面支持するため次のような効果を奏す
る。 As described above, according to the present invention, since the web material is surface-supported by the endless track, the following effects can be achieved.
溶接部でのウエブ材の逃げを完全に拘束、支
持でき、加熱センターずれ、腰おれ等による溶
接不良を防止できる。 It is possible to completely restrain and support the escape of the web material at the welding part, and prevent welding defects due to heating center deviation, hip sagging, etc.
ウエブ材との接触面積が大きいため単位面積
当りの負荷荷重が小さく部品寿命が長い。 Since the contact area with the web material is large, the load per unit area is small and the life of the parts is long.
回転周長が長いため、特に荷重の強いウエブ
近傍角の摩耗が少なくかつ部品の温度上昇を低
く押えることができる。 Since the rotational circumference is long, there is little wear especially at the corners near the web where the load is strong, and the temperature rise of the parts can be kept low.
高級な材質を必要とせず安価である。 It is inexpensive and does not require high-grade materials.
