Abstract

A method of cutting two members which are to be welded together, along their weld faces before the two members are welded together. A cutting machine provided with two sets of guillotine shears (24), (25), which usually cuts the trailing end of a preceding member (5a) at the same time as the leading end of a following member (5b), is employed so that an end portion of one of the members is first cut by the two sets of guillotine shears, and then the end portion of the other member is cut. Since the two members being welded together are cut separately, it is possible to reduce the load on the shears.

以下、 こ の発 明 を 一実施例 に つ い て 説明 す る 。 こ の発明 に お い て は 、 従来 と 同様 に 一体構成の 2 組 の ギ ロ チ ン シ ヤ ー を 用 い 、 先、 後行鋼帯 5a , 5b の板厚が一定以 下の場合は 、 大 き な 切断力 を 必要 と し な い の で 、 第 5 図 に示す よ う に従来 と 同様 に し て先、 後行鋼帯 5 a， 5b を 第 1 、 第 2 の ギ ロ チ ン シ ヤ ー 24， 25 に よ り 同 時 に切断す る 。 Hereinafter, this invention will be described with reference to an embodiment. In the present invention, two sets of guillotine shears are used in the same manner as before, and when the thickness of the following steel strips 5a and 5b is less than a certain value, than do not require has a significant cutting force, previously in the same manner as conventional Remind as in Figure 5, the trailing steel strip 5 a, 5b are first, second formic b Chi down sheet Cut at the same time with yarns 24 and 25.
第 9 図 、 第 10 図 は 、 先、 後行鋼帯 5a , 5b の板厚 が一定以上 の場合の切断方法 を 示 し て い る 。 先 、 後行鋼帯 5a , 5b が厚板の場合は 、 ま ず、 第 9 図 に 示す よ う に、 先'、 後鋼帯 5aの 後端部 の み を 第 1 の  FIG. 9 and FIG. 10 show a cutting method when the thickness of the leading and trailing steel strips 5a and 5b is equal to or more than a certain value. First, when the succeeding steel strips 5a and 5b are thick plates, first, as shown in FIG. 9, only the rear end of the leading steel strip 5a and the rear steel strip 5a are first.
O ?I 、 WIPO 400095 ギ ロ チ ン シ ヤ ー 24で切断す る 。 つ い で第 10図 に示 す よ う に 、 後行鋼帯 5bの前端部 の み を第 2 の ギ ロ チ ン シ ヤ ー 25に よ っ て切断す る 。 そ う し て従来 と 同様に後行鋼帯 5bを先行鋼帯 5 a側へ前進 さ せ て両 者の切断面 を突合せ、 次工程の レ ー ザ ビ ー ム に よ る 溶接 を 行 う 。 O? I, WIPO 400095 Cutting with guillotine shear 24. Next, as shown in FIG. 10, only the front end of the trailing steel strip 5b is cut by the second guillotine shear 25. Then, as in the conventional case, the succeeding steel strip 5b is advanced to the preceding steel strip 5a, the cut surfaces of both are joined, and welding is performed by the laser beam in the next process.
以上 の よ う に 、 先行鋼帯 5a と 後行鋼帯 5bを順次 に切断す る こ と に よ り 、 ギ ロ チ ン シ ヤ ー の有すべ き 切断力 を 著 し—く 低減で き 、 か つ 、 後行鋼帯 に変 形 を 与 え る こ と 力 な い。  As described above, by sequentially cutting the leading steel strip 5a and the following steel strip 5b, the cutting force to be possessed by the guillotine shear can be significantly reduced. Also, there is no power to deform the subsequent steel strip.
ま た 、 以上 の切断方法に おい て 、 第 1 の ギ ロ チ ン シ ヤ ー 24で先行鋼帯 5a を 切断 し た の ち 、 第 の 上部、 下部 ク ラ ン プ 3 , 4 で先行鋼帯 5a を保持 し た ま ま に す る と 、 切断時に先行鋼帯 5aの板面方向 に作用 し た力 が切断後は な く な る の で 、 第 11 図 に す よ う に先行鋼板 5aの後端が切断線か ら 外方  In the above cutting method, after the leading steel strip 5a is cut by the first guillotine shear 24, the leading steel strip is cut by the first upper and lower clamps 3 and 4. If 5a is held, the force acting in the direction of the plate surface of the preceding steel strip 5a at the time of cutting disappears after cutting, so that as shown in Fig. 11, the leading steel strip 5a Rear end is outside cutting line
( 幅 di ) へ出 る こ と ：^ あ る の 状態 で、 次 に後 行鋼帯 5bの 前端部 を 第 2 の ギ ロ チ ン シ ヤ ー 25 で切 断する と 、 後行鋼帯 5b の切断時 に第 1 の ギ ロ チ ン シ ヤ ー 24 も 切断動作 を 行ぃ 、 第 1 の ギ ロ チ ン シ ャ 一 24に よ っ て先行鋼帯 5a の端部が幅 だ け切断 さ  (Width di): ^ In a certain state, when the front end of the subsequent steel strip 5b is cut with the second guillotine shear 25, the following steel strip 5b is cut. At the time of cutting, the first guillotine shear 24 also performs a cutting operation, and the first guillotine shear 24 cuts only the end of the preceding steel strip 5a by the width.
O PI れ る こ と に な る 。 こ の た め 、 先行鋼帯 5 aの 後端面 が粗雑 に な っ た り 、 切断寸法 の精度が悪 く な る お そ れ力 ^ あ る 。 O PI It will be done. Me other child, preceding the rear end surface of the steel strip 5 a Ri was crudely Tsu name, accuracy Re your its that Do rather than evil forces of cutting dimension ^ Oh Ru.
