産業上の利用分野
本発明は、フラッシュバット、ビード溶接等で所定の構
造に組立てられるシート用のパイプフレームにおける抜
き穴の成形方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for forming punch holes in a sheet pipe frame assembled into a predetermined structure by flash butt, bead welding, or the like.
従来の技術
一般に、シート用のパイプフレームを組立てるには第４
図で示すようにパイプ部材を略四辺形に軸線臼げすると
共に各端末部を溶接し、また、そのパイプフレーム１の
側面下部寄りにサイドフレーム２やアームプレート３を
溶接で取付けることも行われている。また、この溶接を
適用する場合にスパッタ屑がパイプフレームの径内に溜
って異音を発生する原因となるため、それを取除く必要
上からパイプフレーム１の下部横梁部に抜き穴４を設け
ることが行われている。Conventional technology In general, the fourth stage is used to assemble a pipe frame for a seat.
As shown in the figure, the axis of the pipe member is milled into a substantially quadrilateral shape, and each end portion is welded, and the side frame 2 and arm plate 3 are also attached to the lower side of the pipe frame 1 by welding. ing. In addition, when this welding is applied, spatter debris accumulates within the diameter of the pipe frame and causes abnormal noise, so a punch hole 4 is provided in the lower cross beam of the pipe frame 1 in order to remove it. things are being done.
従来、この抜き穴４は第５図で示すようにプレス成形で
丸穴状に抜き落すことにより形成するのが通常である。Conventionally, this punch hole 4 is usually formed by punching out a round hole by press molding, as shown in FIG.
発明が解決しようとする問題点
然し、この抜き穴４の成形方法では打抜き片がパイプフ
レーム１の径内に落ち込み１．それを径内に残存させて
はころげ回って異音を生ずることになるため、極めて手
間の掛る作業で打抜き片をパイプの径内から取出してい
るのが実情である。Problems to be Solved by the Invention However, in this method of forming the punched hole 4, the punched piece falls into the diameter of the pipe frame 1.1. If they remain in the diameter of the pipe, they will roll around and produce abnormal noises, so the reality is that the punched pieces are removed from the diameter of the pipe, which is an extremely time-consuming process.
問題点を解決するための手段
本発明に係る抜き穴の成形方法においては、パイブフレ
ームの径内にフレーム面を切り曲げて切欠片を開口縁に
部分的に連結させた抜き穴をバイブフレームの適宜な軸
線上に形成するようにされている。Means for Solving the Problems In the method for forming a punched hole according to the present invention, the punched hole of the vibe frame is formed by cutting and bending the frame surface within the diameter of the pipe frame and partially connecting the cutout piece to the opening edge. It is arranged to be formed on an appropriate axis.
作 用
この抜き穴の成形方法では、切欠片を部分的に開口縁に
連結することによりバイブフレームの径内に残存させる
から、切欠片を抜き屑として取出す必要がないばかりで
なく、その抜ぎ穴をスパッタ屑の十分に除去可能な開口
として形成できるようになる。Function: In this punch hole forming method, the notch pieces are left within the diameter of the vibe frame by being partially connected to the opening edge, so not only is it not necessary to take out the cut pieces as scraps, but also the cutout pieces can be removed easily. The hole can be formed as an opening that allows sufficient removal of sputter debris.
実施例
以下、第１〜３図を参照して説明すれば、次の通りであ
る。An example will be described below with reference to FIGS. 1 to 3.
この抜き穴の成形方法はシート用のバイブフレームにス
パッタ屑を取除く開口を形成するのに適用するものであ
り、そのシートフレームは第４図で示すと同様にバイブ
部材を略四辺形に折曲げて端末間を接合すると共に、側
面下部側にサイドフレームやアームプレートを取付ける
ことにより組立てられている。This hole forming method is applied to form an opening for removing spatter debris in a vibrator frame for a seat, and the seat frame is made by folding the vibrator into a substantially quadrilateral shape as shown in It is assembled by bending and joining the ends and attaching the side frame and arm plate to the lower side of the side.

うにフレーム面を切り曲げることにより切欠片１２を開
口縁に部分的に連結させてバイブフレーム１０の径内に
曲げ込み、しかも開口縁から直立状に起立させて成形す
るとよい。For this assembly, it is preferable to use flash hat, bead, etc. welding, so that the ends of the vibrator members can be joined together and the side frames, arm plates, etc. can be easily attached. As shown in FIG. 1, the seat frame is provided with a hole 11 by opening the frame surface in the lower cross beam portion of the vibe frame 10, so that sputtered debris can be discharged and removed through the hole 11. The punch hole 11 can be opened by bending the vibe frame 10 into a substantially quadrilateral shape and performing the same pressing process. Further, as shown in Fig. 2.3, this punch hole 11 is formed by cutting and bending the frame surface so that the notch piece 12 is partially connected to the opening edge and bent into the diameter of the vibe frame 10, and is also formed from the opening edge. It is best to form it in an upright position.
このようにして抜き穴１１を成形するときには切欠片１
２が部分的に開口縁と連結されてバイブフレーム１０の
径内に残存するから、それを抜き取らなくても異音を発
生する原因とはならない。When forming the punch hole 11 in this way, the notch piece 1
2 is partially connected to the opening edge and remains within the diameter of the vibe frame 10, so even if it is not removed, it will not cause abnormal noise.
また、この抜き穴１１はスパッタ屑を取除くのに必要な
十分に大きな口径でバイブフレーム１０に形成でき、ま

ッタ屑の遮り壁として作用することによりスパッタ屑を
確実に径外に排出することを補助できるようになる。In addition, this punch hole 11 can be formed in the vibe frame 10 with a sufficiently large diameter necessary to remove spatter debris, and if the notch piece 12 is formed in an upright manner, press forming is not only easy. Instead, when the sputtered debris is passed around and discharged to the opening edge side where the notch piece 12 is not located, it acts as a blocking wall for the sputtered debris, thereby assisting in reliably discharging the sputtered debris to the outside of the diameter.
