The present invention relates to providing a lightweight and highly safe bumper line hose by using a pamper line hose. Landscape technology
従来のバンパーリインホースは厚肉の概略 C字形断面のものを使用する場 合が多かった。 また高張力鋼板を使用し閉断面に加工した発明としては、 日 本国特許番号第 2 8 4 6 9 8 3号が知られている。  Conventional bumper rein hoses often have a thick C-shaped cross section. Also, as an invention in which a high-strength steel sheet is used to form a closed cross section, Japanese Patent No. 28466983 is known.
厚肉の概略 C字形断面のものは断面強度を確保するため重量的に重くせざ るを得ず、 これを使用すると自動車に要求される加速性能や燃費の経済性を 低下させるだけでなく、 燃料エネルギを多量に消費することに伴い大気汚染 物質を多量に排出し、 地球環境を保全しょうとする現代の社会的要請に反し ていた。  Thick, roughly C-shaped cross sections must be made heavier in weight to ensure cross-sectional strength, and using them not only reduces the acceleration performance and fuel economy required for automobiles, Consumption of a large amount of fuel energy emitted a large amount of air pollutants, which was contrary to modern social demands to protect the global environment.
また、 厚肉の概略 C字形断面のものは水平フランジ部が挫屈すると急激に 破壌するため、 正常にエアーパックを作動させるため高度の配慮を要し、 適 正に構成されなかつた場合には、 自動車が衝突したときに充分その性能が発 揮できなかった。  Thick, roughly C-shaped cross-sections break rapidly when the horizontal flange buckles, requiring a high degree of care to operate the air pack properly, and should not be properly constructed. Did not fully demonstrate its performance when a car collided.
一方、 特許番号第 2 8 4 6 9 8 3号はロール成形で概略 D字形の閉断面を 有するバンパーリインホースを提供するが、 概略 D字形の閉断面では前面と 後面を繋ぐ部材が 2本しかなく断面強度が低くなる。 そのため、 同じ断面強 度のバンパーリインホースを得るためには、 板厚の厚い素材を使用する必要 があり、 重量的に重いものにせざるを得なかった。 On the other hand, Patent No. 2 8 4 6 9 8 3 has a roughly D-shaped closed cross section by roll forming. Although a bumper rein hose is provided, the cross section strength is low because there are only two members connecting the front and rear surfaces in a roughly D-shaped closed cross section. Therefore, in order to obtain a bumper rein hose with the same cross-sectional strength, it was necessary to use a thick material, which had to be heavy.
またバンパーリインホースには、 必要な強度を有しつつ衝突時のエネルギ を吸収する機能、 特に両端部には衝突時に適度な荷重で挫屈する、 などの機 能を満足しつつ自動車の走行性能や燃費性能を向上するため、 さらなる軽量 化の要請があつたがなかなか達成できなかった。  Also, the bumper rein hose has the function of absorbing the energy at the time of the collision while having the necessary strength, especially the functions of buckling with an appropriate load at the both ends at the time of the collision. There was a demand for further weight reduction to improve fuel efficiency, but this was not easily achieved.
さらに、 自動車の構造上の要請や顧客の好みに合わせる外観形状からの要 請により、 長手方向のキャンバー曲げ加工の曲げ半径を小さくする要請があ つたが、 曲げ半径を小さくすると曲げの内側にあたる面に変形が生じ、 しか もその変形が一定しないため同一品質のバンパーリインホースを安定して製 作することができなかった。  In addition, there was a request to reduce the bending radius in the longitudinal camber bending process in response to the structural requirements of the car and the demand for an external shape that matched the customer's preference. As a result, the bumper rein hose of the same quality could not be manufactured stably because the deformation was not constant.
本発明は、 上記した従来技術の欠点を除くためなされたものであって、 そ の目的とするところは、 高張力鋼板を使用し所定の工程により製造された、 軽量で安全性の高い概略 B字形の閉断面を有する、 バンパーリインホースを 提供することにある。  The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. It is an object of the present invention to provide a lightweight and highly safe outline B manufactured by a predetermined process using a high-tensile steel plate. An object of the present invention is to provide a bumper rein hose having a closed cross section of a letter shape.
また他の目的は、 断面強度が求められる部分にのみビードを付けて強度を 高め、 適当な荷重で挫屈することを求められる部分にはビードを付け加えな い構造として、 さらに軽量で安全性の高いバンパーリインホースを提供でき るようにすることにある。  Another purpose is to increase the strength by attaching beads only to the parts where the cross-sectional strength is required, and to add no beads to the parts required to buckle with an appropriate load. The purpose is to provide a bumper rein hose.
また他の目的は、 キャンパー曲げ加工の曲げ半径を小さくした、 同一品質 のバンパーリィンホースを安定して製作できるようにすることにある。 発明の開示  It is another object of the present invention to stably produce a bumper line hose of the same quality with a reduced bending radius of a camper bending process. Disclosure of the invention

ここまでの工程で概略 B形の閉断面 5 1は完成し、 直線のバンパーリイン ホースとして使用される。  By the process up to this point, the B-shaped closed cross section 51 is completed and used as a straight bumper rein hose.
平面視長手方向のキャンバー曲げ加工する工程は、 バンパーリインホース 1、 2、 3の前面 6 1、 6 2、 6 3と同じ長手方向の形状を有する上型と、 後面 6 5、 6 6、 6 7と同じ長手方向の形状を有する下型との間に、 閉断面 5 1をはさみ上型を押し下げプレス加工するように構成する。  The process of bending the camber in the longitudinal direction in plan view includes the upper die having the same longitudinal shape as the front surfaces 61, 62, 63 of the bumper rein hoses 1, 2, 3 and the rear surface 65, 66, 6 A closed cross section 51 is sandwiched between the lower die and the lower die having the same shape in the longitudinal direction, and the upper die is pressed down and pressed.

あらかじめかしめ接合や仮溶接を行つた後に、 本溶接や平面視長手方向の ：一曲げ加工を行うのは、 本溶接のときに断面形状を一定に保っため 及び平面視長手方向のキャンバー曲げ加工により断面形状がくずれるのを防 止するために仮接合するものである。 従って、 かしめ接合や仮溶接は通常 1 0 0〜 3 0 0 mmのピッチで行えばよレヽ。 After performing caulking and temporary welding in advance, : The single bending process is to temporarily join in order to keep the cross-sectional shape constant during the main welding and to prevent the cross-sectional shape from being broken by the camber bending process in the longitudinal direction in plan view. Therefore, caulking or temporary welding may be usually performed at a pitch of 100 to 300 mm.
バンパーリインホース 2、 の後面 6 6やパンパ一リインホース 3の前面 6 3と後面 6 7などにビード 6、 7、 8、 9を施す場合は、 断面中央にハツ ト形をプレス加工する工程 （F I G . 9参照） において、 上下のプレス型を 幅広くしてそれぞれの位置に、 あらかじめビード形状 6、 7、 8、 9の形状 に合わせた溝や突起を付け加えたものを使用する。 ビードを断続的に施す場 合は、プレス型のビード形状用の溝や突起を断続的に構成した型を使用する。 平面視長手方向のキャンパー曲げ加ェする場合において、 曲げ半径 Rを小 さくすると内側にあたる後面に変形が生じ、 しかもその変形が一定しない問 題があつたが、 キャンパー曲げ加工部の内側の後面 6 6にビードを断続して 施した後に、 キャンバー曲げ加工を行うと変形はビードのとぎれ部 5に生じ 変形の形状も一定した。このため、一定の変形は容認する必要はあるものの、 同一の品質を有するパンパ一リィンホースを安定して製作することができる ようになった。  When beads 6, 7, 8, 9 are applied to the rear surface 66 of the bumper rein hose 2, 6 or the front surface 63, the rear surface 67 of the bumper rein hose 3, etc., a step of pressing a hat shape at the center of the cross section (FIG. 9)), use the upper and lower press dies wide and add grooves and projections in advance to the respective positions to match the bead shapes 6, 7, 8, and 9. If the beads are to be applied intermittently, use a press-type die with bead-shaped grooves or projections intermittently configured. When bending the camper in the longitudinal direction in plan view, if the bending radius R is reduced, the inner rear surface is deformed and the deformation is not constant. When the camber bending process was performed after intermittently applying the bead to 6, the deformation occurred at the break 5 of the bead, and the shape of the deformation was constant. For this reason, although it is necessary to tolerate certain deformations, it has become possible to stably produce pump-line hoses having the same quality.
なを、 高張力鋼板としては引張強さ 6 0〜 1 2 0 k g f /mm 2のものが 適当であるが、 特に引張強さ 1 0 0〜 1 2 0 k g f /mm 2 のものが軽量化 の要求に応えるため及び経済性の理由から好ましい。 高張力鋼板の板厚は 0 . 7〜1 . 6 mmのものが適当であるが、 特に板厚 0 . 9〜1 . 4 mmの ものが軽量化の要求に応えるため及び経済性の理由から好ましい。 Although high tensile strength steel sheets with a tensile strength of 60 to 120 kgf / mm 2 are suitable, those with a tensile strength of 100 to 120 kgf / mm 2 are particularly lightweight. Preferred for meeting demand and for economic reasons. A high-strength steel sheet with a thickness of 0.7 to 1.6 mm is appropriate, but a sheet with a thickness of 0.9 to 1.4 mm is particularly suitable to meet the demand for weight reduction and for economic reasons. preferable.

Industrial applicability
本発明に係るバンパーリインホースは、 断面係数が高く強度上優れた形状 となっているため、 より薄い高張力鋼板を使用することができる。 従って、 必要な強度と衝突時のエネルギ吸収などの機能を満足しつつ、 軽量化の要請 に応えたバンパーリインホースとすることができ、 産業上の利用性は高い。 また、 断面両側からプレス加工しハツト形上面と前面中央部の一部とをか しめ接合する工程の後に、 平面視長手方向のキャンパー曲げ加工する工程を 行い最後に溶接する工程とした場合は、 プレス加工のすべてを完了した後に 溶接加工をすることになる。 このため、 多工程のプレス加工を一台で行うこ とのできるトランスファプレスなどを使用することが可能となり、 設備のラ イン構成が単純化されスペースの効率的な利用が可能となった。 さらに、 設 備及ぴバンパーリインホースの製作費用の低減が可能となった。 このため産 業上の利用性は高い。  Since the bumper rein hose according to the present invention has a high section modulus and a shape excellent in strength, a thinner high-tensile steel sheet can be used. Therefore, a bumper rein hose that satisfies the required strength and functions such as energy absorption at the time of a collision, and that meets the demand for lighter weight, is highly industrially applicable. In addition, after the process of pressing from both sides of the cross-section and caulking the upper surface of the hat and part of the center of the front surface, performing the process of camper bending in the longitudinal direction in plan view, and finally the process of welding, After all of the press work is completed, welding work will be performed. For this reason, it was possible to use a transfer press or the like that can perform multiple steps of press working with a single unit, simplifying the equipment line configuration and enabling efficient use of space. In addition, it has become possible to reduce the production costs of equipment and bumper rein hoses. Therefore, industrial applicability is high.
また、その前面や後面などにビードを付け加えたパンパ一リインホースは、 断面強度が求められる部分のみ強度を高め、 適当な荷重で挫屈することを求 められる部分にはビードを付け加えない構造とすることにより、 必要な強度 と衝突時のエネルギ吸収などの機能を満足しつつ、 さらなる軽量化の要請に 応えたバンパーリインホースであるので産業上の利用 1"生は高い。 Also, for pump-in hoses with beads added to the front and rear surfaces, it is necessary to increase the strength only in sections where cross-sectional strength is required, and to buckle with an appropriate load. By using a structure that does not add a bead to the part where it can be used, it is a bumper rein hose that meets the demand for further weight reduction while satisfying the required strength and functions such as energy absorption at the time of collision, so it is used for industrial use 1 "raw is expensive.
また、 平面視長手方向のキャンバー曲げ部の内側にあたる後面にビードを 断続的に施したバンパーリインホースは、 後面の一定の位置に一定の形状の 変形を容認する必要はあるものの、 キャンバー曲げ半径 Rを小さくした同一 品質のバンパーリインホースを安定して製作できるようになった。 このため 小さな曲げ半径のものが提供できるようになり産業上の利用性は高い。 また、 高張力鋼板を使用し、 断面を概略 U字形にプレス加工する第 1工程 と、 断面中央にハット形をプレス加工する第 2工程と、 断面両端に立ち上が りをプレス加工する第 3工程と、 断面両側に概略山形鋼形状の斜め立ち上が りをプレス加工する第 4工程と、 断面両側からプレス加工する第 5工程と、 接合部を溶接する第 6工程とからなる、 概略 B字形の閉断面を有するバンパ ーリインホースを製造する方法は、 新たな製造方法を提供するものであって 産業上の利用性は高い。  In addition, the bumper rein hose with bead intermittently applied to the rear surface inside the camber bend in the longitudinal direction in plan view requires a camber bending radius R, although it is necessary to allow a certain shape deformation at a certain position on the rear surface. It is now possible to stably produce bumper rein hoses of the same quality with a reduced size. For this reason, a product with a small bending radius can be provided, and its industrial applicability is high. In addition, the first step of pressing the cross section into a roughly U-shape using a high-tensile steel sheet, the second step of pressing a hat shape at the center of the cross section, and the third step of pressing the rising at both ends of the cross section The outline B is composed of a fourth step of pressing an oblique rising of a roughly angle iron shape on both sides of the cross section, a fifth step of pressing from both sides of the cross section, and a sixth step of welding the joint.
