범퍼빔 보강재 고정용 지그 및 이 지그를 이용하여 제조된 하이브리드 범퍼빔{JIG FOR FIXING STIFFENER USING IN THE BUMPER BEAM AND HYBRID BUMPER BEAM MANUFACTURED USING THAT JIG}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bumper beam stiffener fixing jig and a hybrid bumper beam manufactured using the jig,

본 발명은 범퍼빔 보강재 고정용 지그 및 이 지그를 이용하여 제조된 하이브리드 범퍼빔에 관한 것으로, 보다 상세하게는 범퍼빔의 충돌성능 향상을 위해 스틸재를 인서트 성형하여 강도를 보강하되, 인서트 성형시 위치 틀어짐을 막아 정위치에 인서트되게 함으로써 강도 보강 기능을 극대화시킬 수 있도록 한 범퍼빔 보강재 고정용 지그 및 이 지그를 이용하여 제조된 하이브리드 범퍼빔에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jig for fixing a bumper beam stiffener and a hybrid bumper beam manufactured using the jig. More particularly, the present invention relates to a hybrid bumper beam for reinforcing strength by insert- The present invention relates to a jig for fixing a bumper beam stiffener and a hybrid bumper beam manufactured by using the jig for maximizing the strength reinforcing function by preventing a positional error and inserting the bumper beam into a predetermined position.

일반적으로, 자동차용 범퍼 시스템은 자동차의 저속 충돌시 탄성적으로 변형하여 자동차의 물리적인 손상을 최초화하기 위한 것으로서, 다른 자동차나 고정체와의충돌시 그 충격을 흡수하여 탑승자의 안전을 도모하게 되며, 동시에 차체의 변형을 최소화 할 수 있도록 자동차 전,후방에 배치되는 완충수단이다.Generally, a bumper system for an automobile is designed to elastically deform at the time of a low-speed collision of an automobile to initialize the physical damage of the automobile, thereby absorbing the impact of collision with another automobile or a fixed body, , And a shock absorber disposed at the front and rear of the vehicle so as to minimize deformation of the vehicle body at the same time.

일 예로, 도 1과 같이 자동차용 범퍼빔 시스템은 범퍼커버(1)와 'C' 형상의 범퍼빔(2) 사이에 충격에너지의 흡수를 위한 에너지업소버(3)가 개재되며, 스테이(4)에 의해 범퍼빔(2)이 고정된 구조로 이루어진다.1, an automotive bumper beam system includes an energy absorber 3 for absorbing impact energy between a bumper cover 1 and a 'C' shaped bumper beam 2, And the bumper beam 2 is fixed by the bumper beam 2.

그리하여, 자동차 충돌시 범퍼커버(1)로부터 전달된 충격은 먼저 에너지업소버(3)에서 탄성적으로 흡수된 후 다음 강성을 갖는 범퍼빔(2)에 의해 차단되며, 이를 통해 차체의 변형을 최소화시킴으로써 탑승자의 안전을 확보하게 된다.Thus, the impact transmitted from the bumper cover 1 in the event of an automobile collision is first elastically absorbed in the energy absorber 3 and then blocked by the bumper beam 2 having the next rigidity, thereby minimizing the deformation of the vehicle body Thereby ensuring the safety of the passenger.

따라서, 범퍼 시스템에 대한 법규는 매우 엄격하며, 특히 유럽 시장의 경우에는 요구사항이 매우 까다롭고 더 엄격하다.Therefore, the regulations on bumper systems are very strict, especially in the European market, the requirements are very demanding and more stringent.

예컨대, 유럽 사양의 경우 요구 스펙(Spec)은 ECE R42 테스트 및 풀 배리어(Full Barrier) 테스트, RCAR 배리어 테스트 등이 있는데, 특히 RCAR 배리어 테스트의 경우 최근 관련 규정이 더욱 강화되면서 이를 만족시킬 필요성이 대두되었다.For example, in the case of the European specification, the required specifications are the ECE R42 test, the full barrier test, the RCAR barrier test, etc. In particular, in the case of the RCAR barrier test, .

이와 관련하여, 공개특허 제2011-0013602호가 개시되어 있지만, 충돌흡수력, 강도 측면에서 테스트를 만족시키지 못하는 경우가 많았다.In this connection, although Japanese Laid-Open Patent Publication No. 2011-0013602 is disclosed, there are many cases in which the test is not satisfied in terms of collision absorbing power and strength.

더구나, 차량 경량화를 위해 개발 적용 중인 유리섬유 강화 열가소성수지(이하 'GMT'라 함) 사용시 충돌 형태에 따른 국부적인 강도 보강이 요구되고 있지만, 통상적인 강도 보강 구조는 주로 국부적으로 리브(Rib)를 세우는 정도에 불과하여 사실상 강도 보강에 한계가 있었다.
In addition, while the use of glass fiber reinforced thermoplastic resin (hereinafter referred to as "GMT") under development for the light weight of vehicles is required to reinforce local strength according to the type of collision, a typical strength reinforcing structure is mainly composed of ribs But it was limited to the extent of reinforcement.

본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 범퍼빔의 충돌성능 향상을 위해 스틸재를 인서트 성형하여 강도를 보강하되, 인서트 성형시 위치 틀어짐을 막아 정위치에 인서트되게 함으로써 강도 보강 기능을 극대화시킬 수 있도록 한 범퍼빔 보강재 고정용 지그 및 이 지그를 이용하여 제조된 하이브리드 범퍼빔을 제공함에 그 주된 목적이 있다.
SUMMARY OF THE INVENTION [0008] The present invention has been made in view of the above-described problems in the prior art, and it is an object of the present invention to provide a bumper beam which is formed by inserting a steel material to reinforce the bumper beam, A bumper beam stiffener fixing jig for maximizing the strength reinforcing function by inserting the bumper beam reinforcement into the bumper reinforcement, and a hybrid bumper beam manufactured using the jig.

본 발명은 상기한 목적을 달성하기 위한 수단으로, 하형, 하형과형합되는 상형을 이용하여 GMT 소재 사이에 스틸보강재를인서트시켜범퍼빔을 성형할 때, 상기 스틸보강재의 일부에 홀을 형성하고, 상기 홀에 끼워지는 지그핀을 상기 하형의 일부에 설치한 것을 특징으로 하는 범퍼빔보강재 고정용 지그를 제공한다.As a means for achieving the above object, the present invention provides a method of manufacturing a bumper beam by inserting a steel reinforcement material between GMT materials using a lower mold and a lower mold to form a hole in a part of the steel reinforcement, And a jig pin fitted in the hole is provided in a part of the lower mold.

이때, 상기 지그핀은 상하유동 가능한 스프링가이드핀 형태인 것에도 그 특징이 있다.At this time, the jig pin is also in the form of a spring guide pin which can move up and down.

또한, 상기 스틸보강재에 형성되는 홀은 상기 지그핀의 직경보다 크게 형성된 것에도 그 특징이 있다.Further, the hole formed in the steel reinforcement is characterized by being formed larger than the diameter of the jig pin.

뿐만 아니라, 상기 지그핀은 하형에 형성된 높이제한턱에 의해 돌출 높이가 제한되어 스틸보강재까지만 끼워지는 것에도 그 특징이 있다.In addition, the height of the jig pin is restricted by the height restricting jaw formed on the lower die, so that only the steel reinforcement is inserted.

아울러, 상기 지그핀은 성형될 범퍼빔의 양단부에 위치되는 것에도 그 특징이 있다.In addition, the jig pin is also located at both ends of the bumper beam to be molded.

그리고, 본 발명은 상기에 기재된 범퍼빔보강재 고정용 지그를 이용하여 범퍼빔의 수평단면부 정중앙에 인서트 된스틸보강재를 구비하여 제조된 것을 특징으로 하는 하이브리드범퍼빔도 제공한다.
The present invention also provides a hybrid bumper beam which is manufactured by using a jig for fixing a bumper beam stiffener and a steel reinforcement inserted in the center of the horizontal section of the bumper beam.

본 발명에 따르면, 스틸을 정확한 위치에 인서트할 수 있어 품질 안정화를 달성하고, 충돌안정성을 확보하며, 금형의 내구성을 높일 수 있다.INDUSTRIAL APPLICABILITY According to the present invention, it is possible to insert steel at an accurate position, thereby achieving quality stabilization, ensuring collision stability, and enhancing durability of a mold.

또한, 범퍼빔의 충돌성능을 강화함으로써 복합소재의 기본 특성에 스틸의 강성까지 더한 새로운 개념의 고강도 범퍼빔을 만들 수 있다.
In addition, by reinforcing the impact performance of the bumper beam, a new concept of a high strength bumper beam can be made that adds to the rigidity of the steel to the basic properties of the composite material.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

또한, 본 발명의 개념에 따른 실시예는 다양한 변경을 가할 수 있고 여러 가지 형태를 가질 수 있으므로, 특정 실시예들은 도면에 예시하고 본 명세서에 상세하게 설명하고자 한다. 그러나, 이는 본 발명의 개념에 따른 실시예들을 특정한 개시 형태에 한정하려는 것이 아니며, 본 발명의 사상 및 기술 범위에 포함되는 모든 변경물, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

본 발명과 관련하여 본 발명자들은 상술한 종래 문제를 해결하기 위해 도 2의 예시와 같이, GMT 소재로 된 범퍼빔(100)의 일부 단면, 더욱 바람직하기로는 범퍼빔(100)의 수평단면부(110)에 일정길이 스틸보강재(200)를 인서트 성형하여 강도를 보강키 위한 시도를 개시한 바 있다.In order to solve the above-mentioned conventional problems, the inventors of the present invention have found that, as an example of FIG. 2, a partial cross section of a bumper beam 100 made of a GMT material, more preferably a horizontal cross section of a bumper beam 100 110 to insert a certain length of steel reinforcement 200 to reinforce the strength.

그렇지만, 예상과 달리 GMT 소재로 범퍼빔(100)을 만들기 위해 적층 성형하면서 스틸보강재(200)를 인서트시킬 때 이를 잡아주는 수단이 없어 성형과정에서 밀려 성형 후 도 2의 예시와 같은 형태로 수평단면부(110)에 센터링된 상태로 위치해야 할 스틸보강재(200)가 수직단면부(120)까지 밀려가 정위치되지 못하고, 편심됨으로써 보강 기능이 유명무실화될 뿐만 아니라, 오히려 재료의 기계적 강도를 떨어뜨려 국부적인 파단 가능성을 증대시키는 예상치 못한 문제를 초래하였다.However, unexpectedly, there is no means for catching the steel reinforcement 200 when it is laminated while forming the bumper beam 100 in order to make the bumper beam 100 as GMT material, The steel reinforcement 200 to be positioned in a state where the steel reinforcement 200 is centered on the portion 110 is pushed up to the vertical section 120 and is not properly positioned and eccentrically not only becomes reinforcing function but also reduces the mechanical strength of the material Resulting in unexpected problems that increase the likelihood of local failure.

이에 본 발명자들은 연구에 연구를 거듭하여, 도 3과 같은 형태로 스틸보강재(200)를 정위치시킬 수 있는 방안을 완성하게 되었다.Accordingly, the inventors of the present invention have repeatedly carried out researches and have completed a method for positioning the steel reinforcement 200 in the form as shown in FIG.

본 발명은 도 3에서와 같이, 스틸보강재(200)를 인서트시켜 범퍼빔(100)으로 성형할 때 상기 스틸보강재(200)를 특정위치에 고정시킬 수 있도록 한 지그를 제공한다.3, the present invention provides a jig capable of fixing the steel reinforcement 200 to a specific position when the steel reinforcement 200 is inserted into the bumper beam 100, as shown in FIG.

이를 위해, 본 발명에서는 상기 범퍼빔(100)의 주된 충돌부위가 아닌 사이드, 즉 양측단부에서 인서트 성형시 상기 스틸보강재(200)를 잡아줄 수 있는 지그핀(300)을 구비한다.To this end, the present invention includes a jig pin 300 that can hold the steel stiffener 200 at the side, that is, both ends of the bumper beam 100, which is not the main collision site of the bumper beam 100 during insert molding.

이때, 상기 지그핀(300)은 금형 중 하형(410)의 상면으로부터 일정깊이 매립된 상태로 구비되거나 혹은 하형(410)의 일부를 상하로 관통시킨 후 그 속에 설치될 수 있다.At this time, the jig pin 300 may be embedded in the mold 410 at a certain depth from the upper surface of the lower mold 410, or may be installed in the lower mold 410 after passing the lower mold 410 through the upper and lower portions.

특히, 상기 지그핀(300)은 일정 높이만 상승할 수 있도록 높이제한턱(310)에 의해 상승높이가 제한되게 구성되므로 정확하게 인서트되는 스틸보강재(200)까지만 끼워질 수 있도록 구성된다.In particular, since the height of the jig pin 300 is limited by the height restricting jaw 310 so that the jig pin 300 can be raised only by a predetermined height, the jig pin 300 can be inserted only into the steel reinforcement 200 which is accurately inserted.

이 경우, 상기 지그핀(300)은 다양한 형태의 승하강수단, 이를 테면 실린더 등에 의해 승하강되도록 구성될 수 있지만, 가장 바람직한 예로는 상형(400)을 손상시키지 않으면서 스틸보강재(200)만을 정확하게 위치고정할 수 있도록 스프링가이드핀 형태를 사용한다.In this case, the jig pin 300 may be configured to be raised and lowered by various types of elevating and lowering means, such as a cylinder, but most preferably, Use spring guide pin type to fix position.

스프링가이드핀 형태의 지그핀(300)은 지그핀(300)의 일부에 스프링이 끼워져 탄성적으로 승하강될 수 있도록 구성된 것을 말하며, 설명상 도면에서는 표시를 생략하였다.The jig pin 300 in the form of a spring guide pin is configured such that a spring is fitted to a part of the jig pin 300 so that the jig pin 300 can be elastically lifted and lowered.

이는 상형(400)이 하강하여 하형(410)과 형합되면서 성형될 제품형상의 공간인 캐비티(420)에 안착되어 있는 GMT를 가압하여 할 때 그 힘에 의해 일부 눌리면서 하방향으로 움직일 수 있게 함으로써 상형(400)에 영향을 미치지 않도록 구성한다는 것을 의미한다.When the upper mold 400 is lowered and is engaged with the lower mold 410 to press the GMT that is seated on the cavity 420 which is a space of the product shape to be formed, (Not shown).

그리고, 본 발명이 적용되기 위해서는 상기 스틸보강재(200)의 대응개소에 홀(도면번호 생략)이 형성되어 있어야 한다.In order to apply the present invention, a hole (not shown) should be formed at a corresponding portion of the steel reinforcement 200.

그래야, 상기 지그핀(300)이 끼워질 수 있기 때문이다.This is because the jig pin 300 can be fitted.

이때, 상기 홀은 상기 지그핀(300)과 대응되거나 혹은 더 크게 형성되도록 하여 작업효율을 높이도록 함이 바람직하다.At this time, it is preferable that the hole is formed to correspond to or larger than the jig pin 300, thereby improving the working efficiency.

다만, 도시된 예에서는 지그핀(300)의 상단에 단턱을 두어 상기 홀과 정확하게 맞물려 일종의 홀 끼움 걸림구조를 갖추도록 한 것으로 보여 주지만, 이는 가장 바람직한 예에 불과하며, 이를 포함한 형태로 지그핀(300)이 스틸보강재(200)의 홀에 끼워지기만 하면 된다.However, in the illustrated example, it is shown that the jig pin 300 is provided at the upper end of the jig pin 300 so as to accurately engage with the hole so as to have a kind of hooking structure. However, this is the most preferable example, 300 are inserted into the holes of the steel reinforcement 200.

즉, 범퍼빔(100) 성형을 위해 먼저 GMT를 캐비티(420) 내부에 한 층을 깐다.That is, to form the bumper beam 100, a layer of GMT is first placed inside the cavity 420.

이때, GMT는 성형을 위해 예열되어 연질화되어 있는 상태이다.At this time, GMT is in a state of being preheated and softened for molding.

때문에, 상기 지그핀(300)은 상기 GMT의 일부를 뚫고 상부로 노출되기 쉽다.Therefore, the jig pin 300 is likely to penetrate a portion of the GMT and be exposed upward.

이어, 스틸보강재(200)를 GMT 상부에 안착시키되, 상기 지그핀(300)의 위치에 홀을 맞춰 끼우는 형태로 배치한다.Then, the steel reinforcement 200 is seated on the upper part of the GMT, and the steel reinforcement 200 is disposed in such a manner as to fit the hole at the position of the jig pin 300.

그런 다음, 스틸보강재(200) 상부에 또다른 GMT를 재치시킨 상태에서 상형(400)을 하강하여 가압 성형한다.Then, the upper mold 400 is lowered and pressure-molded in a state where another GMT is placed on the upper portion of the steel reinforcement 200.

그러면, 스틸보강재(200)가 센터링된 상태로 정확한 위치에 고정된 채 인서트성형되게 된다.Then, the steel reinforcement 200 is insert-molded while being fixed at the correct position in a centered state.

이때, 스틸보강재(200)를 포함한 GMT 및 지그핀(300)이 압하력을 받게 되지만, 지그핀(300) 자체가 탄성유동가능하게 구성되어 있으므로 지그핀(300)이 손상되거나 혹은 반대로 상형(400)이 손상되는 일은 발생하지 않게 된다.At this time, the GMT including the steel reinforcement 200 and the jig pin 300 are subjected to the downward force. However, since the jig pin 300 itself is configured to be elastically flowable, the jig pin 300 may be damaged, ) Is not damaged.

이와 같이, 본 발명은 아주 간단한 개념인 지그핀(300)을 더 구비함으로써 스틸보강재(200)을 정확한 위치에 편심되지 않게 인서트 성형할 수 있어 범퍼빔(100)의 충돌성능을 향상시키는데 일조하게 된다.
As described above, the present invention further includes the jig pin 300, which is a very simple concept, so that the steel reinforcement 200 can be insert-molded without being eccentrically positioned at an accurate position, thereby improving the impact performance of the bumper beam 100 .
