[0002]

본 발명은 연속섬유 열가소성수지(CFT)를 이용해서 차량용 백빔을 제작하는 방법 및 그 제조방법으로 제작된 차량용 범퍼 백빔에 관한 기술이다.
The present invention relates to a method for manufacturing a vehicle back beam using a continuous fiber thermoplastic resin (CFT) and a technique for a vehicle bumper back beam manufactured by the manufacturing method.

However, due to the weight increase and deterioration of fuel consumption, recently, a composite material of plastic and steel, Background Art [0002] A back beam produced by arranging a plurality of resin (CFT: Continuous Fiber Thermoplastics) rods is mainly used.

연속섬유 열가소성수지(CFT)를 이용해서 백빔을 제작하는 종래의 제조방법은 도 1에 도시된 바와 같이 다수의 보빈(1)에 감겨진 유리섬유 강화플라스틱(2, FRP; fiber glass reinforced plastic)을 인발하여 합성수지(3)가 용융되어 있는 함침조(4)에 통과시켜서 연속섬유 강화 열가소성 플라스틱 테이프(5)로 제작하고, 상기 연속섬유 강화 열가소성 플라스틱 테이프(5)를 히팅기(6)와 성형기(7)로 통과시켜서 연속섬유 강화 열가소성 플라스틱 로드(8)로 제작하고, 상기 연속섬유 강화 열가소성 플라스틱 로드(8)를 냉각기(9) 및 인취기(10)로 통과시킨 후 컷팅기(11)를 이용해 일정 길이로 절단한다.A conventional manufacturing method for manufacturing a back beam using a continuous fiber thermoplastic resin (CFT) is a method in which a glass fiber reinforced plastic (FRP) 2 wound around a plurality of bobbins 1 The continuous fiber-reinforced thermoplastic resin tape 5 is passed through the impregnation tank 4 in which the synthetic resin 3 is melted to form the continuous fiber-reinforced thermoplastic plastic tape 5, 7 to form a continuous fiber-reinforced thermoplastic plastic rod 8 and passing the continuous fiber-reinforced thermoplastic plastic rod 8 through a cooler 9 and a drawer 10, Cut to length.

그리고, 일정 길이로 절단된 다수개의 연속섬유 강화 열가소성 플라스틱 로드(8)를 스태커(12; stacker)에 적재 배열하고, 스태커(12)에 적재된 상태로 오븐(13)에 통과시킨 후 프레스 금형(14)을 이용해서 백빔의 형상으로 제작하고, 이후에 냉각기(15)와 드릴링머신(16)으로 후 가공을 한 다음, 최종적으로 랙(17)에 형상 제작이 완료된 완제품의 백빔(20)을 적재하게 된다.A plurality of continuous fiber-reinforced thermoplastic plastic rods 8 cut to a predetermined length are stacked on a stacker 12, passed through an oven 13 in a state of being stacked on a stacker 12, 14 and is then subjected to post-processing by the cooler 15 and the drilling machine 16. Thereafter, the back beam 20 of the finished product, which has been finally formed in the rack 17, .

그런데, 종래의 제조방법에서 연속섬유 강화 열가소성 플라스틱 테이프(5)가 연속섬유 강화 열가소성 플라스틱 로드(8)로 제작될 때에 단면이 원형인 원봉 형태의 로드(8)로 제작되고, 이후에 커팅기(11)로 일정 길이로 절단된 다수개의 원봉 형상 연속섬유 강화 열가소성 플라스틱 로드(8)를 스태커(12)에 적재 배열할 때에는 절단된 다수개의 로드(8)가 인접한 로드끼리 서로 선접촉을 하게 되는 바, 상기와 같이 선접촉된 상태로 오븐(13)을 통과하게 되면, 인접한 로드(8)끼리의 접합력에 산포가 발생하게 되고, 접합력에 산포 발생시 이후 프레스 금형(14)의 가공 후 제작 완료된 백빔(20)은 물성치에 변화가 생기게 됨으로써 불량품이 양산되는 단점이 있다.However, in the conventional manufacturing method, when the continuous fiber-reinforced thermoplastic plastic tape 5 is made of a continuous fiber-reinforced thermoplastic plastic rod 8, it is made of a rod 8 in the form of a circular rod having a circular section, Shaped continuous fiber-reinforced thermoplastic plastic rod 8 cut into a predetermined length by a predetermined length, the adjacent rods 8 are in line contact with each other when a plurality of rods 8 are cut and stacked on the stacker 12, When passing through the oven 13 in the state of line contact as described above, scattering occurs in the bonding force between the adjacent rods 8, and when the scattering occurs, the back beam 20 ) Has a disadvantage in that a defective product is mass-produced due to a change in the property value.

이하에서는 첨부된 도면을 참조하여 본 발명의 바람직한 실시 예에 따른 차량용 범퍼 백빔의 제조방법에 대해 살펴보기로 하겠는 바, 도 1의 종래 방법과 동일한 과정에 대해서는 동일한 도면 부호를 붙이면서 설명하기로 한다.Hereinafter, a method of manufacturing a bumper back beam for a vehicle according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The same steps as those of the conventional method of FIG. 1 will be described with the same reference numerals.

본 발명에 따라 연속섬유 열가소성수지(CFT)를 이용해서 차량용 범퍼 백빔을 제조하는 방법은 도 1을 참조로 전술한 바와 같이, 다수의 보빈(1)에 감겨진 유리섬유 강화플라스틱(2, FRP; fiber glass reinforced plastic)을 인발하여 합성수지(3)가 용융되어 있는 함침조(4)에 통과시켜서 연속섬유 강화 열가소성 플라스틱 테이프(5)를 제작한다.A method for manufacturing a vehicle bumper back beam using a continuous fiber thermoplastic resin (CFT) according to the present invention is a method for manufacturing a bumper backbone for a vehicle using a glass fiber reinforced plastic (2, FRP) wound around a plurality of bobbins (1) as described above with reference to Fig. fiber glass reinforced plastic is pulled out and passed through the impregnation tank 4 in which the synthetic resin 3 is melted to produce a continuous fiber reinforced thermoplastic plastic tape 5. [

그리고, 상기 연속섬유 강화 열가소성 플라스틱 테이프(5)를 히팅기(6)와 성형기(7)로 통과시켜서 도 2 및 도 3과 같은 연속섬유 강화 열가소성 플라스틱 로드(30,40)로 제작한다.The continuous fiber-reinforced thermoplastic plastic tape 5 is passed through a heater 6 and a molding machine 7 to produce continuous fiber-reinforced thermoplastic plastic rods 30 and 40 as shown in Figs. 2 and 3.

이때, 성형기(7)에 의해 제작된 연속섬유 강화 열가소성 플라스틱 로드(30,40)는 로드(30,40)의 길이방향을 따라 적어도 2개 이상이 평면을 구비한 모양으로 제작되는 바, 도 2와 같은 일 실시예에 따라 상기 연속섬유 강화 열가소성 플라스틱 로드(20)는 길이방향을 따라 적어도 2개 이상이 평면을 구비한 ㄴ자 단면모양으로 제작되거나 또는 도 2와 같은 다른 실시예에 따라 상기 연속섬유 강화 열가소성 플라스틱 로드(30)는 길이방향을 따라 적어도 2개 이상이 평면을 구비한 ㅁ자 단면모양으로 제작될 수 있다.At this time, the continuous fiber-reinforced thermoplastic plastic rods 30 and 40 manufactured by the molding machine 7 are manufactured in such a shape that at least two planes are provided along the longitudinal direction of the rods 30 and 40, The continuous fiber-reinforced thermoplastic plastic rod 20 may be formed in a shape of a cross-section having at least two planes along the longitudinal direction according to an embodiment such as FIG. 2, The reinforced thermoplastic plastic rod 30 may be formed in a cross-sectional shape having at least two planes along the longitudinal direction.

상기와 같이 ㄴ자 단면모양이나 또는 ㅁ자 단면모양으로 제작된 연속섬유 강화 열가소성 플라스틱 로드(30,40)는 냉각기(9)와 인취기(10)를 순차적으로 통과한 후 컷팅기(11)를 이용해서 백빔의 길이에 맞도록 일정 길이로 절단된다.The continuous fiber-reinforced thermoplastic plastic rods 30 and 40, which are manufactured in the form of a cross-sectional shape or a cross-sectional shape as described above, sequentially pass the cooler 9 and the drawer 10, As shown in FIG.

그리고, 일정 길이로 절단된 다수개의 연속섬유 강화 열가소성 플라스틱 로드(30,40)는 스태커(12; stacker)에 적재 배열되는 바, 이때 ㄴ자 단면모양으로 제작된 연속섬유 강화 열가소성 플라스틱 로드(30)는 상기 스태커(12)에 적재시 2개의 로드끼리 ㅁ자 단면모양을 이루도록 포개어져서 면접촉을 이루도록 적재되고, ㅁ자 단면모양으로 제작된 연속섬유 강화 열가소성 플라스틱 로드(40)는 상기 스태커(13)에 적재시 인접한 로드끼리 면접촉을 이루도록 적재된다.A plurality of continuous fiber-reinforced thermoplastic plastic rods 30 and 40 cut into a predetermined length are arranged on a stacker 12. The continuous fiber-reinforced thermoplastic plastic rod 30, The continuous fiber-reinforced thermoplastic plastic rod 40, which is formed to have a cross-sectional shape, is stacked on the stacker 12 so as to form a cross-sectional shape between the two rods when the stack is loaded on the stacker 12, And the adjacent rods are stacked so as to make a surface contact with each other.

따라서, 종래와 같이 연속섬유 강화 열가소성 플라스틱 로드(8)가 원봉 형상으로 제작되고, 원봉 형상의 연속섬유 강화 열가소성 플라스틱 로드가 스태커에 적재시 인접한 로드끼리 선접촉을 이루도록 적재된 상태일 때보다, 본 발명에 따른 실시예는 인접한 로드(20,30)끼리 면접촉을 이룸에 따라 접촉면적을 크게 확보할 수 있게 된다.Therefore, when the continuous fiber-reinforced thermoplastic plastic rod 8 is formed in the shape of a bar and the continuous fiber-reinforced thermoplastic plastic rod in the shape of a bar is stacked such that adjacent rods are in line contact with each other when the stack is loaded on the stacker, According to the embodiment of the present invention, since the adjacent rods 20 and 30 are in surface contact with each other, a large contact area can be secured.

상기와 같이 다수개의 연속섬유 강화 열가소성 플라스틱 로드(30,40)가 인접한 로드끼리 면접촉을 이루도록 스태커(12)에 적재된 상태에서 오븐(13)을 통과하게 되는 바, 이로 인해 오븐(13)을 통과한 연속섬유 강화 열가소성 플라스틱 로드(30,40)는 면접촉 된 로드끼리의 결합력에 산포가 발생하지 않거나 종래보다 크게 줄일 수 있게 된다.The plurality of continuous fiber-reinforced thermoplastic plastic rods 30 and 40 are passed through the oven 13 while being stacked on the stacker 12 so that the adjacent rods are in surface contact with each other, The passed continuous fiber-reinforced thermoplastic plastic rods 30 and 40 can be prevented from scattering or greatly reducing the bonding force between the surfaces-contacted rods.

오븐(13)을 통과하고 난 후에는 프레스 금형(14)을 이용해서 백빔의 형상으로 제작하게 되는 바, 이때 결합력에 산포가 발생하지 않도록 면접촉 된 연속섬유 강화 열가소성 플라스틱 로드(30,40)를 프레스 금형(14)을 이용해서 가공하게 되면, 제작 완료된 백빔은 물성치에 변화가 발생되지 않게 되며, 이 결과 불량품을 크게 줄일 수 있게 된다.After passing through the oven 13, the press mold 14 is used to form a back beam. At this time, the continuous fiber reinforced thermoplastic plastic rods 30 and 40 which are surface-contacted to prevent scattering When the press die 14 is used, the material properties of the manufactured back beam are not changed, and as a result, defective products can be greatly reduced.

프레스 금형(14)을 이용한 가공 후에는 냉각기(15)와 드릴링머신(16)으로 후 가공을 한 다음, 최종적으로 랙(17)에 형상 제작이 완료된 완제품의 백빔을 적재하게 된다.After the processing using the press mold 14, the post-processing is performed by the cooler 15 and the drilling machine 16, and finally the back beam of the finished product is loaded on the rack 17.

또한, 본 발명은 전술한 제조방법으로 제작된 차량용 범퍼 백빔을 특징으로 하는 바, 이를 통해 완제품의 백빔은 물성치에 변화가 발생되지 않은 양질의 백빔이 된다.
Further, the present invention is characterized by a bumper backbone for a vehicle manufactured by the above-described manufacturing method, whereby a back beam of the finished product becomes a high quality back beam without a change in physical properties.
