본 고안은 타이어용 고무튜브를 성형함에 있어서 압출기로부터 압출된 압출고무를 가류시키기전에 정확한 튜브형태가 형성되도록 성형하는 타이어튜브성형기의 개량에 관한 것이다.The present invention relates to an improvement of a tire tube molding machine for molding a rubber tube for a tire to form an accurate tube shape before vulcanizing the extruded rubber extruded from the extruder.

일반적으로 타이어용 튜브를 성형함에 있어서는 소정의 크기로 절단하여 원형링의 형태로 접착한 미완성 고무튜브를 공기가 취입되어 팽창된 상태의 직경과 거의 동일한 직경의 원형포머에 끼워 공기를 취입시킨 후 가류기에 넣어 가류시키므로서 튜브를 성형하고 있다.In general, in forming a tube for a tire, an unfinished rubber tube cut into a predetermined size and bonded in the form of a circular ring is blown into a circular former having a diameter almost the same as that of the expanded state by blowing air, followed by vulcanization. The tube is molded while being vulcanized.

그러나 종래의 성형기는 원형포머가 튜브의 직경과 동일한 크기로 되어 있으므로 전술한 바와같은 포밍작업시 튜브를 성형기의 포머에 착탈하는 작업이 매우 어렵고 착탈시 힘이 가해져 당겨지게 되므로 부분적으로 두께가 얇아지는 등 전체두께가 일정하지 않으며 절목현상이 발생되는 폐단이 있었다.However, in the conventional molding machine, since the circular former has the same size as the diameter of the tube, it is very difficult to attach or detach the tube to the former of the molding machine during the forming operation as described above, and when the detaching force is applied, a force is applied to the former, so that the thickness is partially thinned. The entire thickness of the back was not constant, and there was a discontinuity in which an anomaly occurred.

본 고안은 이와같은 점을 감안하여 안출한 것으로 포머를 4조각으로 분리하여 원형으로 조립하되 적은 직경으로 축소시켜 고무튜브의 착탈을 용이하게 한것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been made in view of the above points, and the former is separated into four pieces to assemble in a circular shape, but reduced to a smaller diameter to facilitate the detachment and detachment of the rubber tube.

받침대(1) 상단의 축관(2)에 반원형요입부(3)가 요설된 원형상의 포머(4)를 착설한 튜브성형기에 있어서 포머(4)를 상하좌우가 각각 서로 대칭되게 4조각(4')(4")(4'")(4"")으로 분리하되 상, 하부의 분리된 포머조각(4')(4")을 좌우의 분리된 포머조각(4'")(4"")보다 적은 크기로 구성하고 상, 하의 분리된 포머조각(4')(4")은 내측에 축수(5)를 일체로 부착하여 축관(2)의 선단에 수직으로 입설한 안내봉(6)에 이를따라 승강될 수 있도록 관삽하며 상, 하 포머조각(4')(4")의 축수(5) 양측에는 당김봉(7)(7')을 외향 경사지게 대칭으로 착설하여 이를 좌우의 포머조각(4'")(4"")의 내측에 일체로 부착한 플레이트(8)의 축공(9)에 유삽하는 한편 축관(5)의 내부에는 실린더(10)의 피스톤롯드(10')에 의해 좌우 진퇴작동하는 작동봉(11)을 끼워넣고 그 선단에 축관(5)의 안내공(12)을 따라 작동되는 브라켓트(13)를 착설하여 링크(14)를 매개로 상, 하의 포머조각(4')(4")의 축수(5)에 연결하여서 되는 것이다.In the tube forming machine in which the circular former 4 with the semicircular inlet 3 is provided on the shaft tube 2 of the upper part of the pedestal 1, the former 4, 4, 4 'is formed to be symmetric with each other. (4 ") (4 '") (4 ""), but separate upper and lower pieces of former (4') and 4 "from the left and right pieces of former (4 '") (4 "" The guide rod (6) vertically installed at the tip of the shaft pipe (2) with a smaller size and having upper and lower separated former pieces (4 ', 4 ") integrally attached with the bearing (5) inside. It is inserted into the pipe so as to move up and down, and the pull rods (7) and (7 ') are installed on both sides of the shaft (5) of the upper and lower former pieces (4', 4 ") to be inclined outwardly and symmetrically. The piston rod 10 'of the cylinder 10 is inserted into the shaft hole 9 of the plate 8 integrally attached to the inside of the (4' ") (4" "). Insert the actuating rod 11 to move left and right and move along the guide hole 12 of the shaft pipe 5 at its tip. The same bracket 13 is installed and connected to the shaft 5 of the upper and lower former pieces 4 'and 4 "via the link 14.

도면중 미설명부호 15는 포머회전용 모타이고 16은 체인이며 17은 체인기어이고 18은 고무튜브이다.In the drawings, reference numeral 15 denotes a motor for exclusive use of a former, 16 is a chain, 17 is a chain gear, and 18 is a rubber tube.

이와같이된 본 고안은 포머(4)를 4조각의 상하, 좌우로 대칭되는 포머조각(4')(4")(4)(4"")으로 분리하되 좌, 우의 포머조각(4)(4"")보다 적은 크기의 상, 하부의 포머조각(4')(4")의 내측에 일체로 부착된 축수(5)를 축관(2)의 선단에 수직으로 입설한 안내봉(6)에 이를따라 승강될 수 있도록 관삽하여 실린더(10)의 피스톤롯드(10')에 의해 좌우진퇴 작동하는 작동봉(11) 선단의 브라켓트(13)에 링크(14)를 매개로 연결하고 좌, 우의 분리된 포머조각(4'")(4"")은 상하부의 포머조각(4')(4")에 일체로 착설된 당김봉(7)(7')을 플레이트(8)의 축공(9)에 유삽하여 서로 연결하였으므로 실린더(10)의 피스톤롯드(10') 진퇴작동으로 이에 연결된 작동봉(11)이 축관(2)의 내부에서 좌우 작동하게 되면 작동봉(11)의 선단에 부착된 브라켓트(13)가 축관(2)의 안내봉(12)을 따라 활주하면서 링크(14)를 매개로 상, 하부의 분리된 포머(4')(4")에 축수(5)를 승강시키게 되므로 상, 하부의 분리된 포머조각(4')(4")은 상하로 승강자재되며 이와동시에 당김봉(7)(7')으로 연결된 좌우의 분리된 포머조각(4'")(4"")도 당김봉(7)(7')의 경사상의 이동에 따라 내측으로 동시에 수축되거나 신장되어진다.In this way, the present invention is a former piece (4 ') (4 ") (4") (4 ") that is symmetrical from left to right and up and down of four pieces. (4 ""), but the left and right former piece (4 A guide rod having a shaft 5 vertically attached to the distal end of the shaft pipe 2 integrally attached to the inside of the upper and lower former pieces 4 " 6) by connecting the link 14 to the bracket 13 at the tip of the operating rod 11, which is pushed forward and backward to move up and down by the piston rod 10 'of the cylinder 10 so as to be elevated accordingly. , The separated former piece (4 '") (4"") of the upper and lower pieces of puller rods (7) (7') mounted integrally with the former piece (4 ') (4") of the shaft of the plate (8) (9) is connected to each other by being inserted into the piston rod (10 ') of the cylinder 10, the operation rod 11 connected to it by the retracting operation in the shaft tube (2) left and right operation at the tip of the operating rod (11) An attached bracket 13 slides along the guide rod 12 of the shaft pipe 2 and lifts the bearing 5 onto the upper and lower separated formers 4 'and 4 "via the link 14. The upper and lower separated former pieces (4 ', 4 ") are lifted up and down The left and right separate former pieces (4 '", 4""), which are rigid and connected to the pull rods (7) and 7' at the same time, are also moved inward as the inclined movement of the pull rods (7) and (7 '). At the same time they contract or stretch.

따라서 타이어튜브(18)를 포머(4)에 끼워넣을 때에는 제4도 및 제5도와 같은 상태에서 실린더(10)를 작동시켜 피스톤롯드(10')를 인출시키면 작동봉(11)로 동시에 축관(2)의 밖으로 인출되므로 그 선단의 브라켓트(13)가 뒤로 후퇴하면서 링크(14)를 매개로 축수(5)를 당기게 되므로 축수(5)는 안내봉(6)을 따라 포머(4)의 중심을 향해 이동되어 직경을 축소시키게 되며 상, 하부의 포머(4)(4')가 중심을 향해 이동되면 좌, 우 분리된 포머(4'")(4"")의 플레이트(8)의 축공(9)에 유삽된 당김봉(7)(7')도 경사상으로 중심을 향해 이동되므로 좌, 우의 분리된 포머(4'")(4"")를 내측으로 당기게됨에 따라 좌우의 분리된 포머조각(4'")(4"")은 내측으로 동시에 이동되어 당겨지므로 포머(4)를 제3도와 같이 타원형의 형태로 축소시키므로서 타이어튜브(18)를 포머(4)에 끼워넣기가 매우 용이해지는 것이다.Accordingly, when the tire tube 18 is inserted into the former 4, the cylinder rod 10 is pulled out by pulling the piston rod 10 ′ in the state shown in FIGS. 4 and 5, and the shaft tube ( 2) is pulled out, so that the bracket 13 at its distal end retracts back and pulls the bearing 5 via the link 14, so that the bearing 5 moves along the guide rod 6 to the center of the former 4; When the upper and lower formers 4 and 4 'are moved toward the center, the shaft holes of the plate 8 of the former and left separated formers 4' "and 4" "are moved. Pulling rods 7 and 7 'inserted in 9) are also moved obliquely toward the center, and thus the left and right separated formers 4' "and 4" "are pulled inwards to separate the formers. Pieces 4 '", 4" "are simultaneously moved and pulled inward, so that the former 4 is reduced to an elliptical shape as shown in FIG. 3 so that the tire tube 18 can be inserted into the former 4 very much. for This is what happens.

그리고 타이어(18)를 포머(4)에 끼운 후에는 실린더(10)를 작동시켜 피스톤 롯드(10')를 몰입시키므로서 작동봉(11)을 축관(2)속으로 인입시키게 되면 브라켓트(13)가 축관(2)의 안내공(12)을 따라 이동되어 링크(14)를 매개로 축수(5)를 외측으로 밀어내게 되므로 이에 일체로 연결된 상, 하부의 분리된 포머조각(4)(4')이 신장됨에 따라 당김봉(7)(7')으로 연결된 좌, 우의 분리된 포머조각(4)(4"")도 당김봉(7)(7')의 밀어냄으로 인해 외측으로 벌어져 본래상태의 원형을 형성하게 되므로 타이어튜브(18)를 일정두께로 균일하게 성형할 수 있는 것이다.After the tire 18 is inserted into the former 4, the cylinder 10 is operated to immerse the piston rod 10 ′ while the operating rod 11 is introduced into the shaft tube 2. It moves along the guide hole 12 of the shaft tube 2 and pushes the shaft 5 outward through the link 14 so that the upper and lower separate pieces of formers 4 and 4 'are integrally connected thereto. As the elongation increases, the left and right separate former pieces (4) connected by the pulling rods (7) (7 ') (4 "") is also opened to the outside due to the push of the pull rod (7) (7 ') to form a circular shape of the original state, it is possible to uniformly mold the tire tube 18 to a certain thickness.

이와같이 본 고안은 포머(4)를 상하, 좌우로 분리하여 튜브(18)를 간단히 끼워넣을 수 있는 직경으로 축소시킬 수 있어 튜브(18)의 착탈이 매우 용이하고 이로인해 튜브(18)를 균일한 두께로 일정하게 성형할 수 있으며 절목형상의 발생을 방지할 수 있는 효과가 있다.In this way, the present invention can be reduced to a diameter that can be easily inserted by separating the former (4) up and down, left and right, it is very easy to attach and detach the tube 18, thereby making the tube 18 uniform It can be molded uniformly in thickness and has the effect of preventing the occurrence of cutting wood.
