본 고안은 각각 스프링에 의하여 탄력 지지되는 지지틀과 이동체상에 사각관체를 위치시킨뒤 상부금형을 하강시키면서 지지틀이 하강하면서 사각관체가 이동체의 지지로울러와 상부금형에 의해 정확하게 절곡되도록 한 톱고정대용 사각관체의 절곡장치에 관한 것이다.The present invention places the square tube on the support frame and the movable body elastically supported by the spring, respectively, and then lowers the upper mold while the support frame is lowered, so that the square tube is accurately bent by the support roller and the upper mold of the movable body. It relates to a bending device for surrogate square tubes.

종래에는 이러한 절곡장치가 없어 일일이 사람의 손으로 절곡작업을 하였기 때문에 생산성이 낮고 절곡이 동일한 형태의 제품을 대량으로 제작하기가 곤란한 등의 문제점이 있는 것이었다.Conventionally, since there is no such a bending device, because the bending work is performed by human hands, there is a problem that it is difficult to produce a large amount of products having low productivity and the same type of bending.

본 고안은 이러한 문제점을 해결하기 위하여 안출한 것으로 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a problem and will be described in detail with reference to the accompanying drawings.

통상의 프레스기 받침틀(2)상에 밑판(2)을 볼트로 고정하고 밑판(2) 위에 두개의 지지편(3)(3')을 일정간격 대향되게 세워 볼트(4)로 고정하고 지지편(3)(3')의 내측에 안내편(5)(5')을 세워 볼트(6)로 고정하고 밑판(2)에 나사식으로 결합된 고정봉(7)에 스프링(8)을 끼워 스프링(8)의 하단이 고정봉(7) 하단에 볼트(9)로 고정된 고정편(10)에 걸리고 스프링(8)의 상단은 고정봉(7)에 승강가능하도록 끼워진 승강편(11)에 걸리도록 하여 승강편(11)이 항상 스프링(8)의 탄발력에 의하여 상향으로 탄력지지되게 하고 밑판(2)의 관통공(12)(12')에 승강가능하도록 끼워진 받침봉(13)(13')의 상단을 지지틀(14)의 저면에 형성된 고정공에 끼워 고정되게 하므로서 지지틀(14)이 하강하면 받침봉(13)(13')에 의하여 승강편(11)이 하강토록 하고 지지틀(14)의 일측면에는 원호상의 요입면(15)을 형성하고 상면에는 바닥이 요입면(15) 쪽으로 약간 경사진 요홈(16)을 형성하였으며 지지틀(14)의 타측면은 수직으로 형성되어 지지틀(14)이 승강할 때 이 수직의 측면이 안내편(5)(5')의 측면과 접하여 안내되도록 하고 안내편(5)(5')의 타측면에 나사식으로 결합된 지지봉(17)(17')의 단부에 조정편(18)을 이동가능하도록 끼워 너트(19)로 고정하므로서 사각관체(20)의 길이에 따라 조정편(18)이 적절히 이동되게 하였다.Fix the bottom plate 2 with bolts on the press presser frame 2, and fix the two support pieces 3, 3 'on the bottom plate 2 with a bolt 4 so as to face each other at regular intervals. 3) Set the guide pieces 5, 5 'inside the 3' and fix them with bolts 6, and insert the spring 8 into the fixing rod 7 screwed to the base plate 2. The lower end of the (8) is caught by the fixing piece (10) fixed by the bolt (9) to the lower end of the fixing rod (7) and the upper end of the spring (8) to the lifting piece (11) fitted to be able to lift and lower the fixing rod (7) A supporting rod 13 (13) which is fitted so that the elevating piece 11 is always elastically supported upward by the spring force of the spring 8 and is movable up and down in the through holes 12 and 12 'of the base plate 2 ( 13 ') is inserted into a fixing hole formed on the bottom of the support frame 14, and the support frame 14 is lowered so that the lifting piece 11 is lowered by the supporting rods 13 and 13'. On one side of the support frame 14 is an arc-shaped recessed surface 15 The upper surface is formed with a groove 16 in which the bottom is slightly inclined toward the indentation surface 15. The other side of the support frame 14 is formed vertically so that the vertical side is guided when the support frame 14 is elevated. The adjustment piece 18 is provided at the end of the supporting rods 17 and 17 'which are guided in contact with the side surfaces of the pieces 5 and 5' and screwed to the other side of the guide pieces 5 and 5 '. The fitting piece 18 was properly moved according to the length of the square tube 20 by being fitted to be movable to fix the nut 19.

지지틀(14)과 약간의 사이를 두고 지지편(3)(3') 사이에서 좌우로 이동운동하는 이동체(21)를 위치시키고 이동체(21) 상부에는 지지틀(14)의 요홈(16)과 간격이 일치하는 요홈(23)이 형성된 지지롤러(24)를 설치하되 "제2도"에서와 같이 지지롤러(24)와 지지틀(14)의 요입면(15) 사이에 약간의 간격이 있도록 하였다.Position the movable body 21 to move left and right between the supporting frame 14 and the support piece 3, 3 ′ between the supporting frame 14 and the recesses 16, and the recess 16 of the supporting frame 14 is located above the movable body 21. Install a supporting roller 24 having a groove 23 coinciding with the space between the supporting rollers 24 and the recessed surface 15 of the support frame 14 as shown in FIG. It was made.

지지편(3)(3') 사이에 이동체(21)와 일정간격을 두고 고정체(25)를 볼트(26)로 고정하고 고정체(25)에 뚫려 있는 안내공(27)에 안내봉(28)을 이동가능하도록 끼우고 안내봉(28)의 일측은 이동체(21)에 용접하고 타측은 스프링(29)에 의하여 내측으로 탄력지지되는 이동판(30)에 용접하였으며 프레스의 승강봉(31) 하단에 원하는 정도의 만곡면(32)이 형성된 상부금형(33)을 부착하여서 된 것이다.The fixed rod 25 is fixed with the bolt 26 at a predetermined interval between the support pieces 3 and 3 'and guide rods are formed in the guide holes 27 drilled through the fixed bodies 25. 28) to be movable and one side of the guide rod 28 is welded to the moving body 21 and the other side to the movable plate 30 which is elastically supported inward by the spring 29 and the lifting bar of the press (31) At the bottom is to attach the upper mold 33 is formed a curved surface 32 of the desired degree.

미설명 부호(34)는 스프링 고정편, (35)는 스프링 고정편을 관통하여 이동하는 이동봉이다.Reference numeral 34 is a spring fixing piece, 35 is a moving rod moving through the spring fixing piece.

이와 같은 구성된 본 고안은 절곡형성코자 하는 사각관체(20)를 제2도에서와 같이 지지틀(14)의 요홈(16)과 지지롤러(24)의 요홈(23)에 넣고 조정편(18)을 이동시켜 사각관체(20)가 고정체(25)와 조정편(18)에 의하여 적절히 지지되게한 다음 프레스를 작동시켜 상부금형(33)을 하강시키면 제3도와 같이 지지틀(14)이 하강하고 이동체(21)가 약간 뒤로 밀리면서 지지롤러(24)와 상부금형(33)의 만곡면(32)에 의하여 사각관체(20)가 원하는 형상으로 절곡된다.The present invention configured as described above puts the square tube 20 to be bent into the groove 16 of the support frame 14 and the groove 23 of the support roller 24 as shown in FIG. Move the square tube 20 so that it is properly supported by the fixture 25 and the adjusting piece 18, and then operate the press to lower the upper mold 33 so that the support frame 14 is lowered as shown in FIG. And the square body 20 is bent to a desired shape by the support roller 24 and the curved surface 32 of the upper mold 33 while the movable body 21 is pushed back slightly.

절곡이 완료되어 상부금형(33)이 상승하면 지지틀(16)과 이동체(21)도 각각 스프링(8)(29)의 반발력에 의하여 원래 위치로 복귀하여 다음 절곡작업을 대기하게 된다.When the bending is completed and the upper mold 33 is raised, the support frame 16 and the movable body 21 also return to their original positions by the repulsive force of the springs 8 and 29, respectively, waiting for the next bending operation.

따라서 본 고안은 상부금형(33)의 승강작용에 따라 간단하고 신속하게 절곡작업이 이루어직 상부금형(33)의 만곡편(32)과 하강정도에 따라 사각관체(20)가 정확하게 절곡되므로 절곡작업이 신속용이하여 생산성이 높고 동일한 형상으로 정확하게 절곡된 사각관체의 대량생산이 가능하게 되는 효과가 있는 것이다.Therefore, the present invention is a simple and quick bending work is made according to the lifting action of the upper mold 33, the bent work because the square tube 20 is precisely bent according to the bending piece 32 and the degree of falling of the upper mold 33 This rapid ease of use has the effect of enabling the mass production of a square tube that is highly productive and precisely bent into the same shape.
