상기 각각의 장치들로부터 소재(1) 또는 반제품(2)은 피더가 이송시키는데, 이는 일반적인 구조 및 구성이므로 상술하지 않기로 한다.The feeder 1 or semi-finished product 2 from each of these devices is conveyed by a feeder, which will not be described in detail as it is a general structure and configuration.

이와 같은 구성 및 구조를 가진 본 발명은 도 1과 도 2에 도시된 전체적인 구성을 가진다.The present invention having such a configuration and structure has the overall configuration shown in Figs.

우선 컷팅장치(50)에서 도 3과 도 4에 도시된 바와 같은 상형(14)과 하형(15)에 의하여, 소재(1)는 결합돌기(11)와 결합구멍(12) 및 외형과 각인 등이 형성된다. 그리고 일정거리 이동되어 다시 컷팅 등이 행하여져 도 5와 같은 반제품(2)이 성형된다. 반제품(2)에는 결합돌기(11)와 결합구멍(12)이 형성되고 일정 부분은 절곡되어 클램핑 작업 때 직경을 줄이는 데 사용되는 구조를 가지게 된다.First, by the upper mold 14 and the lower mold 15 as shown in FIGS. 3 and 4 in the cutting device 50, the material 1 is combined with the projection 11 and the coupling hole 12 and the outer shape and stamping, etc. Is formed. Then, the substrate is moved by a certain distance, and cutting is performed again to form the semifinished product 2 as shown in FIG. In the semi-finished product 2, the engaging projection 11 and the engaging hole 12 is formed and a certain portion is bent to have a structure used to reduce the diameter during the clamping operation.

컷팅장치(50)에 의해 반제품(2)이 성형되면, 피더가 이를 이송하여 1차벤딩장치(60)로 옮겨진다.When the semi-finished product 2 is molded by the cutting device 50, the feeder transfers it to the primary bending device 60.

1차벤딩장치(60)에서는 반제품(2)의 양측부를 벤딩하게 된다. 즉, 이송된 반제품(2)은 지그(3)에 의해 고정되고, 반제품(2)이 상측에는 벤딩시 반제품(2)을 지지하고 모양을 가지도록 하는 지지금형(4)이 위치하게 된다. 즉 지지금형(4)은 반 제품(2)의 양측부의 곡률로 볼록한 형상을 거지고, 이곳에 반제품(2)이 단부원호벤딩금형(5)과 끝단벤딩금형(6)에 의해 원호의 형상으로 벤딩된다.In the primary bending device 60, both sides of the semi-finished product 2 are bent. That is, the conveyed semifinished product 2 is fixed by the jig 3, and the semi-finished product 4 is positioned above the semifinished product 2 so as to support the semifinished product 2 when bending. In other words, the support now (4) has a convex shape with the curvature of both sides of the semi-finished product 2, where the semi-finished product (2) is in the shape of an arc by the end circular bending mold (5) and the end bending mold (6) Bend.

반제품(2)이 지그(3)에 고정되고, 지지금형(4)이 반제품(2)의 상부에 밀착되면, 하측에 설치된 한쌍의 단부원호벤딩금형(5)이 경사지게 상승하면서 반제품(2)의 양단부를 각각 상부로 벤딩시키게 된다. 물론 단부원호벤딩금형(5)은 상기 지지금형(4)과 체결되는 형상으로 되어 있고, 원호형의 오목한 형상이다.When the semifinished product 2 is fixed to the jig 3 and the jigs 4 are in close contact with the upper part of the semifinished product 2, a pair of end circular arc bending molds 5 installed on the lower side of the semifinished product 2 are inclined upwardly. Both ends are bent upwards, respectively. Of course, the end arc bending mold 5 has a shape that is engaged with the support ring 4, and is an arc-shaped concave shape.

단부원호벤딩금형(5)으로 양측이 벤딩되면, 벤딩부가 둥근 원의 4분의 1(1/4)보다 큰 경우는 다른 금형으로 끝단부를 다시 벤딩하여야 한다. 본 발명에서는 반제품의 일측단부는 1/4 원호보다 크고, 다른 단부는 1/4 원호보다 같거나 작다. 따라서 1/4 원호보다 큰 쪽에는 끝단벤딩금형(6)으로 다시 벤딩을 행하게 된다. 끝단벤딩금형(6)은 일측의 단부원호벤딩금형(5)에 회동되게 설치되어, 단부원호벤딩금형(5)의 작동이 끝난 후에 돌출된 반제품(2)의 단부를 벤딩시키는 구조이다. 이와 같이 반제품(2)의 양측을 벤딩시키는 구조가 도 6에 도시되어 있다.When both sides are bent with the end circular bending die (5), if the bending portion is larger than one quarter (1/4) of the round circle, the end portion should be bent again with another mold. In the present invention, one side end of the semi-finished product is larger than 1/4 arc, and the other end is the same or smaller than 1/4 arc. Therefore, bending is performed again to the end bending mold 6 at the larger side than the 1/4 circular arc. The end bending mold 6 is rotatably installed at one end circular arc bending mold 5, and is configured to bend the end of the semi-finished product 2 protruding after the end circular bending mold 5 is finished. Thus, the structure of bending both sides of the semifinished product 2 is shown in FIG.

1차 벤딩된 반제품(2)은 피더에 의해 2차벤딩장치(70)로 이송된다. 2차 벤딩은 반제품(2)의 가운데 부분을 벤딩시켜 고리형상의 완제품으로 형성시키는 것이다. 이송된 반제품(2)은 등근 지지환봉(7)에 밀착되고, 밀착된 반제품(2)은 승강하는 고정핀(8)에 의해 견고히 고정된다. 고정핀(8)은 반제품(2)을 지지환봉(7)에 밀착 고정시키고, 완제품으로 성형되면 이를 해제하는 것으로, 상하 승강하는 구조이다.The primary bent semifinished product 2 is transferred to the secondary bending device 70 by a feeder. Secondary bending is to bend the middle part of the semi-finished product 2 to form an annular finished product. The transported semifinished product 2 is in close contact with the back support round rod 7, and the semifinished product 2 in close contact is firmly fixed by the fixing pin 8 that moves up and down. Fixing pin (8) is fixed to the semi-finished product (2) in close contact with the support bar (7), and when it is molded into a finished product to release it, it is a structure to move up and down.

도 7과 같이, 반제품(2)이 지지환봉(7)의 하부로 이송되면, 고정핀(8)이 상 승하여 고정시키고, 양측에 설치된 하부링형벤딩금형(9)이 상승하여 좌우측을 벤딩시키게 된다. 따라서 반제품(2)은 지지환봉(7)과 이에 결합되는 한쌍의 하부링형벤딩금형(9)에 의해 둥근 원호의 형상을 가진 곡률로 벤딩된다.As shown in Figure 7, when the semi-finished product (2) is transferred to the lower portion of the support ring (7), the fixing pin (8) is raised and fixed, the lower ring-type bending mold (9) installed on both sides is raised to bend the left and right sides. do. Therefore, the semi-finished product 2 is bent in a curvature having a circular arc shape by the support ring 7 and a pair of lower ring-shaped bending molds 9 coupled thereto.

다음은 도 8과 같이, 한쌍의 상부링형벤딩금형(10)이 하강하면서 반제품(2)을 상측에서 벤딩하여 완전한 고리형상으로 성형시키게 된다. 이러한 공정 후에는 결합돌기(11)가 결합구멍(12)에 삽입된 상태가 된다.Next, as shown in Figure 8, the pair of upper ring-shaped bending mold 10 is lowered while bending the semi-finished product (2) from the upper side to form a complete ring shape. After this process, the engaging projection 11 is inserted into the engaging hole 12.

그리고 결합금형(13)이 하강하여 결합돌기(11)를 절곡시키게 되는데, 이의 작동으로 도 9와 같은 완전한 고리형상이 유지된 클램프(100)가 완성된다.And the coupling mold 13 is lowered to bend the coupling protrusion 11, the operation of which completes the clamp 100 is maintained in a complete ring shape as shown in FIG.

이와 같이 본 발명은 호스 클램프(100)가 컷팅 후 2차에 걸친 벤딩 작용으로 완성되고, 모든 과정이 자동화된 생산이 가능하여, 생산성이 향상됨은 물론이고, 품질이 균일하게 이루어지며, 특히 2차에 걸친 벤딩으로 인하여 정확한 직경을 가진 클램프로 제조됨으로써, 호스와 파이프 등의 결합시 사용되는 클램프가 사이즈별로 정확하게 삽입되어 사용될 수 있는 편의성을 제공하게 된다.As described above, the present invention is completed by the bending action of the hose clamp 100 after the second cut, and all processes can be automated production, as well as the productivity is improved, the quality is made uniform, especially secondary Due to the bending over, it is manufactured with a clamp having the correct diameter, thereby providing a convenience that the clamp used when the hose and the pipe are combined can be inserted and used correctly by size.
