본 발명은 스틸관체 벤딩을 위한 다축 벤딩기에 관한 것으로서, 더욱 상세하게는 자동차의 트렁크리드와 연결된 행거아암 등 각종 용도의 스틸관체를 벤딩할 때 모형체가 다축에 의해서 움직이면서 스틸관체를 모형체의 외주면과 같은 형상으로 벤딩할 수 있도록 구성된 스틸관체 벤딩을 위한 다축 벤딩기에 관한 것이다.The present invention relates to a multi-axis bending machine for bending steel pipe, and more particularly, when bending a steel pipe for various uses such as a hanger arm connected to a trunk lid of an automobile, the steel body moves by the multi-axis while the steel pipe is moved with the outer peripheral surface of the model body. The present invention relates to a multi-axis bending machine for bending steel pipes configured to bend in the same shape.

주지하는 바와 같이 자동차의 트렁크리드와 연결된 행거아암이나 기타 각종 기계 기구를 구성하는 스틸관체로 된 부품들은 직선형태의 스틸관체를 벤딩기를 사용하여 소정의 형상으로 벤딩하여 사용하고 있다.As is well known, parts made of steel tubes constituting a hanger arm or other various mechanical mechanisms connected to a trunk lid of an automobile are used by bending a steel tube of a linear shape into a predetermined shape using a bending machine.

종래 상기한 바와 같이 직선형태의 스틸관체를 벤딩하기 위한 베딩기는 여러종류가 있으나 상기한 벤딩기의 대부분은 변곡점이 형성되어 있는 모형체가 고정되어 있고, 롤러가 모형체의 외주연을 따라서 이동하면서 스틸관체를 소정의 형상으로 벤딩하도록 구성되어 있다.As described above, there are many types of bedding machines for bending a straight steel tube, but most of the bending machines are fixed with a model body having an inflection point formed thereon, and the roller moves along the outer circumference of the model body. Is configured to bend to a predetermined shape.

이러한 구성으로 된 벤딩기는 스틸관체의 벤딩 지름(R)이 변경되면 그 조건에 맞춰서 원하는 모형체와 스틸관체의 외형과 같은 홈을 가진 구동롤러를 교환해 서 작업을 해야 하는 단점이 있다.The bending machine having such a configuration has a disadvantage in that when the bending diameter (R) of the steel tube is changed, the working model needs to be replaced by changing a driving roller having a groove such as the shape of the steel tube and the desired model body according to the condition.

또한, 구동롤러가 모형체의 외주연을 따라서 이동하면서 스틸관체를 소정의 형상으로 벤딩하는 경우에는 스틸관체가 벤딩되면서 벤딩방향으로 함몰되는 현상을 방지하기 위한 멘드럴을 사용하는 것이 원활하지 못한 단점이 있다.In addition, when the driving roller moves along the outer circumference of the model body and bends the steel tube into a predetermined shape, it is not smooth to use a mandrel to prevent the steel tube from bending and sinking in the bending direction. There is this.

도면의 미설명부호 50은 스틸관체, 51은 자동차용 트렁크리드 행거아암, 52는 맨드럴 지지대를 표시한 것이다.In the drawings, reference numeral 50 denotes a steel tube, 51 denotes a trunk lid hanger arm for an automobile, and 52 denotes a mandrel support.

이상과 같이 구성된 본 발명의 스틸관체 벤딩을 위한 다축 벤딩기에 관한 작용을 상세하게 설명하면 다음과 같다. Referring to the operation of the multi-axis bending machine for bending the steel tube of the present invention configured as described above in detail as follows.

본 발명에 의한 스틸관체 벤딩을 위한 다축 벤딩기로 스틸관체(50)를 소정의 형상으로 벤딩함에 있어서, 자동차용 트렁크리드 행거아암(51)을 실시예로 설명한다.When bending the steel tube 50 to a predetermined shape with the multi-axis bending machine for bending the steel tube according to the present invention, an automotive trunk lid hanger arm 51 will be described as an embodiment.

우선, 벤딩 구동부(2)를 구성하는 회전판(4)에 자동차용 트렁크리드 행거아암(51)의 절곡형상과 같은 외형을 갖는 모형체(5)를 고정한다.First, the model body 5 which has an external shape similar to the bending shape of the trunk lid hanger arm 51 for automobiles is fixed to the rotating plate 4 which comprises the bending drive part 2. As shown in FIG.

그리고, 스틸관체(50)를 맨드럴 지지대(52)위에 올려놓고 선단부를 클램프(6)에 고정시킨다.Then, the steel tube 50 is placed on the mandrel support 52 and the tip end is fixed to the clamp 6.

상기한 상태에서 피스톤(8)을 전진시켜서 그 선단에 설치된 맨드럴(7)을 스틸관체(50)에 삽입하는데 벤딩할 지점(받침롤러)까지 삽입하고 실린더(11) 및 로드(12)를 작동시켜 가압구(10)로 스틸관체(50)를 눌러준다.In the above state, the piston (8) is advanced to insert the mandrel (7) installed at the tip of the steel tube (50) to the point to bend (the supporting roller) and operate the cylinder (11) and the rod (12). Press the steel tube (50) by the pressure port (10).

이러한 상태에서 구동모터가 구비된 다축(3)에 의해서 각각 다른 각도로 회전판(3)이 회전을 하게 되면 도 2~7에서 보는 바와 같이 스틸관체(50)가 벤딩되는 것이다.In this state, when the rotary plate 3 rotates at different angles by the multi-axis 3 provided with the driving motor, the steel tube 50 is bent as shown in FIGS. 2 to 7.
