)이 항상 일정하다.Where the spacing of the holes 2a and 2b of the workpiece 2 (

) Varies depending on the size and specification of the block band, but is usually about 1-10 mm, and in one block band, the spacing (2a) and (2b) of each material (2)

) Is always constant.

)조절과 2차 가공시 중심을 잡기위해 약간만 뚫어 주는 것이고, 2차 가공시 1차 가공된 구멍(2a)(2b)을 더욱 깊이 뚫어 소재(2)와 연결구(3)의 돌기(3a)(3b)에 핀(4)이 삽입될 수 있게 하기 위한 것임을 알 수 있다. 그런데 상기와 같은 1차 드릴링 가공을 함에 있어 종래에는 작업자가 낱개로 된 소재(2)를 세워서 일일히 그 양측면에 에어드릴이나 전기드릴등으로 구멍(2a)(2b)을 뚫었던 것이다.As can be seen from the above manufacturing process, the primary processing of the raw material 2 is performed by the interval between the holes 2a and 2b (

Only slightly drilled to adjust the center of gravity and the secondary processing, and drills the holes (2a) and (2b) of the primary processing during the secondary processing to further deepen the projections (3a) of the material (2) and the connector (3) ( It can be seen that the pin 4 can be inserted into 3b). By the way, in the primary drilling process as described above, in the prior art, the worker erected a single piece of material 2 and drilled holes 2a and 2b with air drills or electric drills on both sides thereof.

)이 일정치 않고 인접한 소재와의 간격도 부정화하게 되어 밴드자체의 뒤틀림 현상이나 틈새 발생으로 불량율이 많게됨으로서 재료낭비와 생산성을 떨어뜨렸던 것이다. 또한 이러한 드릴링작업시는 통상 드릴에 가해지는 과부하를 방지하고 칩을 제거하기 위해구멍(2a)(2b)으로부터 몇차례의 삽,탈과정을 되풀이하게 되는데 이와 같은 삽, 탈과정중 구멍(2a)(2b)의 직경이 과다하게 커져 미관을 떨어뜨렸던 것이며, 아울러 구멍(2a)(2b)간의 간격(

)조절도 불량하여 공차가 누적됨으로서 밴드자체의 뒤틀림이나 일측방향으로만 장력을 받게되어 수명을 단축시키고, 록크장치의 이상을 초래하였던 것이다. 그리고 모든 작업이 수작업을 통하여 이루어짐으로서 불량율이 높고 생산성저하와 원가 및 인건비 상승등을 야기시켰던 것이다.Therefore, the manual operation in this way, the distance (α) between the holes (2a) (2b) and the position and depth are determined by the operator's sense, so no matter how skilled workers

), The gap between adjacent materials is negated, and the defect rate increases due to warpage or gap of the band itself, which reduces material waste and productivity. In addition, during such drilling operations, the insertion and removal processes are repeated several times from the holes 2a and 2b to prevent the overload applied to the drill and to remove chips. The diameter of (2b) was excessively large and the aesthetic appearance was dropped, and the gap between the holes (2a) and (2b)

) Tolerance is also poor, and the tolerance is accumulated, so that the band itself is warped or tensioned only in one direction, which shortens the life and causes the lock device to malfunction. And all the work was done by hand, which resulted in high defect rate, lower productivity, and higher labor and labor costs.
