본 발명은 양측에 플라이휠이 구비된 프레스구조에 관한 것으로, 모터를 이용하여 편심축 양쪽에 플라이휠을 설치함으로서 편하중이나 소음 및 진동없이 안정적으로 작업할 수 있는 양측에 플라이휠이 구비된 고속프레스에 관한 것이다.The present invention relates to a press structure provided with flywheels on both sides, and to a high-speed press provided with flywheels on both sides that can stably work without bias or noise and vibration by installing flywheels on both sides of the eccentric shaft using a motor. .

현재 공작기계 중 프레스 기계는 모든 기간산업에 널리 사용되는 판금가공기계로서 중요한 기계이다. 선반, 밀링 등 일반 공작기계는 정밀, 첨단, NC화 되고 가고 있지만 프레스는 그렇지 못하다. 그러나 다른 공작기계와는 달리 프레스는 타발을 하는 기계로서 타발시 진동과 가공 소음이 발생하게 된다. 또한 프레스 가공의 동향이 단발 금형가공에서 순차적 가공인 프로그래시브(Progressive)가공으로 변환되면서 가공시 소음은 더욱 커진다. 그러므로 현재 프레스업계에서는 프로그래시브가공으로 생산성을 높이면서도 소음 및 진동을 획기적으로 줄일 수 있는 방안을 모색해야 하는 것이 중요한 과제이다.Currently, the press machine among the machine tools is an important machine as a sheet metal processing machine widely used in all industries. General machine tools such as lathes and milling are becoming precise, advanced and NC, but presses are not. However, unlike other machine tools, presses are punching machines, which generate vibration and processing noise when punched. In addition, as the trend of press processing is changed from single mold processing to progressive processing, which is a sequential processing, the noise during processing increases. Therefore, in the press industry, it is important to find ways to dramatically reduce noise and vibration while increasing productivity through progressive processing.

기계식 프레스장치는 한개의 플라이휠에 의해 모든 부하변동을 흡수하도록 디자인 된 기계이다. 프레스 작업에 의해 순간적으로 발생하는 과다하게 큰 부하변동을 큰 플라이휠의 관성력에 의해 흡수하도록 하는 것이 합리적이고 바람직하지만, 슬라이더에 왕복운동을 가할 때에 발생하는 일정한 부하변동은 저속시에는 무시할 수 있지만, 고속운전시에는 그 에너지가 프레스 작업의 에너지를 초과하게 되어, 플라이휠에 설치된 편심축의 회전속도가 증가함으로써, 편심축의 변동으로 프레스 기계는 매 회전시마다 불안정적 됨으로서, 매회전시마다 주기적으로 변화하게 한다. 이러한 입력구동계의 회전변동은 프레스의 진동과 소음을 초래하고, 또 클러치와 브레이크의 내구성에 악영향을 가하는 문제점이 있다.Mechanical presses are machines designed to absorb all load variations with a single flywheel. Although it is reasonable and desirable to absorb excessively large load fluctuations generated by press operation by the large flywheel inertia, constant load fluctuations generated when reciprocating the slider can be ignored at low speed, but During operation, the energy exceeds the energy of the press work, and the rotational speed of the eccentric shaft installed in the flywheel increases, so that the press machine becomes unstable at every rotation by the variation of the eccentric shaft, causing it to change periodically at every rotation. Such rotational variation of the input drive system causes vibration and noise of the press, and also adversely affects durability of the clutch and brake.

상술한 바와 같은 문제를 해결하기 위하여 본 발명에서는, 양측에 구비되는 플라이휠에 의해 프레스 구동시 안정감 있는 작업이 가능한 프레스를 제공하는 것을 목적으로 한다.In order to solve the problems as described above, an object of the present invention is to provide a press capable of stable operation during press driving by flywheels provided on both sides.
