目前市场上使用的用于冲压、拉伸和挤压生产的装置，比如用在液压薄板下料机处，均为电机驱动皮带轮、皮带轮带动齿轮旋转，齿轮带动曲柄机构运行的机械下料机，在其工作时，不仅冲击振动和冲击噪声大，而且功耗高。
发明人申请的专利号为ZL201120326594.7，发明名称为一种液压薄板下料机的一件中国专利，该装置采用的曲肘增力机构包括上肘杆、曲肘杆和短连杆，上肘杆下端铰接于曲肘杆拐角处，曲肘杆下端铰接于机座台板上平面的下支座上，曲肘增力机构短连杆的一端铰接于曲轴杆，另一端铰接于活动支架上，活动支架与液压油缸的活塞杆固定。但是，经过发明人多年使用，发现如下问题：1.现有用于冲压、拉伸和挤压生产的装置的传力不均匀；2.现有用于冲压、拉伸和挤压生产的装置整体结构受限，不能进行扩展；3、现有用于冲压、拉伸和挤压生产的装置的结构复杂。
