摘要:
A controllable force cushion device that can be programmed to provide a variable and/or pulsating force that can be used in any application where force control is desirable. The frequency of the pulsation can be adjusted to suit different applications and/or circumstances (e.g., forming of sheet metals in die applications, etc.). The cushion can comprise one or more manifolds containing hydraulic cylinders that can be compressed during operation pushing fluid through a proportional relief valve that can be controlled by a motion control device, thereby creating a desired force. Material (e.g., sheet metal, etc.) flow can be controlled by using a gap control method. In use, the variable pulsating, gap control, auto-learning press cushion device of the present invention can optionally be mounted to the underside of a press bolster and can be used in conjunction with a stamping press.
