发明名称 Cushion construction including snubber
摘要 A die cushion construction for use in a press is the subject matter of the present invention. The instant die cushion construction includes a fixed plate connected to the press. A resilient cushion actuator has one end sealingly connected to the fixed plate. The resilient cushion actuator has an opposite end sealingly connected to a movable plate. The movable plate is adapted for connection to a portion of a die mounted in the press. A resilient snubber actuator has one end fixed relative to the fixed plate. The snubber actuator has an opposite movable end connected to the movable plate for affecting the rate of movement of the movable plate and a portion of the die. The snubber actuator is connected to means for allowing fluid to flow into the snubber actuator when the movable plate moves toward the snubber actuator.
