Abstract
The utility model relates to a stroke-adjustable air cushion device of a pressing machine, belonging to the technical field of the pressing machine. The utility model relates to the improvement that an ejector rod of two gas cushions of the pressing machine are connected with a same air cushion top plates and are driven by a same driving mechanism, wherein a driving adjustment device is arranged on each air cushion and is arranged under a bed plate of the pressing machine; and the driving adjustment device consists of a servo motor, a transmission mechanism and a stroke adjustment mechanism; after the servo motor rotates, a big gear in the transmission mechanism can drive a thread bushing in the stroke adjustment mechanism and the ejector rod to rotate, so as to realize the stroke adjustment. The stroke-adjustable air cushion device can do the reciprocating motion up and down along with a sliding block and is the special part for expanding the process range of the pressing machine. The stroke-adjustable air cushion device has simple and reasonable structure, is beneficial for expanding the process range of the pressing machine and especially has strong practicability and obvious economic benefit for the stamping procedure with more stations.
