|
The synchronism of double-point driving press is the main reason that affects the press′s precision,also the phase deviation of the crank angle,the radius deviation of the crank and the length deviation of the connecting rod affect the press′s synchronism severely.The mathematical calculation was used to deduce the calculating formula of the slide-displacement deviation caused by the main deviations mentioned above and the max value of the slide-displacement.The calculating results were analyzed.Thus the results provide the theoretical basis for adjusting the synchronism of the double-point driving press.
