Deflection-load resistance control method for multi-station press

The invention discloses a deflection-load resistance control method for a multi-station press. The deflection-load resistance control method is characterized in that the ratio of the punching nominalforce borne by the inlet side to the punching nominal force borne by the outlet side of the multi-station press is controlled to be 3 to 2, and then the pressure of balancers located on the inlet sideand the outlet side are controlled, so that the gravity center of a sliding block is located on the geometric center of the multi-station press; and finally, the unloading ratio of an overload protective value in an overload protective device on the inlet side is controlled to be 1 to 1.9, the unloading ratio of an overload protective value in an overload protective device on the outlet side is controlled to be 1 to 2.4, and the ratio of products of the unloading oil pressure and the areas of oil pressure chambers in the overload protective devices on the inlet side and the outlet side is 3 to 2.
