The invention provides a heavy bi-functional press movable beam balance control loop with returning and loading functions. The heavy bi-functional press movable beam balance control loop comprises an oil tank, a variable pump oil supply sub-loop, a left inlet oil control sub-loop, a right inlet oil control sub-loop, an upper balance cylinder unloading sub-loop, a lower balance cylinder unloading sub-loop, an upper balance cylinder and a lower balance cylinder which is arranged on the lower surface of a movable beam and arranged at the position in corner symmetrical with the upper balance cylinder. The variable pump oil supply sub-loop communicates with the upper balance cylinder and a lower adjusting cylinder through the left inlet oil control sub-loop, and the variable pump oil supply sub-loop communicates with the lower balance cylinder and an upper adjusting cylinder. The heavy bi-functional press movable beam balance control loop can carry out balance control over the movable beam and can carry out returning control or auxiliary loading on the movable beam when balance control is not carried out so that the technical problems that an existing heavy press movable beam balance loop only meets the low-speed movement requirement of the movable beam during die forging and cannot meet the high-speed requirement of the movable beam during perpendicular extruding, the function is singular, and the utilization rate is low can be solved.
