With the servomotor for controlling torque as described above, both dies can be pressed with a required tightening force. However, the position for supplying and unloading the work to and from the movable mold is controlled by other means.If the work is a thin line or a thin plate, it is necessary to accurately determine the supply position, and torque control is required. It is extremely difficult to control the position of a servomotor for use. In order to obtain the accuracy of this supply position, a servo motor for position control may be used.However, when the movable mold is stopped at the position where the movable mold and the fixed mold match, the required tightening force can be obtained. There was no problem.
