Description

Technical Field

[0001] The utility model relates to the field of stamping equipment, in particular to a servo press. Background Art

[0002] Stamping equipment is a very common type of equipment. In the prior art, the power source of the stamping equipment is an ordinary motor, which drives the flywheel and the cam to move, and then drives the lifting and pressing head to lift and lower. When the lifting and pressing head descends, the product is stamped into shape. There are many disadvantages in this stamping equipment in the prior art. For example, the flywheel and the cam have low stability during movement and generate extremely high noise. For another example, when an ordinary motor is used as the power source, the speed of the motor cannot be adjusted arbitrarily according to the actual situation, so it is difficult to arbitrarily control the pressing speed, pressure, and pressing position of the lifting and pressing head.
