The Electric Press Brake, which is directly driven by a servo motor and generates pressure through mechanical transmission, is collectively referred to as a Electric Press Brake. At present, there are two mature servo electric bending machines in the market: one is the servo motor driving the heavy-duty ball screw to drive the slider to reciprocating motion and drive the upper mold on the slider to apply force to the lower mold on the workbench, so that the metal sheet can be bent and formed into the required shape and size; One type is that the servo motor drives the belt and moving pulley group to drive the slider to perform reciprocating motion and drive the upper mold on the slider to apply force to the lower mold on the workbench, so as to bend the metal sheet into the required shape and size.
The following mainly explains the electric press brake driven by heavy-duty ball screw：
The servo electric bending machine is composed of servo motor, screw transmission device, body, slider, fixture mold, back guage, appearance, and control system. It is obvious that the servo electric bending machine eliminates the hydraulic system compared to traditional hydraulic bending machines, resulting in higher transmission efficiency and fewer factors affecting accuracy; It also reduces the waste oil generated by the hydraulic system, making it more environmentally friendly; The servo fully electric bending power output is a servo system, which adjusts the output power according to load changes during operation, which will be more energy-saving.
Comparison of power consumption of each step between a 40 ton fully electric press brake and a commonly used 40 ton hydraulic press brake
The larger the tonnage of the servo electric press brake, the higher the manufacturing cost. The heavy-duty ball screw pure electric bending machine can only be suitable for models below 60 tons, and the lifespan of machines with larger tonnage cannot meet the design standards. Therefore, pure electric press brake below 60 tons, especially below 40 tons, are a good choice.
