What is Electric Press Brake
All-electric servo bending machine is a servo motor driving heavy-duty ball screw to actuate the slider to do reciprocating motion (or servo motor driven belt and dynamic pulley set), and driving the upper die on the slider to apply force to the lower die on the table, so as to bend the metal plate and form it into the required shape and size.
Scope of Use of Electric Press Brake
- Electrical copper and aluminum busbar bending, keep thickness within 10mm and width within 100mm;
- All kinds of metal plate bending, keep thickness within 3mm and length within 2000mm.
Characteristics of Electric Press Brake
1. It does need to fill the hydraulic oil, which could be operated immediately after powering on
Electric Press Brake drive is completely mechanical transmission, so it can be used in factories with high environmental requirements. It also could avoid oil pollution of the environment.
2. Servo motor direct drive, high response, energy saving and power saving.
Comparison of energy consumption between hydraulic bending machine and Electric Press Brake
Pure Electric Press Brake is driven by the servo through the mechanical structure of the direct drive, eliminating the need for excessive transmission of hydraulic pressure, so as to realize high transmission efficiency. The servo motor load would also change in a real time with the change of the bending process pressure. The energy consumption is quite low when the equipment is powered but does not work, greatly reducing the loss of electricity. Servo motor direct drive response up to 100ms or less, the work beat is much higher than the hydraulic bending machine, the number of bending per minute can be more than 50 times, greatly increasing the efficiency.
1. Full closed-loop control system, higher precision.
The drive device is servo motor, the feedback device is magnetic scale, the system could monitor the real-time position of the slider, whether it has reached the required running position of the slider.
2. Heavy-duty ball screw drive bending pressure, long life.
Heavy-duty ball screw dynamic load is more than 3 times of the full load, not easy to produce fatigue, high transmission efficiency, and the life of the screw with the full load could reach up to 10000000 revolutions.
However, due to heavy-duty ball screw dynamic load limit, the tonnage of the Electric Press Brake can not be too large which shall be less than 60 tons, and the tonnage of the dynamic pulley structure could reach up to 130 tons.
Mini electric press brake driven by servo motor, CNC control, bending pressure 3-12 tons, bending length 200mm to 600mm.Official website address：www.longbomachine.com
