Bending machines, utilizing straightforward molds to form metal sheets into specific forms, are extensively used across different sectors including electronics, construction, and hardware manufacturing.
These machines are divided into two main types: hydraulic and all-electric. Hydraulic bending equipment typically encounters challenges like lagging responsiveness, limited accuracy, increased expenses, and the need for regular maintenance, which render them less effective than their all-electric counterparts.
Over 95% efficiency in mechanical main drives compared to less than 80% in hydraulic servo bending machines. And the efficiency is even lower after the aging and wear of the hydraulic system components.
Electric bending machines do not use hydraulic oil, eliminating the hassle of changing hydraulic oil and removing hydraulic components, avoiding the problem of hydraulic oil leakage and waste oil disposal in daily system maintenance, and reducing environmental pollution.
The response speed of the fully electric bending machine is more than 30% faster than that of the hydraulic bending machine.
The main drive of the electric bending machine is driven by a servo motor to drive the screw, and the transmission accuracy is higher. By measuring the bending angle of various specifications of plates, the bending angle error can be guaranteed within 0.5 degrees.
The transmission system of the fully electric bending machine is simple, and there is almost no maintenance cost, only regular lubrication is required.
The on-site bending machine system is driven by two direct drive motors, the motor and the slider are connected by a screw. The position feedback signal is sent to the bending machine system, and the two drives work in the speed mode (limit output torque). The position loop of the left and right motors is independently controlled by the bending machine system. The two drive units exchange data through the CAN bus, and judge the absolute position difference of the two motors in real time. If it exceeds the set value, the system will send a motor over-difference fault alarm.
Excellent speed regulation and large torque of the inverter ensure precise positioning and effective bending of high-hardness materials.
Smooth operation reduces material impact, lessening maintenance needs and extending the machine’s lifespan.
High operational efficiency with comprehensive motor and system protection, monitoring, and diagnostic functions, significantly improving system reliability.
Low energy consumption helps customers reduce production costs.
