How can Manhart (Guangdong) CNC Machine Tool Co., Ltd. achieve energy-saving in oil electric hybrid drive?

The oil electric hybrid drive technology adopted by Manhart (Guangdong) CNC Machine Tool Co., Ltd. for the oil electric servo bending machine is mainly achieved by combining the advantages of hydraulic drive and electric drive to achieve energy conservation.

Hydraulic drive has the advantages of high torque, low speed, and high load, which can provide strong bending force and is suitable for heavy-duty bending and continuous high-strength bending operations. However, hydraulic drive also has its shortcomings, such as low energy efficiency, high heat generation, and unstable transmission speed.

Electric drive, especially servo motor drive, has the characteristics of high energy efficiency, high precision, and fast response, making it suitable for bending operations that require fast response and high precision. However, using electric drive alone may not meet the requirements when high torque and high load are required.

The hybrid drive technology of oil and electricity optimizes the collaborative work of hydraulic and electric drives to achieve energy conservation and efficiency. Specifically, in bending operations, machines can intelligently switch between hydraulic and electric drives based on actual conditions and needs. For example, when a large bending force is required, hydraulic drive can be used; When fast response and precise control are required, electric drive is used. This intelligent switching can maximize the advantages of both driving methods while avoiding their shortcomings, thereby improving energy efficiency and achieving energy conservation.

In addition, hybrid oil electric drive technology can also achieve energy recovery. For example, during the descent or return process of a bending machine, the descending gravity can be converted into hydraulic energy through the hydraulic system for storage, and then released when needed. This technology of energy recovery and reuse can also improve energy efficiency and further achieve energy conservation.

In summary, by optimizing the collaborative work of hydraulic and electric drives and achieving energy recovery and reuse, Manhart (Guangdong) CNC Machine Tool Co., Ltd.’s oil electric servo bending machine has achieved the goal of energy conservation.
