As a new generation of high-end bending equipment, the electro-hydraulic servo CNC press brake is gradually becoming an important choice for many manufacturing enterprises to upgrade, thanks to its excellent performance, energy-saving features, and intelligent control methods. This article briefly introduces the structural principles, main features, and application advantages of the electro-hydraulic servo CNC press brake.
1. What is an Electro-Hydraulic Servo CNC Press Brake?
The electro-hydraulic servo CNC press brake is a CNC machine tool that uses an electro-hydraulic servo system to drive hydraulic cylinders, enabling high-precision bending of metal sheets. Compared with traditional hydraulic press brakes, the electro-hydraulic servo press brake uses a high-performance servo motor to drive the oil pump, precisely controlling the movement of the hydraulic cylinder, thus significantly improving energy efficiency, accuracy, and noise levels.
2. Structure and Working Principle
Structure
The electro-hydraulic servo CNC press brake mainly consists of the frame, ram, worktable, upper and lower dies, electro-hydraulic servo drive system, CNC system, back gauge device, and safety protection system.
Working Principle
The core is the electro-hydraulic servo drive system. The servo motor, according to the instructions from the CNC system, precisely adjusts the flow and pressure of the hydraulic oil pump, driving the hydraulic cylinder to move the ram up and down to achieve sheet bending and forming. The CNC system can set bending angles, sequences, speeds, and other parameters, ensuring high consistency and precision in processing.
3. Main Features
High Precision and Consistency
The electro-hydraulic servo technology enables more precise control of the ram position and bending pressure, greatly enhancing the machining accuracy and repeatability of products.
Energy Saving and Environmentally Friendly
The servo motor supplies energy on demand, reducing energy consumption. Compared to traditional hydraulic systems, it saves more than 30% energy; it also operates with lower noise, meeting environmental requirements.
High Degree of Intelligence
The advanced CNC system features automatic programming, process optimization, automatic compensation, and other functions. It is easy to operate and supports efficient batch production of complex parts.
Low Maintenance Cost
The electro-hydraulic servo system has a simple structure, low failure rate, and easy maintenance, greatly reducing equipment operation and maintenance costs.
High Safety
Equipped with multiple safety protection systems, such as light curtain protection and emergency stop devices, to ensure operator safety.
4. Application Fields
The electro-hydraulic servo CNC press brake is widely used in aerospace, automotive manufacturing, rail transit, household appliances, machinery manufacturing, sheet metal processing, and other fields. It provides strong support for efficient and high-precision bending of sheet metal parts (such as chassis, cabinets, doors, etc.).
With its advantages of high precision, energy saving, environmental protection, and intelligence, the electro-hydraulic servo CNC press brake is gradually replacing traditional hydraulic press brakes, becoming essential equipment for modern sheet metal processing enterprises to enhance their core competitiveness. As the manufacturing industry’s demand for automation and intelligence increases, electro-hydraulic servo CNC press brakes will play a greater role in more fields, promoting the sheet metal processing industry towards high-quality development.
