SC 160t 3200mm electro-hydraulic press brake for sale is a high-precision forming equipment widely used in the sheet metal processing industry, mainly for bending sheet metal such as carbon steel, stainless steel, and aluminum plates. This equipment uses a hydraulic system to drive the slide block up and down, combined with a CNC system to achieve high-precision bending control. Employing electro-hydraulic synchronous control technology, this equipment features high precision, high efficiency, and high stability, making it suitable for industries such as machinery manufacturing, electrical equipment, automotive parts, and metal structures.
1. Equipment Overview
160T×3200mm Electro-hydraulic Synchronous CNC Press Brake Machine:
- Bending Force: 160 tons (1600kN)
- Maximum Bending Length: 3200mm
This equipment utilizes a hydraulic system to drive the slide block up and down, applying pressure to the sheet metal through a die to achieve bending and forming. The bending angle, position, and program control are achieved through a CNC system.
The electro-hydraulic synchronous structure uses a proportional servo valve + grating ruler closed-loop control to ensure synchronous movement on both sides of the slide block, improving bending accuracy and stability.
2. Electro-hydraulic CNC Press Brake Working Principle
The equipment mainly utilizes hydraulic drive and CNC control to complete the bending process.
160T 3200MM Electro-Hydraulic Press Brake Work Process:
- Sheet Metal Positioning
The back gauge automatically moves to the set position.
- Slide Descending
Hydraulic oil pushes the cylinder to drive the slide downward.
- Sheet Metal Bending
The upper and lower dies apply pressure to the sheet metal, causing plastic deformation.
- Pressure Holding and Forming
Pressure is maintained to ensure angle stability.
- Slide Return
The slide rapidly rises to complete the bending process.
