Sheet metal bending is a forming process that bends metal sheets into predetermined angles and shapes. This technique is widely used in manufacturing, from simple L-shaped or U-shaped brackets to complex enclosures and housings.
Working Principle
The principle of sheet metal bending is to apply pressure on the sheet through molds (punch and die) installed on a bending machine (press brake), causing metal deformation under stress and forming the desired angle.
Types of Equipment
Hydraulic Press Brake: Powered by a hydraulic system, it provides large and stable bending force. Currently the mainstream bending equipment.
Servo Electric Press Brake: Driven by a servo motor, offering high precision, fast speed, and better energy efficiency.
Mechanical Press Brake: A more traditional machine that uses a flywheel and linkage mechanism. Less common today.
Applications
Electronics Industry: Enclosures, brackets.
Home Appliances: Refrigerator panels, washing machine housings, oven components.
Construction Industry: Door and window frames, decorative panels, ventilation ducts.
Machinery Manufacturing: Covers, bases, and components for various equipment.
