Press Brake

Overview of sheet metal processing equipment

As a basic process in modern manufacturing, sheet metal processing requires a series of professional equipment to complete key processes such as cutting, bending, forming and shearing. These equipment, from traditional hand tools to advanced CNC machine tools, constitute a complete sheet metal processing system.

Classification of core processing equipment

1. Bending and forming equipment

CNC Press brake is the core equipment of modern sheet metal bending, with the following characteristics:

• Adopt hydraulic or servo motor drive system

• Equipped with high-precision back gauge (accuracy can reach ±0.01mm)

• Programmable control of multi-axis linkage

• Typical processing thickness range: 0.5-25mm

Auxiliary bending equipment includes:

• Bench Press brake: suitable for small workpiece processing, the maximum processing length is usually 1-2 meters

• Pipe bending machine: specially used for bending of pipes and special-shaped materials

• Manual folding machine: suitable for simple bending operations with small batches and low precision requirements

2. Cutting equipment series

Mainstream CNC cutting equipment:

• Laser cutting machine: processing accuracy can reach ±0.05mm, suitable for complex contour cutting

• Plasma cutting machine: suitable for thick plate cutting (up to 50mm)

• Water jet cutting machine: no heat affected zone, suitable for special material processing

Traditional cutting tools:

• Electric shearing machine: maximum shearing thickness can reach 6mm

• Manual shearing tools: including straight shear, circular shear and combination shear

• Metal punching and shearing machine: suitable for large-scale standard shape cutting

3. Forming and processing equipment

Advanced forming equipment:

• Hydraulic pressing machine: working pressure can reach more than 2,000 tons

• Roll forming production line: continuous processing length can reach tens of meters

• Spinning machine: suitable for precision forming of axisymmetric parts

Special forming tools:

• Rolling machine: three-roll or four-roll structure, can process 3-50mm plates

• Flanging machine: used to make various flange edges

• Bulging machine: realize local expansion forming of pipes

4. Shearing and finishing equipment

Professional shearing equipment:

• CNC shearing machine: Maximum shearing length can reach 6 meters

• Swing shearing machine: Adjustable shearing angle to reduce deformation

• Vibration shearing machine: Suitable for shearing of complex curves

Surface treatment equipment:

• Deburring machine: Automatically removes burrs on cutting edges

• Polishing machine: Achieve mirror effect on the surface

• Sandblasting machine: Improve surface adhesion and appearance
