4-meter Color Steel Bending and Shearing Machine

Here’s the detailed English version of the article introducing the 4-meter Color Steel Bending and Shearing Machine:

1. Product Overview

The 4-meter Color Steel Bending and Shearing Machine is a versatile piece of equipment designed for cutting and bending color steel sheets and thin metal plates. It is widely used in the construction industry, light steel structures, and workshop production. This machine combines shearing and bending functions, significantly improving production efficiency and reducing manual operation complexity.

2. Product Features

Shearing Length: The machine has a maximum shearing and bending length of 4 meters, suitable for processing large sheets of color steel.
Thickness Range: It can handle sheet thicknesses ranging from 0.2mm to 3.0mm, depending on the model and material properties, making it ideal for most thin sheet metal processing needs.
Power System: Typically powered by a hydraulic or mechanical transmission system, ensuring stable operation and smooth control. Hydraulic shearing machines provide high precision and robust working capability.
CNC System: Many modern bending and shearing machines are equipped with a CNC system, enabling automatic bending and cutting according to pre-set programs, enhancing precision and consistency in production.
Safety Features: Equipped with protective shields, safety barriers, and emergency stop buttons, ensuring operator safety during use.

3. Working Principle

Shearing Function: The machine cuts metal sheets by moving the upper blade up and down using hydraulic or mechanical force. The blades are made of high-strength materials, ensuring long-lasting use and resistance to wear.
Bending Function: Using bending dies and a bending beam, the machine applies pressure to bend the color steel sheet to a specified angle. The bending force is provided by hydraulic cylinders or mechanical systems, and the bending angle can be adjusted via the CNC system.

4. Application Fields

Construction Industry: Used for processing and manufacturing building materials such as steel-framed houses, garages, and color steel rooms.
Sheet Metal Processing: Ideal for manufacturing metal doors, windows, advertising boards, and casings for HVAC equipment.
Decorative Engineering: Custom processing of architectural decorative panels, particularly for curved or complex-shaped metal sheets.

5. Machine Structure

Body Structure: Typically constructed with high-strength steel welding to ensure rigidity and stability. The robust frame is capable of handling heavy-duty work over extended periods.
Blade Configuration: The machine features an upper and lower blade design. The upper blade moves up and down to shear the sheet, while the lower blade is fixed, generating the shearing force. The blades can be replaced to accommodate different materials.
Bending Dies: Customizable bending dies allow for the production of various shapes and angles in finished products.

6. Technical Specifications

Max Bending Length: 4000mm
Max Shearing Thickness: 3.0mm (depending on material)
Bending Angle Range: 0° to 120° (CNC models can adjust precisely)
Motor Power: 7.5kW – 15kW (depending on the model)
Working Speed: Shearing speed is 10-20 cycles per minute; bending speed varies depending on the angle and material.

7. Maintenance and Care

Lubrication System: Regularly check hydraulic oil and lubricate mechanical parts to ensure smooth operation.
Blade Maintenance: Keep the blades sharp and regularly inspect them, replacing them as needed to maintain cutting precision.
Safety Checks: Before each use, ensure that safety devices are functioning, and that the emergency stop button works to guarantee operational safety.
