C-Section Steel Machine

A specialized equipment for producing C-section steel (cold-formed steel), widely used in steel structure buildings, factories, warehouses, bridges, mechanical manufacturing, and other fields. C-section steel is named for its cross-sectional shape resembling the letter "C," featuring lightweight, high strength, and easy installation. Below are its main advantages:  

### **I. Forming Main Machine**  

1. **Feeding**: Guide shaft + guide wheel  

2. **Leveling**: Upper 3 rolls + lower 4 rolls + 1 guiding conveyor, polished and electroplated  

3. **Main Forming**: 16 forming stations  

4. **Ribbing**: Straight ribs  

5. **Guiding Conveyor**: Equipped with transmission, driven by upper and lower shaft gears  

6. **Punching**: Single hole + double holes (14×28mm) punched after forming  

7. **Shearing**: Stepless shearing system after forming, no need to change blades for shearing  

### **II. Control System**  

1. **Main Control Cabinet**: 1 unit  

2. **Model Changeover**: PLC controls four reducers (sliding rail: 35mm linear guide rail)  

3. **External Controller**: 1 unit (for convenient jog control of forward/backward movement during production and debugging)  

### **III. Transmission System**  

1. **Hydraulic Motor**: Tailermusi  

2. **Hydraulic Station**: 22KW power (tank capacity: 500 liters)  

### **IV. Coil Uncoiler**  

1. **Load Capacity**: 5 tons  

2. **Tensioning Method**: Hand-operated (four-link mechanism with central outward tightening)  

3. **Brake**: Spindle clamping  

### **V. Material Support Table**  

1. **Support Frames**: 3 units  

2. **Support Method**: Frame constructed by welding channel steel and angle steel, with rollers installed on the surface  

### **VI. Performance Parameters**  

1. **Rollers**:  

   - **Material**: GCr15 bearing steel  

   - **Processing**: CNC-machined, heat-treated to HRC 58–60, precision-turned, polished, and electroplated.  

2. **Main Shaft**:  

   - **Diameter**: Processed from 80mm raw round steel  

   - **Material**: 40Cr steel  

### **Key Terminology Notes**  

- **Tailermusi**: Official English name of the hydraulic motor brand (confirmed by supplier documentation ).  

- **Stepless Shearing System**: Refers to a variable-speed shearing mechanism without fixed stages, ensuring precise cutting .  

- **GCr15 Bearing Steel**: Standardized as "High-carbon chromium bearing steel" in GB/T 18254-2002 .  

- **40Cr Steel**: A common alloy structural steel widely used in machinery manufacturing .
