How to choose the groove cold forming machine correctly
Material characteristics : Select the machine model according to the type of material being processed, thickness (0.3~12mm), width (maximum 1250mm) and material (galvanized sheet, aluminum sheet, steel sheet, etc.).
1. The best way to choose a groove cold roll forming machine
Clarify processing requirements
Material characteristics : Select the machine model according to the type of material being processed, thickness (0.3~12mm), width (maximum 1250mm) and material (galvanized sheet, aluminum sheet, steel sheet, etc.).
Production scale : For large-scale production, it is recommended to choose high-efficiency hydraulic drive or CNC equipment, while small-batch and diversified production requires models with strong flexibility and convenient mold change.
Precision requirements : For high-precision scenarios (such as steel structures and bridge projects), mechanical equipment or equipment equipped with a CNC system should be selected to ensure precise control of the bending angle and radius.
Machine Types and Performance Evaluation
Hydraulic cold bending machine : suitable for bending large-diameter and thick-walled materials, providing high pressure and high stability.
CNC cold bending machine : automatic control is achieved through preset parameters, suitable for complex shapes and high precision requirements.
Roller type cold bending machine : suitable for small curvature radius and large-scale production, but attention should be paid to the durability of the roller.
Energy consumption and cost analysis
Prioritize equipment with high energy efficiency to reduce long-term operating costs; at the same time, maintenance costs need to be considered, such as the frequency of seal replacement and lubrication costs in hydraulic systems.
2. Key points for selecting tools and accessories
Dies and Rollers
The mold needs to be customized according to the material model. For example, the channel steel needs to match bending molds of different specifications such as No. 8 and No. 10, and the sharpness should be checked regularly to avoid burrs.
The rollers need to be coated with rust inhibitor every 10 days and should be thoroughly cleaned and rust-proofed before long-term shutdown.
Transmission system accessories
Chains, gears and other transmission parts need to be lubricated every half hour, the oil level in the reducer needs to be maintained at two-thirds and checked every 10 days.
Safety and control systems
Choose equipment equipped with safety features such as overload protection and oil temperature monitoring to ensure safe operation .
3. Matters Needing Attention in Material Selection
Raw material compatibility
Ensure that the ductility and strength of the material (such as cold strip, galvanized sheet) meet the requirements of the cold bending process to avoid cracking or deformation during processing.
Specification Adaptation
The material thickness and width must be consistent with the processing range of the equipment. For example, for plates with a thickness of more than 12 mm, a high-power hydraulic press must be used.
4. Maintenance methods of groove cold roll forming machine
Daily maintenance
Lubrication management : Add rust inhibitor to the roller every 10 days, add lubricating oil to the cutting die every half hour, and lubricate the transmission system regularly.
Cleaning and rust prevention : Clean up metal debris after shutdown, and perform rust prevention on the rollers and molds when idle for a long time.
Regular inspection and replacement
Severely worn cutters and punching dies need to be ground or replaced in time to avoid affecting the processing quality.
The circuit system needs to be checked regularly to prevent short circuits caused by dust and oil.
Professional maintenance
The manufacturer or professional technicians will debug the whole machine and calibrate the bending accuracy and hydraulic system parameters every year.
