CNC bending machines are core equipment in the machinery manufacturing and maintenance industries. With the rapid development of China’s manufacturing industry, the market demand for various types of plate processing continues to grow, and the requirements for processing accuracy and production efficiency are also increasing. This article will explore the key factors and practical strategies for optimizing the efficiency of CNC bending machines.
Key factors for improving the efficiency of CNC bending machines
1. Pre-production preparation and setting optimization
Before processing products of specific specifications, it is necessary to reasonably set processing parameters and planned production quantities. Efficient pre-preparation can significantly reduce downtime and adjustment frequency during production. Specific optimization measures include:
- Batch production plan: Arrange workpieces of the same material and similar specifications in a centralized manner to reduce mold change and parameter adjustment time
- Mold preparation and preset: Prepare the required molds in advance, and perform preset and inspection to ensure installation
- Process parameter optimization: Preset the optimal bending force, speed and depth parameters according to material characteristics and workpiece requirements
- Preventive maintenance inspection: Complete equipment inspection before production to ensure that the hydraulic system, electrical system and mechanical components are in the best condition
When the processing reaches the preset number, the system will prompt the operator, who can choose to reset the parameters to continue production or switch to temporary operation mode to keep the production line running continuously.
2. Equipment selection and configuration optimization
Choosing a high-quality CNC bending machine is the basis for improving work efficiency. High-quality bending machines have the following features:
- Professional control system: using dedicated CNC systems from well-known manufacturers such as Delem in the Netherlands, with high precision and high stability
- High-precision components: equipped with imported grating rulers, precision hydraulic valves and high-performance servo motors to ensure motion accuracy
- Electro-hydraulic proportional servo synchronization technology: achieves precise control of parallelism up to 0.02mm, with excellent anti-eccentric load capability
- Multi-axis linkage control: the slider stroke (Y1, Y2) and the back stop (X, R, Z) are all automatically controlled by computers to achieve seamless coordination
- High-precision transmission system: the back stop adopts ball screw and rolling guide design, which is sensitive and reliable, and has higher repeat positioning accuracy
3. Production process optimization strategy
Operation skills improvement
- Regularly train operators to master all functions of the equipment
- Establish standard operating procedures (SOP) to ensure operation consistency
- Promote best practice cases and share efficient operation skills
Process parameter optimization
- Establish parameter database according to different materials
- Use the simulation function of the control system to pre-verify the bending effect
- Continuously optimize the bending sequence and reduce the number of workpiece flips
Application of auxiliary tools
- Adopt a quick mold change system to reduce mold change time
- Use workpiece support auxiliary equipment to reduce the burden on operators
- Apply mold lifting and storage systems to improve mold management efficiency
Intelligent upgrade direction of CNC bending machines
1. Intelligent control system
Modern CNC bending machines are developing in the direction of intelligence, and the new generation of control systems have the following functions:
- Offline programming function: complete program compilation and simulation before production to reduce equipment debugging time
- Automatic process calculation: automatically calculate the best bending parameters according to material characteristics and workpiece requirements
- Visual assistance system: improve operation accuracy through camera-assisted positioning and detection
- Networking function: achieve seamless connection with the enterprise ERP/MES system to optimize production planning and resource allocation
2. Automation and flexible production
- Robot loading and unloading system: reduce manual intervention and improve continuous production capability
- Automatic mold changing system: greatly reduce mold changing time and adapt to multi-variety small batch production
- Flexible production unit: integrate bending, punching, welding and other processes to achieve one-stop processing
Equipment maintenance and maintenance efficiency impact
Scientific maintenance strategy is essential to ensure long-term and efficient operation of equipment:
| Maintenance Area | Key Actions | Benefits |
|---|---|---|
| Preventive maintenance plan | Regularly check and maintain key components | Reduces unexpected failures |
| Hydraulic system focus | Check oil quality, replace filters, keep system clean | Ensures consistent performance |
| Precision component maintenance | Clean and lubricate grating scales and guide rails | Maintains accuracy |
| Operating environment management | Control workshop temperature and humidity | Reduces environmental impact on precision |
| Spare parts management | Establish key spare parts library | Minimizes downtime from component failures |
Conclusion
Improving the working efficiency of CNC bending machines is a systematic project, which requires comprehensive consideration from equipment selection, parameter optimization, process improvement, personnel training and other aspects. With the development of intelligent manufacturing technology, CNC bending machines will achieve a higher level of automation and intelligence, bringing higher production efficiency and processing accuracy to the metal sheet processing industry.
Selecting high-quality CNC bending machines and using and maintaining them scientifically is the basis for ensuring production efficiency and product quality.
