These detailed designs ensure long-term stable operation of the equipment.
How to Choose the Most Suitable Model Based on Enterprise Needs
Considering processing material specifications is the primary factor in model selection. Different enterprises process vastly different busbar specifications, requiring equipment capacity selection based on the thickness and width of commonly processed materials. Mainstream CNC busbar punching and shearing machines typically offer processing capacities up to 12mm thick and 160mm wide, while heavy-duty equipment can even handle busbars up to 16mm thick and 250mm wide. If an enterprise primarily produces small switchgear, a compact model with a worktable size of 1230×900mm may suffice. For large substation projects, large equipment with an X-axis travel of 1200mm and Y-axis effective travel of 950mm is required.
Evaluating production efficiency requirements relates to enterprise capacity and benefits. For enterprises with fast production rhythms and large order volumes, priority should be given to turret-type multi-station models. This equipment is equipped with multiple punching dies, shearing dies, and embossing dies, enabling automatic die selection and positioning, significantly reducing die change time. For enterprises with heavy production tasks, models where three processing units are controlled by three separate pump stations can be selected, allowing simultaneous operation of punching, shearing, and bending units, maximizing equipment utilization.
Analyzing equipment accuracy requirements is key to ensuring product quality. The high-low voltage switchgear manufacturing industry has extremely high requirements for busbar processing accuracy. High-quality CNC busbar punching and shearing machines can achieve positioning accuracy of ±0.1mm and hole spacing control accuracy within ±0.10mm per meter. For ordinary application scenarios, equipment with punching accuracy below 0.05mm is sufficient. When selecting models, enterprises should choose machines with appropriate accuracy levels based on their product precision requirements, avoiding both over-investment and insufficient accuracy.
Considering equipment reliability and after-sales service is important for ensuring production continuity. As key production equipment, the reliability of CNC busbar punching and shearing machines directly affects enterprise delivery capabilities. When selecting, attention should be paid to the brand and quality of core components such as motors, oil pumps, solenoid valves, electrical components, linear guides, and ball screws. Simultaneously, the supplier's after-sales service response speed is crucial. Quality suppliers provide timely technical support and parts supply, ensuring quick recovery when equipment fails.
Safety Operation Regulations for CNC Busbar Punching and Shearing Machines
Pre-operation preparation is the first step to ensuring safety. The oil tank must be filled before starting for the first time to prevent damaging the oil pump. Operators must thoroughly read the user manual to familiarize themselves with the machine's structure, performance, and operation methods. If the ambient temperature is below 0°C, the machine should be idled for a few minutes before work.
Safety measures during operation are crucial. Never place hands or any part of the body between the upper and lower dies (blades) during operation to prevent accidents. Installation, debugging (die adjustment, blade gap adjustment), or disassembly of dies must be performed by personnel familiar with the machine according to specified procedures. Always select the appropriate shear blade and punch die clearance based on the thickness of the copper or aluminum bar. Always stop the machine when changing dies to avoid danger.
Safe shutdown after operation is equally important. After completing operations, shut down safely in sequence: first turn off all unit operation buttons, then the power switch on the control panel, followed by the main circuit air switch, and finally the workshop power switch. This series of standardized operations can effectively prevent accidental equipment startup and power safety hazards.
Maintenance and Care: Key Measures to Extend Equipment Life
Regular inspection and maintenance are the foundation for ensuring long-term stable operation of equipment. Regularly check the sharpness of blade and punch die edges; sharpen or replace them promptly if dull. Keep the oil clean and oil passages clear; lubricate the moving parts of each unit every shift. Ensure electrical and hydraulic components operate flexibly and are positioned correctly; immediately stop and inspect if abnormalities are found.
Hydraulic system maintenance is the focus of equipment care. The hydraulic oil tank should be cleaned regularly, and hydraulic oil replaced according to the specified cycle to ensure oil cleanliness. Hydraulic hoses should be inspected regularly and replaced if aging or damage is found to prevent pressure leakage. For equipment with turret-type punching systems, regularly clean the turret stations to prevent metal chip accumulation from affecting die positioning accuracy.
CNC system maintenance should not be overlooked. Keep the control panel clean to prevent dust and oil from entering the control system. Regularly back up system parameters for quick recovery in case of system failure. The CNC system battery should be replaced according to the specified cycle to prevent data loss. When equipment is out of service for extended periods, power it on periodically to keep the internal system dry.
Future Trends: Intelligence and Automation as Main Directions
Improved intelligence levels are a clear trend in CNC busbar punching and shearing machines. New generation equipment integrates more advanced CNC systems with data memory functions. Users can pre-input processing data, and the system retrieves this data for processing; alternatively, processed workpiece field data can be stored in the system at any time and retrieved for reuse. This intelligent functionality greatly simplifies production processes for repeat orders and improves production efficiency.
Increased automation is another important development trend. High-end CNC busbar punching and shearing machines have achieved multiple processing functions with a single clamping. Operation only requires clamping the busbar to be processed in place at one time, then completing the required punching, cutting, embossing, and other tasks in coordination with touch screen programming and related operations. This automated processing method reduces manual intervention, lowers labor intensity, and improves processing accuracy and consistency.
Environmental protection and energy-saving designs are receiving increasing attention. Modern CNC busbar punching and shearing machines use efficient hydraulic systems that optimize energy use and reduce consumption.
