Motor Core Stamping Capability
The stamping capability of motor cores is a crucial indicator for measuring the technical level, production efficiency, and product quality of motor core manufacturing enterprises. Stamping capability involves multiple aspects, including equipment performance, process level, material utilization, precision control, and more. Below is a detailed description of the stamping capability for motor cores:
Equipment Capability
· High-Speed Presses: Utilization of high-speed precision presses with stamping speeds reaching hundreds or even thousands of strokes per minute, meeting the demands of mass production.
· Automation Level: Equipped with automatic feeding, automatic collection, and automatic inspection systems to achieve efficient and stable continuous production.
· Press Tonnage Range: Wide coverage of press tonnage (e.g., 25 tons to 500 tons), capable of adapting to stamping requirements for cores of different sizes and thicknesses.
Process Level
· Precision Blanking: Capable of high-precision blanking, with dimensional tolerances controlled within ±0.01mm, ensuring tightness and consistency during core stacking.
· Multi-Station Progressive Dies: Adoption of multi-station progressive die technology to complete multiple processes (e.g., punching, blanking, forming) in a single stamping operation, improving production efficiency.
· Complex Shape Processing: Ability to stamp cores with complex shapes (e.g., irregular slots, skewed slots, sector-shaped pieces), meeting diverse motor design requirements.
· Burr-Free Technology: Optimization of die design and stamping processes to reduce blanking burrs and lower subsequent processing costs.
Material Utilization
· High Material Utilization: Material utilization rates can exceed 85% through optimized nesting design and die layout, reducing production costs.
· Scrap Recycling: Equipped with scrap recycling systems to minimize material waste and comply with environmental requirements.
Precision Control
· Dimensional Accuracy: High dimensional accuracy of stamped cores, meeting stringent motor design requirements and ensuring stable motor performance.
· Geometric Tolerances: Strict control of flatness, parallelism, and perpendicularity of cores to guarantee quality after stacking.
· Consistency: Use of automated equipment and precision dies to ensure product consistency in mass production.
Production Efficiency
· High Production Capacity: High-speed presses combined with automated production lines enable daily production of tens of thousands or even hundreds of thousands of cores.
· Quick Die Change: Adoption of quick die change systems to reduce setup time and improve production flexibility.
· Continuous Production: Automated production lines support 24/7 continuous production to meet large-volume customer orders.
Die Design and Manufacturing
· High-Precision Dies: Use of high-precision die manufacturing technology to ensure long die life and stable stamping quality.
· Die Materials: Use of high-quality die steels (e.g., SKD11, DC53) to enhance wear resistance and fatigue resistance of dies.
· Die Maintenance: Regular maintenance and servicing of dies to ensure stability in the stamping process and consistency in product quality.
Quality Control
· Online Inspection: Equipped with online inspection equipment to monitor the dimensions, shapes, and surface quality of stamped parts in real time.
· Full Inspection and Sampling: Combination of full inspection and sampling systems to ensure the quality of each batch meets customer requirements.
· Traceability System: Establishment of a comprehensive quality traceability system to ensure problematic products can be traced, analyzed, and improved.
Customization Capability
· Flexible Production: Ability to customize stamped cores of different shapes, sizes, and performance based on customer requirements.
· Rapid Prototyping: Capability for rapid prototyping to shorten the development cycle of new products.
· Technical Support: Provision of end-to-end technical support from design optimization to production processes, helping customers achieve optimal product performance.
