How to reduce material waste in silicon steel winding machine equipment?


The silicon steel winding machine equipment reduces material waste through the following core technologies:

1、 Optimization of process parameters
Precision tension control: Optimize winding tension and speed, avoid strip stretching deformation or breakage, and reduce defect rate.
Real time temperature control: maintain the plasticity of silicon steel strip and reduce edge damage caused by stress concentration.
Simulation prediction process: By simulating the winding process through software, the risk of material deformation can be avoided in advance.
2、 Innovation in Equipment Structure
High precision guidance system: Improve the winding head and positioning device to ensure that the alignment accuracy of silicon steel strip is ≤ 0.1mm, and eliminate the misalignment loss of laminations.
Adaptive tensioning mechanism: dynamically adjust tension distribution to reduce local stress damage.
3、 Collaboration between Materials and Design
Topology optimization scheduling: adopting CAD/CAE integrated design to maximize the utilization rate of silicon steel strip (such as Tesla integrated die-casting technology to reduce losses by 40%).
Application of high-performance silicon steel: High permeability and low iron loss silicon steel (such as high-grade cold-rolled sheets) are used to reduce the rate of punching and shearing waste.
Non cutting processing technology: directly formed through 3D printing or precision casting, avoiding the corner waste generated by traditional cutting.
4、 Intelligent Management and Circulation
Closed loop recycling of scraps: Establish a real-time recycling system to remelt and reuse cutting waste materials (such as TSMC silicon utilization rate reaching 99.3%).
Pull production mode: Drive winding operations as needed to eliminate inventory waste caused by overproduction.

Combining the above measures, the winding machine equipment can increase the comprehensive utilization rate of silicon steel by 15% to 30%, while reducing energy consumption by more than 20%.
