Progressive Lamination Die is a die technology widely used in precision machining. It is mainly used to produce laminated sheets in the core components of motors, transformers and generators. These laminated sheets are usually made of silicon steel or other magnetic materials. After continuous stamping by multiple stations of the die, they are formed into laminated sheets with precise dimensions and complex shapes, which are used to improve the electromagnetic performance and energy efficiency of the equipment.
Working principle of progressive lamination die
The core features of progressive lamination die are "progressive" and "lamination". During the processing, the material (usually metal strip) is driven by the press and passes through multiple stations of the die to gradually complete the processes of punching, trimming, folding, forming and lamination. This method can achieve efficient and high-precision production, especially for the manufacture of large quantities of parts. Through the cooperation of automated equipment, the die can also complete the welding or bonding between the laminated sheets to form a stable component structure.
Main application areas
Motor manufacturing
Progressive lamination die is widely used in motor manufacturing, especially in the rotor and stator lamination processing of asynchronous motors and permanent magnet synchronous motors. It can produce silicon steel sheets with high precision and low loss, improving the efficiency and operating stability of the motor.
Transformer manufacturing
The core components of the transformer are usually composed of multiple laminates. The progressive lamination mold can produce laminations with complex shapes and consistent sizes to meet the strict requirements of the transformer for magnetic flux distribution and energy loss during the power transmission process.
Power generation equipment
In wind power generation, hydropower generation and other new energy fields, the rotor and stator of the generator need to use high-performance laminates. The high-efficiency processing method of the progressive lamination mold can meet the industry's demand for large quantities of high-quality parts.
Automotive electrification field
With the rapid development of new energy vehicles, progressive lamination molds are increasingly used in electric vehicle drive motors. The high-precision laminations produced by it can improve motor efficiency and extend vehicle range.
Advantages and prospects
The outstanding advantages of progressive lamination molds are their high precision, high efficiency and low material waste. Compared with traditional molds, its multi-station stamping design not only shortens the production cycle, but also significantly reduces production costs. With the development of industrial automation and intelligence, progressive lamination molds are evolving towards a more flexible and efficient direction, and are gradually becoming one of the indispensable technologies in the field of high-end equipment manufacturing.
