It is suitable for high-speed stamping stator and rotor iron core parts of the motor adopt multi-station progressive die. This enhances die service life significantly.
The progressive die facilitates a streamlined stamping process: as the strip emerges from the coil, it undergoes leveling by a leveling machine and is then fed by an active feeding device.
Once inside the mold, the strip undergoes a sequence of operations, including blanking, forming, finishing, trimming, and active lamination of the iron core.
This method allows for efficient and continuous processing, increasing overall productivity. Known for speed and cost-effectiveness, progressive stamping dies are preferred in high-volume manufacturing.
Compound Toolings
Compound stamping dies perform multiple operations simultaneously within a single stroke. This type of die is particularly useful for intricate motor iron core designs that require multiple processes.
Integration of operations in one die enhances efficiency and reduces tooling needs. Ideal for complex medium and large-sized motor cores.
Notching Die
Rotary notching dies specialize in creating notches in laminated iron cores, a crucial aspect in reducing core losses and improving motor efficiency. This type of die utilizes a rotary motion to make notches in the core material.
The notching dies to optimize magnetic flux pathways and minimize energy losses, enhancing electric motor performance with precision and speed.
Other Related Molds
In addition to stamping dies, die casting molds are another essential type in motor manufacturing. These molds are employed in the process of die casting, where molten metal is injected into the mold cavity to create intricate shapes. Die casting is commonly used for producing complex motor components with high dimensional accuracy and surface finish.
Four Structural Features of Motor Iron Core Stamping Die
The main structural features of the stamping die for the stator and rotor core of the motor are:
