The motor core high-speed press is a device specially used for producing motor cores. The motor core is a very important part of the motor. It is usually made of multiple thin steel sheets pressed together, which plays the role of magnetic conductivity and reducing losses. The working principle of the high-speed press is mainly to stack silicon steel sheets into motor cores through a high-speed and high-pressure stamping process.
Working principle of high-speed press:
Raw material preparation: The raw material used by the high-speed press is thin silicon steel sheets, which usually have high magnetic permeability and are used to form the core of the motor. Silicon steel sheets are generally pre-punched into a certain shape or size, usually round or square sheets.
Lamination process: The high-speed press presses multiple steel sheets layer by layer through multiple stamping actions to form the motor core of the required shape. When these steel sheets are pressed together, they not only maintain good magnetic conductivity, but also improve efficiency by avoiding air gaps.
Stamping and pressing: High-speed presses usually use high-speed moving dies to stamp steel sheets. At high speed, the die quickly presses the steel sheets into the die cavity to form the specific shape of the motor core. The stamping process is automated, and after multiple stamping, pressing and exhausting, a motor core that meets the specifications is finally formed.
High-pressure drive: High-speed presses usually use hydraulic systems or mechanical transmission systems to provide high pressure, so that the punch has enough pressure to overlap and compact the steel sheets. The effect of high pressure ensures the accuracy and quality of the forming process, while avoiding defects such as bubbles and gaps.
Automated control: High-speed presses are usually equipped with automated control systems to control parameters such as stamping time, pressure and number of punches. This system ensures the forming accuracy and consistency of the core, while improving production efficiency.
Forming and demolding: After each stamping is completed, the formed part of the motor core will be removed from the mold. Usually on a high-speed press, the automated system will take out the formed core and send it to the next process, such as surface treatment, inspection, etc.
Summary: The motor core high-speed press machine stacks silicon steel sheets into motor cores through high-speed and high-pressure stamping. Its working principle mainly includes the preparation of raw materials, stacking of steel sheets, stamping, pressing process and demoulding. The high-speed press machine is characterized by its ability to efficiently and accurately manufacture motor cores that meet the requirements, and is widely used in the field of electric motor manufacturing.
