Buildup Device Vibration Damping for High-Speed Core Lamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional buildup devices face challenges in reducing the load caused by vibration when attempting high-speed rotation of the rotary drive unit, leading to potential motor and component failure, while also struggling to maintain high-speed core lamination efficiency.
Innovation Solution
The buildup device incorporates a servomotor with a damping plate, upper and lower plates, and vibration absorbing members to restrict vibration freedom and absorb vertical vibrations, allowing for high-speed core lamination with reduced load on motor components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rotation speed of the rotary drive device is increased to achieve high-speed core lamination, then productivity is improved, but vibration increases causing load on motor and components leading to potential failure
Solution Approach 1:
The patent converts the harmful vibration generated during high-speed rotation into a beneficial effect by using vibration absorbing members (dashpots) that dissipate the vibration energy. The vibration that would normally cause damage is now controlled and utilized to reduce load on the motor while maintaining high rotation speeds, thus improving both productivity and reliability simultaneously
2Reliability
If vibration is reduced by using vibration absorbing members, then load on motor is reduced improving reliability, but device complexity increases
Solution Approach 1:
Instead of attempting to reduce vibration throughout the entire system, the patent applies vibration absorbing members locally at specific critical points - namely at the die holder and pressurizing holder where vibration generates the most harmful effects. This localized approach reduces motor load and improves reliability without requiring complex system-wide modifications

AI summary
There is provided a buildup device that builds up a plate-shaped core after rotating the core by a predetermined angle, and that includes a servomotor, a damping plate attached to the servomotor, at least one upper plate provided above the damping plate, at least one lower plate provided below the damping plate, and a plurality of vibration absorbing members attached to the damping plate. The upper plate and the lower plate restrict a degree of freedom of vibration to one direction, and the vibration absorbing members absorb vertical vibration.
