Magnetic system for levitation and breaking of metal pieces
Problem Statement

The current methods for braking and guiding metal pieces, like rods, rely on contact-based systems that cause wear and restrict production speeds. These methods involve physical cylinders or channels, leading to friction and limiting the rate at which metal pieces can be processed. Additionally, these systems often require substantial physical infrastructure, which adds to costs and maintenance efforts. As a result, there is a need for a non-contact, efficient braking and guiding system for metal pieces that can enhance production rates and reduce wear and tear on the equipment.

Abstract

This invention introduces a magnetic system designed to levitate and brake metal pieces, such as rods, using magnets arranged around their path of motion. Unlike traditional methods that rely on physical contact and friction, this system utilizes electromagnetic forces to lift and slow down the metal without touching it. This innovation aims to enhance efficiency and reduce wear in industrial processes like metal rolling. By adjusting the placement and strength of magnets, the system optimizes both lifting and braking forces, enabling smoother handling and faster production rates.

Uniqueness of the Solution
  • Strategic Magnet Arrangement and Adjustable Strength: Magnets are strategically positioned around the axis of metal piece motion, utilizing adjustable electromagnets to control braking forces effectively. 
  • Sturdy Structural Mounting for Efficient Force Application: Mounted on robust structures like trusses or channels, ensuring stable and durable application of balanced vertical lift and horizontal stability forces. 
  • Non-contact Operation for Reduced Wear and Longevity: Operates without physical contact, minimizing wear and ensuring prolonged system longevity. 
  • Integrated Adaptive Control System for Precision: Equipped with sensors and responsive controls for precise adjustments to magnetic fields, optimizing operational efficiency. 
  • Versatile Application Capability Across Industries: Handles various sizes and types of ferromagnetic metal pieces, offering operational versatility across multiple industrial sectors. 
  • Enhanced Safety and Reliability with Minimal Downtime: Ensures safe handling without mechanical contact or friction, enhancing operational reliability and minimizing maintenance downtime.
