How does the switchable feature of a shuttering magnet work?

2024-12-18

The switchable feature of a shuttering magnet allows for the easy activation and deactivation of its magnetic force, facilitating the quick setup and removal of formwork in precast concrete applications. Here’s how it works:

Mechanism of Switchable Shuttering Magnets

1. Magnetic Circuit Design: Shuttering magnets typically consist of a strong neodymium (NdFeB) magnet housed within a protective steel casing. This design forms a magnetic circuit that can be controlled externally. The circuit is engineered to provide significant attraction force to ferrous materials when activated, while also allowing for easy manipulation when deactivated.

2. Activation Method: The switchable feature is usually operated via a simple push-button mechanism located on the top of the magnet's casing. When the button is pressed, it alters the magnetic circuit, allowing the magnetic force to engage and securely hold the formwork in place against a steel table or other surfaces.

3. Deactivation Process: To deactivate the magnet, the user releases the button, which disengages the magnetic force. The user releases the button with a special lift lever, which uses the principle of leverage so the process is effortless.This allows for easy repositioning of the formwork without needing additional tools or mechanical assistance. The design minimizes physical effort and enhances efficiency during setup and breakdown processes.

4. Safety and Efficiency: The switchable feature not only improves operational efficiency but also enhances safety by reducing the risk of injury associated with heavy lifting or manual fastening methods. Workers can quickly activate or deactivate the magnets as needed, streamlining workflow in precast concrete production.

In summary, the switchable feature of shuttering magnets allows for efficient control over their magnetic force through a simple button mechanism, facilitating rapid adjustments in formwork placement while ensuring safety and ease of use in industrial applications.
