Electromagnets for handling sheet metal coils
The handling or lifting of metal sheets in industrial environments can be carried out using two types of electromagnetic equipment, specifically designed to adapt to different applications, production needs, and safety levels.
- Classic rectangular electromagnets, ideal for standard applications with sheets of different thicknesses.
- Rectangular electropermanent magnets, designed to offer greater safety and energy efficiency in continuous or automated operations.
Required technical data
- Maximum and minimum outer diameter.
- Inner diameter.
- Coil height.
- Maximum coil weight.
- Bridge crane data (capacity, height, etc.)
Electromagnets for handling sheet metal coils
electromagnetic equipment
Handling of coils by their vertical axis
They are used for the rapid movement of straps and coils due to their flat surface or vertical axis. They have a large contact surface and can be made up of modules of two or three elements.
They are specially designed not to damage the edges of the strip or band and have a deep magnetic field that enters the body of the coil. However, this field is of relatively low intensity so as not to exert excessive force on the edge of the strip.
For automated installations, flow diversion electromagnets are usually supplied, in which the force is generated exclusively by permanent magnets, increasing safety compared to classic electromagnets.
For non-automated installations, we supply either classic electromagnets or electro-permanent switching magnets. The former are supplied with an emergency battery system to keep the load raised in the event of a power failure. The latter maintain the increased safety already provided by electro-permanent diversion magnets, with the difference that the internal permanent electromagnets are maneuverable.
Handling of coils by their horizontal axis
These are electromagnets with a powerful magnetic field that penetrates to great depths. Their articulated outer poles adapt precisely to the curvature of the coil, allowing them to be used with different outer diameters without the need for additional mechanical adjustments. This makes them a highly versatile tool for handling metal coils.
Its main use is the unit handling of sheet metal coils by their horizontal axis or curved surface, allowing for safer, more controlled, and more efficient operations, especially in processes where material integrity is a priority.
Among its most notable advantages is increased storage capacity, as there is no need to leave space between coils, as is the case with mechanical methods. In addition, there is a significant reduction in the time spent transporting and handling the material, optimizing operating cycles.
A key advantage is the elimination of marks or deformations on the surfaces of the coils, which often appear with traditional systems such as hooks or clamps.
