Grippers with magnets with detachable field

grippers with magnets with detachable field

Industrial equipment known as magnetic grippers are designed based on very strong neodymium magnets, produced by the sintering process, and equipped with a dedicated magnetic system that allows for detachable magnetic field. The use of strong magnets eliminates the need for external power supply. Switching connecting and disconnecting the magnetic field is based on the use of a manual lever, which allows for easy control of the force of the utilized magnets in the gripper. The device has the advantage of being small in size compared to its enormous magnetic force provided by magnets made of neodymium. Magnetic grippers are primarily used in locations where transporting and lifting various metal objects such as profiles, sheets as well as other objects that are susceptible to the action of a magnetic field.

The offered magnetic grippers are covered by a one-year warranty. They have a "CE" compliance declaration. The operational level of the magnetic gripper's acoustic pressure does not exceed 70dB, so the device is not treated as a source of noise.

Load Capacity of Magnetic Grippersshould be evaluated taking into account the factors described below:

  • During the operation with grippers, attention should be paid to the shape and thickness of the handled elements, as the load capacity of the gripper depends on these parameters of the given element. For each gripper model, we provide the relationship between the load capacity and the thickness of the lifted object. For example, solid cylindrical elements like reinforcement bars, cylinders, etc., reduce the nominal load capacity of the gripper by approximately 50%.
  • Please note that the minimum thickness of the lifted element is 2mm. Too thin elements may be bent and damaged. Additionally, they are less attracted due to suboptimal utilization of the gripper's magnetic field, caused by the saturation of the element and the dissipation of most of the field outside the handled element. Accordingly thick elements increase the load capacity efficiency by fully closing the gripper circuit. Below we provide a comparison of optimal steel thicknesses for each gripper model:

Appropriate performance curves that take into account the thickness of the lifted elements are located on the housing of each gripper. For safety reasons, it is necessary to consult the provided data before starting work.

The load capacity of the grippers also depends on the size of the air gap formed between the lifted element and the surface of the device. The gap is formed between the lifted element and the magnetic poles of the gripper. The load capacity efficiency decreases for all elements where the surface roughness parameter Ra exceeds 6.3mm - that is, for most objects, except those with precisely ground and very clean surfaces. For all other elements, the presence of an air gap should be taken into account, assuming, for example:

  • for rolled surfaces (rusty) - 0.1-0.3mm,
  • for porous and uneven surfaces, approximately 0.3-0.5mm.

    For each grip model, we provide the load capacity parameter depending on the thickness of the steel and the size of the air gap.

Appropriate performance curves taking into account the air gap are located on the housing of each handle. For safety reasons, it is necessary to consult the given data before starting work.

The load capacity of the handle may be weakened by the elevated temperature of the element and its surroundings. It is not permissible to lift elements with a temperature higher than the working temperature in an environment with a temperature higher than 80°C.

A very important parameter influencing the load capacity of the handle is the material from which the lifted element is made. Different ferromagnetic materials have different magnetic properties and, therefore, interact with the magnet differently. The force of this interaction (attractive force) depends on the structure and chemical composition of the material. Pure iron is naturally attracted the strongest, materials with small impurities, such as carbon steels, are slightly weaker, while cast iron is significantly weaker. The general rule is that the more iron in the material, the greater the load capacity of the handle. For example, for low-carbon steel, the efficiency coefficient is 0.95, for high-carbon steel - 0.90, for low-alloy steel - 0.75, and for cast iron - 0.50.
