Description

Technical Field

[0001] The utility model belongs to the technical field of lifting suckers, in particular to a permanent magnetic lifting sucker. Background Art

[0002] Permanent magnetic lifting chuck, also known as lifting permanent magnet, permanent magnetic lifting device, magnetic lifting device, magnetic lifting device, lifting magnet, permanent magnetic magnet, etc., is a lifting tool made of permanent magnetic material. It uses the strong magnetic field generated by permanent magnetic material to achieve the adsorption and lifting of workpieces. The permanent magnetic lifting chuck has the characteristics of small size, strong holding force, no electricity, almost zero residual magnetism, and high safety factor. It is divided into manual and automatic types. It uses contemporary high-performance Nd-Fe-B magnetic material neodymium iron boron, which makes it smaller in size, lighter in weight, and stronger in holding force. At the same time, its unique magnetic circuit design makes the residual magnetism almost zero, which improves the safety factor. The working principle of the permanent magnetic lifting chuck is to control the magnetic field strength in the permanent magnetic material to achieve control of the suction force of the chuck.
