The reversible magnet steel is used in a main magnetic circuit; the coil is arranged around the reversible magnet steel and the non-reversible magnet steel is arranged at two sides of the reversible magnet steel as the auxiliary magnet steel. The magnet yokes are arranged at two sides of the reversible magnet steel and the non-reversible magnet steel. The end of the magnet yoke is connected with the magnetic pole. The main magnetic circuit consists of reversible magnet steel, coil, magnet yoke, magnetic pole and sucked objects and the auxiliary magnetic circuit consists of the non-reversible magnet steel and the non-reversible magnet steel magnetic conduction connecting board. The main magnetic circuit structure and the auxiliary magnetic circuit are connected into an integral structure by a non-magnetic conductor. The invention is suitable for swinging a plurality of square billets and high-temperature square billets after heat insulating process. The mobile magnetic pole can greatly increase the suction efficiency for a long period application. The invention greatly expands the application range of the electric-controlled permanent magnetic chuck and provides a new way for the development of the hoisting electromagnet.
Description
Technical field
The present invention relates to lifting magnet, specifically be meant in the handling process of magnetic material, only inhale, the blowing program is by the power supply Instantaneous Control, the electric-controlled permanent magnetic chuck that by the suction of permanent magnet absorbate is firmly held during carrying.
Background technology
In actual production process, the commercial production that is applied as of multiple lifting electromagnet provides service very easily, but electromagnet is in case outage, then must drop into emergency battery at once and could guarantee trouble free service, the control part complexity of electromagnet, components and parts are many, and the big grade of consumption of current all is problems that we must face.The use of permanent magnet sucking hoisting apparatus though safety, power saving all adopts the mechanical lever mode of operation, is difficult to realize arbitrary control.The electricity permanent magnet also has many producers to develop, and its following principal feature is arranged: the magnet steel in (1) magnet externally shows magnetic at ordinary times, and backing field and the magnetic field cancellation in the magnet of utilizing coil winding to produce when blowing are carried out blowing; (2) reversible magnet steel and irreversible magnet steel are carried out simple superposition, cause the decay of irreversible magnet steel magnetic easily and influence suction, the long back of work-hours is generation remanent magnetism easily; (3) be unfavorable for inhaling the weight of transporting air gaps.
Summary of the invention
The objective of the invention is to be improved, innovate, a kind of electric-controlled permanent magnetic chuck is provided at shortcoming that exists in the background technology and problem.
Technical scheme of the present invention is that a kind of permanent magnetism of coil, magnet steel, yoke, magnetic pole that comprises of structure has sucker, wherein:
Magnet steel is made up of reversible magnet steel and irreversible magnet steel, and reversible magnet steel is used for main magnetic circuit, and coil is arranged on around the reversible magnet steel, and irreversible magnet steel is arranged on reversible magnet steel both sides for auxiliary magnet steel;
The both sides of reversible magnet steel and irreversible magnet steel are provided with yoke, and the yoke end connects magnetic pole;
Described reversible magnet steel, coil, yoke, magnetic pole and absorbate are formed main magnetic circuit, and irreversible magnet steel and irreversible magnet steel magnetic conduction connecting panel are formed auxiliary magnetic circuit;
Described main magnetic circuit structure and auxiliary magnetic circuit connect structure in aggregates by non-magnetizer.
The present invention has following advantage and beneficial effect:
Concrete application scheme of the present invention is a characteristic of utilizing the pole polarity of alnico magnet to be easier to change, it is applied in the main magnetic circuit as reversible magnet steel, with coil winding around, can be by giving the polarity of coil instantaneous forward and reverse energising change alnico magnet magnetic pole.Auxiliary irreversible magnet steel is housed in the both sides of alnico magnet, and the polarity of the irreversible magnet steel of its curing must be arranged by certain requirement.Irreversible magnet steel generally can adopt nd-fe-b, samarium-cobalt alloy, Ferrite Material.In order to overcome working gas gap greatly to the influence of workpiece suction, the amount that alnico magnet uses is bigger, and the magnetic potential that energising back coil produces is correspondingly also very big certainly.Because the irreversible magnet steel that uses is installed in the avris bypass of main magnetic circuit, even the bigger reverse magnetic potential of the long-term generation of coil also can guarantee not impaired the subtracting of magnetic of irreversible magnet steel.A distinguishing feature of this invention is when to be the polarity that produces when the main magnetic circuit magnet steel opposite with the polarity of bypass magnet steel existence, produce the magnetic circuit of a closure between them in inside fully and fully show magnetic at the adsorption plane place of electric-controlled permanent magnetic chuck, when the polarity that the polarity that produces when the main magnetic circuit magnet steel and bypass magnet steel exist was identical, the adsorption plane of sucker demonstrated strong magnetic and reaches the purpose that firmly holds the absorbate body by exterior absorbate formation loop.
The present invention is fit to many square billets of handling, but through heat insulation processing handling high temperature square billet also, has detachable pole can improve suction usefulness greatly, and long-time result of use is still good.The range of use of electric-controlled permanent magnetic chuck has been expanded in this invention greatly, for a new approach has been opened up in the development of lifting electromagnet.
