Background technology
Electric permanent-magnet suction disc when sticking processing work because of its have that holding force is powerful, power-off not loss of excitation and energising power consumption is extremely low instantaneously etc. that advantage is widely used in machining and lifting field, but because the inner main magnet used of traditional electrical permanent magnetic chuck is neodymium iron boron, its operating temperature is up to 80 DEG C, exceed this temperature will demagnetize, even if change main magnet into high temperature resistant neodymium iron boron, its heatproof degree also can only reach 180 DEG C-200 DEG C.But in real work occasion, many electric permanent-magnet suction discs are had to need to carry out sticking processing work under 400 DEG C of-500 DEG C of worst hot cases, as shipyard, Gang Gou factory, large-scale engineering machinery manufactory and Die & Mold Manufacturing Companies etc. weld at workpiece, in cutting process, clamp or other mechanical device is used to carry out clamping, although some problems can be solved, but complete weld zone cannot be reserved, in welding or cutting process, workpiece temperature distortion is large, can only by repeatedly repeatedly clamping come cutting or welding processing, therefore traditional electric permanent-magnet suction disc cannot meet above-mentioned duty requirements.
At present, some manufacturers carry out sticking processing work be applicable to the operating mode of 400 DEG C of-500 DEG C of high temperature to meet electric permanent-magnet suction disc under, above the main body adhesive face of electric permanent-magnet suction disc, cooling body is set, though said structure can intercept the high temperature of workpiece in practical operation, but in order to ensure its enough suction, adopt the measure increasing reversible magnetic body height, the cost of manufacture of electric permanent-magnet suction disc can be increased like this, increase unnecessary financial burden to user.
Utility model content
The utility model for solve in known technology the technical problem that exists and provide a kind of be applicable to sticking temperature at 400 DEG C-500 DEG C high temperature workpiece, reduce cost of manufacture and the water-cooled magnetic module that can extend its service life.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is:
Water-cooled magnetic module, comprise module bodies and cooling water recirculation system, described module bodies is by disk body, be packed in the reversible magnetic body on disk body, be sleeved on the magnet exciting coil of reversible magnetic body outer ring, the multiple leading pole block and the main magnet be arranged between disk body two medial surface and leading pole block that are arranged on reversible magnetic body top are formed, it is characterized in that: described cooling water recirculation system comprises the cooling water pipe be coiled between main magnet top and leading pole block, be arranged on the water inlet pipe that is communicated with on disk body one side and with cooling water pipe and be arranged on the outlet pipe be communicated with on disk body another side and with cooling water pipe.
The utility model can also adopt following technical scheme:
Described cooling water pipe adopts copper pipe to make.
The height of described reversible magnetic body is less than 18mm.
Described main magnet adopts high-coercive force, resistant to elevated temperatures neodymium nickel cobalt material is made.
The advantage that the utility model has and good effect are: because the utility model adopts technique scheme; namely arrange copper pipe by arranging between main magnet top and leading pole block more; recirculated water is utilized to lower the temperature to magnetic module; large-scale workpiece to be welded or in gas flame cuttiug process; available protecting magnetic module can not be subject to temperatures involved; guarantee that workpiece is without distortion, and the service life of magnetic module can be extended.Because cooling water pipe is arranged between the main magnet top of magnetic module inside and leading pole block by this water-cooled magnetic module, without the need to considering the magnetic loss factor of magnet, therefore reversible magnetic body height can be shortened, it is made highly to be less than 18mm, the cost of manufacture of magnetic module can be reduced like this, alleviate the financial burden of user.This water-cooled magnetic module also according to the size of workpiece to be machined, can adopt flexible and changeable modular combination mode, expands the scope of application.Adopt electric control permanent magnet technology, only pass into immediate current when encouraging demagnetized state conversion, the course of work is electricity consumption no longer, therefore energy-conservation, dangerous without power-off loss of excitation, and handling safety is reliable.

Detailed description of the invention
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1-Fig. 2, water-cooled magnetic module, comprise module bodies and cooling water recirculation system, described module bodies is made up of disk body 1, the reversible magnetic body 3 be packed on disk body, the magnet exciting coil 4 being sleeved on reversible magnetic body outer ring, the multiple leading pole block 2 being arranged on reversible magnetic body top and the main magnet 5 be arranged between disk body two medial surface and leading pole block.Described cooling water recirculation system comprises and is coiled in cooling water pipe 6 between main magnet top and leading pole block, is arranged on the water inlet pipe 7 that is communicated with on disk body one side and with cooling water pipe and is arranged on the outlet pipe 8 be communicated with on disk body another side and with cooling water pipe, described water inlet pipe 7 passes through pipeline Bonding pressure water pump, (pressure water pump is not shown).
In the present embodiment, the mouth of pipe and the outlet pipe mouth of pipe of described water inlet pipe all adopt hydraulic quick coupler, simple and quick, can shorten the Job readiness time.
In the present embodiment, described cooling water pipe 6 adopts copper pipe to make, and injects cold water, is intercepted and taken away the heat of magnetic module by circulating chilled water, ensure that the service life of magnetic module by water inlet pipe 7 to the cooling water pipe 6 be arranged on above main magnet.
In the present embodiment, the height of described reversible magnetic body is less than 18mm, so not only can considerably reduce the cost of manufacture of magnetic module, can improve the market competitiveness; And its property indices all can reach technical requirement.
