Description
Technical field
The present invention relates to a kind of cooling structure, specifically refers to a kind of method cooled down to magnetizer.
Background technology
Metal adhesive is to realize technology that metal is connected with nonmetallic solid interface with metal and metal using metal repairing agent, traditional physical connection mode and attachment chemistry are different from type of attachment and theoretical side, metal adhesive is that infiltration of the Jing liquid adhesives to two solid interfaces forms a firmly overall process with combining under room temperature or middle temperature.Bonding force is the sum total of physical connection power and chemical bond attachment force, and bonding interface can not only transmit stress and can seal, anti-corrosion, surface and overall can enter the machinings such as driving, brill, milling.Metal adhesive can make molding at normal temperatures, and high temperature is adapted to Jing after intermediate temperature setting（200-700℃）And low temperature（-196℃）Under the conditions of work；Bonding interface stress distribution is uniform, and fatigue resistance is higher by the 1-2 order of magnitude than riveting, weldering；Bonding has the performances such as sealing, anti-corrosion, insulation, heat-insulated, magnetic conduction, conduction, heat transfer.Structure design can be simplified, reduce volume size, save energy and material, be improved effect, the reduction of erection time, improve performance and improve quality level.Magnetize is to make magnetisable material magnetization or the magnet for making magnetic not enough increase magnetic.Usually it is to be magnetized can carrying magnetic object be placed in the magnetic field formed by the coil that unidirectional current passes through.Magnetizing direction can be divided into thickness magnetize, radial magnetizing etc..The operation principle of pulsed magnetizer：By the pulse high current of moment in coil, coil is made to produce of short duration ultrastrong magnetic field.It is suitable for the occasion of high coercive force permanent-magnetic material or complicated multipole magnetization.It is widely used in permanent magnet material production and applies enterprise, is suitable for the magnetization of all kinds of permanent magnet material parts and part, such as：Al-Ni-Co series row, ferrite series, rare earth permanent magnet series etc., with it is efficient, reliable the characteristics of.Equipment is to work place power configuration without particular/special requirement, easy to use and flexible.But, during magnetizing, substantial amounts of heat can be produced, magnetizing coil and product can be heated and temperature is raised, and not only be not easy to operation, and, if temperature is too high, the problems such as cut occurs in the outward appearance that can cause product, size is uneven, the magnetic for being more likely to result in product is uneven, have impact on the performance of product.
The content of the invention
It is an object of the invention to provide a kind of method cooled down to magnetizer, during solving the problems, such as to magnetize at present, magnetizing coil and product temperature are too high, reduce its temperature, it is ensured that the purpose of the stable performance of product.
The purpose of the present invention is achieved through the following technical solutions：
A kind of method cooled down by magnetizer, including magnetizing coil, the axis of magnetizing coil be cavity to magnetize chamber, the interior of the magnetizing coil is provided with pipeline, the two ends of pipeline side wall upper shed connection water inlet pipe and outlet pipe respectively in magnetizing coil.The process for magnetizing is such：Capacitor is filled with into high direct voltage voltage first, then by coil discharge that a resistance is minimum；The peak value of discharge pulse current produces a powerful magnetic field up to tens thousand of amperes, this current impulse in coil, and the magnetic field makes the hard magnetic material permanent magnetization being placed in coil, after external magnetic field is decorporated, also has remnant field in hard magnetic material.Magnetizing coil is in cylinder on the whole，Its internal axis direction is cavity structure，The cavity structure is used for the hard magnetic material for placing cylinder，During magnetizing，Magnetizing coil repid discharge electric current forms powerful magnetic field after coil，Magnetic direction inside the hard magnetic material in cavity structure is subject to the effect of external magnetic field and becomes always，Form the magnetic field of itself，Complete the process of magnetizing，Electric current is by can produce many heats during coil on coil，Instantaneous heat accumulation raises can magnetizing coil and the temperature moment of hard magnetic material，When temperature it is too high，For the performance of the product that magnetizes has affected，To this，Need during spurt to lower the temperature magnetizing coil and hard magnetic material，As magnetizing coil has certain thickness side wall，Interior is provided with pipeline，Two ports of pipeline are on the side wall of magnetizing coil，Connect water inlet pipe and outlet pipe respectively on two ports，Water inlet pipe and outlet pipe are connected respectively to coolant，When magnetizing，Cold water enters water inlet pipe，Through the heat that magnetizing coil side wall is absorbed while pipeline，Become high-temperature water，Then flow out from outlet pipe，So，The heat exchange that cold water is produced during magnetizing is to cold water and then takes out of，Effectively reduce the temperature of the temperature and the material that magnetizes of magnetizing coil，Ensure that the performance of product，Avoid physical change and chemical change which occurs because temperature is too high.Pipeline is placed with two ways inside magnetizing coil：
The first, described pipeline is the helical channel around magnetizing coil axis.Further, when the length of magnetizing coil is larger, screw type passage can be adopted so that cold water fully absorbs heat and out, passage axle centered on the axis of magnetizing coil, its number of turn can be set according to actual needs.
Second, described pipeline forms cylindric in the side wall of magnetizing coil.Further, when magnetizing coil length is less, cylindric passage can be adopted.
The present invention compared with prior art, has the following advantages and advantages：
A kind of method cooled down by magnetizer of 1 present invention, when magnetizing, cold water enters water inlet pipe, through the heat that magnetizing coil side wall is absorbed while pipeline, become high-temperature water, then flow out from outlet pipe, the heat exchange that cold water is produced during magnetizing is to cold water and then takes out of, effectively reduce the temperature and the temperature of material of magnetizing of magnetizing coil, it is ensured that the performance of product, it is to avoid its physical change occurred because temperature is too high and chemical change；
A kind of method cooled down to magnetizer of 2 present invention, simple structure, cooling water are eaily used, and cost is very low；
A kind of method cooled down to magnetizer of 3 present invention, magnetizing coil its cooling rate after cooling are significantly larger than the speed of natural cooling, when convenient operation, improve production efficiency.
