It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1, as shown in fig. 1, a magnetic material fixing apparatus includes:

a main platform 1;

and the magnet device 3 is positioned below the main platform and arranged in the main platform 1, and the magnet device 3 is used for fixing the magnetic material.

In the embodiment of the application, the main platform 1 is cuboid or round, the main platform 1 can also be polygonal with one concave end and one horizontal end, and the bottom surface of the main platform 1 is a plane structure parallel to the horizontal plane; in the embodiment of the present application, the main platform may be made of a magnetic material, where the magnetic material is a non-permanent magnetic material. Illustratively, the main platform is made of a steel material.

The magnet device 3 is a device which is made of a magnet and can adsorb magnetic materials, and is mainly used for fixing objects; the magnetic material is a material which can react in a certain way to a magnetic field, is called a magnetic material, and can be divided into diamagnetic substances, paramagnetic substances, ferromagnetic substances, antiferromagnetic substances and ferrimagnetic substances according to the strength of magnetism of the substances in an external magnetic field, most of the materials are diamagnetic or paramagnetic substances which have weak reaction to the external magnetic field, the ferromagnetic substances and the ferrimagnetic substances are ferromagnetic substances, the magnetic material is generally called a ferromagnetic material, and for the magnetic material, a magnetization curve and a hysteresis loop are characteristic curves reflecting basic magnetic performance of the magnetic material. Ferromagnetic materials are typically Fe, Co, Ni elements and their alloys, rare earth elements and their alloys, and some Mn compounds.

The application provides a magnetic material fixing device, through using the magnet device, the magnetic material of fixed various shapes that can be convenient does not receive single shape magnetic material's restriction, during the use, only needs to put the magnetic material of survey on main platform 1, and magnetic material alright tightly attach no longer removes on main platform 1. After the magnetic material is broken on the universal testing machine, the device is manually butted together on the universal testing machine, and then the elongation after breakage of the magnetic material is measured.

In some embodiments, there are several magnet devices 3, and the several magnet devices 3 are uniformly arranged below the ground of the main platform 1.

In the embodiment of the application, a plurality of magnet devices 3 are arranged, which can ensure to provide enough magnetic attraction,

the uniform arrangement may provide a uniform magnetic field, and the number of magnet arrangements 3 here may be two, for example. Of course, in some embodiments, there may be more than two, and the position of the magnet device 3 may be specifically set according to the shape of the magnetic material.

In some embodiments, the magnet device 3 is an electromagnet.

In the embodiment of the application, the electromagnet is a device which generates electromagnetism when being electrified. An electrically conductive winding matched to the power of the core is wound on the outside of the core, and the coil, which is energized with current, has magnetic properties like a magnet, which is also called an electromagnet (electromagnet). It is usually made in the shape of a bar or a shoe to make the core easier to magnetize. In addition, in order to enable the electromagnet to be demagnetized immediately after being powered off, the electromagnet is often made of soft iron or silicon magnetic materials which are demagnetized quickly. When the electromagnet is electrified, the electromagnet has magnetism, and the magnetism disappears along with the electrification after the electromagnet is powered off. The electromagnet has wide application in daily life, and the power of the generator is greatly improved due to the invention of the electromagnet.

The working principle of the electromagnet is as follows: when the iron core is inserted inside the energized solenoid, the iron core is magnetized by the magnetic field of the energized solenoid. The magnetized core also becomes a magnet, so that the two magnetic fields are mutually superposed by the electromagnet, and the magnetism of the solenoid is greatly enhanced. In order to make the electromagnet more magnetic, the iron core is generally made into a shoe shape. However, it should be noted that the winding direction of the coil on the horseshoe is opposite, one side is clockwise, and the other side is counterclockwise. If the winding directions are the same, the magnetizing actions of the two coils on the iron core are mutually counteracted, so that the iron core does not show magnetism. In addition, the iron core of the electromagnet is made of soft iron, and cannot be made of steel. Otherwise, once the steel is magnetized, the magnetism of the steel can be kept for a long time and the steel cannot be demagnetized, and the strength of the magnetism of the steel cannot be controlled by the magnitude of the current, so that the advantages of the electromagnet are lost.

The electromagnet is a device which can generate magnetic force by passing current, belongs to a non-permanent magnet, and can easily start or eliminate the magnetism of the electromagnet. Illustratively, large cranes utilize electromagnets to lift the waste vehicle.

When an electric current is passed through the wire, a magnetic field is generated around the wire. By this property, a uniform magnetic field is created within the solenoid when a current is passed through the solenoid. If a ferromagnetic material is placed in the center of the solenoid, the ferromagnetic material is magnetized and the magnetic field is greatly enhanced.

Generally, the magnetic field generated by an electromagnet is related to the magnitude of the current, the number of turns of the coil, and the ferromagnetic body in the center. When designing electromagnets, the distribution of the coils and the selection of the ferromagnet are emphasized and the magnitude of the current is used to control the magnetic field. This limits the magnitude of the magnetic field that can be generated by the electromagnet due to the resistance of the coil material, but with the discovery and application of superconductors, there is an opportunity to exceed existing limitations.

The application provides a magnetic material fixing device for fixing device's magnetism is controllable through setting up the electro-magnet. When the device is used, a magnetic material to be measured is placed on the main platform 1, the magnetic material is tightly attached to the platform through the electromagnet and does not move any more, the elongation can be measured, and after the measurement is finished, the magnetic material is taken down.

In some embodiments, the magnetic material fixture further comprises: and the magnet switch 2 is electrically connected with the electromagnet.

In the embodiment of the present application, the magnetic switch 2 is a switch device that is induced by a magnet, the magnet switch 2 (magnetic proximity switch) is one of proximity switches, and the magnetic proximity switch is one of many types in a sensor family, is manufactured by an advanced process by using an electromagnetic working principle, and is a position sensor.

It can convert non-electric quantity or electromagnetic quantity into desired electric signal by means of the change of position relation between sensor and object so as to attain the goal of control or measurement.

The magnetic proximity switch can achieve the maximum detection distance with a small switch volume. It can detect a magnetic object (generally a permanent magnet) and then generate a trigger switch signal output.

Since magnetic fields can pass through many non-magnetic objects, the triggering process does not necessarily require the target object to be directly close to the sensing surface of the magnetic proximity switch, but rather the magnetic field is transmitted to a remote location through a magnetic conductor (such as iron), for example, a signal can be transmitted to the magnetic proximity switch through a high temperature to generate a triggering signal.

The application provides a magnetic material fixing device, during the use, put the magnetic material that needs the survey on main platform 1, open the magnet switch 3 of main platform 1 below, make magnetic material tightly attach no longer remove on the platform, alright carry out the measurement of elongation, the back of finishing the measurement, close the magnet switch, take off magnetic material can, set up magnet switch 3 and can more conveniently await measuring magnetic material get and put, avoid magnetic attraction too strong to main platform 1 to damage to some extent.
