Accompanying drawing explanation
Fig. 1 is the structural representation of device of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, be described further, should be understood that the present embodiment is only for the technical solution of the utility model is described, and non-limiting the utility model.
Refer to Fig. 1, the structural representation that Fig. 1 is device of the present utility model.As shown in Figure 1, the device of the compressing rear surface of removal rare earth permanent magnet product of the present utility model Magnaglo comprises coil 1, iron core 2 and square box 3.Coil 1 is for generation of magnetic field, and iron core 2 is positioned at coil 1 center to improve the ability of device absorption Magnaglo, and coil 1 and the common formation of iron core 2 combination produce the device in magnetic field.Square box 3 is for sealing, support and install the combination of coil 1 and iron core 2, and the Magnaglo adsorbing while making its energising produce magnetic field stops outside at square box rather than is adsorbed on iron core after magnetizing.The size in the combination results magnetic field of coil 1 and iron core 2 is adjusted by regulating circuit 4.That is, regulating circuit 4 can be realized the magnetic field that regulates the size of input voltage and produce after coil is connected and change, thereby changes the ability of absorption Magnaglo.
Iron core 2 of the present utility model is made by the good soft magnetic materials of magnetic conductivity, as cast iron, silicon steel, permalloy etc.Wherein, the sectional area along producing magnetic direction of iron core 2 must not be less than the area of pre cleaning blank product face.
In addition, square box 3 of the present utility model is made by non-ferromagnetic material.Described non-ferromagnetic material can adopt aluminium alloy, magnetism-free stainless steel or bakelite plate, and bakelite plate selects thickness to be greater than the bakelite plate of 3mm.Particularly, the size of square box 3 can be held the combination of coil 1 and iron core 2 and can firmly fix coil 1 and the combination of iron core 2.After coil 1 is connected, regulating circuit 4 for regulate input voltage size so that the magnetic field that coil 1 produces after connecting change.
According to device of the present utility model, described device also comprises protection and turn on-switch circuit 5, and described protection and turn on-switch circuit 5 are realized closing coil and the parameters such as the turn-on current of coil and time are controlled, and make this device safe and reliable.Here, the on-off circuit of described protection and on-off circuit 5 adopts optoelectronic switch or position controlling switch.
When the utility model device is used, coil generation magnetic direction is vertical with pretreatment blank product surface, and the height of adjusting blank makes the center superposition of pretreating surface center and iron core 2.When moulding blank product is removed through this device, in coil 1, to connect and the magnetic field that changes, the Magnaglo that is attached to blank product surface can be adsorbed in the magnetic field of this variation, makes product surface light clean.After a large amount of minimizing of residual powder of product surface; the region that blank product separating device produces; closing coil 1 switch in switch and holding circuit 5 disconnects; in coil 1, no longer produce magnetic field, the Magnaglo that is before attracted to square box 3 surfaces is because gravity can drop in the device of collection residual powder of appointment.
In order to reach the effect of better removing blank product residue powder, can according to the size of product and remained on surface Magnaglo number, adjust in real time regulating circuit 4, this device is reached and knows to greatest extent powder, improve the presentation quality of product.Especially in the process of automatic material taking, can improve and remove powder effect according to how many sizes in regulating winding magnetic field neatly of the size of shaped article, remained on surface Magnaglo, use simple, efficient.
It should be noted that, above-mentioned utility model content and the specific embodiment are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the restriction to the utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, be equal to and replace or improve.Protection domain of the present utility model is as the criterion with appended claims.
