Detailed Description

The present invention will now be described in more detail with reference to the accompanying drawings, and it is to be understood that the following description of the present invention is made only by way of illustration and not by way of limitation with reference to the accompanying drawings. The various embodiments may be combined with each other to form other embodiments not shown in the following description.

Example one

The embodiment provides a magnetic field heat treatment furnace, and aims to solve the problem that the shape and magnetism of a finished product discharged from the furnace are not in accordance with requirements due to the fact that a magnetic core 40 is sleeved on a horizontal sleeve pipe and is easy to deform in the magnetic field heat treatment process.

Referring to fig. 1 and 2, the magnetic field heat treatment furnace includes a furnace body 10 and a tray 20. Wherein, the furnace body 10 has a working chamber therein. The furnace body 10 is provided with a material delivery port for feeding/discharging material, and the material delivery port is communicated with the working chamber, so that the furnace body 10 is provided with a closed door for opening and closing the material delivery port.

The tray 20 is made of an insulating material and is disposed in the working chamber and used for placing the magnetic core 40. The specific connection relationship between the tray 20 and the furnace body 10 is not limited herein, as long as relative stability can be realized during the magnetic heat treatment process.

The bottom surface of the core 40 is referred to as a surface a401, and the top surface of the tray 20 is referred to as a surface b 201. When the tray 20 is fitted into the furnace shell 101, the surface b201 is horizontally arranged. Therefore, when the magnetic core 40 is placed on the tray 20, the surface a401 is attached to the surface b201, and the surface b201 surrounds the surface a401, so that the bottom surface of the magnetic core 40 has support.

It should be noted that, since the working chamber inside the furnace body 10 can be generally regarded as cylindrical, the tray 20 is preferably disposed in a cylindrical shape, and the axis of the tray 20 is disposed to coincide with the axis of the furnace body 10, so that the magnetic core 40 is as close to the axis of the furnace body 10 as possible when placed on the magnetic disk.

It should be noted that the shape of the magnetic core 40 is not limited herein, but the magnetic core 40 is preferably circular. When the magnetic cores 40 need to be subjected to batch heat treatment, the magnetic cores 40 are stacked along the axial direction, and an insulating spacer is arranged between the adjacent magnetic cores 40, which is not limited herein, as long as each magnetic core 40 is horizontal and the bottom surface has a supporting force.

In summary, since the thickness difference of the magnetic core 40 is small, that is, the thickness of the magnetic core 40 can be regarded as the same, when the magnetic core 40 is horizontally placed, the thickness direction of the magnetic core 40 is along the vertical direction, so that the magnetic core 40 is restrained from downwardly deforming under the support of the tray 20, thereby reducing the risk of deformation of the magnetic core 40 during the magnetic heat treatment process, and improving the yield of the finished product discharged from the furnace.

As an alternative solution, the area where the surface b201 and the surface a401 are attached is referred to as a contact area. For example, when the magnetic core 40 is annular and the tray 20 is cylindrical, the contact area is annular and the axis of the contact area coincides with the axis of the tray 20.

The tray 20 is provided with a through hole 202, and the through hole 202 is communicated with the contact area and the bottom surface of the tray 20. Therefore, when the temperature of the magnetic core 40 is increased or decreased, the temperature difference between the top surface and the bottom surface of the magnetic core 40 can be reduced, so as to reduce the probability of deformation of the magnetic core 40 due to temperature unevenness.

This through-hole 202 is preferred to be vertical setting to be convenient for the die sinking and mould plastics, with the degree of difficulty that reduces charging tray 20 production, thereby reduce overall cost. It should be noted that while the contact area is ensured to have the through holes 202, the through holes 202 may also be distributed outside the contact area, that is, the through holes 202 may be uniformly distributed on the surface b 201.

Example two

It should be noted that, in the conventional magnetic field heat treatment furnace, the side opening is usually provided, and then the worker feeds or discharges the magnetic core 40 laterally to fit the magnetic core 40 on the horizontal sleeve, so that the user needs to put the magnetic cores 40 into the furnace body 101 sequentially, but the feeding/discharging efficiency is low due to the limitation of the feeding port. The magnetic core 40 in the magnetic field heat treatment furnace of the embodiment is horizontally arranged, and the tray 20 is arranged on the base 102, so that during feeding, the magnetic core 40 to be subjected to magnetic field heat treatment can be arranged on the tray 20 in a matched manner, and then the base 102 is driven to move to a closed material conveying port, so that the magnetic core 40 enters the working cavity, and therefore the material conveying port is arranged at the bottom of the furnace body 101, and the feeding/discharging efficiency can be improved.

That is, the base 102 includes an upper portion and a lower portion, the upper portion can be inserted into the material delivery port, and the upper portion can be further provided with a power supply and/or a control circuit; the lower part cannot be inserted into the material conveying opening, but the edge of the lower part surrounds the edge of the material conveying opening so as to seal the material conveying opening.

This upper portion and lower part all can be cylindric and coaxial setting, and the preferred integrated into one piece of this upper portion and lower part provides the basis height for charging tray 20 on the one hand, and on the other hand has improved the leakproofness.

As an optional technical solution, the base 102 is fixed with a support frame 30, and the support frame 30 is located between the tray 20 and the base 102 to suspend the tray 20 relative to the base 102. And facilitates heating or cooling of the magnetic core 40. The support frame 30 may also be used in conjunction with the through hole 202 of the embodiment.

The transverse plates 301 of each group of supporting units are parallel and arranged at the same height so as to reduce the contact area between the supporting frame 30 and the material tray 20 and ensure the stability of the supporting frame 30 and the material tray 20.

It should be noted that the tray 20 may not be connected to the support frame 30, i.e. the tray 20 may be placed on the support frame 30 only. Of course, the tray 20 may be fixed to or integrated with the support frame 30 or may be detachable, which is not limited herein.

Preferably, the diameter of the tray 20 parallel to the horizontal plate 301 is taken as a reference line z, the diameter of the tray 20 perpendicular to the reference line z is taken as a reference line k, and all the vertical rods 302 are symmetrically distributed along the reference line z and the reference line k, so that the vertical rods 302 can be arranged in a row horizontally or in a row vertically, so as to facilitate cleaning of the support frame 30. Preferably, both ends of each horizontal plate 301 contact with the edge of the tray 20 or exceed the edge of the tray 20, so that the tray 20 is stably placed on the support frame 30.
