Description

Technical Field

[0001] The utility model relates to the technical field of annealing treatment, in particular to a two-dimensional soft magnetic powder activation annealing device. Background Art

[0002] Soft magnetic alloys are a type of alloys with high magnetic permeability and very low coercivity in weak magnetic fields. This type of alloy is widely used in radio electronics industry, precision instruments, remote control and automatic control systems. It is mainly used in energy conversion and information processing. It is an important material in the national economy. Soft magnetic alloy powders need to be activated and annealed when used. The soft magnetic alloy powders are placed in a heating furnace and heated to a certain temperature, and kept warm until the powder temperature cools naturally.

[0003] Prior art, such as publication number CN210789220U, provides a soft magnetic alloy powder activation annealing treatment device, including a furnace body, a sealing cover is installed at the top of the furnace body, a material injection port is installed at the top of the sealing cover, and the material injection port is located at one end of the top of the sealing cover, a water injection port is installed at the top of the sealing cover, and the water injection port is located at the other end of the top of the sealing cover, a transmission box is installed at the top of the sealing cover, and the transmission box is located in the middle of the top of the sealing cover, a connecting plate is installed at the top of the transmission box, and a motor is installed at the top of the connecting plate. A lifting ring is provided at the top of the shell of the utility model, and the utility model can be moved by the lifting ring. An alloy bar is provided on the inner side of the shell, and the alloy bar can be connected to the heating plate, so as to realize the continuous increase of the temperature inside the furnace body, and then the soft magnetic alloy powder in the furnace body is activated and annealed.

[0004] In this scheme, the blade is connected and rotated through the motor at the top of the shell, so as to stir the material in the furnace body, reduce the temperature difference inside the furnace body, and thus improve the temperature uniformity inside the furnace body. However, the heating tube in the heating furnace is generally only set on the furnace wall, and the problem of uneven heating occurs. This is mainly because the fast heating speed part is heat transferred through direct contact with the heat-conducting medium, and the heat transfer speed of the part that is not in direct contact is slow. During the stirring process, the position relationship between the inner and outer layers of the powder contacting the heat-conducting medium is difficult to change, resulting in the powder being unable to be directly heated, thereby affecting the heating efficiency. In view of this, we propose a two-dimensional soft magnetic powder activation annealing device. Utility Model Content

[0005] The purpose of the utility model is to provide a two-dimensional soft magnetic powder activation annealing device, which solves the problem that the positional relationship between the inner and outer layers of the powder contacting the heat-conducting medium during the stirring process is difficult to change, resulting in the powder being unable to be directly heated, thereby affecting the heating efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A two-dimensional soft magnetic powder activation annealing device comprises an annealing furnace body, wherein a rotating mechanism is arranged inside the annealing furnace body;

[0008] The rotating mechanism comprises a large turntable, which is rotatably connected to the back of the inner wall of the annealing furnace body through a rotating shaft, and a placement groove is provided on the front of the large turntable, and a heating barrel is embedded in the inner wall of the placement groove;

[0009] A driving mechanism is provided on the back side of the annealing furnace body for driving the large turntable to rotate. The large turntable is driven to rotate by the driving mechanism, and the heating barrel is driven to rotate by the rotation of the large turntable, so that the magnetic powder in the heating barrel rolls inside the heating barrel, and the positions of the inner and outer layers of the magnetic powder are converted during the rolling process of the magnetic powder, so as to avoid the problem that the magnetic powder in the inner layer cannot directly contact the barrel wall of the heating barrel, resulting in a slow heating speed and affecting the processing efficiency.

[0010] Preferably, a circle of extension plates is fixedly connected to the inner wall of the heating barrel, the number of the extension plates is six, and the two sides of the extension plates are arranged with inclined surfaces. By arranging the extension plates on the inner wall of the heating barrel, the area of ​​the inner wall of the heating barrel can be increased to increase the contact surface with the magnetic powder, and when the extension plates are rotated to a slightly inclined or horizontal position, the magnetic powder will be spread on the surface, further increasing the contact area to improve the efficiency of heat transfer.

[0011] Preferably, a barrel cover is connected to the front of the heating barrel, a lifting platform is provided below the heating barrel, and the lifting platform is fixedly connected to the bottom of the inner wall of the annealing furnace body. By providing a convenient lifting platform, a supporting force is provided to the heating barrel to facilitate the installation and disassembly of the heating barrel, thereby facilitating the addition or removal of materials.

[0012] Preferably, a circle of positioning blocks is fixedly connected to the back side of the outer wall of the heating barrel, and positioning grooves are provided on the inner wall of the placement groove at positions corresponding to the positioning blocks, and the positioning blocks are fixedly connected to the positioning grooves by bolts. By setting the positioning blocks to be clamped in the positioning grooves, the heating barrel can be easily positioned to improve the stability of the heating barrel during rotation.

[0013] Preferably, the driving mechanism includes a small turntable, which is arranged on the back of the annealing furnace body and fixedly connected to the large turntable through a rotating shaft. A cylinder is fixedly connected to the surface of the small turntable. A servo motor is fixedly connected to the back of the annealing furnace body through a mounting frame. A push rod is fixedly connected to the output end shaft of the servo motor, and the rotation path of the push rod is in contact with the cylinder.

[0014] Preferably, the number of the cylinders is six, which are arranged in a ring shape and evenly distributed, and correspond one to one with the positions of the extension plates. Since the push rod will only contact one of the cylinders during each rotation, the heating barrel connected to the large turntable rotates intermittently, so that the magnetic powder that is in direct contact with the heating barrel before each rotation can be fully heated and then turned over through subsequent rotations. The intermittent rotation method is more conducive to the heating of the magnetic powder.

[0015] Preferably, a friction block is provided on the outer wall of the small turntable, one side of the friction block is fixedly connected to a gas spring, and the gas spring is fixedly connected to the back side of the annealing furnace body through a support block. The tension of the gas spring is set to support the friction block to fit the outer wall of the small turntable, so that after the push rod leaves the cylinder, the small turntable will stop rotating due to the friction force, so as to facilitate heating.

[0016] By means of the above technical solution, the utility model provides a two-dimensional soft magnetic powder activation annealing device.

[0017] At least the following beneficial effects:

[0018] 1. The utility model drives the large turntable to rotate through a driving mechanism, and the rotation of the large turntable drives the heating barrel to rotate, so that the magnetic powder in the heating barrel rolls inside the heating barrel, and the position conversion of the inner and outer layers of magnetic powder is completed during the rolling process of the magnetic powder, so as to avoid the problem that the magnetic powder in the inner layer cannot directly contact the barrel wall of the heating barrel, resulting in a slow heating speed and affecting the processing efficiency. By arranging an extension plate on the inner wall of the heating barrel, the area of ​​the inner wall of the heating barrel can be increased to increase the contact surface with the magnetic powder. When the extension plate rotates to a slightly inclined or horizontal position, the magnetic powder will be spread on the surface, further increasing the contact area to improve the efficiency of heat transfer.

[0019] 2. In the utility model, since the push rod will only contact one of the cylinders during each rotation, the heating barrel connected to the large turntable can be rotated intermittently, so that the magnetic powder directly contacting the heating barrel before each rotation can be fully heated and then turned over through subsequent rotation. The intermittent rotation method is more conducive to the heating of the magnetic powder. BRIEF DESCRIPTION OF THE DRAWINGS

A circle of extension plates 232 are fixedly connected to the inner wall of the heating barrel 23, and the number of the extension plates 232 is six, and the two sides of the extension plates 232 are inclined. The extension plates are arranged on the inner wall of the heating barrel 23 The method of 232 can increase the area of ​​the inner wall of the heating barrel 23 to increase the contact surface with the magnetic powder, and when the extension plate 232 is rotated to a slightly inclined or horizontal position, the magnetic powder will be spread on the surface, further increasing the contact area to improve the efficiency of heat transfer. The front of the heating barrel 23 is connected to a barrel cover 233, and a lifting platform 24 is arranged below the heating barrel 23, and the lifting platform 24 is fixedly connected to the bottom of the inner wall of the annealing furnace body 1. By setting a convenient lifting platform 24, a supporting force is provided to the heating barrel 23 to facilitate the installation and disassembly of the heating barrel 23, and then to facilitate the addition or removal of materials. A circle of positioning blocks 231 is fixedly connected to the back of the outer wall of the heating barrel 23, and a positioning groove 221 is opened at the position of the positioning block 231 on the inner wall of the placement groove 22, and the positioning block 231 is fixedly connected to the positioning groove 221 by bolts. The positioning block 231 is arranged to be clamped in the positioning groove 221 to facilitate the positioning of the heating barrel 23 to improve the stability of the heating barrel 23 when rotating.

[0030] In this embodiment, a convenient lifting platform 24 is provided to provide a supporting force for the heating barrel 23, so as to facilitate the rotation of the bolts connecting the positioning block 231 and the positioning groove 221, thereby facilitating the disassembly of the heating barrel 23 for adding or removing materials. The large turntable 21 is driven to rotate by the driving mechanism 3, and the heating barrel 23 is driven to rotate by the rotation of the large turntable 21, so that the magnetic powder in the heating barrel 23 rolls inside the heating barrel 23, so that the position conversion of the inner and outer layers of the magnetic powder is completed during the rolling process of the magnetic powder, so as to avoid the problem that the magnetic powder in the inner layer cannot directly contact the barrel wall of the heating barrel 23, resulting in a slow heating speed and affecting the processing efficiency. In addition, by providing an extension plate 232 on the inner wall of the heating barrel 23, the area of ​​the inner wall of the heating barrel 23 can be increased to increase the contact surface with the magnetic powder. When the extension plate 232 rotates to a slightly inclined or horizontal position, the magnetic powder will be spread on the surface, further increasing the contact area to improve the efficiency of heat transfer.

[0031] Example 2

[0032] like Figure 5 As shown, the driving mechanism 3 includes a small turntable 31, which is arranged on the back of the annealing furnace body 1 and is fixedly connected to the large turntable 21 through a rotating shaft. A cylinder 32 is fixedly connected to the surface of the small turntable 31, and a servo motor 34 is fixedly connected to the back of the annealing furnace body 1 through a mounting frame 33. A push rod 35 is fixedly connected to the output shaft of the servo motor 34, and the rotation path of the push rod 35 contacts the cylinder 32. The push rod 35 is driven to rotate by starting the servo motor 34, so that the push rod 35 contacts the cylinder 32 during the rotation process, and the small turntable 31 is driven to rotate, thereby driving the large turntable 21 to rotate. There are six cylinders 32, which are arranged in a ring shape and are evenly distributed, and correspond to the positions of the extension plates 232 one by one. The push rod 35 will only contact one of the cylinders 32 during each rotation, so that the heating barrel 23 connected to the large turntable 21 rotates intermittently, so that the magnetic powder that is in direct contact with the heating barrel 23 before each rotation can be fully heated and then turned over through subsequent rotation. The intermittent rotation method is more conducive to the heating of the magnetic powder. A friction block 36 is fitted on the outer wall of the small turntable 31, and a gas spring 37 is fixedly connected to one side of the friction block 36, and the gas spring 37 is fixedly connected to the back side of the annealing furnace body 1 through a support block 38. The friction block 36 is supported by the tension of the gas spring 37 to fit the outer wall of the small turntable 31, so that after the push rod 35 leaves the cylinder 32, the small turntable 31 will stop rotating due to the action of friction to facilitate heating.

[0033] In this embodiment, the servo motor 34 is started to drive the push rod 35 to rotate, so that the push rod 35 contacts the cylinder 32 during rotation, which drives the small turntable 31 to rotate, and then drives the large turntable 21 to rotate. Since the push rod 35 will only contact one of the cylinders 32 during each rotation, the heating barrel 23 connected to the large turntable 21 rotates intermittently, so that the magnetic powder that is in direct contact with the heating barrel 23 before each rotation can be fully heated and then turned over through subsequent rotation. The intermittent rotation method is more conducive to the heating of the magnetic powder.

[0034] When the two-dimensional soft magnetic powder activation annealing device of the utility model is in use, a convenient lifting platform 24 is provided to provide a supporting force for the heating barrel 23, so as to facilitate the rotation of the bolts used for connecting the positioning block 231 and the positioning groove 221, thereby facilitating the disassembly of the heating barrel 23 for adding or removing materials. The large turntable 21 is driven to rotate by the driving mechanism 3, and the heating barrel 23 is driven to rotate by the rotation of the large turntable 21, so that the magnetic powder in the heating barrel 23 rolls inside the heating barrel 23, so that the position conversion of the inner and outer layers of the magnetic powder is completed during the rolling process of the magnetic powder, so as to avoid that the magnetic powder in the inner layer cannot directly contact The barrel wall of the heating barrel 23 causes a slow heating speed, which affects the processing efficiency. By setting an extension plate 232 on the inner wall of the heating barrel 23, the area of ​​the inner wall of the heating barrel 23 can be increased to increase the contact surface with the magnetic powder. When the extension plate 232 is rotated to a slightly inclined or horizontal position, the magnetic powder will be spread on the surface to further increase the contact area to improve the efficiency of heat transfer. By setting the tension of the gas spring 37 to support the friction block 36 to fit the outer wall of the small turntable 31, the small turntable 31 will stop rotating due to the friction force after the push rod 35 leaves the cylinder 32.
