[0030] Embodiment 1:

[0031] See also Figure 1 , Figure 2 The present embodiment discloses a rapid temperature rise and fall device capable of continuous production, comprising: a box-type furnace 2, wherein a furnace chamber 21 is arranged inside the box-type furnace; a workbench 1, wherein a second track 5 is arranged on the workbench; a first track 4, which has at least two groups, and a second running device 7 is arranged at the bottom thereof, and the second running device 7 can move the first track 4 along the direction of the second track 5; a sealed inner liner 3, which has the same number of groups as the first track 4, and a first running device 6 is arranged at the bottom of each sealed inner liner 3, and the first running device 6 can move the sealed inner liner 3 along the direction of the first track 4, so that the sealed inner liner 3 can be inserted into or pulled out of the furnace chamber 21.

[0032] In the production process of magnetic powder core products, it is sometimes necessary to conduct formula experiments. Through the control variable method, it can be known that when the formula is changed, other factors cannot be changed, such as atmosphere, temperature, etc. In addition, since the formula experiments are all small batches, it is not appropriate to use mass production kilns for formula experiments from the perspective of energy saving, so using box furnace 2 for formula experiments is a better choice. However, since the heating and cooling speeds of the existing box furnace 2 and the mass production kiln are inconsistent, it is necessary to improve the existing box furnace 2 to simulate the heating and cooling speeds of the mass production kiln as much as possible.

[0033] Specifically. The box-type furnace 2 of this embodiment can be a muffle furnace, and the box-type furnace 2 can be placed on the workbench 1 or not. In this embodiment, there are two sealed inner tanks 3, and the magnetic powder core product is placed in the sealed inner tanks 3. When the sealed inner tank 3 located in the furnace 21 is heated to a specified time, it is pulled out and quickly cooled outside the furnace 21. It can be cooled to a temperature below 200 degrees in a short time according to the requirements of the heat treatment curve to avoid oxidation problems when the product is out of the furnace, and then another sealed inner tank 3 is pushed into the furnace 21 to quickly heat up the magnetic powder core; the two sealed inner tanks 3 are used alternately to ensure that the magnetic powder core has a heating and cooling speed similar to that of a batch production kiln. In specific applications, the number of sealed inner tanks 3 can be designed according to the heating and cooling time.

[0034] In some alternative embodiments, see Figure 1 , Figure 2 , the two first rails 4 are a whole, and only one second running device 7 is provided at the bottom of the first rail 4, and the two first rails 4 move as a whole. In some other optional embodiments, the first rails 4 are split, and a second running device 7 (not shown in the figure) is provided at the bottom of each group of first rails 4, so that the movement of each group of first rails 4 can be controlled separately.

[0035] In some alternative embodiments, see Figure 1 , Figure 2, the direction of the first track 4 is the same as the depth direction of the furnace cavity, and the direction of the second track 5 is perpendicular to the direction of the first track 4. In some other optional embodiments, the second track 5 is circular or arc-shaped (not shown in the figure), and when the first track 4 moves along the direction of the second track 5 to the opening of the furnace 21, the direction of the first track 4 is the same as the depth direction of the furnace cavity.

[0036] See also Figure 1-Figure 3 , a limiting mechanism 8 is provided on the first track 4 and / or the second track 5, the limiting mechanism 8 on the first track 4 is used to limit the movement of the first running device 6, and the limiting mechanism 8 on the second track 5 is used to limit the movement of the second running device 7. Specifically, the limiting mechanism 8 is a pin 82 and a pin hole 81 provided on the first track 4 and / or the second track 5. When the sealed inner container 3 is inserted into the furnace 21, the first running device 6 is limited by the pin 82, which increases the stability of the system and prevents the sealed inner container 3 from being pulled out before being heated to the set time due to manual misoperation.

[0037] See also Figure 4 , Figure 5 , the sealed inner liner 3 includes: a liner body 31, a mounting frame 32 and a sealing door 33; the mounting frame 32 is welded or bolted to the liner body 31, and is welded or bolted to the first walking device 6. The sealing door 33 is hinged to one side of the liner body 31, or the sealing door 33 is locked to the liner body 31 by two or more locking bolts. The liner body 31 is also provided with an air inlet 311 and an air outlet 312 connected to an external protective gas source to provide a protective atmosphere for the sealed inner liner 3. Furthermore, the sealed inner liner 3 is made of stainless steel. It should be noted that whether to set the air inlet 311 and the air outlet 312 on the liner body 31 needs to be determined according to the category of the heated product. The magnetic powder core listed in this embodiment needs to be carried out under a protective atmosphere, so the air inlet 311 and the air outlet 312 are set. For other products that do not need to be heated and cooled under a protective atmosphere, the air inlet 311 and the air outlet 312 may not be set.

[0038] See also Figure 3 , Figure 4 , the first walking device 6 includes a first frame 61 and a first roller 62; the second walking device 7 includes a second frame 71 and a second roller 72; the first walking device 6 and the second walking device 7 are moved manually. In some other optional embodiments, the first walking device 6 also includes a first driving mechanism (not shown in the figure) for driving the first roller 62; the second walking device 7 also includes a second driving device (not shown in the figure) for driving the second roller 72; thus, the movement of the first walking device 6 and the second walking device 7 is controlled by the first driving mechanism and the second driving mechanism.

[0039] The device has at least two detachable sealed inner tanks 3. The alternate use of the sealed inner tanks 3 can ensure that the device has a similar heating and cooling speed as that of batch continuous production. When the product is cooled outside the furnace 21, the temperature of the box furnace 2 can be maintained, saving energy. A protective atmosphere can be provided during heat treatment to avoid oxidation problems of the product out of the furnace.

[0040] The above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the utility model.
