Description

TECHNICAL FIELD

[0001] The application relates to the technical field of transverse magnetic furnace heat treatment, and in particular to a transverse tooling clamp for transverse magnetic furnace heat treatment. BACKGROUND

[0002] At present, the conventional furnace loading of a horizontal furnace is to push magnetic cores strung on rods into a horizontal furnace with the magnetic field direction parallel to the ground to perform transverse magnetic field heat treatment. Generally, the magnetic cores with tooling clamps cannot be directly used, and need to be subjected to sizing annealing to keep the shape of the magnetic cores and then the clamps are removed to pass through the rods.

[0003] The process of annealing and magnetic pulling integrated heat treatment with the clamps needs to vertically stack the magnetic cores layer by layer, and then hoist into a vertical furnace perpendicular to the ground to perform heat treatment. This stacking mode can load the racetrack-shaped and rectangular magnetic cores with tooling clamps.

[0004] In the related art, compared with the horizontal furnace, the stacking procedure of using the vertical furnace is relatively cumbersome, and the furnace body is far less convenient to enter and exit than the horizontal furnace.

[0005] Therefore, it is urgent to design a tooling clamp capable of transversely arranging the magnetic cores, which is suitable for loading into the horizontal furnace to perform heat treatment, so that the horizontal furnace can also perform integrated annealing and magnetic field heat treatment of the magnetic cores with tooling clamps, and the application range of the horizontal furnace is expanded.

[0010] Further, the bottom plate and the side plates are in rectangular structures, and the clamp sleeves are in a back-to-back structure.

[0011] Further, the sum of the thickness of the two side plates and the width of the bottom plate is equal to the length of the inner side of the clamp sleeve.

[0012] Further, the width of the side plate is consistent with the inner side length of the clamp assembly.

[0016] Further, the top and bottom of the two side plates are provided with stable positioning grooves, and the top and bottom of the inner side of the clamp assembly are symmetrically provided with stable positioning blocks matched with the stable positioning grooves.

[0017] Further, the two outer sides of the bottom plate are symmetrically provided with splicing stable strips, and the side corresponding to the two side plates is provided with a splicing stable groove matched with the splicing stable strip.

[0018] Compared with the prior art, the beneficial effects of the present application are:

[0019] By setting the bottom plate, the side plate and the clamp assembly to be mutually spliced and assembled to form a horizontal tooling clamp, the magnetic core can be directly placed into the assembled clamp assembly body, so as to adapt to the horizontal tooling clamp with the magnetic core placed therein being loaded into a horizontal furnace for heat treatment, so that the horizontal furnace can also perform integrated annealing magnetic field heat treatment with the tooling clamp magnetic core, and the placing process is relatively simple, and the furnace body is convenient and fast.

[0020] In addition, in order to make the nanocrystalline magnetic core receive sufficient magnetic field induction in the magnetic field heat treatment, the magnetic cores need to be closely arranged axially to form a magnetic circuit with sufficient length; therefore, the horizontal tooling clamp arrangement of the present application can meet the requirement that the magnetic cores are connected head to tail to form a magnetic circuit, and can be conveniently placed into the horizontal furnace cavity, so that it can be subjected to integrated annealing magnetic field heat treatment with the tooling, and has applicability to integrated magnetic field of runway type, rectangular and other special-shaped magnetic cores, and further does not need to be first tooling and annealed before being loaded into the furnace through the rod, so as to improve the production efficiency.

[0027] The following will be described in detail below with reference to the accompanying Figures 1-4 The present application will be further described in detail.

[0028] An embodiment of the present application discloses a transverse work fixture clamp which can be used for transverse magnetic furnace heat treatment, referring to Figure 1 and Figure 2 In the embodiment, the transverse work fixture clamp comprises a bottom plate 1, side plates 2 and a clamp assembly 3. The bottom plate 1 is a long plate strip in a rectangular structure, and is placed horizontally when assembled. The side plates 2 are provided in two pieces, both of which are long plate strips in a rectangular structure. The two side plates 2 are placed on both sides of the bottom plate 1, and the bottoms of the two side plates 2 are aligned with the bottom of the bottom plate 1, and the end faces of the two side plates 2 are aligned with the end faces of the bottom plate 1.

[0029] Preferably, in the embodiment, a plurality of bottom plate holes 5 are also provided on the bottom plate 1. The main purpose of the bottom plate holes 5 is to reduce the weight of the overall clamp and increase the contact area with the external atmosphere, thereby accelerating the heating and cooling speed during heat treatment.

[0030] In this way, the two side plates 2 and the bottom plate 1 form a clamp assembly body therebetween, and the clamp assembly body is provided with a clamping slot hole 6. The clamping slot hole 6 cooperates with the magnetic core 4, so that the magnetic core 4 can be directly placed into the clamp assembly body, and the magnetic core 4 can maintain its shape.

[0031] Meanwhile, in the embodiment, a plurality of clamp assemblies 3 are provided, and each of the plurality of clamp assemblies 3 is in a back-shaped structure. The back-shaped clamp assemblies 3 are respectively sleeved on the outer side of the clamp assembly body, so as to stably position the two side plates 2 and the bottom plate 1, thereby completing the assembly of the transverse work fixture clamp. In addition, when the clamp assemblies 3 are sleeved on the outer side of the clamp assembly body, the clamp assemblies 3 can also effectively stably bear the entire transverse work fixture clamp.

[0032] Specifically, referring to Figure 1 and Figure 2In the embodiment, the three clamp assemblies 3 are arranged at the outer front end, the outer middle end and the outer rear end of the clamp assembly body respectively, so as to achieve the effect of stably limiting the clamp assembly body, thereby facilitating the stable placement of the magnetic core 4.

[0033] More specifically, the sum of the thickness of the two side plates 2 and the width of the bottom plate 1 is equal to the inner length of the clamp assembly 3, so that the two outer sides of the clamp assembly body are matched with the two inner sides of the clamp assembly 3 respectively; at the same time, the width of the side plate 2 is consistent with the inner width of the clamp assembly 3, so that the top of the two side plates 2 is matched with the inner top of the clamp assembly 3 at the same time, and the bottom of the two side plates 2 and the bottom of the bottom plate 1 are matched with the inner bottom of the clamp assembly 3 respectively.

[0034] In this way, the clamp assemblies 3 constrain the degrees of freedom of the clamp assembly body by means of the contact surface and friction, so as to achieve the effect of stably limiting the clamp assembly body, thereby preventing the side plates 2 and the bottom plate 1 from being scattered, and further completing the assembly of the horizontal tooling clamp. At the same time, when disassembling the horizontal tooling clamp, the clamp assemblies 3 are only needed to be slid out of the clamp assembly body one by one, so as to achieve the disassembly of the clamp assembly body.

[0035] In addition, in order to enable the nanocrystalline magnetic core 4 to be subjected to sufficient magnetic field induction in the magnetic field heat treatment, it is necessary to arrange the magnetic cores 4 in an axial direction to form a magnetic path with sufficient length. In the embodiment, the clamp assembly bodies on the same straight line are connected end to end to form a magnetic path, so as to ensure the length of the magnetic path.

[0036] Specifically, the plurality of assembled horizontal tooling clamps are arranged on the same straight line and connected end to end, so that the clamping grooves 6 of the clamp assembly bodies are connected to form a magnetic path capable of placing a plurality of magnetic cores 4, thereby enabling the magnetic cores 4 to be connected end to end.

[0037] In this way, the arranged horizontal tooling clamps can be conveniently placed into the furnace cavity of the horizontal furnace, so that the magnetic field heat treatment of the integrated annealing with tooling can be performed, and the integrated magnetic pulling of the runway-shaped, rectangular and other special-shaped magnetic cores 4 is applicable, thereby eliminating the need for tooling and shaping annealing before the rod is inserted into the furnace, and the production efficiency is improved.

[0038] Therefore, by arranging the bottom plate 1, the side plates 2 and the clamp assemblies 3 to be assembled and connected to form the horizontal tooling clamp, the magnetic core 4 can be directly placed into the assembled clamp assembly body, so as to be suitable for loading the horizontal tooling clamp with the magnetic core 4 into the horizontal furnace for heat treatment, thereby enabling the horizontal furnace to perform the integrated annealing magnetic field heat treatment of the magnetic core 4 with the tooling clamp, and further enabling the placement process to be simple, and the furnace body to be convenient and fast.

[0039] Secondly, in order to improve the stability between the side plate 2 and the clamp sleeve 3. Therefore, referring to Figure 3 and Figure 4 In another embodiment, the top and bottom of the two side plates 2 are provided with stable positioning slot holes 7, and the top and bottom of the inner side of the clamp sleeve 3 are symmetrically provided with stable positioning blocks 8, which are respectively matched with the stable positioning slot holes 7.

[0040] In this way, by setting the structure of the stable positioning block 8 and the stable positioning slot hole 7 matched with each other, not only can the clamp sleeve 3 be effectively guided and positioned, so that the clamp sleeve 3 can be sleeved on the outside of the clamp assembly along the stable positioning slot hole 7; but also can effectively position the side plate 2, thereby preventing the side plate 2 from being offset or even scattered, and further improving the stability between the side plate 2 and the clamp sleeve 3.

[0041] At the same time, in order to improve the stability between the bottom plate 1 and the two side plates 2. Therefore, referring to Figure 4 In another embodiment, the two outer sides of the bottom plate 1 are symmetrically provided with splicing stability bars 9, and the bottom ends of the two side plates 2 correspondingly are provided with splicing stability grooves 10, which are matched with the splicing stability bars 9, so that the splicing stability bars 9 are stably inserted into the splicing stability grooves 10.

[0042] In this way, by setting the structure of the splicing stability groove 10 and the splicing stability bar 9 matched with each other, not only can the two side plates 2 be stably spliced and installed on the two sides of the bottom plate 1, thereby realizing the effect of quick assembly; but also can effectively guide and limit, thereby preventing the side plate 2 and the bottom plate 1 from being offset during assembly.

[0043] In addition, in the actual operation process, in view of the pain point that the horizontal furnace is not convenient to perform the runway type magnetic core integrated annealing magnetic field heat treatment with the tool clamp; in the embodiment, the transverse tool clamp design optimized by the application expands the applicable process of the horizontal furnace. In this way, the comparison of the appearance of the magnetic core 4 prepared by the transverse tool clamp of the horizontal furnace and the conventional two-step heat treatment process can be made, and it can be concluded that the size of the magnetic core 4 prepared by the transverse tool clamp of the application still meets the requirements.

[0044] At the same time, the following table is the 100kH single-turn inductance comparison of the magnetic core 4 prepared by the transverse tool clamp of the horizontal furnace and the conventional two-step heat treatment process; from the data in the table, it can be seen that the performance of the magnetic core 4 prepared by the transverse tool clamp is consistent with that of the conventional process.

[0046] The implementation principle of the transverse tool clamp for horizontal magnetic furnace heat treatment in the embodiment of the application is:

[0047] First according to the size requirements design tool fixture;Then the tool fixture drawings, standards and tolerance and to the relevant mechanical and electrical departments for production;Again the bottom plate 1, side plate 2 and fixture set 3 are made respectively, to splice assembly into horizontal tool fixture;Then the magnetic core 4 is placed into the inside of horizontal tool fixture, to clamp the magnetic core 4 into the shape required by the product;At the same time, a plurality of horizontal tool fixtures are connected head to tail, to be placed on the furnace car, to ensure the magnetic path length;Then the magnetic core 4 placed in the horizontal tool fixture is annealed and transverse magnetic field heat treated as much as possible;Finally, the magnetic core 4 after transverse magnetic heat treatment can be normally transferred to the subsequent assembly, detection, packaging and delivery processes.
