Description

Technical Field

[0001] The present application relates to the technical field of orientation magnetic field coils, and in particular to a water-cooled injection molding orientation magnetic field coil. Background Art

[0002] During the magnetization process, the magnetic material needs to be oriented by an orientation magnetic field coil so that a clear magnetic pole direction can be generated after the magnetic material is magnetized.

[0003] In the related technology, the injection molded orientation magnetic field coil includes a winding frame and a wire package. The wire package is wrapped around the circumference of the winding frame and electrically connected to an external power supply. When the power is turned on, the winding forms a certain magnetic field. When the magnetic material passes through the central magnetic field of the coil, the internal magnetic field will be affected by the external magnetic field, thereby completing the orientation of the magnetic material.

[0004] In the above-mentioned related technologies, when the magnetic field coil is performing orientation work, heat is generated after the current passes through the coil. When the heat is high, the coil will age, which is not conducive to improving the service life of the orientation magnetic field coil. Utility Model Content

[0005] In order to increase the service life of the orientation magnetic field coil, the present application provides a water-cooled injection molding orientation magnetic field coil.

[0006] The water-cooled injection molding orientation magnetic field coil provided in this application adopts the following technical solution:

[0007] A water-cooled injection molding orientation magnetic field coil, comprising:

[0008] The winding frame is arranged in a ring shape, and the winding frame is provided with a water cooling channel, and the water cooling channel is used for circulating cooling liquid;

[0009] A coil is disposed in the water cooling channel, the coil is radially wound along the winding frame, and the coil is connected to an external power source to generate a magnetic field.

[0010] By adopting the above technical solution, when the wire package is wrapped around the circumference of the winding skeleton and connected to an external power supply, a magnetic field can be generated to orient the magnetic material passing through the middle of the winding skeleton. At the same time, the coolant can circulate into the water cooling channel to absorb and dissipate the heat emitted by the wire package, making it difficult for the wire package to generate heat concentration, reducing the probability of aging of the wire package due to heat, and helping to extend the service life.

[0011] Optionally, an insulating baffle is also fixedly provided on the outer side wall of the winding frame.

[0012] By adopting the above technical solution, the setting of the insulating baffle plays an insulating and protective role, so that the peripheral side surface of the winding skeleton is not easy to conduct electricity when there is no contact, thereby improving the safety of use.

[0013] Optionally, the winding skeleton includes a winding bracket and a wiring end, the water cooling channel is radially opened along the axis of the winding bracket, the wiring end is fixedly connected to the winding skeleton, and the wiring end is provided with a water injection hole, which is connected to the water cooling channel.

[0014] By adopting the above technical solution, when the water cooling channel is opened radially along the axis of the winding bracket, the water injected from the water injection hole can flow radially, so that the heat transferred from the wire package to the winding frame can be circulated and dissipated.

[0015] Optionally, the water injection hole includes a first water injection hole and a second water injection hole, and the first water injection hole and the second water injection hole are arranged at intervals.

[0016] By adopting the above technical solution, the first water injection hole and the second water injection hole cooperate with each other, so that when the first water injection hole is injected with coolant, the coolant can automatically flow out from the second water injection hole under the action of the liquid pressure, thereby realizing the circulation of the coolant on the winding skeleton.

[0017] Optionally, the number of each of the first water injection hole and the second water injection hole is at least one.

[0018] By adopting the above technical solution, the provision of at least one water injection hole and a second water injection hole enables the circulating coolant to accelerate the flow rate entering and leaving the cooling channel, which helps to improve the cooling effect and further reduce the heat retained on the winding.

[0019] Optionally, a wiring terminal is fixedly provided on the surface of the winding bracket, the wiring terminal is connected to the wire package, and the wiring terminal extends toward a side away from the winding frame.

[0020] By adopting the above technical solution, the arrangement of the wiring terminals enables an electrical connection to be formed between the coil and the external power supply, and at the same time, when the wiring terminals are extended outward, it is convenient to connect to the external power supply.

[0021] Optionally, the winding wire of the coil is made of a hollow copper tube.

[0022] By adopting the above technical solution, when the hollow copper tube is used as a winding wire to make a wire package, since the copper tube material is relatively soft and has good electrical conductivity and heat-reducing properties, the wire package can be well wound and conductive, so as to generate a uniform magnetic field.

[0023] Optionally, the winding skeleton is made of hard metal material.

[0024] By adopting the above technical solution, when the winding skeleton is processed with hard metal material, the winding skeleton has a greater hardness, so it is not easy to bend during the winding process of the wire package, which helps to wind the wire package evenly.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The wire package is wrapped around the radial side of the winding frame and connected to an external power supply, which can generate a magnetic field to orient the magnetic material passing through the middle of the winding frame. At the same time, the coolant can circulate into the water cooling channel to absorb and dissipate the heat emitted by the wire package, making it difficult for the wire package to generate heat concentration, reducing the probability of aging of the wire package due to heat, and helping to extend the service life;

[0027] 2. The first water injection hole and the second water injection hole cooperate with each other, so that when the first water injection hole injects the coolant, the coolant can automatically flow out from the second water injection hole under the action of the liquid pressure, thereby realizing the circulation of the coolant on the winding frame; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses a water-cooled injection molding orientation magnetic field coil. Figure 1-3The water-cooled injection molding orientation magnetic field coil includes a winding skeleton 1 and a wire package 2. The winding skeleton 1 is provided with a water cooling channel 111 along the radial direction of the axis. The water cooling channel 111 is for the circulation of coolant. The wire package 2 is arranged in the water cooling channel 111 and is wound along the radial inner side of the winding skeleton 1. When the external power supply and the wire package 2 transmit current, the center of the axis of the winding skeleton 1 generates a magnetic field for affecting the magnetic material and completing the orientation. The coolant can continuously cool the heat dissipated by the wire package 2, so that it is not easy to cause heating and aging of the wire package 2, so as to extend the service life.

[0034] Reference Figure 1 and Figure 2 The winding frame 1 includes a winding support 11 and a wiring end 12. The winding support 11 is arranged in a rotating closed ring shape. The water cooling channel 111 is opened radially along the axis of the winding support 11. The wiring end 12 is provided with a water injection hole 121. The water injection hole 121 extends toward one side of the winding support 11, so that the water injection hole 121 and the water cooling channel 111 are connected, so that the external coolant can circulate into the water cooling channel 111 through the water injection hole 121. In order to make the winding frame 1 have better hardness, in this embodiment, the winding frame 1 is made of hard metal material, specifically, made of A3 steel.

[0035] Reference Figure 2 It should be further explained that the water injection hole 121 includes a first water injection hole 122 and a second water injection hole 123. The first water injection hole 122 and the second water injection hole 123 are arranged at intervals in the horizontal direction. The first water injection hole 122 is for the coolant to flow in, and the second water injection hole 123 is for the coolant to flow out, so as to realize the circulation of the coolant.

[0036] In addition, at least one of the first water injection holes 122 and the second water injection holes 123 is provided. In this embodiment, the number of the first water injection holes 122 and the second water injection holes 123 is introduced as an example of multiple first water injection holes 122 and multiple second water injection holes 123 are evenly arranged along the vertical direction. The multiple second water injection holes 123 are also evenly arranged along the vertical direction. By increasing the number of the first water injection holes 122 and the second water injection holes 123, the flow rate of the coolant during input and output can be increased, so that heat absorption can be effectively performed. The coolant can be water or other liquids that can absorb heat.

[0037] Reference Figure 1 and Figure 2 A wiring terminal 13 is fixedly provided on the side wall of the wiring end portion 12 away from the winding bracket 11. There are two wiring terminals 13, which are used as positive and negative poles for connecting an external power source. The two wiring terminals 13 are respectively connected to the two end side walls of the wire package 2 to facilitate the transfer of power to the wire package 2.

[0038] It should be further explained that the winding of the wire package 2 is a hollow copper tube, so that the winding of the wire package 2 is relatively soft as a whole, which is convenient for winding to form the wire package 2, and the copper material has good thermal conductivity and electrical conductivity, which is convenient for dissipating heat. Further, it should be explained that the external water flow is injected into the hollow chamber of the winding so that the water flow can directly pass through the wire package 2 and complete the cooling of the wire package 2.

[0039] Reference Figure 2 and Figure 3 The outer wall of the winding bracket 11 is also provided with an insulating baffle 3, and the shape and size of the insulating baffle 3 are consistent with the outer wall of the winding bracket 11. In this embodiment, the insulating baffle 3 is a bakelite board. In other embodiments, materials with the same insulating effect can also be used.

[0040] The implementation principle of a water-cooled injection molding orientation magnetic field coil in an embodiment of the present application is: by injecting coolant from the first water injection hole 122, the coolant passes through the hollow chamber of the wire package 2 and then circulates radially along the axis of the winding bracket 11, and is finally transmitted to the second water injection hole 123 to flow out, thereby dissipating the heat on the wire package 2, so that the wire package 2 is not easily aged due to poor heat dissipation, which helps to extend the service life.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
