Description
Technical Field
[0001] The utility model relates to the technical field of heat treatment, in particular to an induction through-heating device for large gear rings. Background Art
[0002] In industrial production, as a key transmission component, large gear rings are widely used in large-scale mechanical equipment, such as mining machinery, ship propulsion systems, and wind power generation equipment. The manufacturing quality of large gear rings directly affects the operating efficiency and service life of these equipment. Large gear rings are subjected to huge mechanical stresses and frictional forces in actual applications, requiring uniform hardness and wear resistance in all parts. Therefore, during the heat treatment process, it is necessary to ensure that the entire large gear ring is uniformly heated to avoid local overheating or underheating.
[0003] In the prior art, a through-heating furnace is usually used to heat-treat large gear rings. The through-heating furnace generates high temperature by burning fuel or electric heating elements and transfers the heat to the large gear ring.

Excessive energy consumption: The through-heating furnace generates high temperature by burning fuel or electric heating elements, and the entire heating process consumes a large amount of energy, resulting in high operating costs and an environmental burden. 2. Poor temperature uniformity: Since the heating method of the through-heating furnace is overall heating, it is difficult to achieve uniform heating inside and outside the large gear ring, resulting in inconsistent temperature distribution, thus affecting the heat treatment effect and product quality.

Detailed implementation manners
[0037] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0038] As Figure 1 shown, in combination with Figures 2-6 , an embodiment of the present utility model discloses a large gear ring induction heating equipment, including a slewing mechanism 1, an induction hardening mechanism 2 and a translation mechanism 3.
[0039] Among them, the slewing mechanism 1 is used to rotate the large gear ring S during the heating process, avoid the problem of uneven temperature caused by heating at a fixed position, make each part of the large gear ring S evenly heated, and improve the heat treatment effect.
[0040] The induction hardening mechanism 2 includes a first induction coil 21 and a second induction coil 22. The second induction coil 22 is coaxially sleeved outside the first induction coil 21, and there is a heating space 20 for accommodating the large gear ring S between the first induction coil 21 and the second induction coil 22. In this embodiment, induction coils are arranged on both the inner and outer sides of the large gear ring S, and the double induction coils are used to perform induction heating on both the inner and outer sides of the large gear ring S simultaneously, ensuring the temperature uniformity of the entire cross-section of the large gear ring S and avoiding the temperature gradient problem during the heating of the traditional through-heating furnace.
[0041] The translation mechanism 3 is used to drive the induction hardening mechanism 2 to move, so that the first induction coil 21 and the second induction coil 22 are coaxially sleeved on the inner and outer sides of the large gear ring S. In some embodiments, before the large gear ring S is installed on the rotary mechanism 1, the translation mechanism 3 drives the induction hardening mechanism 2 away from the rotary mechanism 1 to facilitate the feeding of the large gear ring S. After the large gear ring S is installed on the rotary mechanism 1, through the movement of the translation mechanism 3, the induction hardening equipment can flexibly adjust its position to ensure that the induction coil is coaxial with the large gear ring S, improving the stability and consistency of the heating effect.
[0042] The large gear ring S through-heating equipment disclosed by the present utility model realizes uniform heating of the inner and outer sides of the large gear ring S through the design of the double induction coils and in combination with the rotation function of the rotary device, avoiding the problem of uneven temperature caused by the traditional through-heating furnace and improving the heat treatment quality. The induction heating technology directly generates heat on the inner and outer sides of the large gear ring S through electromagnetic induction, reducing the transmission loss of energy, improving the energy efficiency, significantly reducing the energy consumption, and saving the production cost.
[0043] This embodiment shows a preferred structural form of the induction hardening mechanism 2. Specifically, referring to the attached Figure 2 and 3 as shown, the induction hardening mechanism 2 further includes a quenching transformer 23 and an electrical connection component 24.
[0044] Among them, the quenching transformer 23 provides the electric energy required for induction heating, and converts the input electric energy into the voltage and current suitable for the induction heating equipment through the quenching transformer 23.
[0045] The electrical connection component 24 is used to establish a current path between the induction hardening mechanism 2 and the first induction coil 21 and the second induction coil 22. Specifically, the electrical connection component 24 includes a first connection member 241, a second connection member 242, and a third connection member 243.
[0046] One end of the first connecting piece 241 is electrically connected to the positive terminal of the quenching transformer 23, and the other end of the first connecting piece 241 is electrically connected to the positive terminal of the second induction coil 22; the electric energy output by the transformer is transmitted to the positive terminal of the second induction coil 22 to ensure the current supply for induction heating. One end of the second connecting piece 242 is electrically connected to the negative terminal of the second induction coil 22, and the other end of the second connecting piece 242 is electrically connected to the positive terminal of the first induction coil 21; to realize the current flowing from the second induction coil 22 to the positive terminal of the first induction coil 21 to form a closed loop. One end of the third connecting piece 243 is electrically connected to the negative terminal of the first induction coil 21, and the other end of the third connecting piece 243 is electrically connected to the negative terminal of the quenching transformer 23. The current returns from the first induction coil 21 to the negative terminal of the quenching transformer 23 to form a complete current circulation path.
[0047] Through the electrical connections of the first connecting piece 241, the second connecting piece 242, and the third connecting piece 243, a series circuit is formed between the first induction coil 21 and the second induction coil 22, and the currents of the first induction coil 21 and the second induction coil 22 are the same, enabling the large gear ring S to obtain a uniform electromagnetic induction heating effect during the heat penetration process, further improving the uniformity of heat treatment.
[0048] To cool down the first induction coil 21 and the second induction coil 22, referring to the attached Figure 3 and 4 as shown, the present embodiment further provides a cooling assembly 25, and the cooling assembly 25 includes a first cooling plate 251, a second cooling plate 252, and a third cooling plate 253.
[0049] Among them, the first induction coil 21 and the second induction coil 22 are hollow inside. One end of the first cooling plate 251 is connected with a plurality of water inlet joints 2511, and the other end of the first cooling plate 251 is communicated with the positive terminal of the second induction coil 22, ensuring that the cooling water first enters the second induction coil 22 through the water inlet joints 2511 and the first cooling plate 251 for cooling. One end of the second cooling plate 252 is communicated with the negative terminal of the second induction coil 22, and the other end of the second connecting piece 242 is communicated with the positive terminal of the first induction coil 21, so that the cooling water inside the second induction coil 22 flows to the positive terminal of the first induction coil 21 to form a series cooling path. One end of the third cooling plate 253 is communicated with the negative terminal of the first induction coil 21, and the other end is provided with a plurality of water outlet joints 2531. Ensure that the cooling water is discharged smoothly through the third cooling plate 253 and the water outlet joints 2531 in the first induction coil 21 to complete the cooling cycle.
[0050] Through the first cooling plate 251, the second cooling plate 252 and the third cooling plate 253, cooling water flows in series inside the first induction coil 21 and the second induction coil 22 through the above cooling plates, timely taking away the heat generated when the induction coils work, keeping the equipment working within a safe temperature range, and improving the stability and service life of the induction heating equipment.
[0051] In order to enable the cooling assembly 25 and the electrical connection assembly 24 to form a series connection path between the first induction coil 21 and the second induction coil 22, the following technical solutions are adopted in this embodiment.
[0052] Specifically, a first notch 210 is provided on the first induction coil 21, and a second notch 220 is provided on the second induction coil 22. The settings of the first notch 210 and the second notch 220 facilitate the access of each connecting piece. In this embodiment, the end of the first connecting piece 241 away from the quenching transformer 23 is located in the second notch 220 and is electrically connected to the positive extreme of the second induction coil 22. One end of the second connecting piece 242 is located in the first notch 210 and is electrically connected to the positive extreme of the first induction coil 21. The other end of the second connecting piece 242 is electrically connected to the top surface of the negative extreme of the second induction coil 22. One end of the third connecting piece 243 is located in the first notch 210 and is electrically connected to the negative extreme of the first induction coil 21. The other end of the third connecting piece 243 is electrically connected to the negative extreme of the quenching transformer 23.
[0053] With this setting, the first connecting piece 241 is connected to the positive extreme of the second induction coil 22 through the second notch 220, the second connecting piece 242 is connected to the positive extreme of the first induction coil 21 through the first notch 210, and the third connecting piece 243 is connected to the negative extreme of the first induction coil 21 through the first notch 210, realizing the series flow of current in the first induction coil 21 and the second induction coil 22, and realizing the closing of the circuit and the circulation of current.
[0054] In this embodiment, the second cooling plate 252 is horizontally located on the top surfaces of the first induction coil 21 and the second induction coil 22, and is used to flow the coolant from the negative extreme of the second induction coil 22 to the positive extreme of the first induction coil 21. At the same time, the second cooling plate 252 is located on the top surface of the induction coil and does not occupy the heating space 20, facilitating the large gear ring S to enter the heating space 20.
[0055] The first insulating part G1 is located in the second notch 220 and is used to isolate the electrical components between the first connecting piece 241 and the second cooling plate 252, preventing short circuits and safety problems in the circuit; the second insulating part G2 is provided at the first notch 210 and is used to isolate the electrical components between the second connecting piece 242 and the third connecting piece 243, also to ensure the stable and safe operation of the circuit. It should be noted that the connecting pieces and the cooling plates are both made of conductive materials, preferably copper plates, with high heat dissipation intensity.
[0056] In some preferred embodiments, the electrical connection assembly 24 further includes a positive bus bar 244 and a negative bus bar 245. One end of the positive bus bar 244 is electrically connected to the positive terminal of the quenching transformer 23, and the other end is electrically connected to the first connector 241, which serves to collect and distribute current. One end of the negative bus bar 245 is electrically connected to the negative terminal of the quenching transformer 23, and the other end is electrically connected to the third connector 243, ensuring that the current can smoothly return to the transformer to achieve circuit closure.
[0057] Cooling pipelines L are provided on the side walls of both the positive bus bar 244 and the negative bus bar 245, which are used to carry away the heat generated by the bus bar during operation through the flow of coolant, keep it working within a suitable temperature range, and prevent overheating.
[0058] Since the first induction coil 21 and the second induction coil 22 are concentrically arranged, and the first induction coil 21 and the second induction coil 22 are connected through the electrical connection assembly 24 and the quenching transformer 23, and since the large gear ring S requires a larger diameter of the induction coil during the heating process, the overall load of the double induction coil and the electrical connection assembly 24 is relatively large, which will cause it to deform relative to the quenching transformer 23 during the heating process.
[0059] For this reason, the induction quenching mechanism 2 of this embodiment further includes a mounting frame 26, a hoisting frame 27 and fixing members 28. Refer to the appendix Figure 2 As shown, the quenching transformer 23 is fixedly arranged in the mounting frame 26, providing a stable basic structure to ensure that it does not move or deform during the heating process. The first induction coil 21, the second induction coil 22 and the electrical connection assembly 24 are located outside the mounting frame 26, which is convenient for cooperative heating with the large gear ring S. The translation mechanism 3 is fixedly connected to the mounting frame 26 and is used to drive the entire induction quenching mechanism 2 to translate.
[0060] One end of the hoisting frame 27 is fixedly connected to the mounting frame 26, and the other end is fixedly connected to the first induction coil 21 and the second induction coil 22 in the vertical direction. The setting of the hoisting frame 27 provides additional support to ensure the stability of the induction coil in the vertical direction, reduces the load of the induction coil and the electrical connection assembly 24, and prevents it from deforming relative to the quenching transformer 23.
[0061] There are multiple fixing members 28, which are evenly distributed outside the second induction coil 22 and are used to fix the relative positions of the first induction coil 21 and the second induction coil 22. The double induction coil is effectively prevented from deforming and shifting through the multi-point fixing method.
[0062] It should be noted that the hoisting frame 27 and the double induction coil are insulated from each other to avoid the risk of short circuit.
[0063] In order to realize the rotation of the large gear ring S during the heating process, this embodiment shows a structural form of the rotation mechanism 1. Specifically, refer to the attached Figure 5 As shown in the figure, the rotation mechanism 1 includes a rotating frame 11, a rotation motor 12 and a clamping fixture 13. The clamping fixture 13 is rotatably arranged on the top surface of the rotating frame 11, and the rotation motor 12 is fixedly arranged below the rotating frame 11 and is used to drive the clamping fixture 13 to rotate. The clamping fixture 13 is used for horizontally clamping and fixing the large gear ring S.
[0064] By driving the clamping fixture 13 with the rotation motor 12, the large gear ring S can rotate evenly, the heating is more uniform, and the processing accuracy and effect are improved. The clamping fixture 13 horizontally clamps and fixes the large gear ring S, ensuring that it will not shift or loosen during the rotation process, and improving the stability and reliability of the equipment. The rotation function of the clamping fixture 13 allows the large gear ring S to be exposed to the induction coil at multiple angles during the heating process, improving the uniformity and effect of heating.
[0065] As some embodiments, the clamping fixture 13 is a clamping chuck, which can be adjusted to adapt to the clamping and fixing of large gear rings S with different diameters.
[0066] As some preferred embodiments, there are several positioning members 131 for fixing the large gear ring S on the clamping fixture 13, and the positioning members 131 are made of heat-insulating materials. The use of heat-insulating materials effectively prevents the heat conduction and loss of the large gear ring S during the heating process, improves the heating efficiency and the safety of the equipment. At the same time, the application of heat-insulating materials reduces the influence of high temperature on other components of the equipment, such as the clamping fixture 13, reduces the thermal damage and potential safety hazards, and improves the overall safety of the equipment.
[0067] In order to realize the movement and adjustment of the induction hardening mechanism 2 by the translation mechanism 3, refer to the attached Figure 6 As shown in the figure, this embodiment shows a preferred structural form of the translation mechanism 3. Specifically, the translation mechanism 3 includes a support frame 31, a vertical frame 32, a first linear module 33, a second linear module 34 and a lifting module 35.
[0068] Among them, the induction hardening mechanism 2 is arranged above the support frame 31. The setting of the support frame 31 bears the induction hardening mechanism 2 and provides a stable support structure. The support frame 31 is located on one side of the vertical frame 32 and is slidably arranged on the vertical frame 32, allowing the support frame 31 to move in the height direction. The support frame 31 and the fixed frame are connected by the first linear module 33 and the second linear module 34. The first linear module 33 and the second linear module 34 are perpendicular to each other to ensure precise movement and adjustment in multiple directions. The vertical frame 32 is located on one side of the rotation mechanism 1, and the lifting module 35 is arranged on the vertical frame 32 and is used to drive the support frame 31 to move up and down along the height direction of the vertical frame 32 to realize the lifting adjustment of the induction hardening mechanism 2.
[0069] The perpendicular arrangement of the first linear module 33 and the second linear module 34 ensures the precise movement of the induction hardening mechanism 2 in the XY direction, guaranteeing high-precision positioning during the machining process. The use of the lifting module 35 enables the support frame 31 to move up and down along the height direction of the vertical frame 32, allowing the operator to conveniently adjust the height of the induction hardening mechanism 2 and simplifying the operation process.
[0070] The first linear module 33, the second linear module 34, and the lifting module 35 in this embodiment can be lead screw modules, and of course, they can also be other linear movement modules.
[0071] It should be noted that the support frame 31 is arranged on one side of the vertical frame 32 to enable the entire induction hardening mechanism 2 to translate along the height direction of the vertical frame 32. This is to avoid setting the lifting module 35 directly on the bottom surface of the induction hardening mechanism 2, which would occupy a large amount of space in the height direction. However, this would also cause some problems. For example, the entire load of the induction hardening mechanism 2, the support frame 31, the first linear module 33, and the second linear module 34 is all located on one side of the vertical frame 32. During the up and down movement, the above load will generate a lateral tilting moment relative to the vertical frame 32, resulting in unsmooth up and down movement or deformation of the vertical frame 32, thus preventing the effective cooperation between the double induction coil and the large gear ring S.
[0072] Therefore, the translation mechanism 3 of this embodiment further includes a counterweight assembly 36. The counterweight assembly 36 includes a pulley 361, a transmission member 362, and a counterweight 363. The pulley 361 is fixedly arranged at the top of the vertical frame 32. One end of the transmission member 362 is fixedly connected to the support frame 31, and the other end bypasses the pulley 361 and is fixedly connected to the counterweight 363.
[0073] With this setting, the introduction of the counterweight assembly 36, through the coordinated action of the pulley 361 and the counterweight 363, effectively balances the load on one side of the vertical frame 32, reduces the lateral tilting moment, and improves the stability and smoothness of the translation process. By reducing the influence of the lateral tilting moment on the vertical frame 32, it prevents the deformation of the vertical frame 32, protects the overall structure of the equipment, and improves the durability and reliability of the equipment.
[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
