Description

Technical Field

[0001] This utility model relates to the field of quenching equipment technology, specifically a combined induction quenching machine tool. Background Technology

[0002] A quenching machine tool is a specialized piece of equipment that uses induction heating to perform surface or localized quenching treatment on metal workpieces. Based on layout, it can be divided into vertical and horizontal types, and is mainly used in the heat treatment processes of mechanical parts such as gears, bearings, and shafts. It consists of a bed, slide table, clamping and rotating mechanism, cooling system, quenching fluid circulation system, and electrical control system, among other systems and mechanisms. Customized models can be provided according to the workpiece shape. Widely used in the machinery manufacturing field, it enables efficient and precise quenching of workpieces.

[0003] Existing modular induction hardening machine tools have significant drawbacks in use. During the hardening process, the heat radiation generated by heating and the heat transfer from the evaporation of the hardening fluid cause the machine tool door temperature to rise. Currently, the door handles are mostly made of stainless steel or aluminum alloy, materials with high thermal conductivity. Heat is easily transferred from the door to the handle, posing a risk of burns to workers when opening and closing the door. More seriously, when the workpiece surface is covered with residual oil, cutting fluid, rust-preventive oil, or contaminated with flammable materials such as cloth or paper scraps, the high temperature generated during hardening is sufficient to reach its ignition point and ignite it. The flames directly contacting the door further exacerbate the temperature rise of the handle. If a worker is burned by touching the handle, their instinctive reaction will be to withdraw their hand, requiring them to search for towels, gloves, or other heat-resistant items. This not only affects normal operating efficiency but may also delay emergency response such as fire extinguishing, posing a dual risk to both safety and efficiency. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a combined induction hardening machine tool to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a combined induction hardening machine tool, comprising a combined induction hardening machine tool body, a door connected to the outer surface of the combined induction hardening machine tool body, and an installation plate connected to one side of the outer surface of the door, a bracket fixed to the outer surface of the installation plate, and a filling layer provided inside the bracket, a thermal break insulation sleeve penetrating the outer surface of the bracket, and a handle penetrating one end of the thermal break insulation sleeve.

[0006] By adopting the above technical solution, a multi-level heat insulation and conduction structure from the door body to the handle is constructed. By utilizing the synergistic effect of the mounting plate, bracket, filling layer, and thermal break insulation sleeve, multiple barriers to heat transfer are formed, thereby reducing the transfer of heat from the door body to the handle and reducing the risk of the handle getting too hot.

[0007] Furthermore, the bracket has a double "Y" shaped cross-section, and the mounting plate is fixedly connected to the bracket by welding.

[0008] By adopting the above technical solution, the double Y-shaped structure extends the heat conduction path between the door and the handle, while increasing the contact area with the external airflow to facilitate heat dissipation; the welding and fixing method ensures that the mounting plate and the bracket are firmly connected, avoiding deformation of the heat insulation structure due to loosening, and maintaining the stability of heat transfer barrier.

[0009] Furthermore, the thermal break insulation sleeve is made of mica-reinforced phenolic resin composite material, and the cross-section of the thermal break insulation sleeve is "T" shaped.

[0010] By adopting the above technical solution, the mica-reinforced phenolic resin composite material has a high thermal resistance value, which can effectively slow down heat conduction. The T-shaped cross-section structure can enhance the physical isolation effect between the bracket and the handle, break the thermal bridge between the two, and reduce the transfer of heat from the bracket to the handle.

[0011] Furthermore, both the handle and the bracket are made of 316 stainless steel.

[0012] By adopting the above technical solutions, 316 stainless steel has good corrosion resistance, which can reduce the corrosive effect of workers' sweat on the parts. At the same time, its thermal conductivity is at a medium-low level among metals, which can slow down the heat transfer rate and reduce the heat accumulation in the handles and brackets.

[0013] Furthermore, the support is hollow inside, and the filling layer is phenolic foam.

[0014] By adopting the above technical solutions, the hollow design inside the bracket reduces the heat-conducting cross-sectional area and lowers the heat transfer efficiency; the phenolic foam filling layer is heat-resistant and flame-retardant, which can reduce the convection of air inside the bracket caused by thermal expansion and contraction, avoid air flow from enhancing heat transfer, and enhance the overall heat insulation effect of the bracket.

[0015] Furthermore, the mounting plate has multiple through holes on its back.

[0016] By adopting the above technical solution, the through hole facilitates the disassembly and connection of the mounting plate to the door body with bolts, ensuring the installation stability of the overall structure; at the same time, the mounting plate forms a seal on the back of the bracket, which can prevent the filling layer from leaking out when filling phenolic foam, ensuring the integrity of the filling to maintain the heat insulation effect.

[0017] Furthermore, a controller is installed on one side of the outer surface of the main body of the combined induction hardening machine tool.

[0018] By adopting the above technical solution, the controller can accurately control key parameters of the machine tool such as induction heating power, heating time, and quenching fluid circulation, thereby realizing automated management of the quenching process and ensuring the stability and accuracy of workpiece quenching.

[0019] Furthermore, the outer ring of the handle has multiple arc-shaped grooves, and the thermal break sleeve is fixedly connected to the handle and the grooves by molding inserts.

[0020] By adopting the above technical solution, the connection method of the arc-shaped groove and the molded insert can enhance the tightness of the connection between the thermal break sleeve and the handle, avoid the impact of loose connection on the stability of the thermal insulation structure, and ensure the continuous performance of the thermal insulation effect.

[0021] Furthermore, the thermal break insulation sleeve is connected to the bracket by bolts, and the thermal break insulation sleeve is detachably connected to the bracket via bolts.

[0022] By adopting the above technical solution, the detachable structure with bolted connection makes it easy to disassemble and replace when the thermal break insulation sleeve or bracket is damaged. After replacement, the original thermal insulation structure and connection method can still be maintained, ensuring long-term stable operation of the equipment and reducing the possibility of hot handles.

[0023] In summary, the present invention has the following main advantages:

[0024] 1. This utility model, through the setting of the bracket, has a double Y-shaped curved structure in its cross section, which extends the heat conduction path between the door and the handle, and at the same time increases the contact area with the external airflow to facilitate heat dissipation; the internal hollow design reduces the heat conduction cross-sectional area and reduces the heat transfer rate; and it is made of 316 stainless steel, which is not only resistant to corrosion from workers' sweat, but also has a low to medium thermal conductivity among metals, which can effectively slow down the transfer of heat from the door to the handle, reducing heat accumulation in the handle from multiple dimensions.

[0025] 2. This utility model uses a thermal break sleeve made of mica-reinforced phenolic resin composite material. Phenolic resin itself has a high thermal resistance and good mechanical strength. After being reinforced by mica, the thermal resistance is further improved. The T-shaped cross section can physically isolate the bracket and the handle, breaking the thermal bridge between them, thereby reducing the transfer of heat from the bracket to the handle and reducing the temperature rise of the handle.

[0026] 3. This utility model, through the setting of a filling layer and a mounting plate, uses phenolic foam as the filling layer, which is heat-resistant and flame-retardant. It fills the hollow area inside the bracket, which can reduce the convection caused by thermal expansion and contraction of air inside the bracket, avoid air flow that enhances heat transfer, and enhance the overall heat insulation effect of the bracket. The mounting plate has multiple through holes on the back, which facilitates the fixed connection with the door body by bolts. At the same time, it seals the back of the bracket to prevent the filling layer from leaking out when filling with phenolic foam, ensuring the integrity of the filling, thereby ensuring the stable performance of the heat insulation effect and reducing the occurrence of hot handles.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A combined induction hardening machine tool, such as Figures 1-5As shown, the machine includes a main body 1 of a modular induction hardening machine tool. A door 3 is connected to the outer surface of the main body 1. A mounting plate 9 is connected to one side of the outer surface of the door 3. Multiple through holes are opened on the back of the mounting plate 9. A bracket 5 is fixed to the outer surface of the mounting plate 9. The bracket 5 has a double "Y" shaped cross-section. The mounting plate 9 is fixedly connected to the bracket 5 by welding. The bracket 5, as a key component connecting the mounting plate 9 and the handle 4, extends the heat conduction path when heat is transferred from the mounting plate 9 to the handle 4 due to its double "Y" shaped bending structure. It also increases the contact area with the external airflow, facilitating heat dissipation through airflow. The hollow internal design reduces the thermal conductivity cross-sectional area and lowers the heat transfer rate. The 316 stainless steel material, with its low to medium thermal conductivity among metals, further slows down heat transfer and resists corrosion from sweat during worker contact, maintaining structural stability. The bracket 5 is hollow inside. The bracket 5 has an internal filling layer 8, which is phenolic foam. This phenolic foam fills the hollow area inside the bracket 5. Its heat-resistant and flame-retardant properties reduce convection caused by thermal expansion and contraction of air inside the bracket 5, preventing increased heat transfer due to airflow and thus enhancing the overall insulation effect of the bracket 5. A thermally broken insulation sleeve 6 penetrates the outer surface of the bracket 5. The thermally broken insulation sleeve 6 is made of mica-reinforced phenolic resin composite material. The cross-section of the thermally broken insulation sleeve 6 is T-shaped, and a handle 4 penetrates one end of the thermally broken insulation sleeve 6. Both the handle 4 and the bracket 5 are made of 316 stainless steel. The thermally broken insulation sleeve 6 is made of mica-reinforced phenolic resin composite material. Phenolic resin itself has high thermal resistance and good mechanical strength. After being reinforced with mica, the thermal resistance is further improved. Its T-shaped cross-section structure can physically isolate the bracket 5 from the handle 4, breaking the thermal bridge between them and reducing the transfer of heat from the bracket 5 to the handle 4.

[0037] See Figure 1 In the above embodiment, a controller 2 is installed on one side of the outer surface of the main body 1 of the combined induction hardening machine tool. The main body 1 of the combined induction hardening machine tool is equipped with a clamping and rotating mechanism, a cooling system, a quenching liquid circulation system, etc. The main body 1 of the combined induction hardening machine tool serves as the basic load-bearing structure. The controller 2 is used to regulate the overall quenching process. The operator controls the opening and closing of the door 3 through the handle 4 to facilitate the picking up and placing of the workpiece and the protection during processing. During processing, the workpiece is clamped by the clamping and rotating mechanism inside the machine tool. The controller 2 regulates the power, frequency and heating time of the induction heating component. The induction coil generates eddy currents on the surface or in a localized area of ​​the workpiece through electromagnetic induction, causing the target area of ​​the workpiece to heat up rapidly. When the workpiece reaches the predetermined heating temperature, the cooling system and the quenching liquid circulation system are immediately activated. After being filtered and cooled by the circulation system, the quenching liquid is rapidly sprayed onto the high-temperature area of ​​the workpiece through the nozzle, using the strong cooling capacity of the quenching liquid to instantly cool the surface of the workpiece.

[0038] Example 2:

[0039] Based on the above embodiment one, the following settings are now adopted to increase the stability of the structural connection.

[0040] See Figure 3 and Figure 4 In the above embodiment, the outer ring of the handle 4 is provided with multiple arc-shaped grooves. The thermal break insulation sleeve 6 is formed by molding and fixedly connected to the handle 4 and the grooves. The multiple arc-shaped grooves on the outer ring of the handle 4 and the mica-reinforced phenolic resin composite material are formed by molding and fixedly connected to the handle 4 and the thermal break insulation sleeve 6 through molding and inserting. This connection method makes the thermal break insulation sleeve 6 and the handle 4 tightly combined.

[0041] Example 3:

[0042] Based on the above embodiment one, the following settings are now implemented to facilitate the replacement of damaged structures.

[0043] See Figures 2-5 In the above embodiment, the thermal break insulation sleeve 6 and the bracket 5 are connected by bolts 7. The thermal break insulation sleeve 6 is detachably connected to the bracket 5 through bolts 7. This detachable structure allows the thermal break insulation sleeve 6 or the bracket 5 to be easily disassembled and replaced when it is damaged due to long-term use. After replacement, the original thermal insulation structure and connection method can still be maintained, ensuring that the equipment continuously and stably reduces the hot handle 4.

[0044] The implementation principle of this utility model is as follows: First, during production, multiple arc-shaped grooves on the outer ring of the handle 4 are molded with mica-reinforced phenolic resin composite material through molding inserts to form a fixed connection between the handle 4 and the thermal break sleeve 6. This connection method ensures that the thermal break sleeve 6 and the handle 4 are tightly combined, preventing relative movement between the two during use from affecting the stability of the thermal insulation structure and ensuring the continuous performance of the thermal insulation effect. The worker welds the mounting plate 9 to the back of the bracket 5. This is to facilitate the subsequent connection of the mounting plate 9 to the door body 3 with bolts, and to prevent the phenolic foam from leaking out from the back of the bracket 5 when filling it with phenolic foam. After the phenolic foam is filled, the worker connects the thermal break sleeve 6 and the bracket 5 with bolts. This detachable structure allows for easy disassembly and replacement when the thermal break sleeve 6 or the bracket 5 is damaged due to long-term use. After replacement, the original thermal insulation structure and connection method are maintained, ensuring that the equipment continues to stably reduce the hotness of the handle 4.

[0045] The main body 1 of the combined induction hardening machine tool serves as the basic load-bearing structure. The controller 2 is used to regulate the overall hardening process. The operator controls the opening and closing of the door 3 through the handle 4 to facilitate the handling and protection of the workpiece. During processing, the workpiece is clamped by the clamping and rotating mechanism inside the machine tool. The controller 2 regulates the power, frequency, and heating time of the induction heating component. The induction coil generates eddy currents on the surface or in a localized area of ​​the workpiece through electromagnetic induction, causing the target area of ​​the workpiece to heat up rapidly. When the workpiece reaches the predetermined heating temperature, the cooling system and the quenching fluid circulation system are immediately activated. After the quenching fluid is filtered and cooled by the circulation system, it is rapidly sprayed onto the high-temperature area of ​​the workpiece through the nozzle. The strong cooling capacity of the quenching fluid instantly cools the surface of the workpiece. The working principle of the main body 1 of the combined induction hardening machine tool is existing technology, and this technical solution only provides a brief description.

[0046] When the machine tool is quenching, the heat radiation generated by heating and the evaporation of quenching liquid will cause the temperature of the door body 3 to rise. The heat is first transferred to the mounting plate 9 which is connected to the door body 3 by bolts. The through hole on the back of the mounting plate 9 ensures the stability of the connection with the door body 3.

[0047] As a key component connecting the mounting plate 9 and the handle 4, the bracket 5 has a double Y-shaped bending structure that extends the heat conduction path when heat is transferred from the mounting plate 9 to the handle 4, while increasing the contact area with the external airflow, making it easier for heat to dissipate through airflow. The hollow internal design reduces the heat conduction cross-sectional area and lowers the heat transfer rate. The 316 stainless steel material, due to its low to medium thermal conductivity among metals, further slows down heat transfer and can resist corrosion from sweat when workers come into contact with it, maintaining structural stability.

[0048] The filling layer 8 is phenolic foam, which fills the hollow area inside the bracket 5. Its heat-resistant and flame-retardant properties can reduce the convection of air inside the bracket 5 caused by thermal expansion and contraction, avoid air flow to enhance heat transfer, and thus enhance the overall heat insulation effect of the bracket 5.

[0049] The thermal break sleeve 6 is made of mica-reinforced phenolic resin composite material. Phenolic resin itself has high thermal resistance and good mechanical strength. After being reinforced with mica, the thermal resistance is further improved. Its T-shaped cross-section structure can physically isolate the bracket 5 and the handle 4, break the thermal bridge between them, and reduce the transfer of heat from the bracket 5 to the handle 4. The handle 4 is also made of 316 stainless steel, the same material as the bracket 5. It has both corrosion resistance and low thermal conductivity to reduce the accumulation of heat at the handle 4, thus reducing the temperature rise of the handle 4.

[0050] Overall, the components work together to reduce heat buildup in the handle and lower the risk of burns by extending the heat transfer path, reducing the heat conduction rate, isolating thermal bridges, and reducing air convection. At the same time, the design of a stable connection and easy replacement ensures the long-term effective operation of the equipment.
