Abstract
Description
Technical Field
[0001] This invention relates to the field of pressure quenching machine technology, and particularly to a multi-directional constrained dual-heating power supply dual-coil linear guide induction heating pressure quenching machine. Background Technology
[0002] In the field of mechanical manufacturing, the quenching process of large-sized guide rails has always been a critical step in production. Traditional guide rail quenching processes typically employ induction heating with a single power source and a single coil.
[0003] However, this heating method has significant limitations. Because single-coil heating struggles to achieve uniform heating of different parts of the guide rail, a large temperature gradient occurs in different areas during quenching. This uneven temperature distribution not only makes the quenched guide rail prone to cracking but also easily leads to grinding cracks during subsequent grinding, severely impacting the guide rail's service life and machining accuracy. Therefore, improvements to the existing technology are necessary. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1:
[0035] Please see Figures 1-8 As shown, the present invention is a multi-directional constrained dual-heating-power-suction-pressing-quenching machine tool with dual coils and linear guide rails, comprising...
[0036] The machine frame 1 includes a loading mechanism 2, a pushing mechanism 3, a heating and quenching mechanism 4, a unloading mechanism 5, and a control system 6, all mounted on the machine frame 1. The loading mechanism 2, the pushing mechanism 3, the heating and quenching mechanism 4, and the unloading mechanism 5 are connected in series. The heating and quenching mechanism 4 includes a preheating station 41, two quenching stations 42 arranged opposite each other, and a tempering station 43. The tempering station 43 and the preheating station 41 are located on both sides of the quenching station 42. The preheating station 41, the two quenching stations 42 arranged opposite each other, and the tempering station 43 all include a load 411 mounted on the machine frame 1. One end of the load 411 is connected to two heating coils 412 via a bracket, and a quenching liquid nozzle 413 is mounted on the bracket.
[0037] Specifically, the quenching fluid nozzle 413 is used to spray out the quenching fluid, which is a PAG water-soluble quenching agent. The quenching fluid is stored in the machine tool base. The fine filter of the three-stage filter system is delivered to the quenching station 42 by a high-pressure pump, and the water valve controls the on and off.
[0038] As can be seen from the above, the heating and quenching mechanism 4 achieves multi-stage heating treatment of the guide rail workpiece by setting up a preheating station 41, a quenching station 42, and a tempering station 43. The quenching station 42 adopts a dual-power supply + dual-coil structure and uses dual-frequency continuous quenching. The guide rail workpiece is first heated to 600-750℃ in the preheating station 41, and then heated to 850-950℃ in the quenching station 42. Then, quenching liquid is sprayed out through the quenching liquid nozzle 413 for rapid cooling, which can reduce temperature deviation between different parts, reduce temperature gradient in the same part, improve hardness and consistency of structure, and improve quenching cracks and grinding cracks. The front and rear guide rail surfaces adopt independent heating and independent cooling, which improves the uniformity of heating and cooling processes and reduces the difficulty of coil manufacturing and process debugging. At the same time, due to the shortening of the effective heating circuit of the coil, the cooling is more sufficient, the coil life is improved, and ultimately the induction quenching deformation of the guide rail is reduced, and the production efficiency is improved.
[0039] The dual-coil design allows one coil to preheat the entire workpiece or a specific area, while the other coil is used for final heating to the quenching temperature. Alternatively, the two coils can each handle different parts of the workpiece, achieving more precise and uniform temperature control. The dual coils can work simultaneously to accelerate heating or operate independently to accommodate workpieces of different shapes or heating requirements, demonstrating a user-friendly design.
[0040] The control system 6 includes a machine tool control cabinet located on one side of the frame 1.
[0041] As shown above, control system 6 achieves automated control of the entire press quenching machine through the machine tool control cabinet. Based on the material, shape, structure, and technical requirements of the guide rail, control system 6 can determine the frequency and power of the power supply and design multiple sets of preheating coils and quenching coils according to the shape and electromagnetic effect of the guide rail. By coordinating with appropriate process parameters, optical microscopy is used to evaluate the consistency of the hardened layer structure at different locations on the working surface, and Vickers hardness tester is used to evaluate the consistency of the hardness and depth of the hardened layer at different locations on the working surface. In addition, control system 6 can also conduct full life cycle service accuracy retention and reliability tests for verification, and formulate guide rail dual-frequency quenching heat treatment process specifications, thereby achieving efficient and precise quenching process control.
[0042] The heating and quenching mechanism 4 also includes a preheating power supply 414, a first quenching power supply 415, a second quenching power supply 416, and a tempering power supply 417, which are disposed on one side of the control system 6.
[0043] As can be seen from the above, the preheating power supply 414 provides power to the heating coil 412 on the preheating station 41, the first quenching power supply 415 and the second quenching power supply 416 provide power to the heating coil 412 on the two quenching stations 42, adopting a dual power supply + dual coil structure, and the tempering power supply 417 provides power to the heating coil 412 on the tempering station 43.
[0044] The dual heating power supply design provides two independently adjustable high-frequency / medium-frequency power supplies to the two induction coils. Independent control allows for independent and precise adjustment of the power and frequency of each coil, enabling control of complex heating curves and temperature distributions. Furthermore, different coils can be designed for different power levels or frequency ranges, thereby improving system capacity and stability, and further enhancing overall heating capability and system reliability.
[0045] The frame 1 is provided with a cooling circulation system 7 for cooling the heating and quenching mechanism 4 components. The cooling circulation system 7 includes a refrigeration unit 71 and a pump station 72 connected to the refrigeration unit 71.
[0046] As shown above, the cooling circulation system 7 provides artificial softened water cooling for the components of the medium-frequency power supply and load system. The system is installed on the right side of the quenching machine tool, with the refrigeration unit 71 and pump station 72 located at the rear right side of the machine tool, responsible for providing and delivering the cold source. The cooling circulation system 7 also includes a stainless steel water tank, a low-pressure cooling pump, a pressurized cooling pump, and a filter, and is equipped with a device for monitoring cooling water temperature, pressure, and return water flow rate. This cooling circulation system effectively reduces the temperature of the components during operation, ensuring stable equipment operation and extending the equipment's service life.
[0047] The pushing mechanism 3 includes a plurality of pushing wheels 31 mounted on the frame 1, and a pushing ring belt 32 is sleeved on the outer wall of the plurality of pushing wheels 31.
[0048] As shown above, the pushing mechanism 3 achieves uniform and precise movement of the workpiece through the pushing wheel 31 and the pushing belt 32. The workpiece moves quickly and accurately between the preheating station 41, the quenching station 42, and the tempering station 43 via a linear guide drive system. This high-precision linear guide transmission mechanism not only provides a low-friction, high-rigidity motion path, ensuring the stability of the process, but also facilitates integration with automated equipment such as loading / unloading robots and conveying systems, enabling continuous production and further improving production efficiency and automation.
[0049] A gap adjustment assembly is provided below the heating coil 412. The gap adjustment assembly includes a first drive member 418 disposed below the load 411. The first drive member 418 is connected to a rack 419 via an output shaft. A gear 420 is movably disposed on the frame 1 below the heating coil 412, and the gear 420 meshes with the rack 419.
[0050] As can be seen from the above, the gap adjustment assembly, through the cooperation of the first driving component 418, the rack and pinion 419, and the gear 420, can adjust the gap between the heating coil 412 and the workpiece. This design can precisely adjust the distance between the heating coil 412 and the workpiece according to different shapes and sizes of workpieces, thereby achieving a more uniform heating effect. At the same time, this adjustment mechanism also ensures the adaptability and flexibility of the equipment, enabling it to meet the heating requirements of different workpieces.
[0051] The heating and quenching mechanism 4 also includes a multi-directional constraint component mounted on the frame 1. The multi-directional constraint component includes a plurality of constraint mold slots 421 fixedly mounted on the frame 1. A frame rod is fixedly mounted on the frame 1. A second driving member 422 is fixedly connected to one side of the frame rod. A clamping block 423 is fixedly connected to the second driving member 422 through an output shaft. The clamping block 423 cooperates with the constraint mold slots 421 to constrain and pressurize the guide rail workpiece.
[0052] As can be seen from the above, the multi-directional constraint assembly, through the cooperation of the constraint mold groove 421, the support rod, the second driving component 422, and the clamping block 423, can apply pressure to the workpiece from multiple directions during the press quenching process. This multi-directional constraint mechanism is the core feature of the press quenching die. Targeting the complex shape of the linear guide rail, it applies constraint forces from multiple directions during quenching and cooling shrinkage, actively counteracting or guiding shrinkage deformation, thereby ensuring that the final dimensional and shape accuracy is far superior to that of free quenching. In this way, quenching deformation can be effectively controlled, further improving the quality and performance of the product.
[0053] Example 2:
[0054] The working method of a multi-directional constrained dual-heating-power-double-coil linear guide induction heating and pressing machine tool includes the following steps:
[0055] S1. Loading: The guide rail components are automatically conveyed to the pushing mechanism 3 by the loading mechanism 2;
[0056] S2. Pushing material: The control system 6 controls the drive wheel 31 and the push belt 32 to rotate, further pushing the guide rail component into the preheating station 41.
[0057] S3. Induction heating: After medium-frequency heating at the preheating station 41, the workpiece enters the quenching station 42. The dual heating power supply uses high-frequency heating to drive the dual heating coils 412 respectively. According to the preset program, the workpiece is heated quickly and accurately. It can include preheating and final heating stages to reach the quenching temperature.
[0058] S4. Pressure quenching: The multi-directional constraint mold closes rapidly, and the guide rail workpiece is clamped from multiple directions by the cooperation of the clamping block 423 and the constraint mold groove 421. A preset pressure is applied. At the same time, the quenching medium is sprayed onto the surface of the guide rail workpiece through the quenching liquid nozzle 413 for rapid cooling and quenching. The phase transformation is completed under pressure constraint to obtain a high-hardness martensitic structure, and the deformation of the guide rail workpiece is strictly controlled.
[0059] S5. Transfer: The heated guide rail workpiece is moved at a constant speed and with precision to the medium-frequency induction tempering station 43 via a linear guide rail system.
[0060] S6. Unloading: The tempered workpiece is removed for further processing.
[0061] S7. Cycle: The entire process is highly automated, with heating and quenching of each workpiece performed cyclically.
[0062] As can be seen from the above, the working method of the multi-directional constraint dual-heating power supply dual-coil linear guide induction heating and pressing quenching machine described in this embodiment achieves efficient and precise heating and pressing quenching of the guide rail workpiece through a series of orderly and closely connected steps. In step S1, the guide rail workpiece is automatically fed by the feeding mechanism 2 and accurately transported to the pushing mechanism 3, laying the foundation for subsequent processing. In step S2, the control system 6 precisely controls the pushing wheel 31 and the pushing belt 32 to smoothly push the guide rail workpiece to the preheating station 41. At this time, the preheating station 41 uses the medium frequency power supply to drive the heating coil 412 to preheat the guide rail workpiece, so that its temperature rises uniformly to 600-750℃, preparing it for subsequent quenching. Next, in step S3, the guide rail component is pushed to the quenching station 42. Dual heating power supplies use high-frequency heating to drive dual heating coils 412, rapidly and precisely heating the guide rail component according to a preset program, covering both preheating and final heating stages, quickly raising its temperature to 850-950℃, reaching the high-temperature conditions required for quenching. Subsequently, in step S4, the multi-directional constraint mold quickly closes, and the clamping block 423 tightly engages with the constraint mold groove 421, applying preset pressure to the guide rail component from multiple directions. Simultaneously, the quenching medium is precisely sprayed onto the surface of the guide rail component through the quenching liquid nozzle 413, achieving rapid cooling and quenching. Under the combined action of multi-directional constraint pressure and the quenching medium, the guide rail component undergoes a phase transformation, forming a high-hardness martensitic structure, with the deformation strictly controlled within a very small range, ensuring the dimensional accuracy and shape stability of the workpiece. After quenching, in step S5, the heated guide rail workpiece is moved uniformly and precisely to the medium-frequency induction tempering station 43 using a linear guide system for tempering treatment, further optimizing the workpiece's performance. Finally, in step S6, the tempered workpiece is removed from the machine tool and enters subsequent processing steps. The entire workflow is highly automated and cyclical in step S7, greatly improving production efficiency, reducing manual intervention, and ensuring the consistency and stability of product quality. This working method fully demonstrates the machine tool's core advantages in improving heating efficiency, controlling quenching deformation, enhancing production automation, and ensuring product quality, providing strong technical support for the efficient and high-quality machining of large-sized guide rails.
