Description

Technical Field

[0001] This invention relates to the field of general-purpose metal heat treatment equipment, and in particular to an automated heat treatment device and method based on a pulley. Background Technology

[0002] As a core component of mechanical transmission systems, pulleys are widely used in automobile manufacturing, industrial equipment, agricultural machinery, and various transmission devices. Their performance directly determines the reliability, efficiency, and lifespan of the entire transmission system. Heat treatment processes, especially quenching processes, are key technologies for improving the surface hardness, wear resistance, and fatigue strength of pulleys. Through precise heat treatment, pulleys can maintain stable geometric accuracy and durable mechanical properties even under heavy loads and friction. Currently, the mainstream heat treatment methods for pulleys in the industry are overall quenching or local induction hardening, which aim to obtain martensitic structures to improve surface hardness.

[0003] In existing pulley heat treatment equipment, the complete heat treatment cycle of each pulley is strictly equal to the sum of its processing time and auxiliary time. Heating and quenching are necessary process times that are difficult to reduce significantly. During clamping and unloading, the expensive heating power supply, cooling system and machine tool body are completely idle and waiting, resulting in low overall equipment utilization. At the same time, the equipment requires manual operation by workers to align and clamp the pulleys, which increases the labor intensity of workers and reduces heat treatment efficiency. Summary of the Invention

[0014] A method of using an automated heat treatment device based on a pulley, comprising the following steps:

[0015] Step 1: The operator places the pulley blank into the inner clamping seat of the loading station. The system is started, and the electric telescopic rod pushes the inclined mechanism, so that the clamp automatically centers from the inside out and holds the workpiece. At the same time, the airbag inflates and expands to flexibly press one side of the clamp, completing the stable clamping.

[0016] Step 2: The servo motor drives the continuous conveyor platform to rotate intermittently, sending the clamped workpieces to the subsequent workstations in sequence. When workpiece A enters the heating and quenching station, workpiece B is being clamped or replaced at the loading station, thus achieving process overlap and continuous operation of the equipment.

[0017] Step 3: After the workpiece arrives at the heating and quenching station, the lifting mechanism automatically adjusts the height of the heat processor so that the heating plate is aligned with the part of the workpiece that needs to be hardened, and performs rapid and precise austenitizing heating. After heating is completed, the hollow water spray frame is aligned with the heating area with the help of the lifting mechanism. The flow controller precisely controls the quenching medium to perform uniform and all-round rapid spray cooling to obtain martensitic structure.

[0018] Step 4: The quenching liquid after spraying flows into the collection tank and is pumped back into the system for recycling by the circulation pump. The recycling module in the collection tank uses a reciprocating condenser rod to efficiently stir and cool the quenching liquid, keeping the liquid temperature stable. The workpiece that has completed heat treatment is rotated back to the loading station, the clamp is automatically released, the workpiece is removed and replaced, and it waits for the next work cycle.

[0019] As can be seen from the above, the automated heat treatment equipment based on pulleys provided by the present invention features a multi-station design for the heat treatment module, which realizes the spatial parallelism and temporal overlap of processes such as loading and unloading, heating, and quenching. This allows the core process unit to work continuously, eliminates idling, significantly improves equipment utilization, and enables fully automated operation. Only manual batch loading and unloading and monitoring are required, greatly reducing manual intervention and labor intensity. By adjusting the clamping range through the program, it can adapt to pulleys of different sizes without changing the fixtures, quickly responding to multi-variety, small-batch orders, and further improving productivity through extremely short changeover time.

[0038] Reference Figures 1-8 In a preferred embodiment, a fixture cover plate 9 is bolted to one side of the heat treatment fixture frame 6, and two round holes are opened on both the fixture cover plate 9 and one side of the heat treatment fixture frame 6. An adjusting screw 735 is connected to the interior of the two opposing round holes 2 through bearings.

A screw nut block 706 is fixedly connected to one side of each of the two lifting support plates 705. A control panel 5 is provided on one side of the heat treatment fixture frame 6.

[0039] Reference Figures 1-8 In a preferred embodiment, a tooling cover plate 2 is bolted to one side of the protective tooling frame 2, and a flow controller 709 is provided on one side of the tooling cover plate 2. Two metal telescopic pipes 714 are fixedly connected to the water outlet of the flow controller 709. The water outlet of the metal telescopic pipes 714 is fixedly connected to the inside of the hollow water spraying frame 717. A circulation pump 702 is provided on one side of the tooling cover plate 2. The water inlet of the circulation pump 702 is connected to the inside of the water collection tank 701 through a circulation water blower pipe 703. The water blower of the circulation pump 702 is connected to the water inlet of the flow controller 709 through a pipe.

[0040] Specifically, the operator places a batch of unfinished pulley blanks onto multiple inner clamping seats 731 at the loading station via the horizontal sliding door 3. At this time, the electric telescopic rod 723 corresponding to the station is in a retracted state, the control system is activated, the electric telescopic rod 723 at the current station extends, pushing the inclined lifting plate 724 upward. The inclined surface of the inclined lifting plate 724 presses against the roller 729, forcing the entire support frame 728 and the adjusting slider 725 fixed thereto to slide radially towards the center of the platform along the cross-shaped groove 720, compressing the telescopic spring 726. This process causes all the inner clamping seats 731 to spread outwards synchronously. Since the multiple inner clamping seats 731 are symmetrically distributed in a ring, they evenly clamp from the inner circle. The inner hole or hub of the pulley achieves automatic centering without manual alignment. Simultaneously, as the inclined lifting plate 724 rises, the sealed sliding plate 727, fixed to it, is pressed upwards within the air cylinder 730, forcing air into the airbag 734 through the air inflator 732. The airbag 734 inflates and expands, flexibly and forcefully pressing against the inner clamping seat 731 from one side, ensuring it remains stable and does not wobble during rotation and heat treatment. After clamping, the servo motor 719 starts, driving the entire continuous conveyor platform 712 to perform intermittent rotational motion via the rotating support rod 718. This rotational motion is precisely programmed and controlled by the control panel 5. When the first pulley completes clamping and rotates into the heating and quenching station, the treated and untreated pulleys can then be processed. The loading and unloading, heating power supply, heat processor 708, and hollow water-spraying circular frame 717 in the quenching system, among other core process units, remain operational throughout continuous production. This ensures complete overlap of processing times for different workpieces, eliminating idle waiting periods common in traditional equipment. When the pulley rotates directly below the heating and quenching station, the lead screw motor 711 drives two adjusting lead screws 735 to rotate synchronously via the belt 710. The lead screw nut block 706, which works in conjunction with the lead screws, drives the lifting support plate 705 to move vertically along the limit track 704. This precisely adjusts the height of the heat processor 708 and the hollow water-spraying circular frame 717 relative to the workpiece to accommodate pulleys of different diameters. Once the height is adjusted, the heating circular plate 716, which is essentially an induction heating coil, is energized, energizing the workpiece stationary within it. The lower pulley undergoes rapid, localized austenitizing heating on hardened areas such as the pulley groove. The heating power and time are preset by the control system according to the workpiece model. After heating, the lifting mechanism can be finely adjusted to align the hollow water spray frame 717 with the heating area. The flow controller 709 receives the command and precisely controls the flow rate and pressure of the quenching medium. The quenching medium is evenly and omnidirectionally sprayed onto the surface of the high-temperature workpiece through multiple nozzles of the hollow water spray frame 717 via the metal telescopic tube 714, achieving rapid and uniform cooling and obtaining a martensitic structure. The sprayed quenching liquid falls into the lower water collection tank 701. The circulation pump 702 pumps the liquid in the water collection tank 701 into the flow controller 709 through the circulation water pipe 703, forming a closed loop.After quenching and initial cooling, the pulley rotates back to the loading station with the platform. The electric telescopic rod 723 at this station retracts, and the inclined lifting plate 724 descends. Under the reset action of the telescopic spring 726, the adjusting slider 725 slides radially inward, and the inner clamping seat 731 is released. At the same time, the airbag 734 deflates and contracts, completely releasing the constraint on the inner clamping seat 731, realizing the replacement of the workpiece and starting the next cycle.

[0041] In specific application scenarios, the multi-station design of the continuous heat treatment module 7 allows for parallel spatial connection and temporal overlap of processes such as loading / unloading, heating, and quenching. The heating and quenching units never stop working, completely eliminating the persistent problem of "idling" in the core process system during loading and unloading of traditional equipment. This improves the overall utilization rate of the equipment. From automatic centering and clamping, programmed rotation, adaptive lifting to heating and quenching, the entire process requires no manual intervention. Operators only need to load / unload in batches and monitor the process, achieving full automation and significantly reducing reliance on manual labor and labor intensity. For pulleys with different inner and outer diameters, the system does not require the replacement of any clamping components. It only needs to call different programs to control the stroke of the electric telescopic rod 723 to automatically adjust the clamping range, enabling the equipment to quickly respond to the order requirements of "multiple varieties and small batches" with extremely short changeover time, thereby improving equipment productivity.

[0042] Reference Figure 1 , Figure 3 , Figure 5 , Figure 9 and Figure 10 In a preferred embodiment, a recycling module 8 is provided inside the water collection tank 701, and the recycling module 8 includes a drive motor 807. Guide grooves are provided on both sides of the water collection tank 701, and the same horizontal moving frame 803 is slidably connected inside the two guide grooves. A condenser 804 is provided on the horizontal moving frame 803, and multiple condensing rods 805 are provided at equal intervals on the condensing end of the condenser 804. An installation port 801 is provided on one side of the supporting fixture cabinet 1, and a fixture cover plate 311 is bolted to one side of the installation port 801.

[0043] Reference Figure 9 and Figure 10In a preferred embodiment, a circular hole three is provided on one side of the mounting port 801, and an anti-wear limiting cylinder 802 is fixedly connected inside the circular hole three. A push-pull cylinder 806 is slidably connected inside the anti-wear limiting cylinder 802. One end of the push-pull cylinder 806 is fixedly connected to one side of the horizontal moving frame 803. Two circular holes four are provided at the other end of the push-pull cylinder 806. The two circular holes four are connected to the same rotating shaft 808 through bearings. A drive motor 807 is fixedly connected to one side of the mounting port 801. A rotating circular plate 809 is fixedly connected to the drive end of the drive motor 807. A circular hole five is provided on the rotating circular plate 809 away from its center. An eccentric shaft 810 is connected inside the circular hole five through bearings. The eccentric shaft 810 and the rotating shaft 808 are movably connected to the same push-pull support rod 811.

[0044] Specifically, during the quenching process, the high-temperature workpiece transfers a large amount of heat to the quenching liquid, causing the liquid temperature in the water collection tank 701 to rise. Excessively high liquid temperature will seriously affect the quenching cooling rate, resulting in insufficient hardness of the workpiece. At this time, the drive motor 807 drives the rotating circular plate 809 to rotate. Through the eccentric shaft 810 and the push-pull support rod 811, the rotational motion is converted into the horizontal reciprocating linear motion of the push-pull cylinder 806 in the anti-wear limiting cylinder 802. The push-pull cylinder 806 drives the horizontal moving frame 803 and the condenser 804 and multiple condensing rods 805 installed on it to move back and forth in the quenching liquid in the water collection tank 701. The condensing rods 805 circulate refrigerant inside, which can efficiently absorb the heat of the liquid. Their horizontal reciprocating motion acts as a forced stirrer, breaking the water temperature stratification and allowing the hot water to fully contact the condensing rods 805, greatly improving the heat exchange efficiency and ensuring that the temperature of the quenching liquid is quickly and uniformly controlled within the process requirements.

[0045] In specific application scenarios, the integrated high-efficiency recycling module 8 is not just a cooler. Its reciprocating motion and stirring effect prevent local overheating and temperature stratification of the quenching liquid, providing a constant and ideal cooling environment for each quenching. This is the cornerstone for obtaining stable heat treatment quality and at the same time, it forms a resource reuse mechanism.

[0046] A method of using an automated heat treatment device based on a pulley, comprising the following steps:

[0047] Step 1: The operator places the pulley blank into the inner clamping seat 731 of the loading station. The system is started, and the electric telescopic rod 723 pushes the inclined plane mechanism, so that the clamp automatically centers from the inside to the outside and clamps the workpiece. At the same time, the air bag 734 inflates and expands, flexibly pressing one side of the clamp to complete the stable clamping.

[0048] Step 2: Servo motor 719 drives continuous conveyor platform 712 to rotate intermittently, sending the clamped workpieces to the subsequent workstations in sequence. When workpiece A enters the heating and quenching position, workpiece B is being clamped or replaced at the loading position, realizing process overlap and continuous operation of the equipment.

[0049] Step 3: After the workpiece arrives at the heating and quenching station, the lifting mechanism automatically adjusts the height of the heat processor 708 so that the heating circular plate 716 is aligned with the part of the workpiece that needs to be hardened, and performs rapid and precise austenitizing heating. After heating is completed, the hollow water spraying circular frame 717 is aligned with the heating area with the assistance of the lifting mechanism, and the flow controller 709 precisely controls the quenching medium to perform uniform and all-round rapid spray cooling to obtain martensitic structure.

[0050] Step 4: The quenching liquid after spraying flows into the water collection tank 701 and is pumped back into the system by the circulation pump 702 for recycling. The recycling module 8 in the water collection tank 701 uses the reciprocating condensing rod 805 to efficiently stir and cool the quenching liquid, keeping the liquid temperature stable. The workpiece that has completed the heat treatment is rotated back to the loading station, the clamp is automatically released, the workpiece is removed and replaced, and it waits for the next work cycle.

8. A method of using an automated heat treatment device based on a pulley, comprising using an automated heat treatment device based on a pulley as described in claim 7, characterized in that, Includes the following steps: Step 1: The operator places the pulley blank into the inner clamping seat (731) of the loading station. The system is started, and the electric telescopic rod (723) pushes the inclined plane mechanism, so that the clamp automatically centers from the inside to the outside and holds the workpiece. At the same time, the air bag (734) inflates and expands, flexibly pressing one side of the clamp to complete the stable clamping. Step 2: The servo motor (719) drives the continuous conveyor platform (712) to rotate intermittently, and sends the clamped workpieces to the subsequent workstations in sequence. When workpiece A enters the heating and quenching position, workpiece B is being clamped or replaced at the loading position, so as to achieve process overlap and continuous operation of the equipment. Step 3: After the workpiece arrives at the heating and quenching station, the lifting mechanism automatically adjusts the height of the heat processor (708) so that the heating plate (716) is aligned with the part of the workpiece that needs to be hardened, and performs rapid and precise austenitizing heating. After the heating is completed, the hollow water spray frame (717) is aligned with the heating area with the assistance of the lifting mechanism. The flow controller (709) precisely controls the quenching medium to perform uniform and all-round rapid spray cooling to obtain martensitic structure. Step 4: The quenching liquid after spraying flows into the water collection tank (701) and is pumped back to the system for recycling by the circulation pump (702). The recycling module (8) in the water collection tank (701) uses the reciprocating condenser rod (805) to efficiently stir and cool the quenching liquid, keeping the liquid temperature stable. The workpiece that has completed the heat treatment is rotated back to the loading station, the clamp is automatically released, the workpiece is removed and replaced, and it waits for the next work cycle.
