Description

Technical Field

[0001] This invention relates to the field of heat treatment, specifically to a heat treatment equipment for the production of lightweight anti-tilt springs. Background Technology

[0002] In the field of automotive chassis technology, anti-roll springs (also known as stabilizer bars or anti-roll bars) are key components for improving vehicle cornering stability. They typically have a U-shaped structure with connecting holes at both ends for linkage with the suspension system. With the trend towards lightweighting, anti-roll bars made of aluminum alloy have become mainstream, but they must undergo precise heat treatment (such as annealing and aging) after forming to achieve the required mechanical properties.

[0003] However, existing heat treatment equipment exhibits significant technical limitations when dealing with the unique U-shaped geometry and end connection hole structure of anti-tilt rods. Traditional clamping and conveying methods struggle to achieve uniform heating and stable clamping of components during the heating process. In particular, due to the complex structure of the anti-tilt rod, uneven temperature distribution easily occurs between its curved and straight sections, in areas of wall thickness difference, and around the end connection holes during static or simple translational heating. This leads to inconsistent material microstructure and residual stress concentration after annealing, which severely affects the fatigue strength and service life of the product, and may even cause premature fracture. At the same time, existing equipment generally lacks the function of synchronously driving the anti-tilt rod to rotate around its own axis during automated conveying, making it impossible to achieve circumferential uniform heating. Furthermore, the clamping mechanism often cannot adapt to the connection hole positions and U-shaped contours of anti-tilt rods of different sizes, resulting in problems such as clamping interference, heating obstruction, or uneven clamping force, which further exacerbates the fluctuations in heat treatment quality.

[0004] Therefore, there is an urgent need to develop a dedicated heat treatment equipment that can take into account automated conveying, adaptive clamping, and synchronous rotary heating, in order to solve the core defect of uneven heating of U-shaped anti-roll bars during annealing, ensure their structural integrity and performance consistency, and meet the manufacturing requirements of high-quality lightweight chassis components. Summary of the Invention

[0005] The purpose of this invention is to provide a lightweight anti-tilt spring production heat treatment equipment in order to solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lightweight anti-tilt spring production heat treatment equipment, comprising an equipment body, with sprockets rotatably connected to both ends of the equipment body, the number of sprockets being two sets, the two sets of sprockets being connected by a fixed rod, a chain wound around the outer side of the sprockets, slots being equidistantly opened on the inner side of the two sets of chains, a connecting mechanism being provided between the two sets of slots, a transmission rod being installed on one side of the connecting mechanism, a rotating shaft being rotatably connected inside the transmission rod, a gear being fixed at the bottom of the rotating shaft, and the inner wall of the equipment body being connected by an installation... A rack that meshes with a gear is fixed to the mounting bracket. A first bevel gear is fixed to the top of the rotating shaft. A transmission shaft is rotatably connected to one side of the transmission rod. A second bevel gear that penetrates into the transmission rod is fixed to one side of the transmission shaft. The second bevel gear meshes with the first bevel gear. A clamping cylinder is provided on one side of the transmission shaft. A rectangular sliding column is fixed to one side of the clamping cylinder. A rectangular sliding groove that cooperates with the rectangular sliding column is opened on one side of the transmission shaft. A ceramic spring is installed at the bottom of the rectangular sliding groove. The end of the ceramic spring is connected to the rectangular sliding column.

[0007] As a further embodiment of the present invention: the connecting mechanism includes a connecting plate located between two sets of chains, with limiting grooves on both sides of the connecting plate, and a locking pin slidably connected inside the limiting grooves. A cavity is provided in the middle of the connecting plate, and a fourth bevel gear is rotatably connected to the inner walls on both sides of the cavity. A stud is fixed to one side of the fourth bevel gear, penetrating into the locking pin, and the stud is connected to the locking pin by threads. A rotary knob is rotatably connected to the front surface of the connecting plate, and a third bevel gear that meshes with the fourth bevel gear is fixed to one end of the rotary knob. The locking pin and the slot cooperate with each other.

[0008] As a further embodiment of the present invention: a heating chamber is installed at the middle position of the top of the device body, an electromagnetic heating coil is installed on the inner wall of the heating chamber, and the chain runs through the interior of the heating chamber.

[0009] As a further embodiment of the present invention: robotic arm mounting platforms are installed on both sides of the rear surface of the device body, and a stepper motor is installed on one side of the rear surface of the device body. The output end of the stepper motor is connected to a sprocket, and a disassembly mechanism is installed on both sides of the front surface of the device body.

[0010] As a further embodiment of the present invention: the disassembly mechanism includes a fixing plate fixed to the equipment body, an installation groove is provided at the middle position of the top of the fixing plate, a dual-axis electric push rod is installed inside the installation groove, positioning grooves are provided on both sides of the top of the fixing plate, positioning blocks are slidably connected inside the positioning grooves, and the output end of the dual-axis electric push rod is connected to the positioning block.

[0011] As a further embodiment of the present invention: the number of positioning blocks is two, and electromagnetic sliding grooves are formed inside the two positioning blocks. Electromagnetic sliding columns are slidably connected inside the electromagnetic sliding grooves, and a locking plate is fixed at the end of the electromagnetic sliding column.

[0012] As a further embodiment of the present invention: the number of clamping cylinders is two sets, the two sets of clamping cylinders are symmetrical to each other, and a limiting plate that cooperates with the clamping plate is fixed on the outside of the clamping cylinder.

[0013] As a further embodiment of the present invention: the cross-section of the slot and the locking pin is rectangular, and a hexagonal wrench groove is provided on one side of the rotary knob.

[0014] As a further embodiment of the present invention: a control console is installed on one side of the device body, the control console is electrically connected to a dual-axis electric push rod, and the control console is electrically connected to a stepper motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Achieve adaptive and precise clamping, enhancing clamping stability and adaptability. Through the adjustable-pitch connection mechanism and the cooperation of the clamping cylinders at both ends, it can precisely adapt to the connection hole positions and overall contour dimensions of U-shaped anti-tilt rods of different specifications, achieving stable and reliable adaptive clamping. This design effectively avoids the problems of heat shielding, localized stress concentration, and micro-deformation of components caused by improper clamping points or uneven force in traditional clamping methods, laying a physical foundation for uniform heat treatment.

[0016] 2. Ensuring uniformity in the heating process and significantly improving heat treatment quality. During the continuous passage of the anti-tilt bar through the heating chamber by the chain conveyor system, an innovative mechanism utilizes the meshing transmission of gears and a fixed rack to automatically drive the anti-tilt bar to rotate continuously and uniformly around its own axis. This mechanism allows the U-shaped bar and its complex end connection holes to receive uniform circumferential heat radiation, fundamentally solving the problem of uneven heating caused by irregular component geometry, differences in wall thickness, and varying heat capacities. This significantly improves the uniformity of the material structure and the rationality of residual stress distribution after annealing, greatly reducing the risk of early fatigue fracture due to localized overheating or underheating.

[0017] 3. Achieve fully automated operation, improving production efficiency and process consistency. By combining a programmable stepper motor with an automated disassembly mechanism, the entire process of the anti-tilt bar—from loading and clamping, conveying and heating to cooling and unloading—is fully automated. This not only significantly reduces manual intervention and improves production efficiency but also ensures the stability and repeatability of heat treatment process parameters for each batch of products, facilitating large-scale, high-quality, and consistent production.

[0018] 4. Enhanced equipment versatility and process flexibility. The modular connection mechanism and adjustable conveyor spacing design allow the same equipment to flexibly handle anti-tilt bar products of different lengths and specifications, improving equipment versatility and production line adaptability. Simultaneously, the control console allows for precise adjustment of conveyor speed, heating time, and rotation parameters, facilitating optimization of heat treatment process windows and adaptation to different material or process requirements.

[0019] In summary, this equipment, through its integrated adaptive clamping, continuous conveying, and synchronous rotary heating functions, provides a reliable and advanced technical solution for the high-quality, high-efficiency, and highly consistent heat treatment production of lightweight anti-tilt rods.

[0022] 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.

[0023] Please see Figures 1-9 In this embodiment of the invention, a heat treatment device for producing lightweight anti-tilt springs includes a device body 1. Two sets of sprockets 5 are rotatably connected to both ends inside the device body 1. These two sets of sprockets 5 are connected by a fixing rod. Chains 7 are wound around the outer sides of the sprockets 5. Slots are equidistantly spaced on the inner sides of the two sets of chains 7. A connecting mechanism 8 is provided between the two sets of slots. A transmission rod 10 is installed on one side of the connecting mechanism 8. A rotating shaft 11 is rotatably connected inside the transmission rod 10. A gear 12 is fixed to the bottom of the rotating shaft 11. A rack 9 that meshes with the gear 12 is fixed to the inner wall of the device body 1 via a mounting bracket. A first bevel gear 15 is fixed to the top of the rotating shaft 11. A transmission shaft 14 is rotatably connected to one side of the transmission rod 10. A second bevel gear 16, which penetrates into the transmission rod 10, is fixed to one side of the transmission shaft 14. The second bevel gear 16 meshes with the first bevel gear 15. A clamping cylinder 13 is provided on one side of the transmission shaft 14. A rectangular slide column 19 is fixed to one side of the clamping cylinder 13. A rectangular slide groove 18, which cooperates with the rectangular slide column 19, is opened on one side of the transmission shaft 14. A ceramic spring 20 is installed at the bottom of the rectangular slide groove 18. The end of the ceramic spring 20 is connected to the rectangular slide column 19.

[0024] In this embodiment: the sprocket 5 rotates, driving the chain 7 to rotate. The two sets of parallel chains 7 drive the transmission rod 10 to move through the connecting mechanism 8. When the transmission rod 10 moves, it drives the clamping cylinder 13 to move. The two sets of symmetrical clamping cylinders 13 clamp the lightweight anti-tilt spring (the clamping cylinder 13 can be inserted into the connecting holes at both ends of the lightweight anti-tilt spring for insertion and compression fixation), thereby driving it to move into the interior of the heating chamber 6. At this time, the gear 12 and the rack 9 cooperate with each other. When the connecting mechanism 8 moves, the gear 12 rotates. The gear 12 drives the first bevel gear 15 to rotate through the rotating shaft 11. The first bevel gear 15 drives the transmission shaft 14 to rotate through the second bevel gear 16. The transmission shaft 14 drives the clamping cylinder 13 to rotate. The two sets of symmetrical clamping cylinders 13 drive the lightweight anti-tilt spring to rotate, so that the lightweight anti-tilt spring is evenly heated inside the heating chamber 6, improving the annealing effect and avoiding breakage due to uneven heating.

[0025] Please refer to this carefully. Figure 1 , Figure 3 and Figure 7The connecting mechanism 8 includes a connecting plate 801 located between two sets of chains 7. Limiting grooves 808 are formed on both sides of the connecting plate 801. A locking post 807 is slidably connected inside the limiting groove 808. A cavity 804 is formed in the middle of the connecting plate 801. Fourth bevel gears 805 are rotatably connected to the inner walls of both sides of the cavity 804. A stud 806 is fixed to one side of each fourth bevel gear 805, penetrating into the locking post 807. The stud 806 is connected to the locking post 807 via threads. A rotary knob 802 is rotatably connected to the front surface of the connecting plate 801. A third bevel gear 803, meshing with the fourth bevel gear 805, is fixed to one end of the rotary knob 802. The locking post 807 and the limiting groove 808 cooperate with each other. The cross-sections of the limiting groove 808 and the locking post 807 are rectangular. A hexagonal wrench groove is formed on one side of the rotary knob 802.

[0026] In this embodiment: A hexagonal wrench is inserted into the hexagonal wrench slot to rotate the rotary knob 802. The rotary knob 802 rotates the third bevel gear 803, which in turn rotates two sets of fourth bevel gears 805 relative to each other. The two sets of fourth bevel gears 805 rotate two sets of studs 806 with identical threads. With the studs 806 and locking pins 807 cooperating with each other, and the locking pins 807 and limiting slots 808 mutually limiting each other, the screw moves, thereby driving the two sets of symmetrical locking pins 807 to move relative to each other. With the cooperation of the slots, it is easy to install the connecting mechanism 8 between the two sets of parallel chains 7. At the same time, the distance between the two sets of symmetrical connecting mechanisms 8 can be modified according to the length of the anti-tilt spring, thereby improving its practicality.

[0027] Please refer to this carefully. Figure 1 A heating chamber 6 is installed at the middle of the top of the device body 1. An electromagnetic heating coil is installed on the inner wall of the heating chamber 6. A chain 7 runs through the interior of the heating chamber 6. Robotic arm mounting platforms 4 are installed on both sides of the rear surface of the device body 1. A stepper motor 2 is installed on one side of the rear surface of the device body 1. The output end of the stepper motor 2 is connected to the sprocket 5. A control console is installed on one side of the device body 1. The control console is electrically connected to the stepper motor 2.

[0028] In this embodiment: the console controls the forward and reverse rotation time of the stepper motor 2, which can control the time the lightweight anti-tilt spring is inside the heating chamber 6. At the same time, the console controls the start of the robot on the robot mounting platform 4, thereby facilitating the installation and removal of the lightweight anti-tilt spring.

[0029] Please refer to this carefully. Figure 4 and Figure 8The front surface of the device body 1 is equipped with disassembly mechanisms 3 on both sides. The disassembly mechanism 3 includes a fixing plate fixed to the device body 1. A mounting groove 301 is opened at the middle position of the top of the fixing plate. A dual-axis electric push rod 302 is installed inside the mounting groove 301. The control console is electrically connected to the dual-axis electric push rod 302. Positioning grooves 303 are opened on both sides of the top of the fixing plate. Positioning blocks 304 are slidably connected inside the positioning grooves 303. The output end of the dual-axis electric push rod 302 is connected to the positioning blocks 304. There are two positioning blocks 304. Electromagnetic sliding grooves 305 are opened inside the two positioning blocks 304. Electromagnetic sliding columns 306 are slidably connected inside the electromagnetic sliding grooves 305. A clamping plate 307 is fixed at the end of the electromagnetic sliding column 306. There are two sets of clamping cylinders 13. The two sets of clamping cylinders 13 are symmetrical to each other, and a limiting plate 17 that cooperates with the clamping plate 307 is fixed on the outside of the clamping cylinders 13.

[0030] In this embodiment: the control console controls the start and stop of the electromagnetic heating coil in the heating chamber 6. At the same time, the control console controls the start of the dual-axis electric push rod 302, electromagnetic slide 305 and electromagnetic slide column 306, which in turn drives the clamping plate 307 to move. After the clamping plate 307 moves and cooperates with the limiting plate 17, it controls the two sets of clamping cylinders 13 to move in opposite directions.

[0031] The control console controls the electromagnetic slide rail 305 and the electromagnetic slide column 306, thereby changing the position of the electromagnetic slide column 306 and controlling the dual-axis electric push rod 302 to start. The dual-axis electric push rod 302 drives the clamping plate 307 to move relative to each other through the electromagnetic slide column 306. The clamping plate 307 presses the limiting plate 17 and drives it to move in the opposite direction, thereby driving the two sets of symmetrical clamping cylinders 13 to move in the opposite direction, so that the lightweight anti-tilt spring loses its compressive force, making it easier to install and remove using a robot.

[0032] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
