Description

Technical Field

[0001] This invention relates to the field of machining equipment, and more specifically to an automated quenching mechanism for continuous double quenching of long rods. Background Technology

[0002] The pins used in modern tower cranes require high hardness and wear resistance. Before processing the pins, the purchased raw material long rods need to be quenched. The current quenching of long rods mainly involves passing the long rods through multiple heating coils in sequence, heating the long rods through the heating coils, and then cooling them through the spray components at the ends of the multiple heating coils. However, this method requires the long rods to have high hardness and wear resistance. It is better to use water immersion quenching after heating the long rods. The continuous quenching mechanism for long rods mentioned above cannot achieve water immersion quenching of long rods. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes an automated quenching mechanism for continuous double quenching of long rods. After heating, the long rods are continuously quenched by immersion in water, thus ensuring high hardness and wear resistance.

[0004] To achieve the above objectives, the present invention provides an automated quenching mechanism for continuous double quenching of long rods, comprising a heating mechanism, an immersion cooling mechanism, and a cooling water circulation system. Both the heating mechanism and the immersion cooling mechanism are in two sets, alternating between each other. A conveying mechanism is provided between the heating mechanism and the immersion cooling mechanism, passing through them. The long rod is conveyed through the heating mechanism and the immersion cooling mechanism sequentially. A cooling water circulation system is installed on each set of immersion cooling mechanisms.

[0005] The immersion cooling mechanism includes multiple cooling water tanks, a translation component, a support component, and a lifting component. Multiple cooling water tanks are arranged side-by-side on the ground. A translation component is positioned between the bottom of each cooling water tank and the ground, enabling the cooling water tanks to reciprocate. This ensures that the multiple cooling water tanks and the heating mechanism are aligned in a straight line. A support component is positioned above each cooling water tank, connecting to the heating mechanism and corresponding vertically to the cooling water tank. A displacement component is positioned above the support component, enabling synchronous movement between the support component and the cooling water tank. A lifting component is positioned above each set of support components.

[0006] Preferably, the lifting assembly includes a mounting frame, rollers, and a lifting frame. Multiple sets of mounting frames are installed below the lifting frame, and rollers are installed on each set of mounting frames. A translation frame is provided on the top of the lifting frame, and a lifting assembly is provided between the translation frame and the lifting frame. When the mounting frame descends, the outer wall of the mounting frame abuts against the inner wall of the cooling water tank. The displacement assembly includes a gantry frame and a sliding seat. A gantry frame is erected above the translation frame, and the sliding seat is installed on the translation frame. The top of the sliding seat is engaged with the gantry frame for movement.

[0007] Preferably, the cooling water tank is a rectangular tank, with the top of one end and the bottom of the other end connected to the cooling water circulation system; the translation assembly includes a translation track, a translation block, and a translation drive assembly. The translation track is installed on the ground, and the translation block is installed on the translation track. The translation block is installed at the bottom of the cooling water tank, and the translation drive assembly is located between the cooling water tank and the ground; the translation drive assembly includes a translation lead screw and a stepper motor. The translation lead screw is installed on the output shaft of the stepper motor, and a threaded sleeve is fitted onto the translation lead screw. The grooved sleeve is installed at the bottom of the cooling water tank. Limit switches are installed on both sides of the multi-stage cooling water tank. When the side of the cooling water tank contacts the limit switch, the movement stops, and the next movement will reverse. A vertical elongated hole is opened on the side of each cooling water tank. A sliding plate is installed inside the elongated hole. The sliding plate is longer than the elongated hole. A lifting block is installed inside the elongated hole. A trigger block is installed on the outer wall of the lifting block. A proximity switch is installed below the trigger block. The proximity switch is connected to the stepper motor, and the stepper motor is started through the proximity switch.

[0008] Preferably, the conveying mechanism consists of multiple sets of pulleys arranged side by side, each pulley being driven to rotate by a motor. Each pulley has an annular V-shaped groove. Multiple pulleys located in the same heating mechanism are mounted on a linkage rod. A height adjustment component is provided between the linkage rod and the heating mechanism. Multiple distance sensors arranged in a circular array are provided on the outer periphery of the heating mechanism. The multiple distance sensors face the central axis of the heating mechanism and are equidistant from the central axis of the heating mechanism. The distance sensors are connected to the height adjustment component.

[0009] Preferably, a feeding mechanism is connected to the front end of the first heating mechanism. The feeding mechanism includes an inclined placement platform and a lifting baffle. The top surface of the placement platform is inclined. The conveying mechanism extends forward to one side of the placement platform. Long rods on the placement platform are rolled onto the conveying mechanism via the inclined surface for conveying. Two sets of lifting baffles that can be raised and lowered are installed at the bottom of the placement platform. The lifting baffles allow one rod to be fed onto the conveying mechanism at a time. The rear end of the last immersion cooling mechanism is connected to an unloading mechanism. The conveying mechanism extends backward. The unloading mechanism is installed at the end of the conveying mechanism. A receiving platform is provided on one side of the end of the conveying mechanism. The receiving platform is also inclined.

[0010] Preferably, the unloading mechanism includes a swing unloading arm and an unloading baffle. Multiple sets of unloading arms are arranged between the pulleys of the conveying mechanism and are rotatably connected to the conveying mechanism. An unloading baffle is provided at the end of the conveying mechanism. A long rod abuts against the unloading baffle. The unloading baffle slides against the end of the conveying mechanism. A spring is provided between the unloading baffle and the end of the conveying mechanism. A rack that moves with the unloading baffle is installed at the bottom of the unloading baffle. A gear that meshes with the rack is installed on each unloading arm. In this way, the unloading arm slowly rises and lifts the long rod upward to separate it from the pulley.

[0011] Preferably, a discharge plate is fixed at the end of the discharge arm away from the gear. The discharge plate is raised by rotating the discharge arm. The top surface of the discharge plate is inclined and the discharge plate is tilted towards the receiving platform.

Detailed Implementation

[0023] The invention will now be further described with reference to the accompanying drawings.

[0024] like Figure 1-9 An automated quenching mechanism for continuous double quenching of long rods includes a heating mechanism 1, an immersion cooling mechanism 2, and a cooling water circulation system 33. Both the heating mechanism 1 and the immersion cooling mechanism 2 are in pairs and are distributed alternately. The heating mechanism 1 consists of multiple sets of magnetic induction coils arranged side-by-side. When the long rod passes through the magnetic induction coils, the coils heat the rod. A conveying mechanism 27 is provided between the heating mechanism 1 and the immersion cooling mechanism 2, allowing the long rod to pass sequentially through the heating mechanism 1 and the immersion cooling mechanism 23. The cooling mechanism 2 is equipped with a cooling water circulation system 33 in each immersion cooling mechanism 2. When the long rod is quenched, it is heated by a magnetic induction coil. The temperature of the long rod is relatively stable when heated to 800-900℃. Then, the conveying mechanism 27 transports the long rod to the immersion cooling mechanism 2 for quenching and cooling. After quenching, the long rod is transported to the magnetic induction coil for secondary heating by the conveying mechanism 27. After secondary heating, the long rod is transported to the immersion cooling mechanism 2 for secondary quenching. This secondary quenching ensures the wear resistance of the long rod.

[0025] The immersion cooling mechanism 2 includes multiple cooling water tanks 3, a translation component 10, a lifting component 17, and a lifting component 25. Two rows of cooling water tanks 3 are arranged side-by-side on the ground. The translation component 10 is positioned between the bottom of each cooling water tank 3 and the ground, enabling the cooling water tanks 3 to move left and right back and forth. Thus, the multiple cooling water tanks 3 are aligned sequentially with the heating mechanism 1 via the translation component 10. A lifting component 17 is positioned above each cooling water tank 3, and the lifting component 17 is aligned with the heating mechanism 1. Mechanism 1 is connected, with the lifting assembly 17 corresponding vertically to the cooling water tank 3. A displacement assembly 22 is installed above the lifting assembly 17, enabling synchronous movement between the lifting assembly 17 and the cooling water tank 3. A lifting assembly 25 is installed above each set of lifting assemblies 17. During operation, a long rod passing through multiple magnetic induction coils is conveyed to the lifting assembly 17 via a conveying mechanism 27 for lifting. When the long rod leaves the magnetic induction coils and is completely placed on the lifting assembly 17, the lifting assembly 17... The long rod descends into the cooling water tank 3 for immersion cooling. The water in the cooling water tank 3 quenches the long rod. As the cooling water tank 3 moves to the left, the conveying mechanism 27 connects with the next set of lifting assemblies 17. The long rod, passing through the magnetic induction coil, is then conveyed onto the lifting assembly 17. When the heated long rod is conveyed onto the lifting assembly 17, the long rod in the left-side cooling water tank 3 is quenched. When the long rod on the right-side lifting assembly 17 extends into the cooling water tank 3, the long rod in the left-side cooling water tank 3 is quenched. The left-side lifting assembly 17 rises, the long rod separates from the cooling water tank 3, and the cooling water tank 3 moves to the right. Thus, the left-side lifting assembly 17 connects with the conveying mechanism 27. The heated long rod of the conveying mechanism 27 is conveyed to the lifting assembly 17. The long rod at the front end of the lifting assembly 17 pushes the long rod on the lifting assembly 17 backward. Thus, the long rod on the lifting assembly 17 is pushed to the rear conveying mechanism 27 for secondary heating. The long rod at the front end of the lifting assembly 17 replaces the long rod that has been quenched.

[0026] The lifting assembly 17 includes mounting frames 18, rollers 19, and a lifting frame 20. Two sets of mounting frames 18 are installed below the lifting frame 20. Each set of mounting frames 18 consists of two frames arranged side-by-side. Each mounting frame 18 is a portal frame. Multiple mounting frames 18 are fixed together by crossbars, meaning the ends of the crossbars are welded to the mounting frames 18. Rollers 19 are installed below each set of mounting frames 18 to support long rods. A translation frame 21 is bolted to the top. A lifting assembly 25, which is a lifting hydraulic cylinder, is installed between the translation frame 21 and the lifting frame 20. The cylinder body of the lifting hydraulic cylinder is bolted to the translation frame 21, and the top of the piston rod of the lifting hydraulic cylinder is bolted to the mounting frame 18. The lifting hydraulic cylinder is used to raise and lower the mounting frame 18, thus immersing the long rod on the lifting assembly 17 into the cooling water tank 3 for quenching. When the mounting frame 18 descends... The outer wall of the mounting bracket 18 abuts against the inner wall of the cooling water tank 3; the displacement assembly 22 includes a gantry frame 23 and a sliding seat 24. The gantry frame 23 is mounted above the translation frame 21, and the bottom of the gantry frame 23 is fixed to the ground by bolts. The sliding seat 24 is mounted on the translation frame 21. A convex slide rail is installed on the bottom of the gantry frame 23 by bolts. A convex groove is opened on the top of the sliding seat 24. The top of the sliding seat 24 is engaged with the convex slide rail and moves. The bottom of the sliding seat 24 is connected to the convex slide rail. A translation frame 21 is installed by bolts. Tie rods are installed at both ends of the translation frame 21 and the outer wall of the sliding seat 24 by bolts. When the long rod on the lifting assembly 17 needs to be quenched during operation, the lifting assembly 25 lowers the lifting assembly 17, and the mounting frame 18 of the lifting assembly 17 moves downward and abuts against the inner wall of the cooling water tank through the outer wall of the mounting frame 18. When the cooling water tank 3 moves horizontally from side to side, the lifting assembly 17 moves horizontally synchronously through the mounting frame 18.

[0027] The cooling water tank 3 is a rectangular tank 4. The top of one end of the cooling water tank 3 and the bottom of the other end are connected to the cooling water circulation system 33, which is the condenser. The inlet and outlet pipes of the condenser are connected to the front and rear ends of the cooling water tank 3, respectively. In this way, the water in the cooling water tank 3 is cooled and then fed back into the cooling water tank 3, thus realizing the circulation of cooling water. The translation component 10 includes a translation track 11, a translation block 12, and a translation drive component 13. The translation track 11 is horizontally installed on the ground by bolts. The translation block 12, which moves on the translation track 11, is mounted on the translation track 11. The translation block 12 is bolted to the bottom of the cooling water tank 3. The translation block 12 drives the cooling water tank 3 to move horizontally, thus facilitating the cooling water circulation. A translation drive assembly 13 is installed between the water tank 3 and the ground. The translation drive assembly 13 enables the translation block 12 to move left and right reciprocally. The translation drive assembly 13 includes a translation screw 14 and a stepper motor 15. The translation screw 14 is welded to the output shaft of the stepper motor 15. A threaded sleeve is fitted on the translation screw 14 (the translation screw 14 and the threaded sleeve are threadedly engaged), and the threaded sleeve is installed at the bottom of the cooling water tank 3 by bolts. The movement of the threaded sleeve drives the cooling water tank 3 to move left and right. Limit switches 16 (model WLNJ-TH-N limit switches 16) facing the side wall of the cooling water tank 3 are fixed to the ground on both sides of the cooling water tank 3 by bolts. When the two cooling water tanks move to the right, the cooling water tank 3 on the right side contacts the limit switch 16 on the right side. This triggers the limit switch 16, stopping the stepper motor 15 that drives the translation screw 14. The cooling water tank 3 stops moving, and the next movement will be in the opposite direction (i.e., the cooling water tank 3 moves to the left). Each cooling water tank 3 has a vertical elongated hole 5 on its side. A sliding plate 6 is installed inside the elongated hole 5, fitting against the inner wall of the cooling water tank 3. When the sliding plate 6 slides up and down, the elongated hole 5 is always covered by the sliding plate 6, preventing leakage. The sliding plate 6 is longer than the elongated hole 5. A lifting block 7, which slides up and down within the elongated hole 5, is engaged inside the elongated hole 5. A tension spring is welded between the lifting block 7 and the top of the elongated hole 5. A trigger block 8 is welded to the outer wall of the lifting block 7, protruding from the outer wall of the cooling water tank 3. A proximity switch 9 is installed below the trigger block 8, and is bolted to the outer wall of the cooling water tank. The proximity switch 9 is located at the bottom of the elongated hole 5. When the lifting block 7 descends to the bottom of the elongated hole 5, the trigger block 8 presses against the proximity switch 9, thus triggering the proximity switch 9. The limit switch 16 and the proximity switch 9 are connected to the input terminal of the controller (PLC) via wires. The lifting assembly 25 and the stepper motor 15 (the encoder of the stepper motor 15 is connected to the controller) are connected to the input terminal of the controller. During operation...The lifting assembly 17 on the right side is connected to the conveying mechanism 27. When the long rod is conveyed onto the lifting assembly 17, the lifting assembly 25 lowers the lifting assembly 17, causing the mounting bracket 18 of the lifting assembly 17 to descend and extend into the cooling water tank. As the mounting bracket 18 descends, it presses the sliding plate 6 downwards, causing the trigger block 8 to move downwards and trigger, thus starting the stepper motor 15. This causes the cooling water tank 3 to move to the right via the translation screw 14. When the cooling water tank 3 moves to the right and triggers the limit switch 16 on the right side, the stepper motor 15 stops working. When the lifting assembly 17 descends and extends into the left cooling water tank 3, the proximity switch 9 on the left cooling water tank 3 is triggered, causing the stepper motor 15 to start and rotate in the opposite direction, thus moving the cooling water tank 3 to the left. When the cooling water tank 3 moves to the left and contacts the limit switch 16 on the left, the limit switch 16 is triggered, and the stepper motor 15 stops working. This achieves the left and right movement of the cooling water tank 3.

[0028] The conveying mechanism 27 consists of multiple sets of pulleys 28 arranged side-by-side, each pulley 28 driven to rotate by a motor (the pulley 28 is fixed to the output shaft of the motor by welding, thus realizing the roller of the pulley 28). Each pulley 28 has an annular V-groove 29 to facilitate the center positioning of long rods. Multiple pulleys 28 located in the same group of heating mechanisms 1 are mounted on linkage rods 30 (two linkage rods 30 are set on the left and right sides of the same group of heating mechanisms 1, and multiple pulleys 28 are mounted on the two linkage rods 30 by bearings). Multiple vertical guide rods are installed on the table by bolts, and the vertical guide rods pass through the linkage rods. A linkage rod 30 is used to raise and lower along a vertical guide rod. A height adjustment assembly 31 is provided between the linkage rod 30 and the heating mechanism 1. Multiple heating mechanisms 1 are mounted on the table by bolts. The height adjustment assembly 31 includes a lifting screw, a servo motor, and a lifting sleeve. Two synchronous servo motors are mounted on the table. The output of the servo motors is connected to the output of the controller via wires. The controller controls the number of rotations of the servo motors. A gear 42 is mounted on the output shaft of the servo motor. Multiple vertically arranged lifting screws are mounted on the table via bearings. A lifting sleeve is fitted onto each lifting screw. The sleeve is threadedly engaged with the lifting screw, thus the lifting of the sleeve is achieved by the rotation of the lifting screw. The lifting sleeve is installed on the linkage rod 30 by bolts. The bottom of the lifting screw is fixed to the output shaft of the servo motor by welding to a sprocket. The sprockets below the same linkage rod 30 are driven by chain meshing, thus realizing the synchronous lifting of multiple linkage rods 30. Three ranging sensors 32 (VDM28-15-L1-IO / 73c / 110 / 122 laser ranging sensors 32) are installed in a ring array on the outer periphery of the heating mechanism 1 by bolts. One ranging sensor 32 is located on the heating machine. Above the heating mechanism 1, two more are located on either side of the heating mechanism 1. Multiple distance sensors 32 face the central axis of the heating mechanism 1 and are equidistant from the central axis. The distance sensors 32 are connected to the input of the controller, and the output of the controller is connected to the servo motor. The distance between the long rod and the heating mechanism 1 is measured by the multiple distance sensors 32. When the long rod is not coaxial with the heating mechanism 1, there is a difference in the distance measured by the top distance sensor 32 and the distance sensors 32 on both sides. The height of the pulley 28 is adjusted by the servo motor to make the measurement distance of the three distance sensors 32 consistent.

[0029] A feeding mechanism 34 is connected to the front end of the first heating mechanism 1. The feeding mechanism 34 includes an inclined placement platform 35 and lifting baffles 36. The top surface of the placement platform 35 is inclined. The conveying mechanism 27 extends forward to the left side of the placement platform 35. Long rods on the placement platform 35 are conveyed by rolling them onto the conveying mechanism 27 via the inclined surface. Two sets of lifting baffles 36 are installed at the bottom of the placement platform 35. The two sets of lifting baffles 36 are arranged opposite each other. One set of lifting baffles 36 is installed on the leftmost end face of the placement platform 35, and the other set of lifting baffles 36 is installed on the leftmost end face of the placement platform 35. The lowering baffle 36 passes through the placement platform 35. The distance between the two sets of lifting baffles 36 is the diameter of the long rod. The staggered lifting of the lifting baffles 36 enables one rod to be fed onto the conveying mechanism 27 each time. The rear end of the last immersion cooling mechanism 2 is connected to the unloading mechanism 37. The conveying mechanism 27 extends backward, and the unloading mechanism 37 is installed at the end of the conveying mechanism 27. A receiving platform 38 is set on the right side of the ground at the end of the conveying mechanism 27. The receiving platform 38 is also inclined. The quenched long rod is received through the receiving platform 38.

[0030] The unloading mechanism 37 includes a swing unloading arm 39 and an unloading baffle 40. Multiple sets of unloading arms are arranged between the pulleys 28 of the conveying mechanism 27. These arms are rotatably connected to the conveying mechanism 27, with one end of each unloading arm fixed to a rotating shaft by welding. Both ends of the rotating shaft are mounted on a linkage rod 30 via bearings. An unloading baffle 40 is located at the end of the conveying mechanism 27, with a long rod abutting against it. The unloading baffle 40 slides against the end of the conveying mechanism 27 (i.e., a sliding sleeve is fitted at the end of the linkage rod 30 of the conveying mechanism 27, and the unloading baffle 40 is fixed to the two sliding sleeves by bolts). A spring is welded between the unloading baffle 40 and the end of the conveying mechanism 27, pushing the unloading baffle 40 forward. At the bottom of the unloading baffle 40... A rack 41, fastened with bolts, moves along with the unloading baffle 40. A gear 42, welded to the rack 41, is installed on each unloading arm. The gear 42 is coaxial with the rotating shaft. As the unloading arm slowly rises, it lifts the long rod upwards and separates it from the pulley 28. When the long rod abuts against the unloading baffle 40 and continues to move backwards, the unloading baffle 40 slides backwards, moving backwards via the rack 41. This causes the unloading arm to slowly swing upwards and lower the long rod downwards. When the long rod separates from the pulley 28, the preceding long rod abuts against it. The long rod with the unloading baffle 40 continues to move backwards, while the unloading arm swings upwards. When the two long rods are misaligned, the long rod in contact with the unloading baffle 40 stops being conveyed backwards, and the long rod on the unloading arm rolls onto the receiving platform 38.

[0031] The unloading arm is fixed to the end away from the gear 42 by welding the unloading plate 43. The unloading plate 43 is raised by rotating the unloading arm. The top surface of the unloading plate 43 is inclined and the unloading plate 43 is inclined towards the receiving platform 38. When the bottom of the long rod is higher than the pulley 28, the long rod rolls to the right under the action of the inclined surface of the unloading plate 43.
