Description

Technical Field

[0001] This utility model belongs to the field of spring processing technology, and specifically relates to a quenching device for spring processing. Background Technology

[0002] The main purpose of spring quenching is to increase the hardness and improve the performance of the spring. Quenching involves heating the spring steel to its austenitizing temperature and then rapidly cooling it to room temperature, causing carbon atoms to form a supersaturated solid solution in the crystal lattice. This supersaturated solid solution undergoes a martensitic transformation in the subsequent process, thus greatly increasing the hardness of the spring steel. Quenched spring steel has high hardness and compressive strength, making it suitable for manufacturing various precision and high-load springs. In addition, quenching treatment can also improve the fatigue resistance and wear resistance of spring steel, allowing it to maintain good performance in various harsh environments.

[0003] In the spring manufacturing process, quenching is one of the key steps to improve spring performance. However, after the spring has been quenched and cooled, it is necessary to manually remove the workpiece from the quenching furnace using tools. This can easily cause injury to the operators, pose a safety hazard, and result in low work efficiency, which cannot meet the needs of high-efficiency production.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a quenching device for spring processing to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a quenching device for spring processing, including a quenching box, a lifting assembly installed in the inner cavity of the quenching box, a moving assembly installed on the lifting assembly, and a driving assembly installed at the upper end of the lifting assembly;

[0008] The quenching chamber is used to quench the spring. The drive assembly can drive the lifting assembly to move. The movement of the lifting assembly can drive the moving assembly to move, so as to transport the spring from the bottom to the top of the quenching chamber through the moving assembly.

[0009] Furthermore, the lifting assembly includes a screw, the lower end of which is rotatably mounted on the bottom of the quenching box. A fixing plate is installed on the inner wall of the quenching box. The upper end of the screw passes through and is rotatably mounted on the fixing plate. Positioning rods are symmetrically mounted on the bottom surface of the fixing plate. The lower ends of the positioning rods are all mounted on the bottom of the quenching box. A reversing gear is mounted on the shaft of the upper end of the screw.

[0010] Furthermore, the drive assembly includes a motor, an mounting plate is installed on one side of the quenching box, the motor is mounted on the mounting plate, a drive shaft is mounted on the motor shaft, one end of the drive shaft can extend through the quenching box into the interior, and a drive gear is mounted on the shaft at one end of the drive shaft inside the quenching box, the drive gear meshing with the reversing gear.

[0011] Furthermore, the moving component includes a moving plate, the four sides of which are in close contact with the inner wall of the quenching box. The moving plate is threaded through and threaded onto the screw, and the moving plate can slide with the positioning rod. A plurality of filter holes are evenly provided on the moving plate.

[0012] Furthermore, a feeding hopper is installed at the upper end of the quenching box, the feeding hopper is connected to the inner cavity of the quenching box, and a cover plate is rotatably installed on the inner wall of the feeding hopper, with a handle installed on the cover plate.

[0013] Furthermore, a discharge pipe is installed at the bottom of the quenching box, the discharge pipe is connected to the inside of the quenching box, and a switch valve is installed on the discharge pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model uses a drive component to drive a lifting component to rotate. The rotation of the lifting component drives a moving component to move, thereby moving the spring that has sunk to the bottom of the quenching box to the top of the quenching box. The spring is no longer immersed in the quenching oil, and the device can automatically remove the spring from the quenching oil, making it easier for workers to handle. This solves the safety hazards and low efficiency of traditional manual handling methods, and improves the production efficiency and product quality of spring quenching operations.

[0016] 2. This utility model uses a drive motor to rotate its screw, which in turn moves a moving plate upward on its positioning rod. This moves the spring, which has sunk to the bottom of the quenching box, to the top of the quenching box, so that it is no longer immersed in the quenching oil. This makes it easier for workers to remove the spring. In this way, the device can autonomously move the spring in the quenching oil to the top of the quenching box, so that it is no longer immersed in the quenching oil, making it easier for manual removal and improving work efficiency.

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a quenching device for spring processing, including a quenching box 1, a lifting assembly 2 installed in the inner cavity of the quenching box 1, a moving assembly 3 installed on the lifting assembly 2, and a driving assembly 4 installed on the upper end of the lifting assembly 2.

[0030] The quenching box 1 is used to quench the spring. The driving component 4 can drive the lifting component 2 to move. The movement of the lifting component 2 can drive the moving component 3 to move, so as to transport the spring from the bottom to the top of the quenching box 1 through the moving component 3.

[0031] In practical use, quenching oil is first poured into the quenching box 1, and then the spring that needs to be quenched is placed in the quenching box 1 to immerse the spring in the quenching oil, thereby quenching it and improving its strength and quality. After the spring has completed the quenching process, the drive component 4 can be activated to drive the lifting component 2 to rotate. The rotation of the lifting component 2 will drive the moving component 3 to move upward, so that the spring that has sunk to the bottom of the quenching box 1 can be moved to the top of the quenching box 1. This way, the spring is no longer immersed in the quenching oil, making it easier for workers to pick up and improving work efficiency.

[0032] This invention enables the lifting component 2 to rotate via the driving component 4. The rotation of the lifting component 2 then moves the moving component 3, thereby moving the spring that has sunk to the bottom of the quenching box 1 to the top of the quenching box 1. The spring is no longer immersed in the quenching oil, thus allowing the device to automatically remove the spring from the quenching oil. This makes it easier for workers to handle, solving the safety hazards and low efficiency of traditional manual handling methods, and improving the production efficiency and product quality of spring quenching operations.

[0033] In one embodiment, the lifting assembly 2 includes a screw 5, the lower end of which is rotatably mounted on the bottom of the quenching box 1. A fixing plate 6 is installed on the inner wall of the quenching box 1. The upper end of the screw 5 passes through and is rotatably mounted on the fixing plate 6. Positioning rods 7 are symmetrically mounted on the bottom surface of the fixing plate 6. The lower ends of the positioning rods 7 are all mounted on the bottom of the quenching box 1. A reversing gear 8 is mounted on the shaft of the upper end of the screw 5.

[0034] The drive component 4 can drive its reversing gear 8 to rotate, thereby driving its screw 5 to rotate on the fixed plate 6. The rotation of the screw 5 drives its moving component 3 to move upward on its positioning rod 7, so that its moving component 3 can transport the spring at the bottom of the quenching box 1 to the top of the quenching box 1, so that it is no longer immersed in its quenching oil, making it easier for workers to pick up, so that the device can independently remove the spring.

[0035] In one embodiment, the drive assembly 4 includes a motor 9, a mounting plate 10 is installed on one side of the quenching box 1, the motor 9 is mounted on the mounting plate 10, a drive shaft 11 is mounted on the shaft of the motor 9, one end of the drive shaft 11 can penetrate through the quenching box 1 and extend into the interior, and a drive gear 12 is mounted on the shaft of one end of the drive shaft 11 inside the quenching box 1, the drive gear 12 meshing with the reversing gear 8.

[0036] By driving the motor 9 on the mounting plate 10, its drive shaft 11 can be rotated, which in turn drives the drive gear 12 to rotate, thereby driving the reversing gear 8 that meshes with it to rotate, so that the screw 5 can rotate.

[0037] In one embodiment, the moving component 3 includes a moving plate 13, which is in close contact with the inner wall of the quenching box 1 on all four sides. The moving plate 13 is threaded through and threaded onto the screw 5, and the moving plate 13 can slide with the positioning rod 7. A plurality of filter holes 14 are evenly provided on the moving plate 13.

[0038] Driven by the screw 5, the moving plate 13 can move upward on its positioning rod 7, thereby moving the spring that has sunk to the bottom of the quenching box 1 to the top of the quenching box 1, so that it is no longer immersed in the quenching oil, making it easier for workers to remove the spring. Furthermore, by installing a filter hole 14 on the moving plate 13, the quenching oil can flow through the filter hole 14 to the lower end of the moving plate 13 when the moving plate 13 moves upward, preventing the moving plate 13 from carrying the quenching oil when it moves. Thus, the device can autonomously move the spring in the quenching oil to the top of the quenching box 1, so that it is no longer immersed in the quenching oil, making it easier for manual removal and improving work efficiency.

[0039] In one embodiment, for the quenching box 1 described above, a feeding hopper 15 is installed at the upper end of the quenching box 1, the feeding hopper 15 communicates with the inner cavity of the quenching box 1, a cover plate 16 is rotatably installed on the inner wall of the feeding hopper 15, and a handle 17 is installed on the cover plate 16.

[0040] When a new spring that needs to be quenched needs to be added to the quenching box 1, the worker can rotate the cover plate 16 by the handle 17, thereby opening the upper opening of the feed hopper 15 so that the spring can be placed in the quenching box 1 through the feed hopper 15. When quenching is performed, the feed hopper 15 can also be sealed by the cover plate 16 for protection and heat preservation.

[0041] In one embodiment, for the quenching box 1, a discharge pipe 18 is installed at the bottom of the quenching box 1, the discharge pipe 18 is connected to the inside of the quenching box 1, and a switch valve 19 is installed on the discharge pipe 18.

[0042] When it is necessary to discharge the quenching oil inside the quenching box 1 to the outside, the valve can be turned to open it, so that the quenching oil can be discharged to the outside through the discharge pipe 18, which makes it easier to replace the quenching oil inside the quenching box 1 and improves its practicality.

[0043] In summary, by utilizing the above-mentioned technical solution of this utility model, quenching oil is first poured into the quenching box 1, then the cover plate 16 is opened, and the spring is placed in the quenching box 1 through the feed hopper 15 to immerse the spring in the quenching oil, thereby quenching it and improving its strength and quality. After the spring has completed the quenching process, the drive motor 9 can drive the drive gear 12 to rotate through the drive shaft 11, thereby driving the reversing gear 8 meshing with it to rotate, so that the screw 5 can rotate, thereby driving the screw 5 to rotate. The rotation of the spring causes the moving plate 13 to move upward on its positioning rod 7, thereby moving the spring that has sunk to the bottom of the quenching box 1 to the top of the quenching box 1, so that it is no longer immersed in the quenching oil. This makes it easier for workers to remove the spring. Furthermore, by installing a filter hole 14 on the moving plate 13, the quenching oil can flow through the filter hole 14 to the lower end of the moving plate 13 when the moving plate 13 moves upward, preventing the moving plate 13 from carrying the quenching oil. Thus, the device can autonomously move the spring in the quenching oil to the top of the quenching box 1, so that it is no longer immersed in the quenching oil, making it easier for manual removal and improving work efficiency.

[0044] Through the above technical solutions: 1. The driving component 4 can drive the lifting component 2 to rotate, and the rotation of the lifting component 2 drives the moving component 3 to move. Thus, the moving component 3 moves the spring that has sunk to the bottom of the quenching box 1 to the top of the quenching box 1, so that it is no longer immersed in the quenching oil. This allows the device to autonomously remove the spring from the quenching oil, making it easier for workers to pick up. This solves the safety hazards and low efficiency problems of traditional manual handling methods, and improves the production efficiency and product quality of spring quenching operations. 2. The driving motor 9 can drive the screw 5 to rotate, and the rotation of the screw 5 drives the moving plate 13 to move upward on its positioning rod 7, thereby moving the spring that has sunk to the bottom of the quenching box 1 to the top of the quenching box 1, so that it is no longer immersed in the quenching oil. This makes it easier for workers to pick up the spring. Thus, the device can autonomously move the spring in the quenching oil to the top of the quenching box 1, so that it is no longer immersed in the quenching oil, making it easier for workers to pick up the spring and improving work efficiency.
