Description

Technical Field

[0001] This utility model relates to the field of spring production equipment technology, specifically a quenching device for springs. Background Technology

[0002] As an indispensable key component in many mechanical devices, the performance of springs directly affects the operational stability and reliability of the entire mechanical system. In the spring manufacturing process, quenching is a crucial step, significantly improving key performance indicators such as hardness, strength, and wear resistance, thereby ensuring that the spring possesses sufficient load-bearing capacity and durability in complex and changing working environments.

[0003] Traditional spring quenching methods are mostly manual, requiring workers to immerse each heated spring in the quenching liquid for cooling, and then manually remove and transfer them to a storage location after quenching. This method is not only labor-intensive but also inefficient, making it unsuitable for large-scale production. Furthermore, manual operation makes it difficult to precisely control the spring's residence time and cooling rate in the quenching liquid, easily leading to uneven quenching, inconsistent hardness, deformation, and other problems that severely affect spring quality. In addition, some existing spring quenching devices involve cumbersome and inaccurate adjustments to the spring placement components; and the process of collecting springs after quenching is inconvenient and inefficient, increasing production time and costs. Therefore, we propose a spring quenching device. Utility Model Content

[0004] The purpose of this invention is to provide a quenching device for springs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a quenching box, which contains quenching fluid for quenching springs. Several supporting feet are evenly fixedly installed at the bottom of the quenching box. Several sliding cavities are evenly formed on the side wall of the quenching box. A sliding rod is slidably arranged inside each sliding cavity. An installation plate is fixedly installed at the top end of the sliding rod, and a limit plate is fixedly installed at the bottom end of the sliding rod. A placement frame is fixedly installed at the bottom of the installation plate. A sliding groove is also formed inside the installation plate, in which a slider is slidably arranged. A fixing plate is fixedly installed at the bottom end of the slider. A support mesh plate for use with the placement frame is fixedly installed on the side wall of the fixing plate. A sliding sleeve is slidably arranged inside one of the sliding cavities, with its top end fixedly connected to the installation plate. A threaded rod is also rotatably arranged inside another sliding cavity via a bearing, penetrating the sliding sleeve and threadedly connected to it.

[0006] Preferably, a bidirectional screw is rotatably mounted in the groove inside the mounting plate via a bearing, the bidirectional screw passing through the sliders on both sides and being threadedly connected to the sliders on both sides.

[0007] Preferably, the quenching box is further provided with a second driving cavity. A second worm is rotatably mounted inside the second driving cavity via a bearing. The threaded rod passes through the cavity wall of the second driving cavity and extends into the second driving cavity. A second worm wheel is mounted on the threaded rod inside the second driving cavity via a key connection. The second worm wheel meshes with the second worm.

[0008] Preferably, a first driving cavity is also provided on one side of the mounting plate. A first worm is rotatably arranged inside the first driving cavity via a bearing. The bidirectional screw passes through the side wall of the first driving cavity and extends into the first driving cavity. A first worm wheel is connected to the bidirectional screw inside the first driving cavity, and the first worm wheel meshes with the first worm.

[0009] Preferably, a first motor is fixedly mounted on the outer wall of the mounting plate, and the power output shaft of the first motor is fixedly connected to the first worm gear through a coupling.

[0010] Preferably, a second motor is fixedly installed on the side wall of the quenching box, and the power output shaft of the second motor is fixedly connected to the second worm gear through a coupling.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By driving the second worm to rotate through the second motor, the threaded rod is rotated through the worm gear transmission, which in turn drives the sliding sleeve to move the mounting plate and the placement frame up and down, realizing the function of quickly putting the spring into the quenching box for quenching and quickly taking the spring out. This greatly reduces labor intensity, improves production efficiency, and can better meet the needs of large-scale production. By driving the first worm to rotate through the first motor, the bidirectional screw is rotated through the worm gear transmission, which drives the sliders on both sides to move the support mesh plate to both sides, so that the quenched spring automatically falls into the storage box below. The collection process is convenient and efficient, reducing production time and cost.

[0012] In addition, the support feet at the bottom of the quenching box provide stable support for the entire device, ensuring stable quenching operation. At the same time, the worm gear transmission has a self-locking function, which can limit the position of the components after adjustment, preventing components from becoming loose or shifting, thus improving the reliability of the device and extending its service life.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: such as Figures 1-5 The spring quenching device shown includes a quenching box 1, which contains quenching fluid for quenching the spring. Several sliding cavities 3 are evenly distributed on the side wall of the quenching box 1. A sliding rod 4 is slidably disposed within each sliding cavity 3. A mounting plate 6 is fixedly installed at the top end of the sliding rod 4, and a placement frame 7 is fixedly installed at the bottom of the mounting plate 6. A sliding groove is also provided inside the mounting plate 6, and a slider 8 is slidably disposed within the groove. A fixing plate 10 is fixedly installed at the bottom end of the slider 8. A support mesh plate 11, which cooperates with the placement frame 7, is fixedly installed on the side wall of the fixing plate 10. In actual use, when the spring needs to be quenched... During the process, the worker places the heated spring into the placement frame 7, and under the action of the slide rod 4, the placement frame 7 moves into the quenching box 1, so that the quenching liquid inside the quenching box 1 can be used to quench the spring. After quenching, under the action of the slide rod 4, the placement frame 7 is removed from the quenching box 1, and the storage box for storing the spring is placed on top of the quenching box 1. At this time, moving the slider 8 to both sides will move the support mesh plate 11 to both sides, so that the quenched spring inside the placement frame 7 falls into the storage box, thereby completing the collection of the quenched spring and improving the working efficiency of the device.

[0021] Several support feet 2 are evenly fixedly installed at the bottom of the quenching box 1. The support feet 2 ensure the stability of the quenching device during actual use, thereby ensuring the quality of subsequent quenching. A limit plate 5 is fixedly installed at the bottom end of the slide rod 4. The limit plate 5 reduces the occurrence of slide rod 4 falling off, thereby ensuring the efficiency of the placement frame 7.

[0022] A sliding sleeve 12 is slidably disposed inside one side of the sliding cavity 3. The top end of the sliding sleeve 12 is fixedly connected to the mounting plate 6. A threaded rod 13 is also rotatably disposed inside one side of the sliding cavity 3 through a bearing. The threaded rod 13 passes through the sliding sleeve 12 and is threadedly connected to the sliding sleeve 12. At this time, rotating the threaded rod 13 can drive the sliding sleeve 12 to move up and down, thereby realizing the function of adjusting the position of the mounting plate 6.

[0023] A bidirectional screw 9 is rotatably mounted in the groove inside the mounting plate 6 via a bearing. The bidirectional screw 9 passes through the two side sliders 8 and is threadedly connected to them. Rotating the bidirectional screw 9 adjusts the position of the support mesh plate 11. A first drive cavity 14 is also provided on one side of the mounting plate 6. A first worm gear 16 is rotatably mounted inside the first drive cavity 14 via a bearing. The bidirectional screw 9 passes through the side wall of the first drive cavity 14 and extends into the first drive cavity 14. A first worm wheel 15 is connected to the bidirectional screw 9 inside the first drive cavity 14. The wheel 15 meshes with the first worm gear 16. At this time, the first worm gear 16 and the first worm wheel 15 can drive the bidirectional screw 9 to rotate, thereby better controlling the position of the support mesh plate 11. In addition, since the worm gear has a self-locking function, the position of the support mesh plate 11 after adjustment can be restricted, thereby ensuring the efficiency of the support mesh plate 11. The first motor 17 is fixedly installed on the outer wall of the mounting plate 6. The power output shaft of the first motor 17 is fixedly connected to the first worm gear 16 through a coupling. At this time, the first motor 17 can drive the first worm gear 16 to rotate.

[0024] The quenching box 1 also has a second drive chamber 18. A second worm gear 20 is rotatably mounted inside the second drive chamber 18 via bearings. A threaded rod 13 passes through the wall of the second drive chamber 18 and extends into the second drive chamber 18. A second worm wheel 19 is keyed to the threaded rod 13 inside the second drive chamber 18. The second worm wheel 19 meshes with the second worm gear 20. Rotating the second worm gear 20 will drive the threaded rod 13 to rotate through the second worm wheel 19, thereby adjusting the position of the placement frame 7. A second motor 21 is fixedly mounted on the side wall of the quenching box 1. The power output shaft of the second motor 21 is fixedly connected to the second worm gear 20 via a coupling. The second motor 21 can drive the second worm gear 20 to rotate.

[0025] Working principle: When the spring quenching device is working, the heated spring is first placed in the placement frame 7. When the position of the placement frame 7 needs to be adjusted, the second motor 21 is started, and its power output shaft drives the second worm 20 to rotate in the second drive cavity 18. The second worm wheel 19, which meshes with the second worm 20, rotates accordingly. The second worm wheel 19 drives the threaded rod 13 to rotate through a key connection. The threaded rod 13 is threadedly connected to the sliding sleeve 12. The sliding sleeve 12 slides in one side of the sliding cavity 3 and its top is fixed to the mounting plate 6, thereby driving the mounting plate 6 to move up and down. The sliding rod 4 at the bottom of the mounting plate 6 slides in the sliding cavity 3. The limiting plate 5 at the bottom of the sliding rod 4 prevents it from falling off. The movement of the mounting plate 6 causes the placement frame 7 to enter the quenching box 1, where the spring is quenched by the quenching liquid.

[0026] After quenching, the second motor 21 is restarted to move the placement frame 7 out of the quenching box 1. The storage box is placed on top of the quenching box 1, and the first motor 17 is started. Its power output shaft drives the first worm gear 16 to rotate in the first drive cavity 14. The first worm wheel 15, which meshes with the first worm gear 16, rotates. The first worm wheel 15 drives the bidirectional screw 9 to rotate in the sliding groove inside the mounting plate 6. The bidirectional screw 9 is threadedly connected to the sliders 8 on both sides. The sliders 8 drive the fixed plate 10 to move. The support mesh plate 11 on the fixed plate 10 cooperates with the placement frame 7. The support mesh plate 11 moves to both sides, and the springs fall into the storage box, completing the collection. The support feet 2 at the bottom of the quenching box 1 ensure the stability of the device during use and ensure the quenching quality.
