Description

Technical Field

[0001] The invention relates to the technical field of lifting sprocket quenching, and in particular to a continuous quenching device and method based on lifting sprocket workpiece processing. Background Art

[0002] In the existing quenching device for lifting sprocket workpiece (hereinafter referred to as workpiece), during the quenching process of the workpiece, the lifting sprocket is usually placed on the surface of a steel belt and sent into a quenching furnace, which results in one side of the lifting sprocket being unable to directly contact with the heating source, but the heat is conducted to the contact surface through the steel belt. At the same time, there are protrusions and grooves on the surface of the lifting sprocket. Compared with the groove, the protrusion is closer to the heating source, so it is easier to absorb the heat emitted by the heating source, resulting in uneven heating on the surface of the lifting sprocket, affecting the quality of the finished product of the lifting sprocket; For example, the continuous quenching device for the lifting sprocket workpiece disclosed in the announcement number CN108330269A can perform continuous quenching operations, but after the workpiece enters the quenching furnace, one side is blocked by the feed crawler and cannot directly absorb the heat emitted by the heating source, which easily causes uneven heating on the surface of the lifting sprocket. The drum quenching device disclosed in the announcement number CN200949110Y can rotate the drum to be quenched, but this setting cannot perform continuous quenching operations, affecting the overall processing efficiency. At the same time, there are protrusions and grooves on the surface of the lifting sprocket. Compared with the grooves, the protrusions are closer to the heating source, so they are more likely to absorb the heat emitted by the heating source, resulting in uneven heating on the surface of the lifting sprocket. Therefore, a continuous quenching device and method based on lifting sprocket workpiece processing are proposed. Summary of the invention

[0014] The present invention provides a continuous quenching device and method based on the processing of a lifting sprocket workpiece. Compared with the prior art, it has the following beneficial effects: (1) The continuous quenching device and method based on the processing of the lifting sprocket workpiece comprises: a quenching furnace body, a conveying unit, a lifting sprocket, a column, a rotating shaft, a gear, a rack, a support plate, a sliding sleeve, a sealing sleeve, a connecting pipe, a movable rod, a guide rod, a fixed plate, an extrusion plate, a friction pad, a lower sliding rod, and an upper sliding rod. The conveying unit is set as a steel belt conveyor, and the lifting sprocket to be quenched is placed above the conveying unit. The lifting sprocket is conveyed to the inside of the quenching furnace body by the conveying unit for quenching. At the same time, the lifting sprocket can rotate in the quenching furnace body, so that the lifting sprocket can receive the heat emitted by the heating source in the quenching furnace body from multiple directions. , so that the lifting sprocket is heated more evenly and the quality of the lifting sprocket after quenching is improved; as the lifting sprocket rotates during the quenching process, its various parts can be evenly exposed to the heating source, thereby reducing the risk of local overheating or insufficient heating, helping to reduce stress concentration caused by excessive temperature gradients, and thus reducing the possibility of workpiece deformation. The gravity-activated mechanism is automatically clamped when the sprocket is put into place, and can adapt to lifting sprockets of different sizes, reducing production line conversion time, improving production response speed, and improving production efficiency. There is no need to design and purchase special fixtures for each specific size of sprocket, reducing initial equipment investment and maintenance costs.

[0015] (2) The continuous quenching device and method based on the processing of the lifting sprocket workpiece, by arranging a push block, an upper sliding block, a connecting rod, an extrusion block, a spring, a clamping plate, a driven rod, a release rod, and a cross bar, after the lifting sprocket is removed from the quenching furnace body after quenching, the clamping plate releases the clamping of the lifting sprocket, so that the lifting sprocket falls from the clamping assembly into the cooling pool for cooling; the lifting sprocket is released by means of the release rod, which reduces the need for workers to carry high-temperature sprockets and reduces the risk of burns and other work-related injuries. The lifting sprocket is quickly released into the cooling pool as soon as the quenching is completed, ensuring the best cooling time. The time point and position of the release can be accurately controlled to ensure that each sprocket can enter the cooling pool according to the predetermined path, which helps to obtain ideal mechanical properties.

[0023] When in use, the conveyor unit 11 is set as a steel belt conveyor, the lifting sprocket 12 to be quenched is placed above the conveyor unit 11, and the lifting sprocket 12 is transported to the inside of the quenching furnace body 1 through the conveyor unit 11 for quenching operation; Further, by fixing two groups of left and right columns 2 on the surface of the conveyor unit 11, the columns 2 provide support force for the rotating shaft 21, the rotating shaft 21 provides support force for the gear 22, the quenching furnace body 1 provides support force for the rack 23, the gear 22 and the rack 23 are meshed, and the lifting sprocket 12 is installed on the rotating shaft 21.

As the lifting sprocket 12 rotates during the quenching process, all parts of the sprocket 12 are evenly exposed to the heat source, thereby reducing the risk of local overheating or insufficient heating.

[0024] Embodiment 2, the technical solution of this embodiment is different from that of embodiment 1 in that: the clamping assembly further includes: a push block 3, an upper sliding block 31, a connecting rod 32, an extrusion block 33, a spring 34, a pressing plate 35, a driven rod 36, a release rod 37, and a cross bar 38; One end of the push block 3 is fixedly mounted on the top of the guide rod 27 and a slope is provided in the middle; One end of the upper sliding block 31 is slidably inserted into the sliding sleeve 25 and a slope is provided on the top, and the upper sliding block 31 is slidably adapted to the slope of the push block 3; One end of the connecting rod 32 is fixedly mounted on the bottom of the upper sliding block 31, and the connecting rod 32 is approximately Z-shaped; One end of the extrusion block 33 is slidably disposed in the connecting rod 32 to assist in fixing the lifting sprocket 12; One end of the spring 34 is fixedly mounted on the extrusion block 33, and the other end of the spring 34 is fixedly mounted in the connecting rod 32, providing elastic force to the extrusion block 33 toward the side where the extrusion block 33 is located; A rotating shaft is fixedly mounted on one end of the pressing plate 35, and the rotating shaft is hingedly mounted on the extrusion plate 29 through a worm spring, and the side wall of the pressing plate 35 is in sliding contact with the bottom of the extrusion block 33; One end of the driven rod 36 is fixedly mounted on the side wall of the extrusion block 33, and the other end of the driven rod 36 is provided with an inclined surface; One end of the crossbar 38 is fixedly mounted on the driven rod 36 so that the extrusion blocks 33 on both sides can move synchronously; One end of the release rod 37 is provided with an inclined surface matched with the inclined surface of the driven rod 36 , so that the clamping assembly releases the clamping of the lifting sprocket 12 .

[0025] When in use, when the lifting sprocket 12 is placed on the fixed plate 28, the guide rod 27 moves downward, which can synchronously drive the push block 3 to move. The inclined surface in the middle of the push block 3 squeezes the inclined surface at one end of the upper sliding block 31, so that the push block 3 can drive the upper sliding block 31 to move. The support plate 24 provides a supporting force for the sliding sleeve 25. The sliding sleeve 25 and the upper sliding block 31 are slidably matched, so that the upper sliding block 31 can move linearly along the sliding sleeve 25 under the action of external force, and the connecting rod 32 is driven to move by the upper sliding block 31. The connecting rod 32 drives the extrusion block 33 to move, and the extrusion block 33 pushes the clamping plate 35 to move, and the extrusion plate 29 provides a supporting force for the rotating shaft, and the rotating shaft provides a supporting force for the clamping plate 35. At the same time, the clamping plate 35 can rotate around the rotating shaft as the axis, so that the clamping plate 35 can rotate around the rotating shaft as the axis under the action of the extrusion block 33, so that the clamping plate 35 is pressed against the side of the lifting sprocket 12, and the lifting sprocket 12 can be stably placed on the fixing plate 28 through the cooperation between the fixing plate 28, the extrusion plate 29, and the clamping plate 35; Furthermore, the spring 34 provides downward elastic force to the extrusion block 33, and the connecting rod 32 provides support force to the spring. The extrusion block 33 and the connecting rod 32 are slidably matched, so that the extrusion block 33 can move linearly along the connecting rod 32 under the action of the spring 34. The extrusion block 33 provides support force to the driven rod 36. At the same time, the two extrusion blocks 33 in the same row are combined by the cross bar 38, so that after the lifting sprocket 12 after quenching is removed from the quenching furnace body 1, it can be moved between the driven rod 36 and the release rod 37. The sliding adaptation allows the release rod 37 to squeeze the driven rod 36 during the process of the conveyor unit 11 driving the driven rod 36 to move, so that the driven rod 36 moves to the side close to the push block 3. The driven rod 36 simultaneously drives the extrusion block 33 and the cross bar 38 to move, so that the extrusion blocks 33 on both sides simultaneously release the pressure on the clamping plate 35, and the clamping plate 35 rotates around the rotating shaft as the axis under the action of the spiral spring, thereby releasing the pressure on the lifting sprocket 12, allowing the lifting sprocket 12 to fall from the clamping assembly into the cooling pool for cooling.

[0026] Embodiment 3, the technical solution of this embodiment is different from that of embodiment 2, including: an auxiliary component for changing the heat absorption surface is arranged above the conveyor unit 11, and the auxiliary component includes: a power rod 4, a reflection plate 41, a fixing block 42, a movable shaft 43, a mounting seat 44 One end of the power rod 4 is fixedly mounted on the conveyor unit 11 through the column 2 to provide power for the reflector 41 to change its angle; The reflector plate 41 is located on the side of the lifting sprocket 12 and is used to reflect the heat emitted by the heating source in the quenching furnace body 1; One end of the fixing block 42 is fixedly mounted on the back of the reflecting plate 41 to provide support for the reflecting plate 41; One end of the movable shaft 43 is movably arranged in the fixed block 42 through a bearing to provide support for the fixed block 42; One end of the mounting seat 44 is fixedly mounted in the quenching furnace body 1 , and the mounting seat 44 is movably connected to the movable shaft 43 to provide support for the reflector 41 .

[0027] When in use, the quenching furnace body 1 provides support force to the mounting seat 44, the mounting seat 44 provides support force to the movable shaft 43, the movable shaft 43 provides support force to the fixed block 42, and the fixed block 42 provides support force to the reflective plate 41. The infrared radiation emitted by the heating source in the quenching furnace body 1 is reflected back to the lifting sprocket 12 by the reflective plate 41, reducing heat loss to the surrounding environment, thereby improving the overall heating efficiency; Furthermore, the column 2 provides a supporting force for the power rod 4, so that when the conveying unit 11 drives the lifting sprocket 12 that is undergoing quenching operation to move through the column 2, the power rod 4 is driven to move synchronously. During the movement, the power rod 4 slides and abuts against the reflective plate 41, so that the power rod 4 squeezes the reflective plate 41 to move, and the reflective plate 41 and the fixed block 42 are turned around the movable shaft 43, and adapted to the movement of the lifting sprocket 12, so that when each lifting sprocket 12 passes through the reflective plate 41, the reflective plate 41 can be turned with the movement of the lifting sprocket 12, thereby ensuring that each workpiece surface can evenly receive the reflected heat, reducing the risk of local overheating or insufficient heating, and can adjust the reflection angle according to the specific contour of the workpiece to provide more accurate heating distribution, ensuring that each workpiece is in the ideal temperature range during the entire heating process, ensuring that the entire workpiece surface is heated evenly, thereby reducing the risk of deformation caused by uneven temperature, and further improving the finished product quality of the lifting sprocket 12 after quenching.

[0028] In another embodiment different from the aforementioned embodiment, a movable scraper is integrated on the surface of the reflecting plate 41, a movable guide rail is set on the top of the reflecting plate 41, and the scraper is slidably fitted with the movable guide rail. After running for a period of time, in order to avoid the reduction of reflection efficiency caused by the agglomeration of dust and oxides on the surface of the reflecting plate 41, the scraper is controlled to extend a certain distance from the reflecting plate 41 so that the power rod 4 can slide and abut against the scraper when passing through the reflecting plate 41, thereby driving the scraper to slide along the movable guide rail, allowing the scraper to scrape off the dust and oxides on the reflecting plate 41, thereby ensuring the reflection efficiency of the reflecting plate 41 and avoiding the situation where the heat reflected to the lifting sprocket is different due to the different reflection efficiencies between various areas of the reflecting plate 41, thereby causing uneven heating of the lifting sprocket surface and affecting the quality of the finished product.

[0029] The embodiment of the present invention also provides a quenching method applicable to a continuous quenching device based on the processing of a lifting sprocket workpiece, comprising the following steps: S1, fix the lifting sprocket 12 to be quenched on the conveyor unit 11 through a clamping assembly; S2, start the conveyor unit 11 through the control console, and convey the lifting sprocket 12 fixed on the conveyor unit 11 to the quenching furnace body 1 for preheating, heating and heat preservation; S3, during the preheating, heating and heat preservation process, the lifting sprocket 12 is driven to flip by the flip assembly to receive the heat from the heating source in the quenching furnace body 1 at multiple angles; S4, using the reflector 41 in the auxiliary assembly to refract the heat emitted by the heating source in the quenching furnace body 1 to the lifting sprocket 12 being turned over, thereby changing the amount of heat absorbed by the groove of the lifting sprocket 12; S5. After preheating, heating and heat preservation are completed, the lifting sprocket 12 falls from the clamping assembly into the quenching pool.

[0030] The rotation angle of the reflector 41 is between 0° and 60°.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0033] Parallel: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness. Small angular errors are allowed. For example, an assembly error range of less than 10 degrees can be understood as a parallel relationship.

[0034] Vertical: The verticality defined in this application is not limited to an absolute vertical intersection relationship (angle of 90 degrees). It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.
