Description
An automatic lubrication spraying device for the hot extrusion process of aluminum bars Technical Field
[0001] This utility model relates to the field of spraying equipment technology, specifically to an automatic lubrication spraying device for the hot extrusion process of aluminum rods. Background Technology
[0002] The automatic lubrication spraying device in the hot extrusion process of aluminum bars is a device used to automatically spray a release agent on the end face of aluminum bars. Its main purpose is to reduce the adhesion between the aluminum bars and the extrusion pad, improve extrusion efficiency and reduce manual labor intensity. This device is usually installed next to the aluminum bar conveying track. It detects the stagnation point of the aluminum bars through infrared sensors and automatically starts the spraying process after a preset delay time.
[0003] The automatic lubrication spraying device in the hot extrusion process of aluminum bars is usually sprayed before the aluminum bars are extruded. Specifically, after the aluminum bars are cut, they are conveyed to the stagnation point in front of the extrusion chamber of the extrusion equipment to wait for extrusion. At this time, the infrared sensor of the spraying equipment will detect the presence of the aluminum bars and start the spraying device after a preset delay time to spray the release agent evenly on the end face of the aluminum bars. The purpose of this is to form a release layer before the aluminum bars come into contact with the extrusion bar to prevent the aluminum bars from sticking to the extrusion bar during the extrusion process.
[0004] Before hot extrusion of aluminum bars, in order to ensure that an effective isolation layer is formed between the aluminum bars and the extrusion rod during the extrusion process, a release agent needs to be sprayed all over the end face of the aluminum bars. However, if the rotation and position of the aluminum bars cannot be precisely controlled, it will not only lead to uneven or excessive spraying of the release agent, increasing production costs, but also affect the quality and efficiency of the subsequent extrusion process due to the uneven isolation layer, and may even cause the aluminum bars to stick to the extrusion rod, damaging the equipment. Therefore, an automatic lubrication spraying device for the hot extrusion process of aluminum bars is proposed to address the above problems. Summary of the Invention

[0030] Please refer to Figures 1-7. This utility model provides a technical solution:
[0031] An automatic lubrication spraying device for hot extrusion of aluminum bars includes a storage tank 1, a water pump 2, and a nozzle 3. A transmission component 5 is fixedly connected to the bottom of the storage tank 1. A drive support component 4 is fixedly connected to one side of the transmission component 5. A second rotating component 7 and a first rotating component 6 are installed at one end of the drive support component 4. The drive support component 4 includes a frame plate 41. The right side of the frame plate 41 is fixedly connected to the housing of a servo motor 42. A rotating rod 43 is fixedly connected to the end of the main shaft of the servo motor 42. A first synchronous pulley 44 is fixedly connected to the outside of the rotating rod 43. A toothed belt 45 is sleeved on the outside of the first synchronous pulley 44. A vertical plate 46 is rotatably connected to the outside of the first synchronous pulley 44. The transmission component 5 includes a base plate 51. A hydraulic rod 57, an outer plate 56, and a sliding plate 54 are fixedly connected to the top of the base plate 51 in sequence. A conveyor roller 55 is rotatably connected to the inside of the sliding plate 54. The second rotating component 7 and the first rotating component 6 are located between the conveyor roller 55. The inside of the vertical plate 46 is rotatably connected to the outside of the second rotating component 7.
[0032] As a further implementation of this solution, a support column 52 and a guide rod 53 are fixedly connected to the top of the base plate 51. The top of the support column 52 is fixedly connected to the bottom of the storage box 1. A sliding hole is opened on the inner side of the slide plate 54. The guide rod 53 is slidably connected to the inner side of the sliding hole of the slide plate 54. With the above settings, the conveying roller 55 can be moved downward. The first rotating component 6 and the second rotating component 7 support the aluminum rod, providing a stable support foundation for the precise flipping and position control of the aluminum rod, thereby ensuring the smooth progress of the subsequent spraying process.
[0033] As a further implementation of this solution, the inner side of the storage tank 1 is hollow, and a through hole is opened on the inner side of the storage tank 1 near the water pump 2. The through hole of the storage tank 1 is connected to the water inlet of the water pump 2, and the water outlet of the water pump 2 is connected to the inner side of the nozzle 3. Through the above settings, the release agent can be smoothly transported inside the device, ensuring that the release agent can reach the spraying area in a timely and accurate manner, so as to achieve uniform spraying on the end face of the aluminum rod, effectively prevent the aluminum rod from sticking to the extrusion rod, and improve the extrusion efficiency and product quality.
[0034] As a further implementation of this solution, the second rotating assembly 7 includes a sleeve 71. A spring 72 and a first gear ring 73 are fixedly connected to the inner side of the sleeve 71. One end of the spring 72 is fixedly connected to the outer side of the passive rotating column 74. A second gear ring 75 and a second synchronous pulley 76 are fixedly connected to the outer side of the passive rotating column 74. The sleeve 71 is sleeved on the outer side of the passive rotating column 74, and a gap is provided between the sleeve 71 and the passive rotating column 74. There are multiple second rotating assemblies 7. Through the above arrangement, the second rotating assembly 7 can be in close contact with the aluminum rod and rotate stably. The deformation of the spring 72 plays a buffering role to prevent deformation of the aluminum rod surface, while ensuring the timeliness and stability of the aluminum rod rotation, creating good conditions for the uniform spraying of the release agent.
[0035] As a further implementation of this solution, the upper end of the toothed belt 45 is sleeved on the outside of the second synchronous pulley 76. The first synchronous pulley 44 is rotatably connected to the second synchronous pulley 76 through the toothed belt 45. A limiting groove is opened on the inner side of the passive rotating column 74, and a shaft hole is opened on the inner side of the vertical plate 46. A limiting rotating ring is fixed on the inner side of the shaft hole of the vertical plate 46. The passive rotating column 74 is rotatably connected to the vertical plate 46. Through the above settings, the device can accurately control the flipping and rotation of the aluminum rod, realize the uniform spraying of the release agent, and avoid problems such as uneven spraying caused by component jamming or instability.
[0036] As a further implementation of this solution, a straight hole is provided at the right end of the frame plate 41, the bottom end of the upright plate 46 is fixedly connected to the top end of the frame plate 41, and the top end of the frame plate 41 is fixedly connected to the bottom end of the first rotating component 6. The structure of the first rotating component 6 is the same as that of the second rotating component 7. Through the above settings, the overall structure of the device is more compact and coordinated. The identical structural design of the first rotating component 6 and the second rotating component 7 ensures that the aluminum rod can be uniformly and stably supported and rotated at different positions, further improving the uniformity and accuracy of spraying, and effectively enhancing the performance and reliability of the device.
[0037] Workflow: When spraying release agent onto aluminum rods, the aluminum rods are conveyed to the upper part of the conveyor roller 55 via the existing conveyor track. The hydraulic rod 57 is activated, causing the outer plate 56, slide plate 54, and conveyor roller 55 to move downwards. The slide plate 54 slides on the outside of the guide rod 53, which improves the stability of the slide plate 54 during downward movement. The outer plate 56 and hydraulic rod 57 are located directly below the middle of the conveyor roller 55. As the aluminum rod moves downwards between the conveyor rollers 55, it gradually contacts the sleeve 71 set between the second rotating assembly 7 and the first rotating assembly 6. Upon contact, the sleeve 71 moves downwards, causing multiple springs 72 to deform. This deformation of the springs 72 buffers the downward movement of the sleeve 71, preventing surface deformation of the aluminum rod and ensuring the uniformity of the release agent coating. Simultaneously, the elastic force of the springs 72 ensures stable contact between the sleeve 71 and the outer side of the aluminum rod, guaranteeing timely rotation of the aluminum rod. When the first gear ring 73 engages with the outer side of the second gear ring 75, and the multiple conveying rollers 55 move away from the aluminum rod, the water pump 2 is activated, and the lower end of the storage tank 1... When the solenoid valve in the storage tank 1 is opened, the water pump 2 delivers the release agent inside the storage tank 1 to the nozzle 3, where it is sprayed out in a mist. Simultaneously, the servo motor 42 is activated, driving the rotating rod 43 to rotate. The rotating rod 43 drives the first synchronous pulley 44 to rotate. The first synchronous pulley 44, through the toothed belt 45, drives the second synchronous pulley 76 and the driven rotating column 74 to rotate. The driven rotating column 74, through the second gear ring 75 and the first gear ring 73, drives the sleeve 71 to rotate. The meshing of the second gear ring 75 and the first gear ring 73 allows the sleeve 71 to rotate. Stable rotation is achieved through the friction between the sleeve 71 and the aluminum rod, which in turn drives the aluminum rod to rotate. The friction of the aluminum rod drives the sleeve 71 on the first rotating component 6 to rotate, thus achieving uniform and precise spraying on the surface of the aluminum rod. Based on the above principles, the device can precisely flip the aluminum rod before extrusion, thereby ensuring that the sprayed release agent is evenly distributed and covers the surface of the aluminum rod, reducing the waste of release agent, and preventing the aluminum rod from sticking to the extrusion rod during extrusion, which could damage the equipment. This flipping control method avoids the need for personnel to touch the rod, ensuring the safety of the operation.
