[0002] In modern industry, steel pipes, as an important basic material, are widely used in many industries such as petrochemicals, machinery manufacturing, construction engineering, and the automotive industry. The surface quality of steel pipes not only affects their appearance but also has a significant impact on their wear resistance, corrosion resistance, and sealing performance. Blasting, as a processing technology that can significantly improve the surface quality of steel pipes, applies a certain pressure to the surface of the steel pipe, causing plastic deformation of the surface metal, thereby reducing surface roughness and increasing surface hardness and fatigue strength.
[0003] Currently, traditional steel pipe tumbling processing methods have many shortcomings. On the one hand, some processing equipment has a simple structure, making it difficult to accurately control the tumbling pressure and feed speed, resulting in uneven surface quality of the processed steel pipes, which cannot meet the requirements of high precision. For example, in some small processing enterprises, manually operated tumbling equipment is prone to uneven surface quality of the same batch of steel pipes due to differences in the operator's experience and operating force.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] As shown in Figure 1, the steel pipe tumbling processing device of this utility model embodiment includes a processing box 1: a feeding plate 11 is fixedly connected to the top of the processing box 1; a grinding mechanism is provided on the inner wall of the processing box 1; a vibration mechanism is provided inside the processing box 1; a discharge component is provided in the middle of the inner wall of the processing box 1; and a chip collection mechanism is provided at the bottom of the processing box 1. During operation, when the steel pipe needs to be ground, the steel pipe rolls down from the feeding plate 11 into the processing box 1. The steel pipe is ground by the grinding mechanism and then falls to the top of the discharge component. The vibration mechanism is activated, causing the steel pipe processed at the top of the discharge component to roll out of the processing box 1. The dust and debris generated during the grinding process are vibrated and fall into the chip collection mechanism. Through the above structure, the ground steel pipe can be transported out of the processing box 1 by the cooperation of the vibration mechanism and the discharge component, and the dust and debris generated during grinding can also be conveyed downwards, thereby achieving the purpose of centralized processing of grinding dust and debris.
[0025] As shown in Figures 1 and 2, the grinding mechanism includes a first motor 2, a drive shaft 21, a drive gear 22, a driven gear 23, and a grinding roller 24. The first motor 2 is fixedly connected to the side wall of the processing housing 1. The drive shaft 21 passes through the processing housing 1 and is rotatably connected to the output end of the first motor 2. The drive gear 22 is fixedly connected to the other end of the drive shaft 21 closest to the first motor 2. The driven gear 23 is fixedly connected to the other end of the drive shaft 21 furthest from the first motor 2. The drive gear 22 and the driven gear 23 are meshed together. A grinding roller 24 is fixedly connected to the middle of the drive shaft 21. During operation, when the steel pipe falls into the processing box 1, the first motor 2 is started, causing the drive shaft 21 to drive the drive gear 22 to rotate. The driven gear 23 will rotate due to meshing with the drive gear 22, thereby causing a set of grinding rollers 24 to rotate relative to each other, thus completing the grinding of the steel pipe. Through the above structure, the surface roughness, surface hardness and wear resistance are improved by the rolling action, while eliminating minor surface defects such as scratches and burrs, thereby improving the comprehensive performance and appearance quality of the steel pipe.
[0026] As shown in Figure 5, the vibration mechanism includes a second motor 3, a rotating shaft 31, and an eccentric wheel 32. The second motor 3 is fixedly connected to the side wall of the processing box 1. The rotating shaft 31 passes through the side wall of the processing box 1 and is rotatably connected to the output end of the second motor 3. The other end of the rotating shaft 31 is fixedly connected to the eccentric wheel 32. During operation, when the steel pipe is finished and falls to the discharge assembly, the second motor 3 is started, causing it to drive the rotating shaft 31 to rotate, thereby driving the eccentric wheel 32 to make a circular motion, achieving a vibration effect on the discharge assembly. Through the above structure, the discharge assembly can make the processed steel pipe roll out of the processing box 1 through vibration, thereby improving the automation of the processing device.
[0027] As shown in Figures 3 and 4, the discharge assembly includes a discharge plate 4 and a hinge plate 41; the inner wall of the processing box 1 is fixedly connected to the hinge plate 41; the side wall of the hinge plate 41 is hinged to the discharge plate 4; during operation, the discharge plate 4 is vibrated by the movement of the eccentric wheel 32, and then swings upward around the hinge plate 41. Through the above structure, the steel pipe can roll out of the processing box 1 along the inclined slope of the discharge plate 4, and the vibration can transport the dust and debris generated by grinding to the chip collection mechanism below. The device has a simple structure and is easy to operate.
[0028] As shown in Figure 4, the chip collection mechanism includes a chip collection box 5, a handle 51, and a filter screen 52. The chip collection box 5 is slidably connected to the bottom end of the processing box 1. The handle 51 is fixed to the side wall of the chip collection box 5. The filter screen 52 is provided in the middle of the discharge plate 4. During operation, when dust and debris generated from steel pipe grinding falls to the top of the discharge plate 4, they will penetrate the filter screen 52 and fall to the top of the chip collection box 5, thereby pulling the handle 51. Through the above structure, all dust and debris generated in the processing box 1 can be collected in the chip collection box 5. After processing, they can be cleaned uniformly, which improves the practicality of the processing device.
[0029] As shown in Figure 1, the processing box 1 has a discharge port 6 on its side wall; a dustproof bristle 61 is fixedly connected to the middle of the discharge port 6; during operation, after the steel pipe is ground, it rolls out of the processing box 1 through the discharge port 6, and the dustproof bristle 61 prevents dust and debris from falling to the outside. The above structure can achieve the purpose of sealing the steel pipe during grinding, thereby preventing the dust and debris from spreading.
[0030] As shown in Figure 1, the grinding roller 24 can be replaced according to the size of the steel pipe to be ground. During operation, when steel pipes of different diameters need to be tumble-finished, the grinding roller 24 is replaced. The above structure can meet the high-precision industrial requirements, adapt to steel pipes of different specifications, realize batch automated production, and improve processing efficiency.
[0031] During operation, when the steel pipe needs to be ground, it rolls from the feed plate 11 into the processing box 1. The pipe is ground by the grinding mechanism and then falls onto the top of the discharge assembly. The vibration mechanism is activated, causing the processed steel pipe to roll out of the processing box 1. Dust and debris generated during the grinding process are vibrated and fall into the chip collection mechanism. Through this structure, the grinding-finished steel pipe can be transported out of the processing box 1 by the vibration mechanism and the discharge assembly, and the dust and debris generated during grinding can be conveyed downwards, thus achieving centralized processing of the grinding dust and debris. When the steel pipe falls into the processing box... When the steel pipe is polished, the first motor 2 is started, causing the drive shaft 21 to drive the drive gear 22 to rotate. The driven gear 23 rotates due to its meshing with the drive gear 22, thereby causing a set of grinding rollers 24 to rotate relative to each other, thus polishing the steel pipe. Through the above structure, the surface roughness, surface hardness, and wear resistance are improved by the rolling action, while eliminating minor surface defects such as scratches and burrs, thereby improving the overall performance and appearance quality of the steel pipe. When the polished steel pipe falls to the discharge assembly, the second motor 3 is started, causing the rotating shaft 31 to rotate, thereby causing the eccentric wheel 32 to perform a circular motion, achieving a vibration effect on the discharge assembly. Through the above structure, the steel pipe can be polished. The material assembly vibrates the processed steel pipe, causing it to roll out of the processing box 1, thus improving the automation of the processing device. The discharge plate 4 is vibrated by the movement of the eccentric wheel 32, and then swings upward around the hinge 41. This structure allows the steel pipe to roll out of the processing box 1 along the inclined slope of the discharge plate 4. The vibration also conveys the dust and debris generated during grinding to the lower chip collection mechanism. The device has a simple structure and is easy to operate. When the dust and debris generated during steel pipe grinding falls to the top of the discharge plate 4, it penetrates the filter screen 52 and falls to the top of the chip collection box 5, which then pulls the handle 51. This structure allows the steel pipe to roll out of the processing box... All dust and debris generated inside the body 1 are collected in the chip collection box 5 and cleaned uniformly after processing, which improves the practicality of the processing device. After the steel pipe is ground, it rolls out of the processing box 1 through the discharge port 6, and the dustproof bristles 61 prevent dust and debris from falling to the outside. The above structure can achieve the purpose of sealing the steel pipe during grinding, thereby preventing the dust and debris from spreading. When it is necessary to perform tumbling processing on steel pipes of different diameters, the grinding roller 24 is replaced. The above structure can meet the high-precision industrial requirements, adapt to steel pipes of different specifications, realize batch automated production, and improve processing efficiency.
