Description
Technical Field
[0001] The present application relates to the field of metal processing technology, and in particular to a high-efficiency steel pipe polishing device. Background Art
[0002] In the field of mechanical manufacturing and processing, steel pipes are a commonly used foundational component, widely used in numerous industries, including construction, bridges, and mechanical equipment. With the rapid development of various industries, the requirements for steel pipe quality and production efficiency are also increasing. High-quality steel pipe polishing is particularly critical in applications where high surface finish and internal diameter accuracy are required, such as precision machinery manufacturing and aerospace. A good polishing process not only improves the corrosion and wear resistance of steel pipes, but also ensures their precise fit with other components, thereby enhancing the performance and reliability of the entire mechanical equipment.
[0003] In order to meet the demand for steel pipe grinding, various methods have been adopted in the existing technology. A common practice is to use external surface grinding equipment alone, and grind the outer surface of the steel pipe by means of grinding wheels, grinding belts and other tools to remove impurities such as oxide scale and burrs on the surface and improve the smoothness of the outer surface. There are also some equipment specifically for grinding the inner diameter of the steel pipe, usually using a rotating grinding head or grinding rod to penetrate into the inside of the steel pipe for grinding to ensure the dimensional accuracy and surface quality of the inner hole. However, most of these grinding methods are carried out separately, that is, the outer surface is polished first, and then the inner diameter is polished, or vice versa. This step-by-step operation method is more common in actual production and has become a traditional grinding process.
[0004] A drawback of existing technology is that existing steel pipe grinding equipment cannot achieve the goal of grinding and polishing both the inner bore and outer surface of a steel pipe on the same device. This results in multiple clamping and sequence changes during the grinding process, which greatly wastes time and labor costs, resulting in low steel pipe grinding efficiency and difficulty meeting the needs of large-scale production and efficient manufacturing.

[0029] The present application is further described in detail below with reference to the accompanying drawings.
[0030] In the description of the invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the invention.
[0031] The present application embodiment discloses a high-efficiency steel pipe polishing device, referring to Figure 1 、 Figure 2 and Figure 3 , including a frame 3, a storage rack 4, an internal grinding mechanism and an external grinding mechanism. The external grinding mechanism is arranged on the frame 3, and the external grinding mechanism includes an external grinding assembly, a discharging assembly and an adjustment assembly. The external grinding assembly includes an external grinding shaft 21, and a plurality of grinding wheels 22 are fixedly arranged on the external grinding shaft 21. The grinding wheel 22 is a grinding wheel that can effectively remove impurities such as oxide scale and burrs on the outer surface of the steel pipe. The discharging mechanism includes a discharging wheel 23 and a driven offset wheel 24. There are multiple discharging wheels 23 and driven offset wheels 24. The surface of the discharging wheel 23 and the driven offset wheel 24 is provided with a rubber layer to increase the friction with the steel pipe, which can better drive the discharging of the steel pipe. The inclination angle of the driven offset wheel 24 can be adjusted according to actual needs to guide the discharging of the steel pipe more smoothly. The multiple discharge wheels 23 are coaxial and driven to rotate by a motor, and the multiple driven offset wheels 24 are coaxial and all tilted at a certain angle toward the discharge direction of the steel pipe. The steel pipe is placed between the discharge wheel 23 and the driven offset wheel 24 during grinding.
[0032] Reference Figure 2 and Figure 3The adjustment assembly includes an adjustment cylinder 25 and an adjustment arm 28. The adjustment cylinder 25 is fixed to the frame 3. The output shaft of the adjustment cylinder 25 is movably connected to the adjustment arm 28. One end of the adjustment arm 28 is rotatably connected to the frame 3, and the other end is fixedly provided with a downward pressure cylinder 26. The output shaft of the downward pressure cylinder 26 is rotatably connected to the outer grinding shaft 21 through a sleeve 27. The adjustment cylinder 25 drives the outer grinding wheel 22 to grind the steel pipe from the upper side. The adjustment cylinder 25 is used to precisely control the position and pressure of the outer grinding wheel 22, while the downward pressure cylinder 26 can further adjust the grinding force of the outer grinding wheel 22 on the steel pipe. The motor drives the discharge wheel 23 to rotate, driving the steel pipe to move between the discharge wheel 23 and the driven offset wheel 24. At the same time, the adjustment cylinder 25 drives the adjustment arm 28, causing the outer grinding wheel 22 to grind the outer surface of the steel pipe from the upper side. The downward pressure cylinder 26 can adjust the grinding force in a timely manner to ensure the grinding effect.
[0033] Reference Figure 1 The internal grinding mechanism is arranged in the discharge direction of the frame 3, and the external grinding mechanism grinds the outer surface of the steel pipe while discharging. The inner surface of the discharged section of the steel pipe is then ground by the internal grinding mechanism. The internal grinding mechanism includes a stand 1, on which a track 11 is provided. In the present application, the track 11 can be a straight track 11 or a track 11 with a certain curvature to meet different grinding requirements. The internal grinding mechanism also includes a trolley 12, and a rail wheel 13 is installed at the bottom of the trolley 12 so that the trolley 12 can move along the length direction of the stand 1. A grinding shaft 14 is provided on the trolley 12, and a grinding brush 15 is provided on the grinding shaft 14. The trolley 12 moves along the track 11 of the stand 1, driving the grinding shaft 14 and the grinding brush 15 to enter the interior of the steel pipe. The motor drives the grinding shaft 14 to rotate, so that the grinding brush 15 grinds the inner surface of the steel pipe.
[0034] Reference Figure 1 and Figure 2 The storage rack 4 is used to store the steel pipes to be polished, and a loading assembly for loading is provided between the storage rack 4 and the frame 3. A plurality of rack rods 41 are provided on the storage rack 4. The rack rods 41 are inclined toward the frame 3 to form a slope. The rack rods 41 are made of square steel pipes. The inclination angle of the slope can be adjusted according to the weight and rolling characteristics of the steel pipe, so that the steel pipe placed on the rack rod 41 will roll along the slope toward the frame 3. The end of the rack rod 41 is also provided with a stopper 42 for limiting the steel pipe. The stopper 42 can prevent the steel pipe from rolling excessively and falling. The storage rack 4 is convenient for storing the steel pipes to be polished, and uses the slope to make the steel pipe automatically roll toward the frame 3, thereby improving the convenience of loading.
[0035] Reference Figure 1 、 Figure 2 and Figure 3The loading assembly includes a mounting plate 43, on which a swing shaft 45 is rotatably mounted, and on which a plurality of swing rods 47 are fixedly mounted. A lifting handle 48 is provided at one end of the swing rod 47 close to the frame rod 41. The lifting handle 48 is configured as a structure with an arc surface to better lift the steel pipe. The lifting handle 48 is configured with a certain deadweight so that the swing rod 47 will naturally deflect toward the lifting handle 48. The plurality of swing rods 47 are interlaced with the frame rod 41. A limit rod 44 is fixed to the mounting plate 43 for limiting the swing amplitude of the swing rod 47. A limit rod 44 is provided at each end of the swing rod 47. One limit rod 44 can keep the swing rod 47 horizontal, and the other limit rod 44 can prevent the swing rod 47 from swinging excessively, thereby ensuring the accuracy of loading. The two ends of the swing shaft 45 are respectively fixed with a protruding rod 46, which is placed on the outside of the two mounting plates 43. The rotation of the swing shaft 45 drives the swing rod 47 to swing, and the lifting handle 48 lifts the steel pipe on the frame rod 41 and transports it to the external grinding mechanism. The limit rod 44 limits the swing amplitude of the swing rod 47, and the telescopic rod 5 abuts against the protruding rod 46.
[0036] Reference Figure 4 The external grinding mechanism also includes a telescopic rod 5, one end of which is fixedly connected to the sleeve 27 and the other end is in contact with the protruding rod 46. A spring 51 and a pressure sensor 52 are installed in the telescopic rod 5. The telescopic rod 5 is configured as two telescopic tubes that can slide against each other. The spring 51 and the pressure sensor 52 are installed in one of the telescopic tubes. The spring 51 can provide a certain buffering force and elastic force, and the pressure sensor 52 can monitor the pressure of the telescopic rod 5 so as to adjust the feeding action according to the pressure situation.
[0037] In addition, the frame 3 is equipped with multiple feed rollers 31 in the discharge direction. Above these feed rollers 31 is a pressure roller 32 that moves up and down via a pneumatic cylinder. In this application, the feed rollers 31 are rubber wheels to reduce friction during steel pipe discharge. The pressure of the pressure roller 32 on the steel pipe is adjusted by a pneumatic cylinder to ensure smooth and stable discharge.
[0038] The working principle of this embodiment is as follows: steel pipes to be polished are placed on a rack 41 in advance. Because rack 41 is tilted, the steel pipes placed on rack 41 roll toward block 42 and are arranged in sequence. The steel pipes are loaded by a loading assembly. Specifically, the loading process, combined with the polishing process, is divided into three stages.
[0039] The first stage is the initial state, with rocker arm 47 held horizontally, and one end of protruding rod 46 abutting telescopic rod 5. Limiting rod 44 limits rocker arm 47 to a horizontal position. Lifting handle 48 is positioned between and below the two racking rods 41, ensuring it does not contact the steel pipes on the racking rods 41.
[0040] When the loading process enters the second stage, the adjustment cylinder 25 drives the adjustment arm 28 downward. The telescopic rod 5 follows the adjustment arm 28 and presses down on one end of the protruding rod 46, causing the rocker arm 47 to swing and contact one of the stop rods 44, specifically the one closest to the frame 3. The lifting handle 48 is then raised, lifting the steel pipe closest to the stop 42 to a height sufficient to allow the pipe to pass over the stop 42 and roll along the surface of the rocker arm 47 toward the frame 3. At this point, the spring 51 within the telescopic rod 5 is not yet compressed, maintaining a length sufficient to ensure that the distance between the top of the rocker arm 47 and the grinding wheel 22 allows the pipe to pass smoothly, allowing it to roll between the discharge wheel 23 and the driven offset wheel 24.
[0041] When the feeding process enters the third stage, which primarily involves grinding with the grinding wheel 22, the steel pipe enters the grinding position (i.e., between the discharge wheel 23 and the driven offset wheel 24). The downward pressure cylinder 26 drives the outer grinding shaft 21 downward, thereby compressing the spring 51. Because the rocker arm 47 abuts the limit rod 44 during the second stage, as the outer grinding shaft 21 moves downward, the telescopic rod 5 continues to press down on the protruding rod 46, reducing the length of the telescopic rod 5 and reducing the distance between the top of the rocker arm 47 and the grinding wheel 22. As the outer grinding shaft 21 moves downward, the grinding wheel 22 contacts the outer surface of the steel pipe, and the pressure detected by the pressure sensor 52 continues to increase. The signal feedback from the pressure sensor 52 controls the downward pressure of the grinding wheel 22 on the steel pipe, thereby controlling the degree of grinding of the steel pipe by the grinding wheel 22.
[0042] When the steel pipe enters the grinding process, as the discharge wheel 23 continues to rotate, under the setting of the driven offset wheel 24, the steel pipe will rotate and move toward the discharge direction. During this process, the grinding wheel 22 continuously grinds the surface of the steel pipe.
[0043] The inner grinding mechanism is arranged in the discharge direction of the frame 3. When the polished section of the steel pipe is discharged, the steel pipe will first pass through the material-smoothing roller 31. The height of the material-smoothing roller 31 is preset in advance so that the steel pipe passing through the material-smoothing roller 31 can be accurately plugged into the grinding shaft 14. At this time, the steel pipe will be polished by the outer grinding mechanism while being discharged. The trolley 12 is used to adjust the position of the grinding shaft 14 so that the grinding shaft 14 is inserted into the steel pipe. The grinding shaft 14 is driven to rotate by the motor, and the grinding brush 15 grinds and polishes the inside of the steel pipe.
[0044] After the outer surface of the steel pipe is polished, a section of the steel pipe will remain on the material-smoothing roller 31. The cylinder drives the pressing roller 32 to press and fix one end of the steel pipe. The trolley 12 moves toward the steel pipe, causing the polishing shaft 14 to move further to polish the unpolished area inside the steel pipe.
[0045] After the inside and outside of the steel pipe are polished, the trolley 12 moves away from the steel pipe to pull out the polishing shaft 14. After the steel pipe loses the support of the polishing shaft 14, the end of the steel pipe toward the polishing shaft 14 will tilt downward. At this time, the downward pressure roller 32 still presses the other end of the steel pipe to slow down the speed at which the steel pipe tilts downward. Then the downward pressure roller 32 moves upward, and the steel pipe slides off the material-guiding roller 31 to achieve the unloading of the steel pipe.
[0046] The equipment then controls the adjustment cylinder 25 to raise the adjustment arm 28, causing the spring 51 to reset. Under the weight of the lifting handle 48, the rocker arm 47 returns to its original position and abuts against the other stopper 44, restoring the rocker arm 47 to a horizontal position. The lifting handle 48 moves down to the bottom of the frame rod 41, and the steel pipe rolls toward the stopper 42. The grinding process then begins for the next steel pipe.
[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
