Description

Technical Field

[0001] The invention relates to the technical field of steel pipe production and processing, in particular to a high-efficiency grinding and cleaning device for steel pipes. Background Art

[0002] Steel pipes have a hollow cross-section, with their length significantly greater than their diameter or circumference. They are categorized by cross-sectional shape into round, square, rectangular, and special-shaped steel pipes. Based on the production process, they are divided into seamless and welded steel pipes. Seamless steel pipes are further categorized into hot-rolled and cold-rolled (drawn), while welded steel pipes are further categorized into straight-seam welded pipes and spiral-seam welded pipes. Steel pipes are not only used for transporting fluids and powdered solids, exchanging heat, and manufacturing mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture building structural grids, pillars, and mechanical supports reduces weight, conserves metal, and enables factory-based, mechanized construction.

[0003] In the process of steel pipe processing, grinding and cleaning is an important process. The complete grinding and cleaning operation includes brushing, grinding and flushing processes.

[0004] Patent No. CN220128323U discloses a cold-drawn grinding and cleaning device for seamless steel pipes, comprising a base, on which a brushing mechanism, a grinding mechanism and a cleaning mechanism are arranged. The brushing mechanism comprises a brushing trough, a feeding port is provided at the top of the brushing trough, an electric push rod is provided on one side of the brushing trough, a discharge port is provided on the other side of the brushing trough, a brushing cylinder is provided at the discharge port, bristles are provided on the inner wall of the brushing cylinder, and a guide slide is provided below the brushing cylinder. , so that the seamless steel pipe that has been brushed rolls to the grinding mechanism; through the set brushing mechanism, grinding mechanism and cleaning mechanism, when the seamless steel pipe is pushed out of the brushing cylinder, the bristles remove impurities on its surface, and the guide slide guides it to the arc-shaped groove of the placement table. The clamping block clamps the seamless steel pipe and rotates it on the surface of the grinding sheet for grinding. At the same time, the cleaning nozzle sprays cleaning liquid to flush the seamless steel pipe, realizing the continuous processing of the brushing, grinding and cleaning processes in the grinding and washing process of the seamless steel pipe, with high grinding and washing efficiency and reduced labor burden of workers.

[0005] However, the above technical solution only utilizes the bristles of the cleaning brush barrel, and there is a problem that the cleaning process is not efficient enough. In addition, the grinding sheet fixed to the placement table by the elastic layer cannot adapt to a variety of steel pipes for grinding.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] (1) A high-efficiency grinding and cleaning device for steel pipes, wherein the stud can slide along the screw barrel, thereby changing the radial position of the adjustment plate on the main barrel, and the adjacent adjustment mechanisms are axially staggered and symmetrical, so that the adjustment mechanisms at adjacent positions do not hinder each other, thereby adapting to cleaning of steel pipes of various radii, thereby improving the adaptation range.

[0033] (2) A high-efficiency grinding and cleaning device for steel pipes, which pushes the rods through the support rod assembly to cause the base to bend and deform, and the push block plays the role of pushing the base toward the axis. Then, through the deformation of the base and the bristles, the contact angle and pressure between the bristles and the surface of the steel pipe are changed, the working state of the bristles is flexibly adjusted, and the adjustable performance is improved.

[0034] (3) A high-efficiency grinding and cleaning device for steel pipes. When the surface of the steel pipe is uneven, the raised parts will squeeze the base to reduce its bending degree, and the pressure of the brush bristles will be high at this time; the concave parts will make the base bend more, and the bristles will open more, increasing the contact area, thereby adapting to the surface of the steel pipe for cleaning and improving the cleaning uniformity.

[0035] (4) A high-efficiency grinding and cleaning device for steel pipes, which expands the axial cleaning area of ​​the brush by means of the spirally arranged bristles on the base. At the same time, the high-speed rotating bristles drive the surrounding air to form a spiral airflow field, generating a negative pressure zone at the root of the bristles, actively sucking the dust and oil particles peeled off from the surface of the steel pipe during the cleaning process, thereby improving the cleaning effect.

[0036] (5) A high-efficiency grinding and cleaning device for steel pipes, wherein when the adjustment mechanism of the cleaning brush assembly moves radially to fit the steel pipe, the support rollers of the support roller assembly are synchronously scaled with the steel pipe axis as the center through the guide rod and the adjustment mechanism, and the pressure of the sensor-sensing spring is synchronously driven through the wiring to the grinding roller assembly to reach the position of fitting the steel pipe, so that the support roller assembly is arranged in advance to support the steel pipe to be ground, thereby improving the grinding stability.

[0037] (6) A high-efficiency grinding and cleaning device for steel pipes, which links the adjustment mechanism and the support roller assembly through a guide rod, thereby utilizing the rotation of the main cylinder to drive the synchronous rotation of the grinding cylinder, and coordinating with the self-rotation of the grinding roller to perform precision grinding on the outer side of the steel pipe. The power of the grinding cylinder rotation is transmitted through the main cylinder, and the flushing cylinder of the flushing mechanism also borrows the rotational power of the grinding cylinder through the connecting bar, thereby improving the synchronization of work and effectively saving power performance.

[0038] (7) A high-efficiency grinding and cleaning device for steel pipes, wherein when the grinding thickness of the steel pipe and the radius difference between the grinding roller and the support roller are completed at the same time, the grinding pressure of the grinding roller is gradually reduced, thereby forming a limit on the grinding thickness, and the thickness of the grinded steel pipe is consistent, thereby improving the grinding and cleaning quality.

[0039] (8) A high-efficiency grinding and cleaning device for steel pipes, wherein the flushing mechanism is designed with a sticking roller, and the angle of the connecting arm is reasonably adjusted by the motor of the main shaft, so that the sticking roller is used to adaptively support the steel pipe after grinding, thereby improving the central axis stability of the steel pipe during grinding and cleaning, avoiding the deflection of the steel pipe, and improving the grinding and cleaning quality.

[0040] (9) A high-efficiency grinding and cleaning device for steel pipes, in which a flushing head is arranged on the outer side of the roller in the direction of travel. The flushing heads on both sides are used to flush the steel pipe by leveraging the flushing cylinder, thereby avoiding dead corners for drainage below and preventing impurities from accumulating at the bottom of the steel pipe, thereby improving the flushing cleanliness.

[0041] A high-efficiency grinding and cleaning device for steel pipes uses a sticking roller to support the steel pipe and uses the sticking roller to accurately locate the position of the flushing head. Both ends of the flushing head extend out of the flushing cylinder, which can perform preliminary flushing of the steel pipe in the early stage of support, avoiding damage to the steel pipe caused by grinding powder held by the sticking roller, and improving the protection of the steel pipe.

[0042] (10) A high-efficiency grinding and washing device for steel pipes, which flushes the steel pipes again through a flushing head in the later stage of support, avoiding the obstruction of the sticking roller, so that the flushing head can fully flush the steel pipes, avoid impurity residue, and improve the flushing quality.

[0083] The working principle of the present invention is as follows:

[0084] Start the rotator 202 embedded on the main barrel 201, and drive the screw barrel 203 to rotate through the belt 204. Under the limiting action of the through hole 205 and the limiting rod 304, the stud 303 can slide along the screw barrel 203, thereby changing the radial position of the adjustment plate 301 on the main barrel 201, and the adjacent adjustment mechanisms 3 are axially staggered and symmetrical, so that the adjustment mechanisms 3 at adjacent positions will not hinder each other, and thus adapt to steel pipes of various radii for cleaning, thereby improving the adaptation range.

[0085] A moving mechanism 5 is provided in the outer cylinder assembly, the screw ring 502 is screwed to the thread 207, and the inclination of the support rod 504 is adjusted by the electric shaft of the rod seat 503, so that the suction cup 505 docks and adsorbs the opposite rod 412, and the cleaning mechanism 4 is installed in the groove 302, wherein one end of the base 404 is fixed by the first connecting head 406 and the cleaning brush bin 401, and the other end of the base 404 can slide along the moving groove 402 through the second connecting head 408. When the screw ring 502 is rotated, the ring 501 moves along the axial direction of the outer cylinder 206, and the opposite rod 412 is pushed by the support rod assembly to cause the base 404 to bend and deform. The push block 410 plays the role of pushing the base 404 toward the axis, and then through the deformation of the base 404 and the bristles 405, the contact angle and pressure of the bristles 405 and the surface of the steel pipe are changed, the working state of the bristles 405 is flexibly adjusted, and the adjustable performance is improved.

[0086] After the base 404 is convex, it is deformed so that it cannot rotate around its axis. The steel pipe contacts the bristles 405 on the base 404 to clean the steel pipe. When the surface of the steel pipe is uneven, the convex part will squeeze the base 404 accordingly to reduce its bending degree. At this time, the pressure of the bristles 405 is high; the concave part makes the base 404 bend more, and the bristles 405 open more, increasing the contact area, thereby adapting to the surface of the steel pipe for cleaning and improving the uniformity of cleaning.

[0087] After the steel pipe is preliminarily cleaned by the cleaning assembly, the spiral ring 502 is moved outward along the outer cylinder 206 to restore the base 404 to its original shape. At this time, the contact pressure between the bristles 405 and the steel pipe is reduced, and the base 404 can rotate around its axis. During the rotation of the main cylinder 201, the cleaning mechanism 4 contacts the steel pipe, thereby causing the base 404 to rotate around its axis. The axial cleaning area of ​​the cleaning is expanded by the bristles 405 spirally arranged on the base 404. At the same time, the high-speed rotating bristles 405 will drive the surrounding air to form a spiral airflow field, and a negative pressure area will be generated at the root of the bristles 405, which will actively suck the dust and oil particles peeled off from the surface of the steel pipe during the cleaning process, thereby improving the cleaning effect.

[0088] There are two supporting roller assemblies corresponding to the adjusting mechanism 3 symmetrically arranged on the grinding cylinder 601. Grinding roller assemblies embedded in the grinding cylinder 601 are evenly arranged between the two supporting roller assemblies. A guide rod 606 for linkage is provided between the supporting roller assembly and the adjusting mechanism 3. When the adjusting mechanism 3 of the cleaning assembly moves radially to fit the steel pipe, the supporting roller 602 of the supporting roller assembly cooperates with the adjusting mechanism 3 through the guide rod 606 to synchronously scale around the axis of the steel pipe, and the pressure of the spring 604 is sensed by the sensor 605 and synchronously driven to the position of fitting the steel pipe through the connection 610, so that the supporting roller assembly is arranged in advance to support the steel pipe to be polished, thereby improving the grinding stability.

[0089] The adjusting mechanism 3 and the supporting roller assembly are linked by the guide rod 606, so that the rotation of the main cylinder 201 drives the grinding cylinder 601 to rotate synchronously, and the outer side of the steel pipe is precisely ground in coordination with the rotation of the grinding roller 608. The power of the rotation of the grinding cylinder 601 is transmitted through the main cylinder 201. In addition, the flushing cylinder 703 of the flushing mechanism 7 also borrows the rotational power of the grinding cylinder 601 through the connecting bar 704, thereby improving the synchronization of the work and effectively saving power performance.

[0090] Grinding roller assemblies embedded in the grinding cylinder 601 are evenly arranged between the two supporting roller assemblies. The supporting roller assembly moves synchronously with the adjusting mechanism 3 driven by the guide rod 606, and then transmits its radial movement data to the cylinder 607 of the grinding roller assembly through the sensor 605 arranged on the supporting roller assembly, so that the grinding roller 608 of the grinding roller assembly is adapted to contact the outside of the steel pipe. The radius of the grinding roller 608 is larger than the radius of the support roller 602. Therefore, before grinding, the pressure between the grinding roller 608 and the outside of the steel pipe is relatively large. As the grinding progresses, the pressure between the grinding roller 608 and the outside of the steel pipe gradually decreases. When the grinding thickness of the steel pipe is equal to the radius difference between the grinding roller 608 and the support roller 602, the grinding is completed at the same time. The grinding pressure of the grinding roller 608 gradually decreases, thereby forming a limitation on the grinding thickness. The thickness of the polished steel pipe is consistent, thereby improving the grinding quality.

[0091] The flushing mechanism 7 is designed with a sticking roller 707, which reasonably adjusts the angle of the connecting arm 706 through the motor of the main shaft 705, so that the sticking roller 707 is used to adaptively support the polished steel pipe, improve the central axis stability of the steel pipe during grinding and washing, avoid steel pipe deflection, and improve the grinding quality.

[0092] A flushing head 710 is set in the direction of travel of the outer side of the roller 707. The flushing head 710 on both sides is used to flush the steel pipe by leveraging the flushing cylinder 703, which can avoid the dead corner of drainage below, prevent impurities from accumulating at the bottom of the steel pipe, and improve the flushing cleanliness.

[0093] The steel pipe is supported by the sticking roller 707, and the position of the flushing head 710 is accurately positioned by the sticking roller 707. The flushing cylinder 703 is extended from both ends of the flushing head 710, which can perform preliminary flushing of the steel pipe in the early stage of support, avoiding damage to the steel pipe caused by the grinding powder pressed by the sticking roller 707, and improving the protection of the steel pipe.

[0094] In the later stage of support, the steel pipe is flushed again by the flushing head 710, avoiding the obstruction of the sticking roller 707, so that the flushing head 710 can fully flush the steel pipe, avoid impurity residue, and improve the flushing quality.

[0095] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
