Description

Technical Field

[0001] This invention belongs to the field of polishing equipment technology, specifically a billet finishing and grinding device for seamless tube production. Background Technology

[0002] Seamless steel pipes are made by piercing a whole round steel bar and have no weld seams on the surface. In the production process of seamless steel pipes, due to the defects on the surface of some round steel billets, finishing and grinding are indispensable pretreatment processes. The purpose is to remove defects such as oxide scale and cracks on the surface of the round steel billet and provide high-quality billets for subsequent piercing and rolling.

[0003] The external cylindrical polishing device is used for the fine finishing and grinding of round steel billets. The external cylindrical polishing device can use a grinding wheel to polish the surface of the round steel billet multiple times. During the polishing process, combustible metal dust will be generated, and static electricity will be generated by the friction between the round steel and the grinding wheel, which will cause the round steel to attract dust. At the same time, a large number of round steels are put into the heating furnace each time. After the round steels enter the high-temperature heating furnace, a large amount of dust can easily cause deflagration, which poses a safety hazard. Summary of the Invention

[0014] A filter cylinder is fixedly connected inside the cylinder, and a hexagonal cylinder is fixedly connected inside the cylinder via a bearing seat.

The bottom end of the hexagonal plate extends into the interior of the hexagonal cylinder, and a fan blade is fixedly connected to the surface of the hexagonal cylinder.

[0015] In the above technical solution, preferably, concave sleeves are fixedly connected to the front and rear sides of the bottom of the guide sleeve, the concave sleeves are fitted onto the surface of the fixing plate, and a protective net is fixedly installed at the bottom of the inner cavity of the cylinder by bolts, the protective net being located at the bottom of the fan blade.

[0016] In the above technical solution, preferably, the fixed ring is provided with a reciprocating transmission mechanism, the reciprocating transmission mechanism includes a reciprocating lead screw, the reciprocating lead screw is fixedly connected to the inside of the rotating gear ring through a bearing seat, a second gear is fixedly connected to the right end of the reciprocating lead screw, a fixed gear ring is fixedly connected to the inside of the fixed ring, the second gear meshes with the fixed gear ring, and a transmission cylinder is movably connected to the surface of the reciprocating lead screw through a connecting rod and a connecting sleeve, the surface of the transmission cylinder is fixedly connected to the inner wall of the movable sleeve.

[0017] In the above technical solution, preferably, the brush sleeve includes an adjusting sleeve, which is slidably connected inside the movable sleeve. An air inlet is provided at the top of the adjusting sleeve, and brush bristles are fixedly connected to the top of the adjusting sleeve.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention uses a motor and gears to drive a rotating gear ring and brush sleeve to clean the surface of a round steel billet. The rotating fan blades create airflow to adsorb impurities, and the filter cartridge filters the impurities. The vortex plate, through springs and slide rods, causes the metal plate to periodically strike the round steel billet, shaking off dust through micro-vibration, thus enhancing the cleaning effect. At the same time, the grounding wire eliminates static electricity in the round steel billet, preventing dust adsorption and achieving the advantages of dust removal and static electricity elimination. This effectively reduces the risk of deflagration in the subsequent heating furnace and lowers safety hazards.

[0023] Furthermore, relying solely on the rotational motion of the brush sleeve to clean round steel billets results in relatively weak cleaning power. It is difficult to completely remove strongly adhering oxide scale and iron filings. However, through the design of the reciprocating transmission mechanism, including the reciprocating lead screw, gear II, and fixed gear ring, the brush sleeve can increase lateral displacement on the basis of rotational cleaning, forming a cross cleaning trajectory that fully covers the surface of the round steel billet, avoiding cleaning blind spots. The friction generated by the reciprocating motion effectively removes stubborn impurities. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] like Figures 1 to 3 As shown, the present invention provides a billet finishing and grinding device for seamless tube production, including a polishing table 1, a polishing device 2 fixedly connected to the rear side of the top of the polishing table 1, and a protective cover 3 hinged to the top of the polishing table 1. The device also includes:

[0037] The rotating cleaning component 4 is located inside the polishing table 1 and is used to clean impurities on the surface of the round steel billet.

[0038] The rotating cleaning component 4 includes a motor 41, which is fixedly connected to the inside of the polishing table 1 via a connecting plate. A fixing ring 42 is provided on the top of the motor 41, and a rotating gear ring 43 is slidably connected inside the fixing ring 42. The top end of the output shaft of the motor 41 passes through the inside of the fixing ring 42 and is fixedly connected to a gear 44, which meshes with the rotating gear ring 43.

[0039] The striking component 45 is located on the right side of the retaining ring 42 and is used to eliminate static electricity generated on the surface of the round steel billet due to friction.

[0040] A flow guide sleeve 46 is provided at the bottom of the motor 41. The front and back sides of the flow guide sleeve 46 are fixedly connected to the inside of the polishing table 1. The front and back sides of the top of the flow guide sleeve 46 are connected to the bottom of the fixing ring 42. A filter device 47 is fixedly installed at the bottom of the flow guide sleeve 46.

[0041] The left side of the rotating toothed ring 43 is connected to a support sleeve 48, and a movable sleeve 49 is slidably connected inside the support sleeve 48. A brush sleeve 410 is fixedly installed inside the movable sleeve 49.

[0042] Specifically, the polishing device 2 is an external cylindrical polishing machine, consisting of a drive motor 41, a belt, a main shaft, and a grinding wheel. Its working principle is as follows: the motor 41 drives the main shaft to rotate via the belt, and the main shaft drives the grinding wheel to polish the surface of the round steel billet; the polishing table 1 consists of a guide wheel and a rotating shaft. The rotating shaft can drive the round steel billet to rotate, and the guide wheel can guide the round steel billet, allowing the round steel billet to move during rotation. Both the polishing device 2 and the polishing table 1 are mature technologies. The motor 41 is a dual-axis motor 41; the left side of the inner wall of the rotating gear ring 43 is provided with teeth, and the rotating gear ring 43 meshes with the gear 44 through the teeth.

[0043] like Figures 3 to 6 As shown, the striking component 45 includes a square sleeve 451, a T-shaped plate 452 is slidably connected inside the square sleeve 451, a grounding wire 453 is fixedly connected to the bottom of the T-shaped plate 452, a spring 454 is fixedly connected to the bottom of the T-shaped plate 452, and the bottom end of the spring 454 is fixedly connected to the bottom of the inner wall of the square sleeve 451.

[0044] A vortex plate 455 is fixedly connected to the right side of the rotating gear ring 43, and a slide rod 456 is fixedly connected to the left side of the T-shaped plate 452. The top of the slide rod 456 contacts the bottom of the vortex plate 455.

[0045] Specifically, when the rotating gear ring 43 rotates, it drives the volute plate 455 to rotate. The rotation of the volute plate 455 drives the T-shaped plate 452 downward to compress the spring 454 through the slide rod 456. After the volute plate 455 rotates one revolution, the slide rod 456 disengages from the volute plate 455, and the spring 454 releases its elastic force instantly, causing the T-shaped plate 452 to quickly return to its original position. This generates a knocking force on the round steel, thereby shaking off the dust and enhancing the dust removal effect. At the same time, the grounding wire 453 contacts the round steel through the T-shaped plate 452, promptly dissipating the static electricity generated by friction and eliminating the risk of dust adsorption.

[0046] like Figure 5As shown, a metal plate 5 is fixedly installed on the top of the surface of the T-shaped plate 452 by bolts, and a metal wheel 6 is slidably sleeved on the surface of the metal plate 5.

[0047] Specifically, the T-shaped plate 452, the metal plate 5, and the metal wheel 6 are all made of conductive metal material. The metal plate 5 is fixed to the top of the T-shaped plate 452 with bolts, which facilitates replacement and height adjustment. When wear occurs, maintenance can be completed quickly. By setting the metal wheel 6, the sliding friction between the T-shaped plate 452 and the round steel can be converted into rolling friction, reducing the friction when the two are in contact, thereby ensuring that the round steel can move smoothly during the hammering process.

[0048] like Figure 8 As shown, the filter device 47 includes a cylinder 471, which is disposed at the bottom of the guide sleeve 46. The top of the cylinder 471 is connected to the bottom of the guide sleeve 46. Fixing plates 472 are fixedly connected to the top of both the front and back sides of the cylinder 471. The top of the fixing plates 472 is connected to the bottom of the guide sleeve 46 by bolts.

[0049] A filter cylinder 473 is fixedly connected inside the cylinder 471. A hexagonal cylinder 474 is fixedly connected inside the cylinder 471 via a bearing seat. The bottom end of the output shaft of the motor 41 passes through to the bottom of the filter cylinder 473 and is fixedly connected to a hexagonal plate 475. The bottom end of the hexagonal plate 475 extends into the interior of the hexagonal cylinder 474. A fan blade 476 is fixedly connected to the surface of the hexagonal cylinder 474.

[0050] Specifically, the cylinder 471 and the guide sleeve 46 are connected by a fixing plate 472, which facilitates the cleaning or replacement of the filter cylinder 473; while the hexagonal plate 475 driven by the motor 41 cooperates with the hexagonal cylinder 474 to drive the fan blade 476 to rotate at high speed, forming a stable airflow, which draws dust into the cylinder 471 for filtration, realizing an integrated operation of cleaning and dust suction at the same time.

[0051] like Figure 8 As shown, concave sleeves 7 are fixedly connected to the front and rear sides of the bottom of the guide sleeve 46. The concave sleeves 7 are fitted onto the surface of the fixing plate 472. A protective net 8 is fixedly installed at the bottom of the inner cavity of the cylinder 471 by bolts. The protective net 8 is located at the bottom of the fan blade 476.

[0052] Specifically, the concave sleeve 7 is made of hard plastic. The concave sleeve 7 can limit the position of the fixing piece 472 and the cylinder 471, improve the stability of the fixing piece 472 and the cylinder 471, and facilitate the user to accurately install and fix the cylinder 471.

[0053] like Figure 7As shown, a reciprocating transmission mechanism 9 is provided inside the fixed ring 42. The reciprocating transmission mechanism 9 includes a reciprocating lead screw 91, which is fixedly connected to the inside of the rotating gear ring 43 through a bearing seat. A gear 92 is fixedly connected to the right end of the reciprocating lead screw 91. A fixed gear ring 93 is fixedly connected inside the fixed ring 42. The gear 92 meshes with the fixed gear ring 93. A transmission cylinder 94 is movably connected to the surface of the reciprocating lead screw 91 through a connecting rod and a connecting sleeve. The surface of the transmission cylinder 94 is fixedly connected to the inner wall of the movable sleeve 49.

[0054] Specifically, the reciprocating transmission mechanism 9 does not require an additional power source. The reciprocating cleaning trajectory of the brush sleeve 410 can be achieved by the rotation of the rotating gear ring 43. This allows the brush sleeve 410 to generate lateral displacement while rotating and cleaning, forming a cross cleaning path that effectively covers the entire surface of the round steel. This avoids cleaning blind spots caused by single rotation and improves the removal efficiency of stubborn impurities.

[0055] like Figures 1 to 4 As shown, the brush sleeve 410 includes an adjusting sleeve 4101, which is slidably connected inside the movable sleeve 49. An air inlet 4102 is provided on the top of the adjusting sleeve 4101, and brush bristles 4103 are fixedly connected to the top of the adjusting sleeve 4101.

[0056] Specifically, when the fan blade 476 rotates to create negative pressure, the airflow can carry dust into the interior of the guide sleeve 46 through the air inlet 4102, and timely adsorb the dust that is peeled off during the brushing process, thereby improving the dust removal efficiency. The bristles 4103 are made of nylon and can effectively remove impurities from the surface of the round steel billet.

[0057] like Figure 2 and Figure 10 As shown, the right side of the guide sleeve 46 is connected to the air inlet sleeve 10, and the top of the polishing table 1 is fixedly inlaid with a perforated sleeve 11. The right end of the air inlet sleeve 10 is connected to the left side of the perforated sleeve 11.

[0058] Specifically, by setting the air intake sleeve 10 and the perforated sleeve 11, the dust in the grinding area can be drawn into the interior of the guide sleeve 46, and then separated by the filter cartridge 473, so as to prevent the dust from spreading near the polishing table 1 and effectively control dust pollution.

[0059] like Figure 5 As shown, a guide plate 12 is fixedly connected to the top right side of the metal plate 5. The guide plate 12 is sleeved on the surface of the metal wheel 6. Microporous sound-absorbing plates 13 are fixedly connected to the front and rear sides of the top of the square sleeve 451.

[0060] Specifically, the guide plate 12 can guide the round steel billet and prevent the round steel billet from colliding with the T-shaped plate 452. At the same time, the microporous sound-absorbing plate 13 can absorb the noise generated by the knocking to a certain extent, improve the noise reduction effect, and improve the workshop working environment.

[0061] like Figures 1 to 4 As shown, the bottom of the movable sleeve 49 is fixedly connected to a screw 14 via a bearing, the bottom end of the screw 14 is fixedly connected to a rotating plate 15, the top surface of the screw 14 is threadedly connected to a screw sleeve 16, and the top end of the screw sleeve 16 is fixedly connected to the top of the inner wall of the adjusting sleeve 4101.

[0062] Specifically, when the screw 14 rotates, the screw sleeve 16 moves up or down along the screw 14. The screw sleeve 16 drives the adjusting sleeve 4101 to rise and fall synchronously within the moving sleeve 49, thereby precisely controlling the contact pressure between the bristles 4103 and the surface of the round steel. At the same time, it facilitates the bristles 4103 to adapt to round steel of different diameters, further improving the cleaning effect.

[0063] Working principle and usage process of this invention:

[0064] First, the user starts the motor 41. The motor 41 drives the gear 1 44 to rotate, which in turn drives the rotating gear ring 43 to rotate. The rotating gear ring 43 drives the adjusting sleeve 4101 to rotate via the moving sleeve 49. The adjusting sleeve 4101 uses the brush bristles 4103 to clean the rotating and moving round steel. When the rotating gear ring 43 rotates, it drives the reciprocating screw 91 to rotate. Since the gear 2 92 meshes with the fixed gear ring 93, the reciprocating screw 91 will rotate on its own axis. The reciprocating screw 91 drives the moving sleeve 49 to move back and forth left and right via the transmission cylinder 94, which in turn drives the adjusting sleeve 4101 and the brush bristles 4103 to clean the round steel by brushing it left and right. The bottom end of the output shaft of the motor 41 drives the fan blade 476 to rotate via the hexagonal plate 475 and the hexagonal cylinder 474. The fan blades 476 expel air downwards, allowing the adjusting sleeve 4101 to draw in impurities. After being guided by the moving sleeve 49 and the fixed ring 42, the filter cylinder 473 filters the impurities. Simultaneously, the rotating toothed ring 43 drives the vortex plate 455 to rotate. The vortex plate 455 pushes the slide rod 456 downwards, and the slide rod 456 drives the T-shaped plate 452 to squeeze the spring 454. After the vortex plate 455 rotates once, the slide rod 456 disengages from the vortex plate 455, and the spring 454 instantly releases its elasticity, causing the T-shaped plate 452 to quickly return to its original position and strike the round steel, thereby shaking off the dust. The grounding wire 453 contacts the round steel through the T-shaped plate 452, promptly dissipating the static electricity generated by friction and eliminating the risk of dust adsorption, thus achieving the effect of dust removal and static electricity elimination.
