Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe processing, in particular to a high-speed polishing device for the surface of a steel pipe. Background Art

[0002] Steel pipes are not only used to transport fluids and powdered solids, exchange heat, and manufacture mechanical parts and containers, but they are also an economical steel material. Using steel pipes to manufacture building structure grids, pillars and mechanical supports can reduce weight, save 20-40% of metal supports, and realize factory-based mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​protective coating, saving investment and maintenance costs.

[0003] During long-term use or storage, steel pipes may have certain rust or burrs on their surface. Generally, a polishing device is used to polish the steel pipes. The traditional mechanical polishing method, that is, a polishing machine is used to move back and forth on the surface of the steel pipe to polish the surface of the steel pipe. This method is slow and inefficient, and is difficult to apply to large-scale continuous polishing scenarios, and the polishing quality is uneven.

[0004] The Chinese patent with the authorization announcement number CN218746984U discloses a high-speed polishing device for steel pipe surface, including a bottom plate, a square column fixedly connected to the top of the bottom plate, a working plate fixedly connected to the top of the square column, a connection box fixedly connected to the bottom of the working plate, a polishing mechanism arranged inside the connection box, a fixing mechanism arranged on the top of the working plate, a grinding wheel arranged on one side of the polishing mechanism, the fixing mechanism comprising a first motor, a first rotating shaft fixedly connected to the right side of the first motor, a limiting groove arranged on the top of the working plate, a stabilizing plate slidably connected inside the limiting groove. The high-speed polishing device for steel pipe surface converts the rotational motion of the threaded barrel into the linear motion of the third threaded rod through the setting of the fixing mechanism, so that the stabilizing plate can be pressed against the inner wall of the steel pipe, thereby achieving the function of fixing the steel pipe, and can replace manual automatic and high-speed grinding and polishing of the steel pipe, thereby improving the polishing efficiency.

[0005] However, the above has the following shortcomings:

DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a high-speed polishing device for the surface of a steel pipe includes a panel 10, on which two symmetrical shaft seats 17 are fixedly connected, two wheel axles 16 are rotatably connected between the two shaft seats 17, one end of one wheel axle 16 is transmission-connected to a first motor 19, three pulleys 15 are evenly distributed and fixedly connected to each wheel axle 16, and rubber belts 13 are transmission-connected between the pulleys 15 respectively located on the two wheel axles 16, the bottom side of each rubber belt 13 is tightly fitted with the panel 10, and a notch 14 is opened on the edge of each rubber belt 13, a polishing component is arranged in the panel 10, and a feeding and discharging component is arranged on the panel 10.

[0035] The multiple steel pipes are pressed into the notch 14 by the circulating rubber belt 13 and passed through the polishing component along with the rubber belt 13, thereby achieving the polishing work of multiple steel pipes at the same time, greatly improving the polishing speed and thus improving the production efficiency.

[0036] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, a first baffle plate 22 is fixedly connected to one end of the panel 10, a feed hopper 12 is fixedly connected to the upper end of the first baffle plate 22, both ends of the feed hopper 12 are fixedly connected to two shaft seats 17 via a bracket 20, a downwardly inclined discharge port 11 is provided on the end of the panel 10 away from the first baffle plate 22, the arc-shaped surface on the inner side of the first baffle plate 22 fits tightly with the three rubber belts 13 and slides relative to each other, and second baffle plates 21 are fixedly connected to both ends of the first baffle plate 22.

[0037] By providing the feed hopper 12 and the first baffle 22 and circulating the rubber belt 13, automatic loading is realized, and after the steel pipe is polished, automatic unloading is realized through the discharge port 11, thereby avoiding the problem of wasting time and manpower in manual loading and unloading.

[0038] like Figure 3 and Figure 6 As shown, the polishing component includes a roller frame 24, and the roller frame 24 is fixedly connected to the lower side of the panel 10. The roller frame 24 and the panel 10 are arranged to be inclined relative to each other. A plurality of belt rollers 29 are rotatably connected inside the roller frame 24, and one end of one of the belt rollers 29 is transmission-connected to a second motor 25. Polishing belts 23 exposed from the surface of the panel 10 are transmission-connected between the plurality of belt rollers 29.

[0039] By means of the polishing belt 23 which is arranged obliquely relative to the panel 10, it is possible to polish the steel pipe along its axis while applying a circumferential force to the steel pipe to make it rotate, thereby achieving a uniform polishing effect on all parts of the steel pipe surface.

[0040] like Figure 4 and Figure 5 As shown, a support plate 18 is fixedly connected between the two shaft seats 17 . The support plate 18 passes through the inner side of each rubber belt 13 . Each support plate 18 fits tightly with the rubber belt 13 and slides relative to it.

[0041] By providing the support plate 18 , the rubber belt 13 is supported during the circulation of the rubber belt 13 , thereby ensuring the smooth operation of the rubber belt 13 and preventing the rubber belt 13 from bending and causing the steel pipe to escape from the notch 14 .

[0042] like Figure 4 and Figure 5 As shown, two groups of slide bars 28 are slidably connected at two intervals between the three rubber belts 13 in the support plate 18, a pressure plate 26 is fixedly connected to the lower side of each group of slide bars 28, and a spring 27 is arranged between each slide bar 28 and the support plate 18 and surrounds the outer side of the corresponding slide bar 28.

[0043] By providing the pressure plate 26 and cooperating with the elasticity of the spring 27, appropriate pressure is applied to the steel pipe during the polishing process, thereby ensuring that the polishing belt 23 and the steel pipe can be in stable contact, thereby improving the polishing efficiency and effect of the steel pipe.

[0044] In this embodiment, initially, the operator connects the power supply and control system of this patent, and then puts the steel pipes to be polished of the same specifications into the feed hopper 12, and places a collecting device under the discharge port 11, and then turns on the power. The first motor 19 drives the three rubber belts 13 to circulate, and the steel pipes in the feed hopper 12 enter the slot 14 one by one under the action of gravity and move with the rubber belt 13. When the rubber belt 13 moves the steel pipe to the first baffle 22, the steel pipe is restricted by the arc surface of the first baffle 22 to prevent it from falling, and the two ends of the steel pipe are restricted by the second baffle 21 to prevent it from moving, and then the steel pipe contacts the panel 10 with the movement of the rubber belt 13.

[0045] Then the rubber belt 13 continues to move and brings multiple steel pipes into the range of the polishing belt 23 one by one. At this time, the second motor 25 drives the polishing belt 23 to rotate at a high speed, and the polishing belt 23 polishes and grinds multiple steel pipes at the same time. Since the polishing belt 23 and the panel 10 are relatively inclined, while polishing the steel pipe along the axial direction of the steel pipe, a circumferential force is applied to the steel pipe to make the steel pipe rotate, so that the surface of the steel pipe is uniformly polished. Then, the polished steel pipe gradually enters the range of the discharge port 11, rolls obliquely downward to leave the slot 14 and enters the collection device.

[0046] Under the circulation of the rubber belt 13 and the grinding and polishing of the polishing belt 23, a continuous, uninterrupted, high-speed and uniform grinding and polishing effect is achieved, thereby improving work efficiency. In addition, by setting the feed hopper 12 and the discharge port 11 to cooperate with the circulation of the rubber belt 13, automatic loading and unloading can be realized simply and effectively, thereby greatly reducing the time and manpower for manual loading and unloading and improving work efficiency.

[0047] In the process of grinding and polishing the steel pipe by the polishing belt 23, the support plate 18 is used to support the rubber belt 13, which can effectively prevent the rubber belt 13 from bending and deforming and causing the steel pipe to detach from the groove 14, thereby ensuring the continuity and stability of the polishing work. In addition, when the polishing belt 23 polishes the steel pipe, the elasticity of the spring 27 is used to make the pressure plate 26 apply a stable pressure to the steel pipe, so that the steel pipe and the polishing belt 23 can be in stable and effective contact, thereby improving the grinding and polishing effect of the polishing belt 23 on the steel pipe.

[0048] Embodiment 2:

[0049] like Figure 7As shown, two groups of plate seats 30 are fixedly connected to the panel 10 near the two shaft seats 17, and elastic plates 31 are fixedly connected between each group of plate seats 30. Polishing strips 32 are fixedly connected to the two sides of the two elastic plates 31 close to each other.

[0050] As a further embodiment, by providing an elastic plate 31 and a polishing strip 32, while the steel pipe passes through the panel 10 and is polished by the polishing belt 23, the two ends of the steel pipe are brought into contact with the polishing strip 32 through the conveyance of the groove 14, and the elasticity of the elastic plate 31 is utilized to make the polishing strip 32 and the two ends of the steel pipe closely and stably contact and rub, and while the steel pipe rotates, the two ends of the steel pipe are polished by the polishing strip 32, thereby further improving the polishing effect of the steel pipe.
