Description

Technical Field

[0001] The invention relates to the technical field of polishing devices, and in particular to a steel pipe flap wheel polishing device and a polishing method thereof. Background Art

[0002] Polishing of steel pipes is not only to improve the appearance of the surface, but also to improve its performance, such as durability and corrosion resistance. The surface of the polished steel pipe is smoother and less prone to scale accumulation, which can prevent the surface of the pipe from being corroded, thereby extending its service life. In addition, polishing can also form an invisible protective film, which can better isolate the chemical reactions of active molecules such as water and air, making the molecular structure of the steel pipe more and more solid, so that it can better adhere to the surface of the steel pipe, enhance its stainless properties, and make the application cycle more durable.

[0003] It should be noted that the flap wheel polishing machine is a commonly used equipment for steel pipe polishing. During polishing, the steel pipe is placed on the placement rack, and then the steel pipe is pushed to make the flap wheel polish the steel pipe. However, during the steel pipe polishing, since there are no protective measures, once the steel pipe accidentally jumps out, the flap wheel will continue to rotate, causing the jumped steel pipe to be continuously hit, which can easily cause the steel pipe to be bounced off and cause injuries to the staff. At the same time, when the steel pipe is taken out after polishing, there are also no protective measures, which can easily cause the staff's hands to be injured by the flap wheel due to misoperation or mistouch, posing a huge safety hazard.

[0037] In summary, the working principle of a steel pipe flap wheel polishing device provided by an embodiment of the present invention, that is, the polishing method using the steel pipe flap wheel polishing device is as follows: When grinding the steel pipe, the rotating gear ring 602 is rotated, so that the rotating gear ring 602 synchronously drives the multiple driving gears 612 to rotate, and then the driving gear 612 drives the rotating push-pull frame 608 to rotate through the driving shaft 611, and the rotating push-pull frame 608 drives the pushing frame 606 to move through the pushing-pull shaft 609, so that the pushing frame 606 drives the positioning clamping plate 603 to be recovered, and the positioning clamping plate 603 slides on the installation sleeve 601 through the clamping frame 604, and the clamping spring 610 is stressed, so that when the rotating gear ring 602 is rotated, the four positioning clamping plates 603 are separated from each other, and the steel pipe is placed between the four positioning clamping plates 603, and then the rotating gear ring 602 is loosened, and the multiple clamping frames 604 can be driven under the rebound force of the multiple clamping springs 610 to drive the multiple positioning clamping plates 603 to reset and clamp the steel pipe, so that the steel pipe can automatically complete the positioning and be constrained during grinding, which can ensure the position of the steel pipe and the grinding quality at the same time; Furthermore, when the steel pipe is being polished, if it accidentally jumps out, the displacement angle of the steel pipe is large, so that the steel pipe squeezes any one or more positioning clamps 603, thereby driving the clamping frame 604 at the corresponding position to move, so that the clamping frame 604 drives the driving frame 707 to move through the wedge-shaped push block 708, and the driving frame 707 moves horizontally in the limiting groove 709 through the moving plate 710. At the same time, the movement of the driving frame 707 drives the linkage rod 711 to move, so that the linkage rod 711 moves in the extrusion driving groove 712, thereby driving the linkage The column 706 rotates, and then the linkage column 706 drives the flip frame 701 to flip through the flip shaft 704. At this time, the flip frame 701 drives the driving motor 9 to flip, so that the driving motor 9 drives the thousand-blade polishing wheel 2 away from the steel pipe, and at the same time triggers the emergency stop button 713 to turn off the polishing machine to avoid further expansion of the danger; it should be noted that, the wedge-shaped push block 708 maintains a certain distance from the driving frame 707 in the initial state to avoid the problem of the driving motor 9 rotating due to slight vibration of the steel pipe, thereby ensuring the normal progress of the polishing work; Furthermore, when grinding, the staff steps on the pressure frame 811 with their feet to drive the two lifting rods 805 to move downward synchronously. The lifting rods 805 move vertically in the lifting slot 808 through the lifting block 809, so that the lifting rods 805 drive the rotating rod 804 to rotate through the adapter shaft 806. At the same time, the adapter shaft 806 slides in the adapter slide slot 807. The rotation of the rotating rod 804 drives the rotating plate 802 to rotate through the installation shaft 803. At this time, the rotating plate 802 drives the protective cover 801 to flip over and cover the end of the Qianye polishing wheel 2. This can effectively avoid the problem of accidental contact between the staff and the Qianye polishing wheel 2 when the steel pipe is taken away after grinding is completed, thereby ensuring the safe progress of the grinding work.
