Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of polishing of galvanized pipes, and particularly relates to a polishing device for galvanized pipes. Background Art
[0002] The galvanized layer is a layer of metallic zinc plated on the outer wall of the steel pipe by a hot-dip process. The activity level of zinc and its antioxidant and rust resistance capabilities are superior to those of conventional Q195-Q235 steel. Therefore, the galvanized layer on the outer wall of the steel pipe is a protective layer that delays the oxidation of the steel pipe and extends the pipeline life. When the galvanized pipe is exposed to rain at high temperatures during transportation, the passivation layer on the surface of the zinc layer will be washed away, rendering the passivation effect of the galvanized layer ineffective. During normal production and storage, due to the lack of protection of the passivation layer for the zinc layer, the galvanized layer is extremely prone to oxidation, resulting in white ash or a darkening of the zinc layer. This not only affects the appearance of the product but also shortens the service life of the product. Due to weather and temperature reasons, passivation failure may also occur in the pipes after finished product transportation, storage, or outdoor installation. Therefore, galvanized pipes need to be polished and ground before leaving the factory.
[0003] Although the polishing devices in the prior art can achieve the effect of polishing galvanized pipes, they still have the following technical problems when in use: 1. When polishing galvanized pipes, a certain amount of dust and waste chips will be generated, affecting the polishing environment. Therefore, the workbench needs to be cleaned frequently, which is rather cumbersome and inconvenient; 2. Since galvanized pipes are generally relatively long, when polishing them, the center of gravity of the steel galvanized pipe fittings is likely to be at one end far from the grinding machine tool, causing the steel galvanized pipe fittings to easily tip over, affecting the polishing effect. Therefore, this device still has certain deficiencies.
[0004] Therefore, there is an urgent need for a polishing device for galvanized pipes to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a polishing device for galvanized pipes to solve the problems raised in the above background art.

By providing the polishing wax film applicators 33, a layer of wax can be evenly coated on the outer wall of the galvanized pipe before polishing, thereby achieving a certain effect of isolating moist air, protecting the zinc layer, and delaying the oxidation of the zinc layer. Secondly, the cooperation of the provided rough polishing wheel 31 and fine polishing wheel 32 can perform rough polishing and fine polishing on the galvanized pipe, thereby achieving a more thorough and accurate polishing effect.
[0033] As Figure 1 and Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the pressing component 10 includes a hydraulic cylinder 34 fixedly connected to the side of the dust-proof box 7. The output end of the hydraulic cylinder 34 is provided with a second connecting plate 36. A slide rod 37 is penetrated through the second connecting plate 36. The bottom of the slide rod 37 is connected with a U-shaped connecting plate 38. A spring 39 is sleeved on the outer wall of the slide rod 37. The spring 39 is arranged between the second connecting plate 36 and the U-shaped connecting plate 38. A runner 40 is arranged at the bottom of the U-shaped connecting plate 38. By providing the pressing component 10, when the runner 40 is attached to the galvanized pipe fitting, the U-shaped connecting plate 38 can slide along the slide rod 37 under the elastic force of the spring 39, so that the pressing component 10 is always attached to the galvanized pipe fitting, avoiding the situation that the center of gravity of the galvanized pipe fitting is at one end far from the grinding machine tool, resulting in the tipping of the galvanized pipe fitting, thereby achieving a better polishing effect on the galvanized pipe.
[0034] Specifically, when the polishing equipment for galvanized pipes is in use: place the galvanized pipe fitting to be polished from the right end of the equipment, and then adjust the distance between the transmission components 3 according to the size of the galvanized pipe fitting. When adjusting, rotate the handle 16 to drive the bidirectional screw rod 14 connected thereto to rotate, which will drive the roller assembly 5 and the roller assembly 6 to move relatively or away from each other, so as to adjust the distance between the roller assembly 5 and the roller assembly 6, thereby realizing the loading of galvanized pipe fittings of different sizes. Set the distance between the transmission devices 3 and close the dust-proof box 7. With the cooperation of the set dust-proof box 7, when polishing it, it can inhibit the dispersion of dust to a certain extent, and secondly, it can also avoid the splashing of debris. The generated debris can be collected and uniformly processed through the set debris collection groove. Start the second driving motor 41 to drive the roller 27 to rotate, and cooperate with the set roller 22 to convey the galvanized pipe to be processed. When the galvanized pipe reaches the bottom of the pressing component 10 through the transmission device 3, start the hydraulic rod 35 to descend. When the runner 40 at its bottom is attached to the galvanized pipe fitting, the U-shaped connecting plate 38 will slide along the slide rod 37 under the elastic force of the spring 39, so that the pressing component 10 is always attached to the galvanized pipe fitting, avoiding the situation that the center of gravity of the galvanized pipe fitting is at one end far from the grinding machine tool, resulting in the tipping of the galvanized pipe fitting, so as to ensure a better polishing effect on the galvanized pipe. When the galvanized pipe fitting reaches in front of the rough polishing wheel 31, first, the polishing wax is evenly attached to the surface of the galvanized pipe fitting through the polishing wax laminator 33. Then start the motor 30 to drive the rough polishing wheel 31 to rotate to perform rough polishing on the galvanized pipe. Immediately afterwards, when the galvanized pipe fitting reaches in front of the fine polishing wheel 32, the polishing wax also needs to be evenly attached to the surface of the galvanized pipe fitting through the polishing wax laminator 33 first and then finely polished by the fine polishing wheel 32. Among them, the polishing wax can play a role in isolating moist air, protecting the zinc layer and delaying the oxidation of the zinc layer. Finally, the galvanized pipe fitting completely passes through the dust-proof box 7, and the polishing work of the galvanized pipe fitting is completed. Finally, the debris collected in the debris collection groove 11 is regularly cleaned through the chip removal port.
