Technical Field

[0001] This utility model belongs to the field of steel pipe processing technology, and specifically relates to a descaling device for steel pipe processing. Background Technology

[0002] During the steel pipe manufacturing process, the oxide scale generated on the inner surface of the steel pipe due to oxidation usually needs to be removed, which is called surface descaling. Descaling equipment is usually used to descale the surface of the steel pipe.

[0003] Descaling equipment removes the oxide layer from the surface of steel pipes by rinsing them with water guns. However, current descaling equipment cannot be adjusted in size and cannot adapt well to steel pipes of different sizes. In addition, there is a lack of protective measures after rinsing, and some steel pipes still show oxidation after rinsing. Utility Model Content

[0010] Furthermore, a cylinder rod and a telescopic rod are provided between the fixed rings, and the cylinder rod is electrically connected to the regulator.

[0011] Furthermore, a second connecting pipe is provided inside the fixing rings on both sides, the second connecting pipe is connected to the first connecting pipe, and a rinsing plate is connected to the second connecting pipe.

[0012] Furthermore, the flushing plate is disposed on the inner side of the two fixing rings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The adjustable flushing assembly facilitates the processing of steel pipes of different sizes.

[0015] By setting up a coating component after the rinsing component process, a layer of oil film is applied to the processed steel pipe to protect it and prevent further oxidation, thus providing better protection for the steel pipe. Attached Figure Description

[0024] Please see Figures 1 to 5 A descaling device for steel pipe processing includes a processing box 10; the processing box 10 is used to process steel pipes 101, and a rinsing tank 20 is provided on the top of the processing box 10. The rinsing tank 20 is filled with rinsing liquid for rinsing the steel pipes 101. Processing ports 11 are provided on both sides of the processing box 10 for feeding and discharging the steel pipes 101. Slide grooves 12 are provided on both sides of the processing ports 11. An mounting plate 13 is provided on the upper left side of the processing box 10, and a drive motor 131 is mounted on the mounting plate 13. The rotating shaft of the drive motor 131 extends to the slide groove 12. A drive shaft 132 is provided on the slide groove 12. The drive shaft 132 is connected to the output shaft of the drive motor 131 for transmission. The rotation of the drive motor 131 drives the drive shaft 132 to rotate. The drive shaft 132 is slidably connected to the slide groove 12.

[0025] The drive shaft 132 extends from the left end to the right end of the processing box 10. The drive shaft 132 is designed with pressure roller 133, conveyor shaft 134 and pressure roller 2 137 in sequence from left to right. The rotation of the drive shaft 132 drives the pressure roller 133, conveyor shaft 134 and pressure roller 2 137 to rotate. The steel pipe 101 to be processed enters from the right side, is transported into the processing box 10 by pressure roller 2 137, and is slowly transported to the other side of the processing box 10 by the rotation of the pressure rollers 2 137 on both sides.

[0026] A hydraulic cylinder 14 is provided on the other side of the processing box 10. The hydraulic rod 141 of the hydraulic rod 14 is connected to the transmission shaft 132. The distance between the two transmission shafts 132 can be adjusted by the hydraulic rod 141 to accommodate steel pipes 101 of different sizes, which is convenient for processing.

[0027] A flushing assembly 15 is provided between the second pressure roller 137 and the first pressure roller 133. The flushing assembly 15 is used to flush the steel pipe 101. The flushing assembly 15 includes two fixing rings 151. The two fixing rings 151 are connected by an adjuster 152 at the top. The distance between the two fixing rings 151 is adjusted by the adjuster 152 to accommodate steel pipes of different diameters.

[0028] A connecting pipe 153 is provided at the top of the regulator 152, which is connected to the rinsing tank 20 to guide the rinsing liquid in the rinsing tank 20 into the fixing ring 151. A cylinder rod 154 and a telescopic rod 155 are provided between the two fixing rings 151. The cylinder rod 154 is electrically connected to the regulator 152, and the regulator 152 controls the cylinder rod 154 to adjust the distance between the two fixing rings 151. A connecting pipe 156 is provided inside the two fixing rings 151, and the connecting pipe 156 is connected to the connecting pipe 153. The rinsing liquid enters the connecting pipe 156 from the connecting pipe 153. A rinsing plate 157 is connected to the connecting pipe 156 and is located inside the two fixing rings 151. The rinsing plate 157 is used to rinse and descale the steel pipe 101.

[0029] A coating cotton 135 is installed on the conveyor shaft 134 between the first pressure roller 133 and the second pressure roller 137. Several spray nozzles 136 are installed on the conveyor shaft 134. Cooling oil is installed above the conveyor shaft 134. When the conveyor shaft rotates, the cooling oil drips onto the coating cotton 135, making the coating cotton 135 fully soaked in cooling oil for subsequent coating. The coating cotton 135 comes into contact with the rinsed steel pipe 101 to coat the surface of the steel pipe 101, covering the surface of the steel pipe 101 with an oil film to prevent the steel pipe 101 from oxidizing again and to protect the steel pipe 101. The cooling oil is collected through the several spray nozzles 136 on the conveyor shaft 134. When the spray nozzles 136 are facing upward, they are used to receive the dripping cooling oil. When the conveyor shaft 134 rotates, the cooling oil flows out from the spray nozzles 136 to re-wet the coating cotton 135.

[0030] The working principle and usage process of this utility model are as follows: First, the steel pipe 101 to be processed enters from the right side and is transported into the processing box 10 by the second pressure roller 137. It is slowly transported to the other side of the processing box 10 by the rotation of the second pressure roller 137 on both sides. The rinsing liquid in the rinsing tank 20 is introduced into the fixing ring 151. The rinsing plate 157 set on the fixing ring 151 rinses and descales the steel pipe 101. After rinsing, the steel pipe 101 is transported forward and comes into contact with the coating cotton 135. The coating cotton 135 is used to coat the surface of the steel pipe 101 after rinsing, covering the surface of the steel pipe 101 with an oil film to prevent the steel pipe 101 from oxidizing again and to protect the steel pipe 101.
