Description

Technical Field

[0001] This utility model relates to the field of seamless pipe processing technology, and more specifically, to a stainless steel seamless pipe spraying device. Background Technology

[0002] Stainless steel seamless pipe is a type of stainless steel pipe without weld seams, manufactured through hot rolling or cold drawing processes. It is widely used in various fields, such as chemical, petroleum, pharmaceutical, food processing, and machinery manufacturing. Stainless steel has excellent corrosion resistance and can be used for a long time in various corrosive environments. The manufacturing process of seamless pipe gives it high strength and toughness, enabling it to withstand high pressure and temperature. Stainless steel seamless pipe can maintain good mechanical properties at high temperatures.

[0003] In existing technologies, seamless tubes are often fixed by external clamps. The clamping device usually needs to be in close contact with the seamless tube to ensure that the tube remains stable during the spraying process. These contact points can block the spraying material, causing these areas to be unsprayed. The unsprayed areas may become the starting point of corrosion, affecting the service life of the tube. In the seamless tube spraying process, the lack of a drying device after spraying will result in slow paint drying, which not only prolongs the production cycle, but may also affect the adhesion of the paint and the final coating quality.

[0029] Please see Figures 1-5 A stainless steel seamless pipe spraying device includes a spraying machine body 1, which includes a support base 2. The support base 2 has a rotating shaft 3 and a rotating disk 4. Both the rotating shaft 3 and the rotating disk 4 are equipped with support devices. Each support device includes a support box 5. A first bevel gear 6 is rotatably mounted on one side of the support box 5. A support screw 7 is rotatably mounted on the support box 5. A support rod 8 is threadedly connected to one end of the support screw 7. A support frame 9 and a support pad 10 are mounted on the support rod 8. A second bevel gear 11, which mates with the first bevel gear 6, is mounted on the other end. A drying rack 12 is located on one side of the support base 2. A drive cylinder 13 is provided on the 12, and a drying hood 14 is provided at the output end of the drive cylinder 13. A drying pipe 15 is provided on the drying hood 14, and a drying nozzle 16 is provided on the drying pipe 15. A splined shaft 17 is provided on the rotating shaft 3, and a splined sleeve 18 that mates with the splined shaft 17 is provided on the rotating disk 4. An adjusting rod 19 is provided on the first bevel gear 6. The adjusting rod 19 is slidably disposed on the rotating shaft 3 and the rotating disk 4. An adjusting knob 20 is provided at one end of the adjusting rod 19. A rotating motor 23 is provided on one side of the support base 2. A synchronous belt drive assembly 24 is provided on the motor shaft of the rotating motor 23 and the rotating shaft 3.

[0030] In this embodiment, when clamping and fixing the seamless tube, the position of the rotating disk 4 is moved by the cooperation of the spline shaft 17 and the spline sleeve 18, and the seamless tube is placed on the support device. The adjustment handle is rotated, and the adjustment knob 20 drives the adjustment rod 19 to rotate. The adjustment rod 19 drives the first bevel gear 6 to rotate. The first bevel gear 6 drives the second bevel gear 11 and the support screw 7 to rotate. The support rod 8 is rectangular and can only slide along the rotating shaft 3 and the rotating disk 4. Therefore, the support screw 7 and the support rod 8 rotate relative to each other, driving the support frame 9 and the support pad 10 to support outward and support the inner wall of the seamless tube. Then, the rotating motor 23 is started. The rotating motor 23 drives the rotating shaft 3 and the rotating disk 4 to rotate through the synchronous belt transmission assembly 24, thereby driving the seamless tube to rotate. The synchronous belt transmission assembly 24 ensures precise synchronization between the pulley and the driven component by meshing the teeth on the pulley and the teeth on the synchronous belt.

[0031] Please see Figures 4-5As one embodiment of spraying and drying seamless pipe: a hot air blower 21 is provided on the drying rack 12, and a connecting hose 22 is provided between the output end of the hot air blower 21 and the drying pipe 15. A moving device is provided on one side of the support frame 9, and a spray gun 25 is provided on the moving device. The moving device includes a moving frame 26, a moving groove 27 is provided on the moving frame 26, a moving block 28 is slidably provided in the moving groove 27, the spray gun 25 is set on the moving block 28, a moving screw 29 is rotatably provided in the moving groove 27, the moving screw 29 is threadedly connected to the moving block 28, and a moving motor 30 is provided at one end of the moving screw 29.

[0032] More specifically, when spraying the seamless tube, the spray gun 25 is started. The spray gun 25 is connected to a paint feeding device. The spray gun 25 is existing technology, and its working principle will not be described in detail here. The moving motor 30 is started, which drives the moving screw 29 to rotate. The moving screw 29 drives the moving block 28 to move along the moving frame 26, thereby moving the position of the spray gun 25. It works in conjunction with the rotating seamless tube to spray the seamless tube. After the spraying is completed, the drive cylinder 13 is started, which drives the drying hood 14 to move downward. The hot air blower 21 is started. The hot air blower 21 can be equipped with a filter screen to prevent dust from entering. The hot air blower 21 flows hot air into the connecting hose 22 and the drying pipe 15, and sprays it out through the drying nozzle 16 to dry the paint sprayed on the seamless tube, thereby improving the drying and spraying efficiency of the paint.

[0033] In summary, during the use or operation of the overall equipment: when clamping and fixing the seamless tube, the position of the rotating disk 4 is moved by the cooperation of the spline shaft 17 and the spline sleeve 18, and the seamless tube is placed on the support device. Rotating the adjustment handle, the adjustment knob 20 drives the adjustment rod 19 to rotate, the adjustment rod 19 drives the first bevel gear 6 to rotate, the first bevel gear 6 drives the second bevel gear 11 and the support screw 7 to rotate. The support rod 8 is rectangular and can only slide along the rotating shaft 3 and the rotating disk 4. Therefore, the support screw 7 and the support rod 8 rotate relative to each other, driving the support frame 9 and the support pad 10 to support outward and support the inner wall of the seamless tube. Then, the rotating motor 23 is started. The rotating motor 23 drives the rotating shaft 3 and the rotating disk 4 to rotate through the synchronous belt drive assembly 24, which in turn drives the seamless tube to rotate. The synchronous belt drive assembly 24 ensures precise synchronization between the pulley and the driven component by the meshing of the teeth on the pulley and the teeth on the synchronous belt.

[0034] When spraying the seamless tube, the spray gun 25 is started. The spray gun 25 is connected to a paint feeding device. The spray gun 25 is existing technology, and its working principle will not be described in detail here. The moving motor 30 is started, which drives the moving screw 29 to rotate. The moving screw 29 drives the moving block 28 to move along the moving frame 26, thereby moving the position of the spray gun 25. It works in conjunction with the rotating seamless tube to spray the seamless tube. After the spraying is completed, the drive cylinder 13 is started, which drives the drying hood 14 to move downward. The hot air blower 21 is started. The hot air blower 21 can be equipped with a filter screen to prevent dust from entering. The hot air blower 21 flows hot air into the connecting hose 22 and the drying pipe 15, and sprays it out through the drying nozzle 16 to dry the paint sprayed on the seamless tube, thereby improving the drying and spraying efficiency of the paint.
