Description

Technical Field

[0001] The utility model relates to the technical field of passivation spraying, in particular to a passivation air ring air pressure regulating mechanism. Background Technique

[0002] The passivation film is a protective oxide film on the metal surface, and its function is to prevent the metal from further corrosion and oxidation. Because the chemical properties of the passivation film are inert and do not react with most elements. The most common passivation films are aluminum oxide on the aluminum surface and chromium trioxide on the stainless steel surface, etc.

[0003] In the prior art, when spraying a passivation film on the surface of a metal pipe material, the air pressure generated by an air pump is used to evenly spread the passivation liquid, resulting in the following disadvantages: The size of the air pressure is also required according to the amount of the passivation liquid. Excessive air pressure may blow off all the passivation liquid and fail to effectively form a passivation film. Too small air pressure will cause too much residual passivation liquid, resulting in the yellowing of the pipe body, increasing the risk of passivation quality problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a passivation air ring air pressure regulating mechanism to solve the problem that the size of the air pressure is also required according to the amount of the passivation liquid. Excessive air pressure may blow off all the passivation liquid and fail to effectively form a passivation film. Too small air pressure will cause too much residual passivation liquid, resulting in the yellowing of the pipe body, increasing the risk of passivation quality problems.

[0005] To achieve the above-mentioned utility model purpose, the utility model adopts the following technical scheme: A passivation air ring air pressure regulating mechanism, including a spraying box, several sliding holes are respectively opened on both sides of the spraying box, a fixed frame is fixed on one side of the spraying box, an air pump is fixed on the top surface of the spraying box, one end of the exhaust pipe of the air pump is fixed with a pressure gauge, and the surface of the exhaust pipe of the air pump is fixedly communicated with an adjusting pipe. Several sleeving holes are opened on the top surface of the fixed frame, the adjusting pipe is fixedly inserted into the sleeving holes, a sleeving ring is fixed at the bottom end of the adjusting pipe, and the central axis of the sleeving ring is on the same straight line as the sliding holes.

[0006] Preferably, two fixing plates are fixed on one side of the spraying box. A driving motor is fixed on one side of the left fixing plate. A rotating hole is opened on one side of the fixing plate. A rotating roller is rotatably arranged between the two fixing plates. Fixing columns are respectively fixed at both ends of the rotating roller, and the fixing columns are rotatably inserted into the rotating holes. One end of the output shaft of the driving motor passes through the left rotating hole and is fixed to one end of the left fixing column.

[0007] Preferably, a heater is fixed on the top surface of the fixed frame, a positioning hole is provided on the top surface of the fixed frame, a warming box is fixed on the inner top surface of the fixed frame, an injection hole is provided on the top surface of the warming box, one end of the heater exhaust pipe passes through the positioning hole and is fixed to the inner wall surface of the injection hole, and two exhaust holes are provided on the inner bottom surface of the warming box.

[0008] Preferably, two fixing holes are provided on the bottom surface of the incubator, and a flow tube is provided below the incubator, and surfaces at both ends of the flow tube are respectively fixed to inner wall surfaces of the fixing holes.

[0009] Preferably, support columns are fixed at the four corners of the bottom surface of the spray box, and anti-slip pads are fixed at the bottom ends of the support columns.

[0010] Preferably, a fixed folding plate is fixed to the bottom surface of the fixed frame, and a support plate is rotatably arranged inside the fixed folding plate.

[0011] Compared with the prior art, a passivated air ring wind pressure regulating mechanism using the above technical solution has the following beneficial effects:

[0012] 1. The processed metal tube material will pass through the spray box through the sliding hole, and then pass through the sleeve ring after passing through the spray box, which can increase the stability of the metal tube material when moving. After spraying the surface of the metal tube material, the air pump will generate a large amount of flowing gas to blow on the passivation liquid sprayed on the surface of the metal tube material, and evenly apply the passivation liquid on the surface of the metal tube material to form a passivation film. According to the spraying effect of the passivation film on the surface of the metal tube material and the reading of the pressure gauge, the staff will change the air pressure of the air pump. By calibrating the upper and lower limits of the pressure, the staff is prompted to control the air pressure within the specified range, which can increase the effect of spraying the passivation liquid on the surface of the metal tube material and reduce the occurrence of passivation quality problems;

[0013] 2. When the metal tube material continues to slide forward after being sprayed with the passivation liquid, the heater in the working state will inject hot air into the warm box, and the hot air in the warm box will be transported into the fixed frame through the discharge hole, thereby increasing the temperature of the fixed frame. At the same time, part of the hot air will be diverted into the flow pipe, which will surround the surface of the metal tube material, and quickly dry the passivation liquid on the surface of the metal tube material, accelerate the formation of the passivation film, and prevent it from being bumped and scratched;

[0014] 3. In the production process, a large amount of cold water is used to cool down the metal pipe materials. The cooled water may flow everywhere on the floor of the factory. In order to prevent the surface of the spray box from contacting water and rusting, the support column will support the spray box upward away from the ground, and use the support plate to support the fixed frame on the ground to prevent the spray box from tilting due to the offset of the center of gravity.

One end of the output shaft of the driving motor 17 passes through the left rotating hole 18 and is fixed to one end of the left fixing column 20.

[0022] During use, the processed metal tube material will pass through the spray box 1 through the sliding hole 2, and after passing through the spray box 1, it will pass through the sleeve ring 14, which can increase the stability of the metal tube material when moving. After spraying the surface of the metal tube material, the air pump 11 will generate a large amount of flowing gas to blow on the passivation liquid sprayed on the surface of the metal tube material, and evenly apply the passivation liquid on the surface of the metal tube material to form a passivation film. According to the spraying effect of the passivation film on the surface of the metal tube material and the reading of the pressure gauge 13, the staff will change the wind pressure of the air pump 11, and by calibrating the upper and lower limits of the pressure, the staff will be prompted to control the wind pressure within the specified range, which can increase the effect of spraying the passivation liquid on the surface of the metal tube material and reduce the occurrence of passivation quality problems.

At the same time, part of the hot air is diverted into the flow tube 10, which can surround the surface of the metal tube material, and quickly dry the passivation liquid on the surface of the metal tube material, accelerate the formation of the passivation film, and prevent it from being bumped and scratched.
