Description

Technical Field

[0001] The invention relates to the technical field of pipe processing, in particular to a process for processing the inner hole of a bright pipe. Background Art

[0002] Bright tube, also known as stainless steel bright tube or mirror tube, is a metal tube with a polished surface that has a high finish and mirror effect. It is usually made of stainless steel materials such as 304 and 316L. They are corrosion-resistant, high-temperature resistant, and have excellent mechanical properties. The surface is finely polished to achieve a very smooth and reflective effect, similar to a mirror. This makes bright tube widely used in decoration, construction, furniture manufacturing, food, pharmaceutical and other industries. In some applications, the smoothness of the inner bore is very important, especially for applications involving fluid or optical transmission. Through grinding and polishing, surface irregularities, minor flaws and impurities can be removed, making the inner bore surface smoother and cleaner, reducing fluid friction resistance and improving optical transmission. The smoothness of the inner bore is crucial for some applications that require reducing friction and obstruction, such as hydraulic and pneumatic systems. Through grinding and polishing, the roughness of the inner bore can be reduced, friction loss can be reduced, and the efficiency and performance of the system can be improved.

[0003] However, there is currently a difficult problem when processing the interior of bright tubes. Due to the narrow space inside the pipe, polishing and grinding work has caused great trouble. It is difficult to effectively grind the inside of the pipe using equipment and tools such as grinders or polishers, which reduces processing efficiency and requires time and cost. Especially in applications requiring high finish and smoothness, more processes and longer processing time are required, resulting in increased production costs. Summary of the Invention

[0004] The purpose of the present invention is to provide a process for treating the inner hole of a bright tube to solve the problems raised in the above background technology.

The bright tube inner hole treatment device includes an operating table 1, a positioning drive mechanism, a floating support mechanism, a connecting mechanism, a circulating injection mechanism, an adsorption mechanism, a cleaning mechanism, and a drying mechanism. The specific method of using the bright tube inner hole treatment device to treat the bright tube inner hole includes the following steps:

[0040] Step 1: Fix the pipe: Raise the floating support mechanism, then place the pipe on the floating mechanism, extend the electric push rod 7 installed on one side of the operating table 1 to drive the positioning drive mechanism to rotate, and then start the drive motor 1 4 on one side of the positioning drive mechanism to drive the positioning drive mechanism to tighten, clamping both ends of the pipe to fix it;

[0041] Step 2: Injecting abrasives: Connect the circulating injection mechanism to the positioning drive mechanism through the connecting mechanism, and then inject the abrasive particles of the circulating injection mechanism into the pipe.

[0042] Step 3: Rotational grinding: The driving unit in the positioning driving mechanism is started to drive the connecting assembly 32, which drives the pipe to rotate. At the same time, the adsorption mechanism located in the operating table 1 is energized to generate magnetic force, which attracts the metal particles in the grinding particles.

Then, the positioning drive mechanism is adjusted to disconnect it from the pipe, and the floating support mechanism is retracted, so that the pipe can roll freely on the top of the operating table 1 toward the cleaning mechanism, and the cleaning mechanism cleans the pipes one by one.

[0044] Step 5: Drying and Collection: The cleaned pipes are taken out and freely rolled into the drying mechanism for one-way heating and drying, and then discharged from the device to complete the processing of the pipes;

At the same time, the rotating rotating frame 1 322 and the rotating frame 2 332 meet the rotation effect of the pipe fittings, start the driving motor 2 326, and drive each timing wheel 324 to rotate through the timing belt 327, so that the pipe fittings rotate with the rotating frame 1 322 and the rotating frame 2 332, which is convenient for comprehensive processing of the inner hole of the pipe fittings.

[0048] Multiple sets of limiting rollers are rotatably provided on one side of the side plate 321. The rollers are located between the timing wheels 324 and squeeze the timing belt 327. Due to the downward pressure of the limiting rollers, the timing belt 327 can fully contact with each timing wheel 324 to maintain the transmission effect.

The top of the guide funnel 52 is connected to a support frame 53, and the top of the support frame 53 is connected to a centrifugal mortar pump 54. The discharge end of the centrifugal mortar pump 54 is connected to a connecting pipe 55, one end of the connecting pipe 55 is communicated with the connecting mechanism, and collecting hoppers 56 are connected on both sides of the inner wall of the material box 51.

One side of the arc-shaped cleaning box 81 is connected to a drain pipe 11. When the reduction motor 85 drives the ferry frame 84 to rotate through the rotating shaft 83, the buckle on the outside of the ferry frame 84 can correspondingly clamp a pipe and take it away, so that the pipe can be separated. At the same time, the rotating shaft 83 is tilted, so that the pipe is slightly tilted to facilitate the discharge of dirt inside the pipe during cleaning.

The wind directions of the two groups of fans 94 are the same, which can ensure the fluidity of the air. When the fan 94 starts to blow air, the heat generated by the heating wire 95 is brought out to dry the inside and outside of the pipe fittings. At the same time, the wind shield 96 effectively limits the air to ensure the drying effect of the flowing hot air on the pipe fittings.
