Description

Technical Field

[0001] The invention relates to the technical field of processing equipment, and in particular to an ultra-thin wall tube processing and forming line. Background Art

[0002] The existing manufacturing process of high-frequency straight seam welded steel pipes mainly includes the following steps: 1. Raw material preparation: Select suitable cold-rolled or hot-rolled steel plates as raw materials; 2. Steel plate forming: Bend the steel plate through a mold to form a steel pipe of a certain shape; 3. Welding: The steel plates at both ends of the steel pipe are heated by high-frequency current to make them melt quickly and tightly join to form a continuous weld. This step is a key link in the manufacturing process of high-frequency welded steel pipes. It is necessary to strictly control parameters such as welding speed, welding pressure and input heat to ensure welding quality; 4. Cooling treatment: After welding is completed, the steel pipe is cooled to achieve the ideal strength and hardness.

[0003] High-frequency welding is a process that uses the resistance heat effect of high-frequency current to weld metal materials together. Its working principle is to place the metal material in the magnetic field of high-frequency current. Under the action of the magnetic field, eddy currents are generated in the metal material, and a large amount of resistance heat is generated, so that the metal material melts and achieves the purpose of welding. This welding method is particularly suitable for welding thin-walled metal materials; however, when welding ultra-thin-walled steel pipes, such as steel pipes with a wall thickness of 0.3-0.43mm, the existing high-frequency straight seam welding steel pipe forming equipment is very prone to welding defects such as wrinkles, pinholes, and pores due to the thin wall thickness of the steel pipe.

The cooling and cleaning assembly 22 includes a cooling cylinder 221, a cooling cavity 222, a conducting pipe 223, a liquid outlet pipe 224, a liquid outlet arc plate 225 and a liquid outlet arc groove 226.

The cooling cylinder 221 is fixed in the distribution mechanism 23 through the other end of the conducting pipe 223. The outer side of the distribution mechanism 23 is provided with an arc opening. The distribution mechanism 23 is provided with an internal cavity inside, which is connected to the conducting pipe 223. The liquid outlet pipe 224 is fixedly connected to the outer surface of the cooling cylinder 221 and is connected to the cooling cavity 222. The liquid outlet arc plate 225 is fixedly connected to the top of the liquid outlet pipe 224, the liquid outlet arc groove 226 is opened at the top of the liquid outlet arc plate 225 and is connected to the liquid outlet pipe 224, the outer surface of the distribution mechanism 23 is fixedly sleeved with a clamping ring, and the clamping rings are symmetrically distributed on both sides of the support seat 24. The liquid outlet assembly 26 includes a liquid outlet ring 261, a liquid guide frame 262 and an adapter arc groove 263. The liquid outlet ring 261 is sleeved on the outer side of the liquid outlet arc plate 225, the liquid guide frame 262 is fixedly connected to the top of the liquid outlet ring 261 and is connected to the adapter arc groove 263 opened at the top of the liquid outlet ring 261, and the top of the liquid guide frame 262 is connected to the liquid outlet at the top of the cooling device 21 A cleaning portion 29 is fixedly provided at the end of the cooling cylinder 221, and the cleaning portion 29 is located on a side close to the fluorescent sensor 28.

The support frame 27 is fixed in the cooling device 21 and is located directly below the fluorescent sensor 28.

[0048] During the cooling process, as the pipeline is transported to the cutting device 5 after welding and the excess waste on the outside of the welding is removed, the pipeline moves into the cooling device 21 after the removal, and the pipeline is inserted into the cooling and cleaning component 22, and the external cooling water mixed with fluorescent night is kept input into the support seat 24, and the rotating mechanism 25 is started. The rotating mechanism 25 drives the cooling and cleaning component 22 to rotate. As the arc mouth on the outside of the distribution mechanism 23 is connected with the through hole in the support seat 24, the coolant is quickly input into the cooling and cleaning component 22 through the distribution mechanism 23, and the coolant fills the cooling cavity 222 and cools the outside of the inserted ultra-thin wall pipeline. At this time, the liquid outlet arc plate 225 on the liquid outlet pipe 224 is connected with the adapter arc groove 263 in the liquid outlet component 26, and the coolant after heat exchange is discharged to the liquid outlet component 26 through the liquid outlet pipe 224 and the liquid outlet arc plate 225, and The liquid is discharged in an upward directional manner.

As the cooling and cleaning component 22 continues to rotate, the adapter arc groove 263 and the arc mouth in the distribution mechanism 23 remain sealed, and the liquid stored in the cooling chamber 222 continues to absorb the heat on the moving ultra-thin-wall pipeline under non-flow. The pipeline portion after cooling is moved to the cleaning part 29 and is frictionally cleaned by the rotating cleaning ring to remove the cooling fluorescent liquid on the pipeline surface. When the pipeline portion infiltrated with fluorescent liquid moves to the support frame 27, the top fluorescent sensor 28 senses the fluorescent liquid remaining on the inner wall of the hole and the inside of the crack, and transmits a defect signal.

[0049] A sealing gasket is provided in the inner wall of the cooling cylinder 221 and is located outside the forming pipeline.

[0051] Firstly, by utilizing the rotating cooling and cleaning component 22 to cooperate with the distribution mechanism 23 and the through hole in the support seat 24 to intermittently connect, intermittent introduction of cooling liquid is achieved, and the rotating cooling and cleaning component 22 is utilized to achieve intermittent connection between the liquid outlet pipe 224 and the liquid outlet component 26, and the cooling and cleaning component 22 that is sleeved with the pipeline dynamic seal is cooperated to fill the limited area with flowing cooling water, and the outside of the pipeline is subjected to a wrapping cooling treatment to avoid liquid splashing caused by spray cleaning, and at the same time, the effect of intermittent connection and output of cooling liquid is achieved, so that the cooling liquid can flow cool and clean the outside of the pipeline on the one hand, and realize continuous heat absorption in a static sealed state on the other hand, thereby improving the cooling and cleaning of the pipeline while further improving the heat absorption time and heat absorption amount of the cooling liquid, reducing the total amount of cooling liquid input, and saving resources.

[0052] In addition, by mixing the fluorescent liquid with the coolant, under the effect of the above-mentioned coolant input filling, the effect of sealing the liquid outlet and continuously supplying liquid at the liquid inlet is coordinated, and the effect of liquid penetrating the defects of the pipeline through holes is improved under the increase of hydraulic pressure, ensuring that when cracks and holes appear in the pipeline, the fluorescent liquid is effectively squeezed into the inner wall of the hole and the inside of the crack, and in conjunction with the subsequent cleaning of the cleaning part 29, the residual fluorescent liquid on the outer side of the pipeline is cleaned, so that the fluorescent liquid infiltrated into the holes and cracks of the pipeline can be detected and discovered by using the fluorescent sensor 28, and the detection and processing of pipeline cracks and holes can be realized while cooling and cleaning.
