Description

Technical Field

[0001] The utility model relates to the technical field of metal bent pipes, in particular to a surface treatment device for metal bent pipes. Background Technique

[0002] Metal bent pipes are bent by using a complete set of bending equipment, which are divided into two processes: cold bending and hot pushing. They are mainly used for oil transportation, gas transportation, and liquid transportation. Due to factors such as terrain, equipment layout, and transportation path, it is necessary to cooperate with metal straight pipes through metal bent pipes to form corresponding pipeline lines.

[0003] For the surface grinding and cleaning of metal bent pipes, a conveying device is often used to slowly convey the metal bent pipes. During the conveying process, the metal bent pipes pass through the grinding device and are subjected to circumferential grinding treatment. During this process, the stability of the metal bent pipes themselves and the grinding performance of the grinding device will affect the grinding and cleaning effects of the metal bent pipes. Due to the special shape of the metal bent pipes, even a small horizontal or vertical offset of the metal bent pipes will cause the docking offset between the metal bent pipes and the grinding device and the cleaning device, affecting the circumferential grinding and cleaning operations.

[0004] The fixing devices used for the surface treatment of bent pipes at the present stage have a simple structure and an unsatisfactory fixing effect. Displacement is likely to occur during surface treatment, so that the surface treatment of metal bent pipes cannot be carried out. At the same time, due to unstable fixing inside the treatment device, the metal bent pipes are prone to being unable to carry out normal surface treatment work, and at the same time, the metal bent pipes are damaged, thereby increasing the production cost of the metal bent pipes, reducing the working efficiency of the surface treatment device, and having a poor surface treatment effect, affecting the yield rate of the finished bent pipes. There is a need for a surface treatment device for metal bent pipes to solve the above technical problems. Content of the Utility Model

[0026] Specifically, the upper support base 2 is fixed to the support base 1 through a hinge, and the upper support base 2 is closed and installed on the top surface of the support base 1. The support base 1 and the upper support base 2 are symmetrically installed, and the control panel 4 is fixedly connected to the side surface of the upper support base 2. The advantage is that the upper support base 2 is lifted from the top surface of the support base 1 and stationary on the top surface of the positioning seat 6 according to the placement position of the electric slide rail 9. Then, the upper support base 2 is closed on the top surface of the support base 1, and the positioning seats at both ends of the inner walls of the support base 1 and the upper support base 2 respectively clamp and position the two ends of the metal steel pipe. And the metal steel pipe is placed statically inside the support base 1. The electric slide rail 9 is started by using the control panel 4 to drive the electric slider 10 to slide in a curve inside the electric slide rail 9. While the U-shaped frame 11 is fixedly connected between the electric sliders 10, the arc-shaped grinding roller 12 in the middle of the U-shaped frame 11 grinds the outer wall of the metal steel pipe to clean the impurities on its outer wall.

[0027] Specifically, the arc-shaped grooves 3 are respectively formed at both ends of the upper support base 2, and lower arc-shaped grooves are correspondingly formed at both ends of the support base 1 opposite to the arc-shaped grooves 3. The material receiving plate 8 is inserted into the inner side of the limit groove 5. A metal bent pipe is arranged between the arc-shaped grooves 3 and is detachably installed. The advantage is that the angle between the electric slide rails 9 corresponds to that between the metal steel pipes, so that the electric slider 10 slides along between the electric slide rails 9, and the arc-shaped grinding rollers 12 slide correspondingly along the outer side of the metal steel pipe, capable of grinding the impurities on the outer wall of the metal steel pipe clean.

[0028] Specifically, the inner walls of both ends of the support base 1 and the upper support base 2 are respectively fixedly connected with the aggregate frames 7, and semi-circular grooves are formed inside the aggregate frames 7.

Upper arc-shaped grinding rollers are symmetrically installed on the top surface of the arc-shaped grinding roller 12. The advantage is that when the arc-shaped grinding roller 12 processes the outer wall of the metal bent pipe, the aggregate frame 7 can directly receive the impurities ground by the arc-shaped grinding roller 12 and concentrate them at the middle position of the aggregate frame 7, and directly drop them into the inner side of the material receiving plate 8 through the discharge groove at its bottom for centralized collection. After completion, it is extracted from the bottom of the support base 1 for cleaning, avoiding the accumulation of impurities inside the support base 1 and the upper support base 2 from affecting the normal operation of the fittings.

[0030] During use, the upper support base 2 is lifted from the top surface of the support base 1 and placed statically on the top surface of the positioning base 6 according to the placement position of the electric slide rail 9. Subsequently, the upper support base 2 is closed on the top surface of the support base 1, and the positioning bases at both ends of the inner walls of the support base 1 and the upper support base 2 respectively clamp and position both ends of the metal steel pipe. The metal steel pipe is placed statically inside the support base 1. The electric slide rail 9 is started by using the control panel 4 to drive the electric slider 10 to slide in a curved path inside the electric slide rail 9. While the U-shaped frame 11 is fixedly connected between the electric sliders 10, the arc-shaped grinding roller 12 in the middle of the U-shaped frame 11 grinds the outer wall of the metal steel pipe to clean the impurities on its outer wall. The angle between the electric slide rails 9 corresponds to that between the metal steel pipes, so that the electric slider 10 slides along the electric slide rails 9, and the arc-shaped grinding rollers 12 slide corresponding to the outer side of the metal steel pipe, enabling the impurities on the outer wall of the metal steel pipe to be ground clean. The metal steel pipe is ground under the condition of static limiting to avoid deviation, which affects the normal sliding of the electric slide rail 9 driving the arc-shaped grinding roller 12, thereby ensuring the stability of the inner fittings of the support base 1 and the upper support base 2, and further ensuring the normal operation of the inner fittings.
