Description

Technical Field

[0001] This utility model relates to the field of pipe polishing technology, specifically to a pipe blank surface polishing device for stainless steel seamless pipe production. Background Technology

[0002] Stainless steel seamless pipe is a long strip of steel with a hollow cross-section and no seams around its perimeter. It is a type of steel pipe that is resistant to corrosion from weak corrosive media such as air, steam, and water, as well as chemical corrosive media such as acids, alkalis, and salts.

[0003] Before stainless steel seamless tubes leave the factory, their surfaces need to be polished. Existing polishing equipment polishes the stainless steel seamless tubes by having a polishing wheel contact them. However, sparks are generated during polishing. These sparks fall onto the drive roller and, after cooling, adhere to the outer wall of the drive roller, making its surface uneven. This can cause the stainless steel seamless tubes to bounce when rotating on the drive roller, affecting the final polishing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a tube blank surface polishing device for stainless steel seamless tube production, so as to solve the problem mentioned in the background art that after the sparks fall on the drive roller and cool, they adhere to the outer wall of the drive roller, making the surface of the drive roller uneven, which easily causes the stainless steel seamless tube to bounce when rotating on the drive roller, thus affecting the final polishing effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] See also Figure 1-3 This utility model provides a technical solution:

[0021] In this technical solution, a tube blank surface polishing device for stainless steel seamless tube production includes a base plate 1, a first drive roller 3 and a second drive roller 4 are installed on the upper wall of the base plate 1, an outer seamless tube is placed between the first drive roller 3 and the second drive roller 4, a mounting frame 5 is installed on the side wall of the base plate 1, and a polishing mechanism 6 is installed on the side wall of the mounting frame 5. The polishing mechanism 6 can fit against the side wall of the outer seamless tube.

[0022] The first drive roller 3 and the second drive roller 4 have the same structure. The first drive roller 3 includes a drive roller 31, a side plate 32, a first connecting rod 33 and a scraper 34. The drive roller 31 is equipped with side plates 32 at both ends. The side plates 32 are installed on the upper wall of the base plate 1. The drive roller 31 can rotate between the two side plates 32. The first connecting rod 33 is installed between the two side plates 32. There are two first connecting rods 33. The two first connecting rods 33 are located on the front and rear sides of the drive roller 31 respectively. The scraper 34 is installed on the outer side of the first connecting rod 33. The scraper 34 is in contact with the side wall of the drive roller 31.

[0023] In this technical solution, the seamless tube is placed between the first drive roller 3 and the second drive roller 4. Then, the first drive roller 3 is driven to rotate by an external drive motor, so that the seamless tube rotates between the first drive roller 3 and the second drive roller 4. Due to the spirally wound rubber belt 2, the seamless tube can be translated during the rotation and come into contact with the polishing mechanism 6, which then polishes it.

[0024] Because sparks are generated during the polishing process, these sparks are high-temperature debris. Some of these debris will inevitably come into contact with the side walls of the first drive roller 3 and the second drive roller 4, and easily adhere to their exteriors. This will cause the surface of the drive roller 31 to be uneven, which will easily cause the stainless steel seamless tube to bounce when rotating on the drive roller 31, affecting the final polishing effect.

[0025] Therefore, this device is equipped with a first connecting rod 33 and a scraper 34 on both sides of its drive roller 31, so that the surface of the drive roller 31 can be cleaned by the scraper 34 and the attached debris can be scraped off, thereby avoiding the seamless tube from bouncing and affecting the polishing effect.

[0026] In some technical solutions, the polishing mechanism 6 includes a connecting frame 61, a motor 62 and a polishing wheel 63. The connecting frame 61 is installed on the side wall of the mounting frame 5. The motor 62 is inserted into the side wall of the connecting frame 61. The motor 62 is electrically connected to an external power source. The polishing wheel 63 is installed at the output end of the motor 62. The polishing wheel 63 can fit against the side wall of the external seamless tube.

[0027] In this technical solution, the motor 62 can drive the polishing wheel 63 to rotate, so that the polishing wheel 63 polishes the surface of the seamless tube. In this article, the rotation direction of the polishing wheel 63 is opposite to the rotation direction of the seamless tube.

[0028] In some technical solutions, grooves 7 are provided on both the left and right sides of the upper wall of the base plate 1. Slider 8 is slidably installed in both grooves 7. The two sliders 8 are respectively connected to the side plate 32 in the second drive roller 4. Bolts 9 are screwed into the upper wall of the slider 8 and can fit against the inner wall of the groove 7.

[0029] In this technical solution, the position of the second drive roller 4 can be adjusted by the slider 8, so that the position between the first drive roller 3 and the second drive roller 4 can be changed, thereby making the device suitable for polishing seamless tubes of different diameters.

[0030] In some technical solutions, a bracket 10 is installed on the upper wall of the base plate 1. The bracket 10 has an L-shaped cross section. One end of a second connecting rod 11 is installed on the lower wall of the bracket 10. A horizontal plate 12 is installed on the other end of the second connecting rod 11. A driven wheel 13 is installed on the lower wall of the horizontal plate 12. The driven wheel 13 can fit against the upper wall of the external seamless tube.

[0031] In this technical solution, the driven wheel 13 is set to press the seamless tube, which further prevents the seamless tube from bouncing and avoids affecting the polishing effect of the seamless tube.

[0032] In some technical solutions, the second connecting rod 11 includes a main rod body 111, a secondary rod body 112, and a threaded rod 113. The main rod body 111 is installed on the lower wall of the bracket 10. The secondary rod body 112 is inserted into the lower wall of the main rod body 111. The secondary rod body 112 is connected to the upper wall of the horizontal plate 12. The threaded rod 113 is screwed into the side wall of the main rod body 111. The threaded rod 113 can fit against the side wall of the secondary rod body 112.

[0033] In this technical solution, the second connecting rod 11 is a telescopic rod, and its length can be adjusted by adjusting the auxiliary rod body 112 so that the driven wheel 13 can fit against the upper wall of the seamless tube.

[0034] In some technical solutions, rubber belts 2 are wound and installed on the outer sides of both the first drive roller 3 and the second drive roller 4.

[0035] In this technical solution, the rubber belt 3 is spirally wound around the outside of the drive roller 31. On the one hand, it can increase the friction between the seamless tube and the drive roller 31, and on the other hand, it can make the seamless tube move between the first drive roller 3 and the second drive roller 4 while rotating.

[0036] Working principle: The seamless tube is placed between the first drive roller 3 and the second drive roller 4. Then, the first drive roller 3 is driven to rotate by an external drive motor, so that the seamless tube rotates between the first drive roller 3 and the second drive roller 4. Due to the spirally wound rubber belt 2, the seamless tube can be translated during the rotation and come into contact with the polishing mechanism 6. The polishing mechanism 6 then polishes the tube.

[0037] Sparks are generated during the polishing process. These sparks are high-temperature debris. Some of the debris will inevitably come into contact with the side walls of the first drive roller 3 and the second drive roller 4, and easily adhere to their exterior. This will cause the surface of the drive roller 31 to be uneven, which will easily cause the stainless steel seamless tube to bounce when rotating on the drive roller 31, affecting the final polishing effect.

[0038] Therefore, this device is equipped with a first connecting rod 33 and a scraper 34 on both sides of its drive roller 31, so that the surface of the drive roller 31 can be cleaned by the scraper 34 and the attached debris can be scraped off, thereby avoiding the seamless tube from bouncing and affecting the polishing effect.
