[0002] Stainless steel pipe making machines, also known as pipe welding machines, are mechanical equipment specifically designed for the production of stainless steel pipes. They are mainly divided into high-frequency pipe making machines and stainless steel pipe making machines, the latter also known as stainless steel welded pipe machines. Due to their unique corrosion resistance, high temperature resistance, and high strength, stainless steel pipes are widely used in construction, automotive, aerospace, medical and other fields. The emergence of stainless steel pipe making machines has greatly promoted the production efficiency and product quality of stainless steel pipes, meeting the market demand for high-quality stainless steel pipes.

[0003] During the operation of current stainless steel pipe making machines, the weld seam of the stainless steel pipe is subjected to lateral pressure from the rollers. Under the extrusion force, excess metal and oxides accumulate on the upper part of the weld seam, thus forming burrs on the outer surface and reducing the surface quality of the stainless steel pipe. To address this, we propose a stainless steel pipe making machine with a deburring mechanism. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel pipe making machine with a deburring mechanism, which has the advantage of easily grinding and removing surface burrs at the weld seam of the formed stainless steel pipe, thereby improving the surface quality of the stainless steel pipe. It solves the problem that in the current stainless steel pipe making machine, during operation, excess metal and oxides accumulate on the upper part of the weld seam due to the lateral pressure of the roller during welding, thus forming burrs on the outer surface and reducing the surface quality of the stainless steel pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel tube deburring machine with a deburring mechanism, comprising a grinding motor, a conveying motor, a U-shaped frame, a conveying roller, and a grinding roller. The grinding roller and a support roller are rotatably installed inside the U-shaped frame, with the grinding roller positioned above the support roller. Conveying rollers are rotatably installed inside the U-shaped frame near the grinding roller and the support roller. Limiting guide rollers are rotatably installed on both sides of the U-shaped frame near the front and rear surfaces. Annular grooves are provided on the outer surfaces of the limiting guide roller, the conveying roller, the grinding roller, and the support roller.

[0006] Preferably, a grinding motor is fixedly installed on the front surface of the U-shaped frame near the grinding roller, and the end of the output shaft of the grinding motor is fixedly connected to one end of the grinding roller near the front surface of the U-shaped frame.

[0007] Preferably, a transmission motor is fixedly installed on the front surface of the U-shaped frame near the position of the transmission roller. The end of the output shaft of the transmission motor is fixedly connected to one end of the transmission roller near the front surface of the U-shaped frame. A transmission gear is fixedly connected to one end of each of the two transmission rollers near the rear surface of the U-shaped frame, and the two transmission gears mesh with each other.

[0008] Preferably, a gear protective cover is fixedly installed on the rear surface of the U-shaped frame, and both of the transmission gears are located inside the gear protective cover.

[0009] Preferably, fixing plates are fixedly installed on both sides of the upper surface of the U-shaped frame.

[0010] Preferably, a base is fixedly installed on the lower surface of the U-shaped frame, and fixing holes are provided on the upper surface of the base near the four corners.

[0011] Preferably, a dust collection hood is fixedly installed inside the U-shaped frame at a position below the support roller, and a dust collection pipe is fixedly connected to the outer surface of the dust collection hood.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a U-shaped frame, conveying rollers, limiting guide rollers, grinding rollers, support rollers, annular grooves, a grinding motor, and a conveying motor, achieves the effect of facilitating the removal of surface burrs at the weld seam of the formed stainless steel pipe, thereby improving the surface quality of the stainless steel pipe. The welded stainless steel pipe passes through the inside of the U-shaped frame and is conveyed by two conveying rollers. The limiting guide rollers play a limiting and guiding role in the conveying of the stainless steel pipe. During the process of the stainless steel pipe passing through the inside of the U-shaped frame, the grinding rollers rotate to grind away the surface burrs at the weld seam. The annular groove can increase the contact area between the limiting guide rollers, conveying rollers, and support rollers and the stainless steel pipe, which is beneficial to the conveying of the stainless steel pipe by the conveying rollers. It also plays a limiting role in the stainless steel pipe and increases the grinding contact area between the grinding rollers and the stainless steel pipe, avoiding grinding dead corners at the weld seam.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model proposes a stainless steel tube deburring machine, including a grinding motor 1, a conveying motor 2, a U-shaped frame 5, a conveying roller 9, and a grinding roller 10. The grinding roller 10 and a support roller 14 are rotatably mounted inside the U-shaped frame 5, with the grinding roller 10 positioned above the support roller 14. The grinding motor 1 is fixedly mounted on the front surface of the U-shaped frame 5 near the grinding roller 10. The end of the output shaft of the grinding motor 1 is fixedly connected to one end of the grinding roller 10 near the front surface of the U-shaped frame 5. The grinding motor 1 drives the grinding roller 10 to rotate. Inside the frame 5, near the positions of the grinding roller 10 and the support roller 14, a conveyor roller 9 is rotatably mounted. A conveyor motor 2 is fixedly mounted on the front surface of the U-shaped frame 5 near the position of the conveyor roller 9. The end of the output shaft of the conveyor motor 2 is fixedly connected to one end of one of the conveyor rollers 9 near the front surface of the U-shaped frame 5. A transmission gear 15 is fixedly connected to one end of each of the two conveyor rollers 9 near the rear surface of the U-shaped frame 5, and the two transmission gears 15 mesh with each other. The conveyor motor 2 drives one of the conveyor rollers 9 to rotate, and the two conveyor rollers 9 are driven by the transmission gear 15 through meshing.

[0023] A gear protective cover 8 is fixedly installed on the rear surface of the U-shaped frame 5, and both transmission gears 15 are located inside the gear protective cover 8. The gear protective cover 8 plays a role in sealing and protecting the transmission gears 15, preventing dust and impurities from adhering to the surface of the transmission gears 15 and causing gear wear, and also preventing accidental contact with the transmission gears 15 and causing mechanical damage. Limiting guide rollers 6 are rotatably installed on both sides of the U-shaped frame 5 near the front and rear surfaces. The outer surfaces of the limiting guide rollers 6, the conveying rollers 9, the grinding rollers 10, and the support rollers 14 are all provided with annular grooves 7.

Bolts pass through the fixing holes 3 to fix the base 4.

[0024] In use, the welded stainless steel tube passes through the U-shaped frame 5 and is conveyed by two conveying rollers 9. The limiting guide roller 6 plays a limiting and guiding role for the conveyed stainless steel tube. During the process of the stainless steel tube passing through the U-shaped frame 5, the grinding roller 10 rotates to grind away the surface burrs at the weld. The annular groove 7 can increase the contact area between the limiting guide roller 6, the conveying roller 9, and the support roller 14 and the stainless steel tube, which is beneficial to the conveying of the stainless steel tube by the conveying roller 9. At the same time, it also plays a limiting role for the stainless steel tube and increases the grinding contact area between the grinding roller 10 and the stainless steel tube, avoiding grinding dead corners at the weld.
