[0002] Metal pipes are widely used in machinery manufacturing, construction, transportation and other fields. Their surface quality directly affects the performance and appearance of the pipes.

[0003] The existing metal strip forming and surface treatment processes usually have the following problems: during the initial processing of metal strip, oxide layers, burrs and pits are easily formed on the surface. If these surface defects are not effectively removed, they will lead to poor surface quality of the pipe during subsequent pipe forming and welding processes, and may even affect the strength of the welded joint.

[0004] Traditional surface treatment equipment is mostly unidirectional or localized polishing, which cannot treat the pipe surface in a comprehensive, continuous and uniform manner. The polishing effect is uneven and the processing efficiency is low. In the process of conveying and guiding the tape, there is a lack of effective tensioning and guiding devices, which can easily lead to tape skewing, folding or damage, resulting in an increase in surface defects of the formed pipe.

[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

Detailed Implementation

[0021] like Figures 1 to 3 As shown, a wire drawing, tube forming, and polishing equipment includes a tube forming machine unit 10, a 360-degree wire drawing and polishing device 20, and a metal strip surface polishing device 30. The metal strip surface polishing device 30 is located at the left end of the tube forming machine unit 10, and the 360-degree wire drawing and polishing device 20 is located at the right end. In operation, the metal strip first undergoes preliminary surface treatment through the metal strip surface polishing device 30. Multiple sets of sequentially arranged polishing rollers polish the strip surface step by step to remove the oxide layer, burrs, and pits, ensuring a smooth and clean surface for subsequent forming. After preliminary polishing, the strip enters the tube forming machine unit 10, which contains several sequentially arranged forming molds. The dimensions of each mold gradually decrease, and the strip passes through sequentially, gradually bending and closing for welding, thereby forming a round or square tube of the required specifications. After the forming is completed, the pipe directly enters the 360-degree wire drawing and polishing device 20. The wire drawing and polishing device includes a ring-shaped polishing component. Each polishing component is fixed by a ring-shaped bracket and driven by a drive motor to rotate the polishing wheel at high speed. The pipe passes through the ring polishing area under the drive of the conveying roller, thereby realizing the all-round wire drawing and polishing treatment of the outer surface of the pipe.

[0022] In practical implementation, the metal strip surface polishing equipment 30 includes an equipment mounting frame 31. A plurality of motor brackets 32 are sequentially mounted on one side of the equipment mounting frame 31. Drive motors 33 are respectively mounted at the lower ends of the plurality of motor brackets 32, and roller mounting portions 34 are respectively mounted at the upper ends of the plurality of motor brackets 32. A movable roller 341 is movably connected to the middle of the roller mounting portion 34. One end of the drive motor 33 is provided with a first belt connecting portion 331, and one end of the movable roller 341 is provided with a second belt connecting portion 342. A transmission belt 35 connects the first belt connecting portion 331 and the second belt connecting portion 342. The other end of the roller 341 is connected to a polishing roller 343. The inside of the mounting frame 31 of the equipment is recessed with a roller mounting groove 311. The polishing roller 343 is set in the roller mounting groove 311. When in use, after the drive motor 33 is powered on, it drives the transmission belt 35 through the first belt connection part 331, which in turn drives the second belt connection part 342 to rotate, so that the movable roller 341 rotates synchronously, thereby driving the polishing roller 343 at the other end to rotate at high speed. When the metal strip passes between the polishing roller 343 and the opposing roller, its surface will be subjected to continuous friction and grinding, thereby achieving the effect of removing oxide layer, burrs and pits.

[0023] In practical implementation, the upper end of the mounting frame 31 of the equipment is provided with a transmission slot 36. Several single-drive rollers 361 and several double-drive rollers 362 are evenly and rotatably mounted inside the transmission slot 36. These single-drive rollers 361 and double-drive rollers 362 are arranged alternately and sequentially. The single-drive rollers 361 and double-drive rollers 362 are correspondingly positioned above the polishing roller 343. One end of the transmission slot 36 is provided with a winding inlet 363. The other end of the transmission slot 36 is provided with a winding exit opening 364. In use, the metal strip is fed in through the winding entry opening 363. Under the sequential guidance of the single transmission roller 361 and the double transmission roller 362, it runs smoothly along the direction of the transmission slot 36 and comes into close contact with the polishing roller 343 below to achieve continuous polishing. After the strip passes through multiple sets of polishing rollers 343 to remove the oxide layer, burrs and pits step by step, it is output from the winding exit opening 364 and enters the subsequent tube forming unit for forming processing.

[0024] In practical implementation, one end of the transmission slot 36 is provided with a winding mounting part 37, and a winding transmission component 371 is mounted on the surface of the winding mounting part 37. The winding transmission component 371 is located at the front end of the unwinding opening 363. A winding roller 372 is rotatably connected between the winding transmission components 371. The other end of the transmission slot 36 is provided with an unwinding mounting part 38, and an unwinding transmission component 381 is mounted on the surface of the unwinding mounting part 38. The unwinding transmission component 381 is located at the front end of the unwinding opening 364. An unwinding roller 382 is rotatably connected between the unwinding transmission components 381. In use, the metal strip is first clamped and guided into the area of ​​the transmission slot 36 by the winding roller 372. Under its rolling action, the winding roller 372 can stably control the feeding direction and feeding speed of the strip, preventing the strip from deviating or folding. After the belt roll passes through the single-drive roller 361, the double-drive roller 362, and the polishing roller 343 below within the drive slot 36 and undergoes surface polishing treatment in stages, it is clamped and guided by the unwinding roller 382 at the unwinding end and output. The unwinding roller 382 not only provides stable guidance during the unwinding process but also provides appropriate tension to the belt roll, preventing a decrease in polishing quality due to slack during high-speed operation.

[0025] In practical implementation, the outer sides of the first belt connecting part 331 and the second belt connecting part 342 are fitted with belt housings 39. In use, the belt housings 39 can form a closed protection for the transmission belt 35, preventing the transmission belt 35 from being worn or falling off due to the entry of external debris during high-speed operation. At the same time, it can also prevent operators from accidentally contacting the high-speed running belt components when approaching the equipment, thereby improving the safety of the equipment.

[0026] In summary, the metal strip surface polishing equipment 30 is located at the left end of the tube forming machine unit 10, and the 360-degree wire drawing and polishing device 20 is located at the right end of the tube forming machine unit 10. A plurality of motor brackets 32 are sequentially installed on one side of the equipment mounting frame 31. Drive motors 33 are respectively installed at the lower ends of the plurality of motor brackets 32, and roller mounting portions 34 are respectively installed at the upper ends of the plurality of motor brackets 32. A movable roller 341 is movably connected to the middle of the roller mounting portion 34. One end of the drive motor 33 is provided with a first belt connecting portion 331, and one end of the movable roller 341 is provided with a second belt connecting portion 342. A transmission belt 35 connects the first belt connecting portion 331 and the second belt connecting portion 342. The other end of the movable roller 341 is connected to... The device is equipped with a polishing roller 343. The upper end of the mounting frame 31 of the equipment is provided with a transmission slot 36. Several single-drive rollers 361 and several double-drive rollers 362 are evenly installed inside the transmission slot 36. The single-drive rollers 361 and several double-drive rollers 362 are correspondingly arranged above the polishing roller 343.
