[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4The present invention provides a technical solution: a metal processing fixing device with polishing function, comprising a repair pipe 1, the repair pipe 1 including a fixing pipe 11, a filling pipe 18 slidably connected to the end of the fixing pipe 11, a plurality of telescopic shafts 12 provided on the inner walls of both the fixing pipe 11 and the filling pipe 18, the telescopic shafts 12 being sleeved with springs, an outer abrasive block 13 provided at the end of the telescopic shafts 12 on the inner wall of the fixing pipe 11, a rotating shaft 14 provided at the center of the fixing pipe 11, an inner abrasive block 15 sleeved on the rotating shaft 14, and an impact device 2 provided inside the fixing pipe 11. The block 15 is equipped with a collection device 3. Through the outer abrasive block 13 and the inner abrasive block 15, the waste pipe can be fixed inside the fixed pipe 11. The waste pipe is driven to rotate and move forward by the external device. During the movement of the waste pipe, the outer abrasive block 13 and the inner abrasive block 15 can polish the outer and inner walls of the waste pipe. At the same time, the impact device 2 and the collection device 3 can crush and recycle the areas of the waste pipe with insufficient quality, and use the recycled iron powder to fill the damaged parts of the waste pipe, so as to achieve the effect of automatic repair and polishing of the waste pipe. The inner abrasive block 15 includes several inner abrasive blocks 15-1 and several inner abrasive blocks 15-2. Both inner abrasive blocks 15-1 and 15-2 include a linkage sleeve 151. A grinding wheel 152 is provided on the surface of each linkage sleeve 151. A spring is provided between the linkage sleeve 151 and the grinding wheel 152. The inner abrasive blocks 15-1 and 15-2 are separately sleeved on the surface of the rotating shaft 14. The linkage sleeve 151 of inner abrasive block 15-1 is slidably connected to the rotating shaft 14. A planetary gear 153 is provided between the linkage sleeve 151 of inner abrasive block 15-2 and the rotating shaft 14. The abrasive on the sidewall of the grinding wheel 152 is finer, while the abrasive on the outer sides of the front and rear ends of the grinding wheel 152 is coarser. Through the planetary gear 153, the grinding wheels 152 of inner abrasive blocks 15-1 and 15-2 can be rotated in opposite directions. The finer surface is used to grind the inner wall of the old pipe back and forth to improve the polishing effect, and the collection device 3 collects iron powder. When a protrusion appears on the inner wall of the old pipe, the grinding wheel 152 on both sides of the protrusion will have a height difference. The grinding wheel 152 at the lower position will expose the coarser side surface to grind the protrusion and quickly restore the inner wall of the pipe to its original state. Then, the fine surface is polished. This achieves the effect of grinding the inner wall of the pipe after the old pipe is inserted. Real-time detection is carried out during the pipe's advance. For corrosion protrusions in the pipe and protrusions that appear in subsequent repair steps, the coarser surface can be used to grind them flat in time. For intact surfaces or surfaces where protrusions have been ground, the finer surface can be used for polishing. This achieves the effect of real-time detection of the inner wall of the pipe, timely grinding of protrusions, and polishing, maintaining the shape and roughness of the pipe's interior. The telescopic shaft 12 includes an inner shaft 121 and an outer shaft 122. The inner shaft 121 and the outer shaft 122 on the inner wall of the fixed tube 11 are fixedly connected to the outer abrasive block 13 and the fixed tube 11, respectively. The impact device 2 includes a piston groove 21, which is located inside the inner shaft 121. An impact rod 22 is installed inside the piston groove 21. A spring is installed between the impact rod 22 and the inner shaft 121. A rotating tube 16 is sleeved on the fixed tube 11. Several hemispherical blocks 17 are installed inside the rotating tube 16. Hydrogen gas is filled between the fixed tube 11 and the rotating tube 16. The piston groove 21 is located near... A spark plug is installed at one end of the rotating tube 16, and an impact sleeve 23 is installed at the end of the impact rod 22 away from the rotating tube 16. Due to the stationary position of the fixed tube 11 and the continuous rotation of the rotating tube 16, the hemispherical block 17 will continuously push the impact rod 22 to extend, but not fully extend. At this time, in order to drive the outer abrasive block 13 to continuously and slightly impact the outer surface of the waste pipe, the impact will cause the outer abrasive block 13 to vibrate, shaking off the iron powder ground off, cleaning the outer abrasive block 13, ensuring the polishing rate of the outer surface of the waste pipe, and at the same time, it will polish various parts of the waste pipe. The impact test is small and will not damage normal parts, but the over-oxidized parts will be dented. These dents will be smoothed out by the inner abrasive block 15 to facilitate subsequent steps. When oxidation protrusions appear on the surface of the waste pipe, these protrusions will push up the inner shaft 121 via the outer abrasive block 13. Due to the movement of the inner shaft 121, the impact rod 22 will extend to the bottom of the piston groove 21, sealing some hydrogen gas inside. Simultaneously, the spark plug is pressed, causing a small explosion inside the piston groove 21. This causes the impact sleeve 23 to forcefully impact the oxidation protrusions, breaking down the brittle... The weak oxide protrusions facilitate the replacement of the broken parts, achieving the effect of polishing the outer wall of the waste pipe and testing its impact strength. For the external oxide protrusions, the impact force is increased to break them, while the non-protruding oxide parts are dented by a small impact force, and then eliminated with the help of the inner abrasive block 15. This achieves the effects of polishing the outer wall, automatically cleaning the outer abrasive block 13, eliminating the outer wall protrusions, and thinning the non-protruding oxide parts. It is convenient to eliminate the unqualified parts, which facilitates recycling and ensures the overall strength of the waste pipe after subsequent repair. The abrasive wheel 152 has an elastic structure. Positive magnet 24 and negative magnet 25 are respectively installed at the ends of the impact rod 22 on the inner wall of the fixed tube 11 within the abrasive wheel 152. Since metal isolates the magnetic force of the magnets, in the qualified section, due to the thicker pipe, the magnetic isolation is good, and the force between the positive magnet 24 and the negative magnet 25 is small, having no effect on the impact device 2. However, when the impact device 2 and the inner abrasive block 15 work together to thin the non-protruding oxidized part, the magnetic isolation effect of that part is weakened, causing a greater attraction between the positive magnet 24 and the negative magnet 25. This drives the impact rod 22 to move further, allowing an explosion to occur inside the piston groove 21 even in the non-protruding oxidized part. The oxidized parts of this section are broken up. When the qualified part of the inner wall of the waste pipe is dented, the grinding wheel 152, being an elastic structure, will sink into the dented area. At this time, the distance between the positive magnet 24 and the negative magnet 25 decreases, and the force between the positive magnet 24 and the negative magnet 25 increases, causing an explosion inside the piston groove 21. This causes the impact rod 22 to strike the part with great force, knocking the pipe part inward and making the dent on the inner wall not bulge inward. Then, the inner grinding block 15 is used to repair the part and eliminate the bulge. This achieves the effect of breaking up the non-bulging oxidized part and eliminating the dent on the inner wall in conjunction with the inner grinding block 15, thus repairing and maintaining the cylindricity and roughness of the inner wall. The collecting device 3 includes several squeezing rollers 31, which are evenly arranged on the side of the grinding wheel 152 near the rotating shaft 14, near the front and rear ends of the grinding wheel 152. Several squeezing elastic bladders 32 are evenly arranged on the side of the squeezing rollers 31 near the rotating shaft 14. Each squeezing elastic bladder 32 has a hollow structure. The interior of each squeezing elastic bladder 32 is connected to the outer sides of the front and rear ends of the grinding wheel 152 via a reverse one-way valve pipe, and the interior of each squeezing elastic bladder 32 is connected to the interior of the rotating shaft 14 via a positive one-way valve pipe. The number of squeezing elastic bladders 32 is relatively small. During the rotation of the grinding wheel 152, the sand and gravel on both sides will... Rotating in the opposite direction, the compression elastic bladder 32 on one side is squeezed by the compression elastic bladder 32 or the compression roller 31. When the compression elastic bladder 32 bounces up, it draws iron powder from the surface of the grinding wheel 152 through the reverse one-way valve. When squeezed, the iron powder is then transported to the inside of the rotating shaft 14. At the same time, the frictional heat generated by the grinding wheel 152 can quickly react with the air to oxidize the ground iron powder into iron oxide. This can be used for polishing the inner wall of the grinding wheel 152. Since the two sides of the grinding wheel 152 are aligned in this part, and the compression elastic bladders 32 are aligned on both sides of the grinding wheel 152, the polishing process is carried out in a relatively smooth manner. Due to the mutual deformation of the compression elastic bladders 32 and the small number of compression elastic bladders 32, the amplitude and frequency of compression of the compression elastic bladders 32 are small. This can accommodate less iron powder generated during polishing, avoiding vibration of the grinding wheel 152 and preventing uneven polishing of the inner wall of the waste pipe. When a protrusion appears inside, the grinding wheel 152 on the protruding surface is offset, causing a height difference between the two grinding wheels 152. At this time, the compression elastic bladder 32 of the lower grinding wheel 152 will contact the compression roller 31 of the higher grinding wheel 152. Since the compression roller 31 does not deform and the number of compression rollers 31 is small, the compression elastic bladders 32 will be able to withstand the pressure. With a larger quantity, the compression amplitude and frequency of the elastic bladder 32 are greatly increased, which can adapt to the large amount of iron powder generated when grinding the protrusions. This achieves the effect of automatically adjusting the iron powder recovery rate according to the condition of the waste pipe, and the recovered iron powder is quickly oxidized into iron oxide through frictional heat, which is convenient for subsequent use. During polishing, the recovery rate is reduced to accommodate less iron powder and allow the grinding wheel 152 to rotate smoothly. When grinding the protrusions, the recovery rate is increased to recover a large amount of iron powder in time, which ensures the timely recovery of internal iron powder, oxidizes the internal iron powder for convenient subsequent use, and ensures the polishing quality of the inner wall. The inner wall of piston groove 21 is connected to the outer wall pipe of outer shaft 122 via several positive safety valves, and the pipe outlet is inclined towards the fixed pipe 11. A grinding groove 33 is provided at the bottom of fixed pipe 11, and a sliding grinding plate 34 is provided at the bottom of grinding groove 33. A fixed grinding plate 35 is provided on one side of grinding groove 33, and a scraper 36 is provided on one side of fixed grinding plate 35. One end of grinding groove 33 is connected to the internal pipe of rotating shaft 14. The positive safety valves can ensure that sufficient internal pressure is generated inside piston groove 21 after the explosion to ensure the impact force. Then, it is sprayed out from the positive safety valve to the outside. Due to the rotation of the waste pipe itself, the iron powder and fragments on the outside will be thrown to the inner wall of fixed pipe 11. When piston groove 21 explodes, the flame generated will be sprayed out from the positive safety valve, using the high temperature of the explosion to oxidize iron powder and fragments, ensuring that the fragments can be quickly converted into iron oxide. Since the explosive is hydrogen, water is produced during the explosion and sprayed onto the inner wall of the fixed pipe 11. This allows iron powder and fragments to slide off the inner wall of the fixed pipe 11 and fall into the grinding tank 33. The sliding grinding plate 34 moves back and forth due to the pushing and moving of the hemispherical block 17, working with the fixed grinding plate 35 to grind the fragments into iron powder. When the sliding grinding plate 34 resets, the scraper 36 scrapes off the iron powder. When the sliding grinding plate 34 moves again, it pushes the iron powder into the rotating shaft 14. At this time, the water produced by the hydrogen can ensure the fluidity of the iron powder and avoid pipe blockage. This achieves the effect of automatically recycling iron powder and fragments generated outside the old pipe. At the same time, the explosion oxidizes the iron powder and fragments in time, and the fragments are crushed by the sliding grinding plate 34 and the fixed grinding plate 35. The water produced by the explosion also cleans the inner wall of the fixed pipe 11 in time and facilitates the recycling of iron powder. An elastic plate 19 is provided at the end of the telescopic shaft 12 on the inner wall of the filling tube 18. The inner shaft 121 and outer shaft 122 on the inner wall of the filling tube 18 are fixedly connected to the elastic plate 19 and the filling tube 18, respectively. The impact rod 22 on the inner wall of the filling tube 18 is relatively long, and the hemispherical block 17 on the side of the filling tube 18 is relatively large. The bottom center of the piston groove 21 on the inner wall of the filling tube 18 is connected to the aluminum powder box and the interior of the rotating shaft 14 through a reverse one-way valve pipe. The bottom edge of the piston groove 21 on the inner wall of the filling tube 18 is connected to the side of the elastic plate 19 away from the fixed tube 11 through a forward one-way valve pipe. The bottom of the piston groove 21 on the inner wall of pipe 18 is relatively large. Because both the impact rod 22 and the hemispherical block 17 on the inner wall of filling pipe 18 are large, during normal operation, the elastic plate 19 is simultaneously pressed against the outer shell of the waste pipe, causing the impact rod 22 to extend a considerable distance towards the rotating pipe 16. At this time, the angles on both sides of the hemispherical block 17 are too large to press down the impact rod 22. The impact rod 22 is thus stuck by the hemispherical block 17, causing the rotating pipe 16 to drive the filling pipe 18 to rotate, causing the elastic plate 19 to rotate around the waste pipe, detecting the condition of the outer wall of the waste pipe. When dents or defects are found... Due to its own elasticity, the elastic plate 19 moves away from the rotating tube 16, causing the impact rod 22 to move away from the rotating tube 16 as well. At this time, due to the movement of the impact rod 22, the smaller-angled arc surface of the hemispherical block 17 can press down the impact rod 22. Because the hemispherical block 17 is larger at this point, it can completely press down the impact rod 22. During this pressing process, iron oxide powder and aluminum powder in the piston groove 21 will be spilled out. When the impact rod 22 is completely pressed down, it triggers the spark plug, igniting the hydrogen gas and causing an explosion, pushing out all the iron oxide powder and aluminum powder. Simultaneously, due to the bottom of the piston groove 21... The part is relatively large. After the impact sleeve 23 reaches the bottom, the flame can bypass the impact sleeve 23 and spray out from the pipe, igniting the iron oxide powder and aluminum powder, causing an aluminothermic reaction to produce molten iron. Then, the water produced by the hydrogen explosion is quickly cooled to fill the dents or defects. This achieves the effect of automatically detecting the outer wall of the waste pipe and filling the defective parts after removing the unqualified parts. The aluminothermic reaction is carried out by the explosion, which restores the damaged pipe to a complete pipe. This method ensures that after the unqualified parts are removed, the waste pipe can be restored to a complete pipe for reuse. The grinding wheel 152 inside the filling tube 18 has a hollow structure. The inside and outside of the grinding wheel 152 are filled with non-Newtonian fluid, and the inside of the grinding wheel 152 is filled with expanding gas. Normally, due to the low temperature, the pressure of the expanding gas is small, and the non-Newtonian fluid has a large flow rate, which can adhere to the inner wall of the tube in time to ensure the polishing effect. However, when the aluminothermic reaction occurs for filling, the high temperature will heat and expand the expanding gas. The expanding gas will compress the non-Newtonian fluid, and the flow rate of the non-Newtonian fluid will decrease. When it passes the part of the aluminothermic reaction, it will maintain a round shape to avoid deformation of the grinding wheel 152, which would cause the repair position to be concave after water cooling. On the outside of the waste tube, the elastic plate 19 adheres to the tube wall and rotates, which can form a plastic effect on the outside of the molten iron. This achieves the effect of shaping the inside and outside of the tube by the grinding wheel 152 and the elastic plate 19 respectively during tube filling, ensuring that the tube maintains a good cylindricity after the molten iron cools down and can be used directly, thus achieving the effect of automatic repair and shaping of the defective parts. The grinding wheel 152 is made of heat-resistant material. Since the grinding wheel 152 needs to come into contact with molten iron, it needs to have high heat resistance to avoid damage. An air pump is connected to the internal pipe of the rotating shaft 14. A heating device is installed at the air outlet of the air pump. Hot air is blown into the rotating shaft 14 by the air pump and the heating device, which can evaporate the moisture in the iron powder so that the aluminothermic reaction can occur quickly.
