Description

Technical Field

[0001] This utility model relates to the field of PE water supply pipe processing technology, and in particular to a polishing device for processing the cut of steel wire mesh skeleton PE water supply pipe. Background Technology

[0002] Steel wire mesh reinforced PE composite pipe, as a new type of pipe material, combines the strength of steel with the corrosion resistance of polyethylene, and is widely used in water supply, gas transmission, and other fields. During pipeline installation, the pipe needs to be cut according to actual laying requirements, and the quality of the cut directly affects the connection sealing performance and service life of the pipe. Due to the special structure of this type of pipe, the cut surface easily exposes the internal steel wire skeleton, and burrs and uneven surfaces are easily formed on the inner and outer walls of the pipe end during the cutting process. Furthermore, the outer wall of the cut end usually needs to be polished to remove the oxide layer. Improper handling can easily lead to stress concentration, corrosion, and leakage.

[0003] Currently, the cutting and finishing of ordinary PE pipes mostly employs manual grinding or simple mechanical polishing methods, which suffer from low efficiency and poor polishing uniformity. Existing pipe end processing equipment, while achieving a certain degree of automation, has relatively limited functionality, typically only processing the outer wall or end face. Therefore, we propose a polishing device for processing the cut ends of steel wire mesh reinforced PE water supply pipes. Utility Model Content

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.

[0018] like Figure 1-6 As shown, a polishing device for processing the cut of a steel wire mesh reinforced PE water supply pipe 2 includes a processing table 1. A first mounting plate 3 is fixedly installed at one end of the upper surface of the processing table 1. A first servo motor 4 is fixedly installed at the upper end of the first mounting plate 3. A fixed disk 9 is fixedly installed at the output end of the first servo motor 4. A tensioning component is provided at the center of the outer wall of the fixed disk 9. A support frame 5 is also fixedly installed on the upper surface of the processing table 1. The water supply pipe 2 is placed on the upper surface of the support frame 5. One end of the water supply pipe 2 is fixed by the tensioning component. A mounting base 7 is fixedly installed on the upper surface of the processing table 1 below the tensioning component. A polishing wheel 6 is rotatably installed on the upper end of the mounting base 7. A second servo motor 8 is fixedly installed on the outer wall of the upper end of the mounting base 7. The output end of the second servo motor 8 is fixedly connected to the center of the outer wall of the end of the polishing wheel 6. The polishing wheel 6, located below the water supply pipe 2, rotates at high speed under the drive of the second servo motor 8, which can polish the oxide layer on the outer wall of the end of the water supply pipe 2 at the same time.

[0019] like Figure 5 As shown, a second mounting plate 20 is fixedly mounted on the upper outer wall of the mounting base 7 on the side away from the second servo motor 8. An extension shaft 22 is fixedly mounted at the center of the outer wall of the polishing wheel 6. The extension shaft 22 extends through the upper end of the mounting base 7 and the corresponding position on the second mounting plate 20 to the outside of the second mounting plate 20. A first gear 16 is fixedly mounted at the end of the extension shaft 22 located on the outside of the second mounting plate 20. A second gear 17 is rotatably mounted on the upper end of the second mounting plate 20. The first gear 16 and the second gear 17 are meshed and connected. A polishing wheel is fixedly mounted at the center of the outer wall of the second gear 17. The grinding disc 21 contacts the outer wall of the end of the water supply pipe 2. Under the connection of the extension shaft 22, the polishing wheel 6 rotates synchronously with the first gear 16. Then, under the meshing action between the first gear 16 and the second gear 17, the second gear 17 is driven to rotate. A circular column is provided between the second gear 17 and the grinding disc 21. The circular column is rotatably installed on the upper end of the second mounting plate 20. When the second gear 17 rotates, it drives the grinding disc 21 to rotate synchronously. The end face of the cut can be ground and polished by the contact between the grinding disc 21 and the end section of the PE water supply pipe 2.

[0020] like Figure 5 As shown, an extension rod 18 is fixedly installed on the upper outer wall of the second mounting plate 20, and a grinding block 19 is detachably installed at the end of the extension rod 18; the grinding block 19 can be used to chamfer and grind the inner edge of the end of the water supply pipe 2.

[0021] As shown in Figure 3, the tensioning assembly includes a fixed block 15 fixedly installed at the end of the rotating shaft 10. A sliding block 12 is also slidably installed on the outer wall of the rotating shaft 10. Multiple opening rods 13 are rotatably installed on both the sliding block 12 and the fixed block 15. The ends of two opening rods 13 corresponding to the sliding block 12 and the fixed block 15 are movably connected to a stop rod 14. The multiple sets of opening rods 13 simultaneously open the multiple stop rods 14 outward, thereby squeezing the inner wall of the water supply pipe 2 outward through the multiple stop rods 14. Rubber pads or the like can be added to the outer wall of the stop rod 14 to increase the friction between the outer wall of the stop rod 14 and the inner wall of the water supply pipe 2.

[0022] like Figure 3 As shown, multiple electric telescopic rods 11 are provided between the fixed disk 9 and the sliding block 12. The two ends of the electric telescopic rods 11 are fixedly connected to the corresponding positions on the outer walls of the fixed disk 9 and the sliding block 12, respectively. The electric telescopic rods 11 are extended and shortened by the controller, making the device more automated and intelligent in use.

[0023] like Figure 6 As shown, the grinding block 19 is inclined and contacts the inner end of the water supply pipe 2. The inclination angle of the grinding block 19 is between 15 and 30 degrees. The grinding block 19 contacts the end of the water supply pipe 2. During the rotation of the water supply pipe 2, the inner wall edge of the water supply pipe 2 can be ground and polished by the grinding block 19.

[0024] like Figure 6 As shown, the grinding block 19 has a threaded hole at its end, and the extension rod 18 has a bolt movably installed at its end. The grinding block 19 is fixed by the engagement of the bolt with the threaded hole on the grinding block 19. The grinding block 19 can be removed from the extension rod 18 by removing the bolt. When the grinding block 19 is worn after long-term use, it can be removed and replaced.

[0025] The working principle of this utility model is as follows: In use, the cut steel wire mesh skeleton PE water supply pipe 2 is placed on the upper end of the support frame 5. The support frame 5 supports the PE pipe. The tensioning component on the upper end of the first mounting plate 3 tensions and fixes one end of the water supply pipe 2. When the electric telescopic rod 11 is energized, it extends under the action of the controller (CPM1A PLC controller). This allows the electric telescopic rod 11 to push the sliding block 12 forward, shortening the distance between the sliding block 12 and the fixed block 15. Then, the two opening rods 13 cause the abutment rod 14 to open outwards. The coordinated opening of multiple abutment rods 14 tensions the inner wall of the water supply pipe 2. Subsequently, the first servo motor 4 drives the fixed plate 9 to rotate, which in turn drives the water supply pipe 2 to rotate. The polishing wheel 6, located below the water supply pipe 2, rotates at high speed under the drive of the second servo motor 8, simultaneously polishing the oxide layer on the outer wall of the end of the water supply pipe 2. When the polishing wheel 6 rotates, the extension shaft 22 drives the first gear 16 to rotate. When the first gear 16 and the second gear 17 are engaged, the grinding disc 21 rotates under the transmission action of the first gear 16 and the second gear 17. The grinding disc 21 can grind and polish the end face of the cut of the water supply pipe 2. At the same time, the grinding block 19 located on the upper end of the second mounting plate 20 contacts the edge of the inner circle of the end of the water supply pipe 2. During the rotation of the water supply pipe 2, the grinding block 19 can grind the inner wall edge of the water supply pipe 2. Thus, the cut polishing device can simultaneously grind and polish the oxide layer on the outer wall of the cut of the steel wire mesh skeleton PE water supply pipe 2 as well as the edge of the cut end and the inner circle end.
