Description

Technical Field

[0001] The present invention relates to the field of metal water pipe processing equipment, and specifically to an automated production and processing equipment for bathroom metal water pipes. Background Art

[0002] As a core component of the bathroom system, the production quality and efficiency of bathroom metal water pipes directly affect the overall performance and production cost of bathroom products. With the large-scale development of the bathroom industry and the increasing requirements of consumers for product precision, the traditional manual or semi-automated processing mode has exposed significant drawbacks.

[0003] In traditional processes, operations such as grinding and cutting of metal water pipes mostly rely on manual operation or independent single-machine equipment. It is necessary to frequently stop the machine to transfer workpieces, and continuous production cannot be achieved, making it difficult to meet the needs of large batch orders. Manual grinding is prone to uneven surface roughness of the weld due to operation errors. When cutting, if the pipe is not firmly fixed or the tool is worn, problems such as burrs on the cut and dimensional deviations will occur, affecting the subsequent assembly accuracy and product sealing performance. The multi-process split operation requires a large amount of labor and has high requirements for the skill level of operators. With the increase in labor costs, the economy of the traditional mode is gradually declining.

[0004] The current technical bottlenecks of bathroom metal water pipe production equipment are mainly concentrated in the following aspects. Firstly, most traditional grinding equipment uses grinding discs with fixed angles, which are difficult to fit the complex curved surfaces of water pipe welds (such as elbows and tee joints), and it is easy to have grinding blind spots or excessive grinding resulting in a reduction in the wall thickness of the pipe. Some equipment uses sandpaper or polishing wheels for static polishing, which can only handle macroscopic scratches on the surface and cannot eliminate microscopic defects, making it difficult to meet the mirror polishing requirements of high-end bathroom products. Grinding and polishing need to be completed on different equipment, and secondary pollution or bump damage is likely to occur during the workpiece transfer process, affecting the quality of the finished product.

[0005] Secondly, traditional cutting equipment needs to wait for the pipe to be completely stationary before cutting, and the feeding and cutting processes cannot be synchronized. Especially for long-specification pipes, frequent starts and stops lead to a break in the production rhythm. During static cutting, the contact area between the tool and the pipe is large, the resistance is high, and it is easy to generate cutting heat resulting in pipe deformation. At the same time, the tool wears quickly and needs to be frequently replaced, increasing the maintenance cost. After cutting, manual secondary processing such as deburring and chamfering of the cut is required, increasing the complexity of the process and the manual intervention link. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present invention provides an automated production and processing equipment for bathroom metal water pipes, which solves the problems of low efficiency, poor precision, and high dependence on manual labor in traditional processes, meets the needs of the bathroom industry for high-quality and large-scale production of metal water pipes, and has significant industrial application value.

The inner side ends of the driving bevel gear and the driven bevel gear are meshed and connected.

[0009] Preferably, a second motor is fixedly installed on the front side of the back plate near one side of the first rotating shaft, and the driving end of the second motor is fixedly installed at one end of the first rotating shaft. A first worm is fixedly installed at the end of the first rotating shaft. A movable shaft is movably installed on the front side of the back plate near the lower side position of the first worm. A first worm gear is fixedly installed on the outer diameter of the middle part of the movable shaft, and the inner side end of the first worm gear is meshed and connected with the inner side end of the first worm.

[0010] Preferably, an upper guide wheel is fixedly installed at the front end of the movable shaft. A lower guide wheel is fixedly installed at the position below the upper guide wheel on the top end of the processing table. A material placing table is fixedly installed at the position below the movable table on the top end of the processing table.

[0011] Preferably, a grinding box is fixedly installed on one side of the top end of the processing table through a bracket. A second rotating shaft is movably installed on the upper side inside the grinding box. A cylinder body is fixedly installed on the outer diameter of one side of the second rotating shaft. An inclined ball groove is formed on the outer diameter of the cylinder body, and an inclined bearing seat is movably installed in the ball groove. A swing rod is fixedly installed at the bottom end of the inclined bearing seat. A sliding seat is movably installed on the lower side inside the grinding box through two guide rods. The bottom end of the swing rod is movably installed on the top end of the sliding seat. A grinding disc is installed at the bottom end of the sliding seat through four spring rods.

[0012] Preferably, a hollow ring is fixedly installed on one side inside the grinding box. The hollow ring is filled with polishing magnetic needles. An opening is formed at the bottom end of the hollow ring. A short shaft is movably installed on one side of the inner wall of the grinding box close to the hollow ring.

[0014] The present invention provides an automated production and processing device for bathroom metal water pipes. It has the following beneficial effects:

[0015] 1. In the present invention, the bidirectional spiral groove of the first rotating shaft drives the movable table to reciprocate through the round head pin, so that the cutting circular saw remains relatively stationary with the moving metal water pipe, and cutting can be completed during the continuous transmission of the water pipe, avoiding the efficiency loss caused by traditional stop cutting, and significantly improving the production rhythm.

[0016] 2. In the present invention, the upper sliding table and the lower sliding table are connected by a return spring. When the electric cylinder drives the cutting, the transmission shaft drives the lower chuck to rotate, and the hemispherical protrusions of the upper and lower chucks are staggered to form a "tooth-pair vibration" structure, so that the cutting circular saw vibrates up and down at a high frequency. This design can reduce the cutting resistance, reduce tool wear, and at the same time, the incision is preliminarily polished through vibration to avoid burr residue and improve the finished product accuracy.

[0017] 3. When the cylinder rotates, the inclined ball groove drives the inclined bearing seat to swing back and forth. The swing arm drives the slide and grinding disc to swing at high frequency. The spring rod ensures that the grinding disc always fits the surface of the water pipe weld. This dynamic fit design can adapt to welds of different curvatures and achieve uniform grinding, which is particularly suitable for processing complex curved surfaces. At the same time, the polishing needle in the hollow ring is driven by the rotation of the circular magnet, forming a dynamic grinding layer inside the hollow ring. After being magnetically attracted, the needle contacts the weld closely, and the rotational motion realizes polishing without dead angles. It can effectively remove fine scratches left by grinding, significantly improve the surface finish, and meet the appearance requirements of high-precision bathroom products.

[0025] Next, in combination with the accompanying drawings of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Embodiment:

[0027] Please refer to the attached Figure 1 - attached Figure 6 , the embodiment of the present invention provides an automated production and processing device for a bathroom metal water pipe. As Figure 1 shown, it includes a processing table 1. A back plate 2 is fixedly installed at the rear side of the top end of the processing table 1 for installing various components. One side of the front end of the back plate 2 is movably installed with a movable table 3 through a guide rail. The guide rail provides linear motion guidance for the movable table 3 to ensure the cutting position accuracy. The upper side of the front end of the movable table 3 is movably installed with an upper sliding table 4, and the lower side of the front end is movably installed with a lower sliding table 5. Four corners of the bottom end of the upper sliding table 4 are connected to four corners of the top end of the lower sliding table 5 through return springs 6. The return springs 6 provide elastic buffering and cooperate with the vibration function during cutting. An electric cylinder 7 is fixedly installed at the top end of the movable table 3, and the driving end of the electric cylinder 7 is fixedly installed at the top end of the upper sliding table 4. The electric cylinder 7 is used to drive the upper sliding table 4 to move up and down to realize the feeding action of the cutting circular saw 9. One end of the lower sliding table 5 is movably installed with a cutting shaft 8, and a cutting circular saw 9 is fixedly installed at the outer end of the cutting shaft 8. The cutting circular saw 9 realizes the cutting of the pipe through the high-speed rotation of the cutting shaft 8.

[0028] Specifically, start the first motor 10. Drive the long gear 11 to rotate through the first motor 10, drive the transmission gear 13 and the transmission shaft 12 to rotate, the transmission shaft 12 drives the driving bevel gear 14 to rotate, and the rotating driving bevel gear 14 drives the driven bevel gear 15 and the cutting shaft 8 to rotate through meshing transmission, so as to drive the cutting circular saw 9 to rotate at a high speed. Subsequently, drive the upper sliding table 4 to descend through the electric cylinder 7, drive the lower sliding table 5 and the cutting circular saw 9 to descend, and cut the metal water pipe.

[0029] A transmission shaft 12 is movably installed in the middle of the lower sliding table 5. The top end of the transmission shaft 12 extends to the outside of the lower sliding table 5 and is fixedly installed with a lower chuck 16. The middle part of the bottom end of the upper sliding table 4 is fixedly installed with an upper chuck 17. A plurality of hemispherical protrusions 18 are fixedly installed on the inner sides of the lower chuck 16 and the upper chuck 17, and the positions of the two groups of hemispherical protrusions 18 are staggered with each other. The hemispherical protrusions 18 form a "tooth structure". When the transmission shaft 12 drives the lower chuck 16 to rotate, it squeezes against the protrusions of the upper chuck 17, forcing the lower sliding table 5 to vibrate at a high frequency through the return springs 6, realizing the vibration cutting function of the cutting circular saw 9, reducing the cutting resistance and grinding the cut.

[0030] Specifically, when the transmission shaft 12 rotates, it will also drive the lower chuck 16 to rotate. By utilizing the tooth-engaging structure formed by the hemispherical protrusions 18 that intersect with each other between the upper chuck 17 and the lower chuck 16, and in conjunction with the action of the return spring 6, it drives the lower slide table 5 to vibrate rapidly up and down, thereby driving the high-speed rotating cutting circular saw 9 to vibrate rapidly up and down. This can reduce the resistance during the cutting of the cutting circular saw 9, and at the same time can polish the cut, improving the quality of the final product.

[0031] At the front end of the back plate 2, near the rear side of the movable table 3, a first rotating shaft 19 is movably installed through two positioning bearing seats 20. A bidirectional spiral groove 21 is formed on the outer diameter of the middle part of the first rotating shaft 19. A round head pin 22 is fixedly installed at the rear end of the movable table 3, and the end of the round head pin 22 is movably arranged inside the bidirectional spiral groove 21. The bidirectional spiral groove 21 is composed of two reverse spiral grooves connected end to end. When the first rotating shaft 19 rotates, the round head pin 22 slides along the spiral groove, driving the movable table 3 to reciprocate linearly along the guide rail, so that the cutting circular saw 9 remains relatively stationary with the moving metal water pipe, realizing cutting without stopping the machine.

[0032] Specifically, when the first rotating shaft 19 rotates, it will also drive the bidirectional spiral groove 21 on its outer diameter to rotate. When the bidirectional spiral groove 21 rotates, it will drive the round head pin 22 to slide inside it. By utilizing the limitation of the movable table 3 by the guide rail on the back plate 2, it can drive the movable table 3 to move linearly, enabling the cutting circular saw 9 to move together with the moving metal water pipe, and the two remain relatively stationary, so that the water pipe cutting work can be completed without stopping the machine. The bidirectional spiral groove 21 is composed of two spiral grooves that are connected end to end but have opposite spiral directions. When the round head pin 22 moves to the end of one spiral groove, it will immediately enter the beginning of the other spiral groove and change the direction of movement, thereby driving the movable table 3 to reciprocate back and forth along the direction of the first rotating shaft 19. This design enables the device to perform the "forward cutting - backward reset" actions in a cycle without manual adjustment, which is suitable for large-scale continuous production scenarios and can perform continuous cutting work.

[0033] In this embodiment, a first motor 10 is fixedly installed on one side of the inner bottom of the upper sliding table 4. The driving end of the first motor 10 extends into the lower sliding table 5 and is fixedly installed with a long gear 11. An outer diameter on the upper side of the transmission shaft 12 is fixedly installed with a transmission gear 13, and the transmission gear 13 is meshed and connected to the inner end of the long gear 11. The length of the long gear 11 is slightly longer than that of the transmission gear 13. The transmission gear 13 can slide up and down along the long gear 13 direction, and ensure that the meshing transmission is uninterrupted. An outer diameter on the lower side of the transmission shaft 12 is fixedly installed with a driving bevel gear 14. The inner end of the cutting shaft 8 extends into the lower sliding table 5 and is fixedly installed with a driven bevel gear 15. The inner ends of the driving bevel gear 14 and the driven bevel gear 15 are meshed and connected. The first motor 10 drives the cutting shaft 8 and the cutting circular saw 9 to rotate at high speed through the multi-stage transmission of the long gear 11, the transmission gear 13, the transmission shaft 12, the driving bevel gear 14, and the driven bevel gear 15, ensuring stable transmission of the cutting power.

[0034] Further, a second motor 23 is fixedly installed on one side of the front end of the back plate 2 close to the first rotating shaft 19, and the driving end of the second motor 23 is fixedly installed at one end of the first rotating shaft 19. A first worm 24 is fixedly installed at the end of the first rotating shaft 19. An activity shaft 25 is movably installed at a position below the first worm 24 on the front end of the back plate 2. A first worm gear 26 is fixedly installed on the outer diameter of the middle part of the activity shaft 25, and the first worm gear 26 is meshed and connected to the inner end of the first worm 24. The second motor 23 drives the first rotating shaft 19 to rotate. Through the meshing transmission of the first worm 24 and the first worm gear 26, the activity shaft 25 is driven to rotate, and then the upper guide wheel 27 is driven to rotate, realizing the transportation of materials.

[0035] Further, an upper guide wheel 27 is fixedly installed at the front end of the activity shaft 25. A lower guide wheel 28 is fixedly installed at a position below the upper guide wheel 27 on the top end of the processing table 1. The bottom of the lower guide wheel 28 can be supported by a spring to ensure the fitting of the material. The upper guide wheel 27 and the lower guide wheel 28 form a feeding clamping structure. When the upper guide wheel 27 rotates, it drives the metal water pipe to move forward. The synchronous movement of the two ensures uniform and stable feeding speed. A material supporting table 29 is fixedly installed at a position below the activity table 3 on the top end of the processing table 1. The material supporting table 29 is used to support the cut pipe to prevent it from falling and being damaged.

[0036] Specifically, start the second motor 23. The second motor 23 drives the first rotating shaft 19 to rotate, driving the first worm 24 at the end to rotate. The first worm 24 drives the first worm gear 26 and the activity shaft 25 to rotate through meshing transmission, thereby driving the upper guide wheel 27 to rotate. The rotating upper guide wheel 27 and the lower guide wheel 28 cooperate to drive the metal water pipe to move forward.

[0037] Further, one side of the top end of the processing table 1 is fixedly installed with a grinding box 30 through a bracket. A second rotating shaft 31 is movably installed on the upper side inside the grinding box 30. A cylinder block 32 is fixedly installed on the outer diameter of one side of the second rotating shaft 31. An inclined ball groove is formed on the outer diameter of the cylinder block 32, and an inclined bearing seat 33 is movably installed in the ball groove. A swing rod 34 is fixedly installed at the bottom end of the inclined bearing seat 33. The swing rod 34 can adopt a combination of an inner rod and an outer rod to ensure normal swinging. A sliding seat 36 is movably installed on the lower side inside the grinding box 30 through two guide rods 35. The bottom end of the swing rod 34 is movably installed at the top end of the sliding seat 36. A grinding disc 38 is installed at the bottom end of the sliding seat 36 through four spring rods 37. When the second rotating shaft 31 drives the cylinder block 32 to rotate, the inclined ball groove forces the inclined bearing seat 33 to reciprocate along the axis of the cylinder block 32. The sliding seat 36 is driven to slide on the guide rods 35 through the swing rod 34. The spring rods 37 make the grinding disc 38 always fit the weld of the pipe. High-frequency swinging realizes efficient grinding.

[0038] Specifically, start the third motor 46. Drive the second rotating shaft 31 to rotate through the third motor 46, and drive the cylinder block 32 to rotate. Since there is an included angle between the ball groove on the outer diameter of the cylinder block 32 and the central axis of the cylinder block 32, when the cylinder block 32 rotates, it will drive the inclined bearing seat 33 to reciprocate. Through the action of the swing rod 34, the sliding seat 36 is driven to move accordingly. The spring rods 37 at the bottom of the sliding seat 36 will attach the grinding disc 38 to the surface of the weld of the metal water pipe and drive the grinding disc 38 to reciprocate quickly, realizing the grinding work on the surface weld of the metal water pipe.

[0039] Further, a hollow ring 39 is fixedly installed on one side inside the grinding box 30. A polishing magnetic needle 40 is filled inside the hollow ring 39. An opening 45 is formed at the bottom end of the hollow ring 39. A short shaft 41 is movably installed on one side of the inner wall of the grinding box 30 close to the hollow ring 39. The end of the short shaft 41 extends to the central position inside the hollow ring 39 and is fixedly installed with a circular magnet 42. The polishing magnetic needle 40 contacts the surface of the pipe through the opening 45. When the circular magnet 42 rotates, it generates a magnetic field, adsorbs and drives the magnetic needle to move cyclically inside the hollow ring 39, realizing the fine polishing of the weld surface.

[0040] Further, a second worm gear 43 is fixedly installed on the outer diameter of the middle part of the short shaft 41, a second worm 44 is fixedly installed on the outer diameter of the other side of the second rotating shaft 31, and the second worm 44 is meshed and connected to the inner side end of the second worm gear 43. One end of the grinding box 30 is fixedly installed with a third motor 46, and the driving end of the third motor 46 is fixedly installed at one end of the second rotating shaft 31. The third motor 46 drives the second rotating shaft 31 to rotate. Through the transmission of the second worm 44 and the second worm gear 43, the short shaft 41 and the circular magnet 42 are synchronously driven to rotate, realizing the power linkage of the polishing action and the grinding action. Insertion ports 47 are opened on the lower sides of both ends of the grinding box 30. The insertion ports 47 are used for the metal water pipe to enter and exit the grinding box 30, realizing a full-automatic grinding and polishing process.

[0041] Specifically, the polished metal water pipe will enter below the hollow ring 39. The polishing magnetic needle 40 in the hollow ring 39 contacts the weld on the surface of the metal pipe through the opening 45. When the second rotating shaft 31 rotates, it will also drive the second worm 44 to rotate. The second worm 44 drives the second worm gear 43 and the short shaft 41 to rotate. The short shaft 41 drives the circular magnet 42 to rotate. The circular magnet 42 will adsorb the polishing magnetic needle 40 and drive the polishing magnetic needle 40 to move in the hollow ring 39, thereby polishing the weld on the surface of the metal water pipe.

[0042] Working principle: The formed metal water pipe after roll welding is passed through the insertion port 47 of the grinding box 30, and then passes between the upper guide wheel 27 and the lower guide wheel 28 and finally is placed on the surface of the material placing table 29. Subsequently, the second motor 23 is started, and the first rotating shaft 19 is driven to rotate through the second motor 23, driving the first worm 24 at the end to rotate. The first worm 24 drives the first worm gear 26 and the movable shaft 25 to rotate through meshing transmission, thereby driving the upper guide wheel 27 to rotate. The rotating upper guide wheel 27 and the lower guide wheel 28 cooperate to drive the metal water pipe to move forward. Subsequently, the third motor 46 is started, and the second rotating shaft 31 is driven to rotate through the third motor 46, driving the cylinder block 32 to rotate. Since there is an angle between the ball groove on the outer diameter of the cylinder block 32 and the central axis of the cylinder block 32, when the cylinder block 32 rotates, it will drive the inclined bearing seat 33 to swing reciprocally. Then, through the action of the swing rod 34, the slide seat 36 is driven to move accordingly. The spring rod 37 at the bottom of the slide seat 36 will attach the grinding disc 38 to the surface of the weld of the metal water pipe and drive the grinding disc 38 to swing reciprocally rapidly, realizing the grinding work on the surface weld of the metal water pipe. The ground metal water pipe will enter below the hollow ring 39. The polishing magnetic needle 40 in the hollow ring 39 contacts the weld on the surface of the metal pipe through the opening 45. When the second rotating shaft 31 rotates, it will also drive the second worm 44 to rotate. The second worm 44 drives the second worm gear 43 and the short shaft 41 to rotate. The short shaft 41 drives the circular magnet 42 to rotate. The circular magnet 42 will adsorb the polishing magnetic needle 40 and drive the polishing magnetic needle 40 to move within the hollow ring 39, thereby polishing the weld on the surface of the metal water pipe. The ground and polished metal water pipe is moved to below the movable table 3 through the transmission of the upper guide wheel 27 and the lower guide wheel 28. At this time, the first motor 10 is started, and the long gear 11 is driven to rotate through the first motor 10, driving the transmission gear 13 and the transmission shaft 12 to rotate. The transmission shaft 12 drives the driving bevel gear 14 to rotate. The rotating driving bevel gear 14 drives the driven bevel gear 15 and the cutting shaft 8 to rotate through meshing transmission, thereby driving the cutting circular saw 9 to rotate at a high speed. Subsequently, the upper slide table 4 is driven to descend through the electric cylinder 7, driving the lower slide table 5 and the cutting circular saw 9 to descend to cut the metal water pipe. When the transmission shaft 12 rotates, it will also drive the lower chuck 16 to rotate. Utilizing the toothed structure formed by the hemispherical protrusions 18 that intersect with each other between the upper chuck 17 and the lower chuck 16, and with the cooperation of the reset spring 6, the lower slide table 5 is driven to vibrate rapidly up and down, thereby driving the high-speed rotating cutting circular saw 9 to vibrate rapidly up and down, which can reduce the resistance when the cutting circular saw 9 cuts and can also polish the cut, improving the quality of the later finished product. In addition, when the first rotating shaft 19 rotates, it will also drive the double helical groove 21 on its outer diameter to rotate. When the double helical groove 21 rotates, it will drive the round head pin 22 to slide inside it. By using the limit of the guide rail on the back plate 2 to the movable table 3, the movable table 3 can be driven to move linearly, enabling the cutting circular saw 9 to move along with the moving metal water pipe. The two remain relatively stationary, and the water pipe cutting work can be completed without stopping the machine.The bi-directional spiral groove 21 is composed of two spiral grooves that are connected end to end but have opposite spiral directions. When the round head pin 22 moves to the end of one spiral groove, it will immediately enter the beginning of the other spiral groove and change its movement direction, thereby driving the movable table 3 to reciprocate back and forth along the direction of the first rotating shaft 19. When moving to the right, it descends for cutting, and when moving to the left, it rises for resetting, enabling continuous cutting work.

[0043] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
