[0002] Metal is a substance that has lustre (i.e. strong reflection of visible light), is ductile, and is easy to conduct electricity and heat.

Metals are widely present in nature and are widely used in life. They are a very important and most widely used type of substance in modern industry.

A preheating mechanism 8 is provided at the adjacent ends of the fixing fixture 6 and the driving fixture 5, and a grinding mechanism 7 is provided inside the fixing fixture 6 and the driving fixture 5.

[0043] By adopting the above technical scheme, the fixing mechanism is composed of a fixing component 1 2 and a fixing component 2 9. The fixing component 1 2 is used for fixing the processing of non-magnetic metal pipes, and the fixing component 2 9 is used for fixing the processing of magnetic metal pipes. The two can respectively cooperate with the grinding mechanism 7 and the preheating mechanism 8 to grind and preheat the pipes to be processed inside the driving fixture 5 and the fixing fixture 6, and cooperate with the driving disk 12 to rotate the driving fixture 5 to bend the pipe. The present invention can comprehensively grind and polish the surface of the pipe to be processed by designing a fixing mechanism to cooperate with the grinding mechanism 7 to clean up the residual impurities and rust marks such as iron filings on the surface, which is convenient for subsequent manual spraying of protective coatings, replacing the manual grinding treatment method, and combining multiple processing steps to improve the processing efficiency of the device.

[0044] As an embodiment of the present invention, Figure 2 and Figure 4 As shown, the fixing assembly 2 includes an outer turntable 27 fixedly connected to the front end of the driving fixture 5, the inner turntable 22 is rotatably connected to the inner turntable 22 in an embedded manner inside the outer turntable 27, a slide groove 23 is provided on the rear end surface of the inner turntable 22, a fixing block 21 is slidably connected inside the slide groove 23, the rear end of the fixing block 21 extends to the inside of the driving fixture 5, a threaded hole 24 is provided at one end of the fixing block 21 located inside the slide groove 23, a threaded rod 25 with a bidirectional thread structure is spirally connected inside the threaded hole 24, and the outer surface of the outer turntable 27 corresponds to the position of the slide groove 23. A plug-in hole 26 is provided, and the plug-in hole 26 corresponds to the internal threaded rod 25 of the slide groove 23. The top of the threaded rod 25 is rotatably connected to the inner wall of the slide groove 23 through a ball bearing. The built-in hexagonal hole on the top corresponds to the plug-in hole 26. The front end of the outer turntable 27 is designed to be open, and the front end of the outer turntable 27 is screwed with an end cover 28. The output shaft of the motor 4 passes through the outer end cover 28 and is fixed to the middle part of the front end surface of the inner turntable 22. The fixed block 21 and the slide groove 23 are T-shaped structures that match each other and are slidably connected. The end of the fixed block 21 away from the threaded hole 24 is inclined.

[0045] By adopting the above technical solution, when working, the user selects the corresponding fixing mechanism according to the characteristics of the pipe to be processed. For example, when the metal pipe to be processed is an aluminum alloy non-magnetic metal pipe, the user fixes the fixing component 2 on the front end of the driving fixture 5, and then the user pushes the pipe through the rear end inlet of the fixing fixture 6 to the inside of the driving fixture 5. At this time, the two fixing blocks 21 in the fixing component 2 are located inside one end of the hollow pipe. At this time, the user inserts the external tool into the inner hexagon of the upper end of the threaded rod 25 through the plug hole 26. In the corner hole, the threaded rod 25 is driven to rotate by rotation. At this time, one end of the fixed block 21 connected to the threaded rod 25 by spiral transmission is displaced in the opposite direction in the slide groove 23, and then reaches the inner wall of the hollow tube to firmly fix the hollow tube. Then the user pulls the tool out of the plug hole 26. At this time, the user controls the motor 4 to rotate in both directions, and then controls the inner turntable 22 through the output shaft of the motor 4 to cooperate with the fixed block 21 that fixes the inner wall of the hollow tube to carry the hollow tube to the fixing fixture 6 and the grinding mechanism 7 inside the driving fixture 5 to grind and polish the surface of the tube.

[0046] As an embodiment of the present invention, Figure 3 As shown, the fixing component 2 9 includes an outer turntable 2 91 fixedly connected to the front end of the driving fixture 5, the front end of the outer turntable 2 91 is designed to be open, and the front end of the outer turntable 2 91 is screwed with an end cover 2 94, the motor 4 is fixed to the front end of the end cover 2 94, an electromagnet 93 is embedded in the interior of the outer turntable 2 91, and the motor 4 passes through the end cover 2 94 and is fixed to the electromagnet 93, the rear end of the electromagnet 93 is located inside the driving fixture 5, and a bearing 92 is fixed between the electromagnet 93 and the outer turntable 2 91 and is rotatably connected through the bearing 92.

[0047] By adopting the above technical solution, when the metal pipe to be processed is made of magnetic metal material, the installation and fixing component 2 9 can be replaced. The installation principle of the metal pipe to be processed is consistent with the above steps. Then, the electromagnet 93 is mainly used for conducting electricity to generate magnetic force to firmly adsorb and fix one end of the metal pipe to be processed, and the grinding mechanism 7 is used to realize the grinding and polishing of the surface of the pipe.

[0048] As an embodiment of the present invention, Figure 2 and Figure 6 As shown, the preheating mechanism 8 includes a high-frequency heating tube 81 fixedly connected to the inner wall of the fixing fixture 6, and both ends of the high-frequency heating tube 81 extend to one side of the fixing fixture 6 and are fixedly connected with a joint 82.

[0049] By adopting the above technical solution, at the same time, the user also controls the preheating mechanism 8 to conduct electricity, and then the high-frequency heating tube 81 conducts electricity to preheat the internal pipe area to be bent. The present invention can preheat the area to be bent of the pipe to be processed by designing the preheating mechanism 8, thereby increasing the stress pulling of the metal pipe in the subsequent bending process, reducing the fracture at the bending part of the pipe and the tensile damage invisible to the naked eye, thereby improving the processing qualification rate.

[0050] As an embodiment of the present invention, Figure 2 and Figure 5 As shown, the grinding mechanism 7 includes a mounting groove 75 opened inside the driving clamp 5 and the fixing clamp 6, the inner wall of the mounting groove 75 is detachably connected with a grinding piece 74, the grinding piece 74 is designed in a C-shaped structure, the left end faces of the driving clamp 5 and the fixing clamp 6 are detachably connected with a sealing plate 71, the bottom of the sealing plate 71 and the driving clamp 5 and the fixing clamp 6 are fixed with hinges 73, and the top of the sealing plate 71 is magnetically fixed to the driving clamp 5 and the fixing clamp 6 by an electromagnetic block, and the electromagnetic block is embedded in the sealing plate 71, and high-temperature resistant airbags 72 are glued between the movable ends of the grinding piece 74 and the inner wall of the mounting groove 75, and the inflation tube of the high-temperature resistant airbag 72 extends to the right end face of the fixing clamp 6 and the driving clamp 5, the high-temperature resistant airbag 72 is made of high-temperature resistant rubber material, and the grinding piece 74 includes an outer layer of heat-insulating elastic metal sheet glued to the high-temperature resistant airbag 72 and an inner layer of grinding sandpaper.

[0051] By adopting the above technical solution, the sandpaper on the inner layer of the grinding piece 74 in the grinding mechanism 7 can effectively rub and clean the impurities on the surface of the pipe. At the same time, the user can also adjust the grinding mechanism 7 according to the diameter of the pipe to be processed so that the grinding piece 74 fits tightly to the outer surface of the pipe. The specific operation is that the user connects the air inlet pipe to the external air pump, and then delivers gas to the inside of the high-temperature resistant airbag 72. The expansion of the high-temperature resistant airbag 72 further squeezes the active end of the grinding piece 74 inward. Since the grinding piece 74 is an elastic grinding sheet, it can be deformed inward under the action of its own elastic deformation and make its inner sandpaper layer fit tightly to the outer surface of the wrapped pipe, and cooperate with the fixing mechanism to realize the grinding and polishing operation of the pipe surface. The device structure can further adjust the grinding mechanism 7 according to the diameter of the pipe to be processed so that it fits the pipe fitting, thereby achieving a better grinding effect.

[0052] As an embodiment of the present invention, Figure 7 and Figure 8As shown, a detection mechanism 3 is also provided on the front side of the driving disk 12. The driving disk 12 carries the driving clamp 5 to detect the bending curvature during the bending forming process of the internal pipe. The detection mechanism 3 includes a guide groove 31 provided on the upper end surface of the processing table 1, and a guide block 33 is slidably connected to the inside of the guide groove 31. The upper end of the guide block 33 is rotatably connected to a rotating shaft 32. The upper end surface edge of the guide groove 31 is provided with a curvature scale line 35, and a spring 34 is fixedly connected between the guide groove 31 and the guide block 33.

[0053] By adopting the above technical solution, after the preheating and grinding work is completed, the threaded rod 25 is rotated in the opposite direction, so that the fixing block 21 is loosened, the front end of the pipe loses the tension clamping, the front end motor 4 of the driving fixture 5 stops running, and the servo motor 13 installed inside the processing table 1 is connected to the driving disk 12 on the surface of the processing table 1. The servo motor 13 is controlled to drive the driving disk 12 to rotate counterclockwise, thereby carrying the driving fixture 5 to rotate and displace, and the pipe is bent and formed. During the bending process, as the pipe bends, the driving fixture 5 will touch the rotating shaft 32 in the detection mechanism 3, and then squeeze the rotating shaft 32. As the arc deflection displacement of the driving fixture 5, the rotating shaft 32 itself will also rotate to reduce the extrusion friction between the two. At the same time, the guide block 33 at the lower end of the rotating shaft 32 is displaced inside the guide groove 31, and in this process, the internal spring 34 is pulled. Then, after the bending is finalized, the curvature of the pipe is understood by observing the value of the scale line 35 corresponding to the edge of the rotating shaft 32, so as to prevent the rebound phenomenon after the pipe is bent, which causes a large bending error and affects the product qualification.

[0054] Working principle: During operation, the user selects a corresponding fixing mechanism according to the characteristics of the pipe to be processed. For example, when the metal pipe to be processed is an aluminum alloy non-magnetic metal pipe, the user fixes the fixing component 2 on the front end of the driving fixture 5, and then pushes the pipe through the rear end inlet of the fixing fixture 6 to the inside of the driving fixture 5. At this time, the two fixing blocks 21 in the fixing component 2 are located inside one end of the hollow pipe. At this time, the user inserts the external tool into the hexagonal hole at the upper end of the threaded rod 25 through the plug hole 26. The threaded rod 25 is driven to rotate, and one end of the fixed block 21 connected to the threaded rod 25 is displaced in the opposite direction in the slide groove 23, and then reaches the inner wall of the hollow pipe to firmly fix the hollow pipe. Then the user pulls the tool out of the plug hole 26. At this time, the user controls the motor 4 to rotate in both directions, and then controls the inner turntable 22 through the output shaft of the motor 4 to cooperate with the fixed block 21 that fixes the inner wall of the hollow pipe to carry the hollow pipe in the fixing fixture 6 and the driving fixture 5 to cooperate with the grinding mechanism 7 to grind and polish the surface of the pipe.

[0055] When the metal pipe to be processed is a magnetic metal material, the second installation fixing component 9 can be replaced. The installation principle of the metal pipe to be processed is consistent with the above steps. Then, the electromagnet 93 is mainly used for conducting and operating to generate magnetic force to firmly adsorb and fix one end of the metal pipe to be processed, and the grinding mechanism 7 is used to grind and polish the surface of the pipe.

[0056] The sandpaper on the inner layer of the grinding piece 74 in the grinding mechanism 7 can effectively clean the impurities on the surface of the pipe by friction. At the same time, the user can also adjust the grinding mechanism 7 according to the diameter of the pipe to be processed so that the grinding piece 74 fits tightly to the outer surface of the pipe. The specific operation is that the user connects the air inlet pipe to the external air pump, and then delivers gas to the inside of the high-temperature resistant airbag 72. The expansion of the high-temperature resistant airbag 72 further squeezes the active end of the grinding piece 74 inward. Since the grinding piece 74 is an elastic grinding sheet, it can deform inward under the action of its own elastic deformation and make the inner sandpaper layer fit tightly to the outer surface of the wrapped pipe, and cooperate with the fixing mechanism to realize the grinding and polishing operation of the pipe surface. At the same time, the user also controls the preheating mechanism 8 to conduct electricity, and then the high-frequency heating tube 81 conducts electricity to preheat the internal pipe surface to be bent.

[0057] After the preheating and grinding work is completed, the threaded rod 25 is rotated in the reverse direction to loosen the fixing block 21, and the front end of the pipe loses the tension and clamping, and the front end motor 4 of the driving fixture 5 stops running. The servo motor 13 installed inside the processing table 1 is connected to the driving disk 12 on the surface of the processing table 1. The servo motor 13 is controlled to drive the driving disk 12 to rotate counterclockwise, thereby carrying the driving fixture 5 to rotate and move, and the pipe is bent and formed. During the bending process, as the pipe bends, the driving fixture 5 will touch the rotating shaft 32 in the detection mechanism 3, and then squeeze the rotating shaft 32. As the rotating shaft 32 is deflected and displaced in an arc shape by the driving fixture 5, the rotating shaft 32 itself will also rotate to reduce the extrusion friction between the two. At the same time, the guide block 33 at the lower end of the rotating shaft 32 is displaced inside the guide groove 31, and in this process, the internal spring 34 is pulled. After bending and shaping, the curvature of the pipe is understood by observing the value of the scale line 35 corresponding to the edge of the rotating shaft 32. The curvature is calculated by the deflection angle of the driving fixture 5 and the displacement scale value of the rotating shaft 32, so as to prevent the rebound phenomenon after the pipe is bent, which will cause a large bending error and affect the product quality.

[0058] After the bending of the tube is completed, the controller connected to the electromagnetic block controls the electromagnetic block to cut off the power, and then the user flips the sealing plate 71 downward. At this time, the openings on the left end faces of the driving clamp 5 and the fixing clamp 6 are opened, and the user takes out the tube bent inside through the opening. After taking it out, the sealing plate 71 is flipped over again to cover the opening, and then the electromagnetic block is used to guide the electromagnetic attraction to fix the sealing plate 71, and then the servo motor 13 rotates in the opposite direction to drive the clamp 5 to reverse the deflection displacement and reset.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
