The advancement of modern manufacturing technology, such as computer numerical control and laser cutting and welding, has improved production accuracy and efficiency, meeting the needs of rapid production. At the same time, the improvement of global environmental awareness has prompted equipment to develop in a more energy-saving and low-emission direction to meet strict environmental standards. In the fierce market competition, companies have reduced costs, shortened delivery time and enhanced competitiveness through efficient and automated production and molding equipment. In addition, the application areas of bellows are also constantly expanding, covering emerging industries such as automobiles, aviation, and electronics, which has promoted the diversification and specialization of equipment.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] For example, see Figure 1-Figure 12 The present invention discloses a production and molding equipment for metal corrugated pipes, comprising an operating table 1, a lower mold block 2 is arranged in the middle above the operating table 1, auxiliary push rods 14 for assisting the molding of the corrugated pipe are installed on both sides of the operating table 1, a support table 11 is fixedly connected to one side of the operating table 1, a support column 13 is arranged on the lower side of the support table 11, an upper mold block 21 is slidably connected to the support column 13, a first hydraulic rod 12 is fixedly connected to the lower side of the upper mold block 21, and one end of the first hydraulic rod 12 is fixedly connected to the upper side of the upper mold block 21.

[0039] The design of the first hydraulic rod 12 enables the upper mold block 21 to be molded with the lower mold block 2, so that the mold can form a closed whole. At the same time, the design of the support column 13 makes the sliding of the upper mold block 21 more stable to prevent deviation.

[0040] The two ends of the pipe are squeezed by auxiliary push rods 14 on both sides, and water is injected into the interior of the pipe. The auxiliary push rods 14 form a closed cavity inside the pipe, so that the high-pressure liquid can act evenly on the inner wall of the tube blank. At the same time, the auxiliary push rods 14 at both ends are used to squeeze the pipe, so that corrugations can be formed at the corrugated groove 23 of the mold.

[0041] See Figure 5 A groove 23 is provided on the lower mold block 2, a fixed tube 24 is provided inside the groove 23, a second hydraulic rod 3 is installed inside the fixed tube 24, the output end of the second hydraulic rod 3 is rotatably connected to a rotating column 31, and the other end of the rotating column 31 is hinged with an arc-shaped adsorption block 33, the arc-shaped adsorption block 33 is used to adsorb the formed metal corrugated pipe, the arc-shaped adsorption block 33 is slidably connected to the groove 23, and the arc-shaped adsorption block 33 has a certain arc shape. After the pipeline is formed, the arc-shaped adsorption block 33 is driven by the second hydraulic rod 3 to slide in the groove 23, and the pipeline is lifted by the arc-shaped adsorption block 33. Through such a design, the pipeline can be automatically separated from the mold shell after forming, reducing manual operation and improving production efficiency to a certain extent;

[0042] One side of the lower mold block 2 is provided with an inclined groove 22 for easy material discharge. The design of the inclined groove 22 enables automatic material discharge after subsequent pipe forming, which can reduce manual intervention to a certain extent and improve production efficiency.

[0043] See Figure 7 A suction hole 36 is provided on the arc-shaped suction block 33, a sealing plate 4 is arranged inside the arc-shaped suction block 33, a sealing column 41 is fixedly connected to one side of the sealing plate 4, the sealing column 41 is intermittently plugged into the suction hole 36, a sliding column 43 is fixedly connected to one side of the sealing plate 4, a sliding tube 44 is slidably connected to the other end of the sliding column 43, the other end of the sliding tube 44 is fixedly installed inside the arc-shaped suction block 33, and a first inclined surface 46 is arranged at one end of the sealing plate 4 close to the air pipe 51.

[0044] See Figure 8 An oil storage bin 317 is provided inside the rotating column 31, one end of the oil storage bin 317 is connected to an oil delivery hose 45, one end of the oil delivery hose 45 is connected to the sliding tube 44, a sealing disk 318 is slidably connected inside the oil storage bin 317, a sliding rod 319 is fixedly connected to one side of the sealing disk 318, a ball 320 for reducing friction is rotatably provided on the other end of the sliding rod 319, a resisting arc plate 29 is provided on the upper side of the sliding rod 319, the lower side of the resisting arc plate 29 resists the ball 320, a first spring 28 is fixedly connected to the upper side of the resisting arc plate 29, and the other end of the first spring 28 is fixedly connected to the inside of the fixed tube 24, as shown in FIG. Figure 8 As shown, during the upward sliding of the rotating column 31, the oil storage bin 317 will be driven to slide together, and the sealing plate 318 can slide in the oil storage bin 317 through the resistance of the arc plate 29 to the ball 320 on the sliding rod 319, so that the hydraulic oil in the oil storage bin 317 can be squeezed into the oil delivery hose 45, and at the same time, the hydraulic oil enters the sliding tube 44 through the oil delivery hose 45. Under the action of the hydraulic oil, the sliding column 43 drives the sealing plate 4 to slide, and the sliding of the sealing plate 4 drives the sealing column 41 to slide out of the adsorption hole 36. At this time, the first protruding column 32 slides in the first straight slide groove 251.

[0045] An air pump 5 is provided on the side of the fixed pipe 24 away from the oil delivery hose 45. The air pump 5 is arranged inside the groove 23. The air pump 5 is connected to an air pipe 51. An air hole 42 is opened on the sealing plate 4. The arc-shaped adsorption block 33 is connected to the air pipe 51 on the side close to the rotating column 31. After the sealing column 41 slides out of the adsorption hole 36, the air pump 5 is started at this time, and the suction force is transmitted to the arc-shaped adsorption block 33 through the air pipe 51. At the same time, under the action of the air hole 42, the adsorption hole 36 generates adsorption force, so that the corrugated metal pipe can be firmly adsorbed on the arc-shaped adsorption block 33.

[0046] In this embodiment: the blocking design of the adsorption hole 36 by the blocking column 41 ensures that the metal pipe will not be deformed under high pressure due to the opening of the adsorption hole 36 during the forming process; at the same time, the fixing of the blocking plate 4 by the sliding block 37 can prevent the blocking column 41 and the blocking plate 4 from sliding under high pressure during the forming process of the metal pipe, thereby preventing the metal pipe from deforming. Such a design can ensure that the metal pipe will not deviate during the corrugation forming process as much as possible; the design of the air pump 5, the air pipe 51, the air hole 42 and the adsorption hole 36 ensures that the formed metal pipe can be firmly adsorbed on the arc adsorption block 33, which can prevent the metal pipe from escaping from the adsorption of the arc adsorption block 33 during the subsequent swinging;

[0047] Moreover, through the design of the first spring 28 and the arc-shaped plate 29, when the rotating column 31 starts to slide upward, the hydraulic oil in the oil storage tank 317 can be transferred to the sliding tube 44, so that the arc-shaped adsorption block 33 first adsorbs and fixes the metal pipe after forming the corrugation, and then pushes the metal pipe out of the mold shell to prevent the corrugated pipe from being separated from the fixation of the arc-shaped adsorption block 33 during the pushing process. At the same time, the arc-shaped plate 29 is as shown in FIG. Fig.10 The arc shape shown enables the arc-shaped plate 29 to keep in contact with the ball 320 during the subsequent rotation of the rotating column 31 .

[0048] Embodiment 2: This embodiment is intended to solve the problem that too much water will remain inside the metal pipe after the corrugation is formed. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 12 A sliding block 37 for limiting the blocking plate 4 is slidably provided on one side of the arc-shaped adsorption block 33, and a snap-fitting groove 26 for slidingly connecting with the sliding block 37 is provided on the side wall of the groove 23. A second inclined surface 27 is provided on the upper end of the snap-fitting groove 26, and a second spring 310 is provided on the side of the sliding block 37 away from the snap-fitting groove 26. The second spring 310 is a tension spring, and one end of the second spring 310 is fixedly connected to the inner wall of the arc-shaped adsorption block 33, such as Figure 6 When the rotating column 31 drives the arc-shaped adsorption block 33 to slide upward, when the arc-shaped adsorption block 33 drives the sliding block 37 to slide to the engaging groove 26, the sliding block 37 will first slide into the engaging groove 26 under the action of the second spring 310, and at the same time, the other end of the sliding block 37 releases the resistance of the sliding tube 44, so that the blocking plate 4 can slide.

[0049] See Figure 7 A third inclined surface 38 is provided on a side of the sliding block 37 close to the engaging groove 26, and a fourth inclined surface 39 is provided on a side of the sliding block 37 close to the second spring 310, and the fourth inclined surface 39 is used to abut against the first inclined surface 46;

[0050] When one end of the sliding block 37 is located in the engaging groove 26, the sliding block 37 releases the restriction on the blocking plate 4. Through the design of the second inclined surface 27, after the sliding block 37 releases the resistance to the blocking plate 4, as the arc-shaped adsorption block 33 continues to slide upward, the second inclined surface 27 resists one end of the sliding block 37, so that the sliding block 37 slides into the arc-shaped adsorption block 33, thereby not affecting the arc-shaped adsorption block 33 from sliding out of the lower mold block 2.

[0051] A first protruding column 32 and a second protruding column 321 are respectively provided on both sides of the rotating column 31, and a sliding groove 25 is provided on both sides of the inner wall of the fixed tube 24. The first protruding column 32 and the second protruding column 321 are slidably connected with the sliding groove 25. The sliding groove 25 includes a first straight groove 251, a spiral groove 252, a second straight groove 253 and a protruding block 254. The first straight groove 251, the spiral groove 252, and the second straight groove 253 are connected to each other, and the protruding block 254 is located in the spiral groove 252;

[0052] When the first protruding column 32 slides in the spiral sliding groove 252 , the rotating column 31 drives the arc-shaped adsorption block 33 to rotate.

[0053] As the second hydraulic rod 3 continues to drive the rotating column 31 to slide upward, when the rotating column 31 drives the first protruding column 32 to slide into the spiral groove 252, the spiral design of the spiral groove 252 allows the first protruding column 32 to drive the rotating column 31 to rotate. While the rotating column 31 rotates, it also drives the arc-shaped adsorption block 33 and the metal bellows on the arc-shaped adsorption block 33 to rotate together.

[0054] In this embodiment: the arc-shaped adsorption block 33 drives the metal bellows to rotate together, so that after the metal bellows is formed, the centrifugal force can be used to throw out the residual water in the pipeline by rotating the bellows, thereby reducing the corrosion and pollution of the inner wall of the pipeline by the water, improving the cleanliness and service life of the pipeline, and making the inner wall of the pipeline drier. At the same time, through the design of the third inclined surface 38, when the arc-shaped adsorption block 33 slides into the groove 23, the sliding block 37 can slide into the arc-shaped adsorption block 33 through the resistance of the third inclined surface 38, thereby not affecting the arc-shaped adsorption block 33 sliding into the groove 23. At the same time, through the design of the fourth inclined surface 39 and the first inclined surface 46, the third inclined surface 38 is in contact with the first inclined surface 46. Fig.10 When the lower end of the engaging groove 26 shown in the figure comes into contact, the fourth inclined surface 39 can come into contact with the first inclined surface 46 during the process of the sliding block 37 sliding into the arc-shaped adsorption block 33, so that the blocking plate 4 can drive the blocking column 41 to completely block the adsorption hole 36, and at the same time, the sliding block 37 will not get stuck during the process of sliding into the arc-shaped adsorption block 33.

[0055] Moreover, through the design of the first straight slide groove 251, the arc-shaped adsorption block 33 can slide out of the lower mold block 2 with the metal bellows and then rotate, which can effectively prevent the lower mold block 2 from affecting the rotation of the metal bellows, so that the residual water in the metal bellows can be thrown out more thoroughly, further improving the effect of driving the bellows to throw out the water.

[0056] Embodiment 3: This embodiment is intended to solve the problem that a lot of water will remain in the metal pipe after the corrugation is formed. This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-Figure 12 The first raised column 32 is internally slidably connected with a resistance column 315, one end of which is fixedly connected with a resistance bevel 314, which is located inside the first raised column 32, and a third spring 316 is sleeved on the resistance column 315, which is installed inside the first raised column 32, and the resistance column 315 is used for sliding connection with the first straight slide groove 251, the spiral slide groove 252 and the second straight slide groove 253.

[0057] When the first protruding column 32 contacts the protruding block 254 , the arc-shaped adsorption block 33 swings.

[0058] See Fig. 9 The interior of the rotating column 31 is slidably connected with a control rod 311, and a resistance block 312 is provided at one end of the control rod 311 close to the resistance inclined block 314. One side of the resistance block 312 is in resistance with the inclined surface of the resistance inclined block 314, and a fourth spring 313 is provided below the resistance block 312. Through the design of the third spring 316, when the resistance column 315 does not conflict with the protruding block 254, the third spring 316 can pull the resistance column 315 to return to its original position. At the same time, through the design of the fourth spring 313, when the resistance block 312 is not in resistance with the inclined surface of the resistance inclined block 314, the fourth spring 313 can push the resistance block 312 to return to its original position under the action of the fourth spring 313.

[0059] A fixed slider 35 is provided at one end of the control rod 311 close to the arc-shaped adsorption block 33, and the fixed slider 35 is rotatably connected to the pull rod 34. The other end of the pull rod 34 is hinged to the bottom side of the arc-shaped adsorption block 33, and the interference column 315 interferes with the raised block 254 in the spiral groove 252, so that the interference column 315 slides toward the inside of the first raised column 32, so that the inclined surface of the interference inclined block 314 interferes with the interference block 312, so that the interference block 312 drives the control rod 311 and the fixed slider 35 to slide downward. During the sliding process of the fixed slider 35, the pull rod 34 will be pulled to slide together, and the arc-shaped adsorption block 33 will swing by pulling the pull rod 34 to slide.

[0060] At the same time, a protrusion 254 is also provided at the end of the second straight slide groove 253. Fig.11 As shown, when the rotating column 31 drives the first protruding column 32 to slide from the spiral slide groove 252 into the second straight slide groove 253, as the rotating column 31 drives the first protruding column 32 to continue to rise, the interference column 315 interferes with the protruding block 254 in the second straight slide groove 253, so that the arc-shaped adsorption block 33 is pulled by the pull rod 34, and the arc-shaped adsorption block 33 tilts toward the inclined groove 22 with the metal corrugated pipe, and then the air pump 5 is turned off to make the metal bellows lose adsorption, so that the metal bellows can be automatically unloaded through the guidance of the inclined groove 22.

[0061] In the present embodiment: the arc-shaped adsorption block 33 drives the metal bellows to rotate and swing at the same time. The rotation and swinging of the rotating bellows can more quickly throw out the moisture on the inner wall of the pipe, which can accelerate the process of pipe drying. The surface water accumulation on the inner wall of the pipe is reduced, thereby accelerating the evaporation rate of the moisture, making the pipe dry faster, and at the same time, the residual water inside the pipe can be thrown out more thoroughly, which can facilitate the subsequent storage of the metal pipe; through the rotation and swinging of the metal bellows, the residual water in the metal bellows is further thrown out, so that the inner wall of the metal bellows can be drier.

[0062] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0063] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
