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.

[0039] Example 1

[0040] like Figures 1-7 As shown;

[0041] The pipe bending and pressing machine includes a fixed frame 10, a water tank 11 disposed inside the fixed frame 10, and a pipe fitting 12 disposed above the water tank 11. It also includes an adjustment assembly 20 disposed on one side of the fixed frame 10. The adjustment assembly 20 includes a connecting frame 22, a lifting cylinder 23, a mounting frame 24, a first rotating component 25, a mounting plate 26, and a support frame 27. The connecting frame 22 is welded and fixed to one side of the fixed frame 10. The lifting cylinder 23 is installed inside the connecting frame 22. The telescopic shaft of the lifting cylinder 23 is rotatably connected to the mounting frame 24 through the support frame 27. The mounting frame 24 is rotatably connected to the fixed frame 10 through the first rotating component 25. The mounting plate 26 is fixedly disposed on the upper surface of the mounting frame 24 and at one end away from the support frame 27.

[0042] It also includes a detection component 30 disposed on the upper surface of the mounting plate 26 and cooperating with the adjustment component 20. The detection component 30 includes a clamping cylinder 31, a push rod 32, a plug 33, a fixing clamp 34, a connecting cylinder 35, and an inflation end 36. The clamping cylinder 31 and the connecting cylinder 35 are symmetrically mounted on the upper surface of the mounting plate 26 and are located near the end of the first rotating member 25. The push rod 32 is fixedly connected to the telescopic end of the clamping cylinder 31. The plug 33 is fixedly disposed on the end face of the push rod 32. The fixing clamp 34 is fixedly disposed on the upper surface of the mounting plate 26 and is located away from the end face of the clamping cylinder 31. The inflation end 36 is mounted on the telescopic shaft of the connecting cylinder 35. The pipe 12 is located on the upper surface of the mounting plate 26 and is fixedly connected to the mounting plate 26 by the fixing clamp 34.

[0043] In this implementation scheme: the pipe fitting 12 is placed on the upper surface of the mounting plate 26, and the bend of the pipe fitting 12 is clamped and fixed by the fixing clamp 34. The clamping cylinder 31 drives the push rod 32 to extend towards the bend of the pipe fitting 12, and cooperates with the plug 33 to seal one end of the pipe fitting 12. The connecting cylinder 35 drives the inflation end 36 to extend towards the other end of the pipe fitting 12 and connects. The pipe fitting 12 is fixed to the upper surface of the pipe fitting 12 by embedding, which makes it more secure during pressure testing and easier to install. After fixing, the lifting cylinder 23 is activated, and its telescopic shaft extends in cooperation with the support frame 27, so that the mounting plate 26 on the mounting frame 24 is at the first Rotating component 25 rotates at the pivot point, causing the bend of pipe fitting 12 to be submerged in the water tank 11. Air is injected into the pipe fitting 12 through an external air source in conjunction with the air inlet 36. Due to the sealing effect of the fitting 13, the pipe fitting 12 is sealed. During continuous inflation, if bubbles appear near the bend of pipe fitting 12, it indicates that the bend of pipe fitting 12 is damaged. Otherwise, the product is qualified. The operation is simple and quick to check whether there is a potential leakage at the bend of pipe fitting 12, ensuring the quality of the produced products. The equipment adopts a semi-submerged pressure testing method, which meets the pressure testing requirements while reducing the water immersion area, thus protecting the pipe fitting 12.

[0044] In an optional embodiment, the detection component 30 further includes auxiliary brackets 37 and elastic posts 38. The two auxiliary brackets 37 are symmetrically fixed on the upper surface of the mounting plate 26 and on the side close to the push rod 32, and the elastic posts 38 are fixed at the middle position of the fixing clamp 34.

[0045] In this embodiment: the rod of the pipe fitting 12 can be fixed to the upper surface of the mounting plate 26 by two auxiliary brackets 37, ensuring the firmness of the pipe fitting 12 on the upper surface of the mounting plate 26, which is convenient for subsequent rotation detection. The elastic column 38 is a rubber block, which gives the fixing clamp 34 good elasticity, so that the two fixing clamps 34 can firmly hold the pipe fitting 12.

[0046] In an optional embodiment, the inflation end 36 and the two auxiliary clamping seats 37 are located on the same horizontal line, and the fixing clamp 34 is located on the vertical line between the clamping cylinder 31 and the connecting cylinder 35.

[0047] The clamping cylinder 31, push rod 32, plug 33, fixing clamp 34, two auxiliary clamps 37, inflation end 36 and connecting cylinder 35 form a U-shaped structure.

[0048] In this embodiment: the rod of the pipe fitting 12 can be firmly fixed by two auxiliary brackets 37, and the bend of the pipe fitting 12 can be firmly fixed by the fixing clamp 34. The U-shaped structure formed facilitates the fixing of the U-shaped bend, forming an embedded structure that is convenient and secure.

[0049] In an optional embodiment, a fixing component 40 disposed within the fixing clamp 34 is also included;

[0050] The fixing assembly 40 includes a fixing plate 41, a connecting piece 42, a sliding member 43, an elastic piece 44, a base 46, and a slide block 47. The fixing plate 41 is fixedly disposed at the internal notch of the fixing clamp 34. The sliding member 43 is slidably connected inside the notch. The connecting piece 42 is fixedly connected between the fixing plate 41 and the sliding member 43. The elastic piece 44 is fixedly connected between the fixing plate 41 and the sliding member 43 and is located above the connecting piece 42. The base 46 is fixedly disposed on the bottom surface of the sliding member 43. The slide block 47 is fixedly connected to the bottom surface of the base 46. A groove adapted to the slide block 47 is provided in the notch.

[0051] In this embodiment: when the bent part of the pipe fitting 12 is inserted into the notch of the fixing clamp 34, the pipe fitting 12 can be locked between the fixing plate 41, the connecting piece 42 and the sliding member 43. With the help of the fixing component 40 at the top, a firm fixation of the pipe fitting 12 is formed. In addition, the elastic piece 44 increases the friction between the pipe fitting 12 and the elastic piece 44, which further ensures the stability of the installation. The sliding member 43 slides in the groove with the base 46 and the slide block 47, so that the sliding member 43 is movable, so that pipe fittings 12 of different diameters can be fixed in the notch, thus expanding the fixation range of the fixing clamp 34.

[0052] It should be noted that in this embodiment, both the connecting piece 42 and the elastic piece 44 are made of sheet rubber with good elasticity, which facilitates the sliding of the sliding member 43 and makes it convenient to adjust the surrounding space of the fixing plate 41, the connecting piece 42 and the sliding member 43. The elasticity of the elastic piece 44 is superior to that of the connecting piece 42.

[0053] In an optional embodiment, both the fixing plate 41 and the sliding member 43 are trapezoidal strip structures, and the connecting piece 42 is an inwardly concave arc structure.

[0054] In this embodiment, the cooperation of the three structures mentioned above, as well as the cooperation of the three structures at the top, facilitates the formation of a robust clamp structure, making it easy to securely fix the pipe fitting 12 to the inside of the clamp structure.

[0055] In an optional embodiment, the fixing component 40 further includes two locking plates 45, which are symmetrically arranged within the notch and located outside the fixing plate 41.

[0056] In this embodiment, the material of the clamping plate 45 is the same as that of the connecting piece 42. The two clamping plates 45 can block the notch to a certain extent and play a certain auxiliary fixing role.

[0057] In an optional embodiment, the fixing component 40 further includes a connector 48, the two ends of which are respectively connected to the sides of the base 46 of the fixing plate 41 and the slider 43 that are close to each other.

[0058] In this embodiment, the connector 48 is formed by a hollow cylinder with a connecting rod slidably connected inside. A connecting spring is fixedly connected between the inside of the cylinder and the connecting rod, so that the connecting rod slides inside the cylinder. The cooperation of the three gives the sliding member 43 the elasticity to move closer to the fixed plate 41, which is beneficial to improve the clamping force between the two and optimize the clamping of the pipe 12.

[0059] In an optional embodiment, an auxiliary detection component 50 is also included, which is disposed on the upper surface of the fixed plate 41 and the slider 43;

[0060] The auxiliary detection component 50 includes a connecting strip 51, a thin sheet 52, and a vibration sensor 53. The connecting strip 51 is fixedly embedded in one side of the fixed plate 41 and the sliding member 43 that are close to each other. The vibration sensor 53 is fixedly disposed inside the connecting strip 51. The thin sheet 52 is fixedly disposed on the surface of the connecting strip 51 and located outside the vibration sensor 53.

[0061] In this embodiment: the vibration sensor 53 is fixed to the inner wall of the fixing plate 41 or the sliding member 43 by the connecting strip 51. The vibration sensor 53 can detect whether the thin sheet 52 vibrates. The vibration at this point is caused by the emergence of bubbles, which helps to detect whether the bending point is damaged.

[0062] It should be noted that in this embodiment, the upper surface of the elastic sheet 44 is also provided with an auxiliary detection component 50, and multiple vibration sensors 53 are arranged at intervals to facilitate comprehensive detection of whether the bending point is damaged.

[0063] In an optional embodiment, a clamping assembly 60 disposed inside the inflation end 36 is also included;

[0064] The clamping assembly 60 includes an electric push rod 61, a clamping member 62, a silicone layer 64, and a light sensor 65. The electric push rod 61 is fixedly installed in the groove on the end face of the inflation end 36, and the telescopic end of the electric push rod 61 penetrates the inner wall of the inflation end 36. The clamping member 62 is fixedly installed at the telescopic end of the electric push rod 61. The silicone layer 64 is bonded and fixed to the inner wall of the clamping member 62. The light sensor 65 is fixedly installed inside the silicone layer 64.

[0065] In this embodiment: when the tube 12 is inserted into the inflatable end 36, the electric push rod 61 is activated to drive the clamping member 62 to approach the outer wall of the tube 12 until the silicone layer 64 contacts the outer wall of the tube 12. The photosensitive sensor 65 can determine whether the silicone layer 64 is in close contact with the outer wall of the tube 12, thereby improving the sealing of the connection between the inflatable end 36 and the tube 12.

[0066] In an optional embodiment, the clamping member 62 is formed by connecting the end of the fixed rod to the clamping plate, and the clamping assembly 60 further includes a spring 63. Two springs 63 are symmetrically arranged on both sides of the clamping member 62, and the two ends of the springs 63 are respectively connected to the outer side wall of the fixed rod and the end face of the clamping plate.

[0067] In this embodiment, the clamping member 62 is given a certain elasticity by the spring 63, so that the clamping member 62 can generate a certain degree of inner or outer contour, which is conducive to adapting to pipes 12 with different outer diameters.

[0068] It should be noted that all electrical components in this application are electrically connected to the controller, and the detection data from the light sensor 65 and the vibration sensor 53 can be fed back to the controller's display screen for easy and intuitive viewing.

[0069] Working principle and usage process of the present invention: Move the fixing frame 10 to the usage location. First, manually place the pipe fitting 12 on the upper surface of the mounting plate 26, and the bent portion of the pipe fitting 12 is tightly clamped and fixed by the fixing clamp 34. The elastic column 38 is a rubber block, endowing the fixing clamp 34 with good elasticity, enabling the two fixing clamps 34 to firmly clamp the pipe fitting 12. When the bent portion of the pipe fitting 12 is inserted into the notch of the fixing clamp 34, the pipe fitting 12 can be clamped between the fixing plate 41, the connecting piece 42, and the sliding member 43, facilitating the firm fixation of the rod body of the pipe fitting 12 through the two auxiliary clamping seats 37. The bent portion of the pipe fitting 12 can be firmly fixed by the fixing clamp 34, and the formed U-shaped structure is convenient for fixing the U-shaped elbow pipe, forming an embedded type, facilitating firm fixation. The two clamping plates 45 achieve a certain degree of sealing of the notch, playing a certain auxiliary fixing role, and cooperating with the fixing component 40 at the top to form a firm fixation of the pipe fitting 12. And cooperating with the elastic piece 44 to increase the friction force with the pipe fitting 12, ensuring the stability of the installation again. Moreover, the sliding member 43 cooperates with the base 46 and the sliding seat 47 to slide in the chute, making the sliding member 43 mobile, so that pipe fittings 12 with different diameters can be fixed in the notch, expanding the fixable range of the fixing clamp 34. The clamping cylinder 31 drives the push rod 32 to extend towards the bent portion of the pipe fitting 12, and cooperates with the plug 33 to block one end of the pipe fitting 12. The connecting cylinder 35 drives the inflation end 36 to extend towards the other end of the pipe fitting 12 and connect. When the pipe fitting 12 is inserted into the interior of the inflation end 36, start the electric push rod 61 to drive the clamping member 62 to approach the outer wall of the pipe fitting 12 until the silicone layer 64 contacts the outer wall of the pipe fitting 12. The optical sensor 65 can be used to judge whether the silicone layer 64 is in close contact with the outer wall of the pipe fitting 12, improving the sealing performance of the connection between the inflation end 36 and the pipe fitting 12. The spring 63 endows the clamping member 62 with a certain elasticity, enabling the clamping member 62 to generate a certain degree of inner profile or outer profile, facilitating the adaptation to pipe fittings 12 with different outer diameters. The pipe fitting 12 is fixed to the upper surface of the pipe fitting 12 by an embedded type, being more reliable during pressure testing and convenient for loading and clamping. After fixation, start the lifting cylinder 23 on the connecting frame 22, and its telescopic shaft cooperates with the support frame 27 to extend, causing the mounting plate 26 on the mounting frame 24 to rotate with the first rotating member 25 as the rotation point, making the bent portion of the pipe fitting 12 immerse in the water in the water tank 11. Inflate the interior of the pipe fitting 12 through an external air inflation source in cooperation with the inflation end 36. Due to the cooperation with 13, the pipe fitting 12 is sealed. During continuous inflation, if bubbles appear near the bent portion of the pipe fitting 12, it indicates that there is a breakage at the bent portion of the pipe fitting 12, otherwise the product is qualified. The operation is simple and fast to check whether there is a leakage hidden danger at the bent portion of the pipe fitting 12, ensuring the quality of the produced products. Fix the vibration sensor 53 to the inner side wall of the fixing plate 41 or the sliding member 43 through the connecting strip 51. The vibration sensor 53 can be used to detect whether vibration occurs at the thin plate 52. The vibration here is the vibration generated by the bubbles emerging, assisting in detecting whether there is a breakage at the bent portion. The equipment adopts a semi-submerged water pressure testing method, satisfying the pressure testing while reducing the water contact surface.This helps protect fitting 12, after which fitting 12 can be removed.
