Description

Technical Field

[0001] This utility model relates to the technical field of pressing equipment, specifically to pipe bending pressing equipment. Background Technology

[0002] A pipe bending pressure tester is a specialized device used to pressure test pipe bends, checking their strength by applying pressure to the inside of the bend to see if it can withstand the pressure without cracking, deforming, or other damage. This ensures the safety and reliability of the bend in actual use. For example, in pipeline systems in industries such as petroleum, chemical, and natural gas, pipe bends need to withstand high pressures, and the pressure tester can perform quality checks on them.

[0003] Current pressure testing equipment typically blocks one end of the bend and pumps air into the other end to test its pressure. However, the relative positions of the two ends of different bend models vary, which makes pressure testing difficult. Therefore, a new type of bend pressure testing equipment is needed to solve these problems in order to ensure the smooth conduct of pressure testing. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that current pressure testing equipment generally blocks one end of the bend and pumps air into the other end to achieve the purpose of pressure testing. However, the relative positions of the two ends of different models of bends are different, which makes pressure testing difficult. This utility model provides a pressure testing equipment.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A pressing machine includes: a placement chamber, a lifting plate slidably inserted into the inner wall of the placement chamber, a plurality of bent pipes provided on one side of the lifting plate, and a limiting unit and a lifting unit. The limiting unit is used to limit the position of the plurality of bent pipes on one side of the lifting plate, and the lifting unit is used to control the sliding of the lifting plate on the inner wall of the placement chamber. The inner wall of one end of several of the bends is slidably connected with plugs, and the system also includes an adjustment unit and an air supply unit. The adjustment unit is used to adjust the position of the several plugs on one side of the lifting plate, and the air supply unit is used to inject air into the interior of the several bends respectively.

[0006] Furthermore, the placement chamber includes a main chamber body, the bottom of the main chamber body is provided with a liquid outlet, the liquid outlet is provided with a valve, the surface of the main chamber body is provided with a groove, and a transparent plate is fixedly inserted into the inner wall of the groove.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] The pipe bending pressure testing equipment provided in this embodiment is mainly used to solve the problem that current pressure testing equipment typically blocks one end of the pipe and pumps air into the other end to achieve the purpose of pressure testing. However, the relative positions of the two ends of different types of pipe bends vary, which brings difficulties to the pressure testing. The following technical solution is provided, which will be combined with... Figures 1-5 Please provide a detailed explanation: The pipe bending and pressing machine includes: a placement chamber 1 with a lifting plate 2 slidably inserted into its inner wall; and several bent pipes 3 arranged on one side of the lifting plate 2. During use, the user controls the lifting plate 2 to slide along the inner wall of the placement chamber 1 via a lifting unit 5, thereby raising and lowering the several bent pipes 3, which are restricted to one side of the lifting plate 2 by a limiting unit 4. Because several plugs 6 are arranged on one side of the lifting plate 2, during use, the user can supply air to the inside of the bent pipes 3 via an air supply unit 8 while simultaneously controlling the position of the plugs 6 via an adjustment unit 7, allowing the plugs 6 to slide and insert into the other end of the bent pipes 3 respectively. Finally, the lifting plate 2 is retracted into the placement chamber 1 via the lifting unit 5, and water is injected into the placement chamber 1, thereby achieving the pressing of several bent pipes. The pressure test of the bent pipe 3 is performed. The main components of the placement chamber 1 are: a main chamber body 11 with a liquid outlet 12 at the bottom. During use, the user can control the opening state of the liquid outlet 12 by controlling the valve 13 of the liquid outlet 12, thereby achieving the purpose of liquid drainage. Because a transparent plate 15 is fixedly inserted into the inner wall of the slot 14 on the surface of the main chamber body 11, the user can see the condition of the bent pipe 3 inside the main chamber body 11 (whether there are air bubbles) through the transparent plate 15. The main components of the limiting unit 4 are: several fixing clips 41 fixedly installed on the surface of the lifting plate 2. During use, the user slides the bent pipe 3 into the inner wall of the fixing clip while the bottom of the bent pipe 3 is against the surface of the lifting plate 2. Rotating several adjusting threaded rods 43, each threadedly inserted into the surface of several fixed clamps 41, causes several clamping plates 42, each rotatably sleeved on the surface of several adjusting threaded rods 43, to slide on the inner wall of several fixed frames. This causes the clamping plates 42 to fit against the surfaces of several bent pipes 3, thus limiting the position of the bent pipes 3 on one side of the lifting plate 2. The main components of the lifting unit 5 are: a first hydraulic rod 51 and an insert 53, both fixedly mounted on the surface of the lifting plate 2 at one end. A hollow pipe 52 is slidably sleeved on the surface of the insert 53. In use, the user controls the extension and retraction of the hydraulic rod, fixedly mounted on the surface of the main chamber 11 at the other end, via a controller 54 fixedly mounted on the surface of the main chamber 11, thereby raising and lowering the lifting plate 2. During this process, because the other end of the empty tube 52 is fixedly installed on the surface of the main compartment 11, the insertion tube 53 will slide synchronously on the inner wall of the empty tube 52, thereby ensuring the stability of the lifting plate 2 during the lifting process. The main components of the adjustment unit 7 are: several second hydraulic rods 71, each set on one side of the lifting plate 2. At the same time, one end of each of the second hydraulic rods 71 ​​is fixedly installed on one end of each of the plugs 6. Therefore, in use, the user drives the second hydraulic rods 71 ​​to move along the width of the lifting plate 2 through the drive unit 72, which in turn moves the plugs 6 along the width of the lifting plate 2. Finally, the controller 54 controls the extension and retraction of the second hydraulic rods 71 ​​to further adjust the position of the plugs 6.This design allows several plugs 6 to be precisely inserted into one end of several bends 3 (this configuration ensures that even if the bends 3 are of different models and have different relative positions at both ends, the user can still seal one end of the bend 3 by adjusting the position of the plugs 6). The main components of the air supply unit 8 are: several air pumps 81, each fixedly mounted on the surface of the lifting plate 2, with T-shaped pipes 82 fixedly connected to the air outlet of each air pump 81. In use, the user first aligns one end of each bend 3 with one of the T-shaped pipes 82, then controls the air pumps 81 to draw air, which is discharged through the outlet into the interior of the T-shaped pipes 82 and then into the interior of the bends 3, thus injecting air into the bends 3.

[0018] By sliding a lifting plate 2 into the inner wall of the placement chamber 1, the user first controls the lifting plate 2 to slide on the inner wall of the placement chamber 1 through the lifting unit 5, so that the lifting plate 2 slides out from the inside of the placement chamber 1. Then, the limiting unit 4 restricts several bends 3 to one side of the lifting plate 2. The adjusting unit 7 controls the position of several plugs 6, so that several plugs 6 are accurately inserted into one end of several bends 3. Finally, the lifting unit 5 controls the lifting plate 2 to retract into the interior of the placement chamber 1. Water is added to the inner wall of the placement chamber 1, and air is introduced into the other end of several bends 3 through the air supply unit 8. The pressure of the bends 3 can be detected by judging whether there are air bubbles leaking on the surface of several bends 3.

[0019] By using a pressurizing machine, a slot 14 is opened on the surface of the main chamber 11, and a transparent plate 15 is fixedly inserted into the inner wall of the slot 14. This allows the user to see the inside of the main chamber 11 through the transparent plate 15, thus making a clearer judgment on whether there are air bubbles leaking from the surface of the bent pipe 3.

[0020] like Figure 5 As shown, in some embodiments, the main components of the drive unit 72 are: several fixed protrusions 723 all disposed on the surface of the lifting plate 2, several through slots 721 opened on the surface of the lifting plate 2, and drive blocks 724 fixedly installed on the surface of several second hydraulic rods 71. Since the surfaces of several drive blocks 724 are slidably inserted into the inner walls of several through slots 721, and several drive threaded rods 722 are rotatably inserted into the surfaces of several fixed protrusions 723, when in use, the user can rotate several drive threaded rods 722 to drive several drive blocks 724, which are respectively threaded onto the surfaces of several drive threaded rods 722, to slide on the inner walls of several through slots 721, thereby adjusting the position of several second hydraulic rods 71 ​​along the width of the lifting plate 2.

[0021] The working process of this utility model is as follows: First, the user needs to control the extension and retraction of the first hydraulic rod 51 through the controller 54, so that the lifting plate 2 can slide out from the inside of the main chamber 11. Then, the surfaces of several bent tubes 3 are all in contact with the surface of the lifting plate 2, so that one end of each tube is fitted onto the surface of several T-shaped tubes 82. Finally, by rotating several adjusting threaded rods 43, several clamping plates 42 can be driven to fit against the surface of several bent tubes 3, thereby limiting the position of several bent tubes 3 on one side of the lifting plate 2. Secondly, the user needs to rotate the drive threaded rod 722, which will cause several drive blocks 724 to slide on the inner walls of several through slots 721 respectively, further realizing the movement of several second hydraulic rods 71 ​​along one end of the width of the lifting plate 2. Then, the controller 54 controls the extension and retraction of several second hydraulic rods 71, which can realize the adjustment of several plugs 6 at any position on one side of the lifting plate 2, so that several plugs 6 slide into one end of several bends 3 respectively. Finally, the controller 54 controls the extension and retraction of the first hydraulic rod 51, which drives the lifting plate 2 to retract the main chamber 11, fills the main chamber 11 with water, and controls several air pumps 81 to supply air to the inside of several bends 3 through the controller 54, which can realize the test of the pressure resistance of several bends 3.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
