Description

Technical Field

[0001] This utility model relates to the technical field of pipe fitting testing equipment, and in particular to a flexible bending testing machine. Background Technology

[0002] Pipe fittings are a general term for components in a piping system that serve functions such as connection, control, direction change, flow diversion, sealing, and support. During the production and processing of pipe fittings, a bending testing machine is needed to perform multiple bending tests on the pipe fittings in order to test their flexibility and facilitate subsequent operations.

[0003] A pipe flexibility testing machine, disclosed in announcement number CN210665351U, belongs to the field of pipe testing equipment. It includes a base, comprising a bottom plate and a back plate vertically mounted on the bottom plate. Two bending support blocks are symmetrically arranged on the back plate. A fixing device is located on the bottom plate between the two bending support blocks. The fixing device includes an inner fixing mechanism and an outer fixing mechanism, located on the inner and outer sides of the pipe to be tested, respectively. The inner fixing mechanism abuts against the inner wall of the pipe, and the outer fixing mechanism abuts against the outer wall of the pipe. This invention has the advantage of improving the clamping effect on the pipe to be tested.

[0004] However, the existing pipe flexibility testing machine still has the following defects in use: When using the above-mentioned existing technology, the pipe to be tested is placed vertically on the base plate and positioned between the inner and outer fixing mechanisms to fix it, which facilitates the flexibility test. However, in actual use, since the pipe is fixed, it is inconvenient to rotate and adjust it. As a result, the flexibility test cannot be performed on different surfaces of the pipe, which leads to its low practicality and large limitations. Utility Model Content

[0005] The purpose of this invention is to provide a flexibility bending test machine to solve the problem mentioned in the background art that the existing flexibility bending test machines do not have rotation adjustment during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flexibility bending test machine, including a worktable, a protective frame, and a hydraulic cylinder. The top of the worktable is welded with a protective frame, and the top of the protective frame is fixedly connected to the hydraulic cylinder by bolts.

[0007] A movable platform is slidably mounted on the top of the workbench, and support plates are fixed on both sides of the top of the movable platform. An adjustment plate is mounted on one side of each of the two support plates, and an adjustment rod is mounted inside each adjustment plate. Two movable blocks are sleeved on the outside of each adjustment rod. A clamping plate is fixed on one side of each movable block. An auxiliary shaft is mounted on one side of one adjustment plate, and a steering mechanism is mounted on one side of the other adjustment plate. A guide groove is opened on one side of each support plate, and a guide block is slidably mounted inside each guide groove. An adjustment mechanism is mounted on one side of the movable platform, and a slider is fixed on the other side of the movable platform. A sliding rod passes through the inside of the slider. A bending plate is mounted on the bottom of the hydraulic cylinder.

[0008] When using the flexibility bending testing machine of this technical solution, the adjustment mechanism facilitates the rotation and adjustment of the pipe fitting under the action of the adjustment plate, guide groove and guide block, thereby facilitating flexibility bending tests on different surfaces of the pipe fitting and improving the accuracy of the test.

[0009] Furthermore, the steering mechanism includes a fixed motor, which is disposed on one side of the support plate. A fixed shaft is fixed to one side of the fixed motor, and a fixed plate is welded to one end of the fixed shaft.

[0010] Furthermore, the fixed plate has a circular cross-section, the outer edge of the fixed plate slides against the inner wall of the support plate, and one side of the fixed plate is fixedly connected to an adjustment plate.

[0011] Furthermore, the adjustment mechanism includes an adjustment motor, which is located at the top of the worktable. An adjustment shaft is fixed to one side of the adjustment motor, and an adjustment block is sleeved on the outside of the adjustment shaft.

[0012] Furthermore, the slider slides on the slide rod, and the movable stage is slidably connected to the worktable via the slider and the slide rod.

[0013] Furthermore, the guide blocks are provided in two sets, with two guide blocks in each set, and the guide blocks in each set are symmetrically distributed. One side of each set of guide blocks is fixedly connected to the adjustment plate.

[0014] Furthermore, the clamping plates are provided in two sets, with two clamping plates in each set, and a protective pad is attached to one side of each set of clamping plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the flexibility bending test machine not only has a rotation adjustment function, but also a position adjustment function;

[0016] By starting the fixed motor, the fixed plate rotates under the action of the fixed shaft, and an adjusting plate rotates under the action of the guide block and guide groove. At the same time, another adjusting plate rotates under the action of the auxiliary shaft, thereby causing the clamped pipe to rotate synchronously. The above operation facilitates the flexible bending test on different surfaces of the pipe, thereby improving the accuracy of the test.

[0017] By starting the adjusting motor, the fixed plate moves horizontally under the action of the fixed shaft, and the moving table moves synchronously under the action of the slider and the sliding rod. At the same time, the clamped pipe moves synchronously. The above operation makes it easy to conduct flexibility bending tests on different positions of the pipe, thereby improving its practicality.

[0025] 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. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Please see Figures 1-5 An embodiment of this utility model provides a flexible bending testing machine, including a workbench 1, a protective frame 5, and a hydraulic cylinder 7. The top of the workbench 1 is welded with a protective frame 5, and the top of the protective frame 5 is fixedly connected to the hydraulic cylinder 7 by bolts. A movable platform 2 is slidably arranged on the top of the workbench 1, and support plates 3 are fixed on both sides of the top of the movable platform 2. An adjusting plate 9 is arranged on one side of each of the two support plates 3, and an adjusting rod 13 is arranged inside the adjusting plate 9. Two moving blocks 12 are sleeved on the outside of the adjusting rod 13, and a clamping plate 17 is fixed on one side of each moving block 12.

[0027] There are two sets of clamping plates 17, with two clamping plates 17 in each set, and a protective pad is attached to one side of each set of clamping plates 17.

[0028] Specifically, such as Figure 4 As shown, when in use, a protective pad is provided on one side of the clamping plate 17 to protect the pipe fitting when it is clamped and limited, thus avoiding scratches on the outer surface of the pipe fitting.

[0029] An auxiliary shaft 4 is provided on one side of one adjusting plate 9, and a directional adjustment mechanism 10 is provided on one side of the other adjusting plate 9;

[0030] The steering mechanism 10 includes a fixed motor 1001, which is disposed on one side of the support plate 3. A fixed shaft 1002 is fixed on one side of the fixed motor 1001, and a fixed plate 1003 is welded to one end of the fixed shaft 1002.

[0031] The fixed plate 1003 has a circular cross-section. The outer edge of the fixed plate 1003 slides against the inner wall of the support plate 3, and one side of the fixed plate 1003 is fixedly connected to an adjustment plate 9.

[0032] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, during use, the adjusting plate 9 makes selective movement by the fixed motor 1001 under the action of the fixed shaft 1002 and the fixed plate 1003, thereby making the pipe make synchronous rotational movement, which facilitates the flexible bending test on different surfaces of the pipe and improves its flexibility.

[0033] A guide groove 6 is provided on one side of the support plate 3, and a guide block 16 is slidably arranged inside the guide groove 6.

[0034] There are two sets of guide blocks 16, with two guide blocks 16 in each set, and each set of guide blocks 16 is symmetrically distributed. One side of each set of guide blocks 16 is fixedly connected to the adjusting plate 9.

[0035] Specifically, such as Figure 2 , Figure 3 As shown, during use, the guide block 16 slides inside the guide groove 6, thereby limiting the movement of the adjustment plate 9 and preventing it from shifting in position during movement, which in turn facilitates the subsequent flexibility bending test operation.

[0036] An adjustment mechanism 11 is provided on one side of the mobile station 2;

[0037] The adjustment mechanism 11 includes an adjustment motor 1101, which is located at the top of the workbench 1. An adjustment shaft 1102 is fixed on one side of the adjustment motor 1101, and an adjustment block 1103 is sleeved on the outside of the adjustment shaft 1102.

[0038] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, during use, by starting the adjusting motor 1101, the position of the moving table 2 can be easily adjusted under the action of the adjusting shaft 1102 and the adjusting block 1103, thereby facilitating the flexible bending test of the pipe at different positions and improving its practicality.

[0039] A slider 15 is fixed on the other side of the moving stage 2;

[0040] The slider 15 slides on the slide rod 14, and the moving stage 2 is slidably connected to the worktable 1 through the slider 15 and the slide rod 14;

[0041] Furthermore, a sliding rod 14 runs through the interior of the slider 15, and a bending plate 8 is provided at the bottom of the hydraulic cylinder 7;

[0042] Specifically, such as Figure 2 As shown, during use, the slider 15 slides on the slide bar 14, thereby limiting and guiding the moving platform 2, thus improving its stability during movement.

[0043] Working Principle: In use, when a flexible bending test is required on a pipe fitting, a section of the pipe fitting is selected and placed between two adjusting plates 9. The two adjusting rods 13 are moved horizontally relative to each other by rotating the knob slide rod 14, causing the two clamping plates 17 to move synchronously. This operation facilitates the clamping and limiting of the pipe fitting. Then, the bending plate 8 is lowered by activating the hydraulic cylinder 7 until one side of the bending plate 8 is in contact with the pipe fitting, at which point the flexible bending test is performed. After one side of the test is completed, the system is stabilized by activating the hydraulic cylinder 7. The fixed motor 1001 causes the fixed shaft 1002 to rotate, and the fixed shaft 1002 rotates simultaneously, causing the fixed plate 1003 to rotate synchronously, which in turn causes an adjusting plate 9 to rotate. This causes the guide block 16 to slide inside the guide groove 6, thereby limiting the movement of the adjusting plate 9. While the adjusting plate 9 is moving, the pipe fitting that is limited and clamped is rotated synchronously under the action of the protective frame 5 and the other adjusting plate 9. The above operation facilitates the flexible bending test on different surfaces of the pipe fitting, thereby improving the accuracy of the test.

[0044] Then, by starting the adjusting motor 1101, the adjusting shaft 1102 is rotated. While the adjusting shaft 1102 is rotating, the adjusting block 1103 moves horizontally, which in turn causes the moving stage 2 to move horizontally. This causes the slider 15 to slide on the slide rod 14. The slider 15 can limit the movement of the support plate 3 to prevent it from shifting position and affecting subsequent operations. On the other hand, it can also guide the moving stage 2 to improve its stability. While the moving stage 2 is moving, the two support plates 3 move synchronously, which facilitates the synchronous movement of the clamped pipe. The above operations facilitate the adjustment of the pipe's position, making it easy to conduct flexibility bending tests on different positions of the pipe, thereby improving its practicality.
