Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a device for comparing the force deformation of bellows. Background Technique

[0002] A bellows is a flexible pipe element with a corrugated shape. It consists of a series of alternating crests and troughs, which are arranged along the length of the pipe. The design of the bellows gives it high elasticity and scalability, enabling it to withstand axial, lateral or angular displacements while maintaining structural integrity. During the manufacturing process of bellows, strength testing equipment plays a crucial role. These precision testing tools can ensure that the bellows have the necessary mechanical properties and durability when facing expected service conditions.

[0003] After retrieval, a strength testing device for bellows processing disclosed in the utility model patent with the Chinese patent publication number CN216646119U includes a bottom plate. A support plate is fixedly connected to the rear side of the top of the bottom plate. The top of the support plate is fixedly connected with a cross plate, and a hydraulic push rod is fixedly connected to the top of the cross plate. Through the combined use of the bottom plate, support plate, cross plate, hydraulic push rod, extrusion block, pressure gauge, first clamping plate, drive box, protection box, motor, turntable, transmission shaft, first push rod, second push rod, first moving rod, first spring, second moving rod, second spring, second clamping plate, sliding sleeve and sliding rod, this utility model has the advantage of stable fixation, and solves the problem that the existing strength testing device for bellows processing has insufficiently stable clamping of bellows. During the pressure application process of the bellows, it is prone to shift, resulting in errors in the test data, and thus easily reducing the practicability of the bellows strength testing device.

[0004] However, although the above-mentioned strength testing device for bellows processing can effectively detect the strength of bellows, it has certain limitations. Specifically, this device can only detect the force deformation of bellows under a certain specific pressure each time. This means that in order to obtain comprehensive deformation data of the bellows under different pressures, the operator needs to conduct multiple independent tests, manually record the pressure data each time, and then compare and analyze these data. This process is not only time-consuming and laborious, but also lacks convenience and intuitiveness, restricting the testing efficiency and accuracy. Therefore, a device for comparing the force deformation of bellows is proposed to solve the above problems. Content of the Utility Model

This means that in order to obtain comprehensive deformation data of corrugated pipes under different pressures, the operator needs to conduct multiple independent detections, manually record the pressure data each time, and then compare and analyze these data. This process is not only time-consuming and laborious, but also lacks convenience and intuitiveness, restricting the detection efficiency and accuracy.

[0008] To achieve the above object, the utility model provides the following technical solution: A device for comparing the force deformation of corrugated pipes includes a bottom plate. A corrugated pipe clamping and fixing mechanism is arranged on the top of the bottom plate. A corrugated pipe body is arranged inside the corrugated pipe clamping and fixing mechanism.

[0011] Further, two fixing plates are arranged outside both of the two limit posts. First sliding grooves are formed on the opposite sides of both of the two limit posts. Two of the fixing plates are fixedly installed on the opposite sides of the two limit posts.

In this way, one of the threaded shafts stops rotating, and the pressure gauge and the pressing plate on the corresponding side also stop moving downward, thereby stopping the pressure applied to the corrugated pipe body. However, at this time, the other threaded shaft and the pressure gauge and the pressing plate on the corresponding side are not affected and still move downward to apply pressure to the corrugated pipe body. Therefore, the deformation data of the corrugated pipe body under different pressures can be obtained in a single test, greatly improving the detection efficiency and accuracy, and at the same time avoiding the time consumption and labor intensity brought by repeated tests.

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 , a corrugated pipe force and deformation comparison device in this embodiment includes a bottom plate 1. A corrugated pipe clamping and fixing mechanism 2 is arranged on the top of the bottom plate 1. A corrugated pipe body 3 is arranged inside the corrugated pipe clamping and fixing mechanism 2. A corrugated pipe force and deformation test mechanism 4 is arranged on the top of the bottom plate 1;

[0027] The corrugated pipe clamping and fixing mechanism 2 includes a limit post 201, a threaded rod 202, a fixing plate 203 and a limit base 204. Two limit posts 201 are fixedly installed on the top of the bottom plate 1. Threaded rods 202 are rotatably connected inside the two limit posts 201. Fixing plates 203 are arranged outside the two limit posts 201. Two limit bases 204 are fixedly installed on the top of the bottom plate 1;

[0028] The bellows force-deformation test mechanism 4 includes a mounting plate 401, a threaded shaft 402, a connection disk 403, a limit turntable 404, a limit insertion rod 405, a transmission disk 406, a transmission belt 407, a connection plate 408, a pressure gauge 409, a pressing plate 410, and a motor 411. A mounting plate 401 is fixedly installed at the top of the bottom plate 1. The threaded shaft 402 is rotatably connected inside the mounting plate 401. The connection disk 403 is fixedly installed at the top of the threaded shaft 402. The limit turntable 404 is fixedly installed on the inner top wall of the mounting plate 401. The limit insertion rod 405 is inserted outside the limit turntable 404. The transmission disk 406 is rotatably connected to the top of the mounting plate 401. The transmission belt 407 is movably installed outside the transmission disk 406. The connection plate 408 is threadedly connected to the outside of the threaded shaft 402. The pressure gauge 409 is fixedly installed at the bottom of the connection plate 408. The pressing plate 410 is fixedly installed at the bottom of the pressure gauge 409. The motor 411 is fixedly installed inside the mounting plate 401.

[0029] Specifically, when the two limit insertion rods 405 are accurately inserted into the insertion holes inside the two connection disks 403 and the two limit turntables 404 respectively, the motor 411 drives the two threaded shafts 402 to rotate through the coordinated operation of the limit turntable 404, the transmission disk 406, and the transmission belt 407. At this time, the pressure gauges 409 and the pressing plates 410 assembled at the bottoms of the two connection plates 408 act together and move downward synchronously, applying pressure to the bellows body 3 at the same time, which can ensure the accuracy of the detection results.

[0030] Specifically, when performing the force-deformation detection on the bellows body 3, one of the limit insertion rods 405 can be accurately inserted into the insertion holes inside one of the connection disks 403 and one of the limit turntables 404 first, so that one of the threaded shafts 402 rotates. The pressure gauge 409 and the pressing plate 410 assembled at the bottom of one group of connection plates 408 perform the force-deformation detection on one point of the bellows body 3 under one pressure condition. After the detection is complete, one of the limit insertion rods 405 inside one of the connection disks 403 and one of the limit turntables 404 is pulled out. Then, the other limit insertion rod 405 is accurately inserted into the insertion holes inside the other connection disk 403 and the other limit turntable 404, so that the other threaded shaft 402 rotates. The pressure gauge 409 and the pressing plate 410 assembled at the bottom of the other group of connection plates 408 perform the force-deformation detection on another point of the bellows body 3 under another pressure condition. Thus, comprehensive deformation data of the bellows body 3 under different pressures can be obtained in a single detection.

[0031] Specifically, by attaching the four fixing plates 203 to the inner top and bottom walls at the left and right ends of the corrugated pipe body 3 respectively, and rotating the threaded rod 202 to make the four fixing plates 203 fit more tightly with the inner top and bottom walls at the left and right ends of the corrugated pipe body 3, the fixing of the corrugated pipe body 3 is realized. This fixing method can effectively avoid the problem of unstable fixing caused by the deformation of the corrugated pipe body 3 during the fixing process of the corrugated pipe body 3.

[0032] In summary, for the corrugated pipe stress deformation comparison device, when the operator needs to obtain the comprehensive deformation data of the corrugated pipe body 3 under different pressures, only one of the connecting disks 403 and one of the limit insertion rods 405 inside the corresponding limit turntable 404 need to be pulled out. In this way, one of the threaded shafts 402 stops rotating, and the pressure gauge 409 and the pressing plate 410 on the corresponding side also stop moving downward, thus stopping the pressure applied to the corrugated pipe body 3. However, at this time, the other threaded shaft 402 and the pressure gauge 409 and the pressing plate 410 on the corresponding side are not affected and still move downward to apply pressure to the corrugated pipe body 3. Therefore, the deformation data of the corrugated pipe body 3 under different pressures can be obtained in a single test, greatly improving the detection efficiency and accuracy. At the same time, it avoids the time consumption and labor intensity brought by repeated tests, and solves the problem that the device can only detect the stress deformation of the corrugated pipe under a certain specific pressure each time. This means that in order to obtain the comprehensive deformation data of the corrugated pipe under different pressures, the operator needs to conduct multiple independent tests, manually record the pressure data each time, and then compare and analyze these data. This process is not only time-consuming and laborious, but also lacks convenience and intuitiveness, restricting the detection efficiency and accuracy.
