Technical Field

[0001] This utility model belongs to the technical field of pipeline mold testing equipment, and in particular relates to an expansion simulator that is easy to disassemble. Background Technology

[0002] The expansion simulator can perform quality inspection and performance evaluation on expansion molds. By simulating the expansion process of the pipe to be expanded, the simulator can detect the key performance indicators of the expansion mold under different pressures and deformation degrees, and promptly identify quality problems in the mold under test. At the same time, by changing different expansion molds for expansion testing, the actual working status of the expansion mold can be effectively detected, which facilitates the improvement of the expansion mold. However, the existing expansion molds require manual rotation for installation and disassembly, which is relatively laborious, resulting in inconvenient disassembly and assembly and low testing efficiency of the expansion simulator. Therefore, this utility model proposes a new solution to the above-mentioned technical problems. Utility Model Content

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1 to 13 As shown, this utility model embodiment provides a conveniently disassembled diameter expansion simulator, comprising:

[0035] The device comprises a base 11 for a diameter expansion simulator, a main adjustment structure 12 for adjusting the diameter expansion mold 3, and a rotating structure for connecting the diameter expansion mold 3. The main adjustment structure 12 is connected to the base 11. The rotating structure is connected to the main adjustment structure 12 and to the other side of the base 11. In this embodiment, the connection between the diameter expansion mold 3 and the rotating structure is detachable, mainly through threaded connectors. To facilitate installation or disassembly, the diameter expansion mold 3 is usually manually rotated to a position for easy disassembly. In this embodiment, the rotating structure drives the main adjustment structure 12 to rotate synchronously during rotation. This allows the expansion mold 3 to rotate automatically instead of manually, saving manpower during disassembly and improving the ease of installation and disassembly. The rotating structure includes a power structure 131 and a rotating connector 132. The rotating connector 132 is connected to the base 11 of the expansion simulator and is used to connect the expansion mold 3.

The power structure 131 is connected to the rotating connector 132 and drives the rotating connector 132 to rotate and install or disassemble the expansion mold 3, thus changing the rotation of the expansion mold 3 from manual to automatic, improving testing efficiency.

[0036] Specifically, the rotating structure also includes a rotating gear 133, which is connected to the rotating connector 132 and drives the rotating connector 132 to rotate through the power structure 131 connected to the rotating gear 133. This enables the rapid installation and disassembly of the expansion mold 3, reducing the time and labor intensity of manual operation and improving testing efficiency.

[0037] In this embodiment of the utility model, the rotating gear 133 and the rotating connector 132 are fastened by a threaded connection, which effectively enhances the stability of the connection. At the same time, the rotation accuracy of the rotating connector 132 is improved by gear transmission, so that the diameter expansion mold 3 can be rotated to a position that is more convenient to disassemble, thereby improving the installation and disassembly efficiency.

[0038] Furthermore, the rotating connector 132 is provided with a rotating connector body 1321 and a rotating connector limiting member 1322.

The rotating gear limiting end 13214 is provided with a plurality of rotating gear fastening holes corresponding one-to-one with the rotating gear limiting holes, so that the rotating gear 133 is mounted on the rotating gear mounting part 13213 through the rotating gear mounting hole 1331, and connected to the rotating gear limiting hole and the rotating gear through a first threaded connector. The rotating gear 133 is fastened to the rotating connector body 1321 in the wheel fastening hole. Under the premise of ensuring that the rotating connector body 1321 is subjected to uniform force, the rotating gear 133 is prevented from shaking during transmission, thereby improving the transmission accuracy of the rotating gear 133.

[0040] Furthermore, the rotating connector body 1321 is also provided with an adjustment structure mounting cavity 13211 and a connecting limiter mounting position 13212. The connecting limiter mounting position 13212 is connected to the adjustment structure mounting cavity 13211. The main adjustment structure 12 adjusts the expansion mold 3 through the adjustment structure mounting cavity 13211. The rotating connecting limiter 1322 is connected to the connecting limiter mounting position 13212 to limit the main adjustment structure 12, so as to ensure that the rotating connector body 1321 can drive the main adjustment structure 12 to rotate synchronously for installation and disassembly, reducing the time and labor intensity of manual operation and improving the convenience of installation and disassembly of the expansion simulator.

[0041] Furthermore, the power structure 131 is a drive motor, and the output end of the drive motor is provided with a power output gear 1311. The power output gear 1311 is connected to the rotating gear 133 to drive the rotating connecting body 1321 to rotate. The drive motor can provide a stable speed and torque to ensure that the rotating connecting body 1321 rotates smoothly and accurately, thereby realizing the smooth installation and disassembly of the expansion mold 3 and improving the operating efficiency and reliability of the entire device. In this embodiment of the utility model, the drive motor is one of a stepper motor, a DC motor, or a servo motor.

In this embodiment of the present invention, the pull rod shaft 122 is fastened to the main adjustment cylinder 121 through the telescopic connector 123, and when lifting... While ensuring convenient installation or disassembly of the telescopic connector 123, the maximum displacement of the tie rod shaft 122 is limited by the telescopic connector 123 to ensure that the tie rod shaft 122 will not damage the expansion mold 3, thereby enhancing the safety of the expansion simulator during use. This design can accurately convert hydraulic power into mechanical adjustment action, enabling the main adjusting cylinder 121 to provide a stable push-pull force, ensuring that the tie rod shaft 122 moves smoothly back and forth within the adjusting structure mounting cavity 13211 to adjust the expansion or repositioning of the expansion mold 3.

The telescopic connector upper cover groove and the telescopic connector lower cover groove form a main adjustment structure mounting cavity. One end of the main adjustment cylinder piston rod 1212 and the pull rod shaft 122 are respectively connected and secured in the main adjustment structure mounting cavity. Under the premise of ensuring that the main adjustment cylinder piston rod 1212 can push or pull the pull rod shaft 122 to move back and forth, the telescopic connector 123 will not drive the pull rod shaft 122 to rotate synchronously during the rotation of the rotating connector body 1321, thereby extending the service life of the main adjustment cylinder piston rod 1212.

[0045] Furthermore, the pull rod shaft 122 is provided with a pull rod shaft limiting part 1221, and the rotatable connecting limiting member 1322 abuts against the pull rod shaft limiting part 1221 to limit the pull rod shaft 122.
