PE pipe is widely used in water supply, gas transmission, fire protection system and other fields. Its pressure resistance directly affects the safety of the project. Pressure test can identify whether there are cracks, aging or connection defects in the pipeline, and prevent leakage or pipe burst accidents caused by abnormal pressure.

10. A detection method for a PE pipe pressure detection device, characterized in that: The following steps are involved: S1. When performing the PE pipe pressure test, the corresponding PE pipe can be inserted into the PE pipe feeding slot in the vertical direction. When the dual-axis servo motor is started, the dual-axis servo motor can drive the second output shaft to rotate, and the second output shaft can drive the second gear to rotate, so that the second gear drives the second rack meshing with it to move horizontally, and the second rack drives the mobile feeding rack to move, so that the anti-slip sliding block on the outer side of the mobile feeding rack slides in the anti-slip sliding slot, and the mobile feeding rack drives the PE pipe to move at the same time when it moves; S2. The user places the PE pipe vertically between the corresponding surfaces of the two PE pipe clamping connection sleeves, and then starts the telescopic clamping mechanism to drive the PE pipe clamping connection sleeve to move, so that the PE pipe clamping connection sleeve can clamp the PE pipe tightly; S3, start the dual-axis servo motor, and let the output shaft on one side of the dual-axis servo motor drive the ball screw to rotate. At this time, the ball nut on the outer side of the ball screw can move in the horizontal direction, and the ball nut drives the movable mounting frame to move in the horizontal direction at the same time, so that the movable mounting frame drives the guide movable seat to move, and the slider at the bottom of the guide movable seat slides in the guide fixed seat. When the guide movable seat moves, it drives the first rack to move, and the first rack drives the first gear meshing with it to rotate, and the first gear drives the fixed sleeve to flip through the transmission shaft; S4. The telescopic clamping mechanism and the PE pipe clamping connection sleeve can drive the clamped PE pipe to flip at the same time. The position of the flipped PE pipe is aligned with the pressure test position of the PE pipe pressure test pressing mechanism. The PE pipe pressure test pressing mechanism can be started to make the output shaft of the PE pipe pressure test pressing mechanism perform vertical extrusion, thereby performing the PE pipe pressure test. S5. After the PE pipe pressure test is completed, the dual-axis servo motor can be started again, and the corresponding output shaft of the dual-axis servo motor drives the ball screw to rotate, and the ball nut drives the movable mounting frame to move horizontally, and the movable mounting frame drives the guide movable seat to move, and the guide movable seat drives the first rack to move when it moves, and the first rack drives the first gear meshing with it to rotate, and the first gear drives the fixed sleeve to flip and reset through the transmission shaft. After the PE pipe pressure test is completed, it can be reset; The two output shafts of the S6 dual-axis servo motor drive the ball screw and the second gear to rotate respectively, which can synchronously complete the feeding and flipping auxiliary pressure resistance test. It can realize the full process operation of PE pipe feeding, PE pipe loading, PE pipe clamping, PE pipe flipping, pressure testing and unloading at the same workstation, and can continuously perform PE pipe pressure resistance test.
