[0023] like Figure 1-5 As shown, multiple tooth plates 4 are evenly divided into two groups, and the two groups of tooth plates 4 are movably embedded in the outer surfaces of the two moving blocks 6. When the clamping block 10 is clamped on the gear 9, the tooth plates 4 can position the gear 9 to prevent the gear 9 from continuing to rotate.
[0024] like Figure 1-5 As shown, multiple gears 9 are meshed and connected to the outer surfaces of multiple tooth plates 4, multiple fixed plates 12 are evenly divided into two groups, two groups of fixed plates 12 are fixedly connected to the outer surfaces of two moving blocks 6, and the fixed plates 12 can position the spring 11, providing a good working environment for the spring 11.

[0026] Working principle: This equipment is a PE pipe rounding machine. When in use, first connect the two positioning blocks 20 on the upper cavity 21 with the telescopic rod 18 through bolts 19, and place the lower cavity 22 on the workbench 1, and the inner diameters of the upper cavity 21 and the lower cavity 22 are equal to the outer diameter of the PE pipe to be rounded. Then place the PE pipe to be rounded in the lower cavity 22, and make the PE pipe to be rounded fit with the two fixing blocks 2, and then manually press the operating rod 13 respectively, so that the operating rod 13 drives the two fixing blocks 2 to move. The two clamping blocks 10 make a circular motion with the two fixed rods 8 as the center, and the two clamping blocks 10 no longer limit the two gears 9, and when the clamping blocks 10 rotate, they will squeeze the springs 11 on the two fixed plates 12, so that the two springs 11 obtain elastic potential energy, and then manually push the moving block 6, so that the moving block 6 drives the slide bar 5 to move on the inner surface of the slide groove 3, and the two gears 9 make a circular motion with the two fixed rods 7 as the center on the outer surface of the two toothed plates 4, so that the moving block 6 and the whole circle of PE pipe The two springs 11 release the elastic potential energy, causing the two clamping blocks 10 to move in the opposite direction and get stuck on the outer surfaces of the two gears 9, limiting the rotation of the two gears 9, and then meshing with the upper tooth plate 4 and the gear 9 to form a self-locking function, which is convenient for the two moving blocks 6 to position the two ends of the PE pipes of different models and sizes, so that the pipes will not slide during the rounding process, thereby improving the accuracy of the size and ensuring the matching degree of the final pipe specifications. Then, the hydraulic cylinder 17 is started, and the fixed rod three 15 and the fixed plate two 16 on the support block 14 can support the hydraulic cylinder 17. The hydraulic cylinder 17 moves the telescopic rod 18 downward, and the telescopic rod 18 drives the upper cavity 21 to move downward through the bolts 19 so that the two positioning blocks 20 drive the upper cavity 21 to move downward. Finally, the upper cavity 21 and the lower cavity 22 squeeze the PE pipe to be rounded, so that the PE pipe to be rounded returns to the state of a ring, and the PE pipe to be rounded is rounded by the hydraulic cylinder 17, which reduces the labor intensity, saves labor, and improves the efficiency of rounding.
