However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0031] like Figure 1-6As shown, this utility model provides an automatic PE pipe end cutting device, including a base plate 1, a fixing frame 2 fixedly installed on the surface of the base plate 1, a hydraulic rod 3 fixedly installed inside the fixing frame 2, a cutter 4 fixedly installed at the output end of the hydraulic rod 3, a rectangular groove 5 opened on the surface of the base plate 1, two support plates 6 rotatably connected to the inner wall of the rectangular groove 5, two top plates 8 slidably connected inside the base plate 1, a push plate 7 fixedly installed on the surface of the top plate 8, an auxiliary hole 9 opened on the surface of the base plate 1, a mounting frame 11 slidably connected to the inner wall of the auxiliary hole 9, a lifting cylinder 10 threadedly connected to the surface of the mounting frame 11, and the cross-section of the mounting frame 11 is "T" shaped. The aforementioned components achieve the following effects: They can limit the movement of the PE pipe during the cutting process, preventing it from rolling and effectively avoiding the skewing caused by rolling during traditional PE pipe cutting, thus improving cutting accuracy. Wear-resistant pads 25 are fixedly installed on the surfaces of both push plates 7. The cross-section of the push plate 7 is a right-angled trapezoid. The wear-resistant pads 25 assist the push plate 7 in pressing against the support plate 6. Two balance frames 13 are fixedly installed on the surfaces of both push plates 7. Wheels 12 are rotatably connected to the surfaces of the balance frames 13, and the surfaces of the wheels 12 abut against the rectangular groove 5. The push plates 7 can slide with the assistance of the wheels 12 and the balance frames 13. Four fixing blocks 17 are fixedly installed on the inner wall of the rectangular groove 5. A rotating frame 16 is rotatably connected to the surface of the fixing blocks 17. A spring 15 is fixedly installed on the surface of the rotating frame 16. A rotating block 14 is fixedly installed at the end of the spring 15 away from the rotating frame 16. The surface of the rotating block 14 is fixedly connected to the support plate 6, and the spring 15 pulls against the support plate 6. The base plate 1 has a groove 19 on its surface. Two extrusion plates 21 are fixedly installed on the inner wall of the groove 19. A clamping plate 26 is slidably connected to the inner wall of the groove 19. A connecting frame 23 is fixedly installed on the surface of the clamping plate 26. Bolts 24 are threadedly connected to the inside of the connecting frame 23. The surface of the bolts 24 abuts against the two extrusion plates 21. The cross-section of the connecting frame 23 is "L". A baffle 20 is fixedly installed on the surface of the connecting frame 23. The baffle 20 can block the PE pipe when cutting the PE pipe end, making it easier for the operator to cut the PE pipe end. A scale 18 is fixedly installed on the surface of the base plate 1. The scale 18 has evenly distributed scale lines on its surface. The scale 18 can help the operator judge the length of the PE pipe end to be cut. A brush 22 is fixedly installed on the surface of the clamping plate 26. The surface of the brush 22 is slidably connected to the inner wall of the groove 19. When the clamping plate 26 slides, it drives the brush 22 to slide. During the sliding process, the brush 22 removes debris from the inner wall of the groove 19.
[0032] The overall working principle is as follows: When it is necessary to cut the PE pipe end, the two mounting brackets 11 slide towards each other. As the mounting brackets 11 slide, the top plate 8 slides, and as the top plate 8 slides, the push plate 7 slides. The push plate 7 slides on the auxiliary frame of the wheel 12 and the balance frame 13. As the push plate 7 slides, the support plate 6 rotates. After the support plate 6 rotates to the required angle, the mounting brackets 11 stop sliding. Then, the lifting cylinder 10 is rotated. The lifting cylinder 10 moves downward with the help of the screw. After the lifting cylinder 10 moves a certain distance, the surface of the lifting cylinder 10 presses against the bottom plate 1. At this time, the mounting brackets 11 are fixed, and the push plate 7 is also fixed. The push plate 7 can support the support plate 6 after it has rotated a certain angle. At this time, the PE pipe can be placed on the two support plates 6. The support plates 6 can restrict the rolling of the PE pipe. At this time, the PE pipe end can be cut.
