Detailed ways

As shown in Figures 1-2, a pipe splitting and flattening machine includes a base plate 1 and a first conveying component, a splitting component, a flattening component and a second conveying component installed on the base plate 1 from right to left.

The splitting assembly includes two symmetrically arranged adjustable bearing seats 2. A rotating roller 3 is installed between the two adjustable bearing seats 2. The rotating roller 3 is driven by a driving assembly, and the driving assembly includes an installation unit. Reducer and motor on the adjustable bearing seat 2. A first chopping knife 4 is installed on the rotating roller 3. A support rod 5 matching the first chopping knife 4 is provided below the first chopping knife 4. The support rod 5 is connected through a mounting bracket 6. On the adjustable bearing seat 2, a groove is provided on the top of the support rod 5, and a second cleaver 7 is rotatably connected in the groove. The top of the second cleaver 7 is connected to the first cleaver 7. The bottom of the riving knife 4 is misaligned.

Both the first conveying assembly and the second conveying assembly include a conveying frame 8 connected to the base plate 1 , and a plurality of conveying rollers 9 arranged at equal intervals are installed on the conveying frame 8 .

A guide and positioning assembly is installed on one end of the first conveying assembly close to the splitting assembly. The guiding and positioning assembly includes two vertical plates 10 installed on the conveying frame 8. The vertical plates 10 are provided with There are several guide holes arranged at equal intervals. Guide rods 11 are inserted into the guide holes. A guide roller 12 is installed on one end of the guide rod 11. The other end of the guide rod 11 is fixed on the connecting plate 13. A threaded hole is provided in the middle of the connecting plate 13, and a threaded rod 14 is threadedly connected in the threaded hole. One end of the threaded rod 14 is rotationally connected to the vertical plate 10 through a bearing, and the other end is connected to a runner. 15.

The distance between the two guide rollers 12 in the same row on the splitting assembly becomes larger, so that the steel pipe can be in the middle position of the conveyor frame 8 and prevent the end of the steel pipe from pressing against the support rod. 5 on.

The end of the first conveying assembly away from the splitting assembly is provided with a pushing assembly. The pushing assembly includes a hydraulic cylinder 16 and a push plate 17.
