DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0015] See attached Figure 1-3 A device for cutting a corrugated pipe to a fixed length comprises a pneumatic scissors 2 mounted on a workbench 1, a fixed length mechanism 3 is arranged on one side of the pneumatic scissors 2, the fixed length mechanism 3 comprises a scale 31 and a mounting seat 32, a movable positioning piece 34 is arranged on the mounting seat 32, support heads 4 are fixed on both sides of the cutting opening of the pneumatic scissors 2, a guide groove 8 is provided on the workbench 1, and a movable pushing head 5 is installed on the workbench 1. Through this arrangement, the existing manual cutting method is changed, and the positioning is more accurate through the fixed length mechanism 3, and the traditional method of cutting requires manual holding of the corrugated pipe, which has certain risks, such as Figure 3 As shown, in this solution, the bellows is moved in the guide groove 8. When the cutting point of the bellows is moved to the pneumatic scissors 2, it is only necessary to push the pushing head 5. This will enable the cutting point of the bellows to be pushed to the pneumatic scissors 2 with the support of the supporting heads 4 on both sides, thereby making the operation safer.

[0016] Specifically, a movable seat 33 is slidably mounted on the mounting seat 32, a positioning piece 34 is fixed on one side of the movable seat 33, and a measuring piece 35 is fixed on the other side. The positioning piece 34 and the measuring piece 35 are located on the same horizontal line. A plurality of equally spaced thread grooves 36 are provided on the mounting seat 32, and a bolt 37 is provided on the positioning piece 34. Figure 2 As shown, when the movable seat 33 moves on the mounting seat 32, the measuring piece 35 can observe the real-time length on the scale 31, thereby determining the required position of the positioning piece 34, and the distance from the positioning piece 34 to the cutting opening of the pneumatic scissors 2 is the distance that needs to be cut on the corrugated tube.

[0017] It is also necessary to say that, in the present embodiment, a groove 7 is provided in the guide groove 8, the bottom of the groove 7 is connected to a collecting box 6, the groove 7 and the cutting opening of the pneumatic scissors 2 are located on the same horizontal line, and the pushing head 5 is movably installed on the workbench 1 on the side of the guide groove 8, so that the corrugated tube residues cut off by the pneumatic scissors 2 will fall into the groove 7 and then be discharged into the collecting box 6 for collection.

[0018] During the specific operation, the bellows is placed on the guide groove 8 for movement, and the moving seat 33 is moved, and the cutting length is determined by aligning the measuring piece 35 with the scale on the scale 31. When the length is determined, the moving seat 33 is fixed by the bolt 37 threadedly installed in the threaded groove 36. At this time, the bellows is cut by pushing the pushing head 5 to make the bellows contact with the two supporting heads 4, and the bellows to be cut is pushed to the pneumatic scissors 2 by the pushing head 5, and then the pneumatic scissors 2 are started for cutting. Finally, the cut bellows residue will fall into the groove 7, and then be discharged into the collection box 6 for collection.
