Description

Technical Field

[0001] The present application relates to the technical field of PE pipe cutting equipment, and in particular to a PE pipe cutting and curling removal device. Background Art

[0002] PE pipe (polyethylene) material is widely used in the field of municipal gas and water pipe manufacturing due to its high strength, corrosion resistance, and non-toxicity. PE pipes require cutting equipment to cut the pipes during production.

[0003] When existing curling cutting equipment is used to cut PE pipes, a person is required to carry the equipment and rotate it around the pipe. The cutting process is inconvenient and becomes more severe as the pipe diameter increases. In addition, the existing equipment uses a ratchet wrench and manual tightening equipment, which places high demands on the operator. It is more likely to cause discontinuous, uneven and incomplete cutting during cutting.

[0008] After the rolling gear ring cooperates with the pipe to be cut, it squeezes the pressure spring to store a certain amount of elastic potential energy. The pressure spring pushes the telescopic rod and the connecting rivet by releasing the elastic potential energy, so that the cutting tool is pressed against the outer surface of the PE pipe. When the rolling gear ring rotates, it drives the cutting module to rotate, and the cutting module drives the cutting tool to rotate and cut the PE pipe, so that the PE pipe can be cut evenly by the cutting equipment during cutting.

[0009] Preferably, the cutting module includes a cutting tool holder, a pressure spring, a telescopic rod, a connecting rivet and a cutting tool, the cutting tool holder is connected to the inner side of the rolling gear ring by screws, the pressure spring and the telescopic rod are arranged on the inner side of the cutting tool holder, the top of the pressure spring is welded to the top of the telescopic rod, and the cutting tool is connected to the telescopic rod by a connecting rivet.

[0010] Preferably, the cutting module comprises a cutting tool holder and a cutting blade, the cutting tool holder is fixedly connected to the rolling gear ring above by screws, and the cutting blade is arranged at the bottom of the cutting tool holder.

[0011] Preferably, both sides of the cutting blade are inclined surfaces, and an inclined notch is provided at the middle position of the inner side of the cutting blade.

[0012] When cutting the PE pipe, the rolling gear ring rotates to drive the cutting module to rotate. The cutting module drives the cutting blade to rotate to remove the curling edge on the outside of the PE pipe. The curling edge strip can be completely and evenly cut out for curling test, simplifying the process steps.

[0013] In summary, the present application includes at least one of the following beneficial effects:

[0014] 1. The PE pipe cutting and curling cutting device, the pressure spring pushes the telescopic rod and the connecting rivet through its own elastic force, so that the cutting tool is pressed against the outer surface of the PE pipe. When the rolling gear ring rotates, it drives the cutting module to rotate, and the cutting module drives the cutting tool to cut the PE pipe in a rotary manner, so that the PE pipe can be cut evenly by the cutting equipment during cutting, and it is not easy to cause uneven cutting of the PE pipe.

[0015] 2. The PE pipe cutting and curling removal device, when the PE pipe is cut, the rolling gear ring rotates to drive the cutting module to rotate, and the cutting module drives the cutting blade to rotate to remove the curling on the outside of the PE pipe.
