Technical Field

[0001] The invention relates to the technical field of pipeline groove cutting, in particular to a multi-angle composite pipeline groove cutting device. Background Art

[0002] The pipe beveling machine is a special tool for chamfering the front face of the pipe before welding.

[0045] Furthermore, a liquid storage tank 9 is fixedly connected to the inner wall of the bottom of the cutting frame 5, and a pump body 33 is installed on the outer wall of the bottom end of the liquid storage tank 9. An output pipe 1 is plugged into an output end of one side of the pump body 33, and an output pipe 2 is plugged into an output end of the other side of the pump body 33.

When rotating shaft 1 31 and rotating shaft 2 32 rotate with auxiliary transmission wheel 1 17 and auxiliary transmission wheel 2 27 to adjust the cutting angle, the valve stem of the rotary regulating valve 36 will be synchronously twisted, so that more coolant is sprayed when the cutting structure angle is large, and the spraying of coolant is correspondingly reduced when the cutting angle is small.

[0046] Working principle: When performing groove cutting of composite pipes, the two pipes that need to be grooved are placed on both sides of the pipe groove cutting frame 4 respectively, and are clamped and fixed by two three-jaw chucks 3. The hydraulic rod is started to make the two three-jaw chucks 3 approach the cutting frame 5 on the mounting frame 7 at the same time. The groove cutting tool 1 25 on the left side of the cutting frame 5 has a larger spacing and is located on the outside of the pipe to be cut. The groove cutting tool 2 26 on the right side of the cutting frame 5 has a smaller spacing and is located on the inside of the pipe to be cut. The angle of the cutting structure is adjusted according to the cutting requirements, and the motor 3 29 is started. The motor 3 29 drives the two gears 4 28 to rotate in opposite directions through meshing, thereby driving the two main drive wheels 30 to rotate in opposite directions. The main drive wheel 30 cooperates with the auxiliary drive wheel 1 17 and the auxiliary drive wheel 2 27 through the transmission belt to drive the rotating shaft 1 31 and the rotating shaft 2 32 inside the bracket 10 and the bracket 2 24 on both sides of the pipe to rotate. The two bevel cutting tools 1 25 and the groove cutting tool 2 26 rotate to the required groove cutting angle, and the motor 1 6 is started to rotate the gear 14, and the meshing rack 15 drives the cutting frame 5 to rotate, so as to start the groove cutting of the two pipes that need to be connected synchronously. The motor 2 19 drives the bidirectional screw 18 to rotate, thereby driving the two slide bars 12 to approach, and drives the bidirectional screw 2 22 to rotate through the meshing gear 20 and the gear 3 21, and the two slide bars 2 23 separate, so that the two groove cutting tools 1 25 on the left side of the cutting frame 5 approach to cut the groove of the pipe from the outside, and the two groove cutting tools 2 26 on the right side of the cutting frame 5 separate to cut the groove of the pipe from the inside. After the synchronous cutting is completed, the cut pipes can be directly removed to complete the connection. The cutting groove cutting tool structures on both sides of the cutting frame 5 are connected together through a linkage structure, and the angle and distance adjustment are synchronized, which is suitable for the groove cutting of composite pipes with different requirements.

[0047] During the pipe cutting process, it is necessary to spray coolant for cooling treatment. A liquid storage tank 9 is installed in the cutting frame 5. The liquid storage tank 9 is provided with a liquid inlet pipe, a liquid outlet pipe, an air inlet and an air outlet. An air compressor is also installed to provide compressed air. A safety valve is provided on the liquid storage tank 9 to prevent damage to the system caused by excessive high or low air pressure. During the cutting process, the pump body 33 transports the coolant to both sides, and the coolant is sprayed out through the water pipe 11 and the water pipe 2 34 respectively in cooperation with the nozzle 35. The nozzle 35 is adapted to the position of the groove cutting tool 1 25 and the groove cutting tool 2 26. Spraying the coolant can cool the pipe cutting. The cutting is cooled. The larger the cutting angle of the composite pipe, the larger the contact area between the groove cutting tool 1 25 or the groove cutting tool 2 26 and the pipe, and the higher the demand for cooling. The valve stem of the rotary regulating valve 36 on the water pipe 1 11 and the water pipe 2 34 is connected to the rotating shaft 1 31 and the rotating shaft 2 32. When the rotating shaft 1 31 and the rotating shaft 2 32 rotate with the auxiliary transmission wheel 1 17 and the auxiliary transmission wheel 2 27 to adjust the cutting angle, the valve stem of the rotary regulating valve 36 will be turned synchronously, so that more coolant is sprayed when the cutting structure angle is large, and the spraying of coolant is correspondingly reduced when the cutting angle is small.

[0048] The nozzle 35 rotates together with the groove cutting tool structure and sprays at the position just cut to improve the cooling effect. The liquid storage tank 9 is installed in the cutting frame 5 and rotates with the cutting frame 5. The coolant in the liquid storage tank 9 is in a slow motion state to ensure stable performance and prevent precipitation from affecting the cooling effect. A pressure sensor is installed in the liquid storage tank 9 to monitor the air pressure changes in real time. The control system adjusts the opening of the air inlet and the air outlet on the liquid storage tank 9 according to the feedback from the pressure sensor to maintain the set air pressure and compensate for the water pressure fluctuation caused by the rotation of the liquid storage tank 9, so that the pumping process of the pump body 33 is smoother.

Matters not covered in the present invention belong to the common knowledge of those skilled in the art.
