Description
Technical Field
[0001] The present application relates to the technical field of pipeline laser cutting, and in particular to a highly efficient and precise rotary cutting machine. Background Art
[0002] Pipes usually need to be cut into lengths of corresponding specifications before they can be used. For cutting metal pipes, laser cutting is the most commonly used method in the industry. This technology uses the energy released when the laser beam hits the surface of the pipe wall to melt and evaporate the metal. The laser beam is focused on a very small area through lenses and reflectors. The high concentration of energy can quickly heat the area locally and evaporate the metal material. In addition, because the energy is very concentrated, only a small amount of heat is transferred to other parts of the steel, causing little or no deformation.
[0003] In actual pipe cutting applications, the pipe on the cutting machine will move toward the laser cutting machine, and at the same time, the pipe will rotate under the action of the robotic arm. When the pipe is transported to the laser cutting machine, the pipe will continue to move in a certain direction while rotating during laser cutting, resulting in tilted and uneven cuts. If the pipe stops moving while being cut, it will affect the processing efficiency of pipe cutting. Summary of the invention

[0046] It should be noted that by driving the third servo motor 903 to drive the third power gear 805 to rotate, the third power gear 805 drives the sliding plate 802 and the installation frame 4 to slide along the length direction of the guide rail 804 under the cooperation effect of the rack 804. The third servo motor 903 drives the third power gear 805 to rotate forward and reverse, so that the installation frame 4 can move back and forth along the guide rail 803.
[0047] Furthermore, the reciprocating translation mechanism 8 allows the shell 2 and the pipe 1 to move forward at the same speed, and further stabilizes the shell 2 through the synchronous clamping mechanism 7, allowing the two to be relatively still, and then cuts the pipe 1 through the surrounding cutting mechanism 6, making the cutting surface neat and smooth.

[0049] The implementation principle of the embodiment of the present application is as follows: during the cutting process of the pipe 1, the pipe 1 will continue to move along the direction of the laser generating device 604. In order to prevent the pipe 1 from having to stop running during cutting and to make the cut surface of the pipe 1 smooth, when the pre-cut section of the pipe 1 passes through the rotary cutting machine of the present application, the rotary cutting machine will move synchronously along the transportation direction of the pipe 1 under the action of the reciprocating translation mechanism 8, and the moving speed of the rotary cutting machine is the same as the speed of the pipe 1. At the same time, the synchronous clamping mechanism 7 in the rotary cutting machine clamps the pipe 1, so that the rotary cutting machine and the pipe 1 remain relatively stable, and further keep the two relatively still. Finally, the pipe 1 is cut by the surrounding cutting mechanism 6. At this time, the cut surface of the pipe 1 will be highly neat and smooth, and during the cutting process of the pipe 1, the pipe 1 does not need to stop running to ensure the quality of the cut surface.
