Description

Technical Field

[0001] The present invention relates to the technical field of snake bone tube cutting and processing, in particular to a cutting device for snake bone tube production and a process thereof. Background Art

[0002] The snake tube is a special pipe structure consisting of multiple interconnected, retractable pipe segments. Each segment is similar to a bone joint and is connected together by a hinge, allowing the entire pipe to bend and retract freely like a snake's body.

[0003] During the processing of snake-bone tubes, most of the tube sections are obtained by laser cutting, and then assembled to obtain snake-bone tubes. During the laser cutting process, the high-energy-density laser beam heats the tube, causing the surface temperature of the tube to rise until it vaporizes at the position where the laser beam is irradiated, thereby forming an incision on the tube to obtain a tube section of the desired shape.

[0004] Currently, in the laser cutting process of pipes, the pipes are generally placed on a cutting table and then cut. After the cutting is completed, the cut pipe section is removed and a new pipe is placed on it to continue cutting. The whole process is not coherent enough, which wastes processing time. In addition, the smoke and dust generated during the laser cutting process will have a certain impact on the workers. Therefore, we propose a cutting device and process for snake bone pipe production. Summary of the Invention

[0063] The present invention also provides a cutting process for producing a snake bone tube, comprising the following steps:

[0064] Step 1: Insert the pipe into the annular pipe and the pipe ring in sequence until one end enters the three-jaw chuck, fix one end of the pipe with the three-jaw chuck, and then hold the handle to rotate. The rotation of the handle drives the worm to rotate, and the rotation of the worm drives the meshing worm gear ring to rotate. The rotation of the worm gear ring drives the rotating ring to rotate clockwise, and the arc groove guides the chuck shaft so that the rotation of the rotating ring drives multiple sliders to move at the same time, so that multiple movable blocks can be moved toward the pipe at the same time until multiple wheels fit the outer wall of the pipe. Then the slide moves to drive the three-jaw chuck to move, so that the pipe moves until its to-be-cut position is aligned with the laser cutting assembly.

[0065] Step 2: While the laser cutting assembly is working, the servo motor is also working. The laser cutting assembly cuts the pipe into sections as the snake-bone pipe.

The rotation of the first reversing gear drives the second reversing gear to rotate. The rotation of the second reversing gear drives the connecting shaft to rotate. The rotation of the connecting shaft drives the fan blades to rotate, thereby generating negative pressure inside the slot. Then, through the connection of the connecting pipe and the annular pipe, multiple suction heads absorb the smoke and dust generated when the laser cutting component is working into the annular pipe and enter the drawer through the suction head. At this time, the solid particles in the smoke and dust will block the filter mesh, and the odor in the smoke and dust will absorb the filter element. At the same time, the rotation of the connecting shaft drives the turntable to rotate. When the turntable rotates, the piston blocks inside it will move toward each other under the action of centrifugal force, thereby squeezing the first spring and the hydraulic oil, so that the square piston can move upward from the connecting hole until the connecting hole is inserted into the square hole. Through the restriction of the connecting hole by the square hole, the rotation of the turntable can drive the rotating rod to rotate. The rotation of the rotating rod drives the scraper to rotate. The scraper can scrape the solid particles filtered on the filter mesh and move them to prevent the solid particles from clogging the filter mesh.

[0067] The present invention discloses a cutting device and process for producing snake bone tubes, which have the following beneficial effects:

[0068] The cutting device and process for producing snake-bone tubes can continuously push a long tube toward the laser cutting assembly for laser cutting through the setting of a tube pushing mechanism, and the cut tube segments can be removed by the feeding mechanism for collection, thereby reducing the manual operation process and making the cutting process more coherent, with less manual intervention, thereby improving the efficiency of the laser cutting process. At the same time, through the cooperation of the smoke removal mechanism, the smoke and dust generated during the cutting process can be quickly absorbed to avoid affecting the workers and improve the safety of the laser cutting process.
