Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 to 14 Figures 1 to 14 , the present invention provides a technical solution: a metal tube laser cutting device, which includes a bottom fixing base 11. A cutting machine body 12 is fixedly arranged on the bottom fixing base 11. A cutting seat 13 and a base 14 are arranged on the cutting machine body 12. A laser head in the prior art is arranged between the cutting seat 13 and the base 14, and a corresponding cooling system is set for the operation of the laser head, such as a cooling system realized by circulating coolant. The laser head emits a laser beam for precise cutting. This is a common means of laser cutting equipment in the prior art and will not be elaborated here. A partition board 15 is arranged on the cutting machine body 12. A movable baffle 16 is rotatably arranged on the cutting machine body 12. The partition board 15 and the movable baffle 16 are locked by an electronic lock 17. A fixed square bottom plate 1 is arranged at the upper end of the cutting machine body 12. A fixed straight plate 7 is fixedly installed at the upper end of the fixed square bottom plate 1. An inclined driving member 2 is arranged on the fixed straight plate 7. A support bracket 3 is fixedly arranged on the inclined driving member 2. A cavity tube 9 is rotatably arranged on the support bracket 3. A power member 4 for driving the cavity tube 9 to rotate is arranged on the support bracket 3. A support plate controller 6 is fixedly arranged at one end of the cavity tube 9. Three support plates 8 are arranged on the support plate controller 6. The support plate controller 6 is used to drive the three support plates 8 to gather or spread synchronously. The support plate controller 6 and the support plates 8 are a numerically controlled robotic arm driving a manipulator in the prior art. An air drying and cleaning member 5 is arranged on the support bracket 3. The air drying and cleaning member 5 includes a pushing part 51, a gas collecting part 52 and a jetting part 53. By arranging the air drying and cleaning member 5, during the rotation and processing of the metal tube, through the cooperation of the pushing part 51 and the gas collecting part 52, the piston rod 521 continuously pushes the gas in the pushing air pipe 522 into the gas collecting airbag 526 for storage. After the processing is completed, by rotating the movable baffle 16, the rotating column 25 is separated from the movable baffle 16, and the metal tube tilts under the action of gravity. The tilted metal tube accelerates the sliding of the residual cutting residues on the outside and inside of the metal tube. Through the cooperation of the gas collecting part 52 and the jetting part 53, the electric control valve 5210 is controlled to open, so that the gas in the gas collecting airbag 526 is ejected from the outer nozzle 533 and the inner nozzle 536. Under the action of the air flow, the residual cutting residues inside and outside the tilted metal tube quickly fall, realizing the cleaning of the inside and outside of the metal tube. At the same time, under the action of the air flow, the air flow can be accelerated, realizing the cooling of the cut metal tube. By arranging the partition board 15 and the movable baffle 16, the cutting residues are prevented from flying out of the workbench. Through the cooperation of the movable baffle 16 and the inclined driving member 2, when the movable baffle 16 is opened, the metal tube can be automatically tilted. When the movable baffle 16 and the partition board 15 are in a locked state, the metal tube can be driven to be in a horizontal state, improving the convenience.

The support bracket 3 is fixedly installed on the rotating connecting column 27. The movable baffle 16 is disengaged from the rotating column 25. The metal pipe tilts under the action of gravity, drives the first gear 26 to rotate through the support bracket 3. The first gear 26 drives the moving toothed plate 22 and the moving block 21 to move and compress the buffer spring 23. The buffer spring 23 slows down the moving speed of the moving toothed plate 22, thereby realizing the automatic tilt of the metal pipe.

[0035] As Figure 10 and Figure 11 shown, the power member 4 includes a motor 41, a second gear 42, and a toothed ring 43. The motor 41 is fixedly installed on the support bracket 3. The second gear 42 is fixedly installed at the output end of the motor 41. The toothed ring 43 is fixedly installed on the cavity pipe 9. The second gear 42 meshes with the toothed ring 43. By starting the motor 41, the motor 41 drives the second gear 42 to rotate. The second gear 42 drives the toothed ring 43 to rotate. The toothed ring 43 drives the cavity pipe 9 to rotate.

[0036] As Figure 12 shown, the pushing part 51 includes a third gear 511, an eccentric rod 512, a rotating connecting plate 513, and a pushing column 514. The third gear 511 is rotatably connected to the support bracket 3. The toothed ring 43 meshes with the third gear 511. The eccentric rod 512 is fixedly connected to one side of the center of the third gear 511. One end of the eccentric rod 512 away from the third gear 511 is rotatably connected to the rotating connecting plate 513. One end of the rotating connecting plate 513 away from the eccentric rod 512 is hinged to the pushing column 514. During the rotation of the toothed ring 43, it drives the third gear 511 to rotate. The third gear 511 drives the eccentric rod 512 to rotate. The eccentric rod 512 drives the pushing column 514 to reciprocate through the rotating connecting plate 513.

[0037] As Figure 12As shown in the figure, the gas collecting part 52 includes a piston column 521, a pushing air pipe 522, an intake short pipe 523, a check valve I 524, a check valve II 525, a gas collecting airbag 526, a pressure relief valve 527, an air outlet connecting pipe 528, a rotary joint 529 and an electric control valve 5210. One end of the gas collecting airbag 526 is connected to the pushing air pipe 522, and the other end of the gas collecting airbag 526 is connected to the air outlet connecting pipe 528. A check valve II 525 is arranged on the pushing air pipe 522. A piston column 521 is slidably connected inside the pushing air pipe 522. The piston column 521 is fixedly connected to one end of the pushing column 514 away from the rotary connecting plate 513. An intake short pipe 523 is arranged on the pushing air pipe 522. A check valve I 524 is arranged on the intake short pipe 523. A pressure relief valve 527 is arranged on the gas collecting airbag 526. An electric control valve 5210 is arranged on the air outlet connecting pipe 528. One end of the air outlet connecting pipe 528 away from the gas collecting airbag 526 is fixedly installed with one end of the rotary joint 529, and the other end of the rotary joint 529 is fixedly installed with one end of the cavity pipe 9 close to the gas collecting airbag 526. When the piston column 521 moves to the left, the gas in the pushing air pipe 522 is pushed into the gas collecting airbag 526 for storage. When the piston column 521 moves to the right, a negative pressure is generated in the pushing air pipe 522, and the gas enters the pushing air pipe 522 from the intake short pipe 523. The piston column 521 continuously pushes the gas in the pushing air pipe 522 into the gas collecting airbag 526 for storage.

[0038] As Figure 9 , Figure 13 and Figure 14 shown in the figure, the jetting part 53 includes an L-shaped pipe 531, an annular pipe 532, an outer jetting pipe 533, a connecting hose 534, an arc-shaped air cavity 535, an inner jetting pipe 536 and a fixed cylinder 537. The L-shaped pipe 531 is connected to the cavity pipe 9. One end of the L-shaped pipe 531 away from the cavity pipe 9 is connected to the annular pipe 532. A plurality of outer jetting pipes 533 are connected to the annular pipe 532. The annular pipe 532 is fixedly installed on the support plate controller 6 through the fixed cylinder 537. A connecting hose 534 is connected to the annular pipe 532. One end of the connecting hose 534 away from the annular pipe 532 is connected to the arc-shaped air cavity 535. The arc-shaped air cavity 535 is fixedly connected to the support plate body 8. A plurality of inner jetting pipes 536 are connected to the arc-shaped air cavity 535. When the electric control valve 5210 is controlled to open, the gas in the gas collecting airbag 526 enters the cavity pipe 9 through the air outlet connecting pipe 528 and the rotary joint 529, and then enters the annular pipe 532 through the L-shaped pipe 531. The gas in the annular pipe 532 enters the outer jetting pipes 533 and the connecting hose 534. The gas is ejected from the outer jetting pipes 533 to blow off the cutting residues on the outer side of the metal pipe. The gas in the connecting hose 534 enters the arc-shaped air cavity 535 and is finally ejected from the inner jetting pipes 536 to blow off the cutting residues splashed inside the metal pipe.

[0039] By providing an air-drying and cleaning component 5, during the rotational processing of the metal pipe, through the cooperation of the pushing part 51 and the air-collecting part 52, the piston column 521 continuously pushes the gas in the pushing air pipe 522 into the air-collecting airbag 526 for storage. After the processing is completed, by rotating the movable baffle 16, the rotating column 25 is separated from the movable baffle 16, and the metal pipe tilts under the action of gravity. The tilted metal pipe accelerates the sliding of the residual cutting residues on the outside and inside of the metal pipe. Through the cooperation of the air-collecting part 52 and the air-jetting part 53, the electric control valve 5210 is controlled to open, so that the gas in the air-collecting airbag 526 is ejected from the outer spray pipe 533 and the inner spray pipe 536. Under the action of the air flow, the residual cutting residues inside and outside the tilted metal pipe quickly fall, realizing the cleaning of the inside and outside of the metal pipe. At the same time, under the action of the air flow, the air flow can be accelerated, realizing the cooling of the cut metal pipe. By providing a partition baffle 15 and a movable baffle 16, the cutting residues are prevented from flying out of the workbench. Through the cooperation of the movable baffle 16 and the tilt driving component 2, when the movable baffle 16 is opened, the metal pipe can be automatically tilted, and when the movable baffle 16 and the partition baffle 15 are in a locked state, the metal pipe can be driven to be in a horizontal state, improving the convenience.

[0040] In actual use, three support plate bodies 8 are inserted into the metal tube, and the support plate controller 6 drives the three support plate bodies 8 to quickly expand. The support plate controller 6 is a numerical control drive mechanism in the prior art, which is used to drive the three support plate bodies 8 to synchronously gather or expand, so as to fix the metal tube. The support plate body 8 drives the arc-shaped air cavity 535 to move, so that the inner spray pipe 536 is close to the inner wall of the metal tube. By starting the motor 41, the motor 41 drives the second gear 42 to rotate, the second gear 42 drives the toothed ring 43 to rotate, the toothed ring 43 drives the cavity tube 9 to rotate, the cavity tube 9 drives the support plate controller 6 and the support plate body 8 to rotate, and then realizes the rotation of the metal tube. The movement of the cutting seat 13 and the base 14 can drive the molybdenum wire to cut and groove the rotating metal tube. During the rotation of the toothed ring 43, it drives the third gear 511 to rotate, the third gear 511 drives the eccentric rod 512 to rotate, and the eccentric rod 512 drives the push column 514 to reciprocate through the rotating connecting plate 513, and then drives the piston column 521 to reciprocate in the push air pipe 522. When the piston column 521 moves to the left, it realizes pushing the gas in the push air pipe 522 into the gas collecting airbag 526 for storage. When the piston column 521 moves to the right, a negative pressure is generated in the push air pipe 522, and the gas enters the push air pipe 522 from the intake short pipe 523. The piston column 521 continuously pushes the gas in the push air pipe 522 into the gas collecting airbag 526 for storage. The setting of the pressure relief valve 527 avoids the too high air pressure of the gas collecting airbag 526, and the safety is improved. When the cutting is completed, there will be cutting residues remaining outside and inside the metal tube. Control the electronic lock 17 to open, rotate the movable baffle 16, and the movable baffle 16 is separated from the rotating column 25. The metal tube tilts under the action of gravity, drives the first gear 26 to rotate through the support bracket 3, the first gear 26 drives the moving toothed plate 22 and the moving block 21 to move and squeeze the buffer spring 23, and the buffer spring 23 slows down the moving speed of the moving toothed plate 22, and then realizes the automatic tilting of the metal tube. At the same time, control the electric control valve 5210 to open, and the gas in the gas collecting airbag 526 enters the cavity tube 9 through the air outlet connecting pipe 528 and the rotary joint 529, and then enters the annular tube 532 through the L-shaped tube 531. The gas in the annular tube 532 enters the outer spray pipe 533 and the connecting hose 534. The gas is ejected from the outer spray pipe 533 to blow off the cutting residues on the outside of the metal tube. The gas in the connecting hose 534 enters the arc-shaped air cavity 535 and finally is ejected from the inner spray pipe 536 to realize blowing off the cutting residues splashed inside the metal tube, and the convenience is improved.
