Description

Technical Field

[0002] The principle of plasma cutting machine is to use the high energy density and instantaneous high temperature of plasma to melt metal materials, thereby realizing cutting, welding and other processes. During the cutting process, the plasma gun generates arc discharge through the power supply, ionizes the gas atoms and forms plasma. The high energy density and instantaneous high temperature of plasma can melt the metal material instantly and form a high-speed airflow, thereby achieving the purpose of cutting the metal material. In the process of processing and cutting aluminum plates, a plasma cutting machine is needed.

[0026] like Figure 5 As shown, a fifth chute 42 inclined downward is provided on one side of the U-shaped frame 141, and the fifth chute 42 is connected to the fourth chute 38, and an angle is provided between the fifth chute 42 and the fourth chute 38, and the angle is greater than 120 degrees and less than 150 degrees, so that the fifth slider 39 can slide smoothly along the fifth chute 42 into the fourth chute 38. The connection between the fourth chute 38 and the fifth chute 42 is an arc transition, the fifth slider 39 is a rectangular parallelepiped structure, and the edges and corners of the fifth slider 39 that contact the arc transition at the connection between the fourth chute 38 and the fifth chute 42 when sliding are all arc-shaped, so that the fifth slider 39 can slide smoothly from the fourth chute 38 into the fifth chute 42.

[0027] Working principle: When in use, the aluminum plate is placed in the U-shaped frame 141, at which point one side of the aluminum plate abuts against the push plate 16, and the other side of the aluminum plate abuts against the baffle 17. The first motor 5 is started, and the output end of the first motor 5 drives the driving gear 7 to rotate, and the driving gear 7 engages with the driving rack 6 to drive the gantry 3 to move left and right. At the same time, the third motor 13 is started, and the output end of the third motor 13 drives the third threaded rod 12 to rotate, and the rotation of the third threaded rod 12 drives the connecting plate 8 to move, and the connecting plate 8 drives the plasma cutting body and the cutting nozzle 10 to move forward and backward, so that the cutting nozzle 10 moves in multiple directions to cut the aluminum plate, thereby meeting the need to cut the aluminum plate into various shapes.

[0028] After the aluminum plate is cut, the second motor 15 is started, and the output end of the second motor 15 drives the second threaded rod 32 to rotate, and the rotation of the second threaded rod 32 drives the second slider 33 to move rightward, and the second slider 33 drives the U-shaped frame 141 to move rightward, and the U-shaped frame 141 drives the second mounting plate 28 to move, and the second mounting plate 28 drives the second rotating shaft 29 to move, and the second rotating shaft 29 drives the third gear 30 and the fourth gear 34 to move at the same time, and the third gear 30 is meshed with the third rack 27 for self-rotation, and the third gear 30 drives the fourth gear 34 to rotate through the second rotating shaft 29, and the fourth gear 34 drives the fifth gear 35 to rotate, and the fifth gear 35 drives the fourth rack 36 to move rightward, and the fourth rack 36 drives the fourth slider 37 to move rightward along the fourth slide groove 38, and the fourth slider 37 drives the fifth slider 39 to slide along the fourth slide groove 38 through the hinge rod 40, and the fifth slider 39 drives the baffle 17 to move rightward through the connecting rod 41, thereby opening the baffle 17 to prevent the baffle 17 from subsequently hindering the aluminum plate from moving rightward. When the fifth slider 39 enters the fifth slide groove 42 along the fourth slide groove 38, the fifth slider 39 rotates in cooperation with the fifth slide groove 42, so that the fifth slider 39 drives the baffle 17 to rotate downward through the connecting rod 41 to prevent the baffle 17 from hindering the unloading of the aluminum plate.

[0029] When the fifth slider 39 abuts against the bottom wall of the fifth slide slot 42, the third gear 30 is disengaged from the third rack 27. At this time, the second gear 25 is just engaged with the second rack 26, and then the U-shaped frame 141 continues to move rightward, the U-shaped frame 141 drives the first mounting plate 23 to move, the first mounting plate 23 drives the first shaft 24 to move, the first rotation drives the first gear 22 and the second gear 25 to move at the same time, the second gear 25 drives the first shaft 24 to rotate under the action of the engagement with the second rack 26, the first shaft 24 drives the first gear 22 to rotate, the first gear 22 drives the first rack 21 to move rightward, the first rack 21 drives the push plate 16 to move rightward, the push plate 16 drives the cut aluminum plate to move rightward, so that the aluminum plate is pushed out of the U-shaped frame 141, so that the operator can take out the aluminum plate. When the push plate 16 moves rightward to the maximum limit, the second gear 25 and the second rack 26 continue to maintain the meshing state.

[0030] When loading the aluminum plate, the operator can place one end of the aluminum plate on the placement plate 142, and at the same time place the aluminum plate on the top of the baffle 17, so that the baffle 17 supports the aluminum plate, thereby saving manpower, and then push the aluminum plate to slide to the left and abut against the push plate 16, and then start the second motor 15, the second motor 15 reverses to drive the second threaded rod 32 to rotate, the second threaded rod 32 drives the U-shaped frame 141 to move to the left through the second slider 33, the U-shaped frame 141 drives the aluminum plate and the first mounting plate 23 to move to the left, the first mounting plate 23 drives the second gear 25 to move to the left through the first rotating shaft 24, the second gear 25 drives the first rotating shaft 24 to rotate under the action of meshing with the second rack 26, the first rotating shaft 24 drives the first rack 21 to move to the left through the first gear 22, the first rack 21 drives the push plate 16 to move to the left through the moving rod 20, so that the push plate 16 will not hinder the subsequent movement of the aluminum plate to the left. When the push plate 16 abuts against the left side of the U-shaped frame 141, the second gear 25 just disengages from the second rack 26, and the third gear 30 just engages with the third rack 27, and then the U-shaped frame 141 continues to move to the left, the U-shaped frame 141 drives the second mounting plate 28 to move left, and the second mounting plate 28 drives the third gear 30 and the fourth gear 34 to move through the second rotating shaft 29. Under the action of the engagement of the third gear 30 and the third rack 27, the second rotating shaft 29 is driven to rotate, the second rotating shaft 29 drives the fourth gear 34 to rotate, the fourth gear 34 drives the fifth gear 35 to rotate, the fifth gear 35 drives the fourth rack 36 to move left, the fourth rack 36 drives the fourth slider 37 to move left, and the fourth slider 37 moves left. The fifth slider 39 is driven to move to the left through the hinge rod 40, and the fifth slider 39 drives the baffle 17 to move through the connecting rod 41. When the fifth slider 39 enters the fourth slide groove 38 from the fifth slide groove 42, the fifth slider 39 rotates and drives the connecting rod 41 to be horizontal at the same time. At this time, the connecting rod 41 drives the baffle 17 to contact the front side of the aluminum plate, and then continues to move the U-shaped frame 141 to the left, thereby continuing to drive the fifth slider 39 to slide along the fourth slide groove 38. The fifth slider 39 drives the baffle 17 to move to the left through the connecting rod 41. The baffle 17 pushes the front end of the aluminum plate to drive the aluminum plate to move to the left. When the rear side of the aluminum plate abuts against the push plate 16, the baffle 17 just abuts against the front end of the U-shaped frame 141, that is, the loading of the aluminum plate is completed. At the same time, the baffle 17 and the push plate 16 can position the aluminum plate to prevent the aluminum plate from moving during the cutting process.
