Description

Technical Field

[0001] The invention relates to the technical field of flame cutting processing, in particular to a double-sided numerical control cutting machine. Background Art

[0002] Flame cutting uses a gas flame (a flame formed by oxygen and fuel gas) to heat the surface of the steel plate to a local combustion temperature, and then introduces a high-purity, high-speed cutting oxygen flow to cause the metal to undergo a violent combustion reaction and release heat. At the same time, the huge kinetic energy of the high-speed cutting oxygen flow is used to blow away the combustion products and form a cutting seam. In industrial production, flame double-sided CNC cutting machines are usually used to cut and process metal plates.

The device can self-lock in time to make the equipment quickly and stably fixed, and the equipment is retractable, and the distance of the flame during cutting can be adjusted to achieve more reasonable cutting. However, in actual use, when the device and the existing equipment perform flame cutting on metal plates, since the metal plates usually contain impurities with a higher melting point, these impurities are still adhered to the cut-off points of the two cut metal plates after the metal plates are flame cut. The existing technology usually uses the method of increasing the temperature of the flame for cutting. However, excessively increasing the flame temperature can easily cause the metal plates to be overburned, resulting in inconsistent cutting marks, thereby reducing the flame cutting quality of the device. The existing equipment has further room for improvement in the flame cutting quality of metal plates. Summary of the invention

[0032] Working principle: Place the metal sheet on the processing platform 10, use the clamping assembly 11 to fix and clamp the metal sheet, then open the moving assembly 12 to move the flame cutting assembly 3 to the metal sheet for cutting. As the moving assembly 12 drives one end of the flame cutting assembly 3 to move, the flame sprayed from the nozzle 31 cuts the metal sheet. At the same time, the nozzle inside the gas supply chamber 30 sprays oxygen to blow away the impurities generated by cutting, so that the metal sheet can get a complete cutting gap. Then separate the first clamping rod 32 from the first clamping member 40. At this time, the auxiliary After the device 4 loses its restriction, the auxiliary device 4 can be rotated 90 degrees counterclockwise through the first connecting member 33, the first rotating rod 330, the first telescopic rod 331, and the second connecting member 41 by loosening the tension bolt.

During the downward pressing process, the pressure knife 487 contacts the impurities with a high melting point that are still adhered to the cutting gap of the cut metal plate after flame cutting, and presses and cuts them together. The first rotary drive component 42 drives the rotating shaft 420 to intermittently rotate forward and reverse, so that the pressure knife 487 can move up and down normally, thereby improving the flame cutting processing quality of the device and facilitating user use. In the above steps, the first movable wheel 421 rotates to drive the fixed rod 422 to rotate, the fixed rod 422 rotates to drive the adjusting arm 423 to rotate, the adjusting arm 423 rotates to drive the movable shaft 424 to rotate, the movable shaft 424 rotates to drive the return groove plate 43 to make a linear reciprocating motion, the return groove plate 43 moves through the fixed block 430 to drive the top side tooth plate 44 to make a linear reciprocating motion, the top side tooth plate 44 moves to drive the tooth plate 450 to rotate, and then the rotation of the tooth plate 450 can drive the bottom side tooth plate 44 to make a linear reciprocating motion in the opposite direction of the top side tooth plate 44, and the two tooth plates The linear reciprocating motion of 44 drives the connecting plate 441 to move, and the movement of the connecting plate 441 drives the grinding plate 442 to make a linear reciprocating motion at the cut end face of the metal plate. The grinding plate 442 moves to scrape off the impurities cut off by the pressure plate. At the same time, the L-shaped structure of the grinding plate 442 enables it to grind the cut end face of the metal plate during the linear reciprocating motion, thereby avoiding the fracture marks at the cut end face of the metal plate after flame cutting, making the cut end face of the metal plate uneven, thereby reducing the flame cutting effect of the device, improving the flame cutting processing quality of the device, and facilitating the use of users; In the above steps, due to the splashing of impurities in some metal plates during flame cutting and the flying of impurity dust during the grinding process of the grinding plate 442, the nozzle 31 of the flame cutting component 3 is easily blocked by impurities. At this time, the user can remove the second clamping rod 50 from the flame cutting component 3 and loosen the tensioning bolt here so that the clearing device 5 can be rotated 180 degrees through the fourth connecting piece 51 and the third rotating rod 510, and then fasten the tensioning bolt to fix the current position of the clearing device 5, and use the control center 13 to start the second rotation drive component 52. The second rotation drive component 52 is turned on to drive the screw rod 520 to rotate. The rotation of the screw rod 520 drives the movable block 53 to move upward, and the slide rod 530 is used to The movement of the movable block 53 is limited, and the movement of the movable block 53 drives the top plate 54 to move. The movement of the top plate 54 drives the driving platform 540 and the clearing rod 541 to move upward. The control center 13 is used to turn on the driving platform 540, and the driving platform 540 drives the clearing rod 541 to rotate. At this time, as the top plate 54 continues to move upward, the clearing rod 541 moves to the inside of the nozzle 31 and rotates to clean the inner wall of the nozzle 31 to avoid the flame cutting component 3 being blocked due to slag splashing during the flame cutting process, resulting in insufficient preheating flame power and cutting oxygen flow momentum, resulting in the flame cutting failing to reach the melting point and unable to cut the metal sheet normally, thereby improving the flame cutting processing quality of the device and facilitating user use.
