Description

Technical Field

[0001] The invention relates to the technical field of aluminum veneer processing, and in particular to an aluminum veneer laser cutting machine for precision numerical control processing. Background Art

[0002] In the field of aluminum veneer processing technology, laser cutting machine is the key equipment for realizing precision CNC processing. Aluminum veneer is widely used in many fields such as architectural decoration due to its excellent performance. Laser cutting, as a high-precision processing method, plays a vital role in the fine processing of aluminum veneer.

[0003] In the process of laser cutting aluminum veneer, effective removal of slag is one of the key factors to ensure cutting quality. For thin aluminum veneer with a thickness of less than 6mm, a certain amount of slag will be generated during laser cutting. At present, auxiliary blowing is usually used to blow away the slag. This method can meet the cutting requirements of thin aluminum veneer to a certain extent, so that the slag can be separated from the cutting area more smoothly, thereby ensuring the flatness and smoothness of the cut surface. However, when it comes to cutting thick aluminum veneer with a thickness greater than 6mm, the situation becomes more complicated. Thick aluminum veneer will produce a large amount of more stubborn slag during the laser cutting process. The traditional auxiliary and continuous blowing method is difficult to completely blow away the slag. Since the slag generated by thick aluminum veneer is large in amount and has high viscosity, the continuous airflow cannot form a strong enough impact force to blow the slag out from the bottom of the deeper incision, causing the slag to easily accumulate at the incision, thereby affecting the cutting quality, resulting in uneven incisions, severe slag, etc., reducing the accuracy and pass rate of the product, and increasing the subsequent processing cost and time. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when cutting thick aluminum veneer with a thickness greater than 6mm, the traditional auxiliary and continuous blowing method is difficult to completely blow away the slag.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When cutting thin aluminum veneer with a thickness of less than 6mm, the auxiliary blowing component adopts continuous blowing to blow away the slag generated during cutting to prevent the slag from adhering to the incision and affecting the production quality. When cutting thick aluminum veneer with a thickness greater than 6mm, the setting of the component can be adjusted to automatically change the continuous blowing mode to pulse blowing. The auxiliary gas blown out by pulse will form an instantaneous high-pressure airflow in each pulse cycle. Compared with continuous blowing, this instantaneous high pressure can produce greater impact force and more effectively blow the slag generated during the cutting process of thick aluminum veneer from the incision. Especially for the slag attached to the deep incision or with high viscosity, the pulse airflow can more effectively remove it, and the periodic change of the pulse airflow will produce a certain vibration effect in the cutting area. This vibration can loosen the adhesion interface between the slag and the aluminum veneer, making it easier for the slag to detach from the surface of the plate and then be blown away by the airflow, which is conducive to improving the slag removal efficiency.

[0016] 2. Through the setting of the rotating component, while adjusting the component for pulse blowing, the outlet pipe and nozzle can also be rotated intermittently. When cutting thick aluminum veneer, the slag can be impacted from different directions, expanding the scope of blowing, avoiding the inability to blow off in time due to excessive solution, and further improving the blowing effect of the slag.

[0017] 3. Through the setting of the compression part, the adjustment component can maintain pulsed blowing while also cooperating with the rectangular groove, ball, air cushion, air bag 1 and hose 3 to enable the sealing disk to maintain good movement under the action of pressure. At the same time, through the setting of hose 4 and air bag 2, when the thickness of the aluminum veneer gradually increases, the blowing port of the nozzle can be synchronously reduced, so that the gas is compressed in the local area, thereby causing the ejected gas pressure to increase, further improving the blowing effect on the slag.

[0027] In summary, during the specific cutting, the aluminum veneer is transported to the processing area 28 by the movement of the loading roller 26, and is used to clamp the aluminum veneer by installing a fixing mechanism. The fixing mechanism can be composed of an electric push rod and a clamping block. This is the existing technology, so I will not go into details here. The mounting frame 22 and the lifting frame 24 are driven downward by the cylinder 1 21 to change the longitudinal position of the laser cutting head 25, so that the laser cutting head 25 is moved to the top of the aluminum veneer, and the laser cutting head 25 is connected to the external equipment for cutting. The laser cutting head 25 can be driven to move horizontally by the cylinder 2 23 to complete the cutting operation.

[0028] Considering that slag will be generated during cutting, which will easily accumulate at the incision and affect the cutting quality, the following improvements are made: When cutting thin aluminum veneer with a thickness of less than 6 mm, by opening the valve on the hose 33, the gas in the gas tank 32 enters the installation box 31 through the hose 33 and the air outlet shell 34, and is blown out from the air outlet pipe 35 and the nozzle 36. Since the air outlet pipe 35 is arranged on both sides of the laser cutting head 25, a relative air flow is formed. In this way, continuous blowing is used to blow away the slag generated during cutting to prevent the slag from adhering to the incision and affecting the production quality. At this time, the air outlet shell 34, which is not under pressure, is located above the rectangular shell 411.

[0029] When cutting a thick aluminum veneer with a thickness greater than 6 mm, the aluminum veneer will conflict with the resistance block 45 when the aluminum veneer is placed in the processing area 28. The aluminum veneer is tilted on one side of the resistance block 45, so that the aluminum veneer can pass through the resistance block 45 more easily. Since the thickness of the aluminum veneer is greater than 6 mm, it will generate upward pressure on the resistance block 45, thereby driving the slide rod 44 and the piston plate 1 43 to slide upward in the piston cylinder 1 42, squeezing the spring 2 46. The liquid in the piston cylinder 1 42 is squeezed by the piston plate 1 43 and enters the piston cylinder 2 48 through the hose 2 47. After the piston plate 2 49 is squeezed by the liquid, it will drive the lifting rod 4 10 and the air outlet shell 34 move downward, squeezing the spring 1 40, so that the air outlet shell 34 moves to the rectangular shell 411, corresponding to the position of the air inlet 412, until the air flow can enter the installation cavity 1 414, and the rectangular shell 411 slides in the limit bar 425 through the lifting block 426, and the spring 427 is set to support the lifting block 426 and the rectangular shell 411. The purpose of this design is that when the thickness of the aluminum single plate continues to increase, the air outlet shell 34 can drive the rectangular shell 411 to move downward together through the interference with the limit block 413, so as to ensure that the air inlet 412 will not be affected by the continuous increase in the thickness of the aluminum single plate. The air inlet 412 is separated from the air outlet shell 34, so that the gas blown out from the air outlet shell 34 can be continuously blown into the installation cavity 1 414, and the blown air flow can drive the impeller 417 in the installation cavity 1 414 to rotate. At the same time, the air flow is blown out from the air outlet 416. When the impeller 417 rotates, it drives the rotating shaft and the turntable 418 to rotate. The turntable 418 drives the push pin 419 to make a circular motion. The push pin 419 pushes the movable shell 420 and the L-shaped rod 421 to move back and forth. Through the connection of the compression piece, the L-shaped rod 421 can drive the blocking disk 4224 to move back and forth in the direction of the air outlet pipe 35, so that the blocking disk 4224 can intermittently block the opening of the air outlet pipe 35, which will be sustained. The continuous blowing mode is changed to pulse blowing. The auxiliary gas blown out by pulse blowing will form an instantaneous high-pressure airflow in each pulse cycle. Compared with continuous blowing, this instantaneous high pressure can produce greater impact force, and more effectively blow the slag generated during the cutting process of thick aluminum veneer from the incision. Especially for the slag attached to the deep part of the incision or with high viscosity, the pulse airflow can more effectively remove it, and the periodic change of the pulse airflow will produce a certain vibration effect in the cutting area. This vibration can loosen the adhesion interface between the slag and the aluminum veneer, making it easier for the slag to detach from the surface of the plate and then be blown away by the airflow, which is beneficial to improve the slag removal efficiency.

[0030] It should be noted that in order to ensure that the gas can drive the impeller 417 and other components to rotate, the impeller 417, the turntable 418, the push pin 419, the moving shell 420, the L-shaped rod 421 and the sealing disk 4224 and other components can be made of plastic materials.

[0031] Example 2, refer to Figures 1-11 , an aluminum single plate laser cutting machine for precision CNC processing, comprising a frame 1, and also comprising: Laser cutting components, used for laser cutting of aluminum veneers; Auxiliary air blowing component, used to blow off the slag generated during cutting when cutting thin aluminum veneer with a thickness of less than 6mm; Adjust the component to change the blowing mode of the auxiliary blowing component when cutting thick aluminum veneer with a thickness greater than 6mm; The laser cutting assembly, the auxiliary blowing assembly and the adjustment assembly are all installed on the frame 1.

[0032] Furthermore, the compression part includes a connecting block 4220 fixed to one end of the L-shaped rod 421 away from the movable shell 420, and the bottom of the connecting block 4220 is fixed with a movable block 4222 through a telescopic rod 4221. The outer surface of the telescopic rod 4221 is sleeved with a spring three 4223, and the two ends of the spring three 4223 are respectively connected to the connecting block 4220 and the movable block 4222, and the sealing disk 4224 is fixed on the movable block 4222.

[0033] Furthermore, a rectangular groove 61 is provided on the bottom wall of the mounting box 31, a ball 62 is rollingly connected in the rectangular groove 61, the bottom of the movable block 4222 is in contact with the ball 62, an air cushion 63 is fixed in the rectangular groove 61, an air bag 1 64 is fixed between the connecting block 4220 and the movable block 4222, and a hose 3 65 is connected between the air bag 1 64 and the air cushion 63.

[0034] Furthermore, the outer surface of the airbag 1 64 is also connected to a hose 4 71 , an airbag 2 72 is fixed in the air outlet pipe 35 , and the end of the hose 4 71 away from the airbag 1 64 is connected to the airbag 2 72 .

[0035] The compression part is composed of a connecting block 4220, a telescopic rod 4221, a moving block 4222 and a spring three 4223. The reason for this design is that, when the thickness of the aluminum veneer continues to increase, it is necessary to ensure that the height of the sealing disk 4224 is consistent with the air outlet pipe 35. This can ensure that when the thickness of the aluminum veneer exceeds 6 mm, the airflow can always be blown out in a pulsed manner, thereby improving the slag blowing effect. Therefore, through the connection between the connecting block 4220 and the moving block 4222 and the buffering of the telescopic rod 4221 and the spring three 4223, when the thickness of the aluminum veneer continues to increase, it will drive the connecting block 4220 to continue to approach the moving block 4222, so that the sealing disk 4224 will not be affected by the increase in the thickness of the aluminum veneer.

[0036] At the same time, considering that the bottom of the movable block 4222 needs to always be in contact with the bottom wall of the installation box 31, when the connecting block 4220 is affected by the continuous increase in the thickness of the aluminum single plate and approaches the movable block 4222, a large clamping force will be generated on the movable block 4222, thereby causing the movable block 4222 to be unable to move toward the direction of the air outlet pipe 35 under the drive of the L-shaped rod 421. Therefore, by arranging a rolling ball 62 in the rectangular groove 61, the movable block 4222 contacts the ball 62, which can effectively reduce the influence of friction. Even if the pressure increases, the movable block 4222 can slide relatively smoothly, thereby reducing the influence of pressure on the movable block 4222.

[0037] By arranging an airbag 64 between the connecting block 4220 and the moving block 4222, when the thickness of the aluminum veneer continues to increase and drives the connecting block 4220 to move toward the moving block 4222, the airbag 64 can be squeezed, so that the gas in the airbag 64 enters the air cushion 63 through the hose 3 65, causing the air cushion 63 to expand. The expanded air cushion 63 contacts the ball 62, so that the ball 62 will be wiped by the air cushion 63 when rolling, removing dust and oxides on the surface of the ball 62, making the surface of the ball 62 smoother, thereby reducing the friction coefficient between the ball 62 and the moving block 4222, making the sliding smoother, and improving the efficiency of the entire sliding system.

[0038] Moreover, through the compression of airbag 1 64, the gas can also enter airbag 2 72 through hose 3 65, causing airbag 2 72 to expand. Since airbag 2 72 is arranged in the air outlet pipe 35, when the thickness of the aluminum veneer increases, the expanded airbag 2 72 can synchronously shrink the blowing port of the nozzle 36, so that the gas is compressed in the local area, thereby causing the pressure of the ejected gas to increase, further improving the blowing effect on the slag.

[0039] Therefore, through the setting of the compression part, the adjustment component can not only maintain pulsed blowing, but also cooperate with the rectangular groove 61, the ball 62, the air cushion 63, the airbag 1 64 and the hose 3 65 to enable the sealing disk 4224 to maintain good movement under the action of pressure. At the same time, through the cooperation of the hose 4 71 and the airbag 2 72, the blowing effect of the slag is improved when the thickness of the aluminum single plate gradually increases.

[0040] Example 3, refer to Figures 1-11 , an aluminum single plate laser cutting machine for precision CNC processing, comprising a frame 1, and also comprising: Laser cutting components, used for laser cutting of aluminum veneers; Auxiliary air blowing component, used to blow off the slag generated during cutting when cutting thin aluminum veneer with a thickness of less than 6mm; Adjust the component to change the blowing mode of the auxiliary blowing component when cutting thick aluminum veneer with a thickness greater than 6mm; The laser cutting assembly, the auxiliary blowing assembly and the adjustment assembly are all installed on the frame 1.

[0041] Furthermore, a rotating assembly is provided on the air outlet pipe 35 , and the rotating assembly includes a rack 51 . The rack 51 is fixed on the moving block 4222 . A gear 52 is fixed on the outer surface of the air outlet pipe 35 , and the gear 52 is meshed and connected with the rack 51 .

[0042] It is connected to the moving block 4222 through the rack 51. When the moving block 4222 reciprocates toward the direction of the air outlet pipe 35, it will also drive the rack 51 to move together. The rack 51 drives the gear 52, the air outlet pipe 35 and the nozzle 36 to rotate reciprocatingly. When cutting thick aluminum veneer, the slag can be impacted from different directions, expanding the scope of blowing, avoiding the inability to blow off in time due to too much solution, and further improving the blowing effect of the slag.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
