Description

Technical Field

[0001] This application relates to the field of cutting equipment, and more particularly to a laser cutting apparatus for preparing aluminum honeycomb panels. Background Technology

[0002] Laser cutting equipment is an industrial device that uses a high-power-density laser beam to cut and process materials. Its core principle is to melt / vaporize the material by focusing the laser, and then use auxiliary gas to blow away the slag to form a cut. It is a high-end processing equipment commonly used in modern manufacturing. Aluminum honeycomb panel laser cutting equipment is a special cutting equipment designed for the special structure of aluminum honeycomb panels. Compared with general cutting machines, it solves the problem of easy deformation when ordinary laser cutting aluminum honeycomb panels.

[0003] The main reason for deformation of aluminum honeycomb panels caused by conventional laser cutting is the large coefficient of thermal expansion of aluminum, which leads to local heat accumulation and deformation. To reduce deformation caused by laser cutting, existing aluminum honeycomb panel laser cutting equipment usually adopts a double-sided cooling method. By spraying coolant on both sides of the cutting position, the probability of deformation caused by excessive local temperature at the cutting position is reduced. However, the cooling pipes located under the aluminum honeycomb panel in existing laser cutting equipment are not easy to observe, so it is difficult to control their movement in conjunction with the laser cutting equipment. This can easily lead to the coolant not being able to effectively act on the cutting area, resulting in deformation of the aluminum honeycomb panel during the cutting process. Summary of the Invention

[0004] To improve the cooling effect during laser cutting, this application provides a laser cutting apparatus for preparing aluminum honeycomb panels.

[0005] The laser cutting device for manufacturing aluminum honeycomb panels provided in this application adopts the following technical solution: A laser cutting device for manufacturing aluminum honeycomb panels includes a base, a laser cutting head mounted on the base, a driving assembly between the base and the laser cutting head, the driving assembly driving the laser cutting head to slide along three axes in the length, width and height directions of the base, an upper cooling assembly mounted on the laser cutting head, a sliding block slidably mounted on the base, a sliding assembly between the sliding block and the base, the sliding assembly driving the sliding block to slide along three axes in the length, width and height directions of the base, a lower cooling assembly mounted on the sliding block, a signal transmitter mounted on the laser cutting head, and a signal receiver mounted on the sliding block corresponding to the signal transmitter, the sliding assembly causing the signal receiver to slide and align with the signal transmitter.

[0006] By adopting the above technical solution, after the signal transmitter emits a signal, the signal receiver receives the signal emitted by the signal transmitter. Then, the sliding component moves to align the signal transmitter and the signal receiver, thereby ensuring that the lower cooling component is aligned with the upper cooling component. This ensures that the lower cooling component is located in the laser cutting area when the laser cutting head performs laser cutting, thereby improving the cooling effect during laser cutting and reducing the probability of deformation of the aluminum honeycomb panel during laser cutting.

[0007] Preferably, the upper cooling assembly includes an upper cooling ring, an upper liquid inlet pipe, and an upper liquid outlet pipe. The upper cooling ring is mounted on the laser cutting head and is a hollow ring. The upper liquid inlet pipe is connected to and communicates with the upper cooling ring, and the upper liquid outlet pipe is connected to and communicates with the upper cooling ring. The lower cooling assembly includes a lower cooling ring, a lower liquid inlet pipe, and a lower liquid outlet pipe. The lower cooling ring is mounted on a sliding block and is a hollow ring. The lower liquid inlet pipe is connected to and communicates with the lower cooling ring, and the lower liquid outlet pipe is connected to and communicates with the lower cooling ring.

[0008] By adopting the above technical solution, the cooling component uses a hollow cooling ring. Coolant is introduced into the cooling ring through an inlet pipe, and then heat exchange occurs between the cooling ring and the aluminum honeycomb panel. This reduces the temperature of the aluminum honeycomb panel and decreases the probability of deformation caused by excessive local temperature during cutting. Compared with spray cooling, the cooling ring design reduces the probability of coolant turbulence in the base and also reduces coolant consumption. Furthermore, the cooling ring's contact with the laser cutting area reduces the probability of deviation in the cutting position caused by force shift during cutting.

[0009] Preferably, the sliding assembly includes a lateral sliding cylinder, a longitudinal sliding cylinder, a lifting cylinder, and a sliding control module. The lateral sliding cylinder is installed in the width direction of the base, and the longitudinal sliding cylinder is installed on the lateral sliding cylinder. The lateral sliding cylinder drives the longitudinal sliding cylinder to slide along the length direction of the base. The lifting cylinder is installed on the longitudinal sliding cylinder, and the longitudinal sliding cylinder drives the lifting cylinder to slide along the width direction of the base. The lower cooling assembly is installed on the lifting cylinder, and the lifting cylinder drives the lower cooling assembly to slide along the height direction of the base. The sliding control module is electrically connected to the lateral sliding cylinder, the longitudinal sliding cylinder, and the lifting cylinder, and controls the start and stop of the lateral sliding cylinder, the longitudinal sliding cylinder, and the lifting cylinder.

[0010] By adopting the above technical solution, the sliding component can be configured to align the lower cooling component with the upper cooling component by analyzing signal data through the control module.

[0011] Preferably, the base is provided with several support plates.

[0012] By adopting the above technical solution, the support plate can support the aluminum honeycomb panel, thereby facilitating the placement of the aluminum honeycomb panel and assisting in laser cutting.

[0013] Preferably, the support plate is hinged to the base, and a torsion spring is provided between the support plate and the base. The elastic force of the torsion spring drives the support plate to be vertically mounted on the base, and the longitudinal sliding electric cylinder is spaced apart from the bottom of the base.

[0014] By adopting the above technical solution, the hinged support plate can be driven by the longitudinal sliding electric cylinder to rotate when the longitudinal sliding electric cylinder is stationary, thereby reducing the influence of the support plate on the sliding of the longitudinal sliding electric cylinder. The torsion spring can drive the rotated support plate to reset after the longitudinal sliding electric cylinder moves away, thereby abutting against the aluminum honeycomb panel.

[0015] Preferably, the support plate array is distributed on the base, and the support plates in adjacent columns are staggered.

[0016] By adopting the above technical solution, the staggered support plate can be positioned between two adjacent support plates when the support plate rotates, thereby appropriately shortening the distance between the support plates of adjacent columns and making reasonable use of space.

[0017] Preferably, the support plate is triangular in shape, and the bottom edge of the triangular support plate is hinged to the base.

[0018] By adopting the above technical solution, the triangular support plate can fit smaller between two adjacent support plates after rotation, thus making better use of space when the support plates are distributed, so that the spacing between adjacent support plates in the same column can be smaller.

[0019] Preferably, a plurality of abutment blocks are evenly arranged on both sides of the longitudinal sliding electric cylinder along the width direction of the base.

[0020] By adopting the above technical solution, the abutting block on the longitudinal sliding electric cylinder can temporarily act as a support plate by abutting the aluminum honeycomb panel after the longitudinal sliding cylinder drives the corresponding position support plate to rotate.

[0021] Preferably, the signal transmitter transmits coordinate signals, and the signal receiver receives the coordinate signals.

[0022] By adopting the above technical solution, the coordinates of the upper cooling component are sent to the signal receiver after the upper cooling component moves by presetting the coordinate origin. After receiving the coordinate data, the signal receiver drives the lower cooling component to move to the same coordinates, so that both the upper and lower cooling components can act on the laser cutting area during laser cutting, thereby improving the cooling effect.

[0023] Preferably, the signal transmitter emits electromagnetic wave signals, and the signal receiver receives the electromagnetic wave signals.

[0024] By adopting the above technical solution, the signal transmitter emits a continuous electromagnetic signal, and the sliding component drives the lower cooling component to slide. When the signal receiver receives the electromagnetic signal from the signal transmitter, the lower cooling component and the upper cooling component are aligned, so that both the upper and lower cooling components can act on the laser cutting area during laser cutting, thereby improving the cooling effect.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. After the signal transmitter emits a signal, the signal receiver receives the signal emitted by the signal transmitter. Then, the sliding component moves the signal transmitter and the signal receiver to align, thereby ensuring that the lower cooling component is aligned with the upper cooling component. This ensures that the lower cooling component is located in the laser cutting area when the laser cutting head is performing laser cutting, thereby improving the cooling effect during laser cutting and reducing the probability of deformation of the aluminum honeycomb panel during laser cutting. 2. The cooling component adopts a hollow cooling ring. Coolant is introduced into the cooling ring through the inlet pipe. Then, the cooling ring is in contact with the aluminum honeycomb panel for heat exchange, thereby reducing the temperature of the aluminum honeycomb panel and reducing the probability of deformation caused by excessive local temperature during the cutting of the aluminum honeycomb panel. Compared with spray cooling, the setting of the cooling ring can reduce the probability of coolant turbulence in the base and also reduce coolant consumption. At the same time, the contact of the cooling ring can clamp the laser cutting area, reducing the probability of the aluminum honeycomb panel being shifted due to force during cutting, resulting in deviation of the cutting position. 3. The support plate can support the aluminum honeycomb panel, which facilitates the placement of the aluminum honeycomb panel and assists laser cutting. The hinged support plate can rotate at the corresponding position when the longitudinal sliding electric cylinder is stopped, thereby reducing the influence of the support plate on the sliding of the longitudinal sliding electric cylinder. The torsion spring can drive the rotated support plate to reset after the longitudinal sliding electric cylinder moves away, thereby abutting and supporting the aluminum honeycomb panel. 4. By using a preset coordinate origin, the coordinates of the upper cooling component are sent to the signal receiver after the upper cooling component moves. After receiving the coordinate data, the signal receiver drives the lower cooling component to move to the same coordinates, so that both the upper and lower cooling components can act on the laser cutting area during laser cutting, thereby improving the cooling effect. 5. The signal transmitter continuously emits electromagnetic signals, and the sliding component drives the lower cooling component to slide. When the signal receiver receives the electromagnetic signal from the signal transmitter, the lower cooling component and the upper cooling component align, so that both the upper and lower cooling components can act on the laser cutting area during laser cutting, thereby improving the cooling effect.

[0034] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail. Example 1

[0035] This application discloses a laser cutting apparatus for preparing aluminum honeycomb panels, referring to... Figure 1 , Figure 2 and Figure 6The system includes a rectangular base 1, a control panel 2 on the base 1, and a laser cutting head 3 mounted on the base 1. In this embodiment, the laser cutting head 3 is a conventional laser cutting head 3 found in existing laser cutting machines. A drive assembly 4 is positioned between the base 1 and the laser cutting head 3, driving the laser cutting head 3 to slide along three axes: length, width, and height of the base 1. An upper cooling assembly 5 is mounted on the laser cutting head 3. A sliding block 6 is slidably mounted on the base 1. A sliding assembly 7 is positioned between the sliding block 6 and the base 1, driving the sliding block 6 to slide along three axes: length, width, and height of the base 1. A lower cooling assembly 8 is mounted on the sliding block 6. A signal transmitter 9 is mounted on the laser cutting head 3, and a signal receiver 10 is mounted on the sliding block 6 corresponding to the signal transmitter 9. The sliding assembly 7 causes the signal receiver 10 to slide relative to the signal transmitter 9. Alignment: After the signal transmitter 9 emits a signal, the signal receiver 10 receives the signal emitted by the signal transmitter 9. Then, the sliding component 7 moves the signal transmitter 9 and the signal receiver 10 to align, thereby ensuring that the lower cooling component 8 and the upper cooling component 5 are aligned. This ensures that the lower cooling component 8 is located in the laser cutting area when the laser cutting head 3 performs laser cutting, thereby improving the cooling effect during laser cutting and reducing the probability of deformation of the aluminum honeycomb panel during laser cutting. The signal transmitter 9 emits coordinate signals, and the signal receiver 10 receives the coordinate signals. Through the preset coordinate origin, after the upper cooling component 5 moves, the coordinates of the upper cooling component 5 are sent to the signal receiver 10. After receiving the coordinate data, the signal receiver 10 drives the lower cooling component 8 to move to the same coordinates, so that both the upper cooling component 5 and the lower cooling component 8 can act on the laser cutting area during laser cutting, thereby improving the cooling effect.

[0036] Reference Figure 1 and Figure 2The upper cooling assembly 5 includes an upper cooling ring 51, an upper liquid inlet pipe 52, and an upper liquid outlet pipe 53. The upper cooling ring 51 is mounted on the laser cutting head 3 and is a hollow ring. The upper liquid inlet pipe 52 and the upper liquid outlet pipe 53 are connected to and communicate with the upper cooling ring 51. A condensation device for circulating and transporting coolant is connected through the upper liquid inlet pipe 52 and the upper liquid outlet pipe 53. The lower cooling assembly 8 includes a lower cooling ring 81, a lower liquid inlet pipe 82, and a lower liquid outlet pipe 83. The lower cooling ring 81 is mounted on the sliding block 6 and is a hollow ring. The lower liquid inlet pipe 82 and the lower liquid outlet pipe 83 are connected to and communicate with the lower cooling ring 6. On the lower cooling ring 81, a condensation device for circulating and transporting coolant is connected through the lower liquid inlet pipe 82 and the lower liquid outlet pipe 83. The cooling component adopts a hollow cooling ring. The coolant is introduced into the cooling ring through the liquid inlet pipe, and then heat exchange occurs through the cooling ring and the aluminum honeycomb panel, thereby reducing the temperature of the aluminum honeycomb panel and reducing the probability of deformation caused by excessive local temperature during the cutting of the aluminum honeycomb panel. Compared with spray cooling, the setting of the cooling ring can reduce the probability of turbulence of coolant in the base 1, and also reduce the consumption of coolant. At the same time, the contact of the cooling ring can clamp the laser cutting area, reducing the probability of deviation of the cutting position caused by force displacement of the aluminum honeycomb panel during cutting.

[0037] Reference Figure 1 and Figure 2 The sliding assembly 7 includes a lateral sliding cylinder 71, a longitudinal sliding cylinder 72, a lifting cylinder 73, and a sliding control module 74. The lateral sliding cylinder 71 is mounted on the width direction of the base 1, and the longitudinal sliding cylinder 72 is mounted on the lateral sliding cylinder 71. The lateral sliding cylinder 71 drives the longitudinal sliding cylinder 72 to slide along the length direction of the base 1. The lifting cylinder 73 is mounted on the longitudinal sliding cylinder 72, and the longitudinal sliding cylinder 72 drives the lifting cylinder 73 to slide along the width direction of the base 1. The lower cooling assembly 8 is mounted on the lifting cylinder 73, and the lifting cylinder 73 drives the lower cooling assembly 8 to slide along the height direction of the base 1. The sliding control module 74 is electrically connected to the lateral sliding cylinder 71, the longitudinal sliding cylinder 72, and the lifting cylinder 73. The sliding control module 74 controls the start and stop of the lateral sliding cylinder 71, the longitudinal sliding cylinder 72, and the lifting cylinder 73. In this embodiment, the sliding control module 74 is connected to the signal receiver 10. After receiving the coordinate signal from the signal transmitter 9, the signal receiver 10 feeds it back to the sliding control module 74. After reading the coordinate information, the sliding control module 74 drives the lateral sliding cylinder 71, the longitudinal sliding cylinder 72, and the lifting cylinder 73 to move the lower cooling component 8 to the corresponding coordinate position.

[0038] Reference Figure 3 and Figure 4The drive assembly 4 includes a transverse drive cylinder 41, a drive frame 42, a longitudinal drive cylinder 43, and a lifting cylinder 44. The transverse drive cylinder 41 is installed on both sides of the base 1 in the width direction. The drive frame 42 is mounted on the two transverse drive cylinders 41. The transverse drive cylinders 41 drive the drive frame 42 to slide along the length direction of the base 1. The longitudinal drive cylinder 43 is installed on the drive frame 42. The lifting cylinder 44 is installed on the longitudinal cylinder. The longitudinal drive cylinder 43 drives the lifting cylinder 44 to slide along the width direction of the base 1. The laser cutting head 3 is installed on the lifting cylinder 44. The lifting cylinder 44 drives the laser cutting head 3 to slide along the height direction of the base 1.

[0039] Reference Figure 1 , Figure 2 and Figure 5 The base 1 is provided with several support plates 11, which support the aluminum honeycomb panel, facilitating its placement and assisting in laser cutting. The support plates 11 are arranged in an array on the base 1, with adjacent columns staggered. Each support plate 11 is triangular in shape, with its base hinged to the base 1. A torsion spring 12 is installed between the support plate 11 and the base 1, and the spring force of the torsion spring 12 drives the support plate 11 vertically onto the base 1. A longitudinal sliding electric cylinder 72 is spaced apart from the bottom of the base 1. The hinged support plates 11 can... When the longitudinal sliding cylinder 72 is stationary, the support plate 11 at the corresponding position is rotated by the longitudinal sliding cylinder 72, thereby reducing the influence of the support plate 11 on the sliding of the longitudinal sliding cylinder 72. The torsion spring 12 is set so that the support plate 11 driven to rotate can be reset after the longitudinal sliding cylinder 72 moves away, thereby abutting against the aluminum honeycomb panel. Several abutting blocks 13 are evenly arranged on both sides of the longitudinal sliding cylinder 72 along the width direction of the base 1. The abutting blocks 13 on the longitudinal sliding cylinder 72 can abut against the aluminum honeycomb panel and temporarily act as the support plate 11 after the longitudinal sliding cylinder drives the support plate 11 at the corresponding position to rotate.

[0040] The implementation principle of this application embodiment is as follows: The aluminum honeycomb panel to be laser-cut is placed on the base 1 and supported by the support plate 11. Then, according to the cutting requirements, the operation is performed on the control panel 2. The laser cutting head 3 is driven to move and perform laser cutting by the drive component 4. At the same time, the upper cooling component 5 is driven to cool down the laser cutting area. While the drive component 4 drives the laser cutting head 3 to slide, the signal transmitter 9 sends the coordinates of the laser cutting head 3 to the signal receiver 10. After receiving the coordinate data, the signal receiver 10 analyzes the data and feeds back the data. Then, the lower cooling component 8 is controlled to move to the same coordinates by the sliding component 7. Thus, both the upper cooling component 5 and the lower cooling component 8 can act on the laser cutting area during laser cutting, thereby improving the cooling effect during laser cutting. Example 2

[0041] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the signal transmitter 9 and the signal receiver 10 in this embodiment are different from those in embodiment 1.

[0042] Reference Figure 1 and Figure 7 The signal transmitter 9 emits electromagnetic wave signals, and the signal receiver 10 receives the electromagnetic wave signals. The signal transmitter 9 continuously emits electromagnetic signals, and the sliding component 7 drives the lower cooling component 8 to slide. When the signal receiver 10 receives the electromagnetic signal from the signal transmitter 9, the lower cooling component 8 and the upper cooling component 5 are aligned, so that both the upper cooling component 5 and the lower cooling component 8 can act on the laser cutting area during laser cutting, thereby improving the cooling effect. In this embodiment, the sliding control module 74 receives the sliding drive parameters of the drive component 4 and controls the horizontal sliding cylinder 71, the vertical sliding cylinder 72, and the lifting cylinder 73 to slide according to the sliding drive parameters of the drive component 4. When the signal receiver 10 is not aligned with the signal transmitter 9 after adjustment according to the sliding drive parameters of the drive component 4, the sliding control module 74 drives the horizontal sliding cylinder 71, the vertical sliding cylinder 72, and the lifting cylinder 73 to make fine adjustments until the signal receiver 10 is aligned with the signal transmitter 9.

[0043] The implementation principle of this embodiment is as follows: The aluminum honeycomb panel to be laser-cut is placed on the base 1 and supported by the support plate 11. Then, according to the cutting requirements, the operation is performed on the control panel 2. The laser cutting head 3 is driven to move and perform laser cutting by the drive component 4. At the same time, the upper cooling component 5 is driven to cool the laser cutting area. While the drive component 4 drives the laser cutting head 3 to slide, the sliding component 7 drives the lower cooling component 8 to slide. The signal transmitter 9 sends an electromagnetic wave signal. When the signal receiver 10 receives the electromagnetic signal from the signal transmitter 9, the lower cooling component 8 and the upper cooling component 5 are aligned, so that both the upper cooling component 5 and the lower cooling component 8 can act on the laser cutting area during laser cutting. When the signal receiver 10 does not receive the electromagnetic wave signal from the signal transmitter 9, the drive component 4 drives the lower cooling component 8 to adjust its position until it is aligned with the upper cooling component 5. The advantage of this embodiment is that it can align the lower cooling component 8 and the upper cooling component 5. At the same time, if misalignment occurs, the alignment of the lower cooling component 8 and the upper cooling component 5 can be maintained by adjustment. This embodiment can also be used simultaneously with embodiment 1 to achieve positioning and adjustment alignment at the same time.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
