Description

Technical Field

[0001] The present invention relates to the technical field of sheet cutting, and particularly to a cutting device for composite board production. Background Art

[0002] A composite board is a new type of board composed of two or more different materials combined in a certain proportion and structure, mainly including metal-plastic composite boards, metal-ceramic composite boards, fiber-reinforced composite boards, and honeycomb composite boards. The composite board can be changed in corresponding strength, structure, etc. according to the requirements of the usage scenario, so it is widely used in fields such as aerospace, architectural decoration, transportation, and sports and leisure. After the composite board is produced, it needs to be cut according to the designed size. The existing cutting methods include laser cutting and mechanical cutting, etc. Since laser cutting has advantages such as high precision and high automation, it is widely used. However, when the existing laser cutting equipment cuts a composite board with protrusions (folded protrusions), the laser line is always in the vertical direction. As a result, the "thickness" of the laser cutting of the composite board increases, there is a situation where the laser cutting is not in place, the cutting quality is reduced, and the laser scattering and reflection are increased, which affects the health of workers. Summary of the Invention

[0013] As a further preferred solution, a solenoid valve is installed at the connection between the shell and the intermediate pipe to control the connection state between the two.

Detailed implementation manner

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.

[0026] As Figures 1 - 3 and Figure 6 shown, an embodiment of the present invention provides a cutting device for producing composite boards, which is used for adaptively cutting a board to solve the problem that in the existing cutting process, the laser cutting line is not perpendicular to the plane of the board, resulting in an uneven cut and burrs, and at the same time reducing the distance that the laser penetrates the board, thereby reducing the loss of ineffective energy. The cutting device includes: a frame body 1; a moving module 2 installed on the frame body 1; a lifting module 3 installed on the moving module 2 through a mounting plate; a mounting frame 4 fixedly connected to the lifting module 3; a mounting part 5 rotatably connected to the mounting frame 4; a cutting module 6 installed on the mounting part 5; the moving module 2 and the lifting module 3 are respectively used to horizontally and vertically move the cutting module 6, facilitating the cutting module 6 to cut the material; a deflection mechanism arranged on the mounting frame 4 for detecting the inclination state of the cutting area of the material; a limiting mechanism arranged on the mounting frame 4 for enabling relative rotation between the mounting part 5 and the mounting frame 4.

[0027] In the above solution, the moving module 2, the lifting module 3, and the cutting module 6 are all prior arts. The moving module 2 and the lifting module 3 are used to adjust the spatial position of the cutting module 6, so that the cutting module 6 can move along the surface shape of the composite board 101, thereby ensuring the distance between the cutting module 6 and the surface of the composite board 101, ensuring that the laser focus point accurately falls on the surface of the composite board 101, realizing precise cutting, and further improving the cutting quality of the composite board 101. During the cutting process, the moving module 2 and the lifting module 3 move, thereby driving the cutting module 6 to move together, so as to cut the composite board 101. During the process, the relative rotation between the mounting bracket 4 and the mounting member 5 occurs through the deflection mechanism and the limiting mechanism, changing the deflection angle of the cutting module 6, so that the laser line emitted from the cutting module 6 is always perpendicular to the surface of the composite board 101 during the cutting process, maximizing the use of laser energy for cutting, reducing ineffective energy loss, while reducing the total path of the laser passing through the composite board 101, preventing the vertical "thickness" of the shape change area of the composite board 101 from increasing, resulting in incomplete laser cutting and reduced cutting quality, and reducing the situation of laser scattering and reflection, improving the protection of workers.

[0028] As Figures 2 - 5 shown, the deflection mechanism includes: a first deflection member 701, rotatably connected to the mounting bracket 4, and a spring is fixedly connected between the first deflection member 701 and the mounting bracket 4 for resetting the first deflection member 701; a support member 702, fixedly connected to the mounting bracket 4; a sliding shell 703, slidably connected to the support member 702, and a transmission medium is filled in the sliding shell 703; a deflection rod 704, fixedly connected to the first deflection member 701, the deflection rod 704 is slidably connected to the sliding shell 703, and an arc region is provided on the deflection rod 704. The sliding shell 703 is a part of a ring, and the center of the arc on the deflection rod 704, the center of the sliding shell 703, the cutting position of the cutting module 6, and the rotation center between the mounting member 5 and the mounting bracket 4 are on the same horizontal line. A through hole is provided on the deflection rod 704 for providing damping for the relative sliding between the sliding shell 703 and the deflection rod 704. A first elastic element 705 is fixedly connected between the sliding shell 703 and the deflection rod 704; a connecting rod 706, fixedly connected between the mounting member 5 and the sliding shell 703.

[0029] In the above solution, the first deflection member 701 is inclined, used to compress the first elastic element 705 during its contact with the composite board 101. The transmission medium in the sliding shell 703 is hydraulic oil, and the first elastic element 705 is a spring, used to apply pressure to the sliding shell 703, so that the sliding shell 703 and the support member 702 have relative sliding. When it is necessary to cut the composite board 101, the lifting module 3 drives the mounting bracket 4 and its parts to move downward together. After the first deflection member 701 moves downward to contact the composite board 101, the first deflection member 701 starts to deflect clockwise (asFigure 5 Taking the direction shown as an example, the first deflector 701 compresses the spring. The first deflector 701 drives the deflector rod 704 to deflect clockwise together. The deflector rod 704 drives the sliding housing 703 to deflect clockwise together through the compression of the first elastic element 705. The sliding housing 703 drives the mounting member 5 to deflect clockwise through the connecting rod 706. The mounting member 5 drives the cutting module 6 to deflect clockwise until the cutting module 6 moves downward to the height of the to-be-cut position and then stops moving (and stops deflecting clockwise at the same time). At this time, the cutting module 6 is perpendicular to the composite board 101, and the limiting mechanism limits (fixes) the sliding housing 703, and then starts to cut the composite board 101.

[0030] During the cutting process (taking the example of cutting the composite board 101 from left to right), when the first deflector 701 moves to the right and contacts the protrusion on the composite board 101, the first deflector 701 further deflects clockwise. Since the sliding housing 703 is limited by the limiting mechanism at this time, relative sliding occurs between the deflector rod 704 and the sliding housing 703, and the first elastic element 705 is compressed. During the process, the hydraulic oil at the lower part inside the sliding housing 703 moves to the upper part through the through hole on the deflector rod 704.

[0031] As Figures 3 - 7 As shown, the limiting mechanism includes: a moving frame 801, slidably connected to the mounting frame 4, and a second elastic element 802 is fixedly connected between the moving frame 801 and the mounting frame 4; a second deflector 803, rotatably connected to the mounting frame 4. The length of the first deflector 701 is less than the length of the second deflector 803, so that the second deflector 803 contacts the material first and makes the cutting module 6 deflect at the bending position of the composite board 101. A third elastic element 804 is fixedly connected between the second deflector 803 and the mounting frame 4; a limiting rod 805, fixedly connected to the second deflector 803, and the limiting rod 805 is in limiting cooperation with the moving frame 801; a limiting column 806, fixedly connected to the moving frame 801, and the sliding housing 703 is provided with limiting grooves 807 distributed at intervals, and the limiting grooves 807 are in limiting cooperation with the limiting column 806.

[0032] In the above solution, the second elastic element 802 is a tension spring, and the second elastic element 802 is initially in a stretched state, which is used to reset the moving frame 801. The third elastic element 804 is a spring, which is used to reset the second deflecting member 803 to limit and squeeze the moving frame 801. There are two limiting rods 805 distributed vertically, which are used to limit and squeeze the moving frame 801 during the different rotations of the second deflecting member 803. The lower limiting rod 805 is initially in a state of limiting and squeezing cooperation with the moving frame 801. The area where the moving frame 801 is in limiting cooperation with the limiting rod 805 is vertical. During the downward movement of the mounting frame 4, the mounting frame 4 drives the second deflecting member 803 to move downward together. After the second deflecting member 803 contacts the composite plate 101 during the downward movement, the second deflecting member 803 starts to deflect counterclockwise (taking the direction shown in Figure 3 as an example), the third elastic element 804 is compressed, the second deflecting member 803 drives the two limiting rods 805 to deflect counterclockwise together, and the lower limiting rod 805 gradually loses the limiting squeeze on the moving frame 801. The moving frame 801 moves to the right under the action of the pulling force of the second elastic element 802. The moving frame 801 drives the limiting post 806 to move to the right together. The limiting post 806 gradually enters the adjacent limiting groove 807, thereby limiting the sliding shell 703 and ensuring a relatively stable relationship between the sliding shell 703 and the deflecting rod 704 until the second deflecting member 803 deflects counterclockwise to the horizontal state (at this time, the cutting module 6 is perpendicular to the composite plate 101 and is in a state to be cut). At this time, both limiting rods 805 are in contact with the moving frame 801 and do not squeeze and limit the moving frame 801.

[0033] During the cutting process of the composite plate 101 from left to right, when the second deflecting member 803 contacts the protrusion on the composite plate 101, the second deflecting member 803 further deflects counterclockwise. The second deflecting member 803 drives the two limiting rods 805 to deflect counterclockwise together. The upper limiting rod 805 starts to squeeze the moving frame 801 to the left. The moving frame 801 moves to the left and stretches the second elastic element 802. The moving frame 801 drives the limiting post 806 to move to the left together. The limiting post 806 gradually disengages from the limiting groove 807 and gradually loses the limitation on the sliding shell 703. Subsequently, the sliding shell 703 slides relative to the support member 702 under the action of the elastic force of the first elastic element 705 (the sliding shell 703 deflects clockwise, taking the direction shown in Figure 5 as an example). The sliding shell 703 drives the mounting member 5 to deflect clockwise through the connecting rod 706. The mounting member 5 drives the cutting module 6 to deflect clockwise together, thereby changing the inclination angle of the cutting module 6 in the vertical direction, so that the laser line coming out of the cutting module 6 is always perpendicular to the surface of the composite plate 101, thereby reducing the cutting energy consumption and improving the cutting quality of the composite plate 101.

[0034] During the relative sliding between the sliding housing 703 and the support member 702, due to the influence of the through holes on the deflection rod 704 on the flow of the hydraulic oil in the sliding housing 703, the relative sliding between the sliding housing 703 and the support member 702 is relatively slow. This provides sufficient time for the laser to cut the bent portion of the composite plate 101 (since there is a situation where the local material density at the bent portion of the composite plate 101 is too high, the cutting difficulty at this location is greater than that of other flat areas), thereby ensuring the normal progress of the cutting work.

[0035] As Figure 8 and Figure 9 shown, it further includes: a support mechanism disposed on the frame 1 for supporting the material; the support mechanism includes: a housing 901, which is a plurality of spaced apart ones, all fixedly connected to the frame 1, and the housing 901 is filled with a transmission medium; a sliding rod 902, the number of which is the same as the number of the housing 901, respectively slidably connected to adjacent housings 901, and the bottom of the sliding rod 902 is located in the middle of the adjacent housing 901 for providing a space for relative up and down sliding between the two. A fourth elastic element 903 is fixedly connected between the housing 901 and the adjacent sliding rod 902. An intermediate pipe 904 is connected between adjacent housings 901, and a solenoid valve is installed at the connection between the housing 901 and the intermediate pipe 904 for controlling their connection state.

[0036] In the above solution, the transmission medium in the housing 901 is hydraulic oil. Before cutting the composite plate 101, the staff places the composite plate 101 on a plurality of sliding rods 902. Since there are raised areas on the composite plate 101, some of the sliding rods 902 are not squeezed. The squeezed sliding rods 902 slide relative to the adjacent housing 901 and squeeze the hydraulic oil in the housing 901 into the housing 901 of the adjacent sliding rod 902 that is not squeezed. The sliding rods 902 in these housings 901 all move upward and contact the raised areas on the composite plate 101, thereby providing comprehensive support for the composite plate 101 and preventing the composite plate 101 from having bending stress under the action of gravity due to the lack of support in the raised areas, so as to avoid the phenomenon that the cut composite plate 101 is bent and reduce the cutting quality. After the composite plate 101 is placed, the staff closes the solenoid valve to keep the housing 901 and the adjacent sliding rod 902 relatively fixed, improve the stability during the subsequent cutting process, and further improve the cutting quality of the composite plate 101.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
