Description

Technical Field

[0001] The invention relates to the technical field of plate cutting, and in particular to a cutting device for producing composite plates. Background Art

[0002] Composite panels are new types of panels made of two or more different materials in a certain proportion and structure, mainly including metal-plastic composite panels, metal-ceramic composite panels, fiber-reinforced composite panels and honeycomb composite panels. Composite panels can be changed in strength and structure according to the requirements of the use scenario, so they are widely used in aerospace, architectural decoration, transportation, sports and leisure and other fields. Composite panels need to be cut accordingly according to the design dimensions after production. Existing cutting methods include laser cutting and mechanical cutting. Laser cutting is widely used because of its advantages of high precision and high degree of automation. However, when existing laser cutting equipment cuts composite panels with protrusions (folded protrusions), the laser line is always in the vertical direction, which leads to an increase in the "thickness" of the laser-cut composite panel, resulting in inadequate laser cutting, reduced cutting quality, and increased laser scattering and reflection, affecting the health of workers. Summary of the invention

[0003] In order to overcome the shortcomings mentioned in the above technical background, the present invention provides a cutting device for producing composite panels.

[0008] As a further preferred solution, a through hole is provided on the deflection rod for providing damping for the relative sliding between the sliding shell and the deflection rod.

[0010] As a further preferred solution, the length of the first deflection member is smaller than the length of the second deflection member, so that the second deflection member contacts the material first and the cutting module is deflected at the bend of the material.

[0011] As a further preferred scheme, it also includes: a supporting mechanism, which is arranged on the frame and is used to support the material; the supporting mechanism includes: a plurality of shells, which are distributed at intervals and are all fixedly connected to the frame, and the shells are filled with transmission medium; sliding rods, the number of which is the same as the number of the shells, which are respectively slidably connected to adjacent shells, a fourth elastic element is fixedly connected between the shells and the adjacent sliding rods, and an intermediate tube is connected between the adjacent shells.

[0012] As a further preferred solution, the bottom of the sliding rod is located in the middle of the adjacent housing, so that there is space between the two for relative upward and downward sliding.

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

[0014] Compared with the prior art, the present invention has at least the following advantages: the present invention changes the deflection angle of the cutting module so that the laser line emitted from the cutting module is always perpendicular to the surface of the composite plate during the cutting process, maximizes the use of laser energy for cutting, reduces invalid energy loss, and reduces the total distance the laser passes through the composite plate, preventing the increase in the vertical "thickness" of the shape-changing area of ​​the composite plate, which causes the laser cutting to be inadequate and reduces the cutting quality, and reduces the laser scattering and reflection, thereby improving the protection of workers; the damping of the transmission medium flowing through the through hole on the deflection rod is used to reduce the deflection speed of the cutting module, thereby providing sufficient time for the laser to cut the bending part of the composite plate to ensure that the cutting work is carried out normally; the composite plate is fully supported by the sliding rod that moves up and down to prevent the raised area on the composite plate from having no support and bending stress under the action of gravity, thereby causing the composite plate to bend after cutting, thereby reducing the cutting quality.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.

[0018] like Figure 1-Figure 3 and Figure 6 As shown, an embodiment of the present invention is proposed, which provides a cutting device for composite board production, which is used for adaptive cutting of the plate to solve the problem that the laser cutting line is not perpendicular to the plane of the plate in the existing cutting process, thereby causing uneven incisions and burrs, and at the same time reducing the distance that the laser penetrates the plate, thereby reducing the loss of invalid energy, including: a frame 1; a moving module 2, installed on the frame 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 member 5, rotatably connected to the mounting frame 4; a cutting module 6, installed on the mounting member 5; the moving module 2 and the lifting module 3 are respectively used to make the cutting module 6 move horizontally and vertically, so that the cutting module 6 can cut the material; a deflection mechanism is arranged on the mounting frame 4, which is used to detect the inclination state of the material cutting area; a limit mechanism is arranged on the mounting frame 4, which is used to make the mounting member 5 and the mounting frame 4 rotate relative to each other.

[0019] In the above scheme, 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 plate 101, so as to ensure the distance between the cutting module 6 and the surface of the composite plate 101, ensure that the laser focus point accurately falls on the surface of the composite plate 101, and achieve precise cutting, thereby improving the cutting quality of the composite plate 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 plate 101. During the process, the mounting frame 4 and the mounting member 5 are relatively rotated by the deflection mechanism and the limiting mechanism, and the deflection angle of the cutting module 6 is changed, so that the laser line from the cutting module 6 is always perpendicular to the surface of the composite plate 101 during the cutting process, and the laser energy is used to the maximum extent for cutting, and the invalid energy loss is reduced. At the same time, the total distance of the laser passing through the composite plate 101 is reduced, and the vertical "thickness" of the shape change area of ​​the composite plate 101 is prevented from increasing, resulting in inadequate laser cutting and reduced cutting quality, and reducing laser scattering and reflection, thereby improving the protection of workers.

[0020] like Figure 2-Figure 5 As shown, the deflection mechanism includes: a first deflection member 701, which is rotatably connected to the mounting frame 4, and a spring is fixedly connected between the first deflection member 701 and the mounting frame 4, which is used to reset the first deflection member 701; a support member 702, which is fixedly connected to the mounting frame 4; a sliding shell 703, which is slidably connected to the support member 702, and the sliding shell 703 is filled with a transmission medium; a deflection rod 704, which is fixedly connected to the first deflection member 701, and the deflection rod 704 is slidably connected to the sliding shell 703, and the deflection rod 704 has an arc area The sliding shell 703 is a part of a circular 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 frame 4 are on the same horizontal line. A through hole is provided on the deflection rod 704 to provide 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 is fixedly connected between the mounting member 5 and the sliding shell 703.

[0021] In the above scheme, the first deflection member 701 is tilted and is used to compress the first elastic element 705 during the process of contacting the composite plate 101. The transmission medium in the sliding shell 703 is hydraulic oil. The first elastic element 705 is a spring, which is used to apply pressure to the sliding shell 703, so that the sliding shell 703 and the support member 702 slide relative to each other. When the composite plate 101 needs to be cut, the lifting module 3 drives the mounting frame 4 and the parts thereon to move downward together. After the first deflection member 701 moves downward to contact the composite plate 101, the first deflection member 701 starts to deflect clockwise (such as Figure 5 Taking the direction shown as an example), the first deflection member 701 compresses the spring, and the first deflection member 701 drives the deflection rod 704 to deflect clockwise. The deflection rod 704 is compressed by the first elastic element 705 and drives the sliding shell 703 to deflect clockwise. 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 until the cutting module 6 moves downward to the height of the to-be-determined cutting position and stops moving (and stops deflecting clockwise at the same time). At this time, the cutting module 6 is perpendicular to the composite plate 101, and the limiting mechanism limits (fixes) the sliding shell 703, and then starts cutting the composite plate 101.

[0022] During the cutting process (taking cutting of the composite plate 101 from left to right as an example), when the first deflection member 701 moves to the right until it contacts the protrusion on the composite plate 101, the first deflection member 701 further deflects clockwise. Since the sliding shell 703 is limited by the limiting mechanism at this time, the deflection rod 704 slides relative to the sliding shell 703, and the first elastic element 705 is compressed. During the process, the hydraulic oil in the lower part of the sliding shell 703 moves to the upper part through the through hole on the deflection rod 704.

[0023] like Figure 3-Figure 7 As shown, the limiting mechanism includes: a moving frame 801, which is 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 deflection member 803, which is rotatably connected to the mounting frame 4, and the length of the first deflection member 701 is less than the length of the second deflection member 803, so that the second deflection member 803 contacts the material first, and the cutting module 6 is deflected at the bending part of the composite plate 101, and a third elastic element 804 is fixedly connected between the second deflection member 803 and the mounting frame 4; a limiting rod 805, which is fixedly connected to the second deflection member 803, and the limiting rod 805 is limitedly matched with the moving frame 801; a limiting column 806, which is fixedly connected to the moving frame 801, and the sliding shell 703 is provided with spaced limiting grooves 807, and the limiting grooves 807 are limitedly matched with the limiting column 806.

[0024] In the above scheme, 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 movable frame 801. The third elastic element 804 is a spring, which is used to reset the second deflection member 803 to the movable frame 801 for limited extrusion. There are two limit rods 805 distributed up and down, which are used to make the second deflection member 803 limit and extrude the movable frame 801 during different rotation processes. The lower limit rod 805 is initially in a state of limited extrusion cooperation with the movable frame 801. The area where the movable frame 801 and the limit rod 805 are limited is vertical. During the downward movement of the mounting frame 4, the mounting frame 4 drives the second deflection member 803 to move downward together. After the second deflection member 803 contacts the composite plate 101 during the downward movement, the second deflection member 803 begins to deflect counterclockwise (such as Figure 3 The second deflection member 803 is rotated counterclockwise to a horizontal position (the cutting module 6 is perpendicular to the composite board 101 and is in a state to be cut). At this time, both limit rods 805 are in contact with the moving frame 801 and neither of them squeezes and limits the moving frame 801.

[0025] During the cutting process of the composite plate 101 from left to right, when the second deflection member 803 contacts the protrusion on the composite plate 101, the second deflection member 803 further deflects counterclockwise, and the second deflection member 803 drives the two limiting rods 805 to deflect counterclockwise together, and the upper limiting rod 805 begins to squeeze the movable frame 801 to the left, and the movable frame 801 moves to the left and stretches the second elastic element 802, and the movable frame 801 drives the limiting column 806 to move to the left together, and the limiting column 806 gradually disengages from the limiting groove 807 and gradually loses the limiting position on the sliding shell 703, and then 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 to Figure 5 Taking the direction shown as an example), the sliding shell 703 drives the mounting member 5 to deflect clockwise through the connecting rod 706, and the mounting member 5 drives the cutting module 6 to deflect clockwise, thereby changing the inclination angle of the cutting module 6 in the vertical direction, so that the laser line emitted from 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.

[0026] During the relative sliding between the sliding shell 703 and the support member 702, since the flow of the hydraulic oil in the sliding shell 703 is affected by the through hole on the deflection rod 704, the relative sliding between the sliding shell 703 and the support member 702 is relatively slow, thereby providing sufficient time for the laser to cut the bending part of the composite plate 101 (since there is a local excessive material density at the bending part of the composite plate 101, the cutting difficulty there is greater than that of other flat areas), thereby ensuring the normal progress of the cutting work.

[0027] like Figure 8 and Fig. 9 As shown, it also includes: a supporting mechanism, which is arranged on the frame 1 and is used to support the material; the supporting mechanism includes: a plurality of shells 901, which are distributed at intervals and are fixedly connected to the frame 1, and the shells 901 are filled with a transmission medium; sliding rods 902, the number of which is the same as the number of shells 901, are respectively slidably connected to adjacent shells 901, and the bottom of the sliding rod 902 is located in the middle of the adjacent shells 901, which is used to allow space for relative upward and downward sliding between the two, a fourth elastic element 903 is fixedly connected between the shell 901 and the adjacent sliding rod 902, and an intermediate pipe 904 is connected between the adjacent shells 901, and an electromagnetic valve is installed at the connection between the shell 901 and the intermediate pipe 904 to control the connection state between the two.

[0028] In the above scheme, 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 the composite plate 101 has a raised area, some sliding rods 902 are not squeezed. The squeezed sliding rods 902 slide relative to the adjacent housing 901, and the hydraulic oil in the housing 901 is squeezed into the adjacent housing 901 on which the sliding rods 902 are not squeezed through the adjacent intermediate pipe 904. The sliding rods 902 in these housings 901 are 2 all move upward and contact with the raised area on the composite plate 101, so as to fully support the composite plate 101, and prevent the raised area on the composite plate 101 from having no support and having bending stress under the action of gravity, thereby causing the composite plate 101 to bend after cutting, reducing 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, thereby improving the stability in the subsequent cutting process, and thus improving the cutting quality of the composite plate 101.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
