Description

Technical Field

[0001] This invention belongs to the field of sheet metal cutting technology, and in particular relates to a fully automatic aluminum honeycomb sheet metal cutting device and its working method. Background Technology

[0002] Aluminum honeycomb composite panels are sandwich structures made of two layers of thin aluminum panels bonded together with a hollow aluminum honeycomb core. With their core advantages of being lightweight and high-strength, providing sound and heat insulation, excellent flatness, and strong impact resistance, they have been widely used in various fields such as building decoration, rail transportation, aerospace, shipbuilding, and new energy equipment, and the market demand for large-scale applications continues to increase. In the continuous production and deep processing of aluminum honeycomb composite panels, length cutting is the core process that determines the dimensional accuracy, structural integrity, and appearance quality of the finished product. The performance of the cutting process and equipment directly determines the final pass rate and applicable scenarios of the product.

[0003] Currently, most of the equipment used in the industry for shearing and processing aluminum honeycomb panels are general-purpose shearing machines and circular saws designed for solid metal sheets, or modified equipment that only makes simple structural adaptations. Their design logic and processing technology have not fully adapted to the heterogeneous sandwich structure characteristics of aluminum honeycomb panels, which consist of "thin panels + hollow thin-walled honeycomb cores". In actual production, there are many technical defects that are difficult to solve, and they cannot meet the requirements for high-precision, non-destructive, and continuous shearing and processing of aluminum honeycomb panels.

[0004] Firstly, most existing shearing equipment adopts a single-sided, unidirectional shearing processing method, which uses a single set of cutting tools to enter from one side of the plate and complete the cutting through the entire thickness of the plate in one go. In this cutting mode, the unidirectional cutting force is applied to one side throughout the entire cutting process. When the cutting does not penetrate the plate, the feed pressure of the tool and the cutting friction will form a peeling torque perpendicular to the bonding surface on the aluminum panel on the uncut side. This can easily cause the bonding interface between the panel and the honeycomb core to fail, leading to irreversible structural damage such as interlayer delamination, edge lifting, and interface delamination. This directly destroys the original structural strength and bonding reliability of the plate. At the same time, long-stroke unidirectional cutting will result in excessive tool overhang and reduced rigidity. Radial runout will be aggravated during the cutting process, generating continuous lateral extrusion force on the hollow honeycomb core. This will cause the honeycomb cell walls near the cut to collapse, compress, and tear. The thin aluminum panel on the cut surface of the plate is prone to defects such as chipping, flanging, and burrs due to the lack of rigid support. The quality of the upper and lower cuts is seriously uneven, requiring an additional manual secondary trimming process. The finished product qualification rate is greatly reduced. This defect is more prominent for ultra-thin plates, ultra-thick plates, and high-strength brazed honeycomb panels, making it unsuitable for the precision machining requirements of high-end fields such as aerospace and rail transportation.

[0005] Secondly, existing shearing equipment lacks a real-time online grinding control mechanism for saw blade wear. Saw blade edge grinding is mostly done manually after the fact, with manual grinding only performed when significant shearing quality defects occur. This approach cannot meet the specific needs of aluminum honeycomb panel shearing. The shearing process for aluminum honeycomb panels involves a high-frequency, intermittent cutting cycle of "dense aluminum panel - hollow honeycomb cavities." The saw blade edge is subjected to continuous alternating impacts, making it far more sensitive to edge sharpness than when cutting solid metal sheets. Even slight dulling of the edge can cause the cutting mode to shift from "sharp cutting" to "extrusion and tearing," leading to a series of problems such as honeycomb core collapse, panel delamination, edge chipping, and dimensional inaccuracies. In mass production, this can easily result in batch scrap. Furthermore, manual grinding requires interrupting the continuous production line, significantly reducing production line utilization and increasing overall production costs, failing to meet the continuous and stable mass production requirements for aluminum honeycomb panels.

[0006] Third, existing shearing equipment mostly uses a linear rigid pressure plate for localized clamping of the sheet metal. This method only allows for line contact clamping in a narrow area near the blade edge, and does not address the easily deformable structural characteristics of aluminum honeycomb panels by designing a full-area support and fixing mechanism. Under this clamping mode, the clamping force is concentrated in the linear area of ​​the blade edge, which can easily crush the thin-walled honeycomb core, causing localized indentations and irreversible plastic deformation of the sheet metal. At the same time, most areas of the sheet metal are suspended and unsupported, and the cutting impact force during the shearing process can easily cause the sheet metal to bend, warp, shift, and vibrate at high frequencies, leading to problems such as wavy cut surfaces, out-of-tolerance perpendicularity, and loss of dimensional accuracy. It is impossible to guarantee the flatness and stability of the sheet metal during the shearing process. Summary of the Invention

[0007] The purpose of this invention is to address the above-mentioned problems by providing a fully automatic aluminum honeycomb panel cutting device and its operating method.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an automatic aluminum honeycomb panel shearing device, comprising a base, two support plates symmetrically fixedly connected to the upper end of the base, the same mounting frame fixedly connected to the upper ends of the two support plates, and further comprising two sets of shearing and conveying components, two sets of shearing components, a pressing component and a PLC controller;

[0009] The two sets of shearing and transfer assemblies are fixed at the upper and lower ends of the mounting frame, and the moving end of the shearing and transfer assembly is fixedly connected to the shearing assembly.

[0010] The clamping assembly is fixed in the middle of the mounting frame and is positioned between the two sets of shearing assemblies;

[0011] The shearing assembly also contains a grinding assembly, and the grinding process of the shearing assembly is controlled by a PLC controller.

[0012] In the above-mentioned fully automatic aluminum honeycomb panel shearing device, the shearing and transfer assembly includes four symmetrically fixed electric push rods inserted into the mounting frame. The moving ends of two electric push rods are fixedly connected to the same fixed plate. Two symmetrically arranged transverse electric slide rails are fixed on the two fixed plates. The moving ends of the two transverse electric slide rails are fixedly connected to the same longitudinal electric slide rail. The moving end of the longitudinal electric slide rail is fixedly connected to the shearing assembly.

[0013] In the above-mentioned fully automatic aluminum honeycomb panel shearing device, the shearing assembly includes a connecting block fixed to the moving end of the longitudinal electric slide rail. Two connecting plates are symmetrically fixedly connected to the side of the connecting block away from the longitudinal electric slide rail, and electric shearing saw blades are fixedly connected to the side of the two connecting plates away from the connecting block.

[0014] In the aforementioned fully automatic aluminum honeycomb panel shearing device, the pressing assembly includes a support plate fixed in the middle of the inner wall of the mounting frame. Two mounting plates located on the upper side of the support plate are symmetrically fixed to the inner wall of the mounting frame. Two electric push rods are symmetrically fixedly inserted on the mounting plates. The moving ends of the four electric push rods are fixedly connected to the same pressing plate. The pressing plate is located on the upper side of the support plate. Multiple cutting grooves are correspondingly opened on the support plate and the pressing plate.

[0015] In the above-mentioned fully automatic aluminum honeycomb panel shearing device, the grinding assembly includes an electric push rod three fixedly inserted into the rear side of the electric shearing saw blade, and an arc-shaped grinding block is fixedly connected to the moving end of the electric push rod three. An arc-shaped grinding groove is formed on the inner side of the arc-shaped grinding block.

[0016] In the aforementioned fully automatic aluminum honeycomb panel shearing device, both the support plate and the pressing plate are hollow structures, and multiple negative pressure suction heads are sealed and movable on opposite sides. Multiple negative pressure holes are opened on the end sidewalls of the negative pressure suction heads. Multiple concealed grooves for embedding the negative pressure suction heads are opened on the sidewalls of both the support plate and the pressing plate. A guide plate is fixed to one end of the negative pressure suction head located inside the support plate and the pressing plate. Multiple guide rods are fixedly connected to the inner walls of both the support plate and the pressing plate. The guide plate and the guide rods are slidably sleeved together. Multiple extrusion springs sleeved on the outside of the guide rods are fixedly connected to the opposite side of the support plate and the pressing plate. The sidewalls of the support plate and the pressing plate are fixedly connected to the same negative pressure pipe, and a negative pressure pump is installed on the negative pressure pipe.

[0017] A method for operating a fully automatic aluminum honeycomb panel shearing device includes the following steps:

[0018] S1. Place the aluminum honeycomb panel to be cut into the clamping assembly and clamp it in place by the clamping assembly;

[0019] The S2.PLC controller controls the shearing and transfer assembly to drive the shearing assembly to the corresponding shearing position, and performs bidirectional synchronous shearing of the aluminum honeycomb panel to a fixed size through the shearing assembly.

[0020] The S3.PLC controller records the working time of the shearing component and, after the working time reaches a set threshold, grinds the shearing component to ensure that the sharpness of the shearing component meets the shearing requirements of the aluminum honeycomb panel.

[0021] In the above-mentioned working method of a fully automatic aluminum honeycomb panel shearing device, the pressing component in S1 provides an adsorption support force to the aluminum panel of the aluminum honeycomb panel, keeping the aluminum panel from deforming during the shearing process.

[0022] Compared with existing technologies, the advantages of this invention are as follows:

[0023] 1. Through the set base, support plate, mounting frame, shearing and transfer assembly, and shearing assembly, a double-sided synchronous shearing method is adopted. Two sets of cutting tools cut symmetrically and synchronously from the top and bottom of the plate, so that the bidirectional cutting forces are balanced and canceled out in the center area of ​​the plate thickness. This force mode will not form peeling force or tearing torque at the bonding interface between the upper and lower panels and the honeycomb core, fundamentally eliminating problems such as interlayer delamination, warping, and delamination. It can completely preserve the original structural strength and bonding reliability of the aluminum honeycomb panel, and significantly improve the structural integrity of the cut part and the product qualification rate.

[0024] 2. Through the set grinding components and PLC controller, the saw blade can be automatically and quickly ground online according to the actual wear level of the electric shearing saw blade, keeping the saw blade edge sharp in real time. Since aluminum honeycomb panels are sandwich structures with thin panels and hollow honeycomb cores, they are extremely sensitive to the sharpness of the saw blade. Timely and automatic maintenance of the edge sharpness can effectively avoid problems such as squeezing, pulling, honeycomb core collapse, panel delamination, and cut edge chipping caused by saw blade dulling, thereby significantly improving the shearing quality and dimensional accuracy, and better meeting the high-precision and non-destructive shearing processing requirements of aluminum honeycomb panels.

[0025] 3. By using the set-up clamping components, the aluminum honeycomb panel is designed with thin panels, hollow honeycomb cores, and easy deformation characteristics. During the shearing process, a vacuum adsorption support force is applied to the aluminum panel, which can make the entire panel be uniformly and stably adsorbed and fixed in the working position. This effectively avoids deformation problems such as panel bending, honeycomb core collapse, panel warping, and vibration displacement under the action of shearing force. It ensures the integrity of the panel structure from the root and significantly improves the shearing accuracy, cut quality and finished product qualification rate of the aluminum honeycomb panel.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0034] like Figures 1-6 As shown, an automatic aluminum honeycomb panel shearing device includes a base 1, two support plates 2 are symmetrically fixedly connected to the upper end of the base 1, and the same mounting frame 3 is fixedly connected to the upper end of the two support plates 2. It also includes two sets of shearing and conveying components 4, two sets of shearing components 5, a pressing component 6 and a PLC controller 7.

[0035] Two sets of shearing and transfer components 4 are fixed at the upper and lower ends of the mounting frame 3, and the moving end of the shearing and transfer component 4 is fixedly connected to the shearing component 5.

[0036] The shearing and transfer assembly 4 includes four symmetrically fixed electric push rods 41 that are inserted into the mounting frame 3. The moving ends of two electric push rods 41 are fixedly connected to the same fixed plate 42. Two symmetrically arranged transverse electric slide rails 43 are fixed on the two fixed plates 42. The moving ends of the two transverse electric slide rails 43 are fixedly connected to the same longitudinal electric slide rail 44. The moving end of the longitudinal electric slide rail 44 is fixedly connected to the shearing assembly 5.

[0037] The shearing assembly 5 includes a connecting block 51 fixed to the moving end of the longitudinal electric slide rail 44. Two connecting plates 52 are symmetrically fixed to the side of the connecting block 51 away from the longitudinal electric slide rail 44. An electric shearing saw blade 53 is fixedly connected to the side of the two connecting plates 52 away from the connecting block 51.

[0038] The clamping component 6 is fixed in the middle of the mounting frame 3 and is positioned between the two sets of shearing components 5;

[0039] The clamping assembly 6 includes a support plate 61 fixed in the middle of the inner wall of the mounting frame 3. Two mounting plates 62 are symmetrically fixed on the inner wall of the mounting frame 3, located above the support plate 61. Two electric push rods 63 are symmetrically fixed on the mounting plates 62. The moving ends of the four electric push rods 63 are fixedly connected to the same pressing plate 64. The pressing plate 64 is located above the support plate 61. Multiple cutting grooves 65 are correspondingly opened on the support plate 61 and the pressing plate 64.

[0040] Both the support plate 61 and the pressing plate 64 are hollow structures, and multiple negative pressure suction heads 66 are sealed and movable on opposite sides. Multiple negative pressure holes 67 are opened on the end side wall of the negative pressure suction head 66. Multiple concealed grooves 68 for embedding the negative pressure suction head 66 are opened on the side wall of both the support plate 61 and the pressing plate 64. A guide plate 69 is fixed to one end of the negative pressure suction head 66 located inside the support plate 61 and the pressing plate 64. Multiple guide rods 610 are fixedly connected to the inner wall of both the support plate 61 and the pressing plate 64. The guide plate 69 is slidably sleeved with the guide rods 610. Multiple extrusion springs 611 sleeved on the outside of the guide rods 610 are fixedly connected to the opposite side of the support plate 61 and the pressing plate 64 and the guide plate 69. The same negative pressure pipe 612 is fixedly connected to the side wall of the support plate 61 and the pressing plate 64. A negative pressure pump 613 is installed on the negative pressure pipe 612.

[0041] The shearing assembly 5 is also fixed with a grinding assembly 8. The grinding assembly 5 is controlled by the PLC controller 7 to perform grinding. The grinding assembly 8 includes an electric push rod 81 fixedly inserted into the rear side of the electric shearing saw blade 53. The moving end of the electric push rod 81 is fixedly connected to an arc-shaped grinding block 82. An arc-shaped grinding groove 83 is opened on the inner side of the arc-shaped grinding block 82.

[0042] The operating principle of this invention is described as follows: The aluminum honeycomb panel to be sheared is first placed on the support plate 61 for positioning. The PLC controller 7 controls the electric push rod 63 to push the pressing plate 64 toward the support plate 61, pressing and limiting the upper side of the aluminum honeycomb panel. The PLC controller 7 then controls the electric shearing saw blade 53 to work. The electric push rod 41 pushes the electric shearing saw blade 53 through the cutting groove 65 on the surface of the support plate 61 and the pressing plate 64 to contact the aluminum honeycomb panel. The transverse electric slide rail 43 can drive the electric shearing saw blade 53 to adjust the cutting position, thereby achieving different sizes of the aluminum honeycomb panel. In the shearing operation, the longitudinal electric slide rail 44 drives the electric shearing saw blade 53 to move along the cutting groove 65, realizing the rapid shearing of the entire aluminum honeycomb panel. The upper and lower electric shearing saw blades 53 perform shearing operations simultaneously, so that the bidirectional cutting forces are balanced and canceled out in the center area of ​​the panel thickness. This force mode will not form peeling force or tearing torque at the bonding interface between the upper and lower panels and the honeycomb core, fundamentally eliminating problems such as interlayer delamination, warping, and delamination. It can completely preserve the original structural strength and bonding reliability of the aluminum honeycomb panel, and significantly improve the structural integrity of the cut part and the product qualification rate.

[0043] The PLC controller 7 records the working time of the electric shearing saw blade 53. When the working time of the electric shearing saw blade 53 reaches the set threshold, the PLC controller 7 controls the shearing transfer assembly 4 to move the electric shearing saw blade 53 to the outermost position. The PLC controller 7 then controls the electric push rod 81 to push the arc-shaped grinding block 82 toward the electric shearing saw blade 53, so that the arc-shaped grinding groove 83 on the inner side of the arc-shaped grinding block 82 fits with the shearing end of the electric shearing saw blade 53. The PLC controller 7 controls the electric shearing saw blade 53 to rotate, using the arc-shaped grinding groove 83 to move the electric shearing saw blade 53. The cutting block 82 performs timely grinding on the electric shearing saw blade 53, which can automatically and quickly grind the saw blade online, keeping the saw blade edge sharp in real time. Since the aluminum honeycomb panel is a sandwich structure with a thin panel and a hollow honeycomb core, it is extremely sensitive to the sharpness of the saw blade. Timely and automatic maintenance of the edge sharpness can effectively avoid problems such as squeezing, pulling, honeycomb core collapse, panel delamination, and cut edge chipping caused by saw blade dulling, thereby significantly improving the shearing quality and dimensional accuracy, and better meeting the high-precision and non-destructive shearing processing requirements of aluminum honeycomb panels.

[0044] Furthermore, when the aluminum honeycomb panel is fixed by the support plate 61 and the pressing plate 64, the aluminum honeycomb panel will be pressed against the negative pressure suction head 66 on the support plate 61 and the pressing plate 64, thereby causing the negative pressure suction head 66 to be squeezed and move relative to it. The negative pressure suction head 66 enters the concealed groove 68, and the end of the negative pressure suction head 66 is in contact with the surface of the support plate 61 and the pressing plate 64. Moreover, one end of the squeezed and moved negative pressure suction head 66 will enter the interior of the support plate 61 and the pressing plate 64, thereby making the negative pressure hole 67 opened on the side wall of the end of the negative pressure suction head 66 connected with the support plate 61 and the pressing plate 64. During the actual shearing operation, the PLC The controller 7 controls the negative pressure pump 613 to work. The negative pressure pump 613, together with the negative pressure pipe 612, generates negative pressure suction force in the support plate 61 and the pressing plate 64. Then, through the negative pressure hole 67, it generates negative pressure suction force in the negative pressure suction head 66, so that the negative pressure suction head 66 provides an adsorption support force to the aluminum panel of the aluminum honeycomb panel. This allows the entire panel to be uniformly and stably adsorbed and fixed in the working position, effectively avoiding deformation problems such as panel bending, honeycomb core collapse, panel warping, and vibration displacement under shearing force. This ensures the integrity of the panel structure from the root and significantly improves the shearing accuracy, cut quality and finished product qualification rate of the aluminum honeycomb panel.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
