Description

Technical Field

[0001] This invention belongs to the field of metal cutting technology, specifically relating to a fully automatic metal honeycomb core automatic layout and cutting equipment. Background Technology

[0002] Metal honeycomb core panels, as a new type of structural material that is lightweight, sound-insulating, heat-insulating, and shock-absorbing, are characterized by a porous, thin-walled honeycomb grid structure. However, existing cutting equipment for metal honeycomb core panels has many shortcomings, making it difficult to meet the demands of fully automated, high-precision industrial processing. First, existing equipment mostly adopts a cutting mode with a fixed saw blade and a moving workpiece. After cutting, the saw blade is prone to interference with the workpiece, so the workpiece can only be fed in a single linear motion, which prevents the plate from rotating for secondary layout and cutting, limiting layout flexibility. Second, existing positioning and clamping mechanisms are mostly general flat plate designs that do not take into account the porous thin-walled structure of metal honeycomb cores. During clamping, the internal core cells are easily crushed, and some equipment only uses clamping in one direction, making it difficult to achieve stable fixation of the plate. The plate is prone to slippage during the cutting process, affecting cutting accuracy. Third, the degree of automation is low: existing equipment mostly adopts segmented control, and manual intervention is required between processes such as layout, feeding, positioning, cutting, and turning, making it impossible to achieve fully closed-loop automated operation. Summary of the Invention

[0003] To address the aforementioned shortcomings of existing technologies, the present invention aims to provide a fully automatic metal honeycomb core automatic layout and cutting device. Designed specifically for the thin-walled, porous characteristics of metal honeycomb cores, this invention solves the technical problems of existing cutting equipment, such as difficulty in rotating workpieces for flexible layout, easy crushing of internal core cells by the clamping mechanism, slippage of the sheet material during cutting, and low automation. The specific technical solution is as follows: A fully automatic metal honeycomb core automatic layout and cutting equipment includes a frame assembly, a workpiece feeding mechanism, a workpiece positioning part, a workpiece clamping structure, a circular saw blade cutting and moving component, a workpiece rotation mechanism, and a CNC control system. These systems work together to achieve fully automatic layout and cutting of metal honeycomb core panels. The frame assembly serves as the overall support structure of the equipment, employing a rigid frame welded from high-strength steel to ensure stability during operation and prevent vibration from affecting cutting accuracy. A horizontal worktable is installed on top of the frame assembly, covered with a special anti-slip damping layer for honeycomb cores. This effectively prevents slippage of the metal honeycomb core panels during feeding, cutting, and rotation, while also preventing scratches on the panel surface. Transverse slide rails are provided on both sides of the worktable along the Y-axis, and the workpiece feeding mechanism is mounted on these transverse slide rails. The mechanism is used to achieve continuous step-feeding of metal honeycomb core panels. It includes a servo feed motor, a ball screw pair, a feed slide, and an electrically driven moving slider. The drive shaft of the servo feed motor is coaxially connected to the lead screw of the ball screw pair. Two nuts are installed on the lead screw, and a moving block is fixedly connected between the nuts. The servo feed motor drives the ball screw pair to rotate, which in turn drives the moving block to move through the nuts. This synchronously drives the feed slide to move smoothly along the transverse slide rail. A vertical plate is fixedly welded to the top surface of the moving block, and a moving crossbeam is installed between the vertical plates. The side of the moving block is connected to the feed slide, and the feed slide is slidably engaged on the transverse slide rail. The electrically driven moving slider is slidably installed on the rails on the upper and lower sides of the rear end face of the moving crossbeam. A longitudinal connecting frame is fastened to the back of the electrically driven moving slider by a bolt assembly. A longitudinal slide rail is installed on the longitudinal connecting frame. The workpiece positioning unit is used to collect data such as the position and thickness of the metal honeycomb core sheet in real time, providing positioning feedback to the CNC control system and achieving precise positioning of the sheet. The workpiece positioning unit includes a photoelectric positioning sensor, a laser rangefinder, and a corner positioning template. The photoelectric positioning sensor is installed on the top of the moving block, the laser rangefinder is installed on the bottom of the lifting moving block, and the corner positioning template is installed along the X-axis on the rear side of the top surface of the worktable. The photoelectric positioning sensor measures the workpiece feed distance to ensure accurate cutting dimensions. The laser rangefinder measures the workpiece thickness and automatically adjusts the cutting depth of the circular saw blade and the height of the lifting moving block. Data collected by each sensor is transmitted to the CNC control system in real time, forming a closed-loop control to ensure positioning accuracy. The corner positioning template contains internal... Clamping rods are installed on both the front and rear sides. A rubber block is installed on the right end of the clamping rods. A light-sensitive strip is installed on the right end face of the corner positioning mold and is connected to the built-in photoelectric sensor. The built-in photoelectric sensor is connected to the equipment control terminal. The photoelectric sensor is used to detect the cutting length and the position of the circular saw blade. A telescopic rod is installed on the rear end face of the corner positioning mold. A fixing block is connected to the fixed end of the telescopic rod. The fixing block is fixedly installed on the rear side of the top surface of the worktable, and the clamping rod passes through the interior of the fixing block. A limit nut is installed on the left end of the clamping rod. When the control terminal sends a start command through the electronic control element, the telescopic rod is activated through the circuit to extend, pushing the corner positioning mold to the right. The photoelectric sensor, together with the workpiece clamping structure, can accurately cut metal honeycomb cores of specified sizes. The rubber block on the right end of the clamping rod can protect the honeycomb core from excessive compression.

[0004] In some embodiments, the workpiece clamping structure includes a lifting moving block and a side-top clamping frame. The right side of the lifting moving block is mounted to the longitudinal slide rail via an electrically driven moving block mounted on the longitudinal slide rail. A connecting rod is snapped into the inside of the lifting moving block, and a slot is formed at the bottom of the connecting rod. Two slide grooves are formed at the bottom of the lifting moving block, and adjusting rings are respectively fastened to the inside of the slide grooves by nuts. A connecting plate above the adjusting ring has a through hole and is snapped into the inside of the slide groove. A laser rangefinder is mounted on one adjusting ring, and the side-top clamping frame is mounted on the other adjusting ring. The height of the laser rangefinder and the clamping frame is consistent. The top of the side-top clamping frame is connected to the bottom of the connecting rod by a pin. A downward pressure head is provided at the top of the side-top clamping frame, and a side pressure head is provided at the bottom of the side-top clamping frame. The device is equipped with a vacuum suction cup and has grooves on its bottom surface. The groove structure matches the honeycomb core structure to be cut. The grooves can press down and clamp the unsealed honeycomb core panel for feeding and cutting. At the same time, it can distribute the clamping pressure of the sealed honeycomb core panel to the solid area of ​​the panel, avoiding excessive local pressure that could crush the core cell. The vacuum suction cup inside the pressure head can adsorb the sealed honeycomb core panel. Both the side pressure head and the pressure head are made of flexible polyurethane material, which can clamp the panel from the side and top. The side pressure head only contacts the side of the panel, which can protect the side and top surface of the panel and prevent edge chipping or core cell collapse. The suction force of the vacuum suction cup can be adjusted according to the moving height of the lifting block to assist clamping, improve the stability of the honeycomb core clamping, and prevent the panel from slipping during the cutting process.

[0005] In some embodiments, the circular saw blade cutting moving component is used to achieve precise cutting of metal honeycomb core panels, and has follow-up cutting and active avoidance functions. The circular saw blade cutting moving component includes a circular saw blade, a high-speed spindle motor, a monorail cylinder, a transverse slider, and a chip suction component. The circular saw blade is an ultra-thin carbide saw blade specifically for metal honeycomb cores. The saw blade is thin and has a narrow kerf. The tooth shape adopts an anti-chipping design, which can effectively reduce chipping and slag inclusion during the cutting process, ensuring a smooth and flat cut surface. The high-speed spindle motor drives the circular saw blade at high speed. The rotation speed is adjusted by outputting a speed command based on the calculation results of the material and thickness information of the sheet metal received from the equipment control terminal. A rectangular plate is fixedly connected to the external fixed tube of the monorail cylinder. The rectangular plate is connected to the top surface of the transverse slider. The transverse slider is slidably engaged with a fixed slide rail on the left side of the top surface of the worktable. A guide rod is installed inside the transverse slider, and a roller is installed at the bottom of the guide rod. The roller slides in a groove opened on the left side of the top surface of the worktable. The guide rod is used to achieve synchronous sliding of the two sets of transverse sliders. The moving end of the monorail cylinder... A fixed support plate is connected to the workpiece. A guide rod runs through the interior of the support plate, ensuring its straight up-and-down movement and guaranteeing a straight cut by the circular saw blade, rather than the traditional oscillating arc-shaped cut. This results in more precise cutting dimensions. A high-speed spindle motor is mounted on the support plate, and a monorail cylinder drives the circular saw blade to rise and fall along the Z-axis, allowing it to descend to the workpiece surface for follow-up cutting. The cutting depth is automatically adjusted based on data from a laser rangefinder and a photoelectric sensor built into the corner positioning template. After cutting, the monorail cylinder drives the circular saw blade to rise rapidly, while a horizontal slider moves the entire blade to the side, completely separating it from the workpiece area. This proactive avoidance provides interference-free space for the rotation and secondary positioning of the workpiece, preventing collision damage between the saw blade and the workpiece. A debris extraction unit connects to a dust pump via a suction pipe. The dust pump is installed inside a dust collection box, located on the top left rear end of the worktable. The debris extraction unit continuously extracts chips generated during cutting, preventing them from entering the honeycomb core and ensuring cutting quality and equipment cleanliness.

[0006] In some embodiments, the workpiece rotation mechanism is used to drive the metal honeycomb core sheet to rotate precisely. Combined with the layout scheme of the CNC system, it enables fully automatic layout and cutting of complex graphics in multiple directions. The workpiece rotation mechanism includes a rotary drive motor, a slewing bearing, and a rotary table. The rotary drive motor is a DD direct drive motor, characterized by stable speed and high positioning accuracy. The slewing bearing is connected between the rotary drive motor and the rotary table to increase the load on the rotary table and drive it to rotate smoothly. The rotary table is installed in the worktable surface, and its top surface is flush with the top surface of the worktable surface. The rotary drive motor can drive the clamped metal honeycomb core sheet to rotate precisely at any angle from 0 to 360 degrees, with a rotation positioning accuracy of up to 0.01. An angle encoder is installed beside the rotary drive motor to collect the rotation angle data of the rotary table in real time and feed it back to the CNC control system to achieve closed-loop control of the rotation angle, ensuring rotation accuracy. The CNC control system can automatically calculate the rotation angle after each cut according to the preset layout scheme and drive the rotary table to rotate to the specified angle, preparing for the next cut.

[0007] In some embodiments, the CNC control system is the core control unit of the equipment, employing a combination of an industrial PLC controller and a touch screen, and incorporating fully automatic layout software to achieve automated control and operation of the entire equipment process. The CNC control system can import CAD layout drawings or manually input parameters such as cutting dimensions, rotation angles, and feed steps, automatically planning cutting paths and layout schemes; it receives feedback data in real time from the workpiece feeding mechanism, workpiece positioning part, workpiece rotation mechanism, and circular saw blade cutting moving component, and implements closed-loop control to ensure the coordinated work of each system, guaranteeing cutting accuracy and smooth process; it displays the equipment's operating status and cutting progress in real time, and automatically issues alarm signals and records fault information when the equipment experiences positioning deviations, clamping abnormalities, saw blade wear, or other faults, facilitating maintenance; it can store multiple layout schemes and processing parameters for easy recall during subsequent processing of similar workpieces, improving processing efficiency.

[0008] In some embodiments, a cutting clearance groove is provided inside the worktable corresponding to the cutting position of the circular saw blade, providing space for the lifting and cutting of the circular saw blade and avoiding interference between the saw blade and the worktable; a servo drive mounting base is provided on the side of the frame assembly to fix the servo feed motor of the workpiece feeding mechanism and ensure the installation accuracy of each component.

[0009] In some embodiments, a cutting method for a fully automatic metal honeycomb core automatic layout and cutting device is characterized by comprising the following steps: S1. Loading: Place the metal honeycomb core panel in the designated position on the machine frame worktable, start the equipment, and initialize the CNC system; S2. Automatic feed: The workpiece clamping structure clamps the solid frame and top surface of the plate and feeds the plate to the initial cutting position according to the preset step distance. S3. Precision positioning: The sensors in the workpiece positioning unit collect the position and thickness data of the sheet material in real time and feed them back to the CNC control system. The CNC control system controls the sheet material to abut against the corner positioning template to achieve initial precise positioning. S4. Adaptive clamping: The CNC control system controls the movement of the workpiece clamping structure. The lifting moving block and the side top clamping frame work together to fix the plate material from three dimensions with the corner positioning template, ensuring stable clamping without damaging the core. S5. Follow-up cutting: The circular saw blade cutting moving component is started, the high-speed spindle motor drives the circular saw blade to rotate, the monorail cylinder drives the saw blade to descend to the workpiece surface, the transverse slider drives the saw blade to follow up and cut along the preset path, and the chip suction component works synchronously. S6. Saw blade avoidance: After a single cut is completed, the single-rail cylinder drives the saw blade to rise rapidly, and the horizontal sliding block drives the saw blade to move to the side, completely away from the workpiece area, to avoid interference with the movement of the sheet metal. S7. Rotary Layout: The CNC control system automatically calculates the rotation angle according to the preset layout scheme, drives the rotary table to rotate the board to the angle of the next cut, and the angle encoder provides real-time feedback of the rotation angle to ensure accurate rotation. S8. Secondary positioning and cutting: The workpiece positioning part repositions the plate, the workpiece clamping structure re-clamps and fixes it, and steps S5-S7 are repeated for the next cutting. S9. Repeat the above steps until the entire metal honeycomb core panel has completed all cutting processes according to the preset layout scheme. The equipment will then stop automatically, achieving fully automatic layout and cutting.

[0010] This invention provides a fully automatic metal honeycomb core automatic layout and cutting device, which has the following beneficial effects: This invention is adapted to the characteristics of metal honeycomb cores. The specially designed workpiece clamping structure acts only on the solid area of ​​the board, effectively avoiding problems such as core cell crushing, edge chipping, and board deformation. The special ultra-thin circular saw blade and anti-chipping tooth design, together with the chip suction system, ensure that the cut surface is flat and smooth, without slag or scratches.

[0011] In addition, the circular saw blade adopts a movement mode of cylinder-driven lifting and horizontal sliding block movement. During cutting, the saw blade descends and cuts according to the workpiece requirements. After cutting, it actively moves away to avoid interference caused by the fixed saw blade of the existing equipment. It can realize layout cutting at any angle of 360 degrees and is suitable for processing complex graphics.

[0012] In addition, the integrated fully automatic typesetting software and closed-loop control system realize fully automated operation from feeding, positioning, clamping, cutting, avoidance, rotation to repositioning, without manual intervention. Servo drive and high-precision positioning and rotation structure enable the equipment to achieve millimeter-level positioning accuracy and even higher rotation accuracy, and the processing efficiency is greatly improved compared with traditional equipment.

[0013] In addition, the equipment can adjust parameters such as clamping force, cutting speed, and feed step distance according to metal honeycomb core panels of different thicknesses and materials, adapting to the processing needs of various specifications of workpieces, making it more versatile and practical for widespread application.

It can store multiple layout schemes and processing parameters for easy recall for subsequent processing of similar workpieces, thereby improving processing efficiency.

[0025] In this embodiment, a cutting clearance groove 101 is provided inside the worktable 11 corresponding to the cutting position of the circular saw blade, providing space for the lifting and cutting of the circular saw blade and avoiding interference between the saw blade and the worktable 11; a servo drive mounting base is provided on the side of the frame assembly 1 to fix the servo feed motor 21 of the workpiece feed mechanism 2 and ensure the installation accuracy of each component.

[0026] The working process of the device in this embodiment is as follows: The metal honeycomb core panel is placed on the workbench 11, the preset layout CAD drawing is imported, and the equipment is started; the workpiece feeding mechanism 2 feeds the panel to the initial cutting position; the sensors of the workpiece positioning part 3 collect the position data of the panel, and control the panel to abut against the corner positioning template 33, with a positioning accuracy of 0.01mm; the workpiece clamping structure 4 is activated, the lifting moving block 41 drives the side top clamping frame 42 to clamp the panel laterally and on the top surface, and the vacuum suction cup adsorbs and fixes it; the circular saw blade cutting moving component 5 is activated, the high-speed spindle motor 52 drives the circular saw blade 51 to rotate, the monorail cylinder 53 drives the saw blade to descend to the surface of the panel, and the transverse sliding block 5... 4. The drive saw blade cuts along the first path, and the chip suction component 55 works simultaneously. After the first path is cut, the monorail cylinder 53 drives the saw blade to rise 50mm, and the horizontal sliding block 54 drives the saw blade to move 200mm to the side to avoid collision. The CNC control system 7 calculates the rotation angle and drives the rotary table 63 to rotate the plate to the set angle. The angle encoder 64 provides feedback on the rotation angle. After repositioning and clamping, the cutting process is repeated to complete the second path cutting. The plate is rotated 90 degrees again to complete the third path cutting. After all cutting is completed, the clamping mechanism is released, and the equipment sends a completion signal to achieve fully automatic layout and cutting.
