Description

Technical Field

[0001] This application relates to the field of honeycomb composite panel processing technology, and more specifically, to a longitudinal cutting device for honeycomb composite panel processing. Background Technology

[0002] Honeycomb composite panels, as a lightweight and high-strength sandwich structure material, have been widely used in aerospace, rail transportation, interior decoration, and other fields. They are typically composed of two thin, high-strength panels (such as aluminum or composite panels) bonded together with a honeycomb core material in the middle. In the subsequent processing of these panels, longitudinal cutting along their length is a common and crucial step.

[0003] Currently, the most commonly used longitudinal cutting devices in the industry are circular saw-based cutting equipment. During operation, a high-speed rotating circular saw blade descends to cut into the board, while the board is fed manually or mechanically to complete the cut. However, during the downward and cutting process, the saw blade lacks effective and stable clamping of the board on both sides of the cutting line. The honeycomb core material is easily torn and collapsed under the pulling force of the saw blade's rotation, resulting in a rough cut surface and core deformation, affecting the cutting quality and the strength of the finished product. In addition, panel debris and honeycomb core debris generated during the cutting process are scattered everywhere, not only polluting the working environment and endangering the health of operators, but also making subsequent cleanup cumbersome.

[0004] Therefore, this application proposes a longitudinal cutting device for processing honeycomb composite panels to solve the above-mentioned technical problems. Utility Model Content

[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] The purpose of this application is to address the shortcomings of the prior art by providing a longitudinal cutting device for processing honeycomb composite panels, thereby solving the problems of tearing of honeycomb core material, poor cut surface quality, and debris splashing that pollutes the working environment due to the lack of effective clamping during circular saw cutting in the prior art.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A honeycomb composite panel processing longitudinal cutting device includes a machine body, a processing table fixed on the upper end face of the machine body, a movable groove opened on the upper end face of the processing table, a longitudinally arranged support plate slidably installed in the movable groove, a longitudinal processing groove opened on the upper surface of the support plate, a frame erected above the processing table, a cylinder installed at the top of the frame, the shaft of the cylinder pointing vertically downward, and a cutting machine fixed thereon;

[0009] The lower end of the cutting machine is provided with a cutting tool, and the lower end of the cutting machine is also elastically provided with a horizontal limiting cover. The middle part of the limiting cover has a processing port for the cutting tool to pass through, and several horizontal rollers are rotatably installed at the bottom of the limiting cover.

[0010] Furthermore, a pusher plate is slidably mounted on the upper surface of the processing table, and the pusher plate is perpendicular to the processing groove in the horizontal direction.

[0011] Furthermore, a positioning bolt is provided at one end of the support plate, and the positioning bolt abuts against the side wall of the processing table to form a positioning fixation.

[0012] Furthermore, a transverse limiting groove is provided on the upper end face of the frame, the bottom of the cylinder is slidably installed in the limiting groove, the cylinder shaft passes vertically through the limiting groove, and the bottom edge of the cylinder is fixed to the upper end face of the frame with bolts.

[0013] Furthermore, the cutting tool is a disc cutter, and a motor is fixed in the middle of one side of the cutting machine, with the motor fixed to the axis of the cutting tool.

[0014] Furthermore, two guide posts are symmetrically fixed to the upper end face of the limiting cover. The guide posts vertically penetrate the bottom edge of the cutting machine, and an elastic element is also provided between the bottom of the cutting machine and the upper end face of the limiting cover.

[0015] Furthermore, a vacuum cleaner is installed inside the machine body, the pipe of the vacuum cleaner is fixed to the upper end face of the limiting cover, and the pipe of the vacuum cleaner is connected to the inside of the limiting cover.

[0016] Furthermore, several of the rollers are arranged laterally on the limiting cover relative to the travel direction of the honeycomb composite panel.

[0017] The beneficial effects of this application are as follows:

[0018] In the above scheme, the cutting machine is driven downward by a cylinder, so that the elastically set limit cover and the roller at the bottom press tightly against the surface of the plate under the action of the elastic element. In conjunction with the slidingly adjustable support plate and processing groove, it can form a stable and flexible clamping on the plate on both sides of the cutting line during the longitudinal cutting process, and allow the plate to feed smoothly. It can effectively suppress the vibration of the plate, and to a certain extent reduce the problem of the honeycomb core material being pulled and torn by the rotating blade. It is conducive to obtaining a flatter cut surface and a complete core, thus improving the cutting quality.

[0019] In the above solution, by connecting the vacuum cleaner's pipes to the inside of the limiting cover, it forms a partially enclosed space with the limiting cover at the cutting point. This allows for efficient suction of debris generated during cutting, collecting most of the dust and debris. This improves the working environment, reduces cleaning difficulty, and minimizes health hazards to workers.

[0020] In summary, this device not only alleviates the problems of easy core material damage and dust generation in traditional cutting methods, but also ensures operational flexibility and adaptability through designs such as sliding positioning of the support plate and lateral adjustment of the cutting head, resulting in good overall performance.

[0033] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Reference Figure 1-4 As shown, this utility model provides a longitudinal cutting device for processing honeycomb composite panels, including a body 1 for providing overall support and installation foundation. A horizontal processing table 2 is fixedly installed on the upper surface of the body 1, which serves as a platform for supporting the panels to be processed and installing related functional components. On the upper surface of the processing table 2, a long, narrow movable groove 201 is formed along its longitudinal direction (i.e., the predetermined feed direction of the honeycomb composite panel). A support plate 3 with a matching shape is slidably disposed within the movable groove 201. The upper surface of the support plate 3 can be kept substantially flush with the table surface of the processing table 2 to directly support the honeycomb composite panel. The support plate 3 can slide laterally along its width within the movable groove 201 to facilitate adjustment for different cutting positions and ensure support effectiveness.

[0035] To provide downward space for the cutting tool during cutting, a continuous machining groove 301 is formed on the upper surface of the support plate 3 along its longitudinal centerline. After the support plate 3 is slidably adjusted to the desired position, the positioning bolt 302 located at one end can be tightened to make the end of the bolt tightly abut against the side wall of the processing table 2, thereby firmly fixing the support plate 3 in the current position. To facilitate the alignment and longitudinal feeding of the sheet metal, a horizontally sliding pusher plate 202 is also provided on the upper surface of the processing table 2. The surface of the pusher plate 202 is perpendicular to the length direction of the support plate 3 and can serve as a lateral positioning reference and force application point for the sheet metal.

[0036] A portal frame 4 is mounted above the processing table 2. A limiting groove 401 is formed on the top crossbeam of the frame 4 along the horizontal direction (i.e., the horizontal direction perpendicular to the material feed direction). A cylinder 5, serving as a power source, is slidably mounted within this limiting groove 401 via a slider connected to its bottom, allowing the cylinder 5 to move laterally. Specifically, the air circuit system of the cylinder 5 can be composed of existing air sources, control valves, pipelines, and auxiliary components, without any specific limitations. The piston rod (i.e., the shaft) of the cylinder 5 passes vertically downward through the limiting groove 401. After the lateral position of the cylinder 5 and the subsequent cutting unit is adjusted by sliding, the bottom of the cylinder body of the cylinder 5 can be locked and fixed to the top of the frame 4 using bolts. A cutting machine 6 is fixedly mounted at the end of the piston rod of the cylinder 5. A drive motor 601 is fixed on one side of the cutting machine 6. The output shaft of the motor 601 is horizontally set and directly connected to the axis of the circular saw blade, which serves as the cutting tool 602, to drive it to rotate at high speed.

[0037] Below the cutting machine 6, a crucial clamping and protective component—a limiting cover 7—is installed. The limiting cover 7 is connected to the cutting machine 6 via an elastic guiding mechanism. Specifically, two vertically upward guide posts 8 are symmetrically fixed to the upper end face of the limiting cover 7, passing upward through guide holes corresponding to the bottom edge of the cutting machine 6. A compression spring, acting as an elastic element 801, is fitted onto the guide post 8 section between the bottom of the cutting machine 6 and the upper end face of the limiting cover 7, allowing the limiting cover 7 to elastically extend and retract relative to the cutting machine 6 in the vertical direction. A processing port 701 is opened in the middle of the limiting cover 7, through which the bottom of the high-speed rotating cutting tool 602 can pass precisely. At the bottom of the limiting cover 7, i.e., on the contact surface facing the sheet metal, multiple laterally arranged rollers 702 (i.e., the axial direction of the rollers 702 is perpendicular to the sheet metal feed direction) are rotatably mounted via bearings or other structures. When the limiting cover 7 presses against the surface of the plate, these rollers 702 can provide a stable clamping force and significantly reduce the frictional resistance when the plate moves longitudinally by rolling.

[0038] Meanwhile, to effectively handle cutting dust, a vacuum cleaner 9 is installed inside the machine body 1. The suction pipe of the vacuum cleaner 9 extends upward and is fixedly connected to the upper end face of the limiting cover 7, and the inside of the pipe communicates with the cavity enclosed by the limiting cover 7. When cutting is performed, the generated debris is confined in a local space below the limiting cover 7 and is then sucked away by the negative pressure generated by the vacuum cleaner 9.

[0039] In practice, the vacuum cleaner 9 can be any existing vacuuming equipment. The vacuum cleaner 9 can be fixedly installed on a shock-resistant bracket inside the body 1, and is driven by a high-power brushless motor to provide continuous and stable high negative pressure suction. The air inlet of the vacuum cleaner 9 is fixedly connected to the upper surface of the limiting cover 7 via a flexible anti-static vacuum hose and remains sealed.

[0040] Working principle: When using this honeycomb composite panel processing longitudinal cutting device, firstly, according to the width of the board to be cut and the predetermined cutting line position, slide and adjust the lateral position of the support plate 3 in the movable groove 201 so that the processing groove 301 is aligned with the expected cutting path. Then, tighten the positioning bolt 302 to fix it, place the honeycomb composite panel on the support plate 3, and make one side of it close to the push plate 202 for initial positioning.

[0041] Subsequently, the transverse sliding cylinder 5 and its connected entire cutting head assembly (including the cutting machine 6, the limiting cover 7, etc.) align the cutting plane of the cutting blade 602 with the cutting line on the sheet metal. After confirmation, the fixing bolts of the cylinder 5 are tightened. The vacuum cleaner 9 and the drive motor 601 are started, and the cutting blade 602 begins to rotate at high speed. The piston rod of the operating cylinder 5 is extended, driving the entire cutting machine 6 downwards. The cutting blade 602 first contacts and cuts into the sheet metal. As it continues to descend, the roller 702 at the bottom of the limiting cover 7, under the action of the elastic element 801, also presses tightly against the upper surface of the sheet metal, forming a stable and flexible pressure on both sides of the cutting line.

[0042] At this point, the operator or the automatic feeding mechanism pushes the pusher plate 202 or directly pushes the sheet material, causing it to move smoothly longitudinally along the support plate 3. The high-speed rotating cutting tool 602 then continuously completes the longitudinal cutting operation. Throughout the cutting process, the roller 702 rotates accordingly, and the negative pressure environment inside the limiting cover 7 continuously sucks in the cutting debris. After the cutting is completed, the piston rod of the cylinder 5 retracts, causing the cutting head to rise, allowing the processed sheet material to be removed. This device effectively improves cutting quality and the working environment through the coordinated operation of its various components.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
