Description

Technical Field

[0001] This invention belongs to the field of laser cutting equipment technology, and particularly relates to a multi-station flat cutting machine. Background Technology

[0002] In the field of laser processing equipment technology, irregularly shaped metal tubes and aluminum profiles are widely used in many industries such as leisure products, furniture hardware, automotive parts and precision machinery manufacturing due to their unique structural advantages. These workpieces often need to be processed by cutting the end planes or bevels to meet assembly and use requirements.

[0003] Currently, there are two main processing methods in the industry for cutting irregularly shaped metal tubes and aluminum profiles, but both have significant drawbacks. One method uses traditional laser tube cutting machines. Due to the irregular cross-sectional shape of irregularly shaped tubes, the clamping and positioning structure of existing laser tube cutting machines is difficult to adapt, failing to provide a stable positioning reference for irregularly shaped tubes. This results in poor cutting accuracy, low product consistency, and difficulty in meeting high-precision processing requirements. The other method uses stamping or manual processing. Stamping is only suitable for irregularly shaped tubes of specific specifications, has poor versatility, and suffers from high mold wear and replacement costs. Manual processing is not only extremely inefficient and labor-intensive, but also highly dependent on the skill level of the operator, resulting in large fluctuations in processing quality and making it impossible to achieve standardized mass production.

[0004] Meanwhile, while some existing multi-station cutting equipment attempts to improve efficiency by increasing the number of stations, it suffers from unreasonable structural design issues: First, the station layout lacks coordination, with loading and unloading operations interfering with the cutting operation. Loading and unloading can only be carried out after the cutting is completed, resulting in long idle times and low utilization rates. Second, the clamping and material support components do not match well enough, making it impossible to flexibly adjust according to material specifications. This results in poor adaptability and a lack of dynamic correction mechanisms for positional deviations during material processing, making it prone to cutting deviations due to slight material displacement or fluctuations in clamping force. Third, for thin-walled or soft shaped pipes, existing clamping structures often cause pipe deformation due to excessive clamping force or loosening of the material during processing due to insufficient clamping force, further affecting processing quality. In addition, waste collection and disposal methods are cumbersome, requiring additional manual cleaning and increasing production auxiliary costs.

[0005] Therefore, we specially designed a multi-station flat cutting machine. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a multi-station flat cutting machine that achieves stable clamping and dynamic compensation of clamping force.

[0007] In view of the above, the present invention provides a multi-station flat cutting machine, including a frame, a first slide table disposed on the frame, a laser cutting device disposed on the first slide table, the laser cutting device being connected to a main unit, the main unit being disposed on one side of the frame, and further comprising: A fixed clamp is mounted on a frame and includes a housing and a first clamping unit. The clamping module includes a second slide and clamping components. The second slide is mounted on the frame, and multiple clamping components are mounted on the second slide and positioned on both sides of the fixed clamping base. The material support assembly includes a third slide and a material support frame. The third slide is mounted on the frame, and the material support frame is located between the fixed clamp and the clamping assembly and is connected to the third slide. The material support assembly supports the material upward. The dynamic compensation module is installed on the clamping assembly and the material support frame and is electrically connected to the host. The dynamic compensation module dynamically monitors the material and controls the movement of the clamping assembly and the material support assembly through the host. The material is held in place by the material support assembly between the clamping assembly and the fixed clamp.

[0008] In this technical solution, the four-station flat cutting machine adapts to various irregular pipe materials through multi-component collaboration and dynamic compensation, achieving high-precision and stable clamping and cutting, improving processing efficiency and consistency, and reducing material deformation and labor costs.

[0009] In the above technical solution, the clamping component further includes: A first slide block is connected to a second slide table. A second clamping unit is provided on the first slide block. The second clamping unit has the same structure as the first clamping unit. The second slide is equipped with a first telescopic cylinder, and the movable end of the first telescopic cylinder is connected to the first slide. The first telescopic cylinder applies a continuous force to the first slide block, and forces the second clamping unit to continuously clamp the material.

[0010] In this technical solution, the clamping assembly uses a first telescopic cylinder to continuously apply force, and is paired with a second clamping unit identical to the first clamping unit to achieve stable clamping of materials, ensuring no displacement during processing, adapting to irregularly shaped pipes, and improving clamping reliability and processing accuracy.

[0011] In the above technical solution, the material support frame further includes: The upright frame is fixed to the machine frame, and a fourth slide is provided on the upright frame; Mounting plate, uprights are set on both sides of the mounting plate, and process holes are provided on the mounting plate; The movable plate is connected to the fourth sliding platform on both sides and moves by relying on the fourth sliding platform; The second telescopic cylinder is located at the bottom of the mounting plate, and the movable end of the second telescopic cylinder extends from the process hole to the space between the uprights and is fixed to the bottom of the movable plate. The dynamic compensation module is mounted on the movable plate and comes into contact with the material.

[0012] In this technical solution, the material support frame is driven by the second telescopic cylinder to move the movable plate along the fourth slide table to accommodate materials of different specifications. It is equipped with a dynamic compensation module for real-time monitoring to ensure the stability of clamping and cutting and improve processing accuracy.

[0013] In the above technical solution, the first clamping unit further includes: The fixed base is fixed to the frame and has a vertical plate with pre-drilled holes. The motor is mounted on a fixed base, with its output end facing the pre-drilled hole. The clamping component is fixed to the motor output end and is set on the reserved hole.

[0014] In this technical solution, the first clamping unit drives the clamping components to move by a motor. Relying on the stable installation of the fixed base and the upright plate, it realizes precise clamping and rotation of materials, adapts to the processing of irregular pipes, ensures the stability of the cutting process, and improves processing accuracy and adaptability.

[0015] In the above technical solution, the clamping component further includes: A turntable is set on a pre-drilled hole; The pad is placed on the turntable and is used to contact the material. The inside of the pad is hollowed out and has a dynamic compensation module.

[0016] In this technical solution, the clamping component contacts the material through a turntable and pad, and the hollow design embeds a dynamic compensation module, which not only achieves stable clamping of irregularly shaped pipes, but also monitors the status in real time, ensuring clamping reliability and helping to improve processing accuracy.

[0017] In the above technical solution, a fifth slide is further provided at the bottom of the fixed clamp, and the fifth slide shares the slide rail of the third slide.

[0018] In this technical solution, the fifth slide at the bottom of the fixed clamp shares the slide rail of the third slide, which simplifies the equipment structure layout, ensures consistent displacement, facilitates adaptation to materials of different lengths, reduces adjustment difficulty, and improves operational convenience and equipment space utilization.

[0019] In the above technical solution, the dynamic compensation module further includes: The first sensor is mounted on the movable plate. The second sensor is mounted on the pad. The controller is connected to the host computer. The controller monitors and judges the data from the first and second sensors, and controls the first and second telescopic cylinders through the host computer to compensate for the dynamic deviation of the material.

[0020] In this technical solution, the dynamic compensation module collects data in real time through dual sensors, and through the collaboration of the controller and the host, drives the cylinder to correct the dynamic deviation of the material, ensuring the stability of clamping and cutting, and greatly improving the processing accuracy and product consistency.

[0021] Furthermore, the above technical solution also includes: The positioning component includes a laser emitter and a laser receiver, with the laser emitter mounted on the housing and the laser receiver mounted on the mounting base. Both the laser transmitter and the laser receiver are controlled by the host computer.

[0022] In this technical solution, the positioning component is controlled by the host to work with the laser emitter and receiver to form a precise positioning reference, quickly calibrate the material clamping center and cutting path, ensure positioning accuracy, and help improve processing consistency and efficiency.

[0023] Furthermore, in the above technical solution, the bottom of the frame is integrally formed with a material dropping frame, and a movable door is provided on one side of the material dropping frame.

[0024] In this technical solution, the integrated material drop frame at the bottom of the frame can collect processing waste in a centralized manner. Combined with the movable door design, it simplifies the waste cleaning process, keeps the processing environment clean, reduces manual cleaning costs, and improves production auxiliary efficiency.

[0025] In the above technical solution, a gasket is further provided on the movable plate, and multiple channel structures are provided on the gasket, with the first sensor disposed within the channel structures.

[0026] In this technical solution, the pads on the movable plate, together with the channel structure, are used to install the first sensor. This not only securely supports the material and prevents damage, but also allows the sensor to accurately collect data, assisting in dynamic compensation and improving clamping and processing accuracy.

[0027] The beneficial effects of this invention are as follows: 1. The symmetrical layout of the fixed clamp and the clamping components on both sides, combined with the dual-station parallel operation design, significantly shortens the waiting time for loading and unloading, and improves the utilization rate of the equipment. At the same time, the dynamic compensation module and the host machine work together to correct the material position and clamping status in real time. Combined with the precise calibration of the positioning components, the cutting accuracy is improved and the product consistency is significantly enhanced. Furthermore, the height-adjustable design of the material support component and the adaptable structure of the clamping unit are compatible with different specifications of irregular-shaped pipes, expanding the applicability of the equipment.

[0028] 2. Before the material is clamped, the laser beam emitted by the laser emitter is received by the laser receiver to form a positioning reference line, ensuring that the clamping centers at both ends of the material are precisely aligned with the cutting path of the laser cutting equipment, further improving processing consistency.

[0029] 3. The segmented second slide design enables independent collaborative operation of the two workstations, further shortening the processing cycle; the application of high-precision linear guides and servo cylinders improves the adjustment accuracy and adaptability of the equipment; the addition of a buffer device protects the surface quality of materials and reduces equipment noise; the material identification and adaptive processing functions enhance the intelligence level of the equipment, making it particularly suitable for processing scenarios with multiple materials and large quantities, significantly reducing the intensity of manual operation and improving production efficiency and product qualification rate.

Additionally, features described with reference to certain examples may be combined in other examples.

[0036] Example 1: This embodiment discloses a multi-station flat cutting machine including a frame 1, a first slide table 2, a laser cutting device 3, a main unit 4, a fixed clamp 5, a clamping module 6, a material support assembly 7, and a dynamic compensation module 8; The frame 1 serves as the installation foundation for the entire equipment, providing stable support for all functional components. A fifth slide 9 is fixedly mounted on the frame 1. This fifth slide 9 shares a set of slide rails with the third slide 71 and the second slide 61, simplifying the structural layout and ensuring consistent displacement of related components. A fixed clamp 5 is mounted in the middle of the frame 1 via the fifth slide 9. Inside its outer shell 51 is a first clamping unit 52. The fixed base 521 of the first clamping unit 52 is securely connected to the frame 1 by bolts. Pre-drilled holes on the vertical plate of the fixed base 521 provide installation space for the clamping component 523. A motor 522 is fixed to the fixed base 521, and its output end passes through the pre-drilled holes and is rigidly connected to the turntable 5231. A pad 5232 on the turntable 5231 directly contacts the material, and a second sensor 82 is embedded in the hollow area inside the pad 5232 to achieve real-time monitoring of the material clamping status.

[0037] Clamping modules 6 are symmetrically arranged on both sides of the fixed clamping base 5. Each clamping module 6 includes a second slide 61 and two parallel clamping components 62. The second slide 61 is fixedly laid on the frame 1, providing a horizontal displacement track for the clamping components 62. The first slide 621 of the clamping component 62 slides in cooperation with the second slide 61. The second clamping unit 6211 on the first slide 621 has the same structure as the first clamping unit 52, ensuring uniform clamping force on both sides of the material. The second slide 622 is fixed to the end of the second slide 61. The movable end of the first telescopic cylinder 6221 installed above it is fixedly connected to the first slide 621. Through the telescopic movement of the first telescopic cylinder 6221, the first slide 621 can be driven to move closer to or away from the fixed clamping base 5 along the second slide 61. At the same time, the first telescopic cylinder 6221 can apply a continuous and stable thrust to the first slide 621, forcing the second clamping unit 6211 to cooperate with the first clamping unit 52 to firmly clamp the material and prevent displacement during processing.

[0038] The material support assembly 7 is positioned between the fixed clamp 5 and the clamping assembly 62. The third slide 71 is fixed to the frame 1. The upright 721 of the material support frame 72 is fixedly connected to the frame 1. A fourth slide 7211 is symmetrically mounted on both sides of the upright 721. A mounting plate is fixed to the top of the upright 721, and the movable end of the second telescopic cylinder 75 at its bottom passes through a process hole and is fixed to the bottom of the movable plate 74. The movable plate 74 slides along the fourth slide 7211 on both sides and can move up and down along the fourth slide 7211 under the drive of the second telescopic cylinder 75. The pad 11 on the movable plate 74 directly supports the material. The channel structure on the pad 11 provides an installation position for the first sensor 81, and the channel design does not affect the stability of the pad 11 in supporting the material. The material support assembly 7 can be adjusted vertically to accommodate materials of different diameters, ensuring that the center of the material is aligned with the center of the clamping unit, laying the foundation for precise clamping.

[0039] The dynamic compensation module 8 consists of a first sensor 81, a second sensor 82, and a controller 83. The first sensor 81 is embedded in the hole of the pad 11 and contacts the bottom of the material. The second sensor 82 is installed inside the pad 5232. Both are electrically connected to the controller 83, which in turn communicates with the host machine 4 on one side of the frame 1. When the material is clamped and placed on the material support assembly 7, the first sensor 81 monitors the material's support height deviation in real time, and the second sensor 82 senses the contact pressure and displacement changes between the material and the pad 5232. The controller 83 collects data from both types of sensors and analyzes it. If it detects a positional shift or abnormal clamping force, it immediately transmits a signal to the host machine 4. The host machine 4 responds quickly and controls the first telescopic cylinder 6221 to adjust the thrust and the second telescopic cylinder 75 to adjust the height of the movable plate 74, thereby achieving dynamic position compensation for the material and ensuring processing accuracy.

[0040] The bottom of the frame 1 has an integrally formed material drop frame that surrounds the processing area. Waste generated during processing falls directly into the material drop frame. When the waste accumulates to a certain amount, it can be cleaned by opening the movable door on one side of the material drop frame, which is convenient for operation and keeps the processing environment clean.

[0041] The laser cutting equipment 3 is installed on the first slide table 2, which is fixed above the frame 1. The laser cutting equipment 3 is connected to the host 4 via a cable. The host 4 controls the laser cutting equipment 3 to move horizontally along the first slide table 2 according to the preset processing parameters. At the same time, it coordinates the motor 522 of the fixed clamp 5 and the clamping assembly 62 to drive the turntable 5231 to rotate, thereby rotating the material and achieving precise cutting of the flat or inclined surface of the material end.

[0042] The workflow of this embodiment is as follows: First, the processing parameters are set by the host 4. After the equipment is started, the second telescopic cylinder 75 drives the movable plate 74 to rise to the preset height. The worker places the material on the pad 11, and the material support component 7 supports the material. Then, the first telescopic cylinder 6221 drives the first slide 621 to approach the fixed clamp 5. The second clamping unit 6211 cooperates with the first clamping unit 52 to clamp the material. At this time, the second sensor 82 monitors the clamping force, and the first sensor 81 monitors the support status. The host 4 controls the dynamic compensation module 8 to work continuously and correct the material position deviation in real time. The laser cutting equipment 3 moves along the first slide 2, and at the same time, the motor 522 drives the material to rotate to complete the cutting operation. The waste generated during the cutting process falls into the discharge frame. When one station is processing, the other station can simultaneously perform loading and unloading operations to achieve continuous production.

[0043] Example 2: Based on Embodiment 1, this embodiment optimizes the cooperation logic between the clamping component 62 and the material support component 7, further improving processing efficiency and stability. The specific improvements are as follows: The positioning component 10 is mounted on the fixed clamp 5 and the clamping component 62. The laser emitter 101 and the laser receiver 102 work together to complete the material positioning calibration. The laser emitter 101 of the positioning component 10 is fixed to the outer shell 51 of the fixed clamp 5, and the laser receiver 102 is correspondingly installed on the fixed base 521 of the first clamping unit 52. Both are controlled by the host 4 to start and stop. Before the material is clamped, the laser beam emitted by the laser emitter 101 is received by the laser receiver 102 to form a positioning reference line, ensuring that the clamping centers at both ends of the material are accurately aligned with the cutting path of the laser cutting equipment 3, further improving the consistency of processing.

[0044] Example 3 This embodiment is designed for batch processing scenarios, optimizing the continuous operation capability and component collaboration efficiency of the equipment. The specific structure is as follows: The second slide 61 on the frame 1 adopts a segmented design. The second slides 61 on both sides of the fixed clamp 5 are independently controlled and can drive the clamping components 62 on both sides to perform clamping actions, realizing independent or collaborative processing of the two workstations. For example, when one workstation is performing cutting operations, the other workstation can complete loading, clamping and positioning. After the cutting on one side is completed, the host 4 controls the laser cutting equipment 3 to quickly switch to the other workstation for processing, achieving seamless connection and greatly improving production efficiency.

[0045] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
