Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment, and in particular to a laser cutting machine blade module and a laser cutting machine. Background Technology

[0002] The blades are the core support components of the laser cutting machine's blanking line. They primarily provide a stable and flat support platform for sheet metal cutting, ensuring the sheet remains level, without warping or wobbling during the laser cutting process, thus guaranteeing stable cutting path and dimensional accuracy. The blades are arranged at intervals, avoiding the laser-burned area while evenly supporting the sheet metal to prevent it from sagging under its own weight. They also provide space for cutting fumes and debris to fall, preventing debris accumulation from affecting cutting quality. Therefore, they are a crucial foundational component for ensuring laser cutting accuracy and sectional finish.

[0003] Currently, most blades are integral U-shaped bent blades made of carbon steel. These blades are made by bending carbon steel plates into a U-shaped cross-section and are fixedly installed on the equipment frame. They have a simple structure, are easy to manufacture, rely on the bending structure to increase rigidity, and rely on the carbon steel material to provide basic support strength. They are an integral, non-separable structure and are widely used in various laser cutting equipment.

[0004] However, during use, the cutting blade is prone to thermal deformation due to the high temperature of the laser, causing the middle area of ​​the blade to bulge upwards or downwards, damaging the supporting plane. Secondly, long-term operation can lead to slag-scraping deformation, with the accumulation of waste residue causing the blade to deform from a localized area to an overall deformation. There is often a lack of early monitoring methods for blade deformation, and by the time it affects machining accuracy, it has already resulted in waste and production losses, leading to reactive maintenance and impacting processing quality. Utility Model Content

[0005] This invention addresses the problem of difficulty in monitoring early deformation during the use of laser cutting blades by providing a laser cutting machine blade module.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a laser cutting machine blade module, including a blade body, wherein two blade bodies are provided, the two blade bodies are parallel to each other, and a middle support and two side supports are provided between the two blade bodies, both of which are connected to the two blade bodies; along the length direction of the blade body, the middle support is located in the middle of the blade body, and the two side supports are respectively located at both ends of the blade body; a first observation port is provided on the upper edge of the side supports, and a second observation port is provided on the upper edge of the middle support, the width of the second observation port is smaller than the width of the first observation port, and in the projection along the length direction of the blade body, the second observation port is located in the middle of the first observation port. Based on the structure of this blade module, operators can observe the first and second observation ports along the length of the blade body. By observing the relative position of the second and first observation ports, they can intuitively see whether the blade is bending upwards or downwards, enabling early identification of deformation and avoiding processing waste and production losses due to undetected deformation. On the other hand, this solution improves the deformation resistance of the blade body by setting an intermediate support in the middle, further extending its service life.

[0007] As a preferred embodiment of a laser cutting machine blade module, the side bracket and the intermediate bracket are equipped with pins. Both ends of the pins protrude from the two end faces of the respective side bracket or intermediate bracket. The blade body has connecting holes at both ends and the middle position. After passing through the corresponding connecting holes, a cotter pin is inserted to secure the blade body. This quick-release structure of pins and cotter pins allows for rapid and individual disassembly and replacement of the blade body, reducing maintenance costs and shortening downtime for replacement.

[0008] As a preferred embodiment of a laser cutting machine blade module, a bent section is provided in the middle of the blade body along its height. This bent section protrudes in a zigzag pattern towards the side support and the middle support, extending along the length of the blade body. This central bending structure enhances the vertical rigidity of the blade body, mitigating thermal deformation caused by high laser temperatures and deformation due to slag accumulation, thus extending the effective service life of the blade.

[0009] As a preferred embodiment of a laser cutting machine blade module, two pins are provided on both the side bracket and the middle bracket, located above and below the bent portion, respectively. The double pins fix the blade body, resulting in more even force distribution and more stable constraint, further improving support accuracy and resistance to deformation.

[0010] As a preferred embodiment of a laser cutting machine blade module, both the side support and the intermediate support are channel steel, with the channel steel grooves extending vertically, and the pins penetrating both sides of the channel steel. Channel steel structures offer high strength, good rigidity, and are readily available; the vertical grooves facilitate pin penetration and installation, resulting in strong structural stability.

[0011] As a preferred embodiment of a laser cutting machine blade module, the slots of the two side supports are arranged opposite each other, and a connecting plate is provided on the bottom surface of the slot bottom plate of the side supports. The connecting plate is used to connect external equipment. The bottom connecting plate increases the contact area with the equipment, making the installation more stable and ensuring the overall installation strength and positioning accuracy of the module.

[0012] As a preferred implementation of a laser cutting machine blade module, multiple intermediate supports are provided, evenly distributed between the two side supports. These multiple sets of intermediate supports can provide multi-point support for the long blade body, further improving its resistance to deformation, enhancing the overall support flatness, and making it suitable for use with large-table laser cutting machines.

[0013] As a preferred implementation of a laser cutting machine blade module, the first observation port and the second observation port have the same depth. Having the same observation port depth ensures that even minute bending deformations can be observed, improving the accuracy of deformation assessment.

[0014] On the other hand, this utility model also provides a laser cutting machine, including a processing table, on which multiple sets of the aforementioned laser cutting blade modules are provided. By using the aforementioned blade modules, the laser cutting machine can observe the early deformation of the blades, thereby improving the processing accuracy of the cutting machine, reducing scratches on the sheet metal, and increasing the yield rate.

[0015] As a preferred solution for laser cutting machines, the spacing between adjacent laser cutting blade modules is the same as the width of the side support. This ensures equal spacing between all blades on the table surface, resulting in uniform table support, consistent gaps, and facilitates waste material falling and airflow. Simultaneously, it guarantees stable support for the sheet material, improving cutting accuracy and cross-sectional quality.

[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: By combining the first and second observation ports of different widths on the side support and the middle support, the bending deformation of the blade body can be directly observed, enabling early identification of deformation and avoiding waste and production losses due to delayed detection. Simultaneously, the middle support enhances the deformation resistance of the blade's central section, extending its service life. The blade body is fixed using a quick-release structure with pins and cotter pins, allowing for rapid disassembly and replacement, reducing maintenance costs and downtime. The bent portion in the middle of the blade body improves vertical stiffness, mitigating thermal deformation and slag accumulation deformation. Combined with the upper and lower double pin fixing method, this ensures uniform force distribution and stable constraint on the blade. This design further enhances support precision and resistance to deformation. The side and intermediate supports are made of channel steel, offering high strength, rigidity, and ease of installation. The connecting plate at the bottom of the side supports increases the contact area, improving installation stability and positioning accuracy. Multiple evenly distributed intermediate supports provide multi-point support for long blades, improving overall flatness and adapting to large-table equipment. Observation ports of equal depth enhance the accuracy of observing minute deformations. Laser cutting machines equipped with this blade module can monitor blade deformation in advance, improving processing precision, reducing scratches on the sheet metal, and increasing product yield. The evenly spaced blade modules ensure uniform table support and consistent gaps, facilitating waste disposal and airflow, further guaranteeing cutting precision and cross-sectional quality.

Obviously, the embodiments described below are only some embodiments of this patent, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0027] Example 1

[0028] like Figure 1 , Figure 2 As shown, a laser cutting machine blade module includes two parallel blade bodies 4. A middle support 5 and two side supports 1 are disposed between the two blade bodies 4. The middle support 5 and the side supports 1 are fixedly connected to the two blade bodies 4. Along the length direction of the blade bodies 4, the middle support 5 is located in the middle of the blade body 4, and the two side supports 1 are respectively located at both ends of the blade bodies 4. A first observation port 6 is opened on the upper edge of the side supports 1, and a second observation port 7 is opened on the upper edge of the middle support 5. The width of the second observation port 7 is smaller than the width of the first observation port 6, and in the projection along the length direction of the blade body 4, the second observation port 7 is located in the middle of the first observation port 6. The depth of the first observation port 6 and the second observation port 7 is the same. Both the side bracket 1 and the intermediate bracket 5 are equipped with pins 2. The two ends of the pins 2 pass through the two end faces of the corresponding side bracket 1 or the intermediate bracket 5. The blade body 4 is provided with connecting holes at both ends and the middle position. After the pins 2 pass through the corresponding connecting holes, cotter pins 3 are inserted at the ends to achieve axial positioning, so as to reliably fix the blade body 4 to the side bracket 1 and the intermediate bracket 5.

[0029] The blade body 4 has a bent portion 401 in the middle of its height direction. The bent portion 401 protrudes in a mountain-shaped manner towards the side opposite to the side support 1 and the intermediate support 5 (e.g., Figure 6As shown, the upper and lower edges of the bent portion 401 are abutted against the sides of the side support 1 and the intermediate support 5, and the middle part protrudes outward from the side support 1 and the intermediate support 5, and extends continuously along the length direction of the blade body 4; two pins 2 are provided on both the side support 1 and the intermediate support 5, and the two pins 2 are located above and below the bent portion 401 respectively, forming a two-point constraint. Both the side support 1 and the intermediate support 5 are made of channel steel, and the groove of the channel steel is arranged in the vertical direction. The pins 2 penetrate vertically through the two side walls of the channel steel. The grooves of the two side supports 1 are arranged opposite each other. A connecting plate 8 is fixedly provided on the bottom surface of the groove bottom plate of the side support 1. The connecting plate 8 is used to fixally connect with the worktable of the laser cutting machine.

[0030] Multiple intermediate supports 5 are provided, and the multiple intermediate supports 5 are evenly arranged between the two side supports 1 along the length direction of the blade body 4, forming multi-point support for the blade body 4 and improving the overall support rigidity and flatness.

[0031] After the blade module is put into use, the deformation of the blade can be observed periodically. The specific operation is as follows: the operator looks along the length of the blade body and aligns the first observation ports 6 on the two end supports 1. If the blade does not bend at this time, the observed state should be as follows. Figure 3 As shown, the second observation port 7 is located in the middle of the first observation port 6, and the bottom edge of the second observation port 7 is flush with the bottom edge of the first observation port 6. The top edge of the middle support 5 is flush with the top edge of the side support 1. If the blade protrudes upwards, the observed state is as follows. Figure 4 As shown, the bottom edge of the second observation port 7 is higher than the bottom edge of the first observation port 6 (and can be seen); if the blade is concave, the observed state is as follows. Figure 5 As shown, the upper edge of the intermediate support 5 is located in the first observation port.

[0032] Furthermore, graduations can be set in the first and second observation ports to more accurately reflect the amount of deformation.

[0033] Example 2

[0034] This embodiment further provides a laser cutting machine, including a processing table, on which multiple sets of laser cutting machine blade modules as described in Embodiment 1 are provided, wherein the spacing between adjacent laser cutting machine blade modules is the same as the width of the side support 1.

[0035] As can be seen from the above embodiments, the advantages of this utility model are:

[0036] This utility model's laser cutting machine blade module, through the staggered layout of wide and narrow observation ports, allows for direct monitoring of early deformation of the blade body, avoiding material waste and reduced processing accuracy due to undetected deformation. The intermediate support and double pin fixing structure enhance the overall rigidity and support stability of the blade, while the central bending section effectively mitigates high-temperature laser deformation and slag accumulation deformation, extending the blade's service life. The quick-release structure of the pins and cotter pins facilitates individual blade replacement, reducing maintenance costs and downtime. The channel steel support boasts high strength and convenient installation, while the bottom connecting plate enhances the module's installation stability and positioning accuracy. Multiple evenly arranged intermediate supports enhance the deformation resistance of long blades, ensuring support flatness. Observation ports of equal depth improve the accuracy of deformation judgment. The overall structure is compatible with large-table laser cutting machines, providing stable support for the material, facilitating slag fall, and ensuring cutting accuracy and cross-sectional quality.
