Description

Technical Field

[0001] The invention relates to the field of laser cutting, in particular to a non-contact type curved surface metal cutting device. Background Art

[0002] In modern manufacturing, non-contact processing technology is gradually becoming an important branch in the field of metal processing with its unique advantages, especially in arc metal cutting. Non-contact technology uses high-energy beams such as laser and plasma for cutting, avoiding many limitations brought by traditional mechanical contact processing. The core of this technology is that it can achieve high-precision and high-efficiency cutting operations without direct contact with the workpiece. With the rapid development of aerospace, automobile manufacturing, precision instruments and other industries, the cutting accuracy and processing efficiency requirements for metal workpieces, especially arc workpieces, are increasing. Non-contact arc metal cutting technology has become an ideal choice to meet these high-precision and high-efficiency processing needs because of its significant advantages such as reducing workpiece deformation, avoiding tool wear, and improving processing flexibility. Therefore, the research and development and promotion of non-contact arc metal cutting equipment is of great significance to improving the overall processing level of the manufacturing industry and promoting industrial upgrading.

[0003] Although traditional arc surface metal cutting technology has played an important role in the past few decades, its inherent limitations have gradually emerged. Traditional technology mainly relies on mechanical tools for cutting, which not only has extremely high requirements on the material and precision of the tools, but also easily generates a large amount of heat and metal debris during the cutting process, causing large thermal impact on the workpiece and rough cutting surface. Problems, especially for arc surface workpieces with complex shapes and various sizes, traditional technology often requires frequent replacement of tools or complex tooling adjustments, which not only increases production costs, but also seriously affects processing efficiency. In addition, traditional cutting methods also have safety hazards, such as tool splashing, improper operation, etc., which may cause personal injury. These limitations not only restrict the further development of the metal processing industry, but also make it difficult to meet the modern industry's high-precision, high-efficiency, safe and environmentally friendly processing requirements. Therefore, exploring and developing new non-contact arc surface metal cutting technology has become the key to breaking through the bottleneck of traditional technology and promoting industry progress.

[0014] Compared with the prior art, the invention provides a non-contact curved metal cutting device, which has the following beneficial effects: This equipment has made significant progress in enhancing operational safety and environmental protection, and has a qualitative improvement compared to traditional technologies. Traditional cutting equipment usually produces strong light, sparks and a large amount of metal debris flying when working, posing a serious threat to the operator's eyes, skin and body, and also polluting the working environment.

The placement plate of the placement component of this equipment adopts an arc-shaped structure design, which matches the shape of the metal workpiece to be cut and can better adapt to the placement requirements of the arc workpiece. The support can move horizontally along the groove on the top of the processing table accurately, so that the height of the placement plate can be flexibly adjusted according to the thickness and shape of the workpiece.

At the same time, the anti-sliding blocks 803 equidistantly arranged on the top of the placement plate and the trapezoidal structure of the anti-sliding block as a whole further enhance the stability and safety of the workpiece during the placement process and avoid cutting errors caused by sliding or offset.

[0029] Working principle: When the equipment is started, first connect the external power supply to provide power to the drive motor 101. The drive motor 101 serves as the power source of the entire equipment. Its output end is closely connected to the input end of the gear set 701 through a precision bearing. This design ensures the efficient and stable transmission of the motor's rotational power, thereby starting the entire transmission system. The gear set 701 is the core component of the transmission system. It consists of four sets of gears carefully arranged into a trapezoidal installation structure. This design not only optimizes the power transmission path, but also improves the transmission efficiency. The top two sets of gears serve as driving wheels, which are fixed together with the pulley 702 through a high-strength connection. When the drive motor 101 drives the gear set 701 to rotate, the two sets of driving wheels transmit power to the threaded part through the pulley 702. The introduction of the adjusting rod 703 and the pulley 702 not only realizes the long-distance transmission of power, but also effectively absorbs the vibration and impact in the transmission process through its elastic characteristics, thereby improving the stability of the system. The two sets of gears at the bottom serve as driven wheels, which are tightly meshed with the top driving wheels. This meshing connection method not only ensures the continuity of power transmission, but also realizes the precise adjustment of the rotation speed through the design of the gear ratio. This feature is very important for the subsequent height adjustment of the placement component 8 and the fine control of the cutting process. After receiving the power, the threaded adjusting rod 703 starts to rotate, and its outer thread is tightly matched with the threaded hole inside the support member 801 of the placement component 8, forming a stable spiral transmission pair. With the rotation of the threaded adjusting rod 703, the support member 8 01 can move up and down precisely along the groove on the top of the processing table 1. This design allows the height of the placement plate 802 to be flexibly adjusted according to the thickness and shape of the metal workpiece to be cut, ensuring stability and accuracy during the cutting process. The placement plate 802 of the placement component 8 adopts an arc-shaped structure design to match the shape of the metal workpiece to be cut. This design not only improves the placement stability of the workpiece, but also reduces the error during the cutting process. Anti-slip blocks 803 are equidistantly arranged on the top of the placement plate 802. These anti-slip blocks are made of wear-resistant and heat-resistant materials, which can effectively prevent the workpiece from sliding due to vibration or external force during the cutting process. At the same time, the suction cup 805 on the top of the side connecting plate 804 can generate a strong adsorption force to firmly fix the workpiece on the placement plate 802, further increasing the stability of the cutting process. During the cutting process, the main electric guide rail 4 and the auxiliary electric guide rail 401 play a vital role. The main electric guide rail 4 is installed horizontally on the side of the side plate 2, and a high-precision motor and transmission mechanism are integrated inside. When receiving a control command, the main electric guide rail 4 can drive the auxiliary electric guide rail 401 to move horizontally in the front and back directions, and the auxiliary electric guide rail 401 can realize the horizontal movement of the installation structure in the left and right directions through its internal motor and transmission mechanism. In this way, through the linkage of the main and auxiliary electric guide rails, the laser cutter 6 can accurately move in three-dimensional space and cut metal workpieces in any shape. The laser cutter 6 is the core component of the cutting process. It is installed on the adjustment slide table 5.The adjusting slide table 5 is connected to the auxiliary electric guide rail 401 through the slide rail, which can realize fine adjustment in the left and right directions. This design enables the laser cutter 6 to maintain a high degree of flexibility and precision during the cutting process. Positioning holes and limit plates are equidistantly arranged on both sides of the adjusting slide table 5. These positioning holes and limit plates not only provide stable support for the laser cutter 6, but also ensure its stability and accuracy during movement. When the laser cutter 6 receives a cutting instruction, it will emit a high-energy laser beam according to the preset cutting path and parameters. This laser beam has extremely high energy density and focusing, and can melt, vaporize or reach the ignition point of the metal workpiece in an instant, thereby realizing non-contact cutting. This cutting method not only avoids the traditional cutting method The direct contact between the tool and the workpiece reduces the problems of tool wear and workpiece deformation, and also improves cutting efficiency and accuracy. During the entire cutting process, the shading plate 301 and the protective plate 3 play an important protective role. The shading plate 301 is made of shading material and can effectively block the strong light generated during the cutting process. It is embedded in the protective plate 3 and fixedly connected to the protective plate 3 through a hinge. This design not only facilitates the switching and adjustment of the shading plate 301, but also ensures that the operator's eyes are protected from strong light. The protective plate 3 is made of a solid material, which can prevent the metal debris generated during the cutting process from splashing outside the operating area. It can not only protect the personal safety of the operator, but also keep the working environment clean and hygienic.
