High-precision fiber laser metal cutting devices have emerged. It uses fiber laser technology to focus high-energy density laser beams to accurately cut metal materials. It not only has fast cutting speed and small heat-affected zone, but also can achieve precise processing of complex shapes and tiny details. This cutting method not only meets the modern manufacturing industry's pursuit of high quality and high efficiency, but also greatly promotes the development of intelligent manufacturing and automated production. Therefore, high-precision fiber laser metal cutting devices have become an indispensable and important equipment in modern manufacturing, which is of great significance to improving production efficiency, ensuring product quality and promoting industrial upgrading.

[0003] However, traditional metal cutting technologies, such as mechanical cutting and oxyacetylene cutting, have many shortcomings. First, the accuracy of these traditional cutting methods is limited, and it is difficult to meet the needs of modern manufacturing for high-precision processing, especially when processing complex shapes and tiny details, large errors and defects often occur. Secondly, the waste chips generated during the cutting process are often difficult to collect effectively, and are easy to accumulate and scatter, which not only increases the difficulty of cleaning, but also may cause pollution to the cutting equipment and the working environment.

[0014] Compared with the prior art, the invention provides a high-precision fiber laser metal cutting device, which has the following beneficial effects: The device realizes efficient collection and discharge of waste chips through carefully designed collection components and protection components. Compared with traditional laser metal cutting machines, the waste chips generated during the cutting process are often difficult to collect effectively and are easy to accumulate and scatter, which not only increases the difficulty of cleaning, but also may cause pollution to the cutting equipment and working environment. The inclined baffle and inclined placement groove design in the collection component make the waste chips generated during the cutting process naturally fall into the collection box under the action of gravity, avoiding the accumulation and scattering of waste chips, reducing the difficulty and time of cleaning. At the same time, the funnel seat, water curtain plate and guide plate in the protection component cooperate with each other to form a complete smoke, exhaust gas and spark treatment system.

[0029] Working principle: When the equipment is started, first, the operator gently pushes open the protective door 101, which is connected to the cutting machine case 1 through a movable hinge, which is easy to open quickly and close tightly, greatly improving the convenience of operation. A special protective window 102 is embedded in the protective door 101. It is made of multi-layer laminated high-temperature resistant tempered glass. This material not only has excellent impact resistance, but can also effectively resist sparks and splashes that may be generated during the cutting process, thereby effectively protecting the safety of the operator; moreover, its good optical transparency also allows the operator to clearly observe the cutting process to ensure the accuracy of the operation. More importantly, a sealing strip is set at the connection between the protective window 102 and the protective door 101. This detailed design effectively ensures the cutting The sealing of the cutting machine box 1 prevents the intrusion of external dust, impurities and other pollutants, which threaten the cutting accuracy and equipment life. After the metal material to be cut is accurately placed in the designated position, the operator slowly closes the protective door 101, and the cutting assembly 7 immediately enters the standby state. The cutting assembly 7 is the core component of the entire equipment. Its workpiece frame 701 not only provides a stable support for the laser generator 702 and the laser cutting head 703, but also ensures the stability of the entire cutting process. The laser generator 702, as an energy source, can instantly stimulate a high-energy laser beam, and the laser cutting head 703 is responsible for accurately focusing and projecting this energy onto the metal material to achieve fast and accurate cutting. The laser cutting head 703 is perpendicular to the funnel seat 401. The position of the top ensures the stability during the cutting process, and also greatly improves the accuracy and precision of the cutting, making the cutting surface flat and smooth, reaching high-quality processing standards. During the cutting process, the main rail 5 and the auxiliary rail 6 play a vital role. The main rail 5 is laid horizontally and extends along a specific direction, providing a stable and smooth horizontal motion track for the cutting component 7, while the auxiliary rail 6 is arranged perpendicular to the main rail 5, and one end of the auxiliary rail 6 is tightly connected to the side of the main rail 5. The two together constitute a flexible two-dimensional motion system. This design enables the cutting component 7 to move freely in the cutting machine case 1, whether it is straight line cutting or complex shape processing, it can be easily handled, realizing all-round and high-precision cutting of metal materials. At the same time, The protection component 4 is also silently guarding the safety and cleanliness of the entire cutting process. The funnel seat 401 on the top of the partition 2 is cleverly designed, and the funnel-shaped space inside it can effectively collect smoke and exhaust gas generated during the cutting process to prevent them from spreading everywhere and polluting the working environment. The water curtain plate 402 serves as a preliminary filtering layer to cool and purify smoke, exhaust gas and sparks, further reducing the emission of harmful substances, while the pad 403 plays a supporting and protective role to ensure the stable operation of the funnel seat 401. The guide plate 404 is installed at an angle as a whole, and a grid design is adopted on the inside. This structure can not only effectively guide smoke, exhaust gas and sparks to be discharged in a specified direction to prevent them from being retained and diffused in the cutting machine case 1, but also increase the exhaust area.The smoke exhaust efficiency is improved, making the working environment fresher. The waste generated during the cutting process also naturally falls into the collection component 3 under the action of gravity. The inclined baffles 302 on both sides of the collection box 301 are installed at a specific tilt angle and are in a staggered state. This design can more effectively guide the cutting waste to fall into the collection box, avoiding the accumulation and scattering of waste. The inclined design of the inclined placement groove 303 further ensures the smooth sliding and collection of waste, greatly reducing the difficulty and time of cleaning and improving work efficiency. In addition, the automatic cleaning function of the cleaning component 8 is also a highlight of the device. The water tank 801 stores clean water, and the water is transported to the transmission pipe 804 through the precise cooperation of the flange pipe group 802 and the micro water pump 803, and then transported to the funnel seat 401 through the transmission pipe to wet the smoke and exhaust gas. This design not only effectively reduces the emission of smoke and exhaust gas, but also improves the quality of the working environment, allowing operators to work in a healthier and more comfortable environment. The bottom of the micro-pump 803 is fixedly connected to the top of the partition 2. This design ensures the stability of its work and ensures the smooth progress of the cleaning process. Finally, the overall design of the partition 2 is connected by riveting. The structure is firm and stable, and can effectively support and separate the internal space of the cutting machine case 1. The partition 2 divides the interior and bottom of the cutting machine case 1 into four independent spaces, which are used for different functional areas such as cutting, collection, and protection, respectively, to achieve the rational use and efficient management of space. This partition design not only improves the cutting efficiency, but also reduces the noise and vibration generated during the cutting process, providing operators with a more quiet and comfortable working environment. ,
