[0002] In the field of metal processing and manufacturing, cutting is an extremely critical process. Traditional metal cutting methods, such as mechanical cutting (such as sawing, shearing) and flame cutting, have many limitations. When facing some metal parts with complex shapes or high precision requirements, mechanical cutting has low cutting efficiency and is prone to produce large mechanical stress, which has an adverse effect on the quality of metal parts. Although flame cutting can process thicker metal materials, a large amount of heat is generated during the cutting process, resulting in large thermal deformation of metal parts, and harmful gases and smoke are emitted, causing environmental pollution.

[0003] With the continuous development of laser technology, laser cutting has been increasingly widely used in the manufacture of metal parts due to its significant advantages such as high precision, high speed, good cutting quality and non-contact processing.

For example, the moving structure of some devices is not flexible enough, which makes it difficult to quickly and accurately position when cutting complex-shaped metal parts; or when adjusting the height of the cutting head, the accuracy is not high enough, which affects the cutting quality and efficiency.

[0015] Compared with the prior art, the present invention provides a noise reduction cutting device for metal parts manufacturing, which has the following beneficial effects: 1. The noise reduction cutting device for metal parts manufacturing can realize the precise positioning of the laser cutting head in the horizontal direction through the sliding cooperation between the bottom track and the concave frame, and the lateral moving structure on the top of the concave frame (composed of a motor assembly, a motor slide and a moving slide, etc.). The second motor drives the first gear to mesh with the teeth, which can accurately control the lateral moving distance of the motor slide, so that the laser cutting head can perform high-precision cutting on the metal parts according to the preset cutting path. It can also ensure good contour accuracy for the processing of metal parts with complex shapes, effectively reduce processing errors, and improve product quality.

[0016] 2. The noise reduction cutting device for metal parts manufacturing, the up and down displacement structure (including drive components, lead screw, rectangular connecting slider, etc.) can accurately adjust the distance between the laser cutting head and the metal parts. Motor three drives gear three to mesh with gear two to rotate the lead screw, thereby driving the rectangular connecting slider to move up and down. The adjustment accuracy is high, and the appropriate cutting head height can ensure the best focusing effect of the laser beam on the surface of the metal part, so that the energy is evenly distributed during the cutting process, thereby obtaining a smooth and flat cutting section, reducing defects such as burrs and slag, and improving the surface quality of the metal parts after cutting.

[0017] The noise reduction cutting device for metal parts manufacturing has a concave frame that can slide easily on the bottom track with the help of a motor and a moving roller. The operator can quickly move the laser cutting head to the starting position of the metal part to be cut, and can also quickly adjust the overall position of the cutting device when processing different metal parts, adapting to diverse production layouts and processing requirements, thereby improving production preparation efficiency.

[0018] The noise reduction cutting device for metal parts manufacturing has an ingeniously designed disassembly component of the laser cutting head. When the collimating lens and protective lens need to be replaced, the L-shaped hinge block is pulled to release the lock between the card protrusion and the card slot, and then the cover plate and the optical element connected to it are pulled out. The operation is simple and convenient, which greatly shortens the replacement time of optical elements, reduces the difficulty of equipment maintenance, reduces the downtime caused by maintenance, and improves the overall operation efficiency and utilization rate of the equipment.

[0019] The noise reduction cutting device for metal parts manufacturing has a reasonable layout and component selection in structural design. For example, the concave frame is moved by rolling the moving roller in the side roller groove. Compared with some traditional friction moving structures, the friction noise during the movement is effectively reduced. At the same time, during the laser cutting process, the closed design of the cutting area and the reasonable guidance of the airflow (such as the nozzle spraying combustion-supporting gas to take away the molten material while also blocking the noise propagation to a certain extent) can significantly reduce the noise intensity generated by the cutting operation, create a relatively quiet and comfortable working environment for the operator, and reduce the damage of noise to the operator's hearing and physical and mental health.

[0020] The noise reduction cutting device for metal parts manufacturing uses laser cutting technology, which avoids the emission of a large amount of harmful gases and smoke compared to traditional flame cutting. During the cutting process, only a small amount of combustion-supporting gas (such as nitrogen, oxygen or air, etc.) is required, and these gases mainly exist in gaseous form after cutting. It will not produce a large amount of solid waste and harmful smoke, and the pollution to the surrounding environment is extremely small. It meets the environmental protection requirements of modern green manufacturing and is conducive to the sustainable development of the enterprise.

[0021] 7. The noise reduction cutting device used in the manufacture of metal parts has a flexible structure and precise control capabilities, which enable it to adapt to the cutting and processing of metal parts of different shapes, sizes and materials. Whether it is a thin plate or a metal block of a certain thickness, whether it is a simple geometric shape or a complex special-shaped structure, it can be effectively cut by adjusting the cutting parameters and the position of the device. There is no need to frequently replace the cutting equipment, which improves the versatility of the equipment and the flexibility of production, and further improves the production efficiency and economic benefits of the enterprise.

[0022] 8. The noise reduction cutting device used in the manufacture of metal parts has precise cutting position and height control, as well as good cutting quality assurance, so that the cutting process can be carried out smoothly and efficiently, reducing rework and repair operations caused by insufficient cutting accuracy, and greatly shortening the processing time of a single metal part; at the same time, convenient equipment operation and maintenance also reduce downtime in the production process, thereby improving overall production efficiency, enabling enterprises to produce more metal parts that meet quality requirements per unit time, and enhancing the market competitiveness of enterprises.

[0079] Working principle: When it is necessary to cut a metal part, place it under the concave frame 2, fix the metal part with a tooling, start the laser cutting head 3, and then slide the concave frame 2 to the position where cutting is required. Then the lateral moving structure drives the laser cutting head 3 to move lateral to perform displacement cutting. When it is necessary to adjust the distance between the laser cutting head 3 and the metal part, the upper and lower displacement structures extend downward to adjust the gap between the laser cutting head 3 and the metal part.
