Description

Technical Field

[0001] The invention relates to the technical field of dust-free cutting, in particular to a dust-free cutting device and method for processing metal parts of textile machinery. Background Art

[0002] The textile machinery manufacturing industry is divided into two categories: one is the manufacture of complete machines, and the other is the manufacture of special parts and components (such as spindles, cradles, steel collars, wire rings, knitting needles, card clothing, healds, warp droppers, etc.). The special equipment of textile machinery factories that manufacture complete machines accounts for a small proportion of the total equipment of the factory, so under certain conditions, the variety can be changed to produce other machinery. The proportion of factory-specific equipment and special assembly lines that manufacture special parts and components is relatively large (especially knitting needles and card clothing), and it is difficult to change varieties. Among various types of processing work, the proportion of foundry workers is gradually decreasing, and the proportion of cold stamping, grinding, electroplating, polishing, etc. is gradually increasing. CNC machine tools and multi-station automatic machine tools have partially replaced special machine tools, making the adaptability and flexibility of production enhanced.

[0003] Textile machinery has strong technological requirements, complex structures, and many parts. Before leaving the factory, it needs to be pre-assembled or partially assembled, and then undergo production tests or local production tests to ensure that the machine quality meets the requirements. Textile machinery factories all have well-equipped testing departments.

[0004] There are many kinds of parts for textile machinery. For example, there are 1,200 to 1,500 parts for double-cylinder circular hosiery machines, and the processing procedures for parts are diverse. If a factory produces multiple machines at the same time, it is necessary to properly arrange the production rhythm and connection of parts to ensure that the variety and quantity of parts required for the assembly of the entire machine can be provided on schedule on the assembly line. Modern textile machinery industry mostly uses new management means and methods such as computers and system engineering to manage enterprises.

[0005] The main reasons for dust-free treatment during the cutting process of textile machinery parts include the following aspects: Protect the environment and workers' health: The dust generated during the cutting process will cause harm to the environment and workers' health. Dust will not only pollute the air, but may also be inhaled by workers. Long-term inhalation of dust may lead to health problems such as pneumoconiosis. Dust-free cutting can effectively reduce the generation of dust and protect the environment and workers' health. Improve work efficiency: Dust will adhere to cutting tools and workpieces, affecting cutting accuracy and efficiency. Dust-free cutting can reduce the interference of dust and keep cutting tools clean, thereby improving work efficiency. Improve the working environment: Dust is suspended in the air, which will affect the line of sight and increase the difficulty of work. Dust-free cutting can provide a clearer working environment and reduce operational errors caused by obstructed vision. Meet environmental protection requirements: Many countries and regions have strict regulations on industrial emissions. Dust-free cutting can reduce dust emissions, meet environmental protection requirements, and avoid penalties for emission problems. Extend equipment life: Dust attached to the equipment will accelerate the wear of the equipment and shorten its service life. Dust-free cutting can reduce the erosion of dust on equipment and extend the service life of the equipment.

[0006] ‌There are several ways to achieve dust-free cutting‌:‌ High-pressure water or air flow cutting‌: Cutting with high-pressure water or air flow will not generate dust. This method is suitable for certain specific materials and processes‌.‌ Local ventilation system‌: Install local ventilation equipment such as exhaust fans and ventilation hoods near the cutting head to collect smoke and dust by suction to reduce the concentration of smoke and dust in the air‌.‌ High-efficiency dust removal integrated system‌: Use special dust removal equipment, such as bag dust collectors, wet dust collectors, etc., to filter and purify the smoke and dust generated during the cutting process‌.

[0007] In summary, dust-free cutting has significant advantages in protecting the environment, ensuring workers' health, improving work efficiency and the quality of the working environment, and is one of the key measures to achieve green production and sustainable development.

[0008] For example, the application number 202321896968.8 involves the field of dust-free cutting technology, in particular, a dust-free cutting device, including a base plate, a cutting clamping structure is provided on the base plate, the cutting clamping structure includes a first shell, the lower surface of the first shell is fixedly connected to the upper surface of the base plate, the two limit rods are respectively slidably connected to the slideway processed on the inner wall of the first shell, the two clamps respectively penetrate the first shell and are slidably connected to the slideway processed on the first shell, through the cooperation of the cutting clamping structure and the base plate, the first motor is started to drive the lead screw to rotate in the first shell, the rotation of the lead screw drives the threaded seat to move downward, driving the clamps on both sides of the slideway processed on the first shell to slide relative to each other, and at the same time driving the limit rods on both sides to slide relative to each other on the slideway processed on the inner wall of the first shell, the workpiece is clamped and fixed by the two clamps, avoiding the use of manual rotation of the lead screw for clamping and fixing, thereby reducing manual labor.

[0009] However, most of the current dust-free cutting equipment cannot accurately adjust the position of the laser head from the workpiece for textile machinery metal parts of different diameters, and the cutting depth and cutting accuracy are not standard; the smoke adsorption effect is not good, the dust absorption effect is poor, and the smoke generated during the cutting process is not completely absorbed; when the equipment protection is opened for loading and unloading, the dust and smoke inside the equipment cause harm to workers; the replacement batches of adsorption consumables are high, the maintenance cost is high, the residue on the workpiece surface is not cleaned up, and the appearance quality of product cutting needs to be improved.

The pressurized smoke drives the adsorption shaft with the cylindrical adsorbent to rotate, and then is discharged after the square adsorbent; S6. When cutting starts, the scraper cylinder is actuated to push the pointed scraper close to the cutting seam, and the scraper blades arranged on both sides of the pointed scraper scrape the cutting residues on the workpiece on both sides of the cutting seam; S7, the workpiece is placed on the support wheels on the multiple groups of support wheel seats, the pressure wheel cylinder drives the pressure wheel seat to hinge and rotate on the feeding seat through the pressure wheel slide rod, drives the pressure wheel to press the workpiece, and the servo drive mechanism moves linearly along the axis direction of the hollow chuck to feed the material; S8, the slide cylinder drives the clamping plate to move left and right, the push rod cylinder drives the clamping plate to move up and down, the corner cylinder drives the clamping plate to rotate vertically, and the double-head cylinder drives the two groups of clamping plates to move closer or farther to transfer the workpiece; Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up the cutting fine-tuning mechanism, the position of the laser head from the workpiece can be accurately adjusted for metal parts of textile machinery of different diameters to ensure the cutting depth and cutting accuracy; through the design of closed profiles and cover plates, while ensuring the movement of the laser head, the sealing of the movement mechanism is guaranteed, thereby improving the service life of the equipment.

[0013] 2. By setting up an end-contact dust suction mechanism, the adsorption force is significantly improved compared with conventional dust suction mechanisms, and the smoke adsorption effect is significantly improved. In particular, the design of the vortex dust suction combination fan, through the vertical cavity formed between the vertical fan blades and the vortex cavity formed between the spiral fan blades, is connected to each other, and the narrow vortex rotates to form a high-pressure vortex airflow. Combined with the pressure-boosting capillary with reduced diameter, the suction force at the flat-mouth suction port is greatly improved, the dust suction effect is improved, and the smoke generated during the cutting process is effectively absorbed.

[0014] 3. By setting up a material discharge dust removal mechanism, the cutting waste is effectively blocked by the dust shield and falls into the material guide chute through the material discharge port. During the falling process, a small amount of smoke is accompanied by it, which is adsorbed by the material discharge dust removal mechanism, thus preventing the smoke from flowing out of the material guide chute and improving the overall dust-free effect of the equipment.

[0015] 4. By setting up a multi-channel negative pressure smoking mechanism, a small amount of smoke that is not absorbed stays in the protective cover and is adsorbed by the multi-channel negative pressure smoking mechanism, ensuring the effective absorption of smoke during the internal processing of the equipment, and ensuring that the inside of the equipment is dust-free and smoke-free when the equipment protection is opened for loading and unloading, effectively preventing the damage of cutting dust and smoke to humans.

[0016] 5. By setting up a self-rotating adsorption mechanism, when the pressurized flue gas passes through the self-rotating adsorption mechanism, the adsorption shaft drives the cylindrical adsorption body to rotate at the bottom of the adsorption box under the push of the adsorbed flue gas pressure, and the particles stuck on the cylindrical adsorption body are rubbed and vibrated to fall off, which effectively improves the service life of the self-rotating adsorption mechanism, reduces the replacement frequency, and reduces the maintenance cost.

[0017] 6. By setting up a follow-up scraping mechanism, a pointed scraper and a scraper blade, the scraper blades on both sides of the pointed scraper can symmetrically scrape the slag on both sides of the cutting seam, effectively removing the residue on the surface of the workpiece and improving the appearance quality of the product cut by the equipment.

[0018] 7. By setting up an auxiliary feeding mechanism, the feeding accuracy is effectively improved, and the servo drive mechanism is used for precise feeding, which improves the processing accuracy of the product.

[0019] 8. By setting up an automatic unloading mechanism, after cutting is completed, the material is clamped and placed on the unloading table by the automatic unloading mechanism, which is convenient for batch processing. There is no need to stop the machine many times for manual material removal, which wastes manpower, improves the degree of automation of the equipment, and at the same time reduces the labor intensity.
