Abstract
Description
Technical Field
[0001] The invention relates to the technical field of laser cutting equipment for carbon steel metal accessories, in particular to laser cutting equipment for carbon steel metal accessories. Background Art
[0002] In the manufacturing industry, processing carbon steel metal accessories is a common process, and laser cutting, as an efficient and precise processing method, is widely used in the cutting and forming process of carbon steel metal accessories.
[0003] Currently, when performing laser cutting operations on carbon steel metal accessories, the usual operation method is to place the carbon steel metal accessories on a needle-shaped workbench. The original intention of the design of the needle-shaped workbench is to allow the laser to pass through the gaps in the workbench during the cutting process, so as to facilitate the flexible cutting of carbon steel metal accessories of different shapes and thicknesses, and at the same time allow some of the heat generated during the cutting process to be dissipated.
[0004] However, in actual cutting operations, this traditional workbench setting brings a series of problems. When the laser acts on carbon steel metal accessories for high-speed cutting, a large amount of debris is generated. Due to the impact force and heat during cutting, these debris will scatter and spread across various parts of the needle-shaped workbench. Due to the special structure of the needle-shaped workbench, there are many tiny needle-shaped protrusions and gaps on its surface, which makes it very easy for debris to get stuck in the gaps between these needles and difficult to clean. Operators often need to spend a lot of time and energy using various cleaning tools, such as brushes, to barely clean the debris on the workbench, which greatly reduces production efficiency. It is also difficult to ensure thorough cleaning. Residual debris may also interfere with subsequent cutting tasks and affect cutting quality.
[0005] In addition, smoke is inevitably produced during the laser cutting process of carbon steel metal accessories. The smoke is mainly composed of metal vapor, oxide particles and organic combustion products. Since the area near the cutting table is usually the operator's working area, the smoke is diffused in the air and can be easily inhaled into the lungs by the operator. Long-term exposure to this environment will seriously threaten the health of the operator, and may cause respiratory diseases, pulmonary fibrosis and other health problems, bringing huge health risks to the operator. It also increases the hidden dangers and potential compensation liabilities of the enterprise in occupational health and safety. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The present invention proposes a laser cutting device for carbon steel metal accessories. When cutting the carbon steel metal accessories, the carbon steel metal accessories are first placed on the nail bed, and then the first screw motor is started to drive the first screw to rotate, so that the support frame slidingly connected to the first screw starts to slide, and the support frame drives the cylinder connected to the sliding block on the top of the support frame to move synchronously when sliding, and makes the laser cutting assembly connected to the telescopic rod at the bottom of the cylinder horizontally parallel to the carbon steel metal accessories. While the support frame slides, it drives the debris collection assembly to slide synchronously through the second connecting plate, so that the debris collection assembly is placed at the bottom of the carbon steel metal accessories. Then, by starting the second screw motor, the second screw motor drives the second screw to rotate, so that the sliding block on the second screw slides according to the required cutting position of the carbon steel metal accessories, so that the laser cutting assembly connected to the bottom of the cylinder is perpendicular to the required cutting position of the carbon steel metal accessories. Then, the cylinder drives the telescopic rod to extend and retract, so that the telescopic rod drives the laser cutting assembly to descend, and starts cutting the carbon steel metal accessories. At the same time, a protective cover connected by a spring on the outer side of the first connecting plate at the top of the laser cutting assembly completely covers the switching area of the carbon steel metal accessories, preventing the debris generated by the cutting from splashing around the cutting table and preventing the smoke generated by the cutting from spreading. By squeezing the spring, the cutting head at the bottom of the laser cutting assembly can contact the carbon steel metal accessories. After that, the debris generated by the cutting falls into the debris collection assembly through the through holes opened between the multiple groups of needles in the nail bed, and slides through the arc surfaces on both sides of the debris collection assembly to the storage box in the mounting groove in the middle of the bottom of the debris collection assembly. The storage box collects the debris. At the same time, the vacuum pump starts to pump air through the main vacuum pipe, so that the main vacuum pipe synchronously pumps air to each group of vacuum pipes through the connecting pipe. The top of the vacuum pipe pumps air, generating suction in the middle of the debris collection assembly, and the smoke generated by the cutting is sucked into the vacuum pipe along the through holes opened between the needles of the nail bed, and is absorbed by the activated carbon plate in the slot in the middle of the connecting block, so that the smoke is purified and discharged through the air pump connected to the main vacuum pipe.
