Description

Technical Field

[0001] The invention relates to the technical field of metal tube processing, in particular to a device for laser blanking of round tubes. Background Art

[0002] With the continuous advancement of industrial automation technology and the growing demand for precision manufacturing, the metal pipe processing industry is facing unprecedented challenges and opportunities. Especially in the field of food-grade pipe processing, due to the strict requirements on product surface cleanliness and hygiene standards, traditional cutting and cleaning processes can no longer meet the high-quality needs of the current market. Therefore, exploring and developing a round tube laser blanking equipment that can achieve efficient and clean cutting is of vital importance to improving production efficiency and ensuring product quality.

[0003] The rise and application of laser tube cutting technology

[0004] Laser tube cutting technology, as an innovative technology in the field of modern metal processing, can quickly and accurately cut various metal materials with its high energy density laser beam. This technology focuses the laser beam to a tiny spot through an optical system, causing the material to melt or vaporize at high temperature in a very short time, thereby achieving fast and accurate cutting. The significant advantages of laser tube cutting technology include: high efficiency, suitable for mass production; high precision, ensuring excellent cutting edge quality and small heat-affected zone; and flexibility, which can be widely used in a variety of metal materials such as stainless steel, carbon steel, and aluminum alloy.

[0005] The particularities and challenges of food grade pipe processing

[0006] Food-grade pipes are key components for transporting hygienic fluids such as food and beverages. Their surface cleanliness is directly related to the safety and sanitary quality of the product. However, traditional processing methods have many disadvantages in the process of pipe handling, cutting and cleaning. First, the direct contact between workers' gloves and pipes can easily lead to oil contamination. These oil stains are not only difficult to remove, but may also absorb impurities such as dust and dirt, causing corrosion to the surface of the pipe, thereby affecting the accuracy and effect of laser cutting. Secondly, the separate processing of cutting and cleaning processes not only increases the complexity and time cost of the production process, but also reduces the overall production efficiency.

[0007] Limitations and shortcomings of existing technologies

[0008] Although small-diameter laser tube cutting machines are now available on the market and have met some of the needs of metal tube processing to a certain extent, these devices still show many limitations in the field of food-grade pipe processing. Specifically, the existing equipment performs poorly in terms of material storage capacity, and the material rack storage capacity is limited, resulting in frequent replenishment of raw materials, increasing the complexity of operation and the cost of manual intervention. In addition, the cutting length is limited, and the cutting task of longer round tubes cannot be completed in one go, which seriously restricts its application potential in the processing of large-size workpieces. More importantly, due to the superposition effect of the above-mentioned factors, the overall processing efficiency of existing equipment is difficult to be satisfactory, and it cannot meet the urgent needs of modern manufacturing for efficient and continuous production.
