Description

Technical Field

[0001] The invention relates to the technical field of stainless steel cutting, and in particular to a stainless steel rod bundle cutting device and method. Background Art

[0002] Traditional stainless steel rod bundle cutting methods mainly include mechanical cutting, flame cutting and band saw cutting. Mechanical cutting usually uses a cutting machine to cut the material through a high-speed rotating tool. Although the cutting machine can provide high-precision cutting when cutting stainless steel rods, it also has some disadvantages. First, the high hardness of stainless steel leads to accelerated tool wear and frequent tool replacement, which increases maintenance costs and downtime. Secondly, during the cutting process, a high cutting temperature may be generated, resulting in thermal deformation or stress concentration, affecting the cutting quality. In addition, the metal chips and smoke generated during the cutting process may pollute the operating environment, increasing the complexity of the cleaning work. For thicker stainless steel rods, cutting The speed may be limited, reducing production efficiency; flame cutting will also produce a larger heat-affected zone, which may cause local deformation and stress concentration of stainless steel, thus affecting cutting accuracy and material properties. Moreover, this cutting method is prone to produce an oxide layer, which requires subsequent treatment to ensure the quality of the cross-section. In addition, a large amount of smoke and harmful gases will be released during the flame cutting process, polluting the operating environment and increasing health risks. Band saw cutting of stainless steel bars is also prone to tool wear, increasing the maintenance cost of frequent tool replacement or adjustment. The cutting process produces more metal chips, requiring additional cleaning work, which increases the difficulty of operation. When cutting thicker stainless steel bars, the band saw cutting speed is relatively slow, affecting production efficiency. Summary of the invention
