Description
Technical Field
[0001] The present invention relates to the technical field of LNG stainless steel pipe fitting processing, in particular to a forming device and method for processing LNG stainless steel pipe fittings. Background Art
[0002] LNG stainless steel pipe fittings, due to their excellent properties such as corrosion resistance, high temperature resistance, and high tensile strength, are widely used in various fields such as chemical, petroleum, pharmaceutical, and food. They play a particularly important role in the storage and transportation of LNG (liquefied natural gas). In the production and processing of LNG stainless steel pipe fittings, port polishing plays a vital role in the molding process and is an extremely critical step. This process not only involves the meticulous treatment of the material surface but also directly affects the quality and performance of the final product. Through precise polishing technology, the size and shape of the port can be ensured to meet the design requirements, thus ensuring the smooth operation of the entire molding process. The accuracy and quality of the port polishing determine the overall performance and service life of the product. Therefore, attention to the port polishing step is indispensable throughout the entire manufacturing process.
[0003] Compared with the existing technology: In the existing technology, if shaking occurs during the grinding operation, the grinding force cannot be maintained uniformly. This uneven grinding force will cause defects such as unevenness and wavy shapes on the surface of the pipe end. These defects will seriously affect the flatness of the pipe end, making it impossible to achieve the ideal surface quality. In addition, due to the lack of rotary grinding function, some parts of the pipe end may not be fully polished, resulting in burrs. These burrs not only affect the overall appearance of the pipe, but also may scratch other components or seals during subsequent use, thereby affecting the performance and life of the entire equipment.
