Spiral blade 1, the main technology is continuous and so thick continuous cold rolling technology in order to make up for difficult molding specifications Jiangsu helical blade production, small batch debugging disposable material consumption and further improve the high precision molding helical blade research and development of new technologies. 2, and so thick technology to produce continuous helical blade and rolling technology to produce a helical blade pitch as much as continuous form, which is characterized by high precision molding, the thickness of the outer edge of the hole consistent thickness. 3, in the three helical blade molding material with the highest technology in Jiangsu helical blade technology, efficiency and continuous spiral shape quite cold rolling technology. Helical blades and other thick blade segment products and technologies: segmentation and other thick spiral blade "form a single pitch helical blade model, Jiangsu, almost the same thickness and the outer edge of the hole after forming an outer diameter of thickness, diameter, pitch can be accurately. meet customer desired size Ruifeng Accessories (Figure) |.
