The molding technology (inventory name: method of forming spiral section blades, patent number: ZL200810023870.5) which holds the national patent for invention was industrialized in 2004.This product has been awarded" China Jiangsu Province Hi-tech Products".
1. It is a proprietary technology developed to solve the difficulty of continuous rolling forming technology in large diameters, large thicknesses, special specifications and dimensions, and wear-resistant materials, stainless steel materials, etc., which are difficult to form with continuous rolling technology;
2. "Segmented equal-thickness spiral blade" is a single-pitch shape, and the thickness of the outer edge is almost the same as that of the inner hole. After molding, the outer diameter, inner diameter, and pitch can accurately reach the size required by the customer;
3. It can be formed over-large and over-thick, made of low-carbon steel, low-alloy steel, wear-resistant steel, and stainless steel with equal diameter, equal pitch, variable diameter, variable pitch, and inner hole circumference and outer diameter circumference with bosses or gaps Various forms of "segmented equal-thickness spiral blades" as required;
4. Good forming accuracy and high qualified rate of finished products, which can meet the requirements of small batch and individualized supply. It is especially suitable for the production of "spiral blades" of large specifications, large thickness and wear-resistant steel and stainless steel materials.
5. Material utilization rate and forming efficiency are lower than continuous cold rolling forming technology.
Low carbon steel, low alloy steel, wear-resistant steel, stainless steel, etc.
Within the scope of meeting the following table, customized production according to customer requirements.
