Description
Technical Field

Background
The helical blade is an important part in equipment such as a paver, a screw conveyor and the like, is mainly used for conveying compressible materials with high viscosity, and has the functions of stirring and mixing the materials in the process of completing conveying operation. The abrasive is worn and impacted in the process of mutual collision and extrusion due to direct contact with asphalt, rock and mixture, and the use condition is very bad. In many cases, the wear of the blades gradually spreads from the outer edge to the inside, exhibiting an uneven distribution characteristic.
In recent years, the problem of wear resistance of helical blades has become an increasing focus of attention and research. At present, the spiral blade is integrally formed mainly by a casting method. In the production, research and development processes, people often only pay attention to the wear resistance of the outer edge of the blade, and neglect the requirement of the use condition of the internal installation part. The wear resistance of the outer edge of the blade can be improved to a certain extent by adopting methods of adjusting the chemical component content of the blade, improving the blade casting process, optimizing the blade heat treatment process and the like, but the procedures are complex and complicated, the stability is not high, and the improvement effect is very limited. Meanwhile, the screw blade produced by integral molding has the same casting structure with the outer edge in the inner part, and the hardness of the material is greatly improved after heat treatment, but the abrasion resistance is increased and the risk of brittle fracture exists. In addition, in the working process, larger stone particles are always remained at the positions of the circular rings and the tile shaft openings which are arranged in the blades, and the circular rings and the tile shaft openings which are hard and brittle are easy to squeeze to generate cracks, so that early fracture and failure are easy to occur. In actual production, no matter the outer edge of the helical blade is worn out too early or the annular ring and the tile shaft mouth are broken too early, the equipment is required to be stopped and replaced again, so that the working efficiency of the equipment is greatly reduced, the labor intensity of workers is greatly increased, and time and labor are wasted.
Screw blades belong to multi-directional special-shaped complex section parts, however, no report on blade forming and performance improvement by adopting a precise extrusion process is currently seen. How to use the precision forming technology for the mass production and processing of the parts and simultaneously realize the preparation of parts by combining the metal material extrusion technology and the wear-resistant technology is an important research direction for the design and optimization of the material performance. Therefore, it is necessary to improve the structure of the traditional extrusion die and compound the structure with the material surface strengthening technology, so as to expand the application range and the application object of precise extrusion forming, and the structure is directly used for the industrial production of the multi-directional special-shaped section parts.
