Development trend and processing method of forging parts
1. Forging. The utility model relates to a processing method for forging parts which have local or full plastic deformation of a blank and an ingot under the action of a pressing device and a working tool to obtain a certain geometric size, shape and quality. Forging includes free forging and model forging.
2, squeeze. With a strong pressure, the metal blank is extruded from the die hole of the extrusion die and the processing method of the desired product is obtained. Extrusion products have a variety of shapes and shapes, as well as the inner and outer rings of the bearing.
3. Rolling. The rolling force (friction) is used to deform the metal in the gap of the rotating roll to obtain a desired product processing method. The raw materials used in rolling production are mainly steel ingots, and the products are made of steel, steel and seamless steel.
4, Sheet metal stamping. The use of punching force or static pressure to press a metal sheet between the dies to produce a method of separating or forming to obtain a desired product.
5, drawing. The pulling force is used to pull the metal blank from the die hole and obtain a processing method of the desired product. Pull out cable products, thin-walled tubes and profiles of various special geometries.
Development trend of forging parts
1 Improve the intrinsic quality of forgings, mainly to improve their mechanical properties (strength, plasticity, toughness, fatigue strength) and reliability. This requires a better application of the theory of plastic deformation of metals; the application of materials with better intrinsic quality, such as vacuum treated steel and vacuum smelting steel; correct pre-forging heating and forging heat treatment; non-destructive testing of forgings more strictly and more extensively (See non-destructive testing).
2 Further development of precision forging and precision stamping technology. Less cutting is an important measure and direction for the machinery industry to improve material utilization, increase labor productivity and reduce energy consumption. The development of high-hard, wear-resistant, long-life mold materials and surface treatment methods for forging blanks will be beneficial to the expansion of precision forging and precision stamping applications.
3 Develop forging equipment and forging production lines with higher productivity and automation. Under specialized production, labor productivity is greatly increased and forging costs are reduced.
4 Development of flexible forging forming systems (application of group technology, rapid mold change, etc.), enabling multi-variety, small-batch forging production to utilize high-efficiency and highly automated forging equipment or production lines, making its productivity and economy close to large quantities. The level of production.
5 Develop new materials, such as powder metallurgy materials (especially double-layer metal powder), liquid metal, fiber reinforced plastics and other composite materials forging processing methods, and develop technologies such as superplastic forming, high energy rate forming, and internal high pressure forming. Third, the grading drying efficiency: grading drying efficiency According to the dust particle size or particle size range to calibrate the efficiency of the dryer is called grading efficiency, it refers to the amount of dust collected and imported within a certain particle size range The ratio of the total amount of dust.
