Introduction to the characteristics of multidirectional die forging process

Multidirectional die forging is a process for forming and processing metal materials, which is usually used to manufacture large, complex shaped parts, such as those in the aerospace, automotive and energy sectors. In multidirectional die forging process, a metal billet is plastically deformed in a mold by applying forces in multiple directions to eventually form the desired shape. This process provides higher forming capacity and more complex geometries, and is more flexible than the traditional unidirectional die forging process. The main process characteristics of multidirectional die forging are as follows:
High material utilization, compared with open die forging, no waste of flying material, the shape of the forgings can be designed as hollow, and eliminate or reduce the punching of the die forging slope, thus saving 30% -50% of the metal.
Forging performance is good, because most of the shape of the forgings are formed by die forging, its fiber organization along the distribution of the contour of the forgings, so the mechanical properties of the forgings are good, general strength can be increased by more than 30%.
Suitable for high-alloy steel and special alloys forming, forging, due to the billet in the three-way compressive stress deformation, improve: its process plasticity, greatly facilitating the poor plasticity, forging temperature Fan Wang narrow high-alloy and special alloy materials forming.
High productivity, compared with the ordinary die forging, the number of steps used can generally reduce the number of 50%, so greatly reducing the forging time, a greater increase in production efficiency.
Wide applicability, can be used for all kinds of alloy hollow frame, solid and hollow branch and bud forgings, fork forgings, cylindrical parts, a variety of valves, pipe fittings and shaft forgings.
Multidirectional die forging belongs to the closed die forging, and forgings without flying edges, forgings of more internal shape can be obtained by forging, so the requirements of billet under the high precision, and at the same time requires the use of less, non-oxidizing heating. In addition, multi-directional die forging requires good rigidity, high precision of the special multi-directional die forging hydraulic press or in the general equipment attached to a special complex structure of the die forging device, but the equipment and devices need to be expensive.
