Introduction to the process characteristics of forging
Modify metal structure, metal function. After the ingot is hot forged, the original as-cast looseness, pores, micro-cracks, etc. are compacted or welded; the original dendrites are broken to make the grains finer; at the same time, the original carbide segregation and unevenness are modified. Distributed to make the structure uniform, so as to obtain forgings that are dense, uniform, slender, good in analytical performance and reliable in use. After the forgings are deformed by hot forging, the metal is a fibrous structure; after deformation by cold forging, the metal crystals are ordered X2 metal plastic X The work is made into the desired shape of the workpiece.
After the metal is subjected to external force, the plastic X flow occurs according to the following rules:
One is the law of volume fluctuation. Except for the part that is intentionally removed, the rest of the metal is transferred to each other, and the entire volume remains unchanged;
The second is the law of small resistance, the metal always moves to the part with the small resistance. During consumption, the shape of the workpiece is often controlled according to these rules, and deformations such as upsetting and drawing, reaming, meandering, and deep drawing are realized.
The third is the size of the workpiece, which is not conducive to mass production of the structure. Die forging, extrusion, stamping, etc. use die to form accurate and stable dimensions. Forging machinery and automatic forging production lines can be used to structure mass or mass production.
The above information is collated by Henan Machinery Processing --- Luoyang Qinhan Seiko Co., Ltd. It mainly produces die steel, tool steel, ordinary carbon steel billets and processing with incoming materials, and the production capacity of a single piece can reach 25 tons. According to the customer's drawing requirements, we can undertake the production of die steel, shafts, gears, copper and aluminum and other forgings. Now it has developed into a modernized forging enterprise integrating forging, heat treatment and machining.
