Technical Field

[0002] Forging is a processing method that uses a forging machine to apply pressure to a metal blank to cause it to undergo plastic deformation in order to obtain a forging with certain mechanical properties, shape and size. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as cast porosity produced during the metal smelting process and optimize the microstructure. At the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than those of castings of the same material. Forgings are mostly used for important parts in related machinery with high loads and severe working conditions, except for simpler shapes that can be made of rolled plates, profiles or welded parts.

[0003] At present, most of the steel billet processing and forging devices on the market lack thermal insulation equipment. After the steel billet is forged and pulled out, the receiving temperature changes too much, causing cracks in the internal structure, affecting production efficiency. Summary of the invention
