Forging die for large hinge beam and production process of large hinge beam

Abstract

The invention discloses a forging die for a large hinge beam and a production process of the large hinge beam. The forging die is composed of a forging die lower die body and an upper die assembly. The forging die lower die body is composed of a bottom die assembly and a lower die assembly located on the bottom die assembly. The bottom die assembly is composed of a die pad, a bottom die, a big / small ear insert and a lower die insert. The lower die assembly is composed of a die body and an upper die insert. The upper die insert is arranged above the lower die insert and is fixed to the die body. The upper die assembly is composed of an upper flat die, an outer punch and an inner punch. A cutter is movably arranged on the side face of the big / small ear insert in a penetrating manner. The cutter comprises big ear cutter bodies and small ear cutter bodies, wherein the big ear cutter bodies are perpendicular to the small ear cutter bodies. By the adoption of the forging die for the large hinge beam and the production process of the large hinge beam, the situation of machining a hinge beam workblank by means of a traditional casting manner is changed thoroughly, and thus the problems that the hinge beam is poor in strength and short in service life are solved.

Description

technical field [0001] The invention relates to a forging die and a production process thereof, in particular to a forging die for a large hinged beam and a production process thereof. Background technique [0002] Since August 1965, when the No. 3 Grinding Institute of Jinan Casting and Forging Institute trial-produced my country's first 6×6MN (600 tons) DS-023 hinged six-sided top ultra-high pressure and high temperature synthetic diamond press, there have been more than 50 in my country. Years of production history of synthetic diamond presses. [0003] At present, the hinge beam parts of the six-sided top artificial diamond press are processed by castings, which have problems such as poor strength and short life; [0004] If the blank is processed by forging, there are the following problems: Taking the processing of φ650 hinge beam as an example, the required forging die is large and difficult to manufacture, and the weight of the whole set of φ650 hinge beam forging di...
