Forging device for special material forge piece of maritime work equipment and forging method of forging device

Abstract

The invention relates to the technical field of forging, in particular to a forging device and a forging method for a special material forge piece of maritime work equipment, the forging device comprises a ring forging replacing mechanism, the ring forging replacing mechanism comprises a forging table, an outer anvil piece, a clamping anvil piece and an inner anvil piece, and the outer anvil piece, the clamping anvil piece and the inner anvil piece slide on the forging table in a collinear mode. The outer anvil piece comprises an outer anvil wheel rotating on the forging table, and the outer anvil wheel comprises a special-shaped wheel used for extruding the outer side of the forged piece to be forged. The inner anvil wheel of the clamping anvil wheel is tangent to the inner side of the to-be-forged forge piece, the rotating inner anvil wheel moves in the direction away from the clamping anvil wheel, meanwhile, the pressing disc is matched with the inner tray and the outer anvil wheel, horizontal outward ring expansion forging of the to-be-forged forge piece is achieved, rotation of the to-be-forged forge piece is conveniently controlled, the operation degree is low, and the forging efficiency is high. And meanwhile, the to-be-forged forge piece is gradually expanded outwards, so that extrusion forming of the to-be-forged forge piece by the pressure plate and the inner tray is facilitated, extrusion forming of the outer side of the to-be-forged forge piece by the outer anvil wheel is facilitated, and the forging efficiency and the forging effect are improved.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forging device and a forging method for special material forgings of marine engineering equipment. Background technique [0002] The ocean is salty, which is highly corrosive to metal materials. In order to ensure the service life of special metal materials for marine equipment in the ocean, metal materials are usually forged into special forgings by forging. At present, offshore wind power projects have become the current hot investment field, and offshore replacement rings are mainly used in offshore wind power projects. Because the forgings of offshore replacement rings have a large outer diameter of the flange section and a small length, a straight section wall thickness, and flanges Due to the large step difference from the straight section and the difficulty of forging, its copy forging and high-quality and efficient production have become the current research and develop...

AI Technical Summary

Problems solved by technology

[0005] It tilts the ring billet for forging, and the rotation axis of the ring billet is not parallel to the rotation axis of the support block. Not only the rotation of the ring billet is difficult to control, but also the operation is difficult, thereby reducing the forging efficiency
