It can realize isothermal hot forming forging press for hot sheet metal parts

Abstract

The invention relates to a forging machine capable of realizing constant-temperature thermal forming of hot metal sheet parts. The forging machine comprises a machine body, a working cylinder, a sliding block and a working platform, and is characterized in that the working platform is a movable working platform; the upper plane of the movable working platform and the lower plane of the sliding block are respectively and fixedly provided with a high-temperature-resistant metal cushion plate and a ceramic plate by fasteners in a one-step manner; the ceramic plate is internally provided with a heating unit; the lower plane of the ceramic plate of the sliding block and the upper plane of the ceramic plate of the movable working platform are respectively provided with a mold quick-clamping mechanism; and the periphery of the working area of the forging machine is provided with an insulating device. The forging machine has the advantages that the full maintenance of the temperature of the working area in the forging process under the high-temperature state can be realized, and the constant-temperature pressing of hot metal sheet parts is realized; the temperature loss is reduced to be the lowest, the energy can be greatly saved, the processing cost can be reduced, the forging quality and the production efficiency of a product are improved, and further the processing need to titanium-alloy constant-temperature thermal forming parts of airplanes in the aerospace industry is met.

Description

technical field [0001] The invention belongs to the technical field of forging machines, in particular to a forging machine capable of realizing isothermal thermoforming of hot sheet metal parts. Background technique [0002] In recent years, my country's aviation industry is developing rapidly. With the research and development of a new generation of fighter jets, helicopters, large aircraft, and high-performance engines, the manufacture of aircraft has put forward requirements for high thrust-to-weight ratio, high reliability, high durability, long life, and low cost. Therefore, the requirements for materials and processes The requirements are also constantly improving, and a large number of titanium alloys and high-temperature alloy materials are used. In particular, titanium alloy is the best structural material for the aviation industry because of its light weight, high strength, and good heat and low temperature resistance. [0003] At present, in the forging process...

AI Technical Summary

Problems solved by technology

The working area of ​​traditional forging equipment is an open structure. Due to the serious heat loss in the forging process of this structure, it is difficult for the forging temperature to reach an isothermal state; and the mold needs to be continuously heated to forge the next workpiece.

In addition, because the above-mentioned forging machines generally use manual replacement of molds, when the mold needs to be replaced, the operator needs to wait for the temperature of the forging press to drop to normal temperature before operating. After the mold is replaced and the workpiece is placed, the press needs to be reheated heat up and press

Due to the frequent replacement of the mold and the traditional manual clamping method, the heat loss of the press machine is serious, which not only wastes a lot of energy, affects the work efficiency, and increases the processing cost; but also makes forging more difficult and the yield is very low.

Therefore, the traditional forging processing machinery has been unable to meet the rapid development of the aviation industry
