Description

Descaling hydraulic device for forging

Technical Field

The invention relates to the field of forging, in particular to a descaling hydraulic device for forging.

Background

The forging is a processing method which applies pressure to a metal blank by using a forging machine to enable the metal blank to generate plastic deformation so as to obtain a forging with certain mechanical property, certain shape and certain size, one of two major components of the forging (forging and stamping) can eliminate the defects of casting-state looseness and the like generated in the smelting process of metal through forging, optimize a microstructure, and meanwhile, as a complete metal streamline is saved, the mechanical property of the forging is generally superior to that of a casting made of the same material, important parts with high load and severe working conditions in related machinery are important, and except for a plate, a section or a welding piece which has a simple shape and can be rolled, the forging is mostly adopted.

The oxide skin is a corrosion product formed by oxidation of steel at high temperature, and consists of ferrous oxide, ferroferric oxide and ferric oxide, and comprises the following components from inside to outside: ferrous oxide, ferroferric oxide and ferric oxide, wherein the ferrous oxide has a loose structure and a weak protection effect, while the ferroferric oxide and the ferric oxide have compact structures and good protectiveness, and the measures for reducing metal oxidation are as follows: when the material temperature is below 1000 ℃, oxidizing furnace gas can be adopted, so that the formed oxide skin is easy to remove, and the temperature is not high at the moment, and the oxidation is not violent; when the material temperature is above 1000 ℃, reducing furnace gas is adopted, and the amount of air entering the furnace is reduced so as to avoid excessive oxide scale generation.

In the forging process, the contact of the oxygen in forging blank after the heating and the air can generate one deck cinder, if not in time clear away the cinder, pockmark, pit will appear in the forging surface, can imbed inside the steel billet even, produce adverse effect to the forging quality, become the waste product even, so at forged in-process, need in time clear away the cinder on workpiece surface. The existing technology for removing the oxide skin mainly uses acid (alkali) washing, manual work or high-pressure water, and the use of acid washing has influence on the environment; the efficiency of manually removing the oxide skin is low, and an operator needs to wear the thermal insulation suit to work in a high-temperature environment for a long time; the removal by high pressure water reduces the initial forging temperature and affects the quality of the finished product.
