There are many things to pay attention to heavy forgings, but not every item should be strictly paid attention to, what should be paid to heavy forgings in the forging process? The following article is mainly to tell you.
Heavy forgings are when large metals are pressured and shaped to their own ends. This force is typically achieved through the use of a hammer or pressure. The forging process builds a refined granular structure and improves the physical properties of the metal. In the practical use of parts, a correct design can make the particle flow in the direction of the main pressure.
Heavy forgings in the forging process should pay attention to the following places:
1, the process should be complete:
Heavy forgings generally cut the material into the required size, heating, forging, heat treatment, cleaning and inspection, although the working conditions vary according to the forging form, but has certain common characteristics, such as moderate intensity physical labor, dry and hot microclimate environment, noise and vibration, air pollution by smoke, so in the large forging workshop, The harm varies from job to job, so it is necessary to strictly follow the process.
2, safety should pay attention to:
Workers are exposed to high temperature air and thermal radiation at the same time, resulting in the accumulation of heat in the body, heat and metabolic heat, will cause heat disorders and pathological changes. The amount of sweat from 8 hours of labor will vary with the small gas environment, physical exertion, and the degree of thermal adaptability, generally between 1.5 and 5 liters, or even higher. In small forging workshops or far away from the heat source, the heat stress index is usually 55 to 95, but in large forging workshops, the working point near the heating furnace or drop hammer may be as high as 150 to 190. Causes salt deficiency and heat cramps. In the cold season, exposure to changes in the microclimate environment may promote adaptation to a certain extent, but rapid and too frequent changes may constitute a health hazard.
