Heavy forgings are when large metals are pressed and shaped to their own ends. This force is typically achieved through the use of a hammer or pressure. The forging process builds a fine granular structure and improves the physical properties of the metal. In the real use of parts, a correct design can make the particle flow in the direction of the main pressure.
Heavy forgings should pay attention to the following points in the forging process:
1. The process should be complete:
Heavy forgings generally cut the material into the required size, heating, forging, heat treatment, cleaning and testing. Although the working conditions vary with different forging forms, they have certain common characteristics, such as moderate strength manual labor, dry and hot microclimate environment, noise and vibration, and air pollution by smoke. So in large forging workshops, Harm varies with different jobs, so it is necessary to operate strictly in accordance with the process.
2. Pay attention to safety:
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, resulting in thermal imbalance and pathological changes. The amount of sweat produced by 8 hours of labor will vary with the small gas environment, physical exertion, and degree of thermal adaptability. It is generally between 1.5 and 5 liters, or even higher. In a small forging shop or far away from the heat source, the heat stress index is usually 55~95, but in a large forging shop, the working point near the heating furnace or drop hammer may be as high as 150~190. Causes salt deficiency and heat cramps. Exposure to microclimatic changes during the cold season may promote adaptation to some extent, but rapid and too frequent changes may pose a health hazard.
