What are the precautions for forging?

Give us a brief introduction about what precautions for forging processing

1. The forging process includes: cutting the material into the required size, heating, forging, heat treatment, cleaning and inspection. In small manual forging, all of these operations are carried out by a few blacksmiths in the narrow place. They are exposed to the same harmful environmental and occupational hazards; in large forging workshops, the hazards vary from job to job. Working conditions Although working conditions vary depending on the form of forging, they have some common characteristics: moderate-intensity physical labor, dry and hot microclimate, noise and vibration, and air pollution by smoke.

2. Workers are exposed to high temperature air and heat radiation at the same time, which causes heat to accumulate in the body. Heat and metabolic heat will cause heat loss and pathological changes. The amount of sweat per hour of labor will vary from 1.5 to 5 liters, or even higher, depending on the small gas environment, physical exertion, and degree of thermal fitness. In the smaller forging workshops or farther away from the heat source, the Beha Ershi heat stress index is usually 55 to 95; but in large forging workshops, the working point near the furnace or the drop hammer machine may be as high as 150 to 190. Easy to cause salt deficiency and enthusiasm. In the cold season, exposure to changes in the microclimate may promote adaptation to a certain extent, but rapid and too frequent changes may constitute a health hazard.

Aluminum forgings manufacturers indicate noise and vibration: the hammer will inevitably produce low frequency noise and vibration, but it may also have a certain high frequency component with a sound pressure level between 95 and 115 decibels. Exposure of workers to forging vibrations can cause temperament and functional imbalances that can reduce work capacity and impact safety.
