Safety technical measures of forging machinery
1 risk factors of forging machinery
forging is one of the methods of metal pressure processing, and it is an important link in mechanical manufacturing production. According to the different temperature state of metal materials during forging processing, forging can be divided into hot forging, warm forging and cold forging after nylon moisture absorption. This paper refers to hot forging, that is, the forgings in which the processed metal material is in a red hot state (within the forging temperature range), and the metal is plastically deformed by the impact force or static pressure exerted by the forging equipment to obtain the expected overall size and organizational structure
the main equipment in the forging workshop includes forging hammer, press (hydraulic press or crank press), heating furnace, etc. Workers who add long carbon fibers to the mixture are often exposed to adverse working conditions such as vibration, noise, high temperature burning, smoke and dust, and stacking of heads and blanks. Therefore, special attention should be paid to the safety and health of workers who operate these equipment; Otherwise, various safety accidents, especially personal injury accidents, will easily occur in the production process
trauma accidents prone to occur in forging production can be divided into three types according to their causes:
(1) mechanical injury - scratches and bumps directly caused by machines, tools or workpieces
(2) scald
(3) electrical injury
2. Characteristics of the forging workshop
from the perspective of safety technology and labor protection, the characteristics of the forging workshop are:
(1) the forging production is carried out in the state of hot metal (for example, the forging temperature range of low carbon steel is 1250-750 ℃). Due to a lot of manual labor, burns may occur if you are not careful
(2) the heating furnace and hot ingots, blanks and forgings in the forging workshop constantly emit a large amount of radiant heat (the second temperature of forgings is still quite high at the end of forging), and workers are often affected by thermal radiation
good comprehensive performance (3). The smoke and dust produced by the heating furnace in the forging workshop during the combustion process is discharged into the air of the workshop, which not only affects the working environment, but also reduces the visibility in the workshop (for the heating furnace burning solid fuel, the situation is more serious), so it may also cause industrial accidents
