Machining workers face a messy working environment, and it is indispensable for them to do a good job of safety protection. The mechanical production includes the production of various machinery such as transportation tools, machine tools, power machinery and precision instruments, usually casting and heat treatment. , Machining and assembly workshops, the types of work are thick and muddy, but the safety protection of workers is basically the same, because the elements of work damage are roughly the same. (Relatively speaking: CNC machine tools and CNC CNC machine tool assembly workshops are relatively clean, and other CNC machine tool processing workshops have casting, falling sand, and the working environment is messy)
1. The primary dust work for productive dust is casting. During the processes of molding sand manufacturing, molding, falling sand, sand cleaning, etc., the dust can fly, especially when sandblasting technology is used to repair the castings, the dust concentration is very high. The quartz used The damage is greater. In the process of machining, the polishing and polishing of metal parts can generate metal and mineral dust, which can lead to pneumoconiosis. During electric welding, the flux, electrode core and materials to be welded will evaporate at high temperatures to generate a lot of welding dust and harmful gases. Long-term inhalation of higher concentrations of welding dust can cause welders' pneumoconiosis.
The working environment faced by machining workers is messy, and it is indispensable for them to do a good job of safety protection. Mechanical production includes a wide range of machinery, including transportation tools, machine tools, agricultural machinery, textile machinery, power machinery and precision instruments. , Usually there are casting, casting, heat treatment, machining and assembly workshops, the types of work are thick and cloudy, but the safety protection of the staff is basically the same, because the elements of work damage are roughly the same. (Relatively speaking: CNC lathes and CNC lathe assembly workshops are relatively clean, and other CNC lathes and machining workshops are very casting, sand falling, and the working environment is messy)
2. High temperature and heat radiation The high temperature heat radiation of machinery manufacturing plants is mainly in casting, casting and heat treatment. The melting furnace, boring furnace, molten metal, hot castings in the foundry workshop, the heating furnace in the foundry and heat treatment workshop and the red-hot metal parts all have intense heat radiation, forming a high-temperature environment. Heatstroke occurs in severe cases.
3. In the process of noise vibration and ultraviolet mechanical production, the use of sand tamping machines, pneumatic tools, various forging hammers, grinding wheels, rivets, etc. can generate intense noise; electric welding, gas welding, sub-arc welding and plasma welding The occurrence of ultraviolet rays, if improperly protected, can cause electroophthalmia.
Faced with different types of work environment, the processing staff in the mechanical workshop need to choose suitable safety shoes according to the different working environment. For example, the casting workshop should wear high-temperature safety shoes because of iron filings and slag splashing; mechanical processing workshops have machinery Wear anti-smashing and anti-puncture safety shoes if the object falls and sharp objects pierce the sole of the shoe. Otherwise, you should wear suitable safety protective factory clothes and safety helmets for all protection according to your own needs.
