According to the aluminum alloy forging learned from safety and labor protection point of view, forging is characterized by: (1) the forging production is carried out in metal hot condition (such as low carbon steel forging temperature in the range of 750 ~ 1250 DEG C), because there are a lot of manual work, a little careless may occur burns. (2), and the ingot blank forging heating furnace and hot forging operation, constantly sending out lot of radiant heat (forging in forging the end when, still has quite high temperature), workers often have the heat radiation of the infringement. (3) aluminum alloy forging heating furnace for forging operation called produced during the combustion process of smoke into the air of workshop, will not only affect the health, but also reduced the visibility (workshop for heating furnace burning solid fuel, the situation is more serious), increase the possibility of accidents. (4) using the forging processing equipment such as air hammer, steam hammer, friction press, work out the impact force. Equipment in the bear the impact load, is easy to sudden damage (such as hammer piston rod suddenly break) injuries caused by serious accidents. Press (such as water presses, crank hot die forging press, horizontal forging machine, precision press, shears etc.) at work, the impact is smaller, but the sudden damage equipment also have occurred from time to time, the operator often be caught off guard, may also lead to accidents. (5) force of forging equipment in work is great, such as crank press, forging machine and hydraulic tensile machine this kind of forging equipment, their work conditions are relatively stable, but the working parts of the generated power is great, as China has manufacturing and the use of L2 000 t forging hydraulic press. Aluminum alloy forging said is common l00 ~ 150 t press, the emitted power is big enough. If the mold installation or operation slightly incorrect, the majority of the force is not acting on the workpiece, but the effect in the mold, tool or device itself on the components of the. In this way, some kind of installation and adjustment on the error or the operation of the tool is undeserved, may cause mechanical damage and other serious equipment or accidents. (6) a blacksmith tools and auxiliary tools, aluminum alloy forging remind especially hand forging and free forging tools, clamps etc., these tools are put together. In the work, tool replacement is very frequent, storage is often very messy, this will increase the difficulty of these tools check, when forging a tool and need to quickly find, sometimes "make do" use a tool like this, often caused by inductrial injury accident. (7) as forging operation equipment generating noise and vibration in the operation, the working place is noisy, influence of human auditory and nervous system, distracted, thus increasing the possibility of accident. |
