(1) The forging production is carried out in the state of metal burning (such as the temperature range of low carbon steel forging is between 750~1 250 °C), due to a large number of manual work, burns may occur if you are not careful.
(2) The heating furnace and the scorching ingots, blanks and forgings of the forging operation constantly emit a large amount of radiant heat (the forging still has a fairly high temperature at the end of forging), and workers are often harmed by thermal radiation.
(3) The smoke and dust generated by the heating furnace of the forging operation during the combustion process are discharged into the air of the workshop, which not only affects hygiene, but also reduces the visibility in the workshop (for the heating furnace that burns solid fuel, the situation is more serious), and increases the possibility of accidents.
(4) The equipment used in forging processing, such as air hammers, steam hammers, friction presses, etc., is emitted by impact force when working. When the equipment is subjected to such impact loads, it is easy to be damaged suddenly (such as the sudden breaking of the forging hammer piston rod) and cause serious injury accidents. Presses (such as hydraulic presses, crank hot die forging presses, flat forging machines, fine presses), shearing machines, etc., although the impact is small, but sudden damage to the equipment also occurs from time to time, and the operator is often caught off guard, which may also lead to industrial accidents.
(5) The force of forging equipment in the work is very large, such as crank press, tensile forging press and hydraulic press, although their working conditions are relatively stable, but the force generated by their working parts is very large, such as the L2 000 t forging hydraulic press that has been manufactured and used in China. It is a common l00~150 t press, and the force emitted is large enough. If the mould is installed or operated incorrectly, most of the forces are not applied to the workpiece, but to the parts of the mould, tool, or equipment itself. In this way, some kind of installation adjustment error or improper operation of the tool may cause damage to the machine and other serious equipment or personal accidents.
(6) The tools and auxiliary tools of the blacksmith, especially the tools and clamps of hand forging and free forging, etc., are put together. In the work, the replacement of tools is very frequent, and the storage is often very messy, which inevitably increases the difficulty of checking these tools, and when a certain tool is needed in forging and cannot be found quickly, it is sometimes "improvized" to use similar tools, which often causes industrial accidents.
(7) Due to the noise and vibration generated by the forging operation equipment in operation, the working place is noisy, affecting people's hearing and nervous system, distracting attention, and thus increasing the possibility of accidents.
