Three. Analysis of the causes of the accidents in the forge workshop 1. protection areas and equipment lack of protective devices and safety devices. 2. the protective device on the equipment is not perfect or not used. 3. the production equipment itself is defective or defective. 4. damage to equipment or tools and improper working conditions. There is something wrong with the 5. die and anvil. 6. confusion in the organization and management of the workplace. 7., the operation method and the assistant work of the repair are not done properly. 8. personal protective appliances such as protective glasses are faulty, work clothes and work shoes do not meet the working conditions. 9., when several people work together on a task, they do not coordinate with each other. 10. lack of technical, educational and safety knowledge, resulting in incorrect steps and methods.
4. the equipment used in forging production, such as air hammer, steam hammer, friction press, etc.. This equipment under impact load, prone to sudden damage itself (such as hammer piston rod suddenly broken) injuries caused by serious accidents. Press (such as water presses, crank hot forging press, forging machine, shearing machine, precision press) at work, although the impact is smaller, but the equipment suddenly damaged, have also occurred, the operator often be caught off guard, may also lead to accidents. 5. in the work force of forging equipment is very large, such as crank press, forging machine and hydraulic stretching machine this type of forging equipment, their working conditions are relatively stable, but the working parts of the power is great, as China has made and used 12000t forging hydraulic press. It is a common 100~150t press, and the force is already big enough. If the die is slightly incorrect when it is installed or operated, most of the force is not on the workpiece, but on the mold, tool, or device itself. In this way, some kind of installation adjustment error or improper tool operation may cause mechanical damage, as well as other serious equipment or personal accidents. 6. forging tools and auxiliary tools, especially in the hands of free forging and forging tools, clamps etc. these tools are a multitude of names, together in the workplace. In the work, tool replacement is very frequent, storage is often messy, which will increase the difficulty of these tools to check, when use a forging tool often can not be quickly found, sometimes "bad" use similar tools, so often cause accidents. 7. because of noise and vibration equipment forging shop in operation, the workplace noise affects people's auditory intolerable to the ear, and the nervous system, a distraction, thus increasing the possibility of accident.
Forging production risk factors and the main reason, in forging production, the traumatic accident prone, according to its causes can be divided into three kinds: first, mechanical injury by machine, tool or workpiece directly caused by scratches, bruises and burns; second; third, the electrical contact injury. Two, from the perspective of labor protection and safety technology, the characteristics of forging workshop: 1. forging production is carried out in the hot state of the metal (such as low carbon steel forging in the temperature range of 1250~750 DEG), because of the large amount of manual labor, a little careless may happen to burns. Heating furnace and hot forging workshop of 2. steel ingot, billet and forging constantly from a large number of radiant heat (forging in the forging at the end, still have very high temperature), workers often by thermal radiation damage. 3. heating furnace forging workshop produced in the combustion process of smoke into the air of workshop, will not only affect the health, but also reduce the visibility of the workshop (for heating furnace, solid fuel burning will be more severe), and may also cause accidents.
