Occupational Safety Analysis and Current Trends of its Increase for Personnel of Hammer-Action Forging Machines Based on Vibrational Factor



Annotation:

The issues of improving occupational safety based on the vibrational factor when operating hammer-action forging equipment have been considered. The main attention has been paid to the assessment of the vibrational activity of stamping and forging hammers. It has been specified that today, vibration-insulating units for stamping and forging hammers have been developed, but these have significant flaws preventing their wide use. Up-to-date vibration-insulating units for stamping and forging hammers that ensure increasing occupational safety for personnel are proposed. The importance of the improvement of working conditions based on the vibrational factor at workplaces in forging shops has been substantiated. The results of studies of vibrational activity at the design of vibration-insulating units of a 5-ton stamping hammer and a 3-ton forging hammer as typical examples of shock-action equipment have been presented. In order to reduce vibrations of such equipment, multi-leaf springs that efficiently reduce vibration and can be operated on a long-term basis have been proposed for use. The efficient operation of a vibration-insulating structure of a stamping hammer is ensured when the springs are installed directly under the stock anvil. For vibration-insulating structures of forging hammers, the machine with racks is mounted on an intermediate frame supported by springs in the foundation pit. The frame prevents the hammer from swinging and ensures even loading of springs. The parametrical analysis of vibration-insulating units has demonstrated that by changing the rigidity of shock absorbers, it is possible to reduce the vibrational activity of machines to align it with sanitary norms. Recommendations on the use of shock absorbers in forging shops have been provided.
