Explain the function of the following components with reference to sheet metal shearing dies:

a) pilots, b) Stock stop.

Solutions

Expert Solution

Pilots :-

Pilots are playing key role in doing operation on multiple dies and we can trace the faulty design existed in press lines. Or Pilots In Progressive dies are used in order to get back the stock into the correct position for successive operations i.e. blanking or Piercing operations.

While applying the pilots, they must and should strong enough so repeated shock will not cause any fracture the dies.

And also the main purpose of pilots is the pilot positions the stock strip relation with die opening.

Stock Stop :-

it was required only when the stock is fed manually. Here the strip of sheet metal is going to fed and guided through a slot in stock guide. After each blanking the given strip has to advanced a correct distance. So achieve this type of device is called stock stop.

Please explain in manual written format and EXCEL function. Mercury is a heavy metal that can cause severe health problems in even small concentrations. Fish and shellfish efficiently concentrate mercury into their flesh, so it is important to monitor seafood for its mercury content. An extensive study conducted in 1980 concluded that the mean mercury level in oysters from the White Bear Estuary was .020 parts per million (ppm) with a population standard deviation , σ, of .022 ppm. In...
