THE WIRE CLOTHES HANGER
THE WIRE CLOTHES HANGER
ANDREA RAMAZZINA 1156439A brief introduction: the historySome
historians believe President Thomas Jefferson invented a forerunner
of the wooden clothes hanger. However, today's most-used hanger,
the shoulder-shaped wire hanger, was inspired by a coat hook that
was invented in 1869 by O. A. North of New Britain, Connecticut
GeneralitiesThe wire clothes hanger is now used all over the
world and has several kind of users, from the big industries till
the common citizens. This is mostly because it has a good
mechanical characteristics at a really low production price.For
example for a small-medium quantity (100-500 hangers) the cost is
around 0.05 per piece.The structureThe structure of the wire
clothes hanger is really simple: it is a simple loop of wire, most
often steel, in a flattened triangle shape that continues into a
hook at the top.
First part: creating the wireStarting from cilindrics of steel ,
throught several processes of extruding and drawing, the thickness
of the wire decrease more and more.
A drawing machines with multiple draw mechanismThe shaping
process (1)When the wire reached the needed dimension, it is ready
to get in the clothes hanger machines. At first, it is cutted in
the volunted length, then it gets bent to form the base of the
hanger. The wire ends are now winded strongly in order not to let
the hanger open when it will be put under pressure.The final part
is bending one of the end, forming a hook.
The shaping process (2)As mentioned before, this process is
really simple and it takes only few seconds.Here is showed a video
to better understand the cutting and bending steps
