An Exposition to Acquaint the Trade with Epoch-Making Im­
provements and Equipment That Have Recently
A N event of unusual interest to the forging industry
will be the second exposition of forging machines
and bolt and nut machinery to be held
at the plant of the National Machinery Company, Tiffin,
Ohio, August 21 to 26 inclusive. The first exposition
of this kind, which was held by the same
company 15 years ago, met with such widespread approval
that they have decided to exploit recent improvements
in methods and equipment by a similar
demonstration.
The continually increasing field of application for
forgings has spurred the machine and die designer on
to new efforts, and no man who manufactures a product
of iron-or steel, whether he has spent years in
the forging business or never heard of a forging machine,
realizes the rapid strides that have recently
been made in machine forging.
While much has been accomplished in the line of
machine forging in the past, the possibilities have not
been fully realized. Steel, iron and malleable castings,
drop forgings and screwr machine parts are all products
which may be made cheaper or stronger by machine
forging. It is to acquaint the trade with the
possibilities of these new methods and designs that
this exposition is being held. All these designs are
new and embody features that have so widened their
scope that the "impossible job" of yesterday is the
"practical job" of today. No effort is being spared
to make clear to the visitor by actual demonstration
on a production basis how these ideas can be used to
improve his own processes.
A complete line of the "Company's new type high
duty forging machines, ranging from a small 1-in.
machine to a massive 5-in. machine, will be in operation
on a wide variety of intricate and interesting jobs.
Each machine will be producing a different forging,
and dies have been selected that will show all phases
of machine forging such as upsetting, expanding,
piercing, punching, etc. Full information will be
available on the various dies used, such as details of
design, kind of steel used, heat treatment, etc., also
data will be at the disposal of all interested on furnaces,
motors and other accessory equipment.
A complete bolt and nut plant will be in full swing.
New methods of heating—employing everything from
the oil-fired cut blank heaters to the electric heater,
will be demonstrated. Everything in the bolt heading
machine line will be shown in full operation, such
as high speed stop motion headers, automatic feed
"semi-hot" headers and hammer headers. The visitor
will see a small ^-in. automatic feed semi-hot
header making a big head carriage bolt at the rate of
200 per minute; a 1^-in. stop motion header making
machine bolts at a new high rate of production; hammer
headers and large size semi-hot automatic feed
headers making work that even the experienced man
will marvel at.
This extensive educational exposition represents a
great effort on. the part of the National Machinery
Been Developed in Machine Forging
235
Company and is a rare opportunity to investigate a
surprising number of new methods and machines not
previously shown. No user should disregard the
educational and economic value of this demonstration,
for more progress has been made in machine
forging in the last two years than is generally known,
even by the experienced man. Without doubt the
exhibit will be a long step toward a general utilization
of these improvements and in many cases will
serve to revolutionize processes.
It is doubtful whether an exposition of such magnitude,
with all equipment operating on a production
basis, has ever been offered to any branch of industry.
There will be 62 machines in operation, ranging
from a J^-in. nut tapper weighing 125 pounds to a
5-in. heavy duty forging machine with a weight of
130,000 pounds, 10 furnaces, 550 horsepower in motors
and other auxiliary equipment representing in all
$450,000.
The Master Blacksmiths' Association will hold its
annual convention at Cleveland, August 18, 19 and
20. This association as a body accepted an invitation
from the National Machinery Company during their
1924 meeting to attend this exposition, and Friday.
August 21, has been set aside as Master Blacksmiths'
Day. A large part of the work to be demonstrated
will be of extreme interest to members of this association
and no amount of effort will be spared to see that
their visit to the plant is both profitable and pleasant.
aA.s guests of the company, members and their families
will be brought down from Cleveland to Tiffin by special
train. During their visit lunch and dinner will be
served and at the conclusion of the trip they may
return to Cleveland by special train or depart for
their respective homes direct from Tiffin.
The exposition will be open to railroad and other
industrial executives and officials on August 24, 25
and 26, and those attending at this time will be guests
of the company during their stay in Tiffin.
It is the aim and hope of the company that the
educational value of this exposition will repay its
guests by giving them first-hand information on the
rapidly broadening field of machine forging. As announced
through other channels, the company extends
a cordial invitation to anyone who has problems
along this line.
Recommended Practices
The American Society for Steel Treating has issued
additional pages for its handbook of recommended
practices covering the heat treatment of 18
per cent tungsten high-speed steel, and for the heat
treatment of plain carbon tool steel. Copies of these
practices will be sent to the members of the Society
this month, and additional copies will be available to
those who desire them.
