2.2. THE COUNTRIES
WHERE THE BELARUSIAN EQUIPMENT WORKS
The
countries which use the offered equipment are
Belarus, Russia, the Ukraine, Bulgaria, Poland, the Czech Republic, Germany, Italy, Spain, Turkey, the USA, Mexico, India and South Korea.
2.3. FIELDS OF
APPLICATION.
The CWR is used in
automobile, machine-building, instrument-making,
agricultural machinery, tractor, aircraft
industries and in the atomic industry to machine
structural and a range of tool steels,
refractory steels as well as copper-,
aluminium-, titanium-, and zirconium-base
non-ferrous alloy. Configuration of rolled
details is very versatile: cylindrical, conical,
spherical surfaces with different ditches and
collars. The CWR method can be used in a
technological process for the production of
intermediate profiled blanks for the following
exact forming or in other processes of plastic
forming.

INTERESTING TECHNOLOGIES.
|
Synchronizer axle
for
tractorТs gear-box
|
Separate surfaces of a forging, received with
the method of cross-wedge rolling, are not
subject to mechanical processing
|
|
Chisel hammer lance
|
The following mechanical processing is
turning of the site |
|
Cutting tool of the mining machine
|
The working part of a cutting tool is subject
to laser alloying directly on rolled
surface |
|
A workpiece of a ball pin for light
automobile LADA
|
Two forgings are rolled simultaneously with
the division on the final stage of the rolling
process to lessen metal waste |
|
A workpiece of a ball pin for heavy
automobile MAZ
|
The technology includes heating, cross-wedge
rolling of an intermediate workpiece, and
subsequent forming on a mechanical press from
the same heating of a spherical part head; that
results in the production of workpieces without
waste |
|
Hydraulic equipment arm
|
Separate surfaces of a part, received with
the method of cross-wedge rolling, are not
subject to mechanical processing |
|
Ball
|
The initial rod without rotation is devided into cut-to-length sections with taper butts to reduce metal waste at cross wedge rolling. |
|
Railroad screw
|
Zonal heating of a workpiece with the
diameter of 24 mm and forming of a screw head,
then zonal heating and threading with the
diameter of 24 mm with the method of cross-wedge
rolling; that results in tool life of more than
500 000 units |
|
Spanner
|
The blank is rolled using the method of cross-wedge rolling to prepare it for further flash-free forging from the same heating. |
|
Chain ring
|
Using the method of cross-wedge rolling an accurate blank is prepared for further flash-free forging from the same heating. |
|
Horse shoe
|
With the method of cross-wedge rolling a
workpiece is rolled with the creation of an
eccentric for forming of horse shoeТs pin, then
a workpiece is curved and flash-free forming of
a horse shoe with a pin is
executed |
|
Bicycle connecting rod
|
A workpiece is heated, cross-wedge rolling of
an intermediate workpiece is executed, and then
with the same heating a flash-free forming of a
connecting rod is executed on a mechanical
press |
|
Workpiece for forming
|
A bar of unlimited length is heated in an
inductor and on the output from the inductor a
measuring workpiece is cut with the method of
cross-wedge rolling from a bar without rotation
for subsequent forming; the length of a
workpiece is significantly less than its
diameter, one butt-end of a workpiece can be
straight |
