Press Construction Details and Description
13
910 MT Press Extrusion Line
MACHINE DESIGN The press is a three-column type
with a transverse die-slide. It utilizes one
billet container that is shifted by means of
hydraulic cylinders. It also includes all other
devices necessary for aluminum billet extrusion
(see list of relevant alloys). The press
comes complete with adjustment devices necessary
for the exact alignment of the press components.
They are designed to assure continuous alignment
during operation. The above mentioned devices
are particularly useful for the container, the
container holder, and the die slide, which are
heated components, and are free to expand without
causing any distortion or misalignment. Special
care has been taken in the design to guarantee
both a long press life, and ease of maintenance.
Wear-parts are self adjusting, so even after many
years of operation, no mechanical machining or
replacements are necessary.
14
910 MT Press Extrusion Line
MAIN CYLINDER RAM The main cylinder is made of
forged steel (single piece) with welded
extensions. It has been thoroughly tested,
including a pressure test to 150 of the rated
pressure. The cylinder is equipped with long,
bronze bushings so that the ram is properly and
precisely guided. The main cylinder is fixed
at the baseframe end. Concerning the extensions,
either the three main columns, or the two main
ram-advancing and returning hydraulic cylinders,
are fixed. The ram is made of wear-resistant
cast iron. Its surface is accurately lapped.
15
910 MT Press Extrusion Line
AUXILIARY CYLINDERS (for the rapid advance and
return of the main ram) Two forged-steel side
cylinders are provided for rapid advance and
return of the main ram. These cylinders are of
the double-acting type. Cylinders and piston
rods are made of a forged-steel integral
construction, with a wear-resistant bronze
face. The two stems are fixed, and they work on
the moving crosshead. In order to obtain the
presss rated capacity, the auxiliary cylinders
and the main cylinder must work at the same time.
16
910 MT Press Extrusion Line
PLATEN The extrusion platen is made of a
quality, high-grade steel. The platen bore is
wide enough to provide access to the extrusions
coming out of the die, and to ease the discharge
of partially extruded billets. The platen is
mounted on the baseframe in such a way that it is
longitudinally adjustable in order to assure
its correct positioning under pressure. A
high-strength pressure plate exists on the
internal face of the platen. This plate reacts
against the die tooling set, and the horizontal
shear load.
17
910 MT Press Extrusion Line
MAIN COLUMNS AND NUTS The main columns are made
of forged steel. They are designed to assure a
very high stiffness between the main cylinder and
the platen. Special split-nuts allow for the
pre-stressing of the columns position, and makes
possible the permanent locking of tie rods and
nuts during the final assembly of the
press. Thread design is of special type, and
the entire design is carefully worked out to
minimize stress concentrations and fatigue
conditions.
18
910 MT Press Extrusion Line
BASEFRAME AND GUIDES The heavy-duty baseframe
is a rigid, uni-body steel structure. It was
stress relieved before machining. All the guides
for the press members are carefully and
accurately finished to close dimensional
tolerances. The guides are of a reverse V
type and are provided with hard, renewable, and
adjustable wear plates.
19
910 MT Press Extrusion Line
MOVING CROSSHEAD The moving crosshead is
designed in such a way to assure a lasting
alignment of the extrusion stem with the press
centerline. The press columns support and
guide the crosshead using bronze plates. The
crosshead is stiffly fixed to the main ram, and
to the auxiliary cylinders.
20
910 MT Press Extrusion Line
EXTRUSION STEM The extrusion stem is centered
(and stiffly fixed) on the moving crosshead using
bolts. The heavy heat-treated alloy-steel
bolster is inserted between the bottom extrusion
stem and the moving crosshead.
21
910 MT Press Extrusion Line
DIE SLIDE The die slide is a transverse-type,
and is shifted by means of an oil-hydraulic
cylinder. It consists of two detachable
die-carriers. The first one is used as die
holder. The second one is provided with a
clearance hole for billet-sticker removal. This
hole contains a tempered-steel ring. A
tooling set (with the die included) is located in
the die-slide housing. The included pressure
rings are designed to take up, and transmit, the
extrusion force to the extrusion plate. The die
slide does not experience the extrusion force.
The die-slide shifts on a sturdy guide. It
bears on bronze wear-surfaces, which can be
easily replaced. The guide assures an effective
support, so as to prevent misalignment of the
tooling set, which is subjected to the cutting
loads of the main shear, and to the opening and
closing of the container.
22
910 MT Press Extrusion Line
DIE SLIDE The main shifting slide oil-hydraulic
cylinder is used to drive the auxiliary shear
for cutting the extrusion behind the die. The
tooling set is bearing against a sturdy
forged-steel bolster, which is fixed in the
reaction plate hole. The die assembly can be
aligned and centered in the press by adjusting of
the die slide. This can be realized vertically
by utilizing a wedge, and horizontally by means
of an adjustable positioning stop, which limits
the die shift stroke. The die slide consists of
a rugged unit, which is well guided and easy to
adjust. It is therefore possible to compensate
readily for both wear and temperature
differences, and perfectly centerline the die.
Positioning is simple, and deflections are
minimized, which results in optimum conditions
for long tool life, and for high quality of the
extrusion.
23
910 MT Press Extrusion Line
DIE CHANGING DEVICE The die-changing device is
composed of two housing shuttles situated on the
side of the press and driven by an oil-hydraulic
cylinder. Such a device allows for die changing
only from one side of the press. When such
changing is requested, the die slide shifts
laterally in such a way as to position the die
set over the empty shuttle housing. The used
die set detaches from the die slide by means of
the shifting shuttle, while the new one (which
is in the other housing) is prepared. During
the die-change operation, the die slide shifts
laterally until the die is positioned at the
center of the press. Two jig locaters are used
in order to assure the centering of the die at
the press centerline.
24
910 MT Press Extrusion Line
CONTAINER The container is centered in its
housing on the three keys located on the
vertical and horizontal centerlines of the
press. Uniform expansion under the influence of
heat is thus assured. The container is thus
automatically aligned by proper adjusting of the
housing. The container is held within the
housing by means of a split-hinged ring. The
ring is equipped with pull handles for fast
unlocking and relocking of the container, thus
permitting its rapid removal from its housing by
the main moving crosshead.
25
910 MT Press Extrusion Line
CONTAINER HOLDER The container holder is made
of a steel casting. Its design is such that it
will be as symmetrical as possible in order to
permit uniform radial expansion under the
influence of heat. The container holder is
supported and guided by two lateral prismatic
guides, which are part of the baseframe, and
lined with replaceable steel wear plates. In the
extrusion position, the container is sealed
firmly and squarely against the tool stack to
prevent flashing of material.
26
910 MT Press Extrusion Line
CONTAINER SHIFTING CYLINDERS The container is
operated by means of two shifting cylinders,
located symmetrically about the machine center.
The construction of these cylinders is similar
to that one of rapid advance and return
cylinders. The traveling stroke is controlled at
low pressure by means of a special interlock
circuit this prevents, in the event of any
obstruction of container path, the developing of
forces which could cause cocking or tilting of
the container or even bending the cylinder
rods. While the container is closed against the
die slide, a small volume and high pressure pump
assures a tight and effective sealing at the die
end.
27
910 MT Press Extrusion Line
VERTICAL BUTT SHEAR A heavy oil-hydraulically
operated shear is located above the press and is
mounted on the platen by means of a rigid
structure. Its function is to separate the butt
end from the extrusion. The shear cylinder is a
double-acting type. The sliding carrier of
the shear operates in a heavy housing and is
accurately guided in bronze wear liners, assuring
straight line, non-deflecting operation when
shearing.
28
910 MT Press Extrusion Line
HORIZONTAL AUXILIARY SHEAR The die slide
shifting cylinder has sufficient capacity to
function as a shearing device for cutting
extrusions behind the die, by transverse
movement of the die slide. The platen insert,
which acts as a shearing face, is adequately
hardened to withstand the shearing action.
29
910 MT Press Extrusion Line
BILLET LOADER The billet is charged into the
centerline of the machine by means of a loader
(of the pivoted swinging type) and pushed into
the container by the advancing pressing-stem.
The billet loader is composed of two
oil-hydraulically operated arms. Because they
are moving out of the way separately, one after
the other, as pressing-stem pushes a billet into
the container, the result is better flexibility.
The loader cradle can be easily adjusted when
changing billet diameters. Ample loading space
is provided between stem and the container, thus
assuring safe and rapid loading.
30
910 MT Press Extrusion Line
BUTT-END HANDLING SYSTEM The butt-end handling
system consists of a chute for directing the
butt- end to the outside of the press, onto a
suitable conveyor. The conveyor throws the
butt-end into a scrap box (of your supply) to be
located on the floor level.
31
910 MT Press Extrusion Line
CONTAINER HEATING SYSTEM The container holder
is designed to permit the symmetrical arrangement
of tubular resistance heaters within the annular
space between the container and the container
holder. The system includes a control board for
automatic temperature control.
32
910 MT Press Extrusion Line
LIMIT SWITCHES Interlocks and press movement
starts and stops are, in most cases, controlled
by limit-switches, though in some cases timer and
pressure switches may be utilized. Where
necessary, adjustable cams are furnished so that
the switches can be actuated. Example to preset
a desired value of butt length, etc..
33
910 MT Press Extrusion Line
MAIN PRESS CONTROL BOARD A press control board
is provided with pushbuttons and selectors to
initiate the various automatic and manual
cycles. The control board contains pressure
gauges and potentiometers for speed control, and
temperature gauges and regulators for the
container. It also has start-and-stop push
buttons for the motors, signal lamps etc It
also incorporates an auxiliary control panel
located on the press near the platen egress
hole. Programmable logic control, electronic
operational facilities, and speed control devices
for press movements (particularly for extrusion)
are located in separate metal cabinets.
34
910 MT Press Extrusion Line
OPERATING CYCLES The presss sequence cycle
control system includes methods for presetting
(and immediate regulation of) the extrusion speed
for any cycle. The oil-hydraulic circuit
includes a slip-compensation system to provide
constantly controlled speed for the main,
regardless of the pressure variance during the
extrusion portion of the stroke. Controlling
the speed of upset, and filling of the die, is
accomplished using pressure-switches and timers,
and can be part of any cycle. The press is
supplied with the following automatic operating
cycles -conventional cycle for open and
porthole dies -normal bridge die cycle -burp
cycle
35
910 MT Press Extrusion Line
HYDRAULIC SYSTEM The main hydraulic system
consists of two pumps of variable delivery, which
allows for stepless volume adjustment. The
entire pumping system (including the main pump)
is mounted over the oil tank, which is in turn
mounted over the main cylinder of press. An
auxiliary, low pressure pump is also provided to
power the cylinders actuating the loading,
handling, and transfer devices. A separate
sealing pump maintains constant sealing pressure
between the container and the die face,
throughout the extrusion stroke. Amply sized
heat exchangers are provided to prevent
overheating of the oil by keeping it below 50C.
Oil filters guarantee adequate oil cleaning.
36
910 MT Press Extrusion Line
OIL TANK The oil tank is mounted over the main
cylinder of the press. The oil tank is of
adequate size and is baffled to prevent foaming
at the maximum press speed. Oil level and oil
temperature gauges will be mounted in such a way
as to be visible from the main operating
pulpit. The entire system is easily accessible
via catwalks and stairways.
37
910 MT Press Extrusion Line
HYDRAULIC PIPING Hydraulic piping is accurately
pre-formed pickled and annealed and pickled
before installation to assure a piping system
free from strains. High pressure piping is of
seamless steel and designed with long gradual
radius bends and with welded flange connections
and O ring seals. Wherever needed, rigid
supports for piping are used. A stop valve is
provided for servicing the pre-fill valve. All
cylinders, valves and piping, where required, can
be serviced without draining of the tank.

910 MT Press Extrusion Line

• Continuous Gas Furnace for Rapid Heating of
  Aluminum Billet with Recuperator
• The furnace consists of a sturdy framework of
  steel beams and welded plates which contain
  insulating material. The heat insulation has
  been obtained by a series of three thermal
  barriers of high insulating capacity. Burnt gas
  is sucked by a centrifugal fan and forced to pass
  through the billet preheating area.
• A billet conveyor is formed using idle rollers
  and cast iron bearing supports designed to work
  in a high temperature environment.
• Temperature control is performed using three
  thermocouples of type K, which get into the
  furnace intermittently via pneumatic cylinders.
  A vertical sliding door, operated by a pneumatic
  cylinder, shuts the unloading area. The heating
  assembly is formed by a set of main burners
  controlled by pilot burners with electric
  lightening, flame detectors, and electronic
  programming panels for combustion control,
  locking valves, pressure switch, and a
  centrifugal electric fan for burnt gas.
  Temperature control is by thermo-regulators PID

M.T. -installed power 30 KW All movements
are automatically actuated and synchronized with
the billet call signal from the press. During
the machine set-up, each operational step may be
accomplished separately from the others via
proper switches and pushbuttons. Billet length
is determined by a motor-reducer which moves the
measuring unit constituted by three photocell
switches. The cutting is performed by the
sliding movement of the movable container head
against the fixed container head. This sliding
movement is accomplished using a hydraulic
cylinder.
52
910 MT Press Extrusion Line
Hot Shear for Billet Cutting (continued)
A set of auxiliary hydraulic cylinders pushes
the log back into the furnace and removes the hot
billet from the cutting area. A shuttle then
transfers the billet onto the press loader. Its
steel frame is of a heavy-duty design, and was
stress relieved before machining. The
containers are made of tempered, forged steel,
and are design for hot working. Different sized
containers can be mounted according to the billet
diameter used. Both containers are divided into
two parts one fixed and the other movable (via
a hydraulic cylinder) in order to have a correct
introduction of the billet, and to assure the
billet is held during the cutting phase. The
movable container slides upon guides made of
bronze. An adjustable, forged steel gib is used
to move the containers. This gib can be used to
provide the exact clearance necessary between the
containers two cutting surfaces. On the shears
fixed part (on the furnace side) a holder and a
cradle have been installed, which permit the
temporary parking of a billet in case of a double
cut.
53
910 MT Press Extrusion Line
Hot Shear for Billet Cutting
(continued) A sensor checks the length of the
remaining billet on the upper part of the cutting
line after each cut. If the length is such that
the next billet will have a crop-end measuring
less than the specified minimum length, the
system will decide to perform a double cut so as
to avoid this. The patented double cut
system guarantees the ability to extrude a whole
billet, without rejects and without crop-ends of
a length smaller than the minimum
specified. With our plant, extrusion rejects
are reduced to a minimum by -eliminating
length standardization problems, -reducing the
need for stocking different diameters and length,
and -eliminating the need to cut with a
circular saw.
54
910 MT Press Extrusion Line
Hot Shear for Billet Cutting (continued)
With our plant, total rejection of the
extrusion process is reduced to a minimum
by -our ability to extrude only the length
desired -our ability to link the hot shear
with the puller via a computer to get an
automatic optimization of the profile and billet
length. -our ability to work with pre-cut
billets, by using a short billet cycle. Hot
shear is supplied with -a hydraulic unit
complete with safety and check valves, filters, a
heat exchanger for oil cooling, and various
fittings, all assembled on a base oil
tank. -the hydraulic unit also includes various
solenoid valves for the control of the
synchronized movements.
