UNMATCHED FORMING
EFFICIENCIES FROM TWO MODELS
Whether your press brake needs are for air
bending or bottoming, high volume or regular
production runs, MTH II press b~akes
offer improved production levels from two models.
Compare our operating speeds and features
against "other" press brakes and see why Wysong
is your smartest press brake investment for fast
return and long term operating efficiency.

A SIMPLE HYDRAULICS PACKAGE
PROVIDES LOW MAINTENANCE
AND HIGH PRODUCTION
OPERATION
The simple, uncluttered, hydraulics package
incorporates all the valving in a single hydraulic
manifold. The monoblock manifold design reduceS
the amount of tubing and connections to ensure
ease of maintenance, if ever reqUired. The aircraft
quality steel tubing is flared, fitted, neatly
arranged, and connected for a lifetime of
hydraulic integrity.
Because the speed of the ram is gravity
assisted in approach. higher operating speeds are
obtainable with lower power levels, and
with less oil volume. With less oil requirement, the
oil reservoir is designed substantially narrower to
permit the forming of long parts with, acute
angles, above the height of the machine .
HEAVY, MONOBLOCK
HYDRAULIC CYLINDERS
The cylinders are monoblock construction
and are machined from blocks of forged 1141 steel.
The bore in the cylinders is honed to a
16 micro-inch finish. The monoblock design re­
duces seal interfaces. wear points and load concen­
tration.
The monoblock cylinder provides far superior
strength and sealing characteristics compared to
the traditional tube and end cap design.
The pistons are precision finished. induction
hardened. and are fitted with high quality. pressure
sensitive seals. The piston rods are accurately
gUided through the stroke by multiple nonmetallic
bearings.
The heavy cylinder mounting plates are
machined with a shoulder to provide positive
location for the cylinders. This ensures that the
mounting bolts are never in a shear condition when
the machine is under load. The design also
transfers the forming load to the frames and pro­
vides a large bearing surface. The mounting plate
weldments are engineered to withstand a shear load
equal to six times the maximum tonnage rating of
the press brake.
Highly reliable
PLC simulates
relay logic and
reduces the
amount of
electrical
circuitry to
ensure easier,
faster servicing
and trouble
shooting.
~.
FOUR POINT, RAM GUIDING SYSTEM
To ensure positive lateral and vertical stability of
the ram as it travels through the stroke. Wysong
uses four widely spaced. nonmetallic ram gUides
and two precision roller gUides.
When the machine is under load. the work force
is distributed to four points rather than two. The
four point gUiding system eliminates excessive wear
to the gibs when forming large sheets of plate
that produce rear loading on the ram.
True center line loading is achieved through this
reliable gUiding system and the spherical connector
interface between the ram and piston rods.
t,
\)
RAM BRACE FOR STRAIGHTNESS
An adjustable brace is mounted to the back of
the ram to provide a straightness of±.001" per foot
along the length of the ram.
HEAVY TORQUE TUBE DESIGN
The large torque tube stabilizes both ends of the
ram to ensure ram parallelism during operation.
An eccentric on one end of the torque tube
assembly allows for easy adjustment of ram tilt
to compensate for worn tooling. or to permit
fade-out bending
For improved setup and
material handling. MTH
II press brakes can be
easily integrated to
the more popular CNC
gauging systems
available.
The press brake shown is
equipped with a Hurco
two axis back gauge.

The easy access stroke control unit provides
qUick ram adjustment of stroke length, speed
change point and ram bottom stop position. The
stroke length and speed change point are adjusted
by qUick adjusting cams, while the bottom stop is
positioned by a handwheel attached to a precision
lead screw.
• TOP STOP - or stroke length is qUickly adjusted
by moving the Top Stop indicator up or down .
For a smaller shut height, for more strokes per
minute. the indicator is positioned further
up the scale .
• SPEED CHANGE - is adjusted to where the
operator wants the approach speed to shift to
press speed to avoid sheet whip-up. By moving
the indicator up, the speed change occurs closer
to the work.
• BOnOM STOP - is a fine adjustment for accu­
rately controlling the lower limit of ram travel.
The Bottom Stop handwheel adjusts the ram to
control the upper die penetration for air bending
work. When performing bottoming operations,
the upper die is easily positioned to compensate
for the material thickness to be formed.
TONNAGE CONTROL
MTH II press brakes are furnished with a manual
tonnage control that allows easy adjustment of the
tonnage to suit the material to be formed.
After you have determined the tonnage required
for the material to be formed, you simply dial in the
appropriate tonnage with the control knob.
Easy adjustable tonnage increases the life of the
tooling and machine by allowing the operator to
adjust the pressure to meet individual
job requirements.
LOW SPEED CONTROL
To assist in the repeatability of the ram,
especially when forming light gauge material, the
low speed control slows the ram speed to ensure
better than ±.002" ram repeatability for air bending
operations.
RAM TILT ADJUSTMENT
Easy ram tilt adjustment is provided to
compensate for worn tools, material variations
and operations reqUiring fade-out. The ram can be
tilted up to 1/4".
FLUSH FLOOR BED DESIGN
Flush floor bed design is available on all models
from 60 tons to 400 tons, up to fourteen feet bend­
ing capacity. The flush floor design eliminates the
high cost of constructing a pit to accommodate
below-the-floor, bed designed press brakes.
STANDARD CONSTRUCTION FEATURES
