Hydraulic Press Brakes - Types
Santec can provide hydraulic press breaks
for virtually all requirements with several options and additional features.
The various options associated with the press breaks are:
Superior Ram Design
Hydraulic brake presses feature a proven, down-stroking ram system that
results in increased operator control while reducing operator fatigue caused
by up-stroking ram designs. The ram system consists of a thick, rugged ram
that moves between extra heavy side frames. A massive steel torsion shaft is
used to maintain ram parallelism until the mechanical stops are engaged and
lower dead bottom is reached. Mechanical depth stops ensure constant ram
penetration accuracy of +/- .0004. This system eliminates the need for
sophisticated and high-maintenance hydraulic proportional valves, steel
tapes, and micro switches.
Precision Mechanical Depth Stops
Keyed precision mechanical depth stops insure constant ram penetration
accuracy of +/- .0004.
Auxiliary limit switch controls are utilized when not using mechanical
Overload Protection System
Overloading and damage to the press brake and tooling is prevented by a
quick response relief valve system.
Adjustable Stroke and Speed Controls
Stroke length can be adjusted by moving the cam to a position on the slide
that will control the upper most limit of the ram. The ram decelerator
adjustment is automatic, allowing the brake to go into work speed on contact
Adjustable Bearing Block
The adjustable bearing block transmits bed loads to the frame, minimizing
concentrated stresses. These blocks also allow for rapid paralleling of bed
Hydraulic Press Brakes have massive torsion bars which insure parallelism
and three running modes viz. Inching (for setting up tools), singles stroke
(for repetitive work) and continuous stroke (for high production).
Stroke Length Adjustment
Brakes require adjustment only to the top of the stroke. The starting point
of work speed is set automatically when the upper blade contacts the
material. This eliminates time consuming work speed in the air.
Hydraulic Manifold Control Block
All main operating valves are incorporated into one side is a compact
manifold control block. The manifold block permits quick replacement and
adding of more valves for auxiliary functions of NC or CNC Systems. The
possibility of fluid leaks are greatly reduced since interconnecting valve
piping is eliminated.
The ram is accurately guided with minimal clearance in long slide ways
covered with replaceable, anti-friction material. Wear adjustment can be
carried out at any time to insure continued precision.
A three-position foot switch, key selector switch for job, full stroke, and
automatic stroke and dual palm buttons are provided as standard. For precise
control of ram travel, especially for scribed line work, the operator can
switch the press to an "inching" mode that allows jogging the ram
to a scribed line.
