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.

Limit Switches
Auxiliary limit switch controls are utilized when not using mechanical depth stops.

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 with material.

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 and ram.

Torsion Bar
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.

Precision Slides
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.

Actuating Controls
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.
