The ram plate is:
- designed in a strong solid steel block
- equipped with T-slots for tool clamping
- machined according to DIN 650
- guided by 4 hard chromed steel columns, and 4 bronze bushings
Allowable off-centre load of 3% of max. press force.
Production Presses
Custom built C-frame single-column press with press force from 25 ton to 300 ton.
Our quality C-Frame Press offers an open and flexible working area and can easily handle a variety of materials, sizes and shapes for even the toughest metal-forming and assembly applications.
With high cylinder accuracy and great versatility, the press guarantees constant performance on a wide range of industries, materials and applications such as bending, punching, forming, straightening, cutting and assembling.
The modular STENHOJ C-Frame Production Press is designed with two optional guiding systems and two optional programmable control systems.
2 and 4 Guided columns
25-300 Ton Pressing Force
Die Cushion up to 150 ton pressing force
Flexible location of power pack
Freely programmable control panel
Modular Design
Prepared for automation
Stenhøj designed cylinder with extra long guides
Regenerative hydraulics:
Unloaded maximum speed: 0-140 mm/s
Return: 0-140 mm/s
Pressing speed at 30% load: 0-50 mm/s
100% load: 0-20 mm/s
The hydraulic power pack is located at the rear of the press and is easily accessible and service friendly.
All our pump systems are designed to fit each press size to achieve low energy consumption and avoid excessive heat in the hydraulic system.
Our power packs are equipped with a hydraulic pump for each cylinder axis. This ensures that the Main axis, Die cushion and Ejector can work independently at the same time.
To reduce unnecessary heat and energy consumption we operate with axial pumps which match the flow to the desired speed and are designed to avoid overload of the motor and clutch system by reducing the flow automatically when the press force increases and approaches max power.
The pumps are submerged directly into the oil tank, which provides low noise.
The valve system on the hydraulic tank is made up of compact block units protected against overload, placed on the hydraulic tank and designed as a hydraulic safety system in compliance with European safety requirements.
Electric motors are minimum IE3 premium efficiency rated.
We design all our cylinders in-house.
Exact guiding and good seal components are important for press cylinders.
Over the years, Stenhøj has developed and standardised our cylinders with long guides, to obtain an accurate and strong piston guide.
For this purpose, we use high quality, expertly processed steel pipes with a cylinder surface which are either roller polished or honed for achieving a smooth and durable surface, together with a grinded and hard chromed piston rod.
The guide bushes are made of our special material that provides a strong and precise guide along with our reliable wear-resistant and tight sealing elements guarantee the cylinders a long service life.
The well dimensioned Bed- and Ram plate is equipped with T-slots for clamping and support of the press tool.
We offer customised Bed plates and Ram plates dimensions with desired holes and T-slots
Ram plate guiding specifications
The Ram plate is guided by 2 or 4 columns through guides with self-lubricating bronze bushings from above. In order to ensure a stabilised construction, the columns are integrated into the Ram/slide plate.
