Kallesoe Machinery A/S' electro-hydraulic frame press R20h is a sturdy and strong press, whose change-over to new measures is done by gear motors. The frame press leans backwards 10°, giving a comfortable weight distribution when taking out pressed frames. The standard version of the press is equipped with 3 vertical and 2 horizontal pressing sections. The stroke of the hydraulic cylinders is 150mm. All beams are planed and surface ground, and brass or cast iron is fitted onto all sliding surfaces. 

Adjusting of the cylinders and retainers is done synchronously by means of spindles with right- and left-hand thread towards the center of the machine, ensuring a comfortable working level for all frame sizes. The adjustment is done quickly and silently by means of vide-angle cardan shafts driven by the same gear motor. This system ensures that the angles are adjusted correctly at any frame sizes. 

The width setting is done from the right hand side to the fixed retainer at the left hand side. The retainers and the vertical beam at the left hand side are adjustable to achieve right angles. A pneumatic cylinder secures the beam with the horizontal pressing cylinders to two horizontal tooth bars, safely and precisely. 

The hydraulic system is strongly built with a sturdy pumping station yielding a pressure of 1800kp/cylinder at 160 bar. The pumping station is equipped with an accumulator tank ensuring an even pressure. 

The pressure can be adjusted separately for each set of pressing cylinders

  *Min. 350mm when equipped with special spacers.

Kallesoe Machinery A/S' hydraulic frame presses R16h and R17h are sturdy and strong presses equipped with 3 vertical and 2 horizontal pressing sections in the standard edition. The hydraulic cylinders have a stroke of 100mm and yield a pressure of 1050kp at 110 bar. 

All pressing beams, beds, retainers and pressing shoes are planed and surface ground. All pressing beams are suspended on easy rolling ball bearings and the upper cylinder brackets are fitted with counterweights to ensure an easy and quick adjusting to new pressing measures. The retainers at the bottom of the pressing beams can be locked in 4 different positions to ensure a comfortable working level for all frame sizes. 

The hydraulic system is strongly built and fitted with a reliable pumping station. The pressure for vertical and horizontal pressing cylinders can be set separately by means of pressure sensitive switches. The operating valves for the cylinders are equipped with sliding bars in the full press length. The operating handles will then always be at hand, no matter where the operator is. 

Extra equipment
The frame press can be delivered with extra pressing sections, other pressing measures and a different pressure if needed.
It is also possible to deliver the press with a tilting device making the assembly of large and heavy frames easier.
The controls can be improved with an automatic pressing cycle which can be activated by the operator by means of a pedal. 

This efficient and sturdy frame press is manufactured in 2 sizes and is fitted with 3 vertical and 2 horizontal pressing sections.  

All beds, retainers and pressing shoes are planed and surface ground. The pressure beams are easily adjusted because suspended and running on ball bearings. They are quickly loosened and fixed by means of handles and eccentrics. To achieve exact angles, the lower pressure shoes are fitted with threads allowing a quickly fine adjustment and final fixing with setscrews. 
Furthermore the press is fitted with filter and lubricator.

Both types of frame presses can be fitted with extra pressing beams with cylinders for horizontal and vertical pressing. And they can be fitted with tandem cylinders doubling the pressure. 

Extra retainers to achieve a more convenient working level when pressing small frames can also be delivered.

This frame press is specially designed to press window and door frames. It is equipped with an electric setting of the pressure measures by means of spindles and motors.
The vertical pressure is activated by three servo motors and the horizontal by a through-going bearer driven by a servo motor. These are located to the left and press to the right.
The frame press is equipped with two positioning plates to control the vertical post (middle post). Pressure in and out is controlled by a program.
Two pneumatic cylinders maintain the side members (top, bottom) and the vertical post (middle post) in a horizontal right angle.
A light barrier in front of the press ensures a safe automatic setting of pressure dimensions. All manual operation of the equipment is done by means of a control board with touch panel.
