CXP hydraulic presses
|
Hydraulic
presses for extrusion of non-ferrous metals (aluminium and copper
alloys) in both direct and indirect extrusion process are designed
in type line CXP for producing bars, sections and wires (whole pipes
and hollow section bars can be produced of suitable alloys and by
using special tools only)
Hydraulic presses of type CXP are of a robust horizontal design. They
are equipped with moving containers and piercing devices (with the
CXT presses only). The prestressed columns of the press build up,
together with the cylinder crosshead and the platen, a rigid press
frame. The presses are designed with all the equipment necessary for
full mechanization and automation of the operation cycle. The moving
container is heated by electric heaters and its temperature is controlled
automatically.
Remote control of the press operation is designed with a hydraulic-electrical
system combined with electronic circuits which are actuated from a
control pulpit by means of pushbuttons and other controls. The control
system is connected to a control computer which facilitates full automation
of the press operation cycle. |
|
The machines are driven directly by high-pressure
oil pumps installed in proximity of the press. The drive of low-pressure
circuits is arranged above the cylinder crosshead.
Rigid design of the presses based on well proved
construction groups, reliable hydraulic, electrical and electronic
control elements are decisive for:
- an integral solution of the production
process
- good surface quality and dimension accuracy
of extruded products
- safe operation and reliable function
- reduction of auxiliary time values
- reduction of power consumption and operation
staff number
- the application of computer assuring automated
operation cycle contro
