The machine is mainly composed of: hydraulic system, electrical
control system, pressure plate balancing mechanism, pressure plate
and body composition.
(1), hydraulic system: from the fuel tank, fuel tank, oil pump,
pump motor, control valve block and pressure gauge composition. The
tank is filled with oil and the oil pump is driven by the pump
motor to pump the oil. The oil is sent to the cylinder by
connecting the tubing to allow the cylinder to work. Wherein the
relief valve controls the maximum pressure of the hydraulic system
and acts as a safety valve to prevent the passage from passing
through; the one-way throttle valve can cause the back pressure to
produce the back pressure during the pressing process, and the
electromagnetic ball valve is used to hold System pressure,
pressure gauge to show the pressure size.
(2), electrical control system: mainly by the main circuit and
control circuit, the circuit using automatic circuit breakers,
fuses, AC contactor on the machine motor, solenoid valve, such as
overload, short circuit, loss of pressure and undervoltage
(3) pressure plate balance mechanism: mainly by the balance lifting
rack, lifting gear, rotating shaft, fixed rotating bearing
composition. About two balanced rack mounted on the fuselage,
rotating shaft fixed at both ends of the lifting gear, both ends of
the rotating shaft bearing, so that the rotation axis can be
flexible rotation. When the lifting plate is lifted, the lifting
gear does not balance the meshing rotation of the rack, so that the
pressure plate always keeps the balance during the lifting process.
(4), the pressure plate: the upper plate and the pressure plate
composition. The upper and lower press plates are made of welded
profiles and steel plates. The working plane is machined by a large
gantry milling machine to ensure smooth and smooth working plane.
The upper pressure plate is connected with the cylinder rod of the
cylinder, and the lifting and lowering of the pressure plate is
realized by the lifting and lowering of the cylinder. Under
pressure plate directly welded to the fuselage base. Making the
whole structure fastened.
