1250 Ton H Frame Hydraulic Press Sheet Metal Stamping Press High
Performance Servo System Hydraulic Press
The hydraulic press is suitable for the pressing process of plastic
materials. Such as powder product molding, plastic product molding,
cold (hot) extrusion metal forming, sheet stretching and
cross-pressure, bending, turning, correction and other processes.
The H Frame hydraulic press can be divided into H Frame hydraulic
press, four-column three-beam hydraulic press, and four-column
four-beam hydraulic press.
Compact block eliminates the possibility of leakage and reduces
hydraulic piping. This low noise hydraulic system is located
between the two side plates at the rear of the machine. The
hydraulic system is driven by a reputable electric motor and is
connected with a pump that generates more pressure than necessary.
Pressure gauges of system pressure, back pressure, holding pressure
are located at the top of the oil tank, and quick reference is
possible. Die Spotting Hydraulic Press
A hydraulic press is a machine that uses liquid as a working medium
to transfer energy to achieve various processes. In addition to
forging forming, hydraulic presses can also be used for correction,
press fitting, packing, briquetting and pressing. The hydraulic
press includes a hydraulic press and a hydraulic press. A
water-based liquid is used as a working medium, which is called a
hydraulic press, and an oil as a working medium is called a
hydraulic press. The specifications of hydraulic presses are
generally expressed in terms of nominal working force (kilograms)
or nominal tonnage (tons).
Yz27 Series H Frame Hydraulic Press is a kind of multifunctional
precision machine which has high speed.
Optimized design, the frame is entirely welded with steel plates,
and treated to relive stress by tempering for high precision.
Cartridge valve equipped for hydraulic control system, reliable,
durable and less hydraulic shock, shorter connection pipeline and
fewer release points.
Centralized button control system, with adjustment, hand and
semi-auto operation modes at operator`s choice (set-stroke single
and set pressure single).
Four-angle and eight-side guide rail in high precision and with
strong capacity against deflection, concentrated lubrication.
New type of oil cylinder sealing components marked by high
reliability and long service life.
Sliding blocks operating in high speed, ensuring high efficiency.
The slide operating pressure, no-load quick travel and low-speed
movement can be adjusted according to technological requirements.
Hydraulic cushion is fitted beneath the worktable; adequate
knockout hole and hydraulic cushion are prepared on the plate of
worktable with the operating modes including drawing, ejection and
no ejection.
The working speed of this equipment is 3 to 4 times faster than
that of Y41. It employs eight-side guide device and ejecting
device, which can automatically eject workpieces with accurate
guiding and fast speed.
The drawing device can be added to this equipment in order to
change moulds easily. But the stretching of large metal parts needs
to add hydraulic cushion to this equipment.
