Thin-walled parts in the form of cylinders, steps, cones, spheres,
boxes and other irregular shapes can be produced by the drawing
process. In combination with other press forming processes such as
flanging, bulging, flaring, and shrinking, it is also possible to
manufacture parts with extremely complicated shapes. Therefore, in
the production process of industrial sectors such as automobiles,
airplanes, tractors, electrical appliances, instruments,
electronics, etc., the deep drawing process occupies a very
important position.
Yz27 Series Frame-type 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.
Features
1.Hydraulic machine that used the hydrostatic pressure to process
metal, plastic, rubber, wood, powder and other products .
2. It is commonly used in the pressing process and press forming
process, such as: forging, stamping, cold extrusion, straightening,
bending, flanging, sheet metal deep drawing, powder metallurgy,
press-fit etc.
3.Significant technical and economic advantages in reducing weight,
reducing the number of parts and the number of molds, improve the
stiffness and strength, reduce production costs, etc.
