400 Ton Hydraulic Press Machine For Deep Drawing For Automobile
Industry Deep Drawing Hydraulic Press
Deep drawing is a stamping processing method in which a flat blank
is pressed into a hollow workpiece of various openings by using a
drawing die, or a hollow hollow member which has been formed into a
hollow member of other shapes, and the drawing is also called
drawing. The deformation process is: as the punch continues to
descend, the outer diameter of the blank remaining on the end face
of the die is continuously reduced, and the circular blank is
gradually pulled into the gap between the convex and the concave
die to form a straight wall, and is under the punch. The material
becomes the bottom of the deep drawing piece. When the sheet
material enters the gap between the convex and concave molds, the
drawing process ends, and the flat blank becomes a cup having a
certain diameter and height. Compared with the blanking die, the
working part of the deep drawing and the concave die should not
have a sharp cutting edge, but have a certain rounded corner, and
the single side gap between the convex and concave die is slightly
larger than the material thickness.
Rotary body parts such as cylindrical, stepped, spherical, conical,
parabolic, etc. can be obtained by drawing process
Application
- Automobile industry: vehicle body cover, door, automobile hub, battery cover, chasis,
fule tank. Can be also used for other vehicles like tractor,
motorcycle, wheelbarrow.
- Electric products industry: refrigerator, air condition, microwave oven, washing machine and
more.
- Kitchen ware industry: kitchen sink, metal cookware, LPG cylinder

Key Features
- 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.

Safety Device
1) emergency stop button: press the "emergency stop" button, the
hydraulic system, including the motor, will stop running. The press
is equipped with two emergency stop buttons, one on the operation
control panel and the other on the mobile operation table. In any
state and situation, press any one of the emergency stop buttons,
and the press stops immediately.
2) Two-handed operation button: Press the synchronization time with
both hands within 0.5S, if it exceeds, it will be invalid.
3) Hydraulic Support Safety Circuit: In order to prevent the slider
from going out of control, a hydraulic double-support safety valve
circuit is installed in the lower chamber of the piston main
cylinder to ensure safety. The hydraulic interlocking circuit is
set to ensure that the upper chamber of the main cylinder can not
be pressurized when the supporting safety valve is not opened.
4) The machine is equipped with power supply, work and other
indicators.
5) Longitudinal adjustable safety grating protection device is
installed on the front of the press with adjustable position and
600 mm protection height.
6) Overload protection: The hydraulic system is equipped with a
safety valve, which automatically overflows and discharges oil when
the oil pressure exceeds the set value (adjustable), and sends an
alarm signal at the control box.
7) Electrical system protection, motor overload protection and
short-circuit protection, control circuit short-circuit protection
and system alarm function.
8) Touch screen displays all solenoid valves and travel switches
for monitoring.
