400 Ton Hydraulic Press Machine For Deep Drawing

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

• 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

• 1. Yz27 Series Frame-type Hydraulic Press is a kind of multifunctional precision machine which has high speed.
  2. Optimized design, the frame is entirely welded with steel plates, and treated to relive stress by tempering for high precision.
  3. Cartridge valve equipped for hydraulic control system, reliable, durable and less hydraulic shock, shorter connection pipeline and fewer release points.
  4. Centralized button control system, with adjustment, hand and semi-auto operation modes at operator`s choice (set-stroke single and set pressure single).
  5. Four-angle and eight-side guide rail in high precision and with strong capacity against deflection, concentrated lubrication.
  6. New type of oil cylinder sealing components marked by high reliability and long service life.
  7. Sliding blocks operating in high speed, ensuring high efficiency.
  8. The slide operating pressure, no-load quick travel and low-speed movement can be adjusted according to technological requirements.
  9. 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.
  10. 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.
  11. 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.
