JW36 H Frame Double Crank Press

H frame double crank power press (punch press, press machine, punch machine, punch, stamping press, mechanical press), capacity from 110ton to 500ton, welded steel body, PLC control, wet clutch, hydraulic overload protected, auto lubricated, touch screen control. Bigger table better for big sheet stamping and progressive die stamping process. The press can work with NC feeder and transfer system for automatic press line.

H FRAME BODY WITH EIGHT SURFACES SLID GUIDES FOR HIGH PRECISION

JW36 straight side press uses H frame steel welded body which is under heat press precise slide.jpg

treatment and ball ballasting treatment to release the welding stress. The body

is just one time fixed on the CNC milling center table to machining all holes

and surfaces. In this way, the machining precision is much higher than

normal process.

The slide guides are four angles eight surfaces type and the gap can be adjusted

on both front to rear side and left to right side. Precision is already ensured during

machining and just need to fine adjustment when installation or future maintenance.


 



WIDER TABLE BETTER FOR PRORESSIVE DIE STAMPING

JW36 H frame double crank press has a wider table which is more suitable for press big table.jpg

progressive die stamping and big sheet punching process. The upper surface

of press working table is grinded by high performance grinding machine for

better flatness.

Bolster size is customized according to the die size. T slots can be machining

to customer’s drawing or request. Die quick change device is optional and it can

be fitted on the press before shipment if customer orders this QDC system.

Double cross located crankshafts reverse rotated to eliminate each lateral force.

Some customized bigger table press will use three stages transmission through

adding a middle gear. Pneumatic slide balance cylinder is equipped to balance

the slide weight and upper die weight. Press is timing by two big gears which

are oil bath in the top oil house. The two gears timing testing had been done

before installation to the press.

 



BIG TORQUE WET TYPE CLUTCH & BRAKE

Word patented and self-produced wet type pneumatic clutch is standard equippedpress wet clutch.jpg

to all H frame double crank presses while most other manufacturers can only use

dry type clutch. Wet type clutch means all the friction discs and pressure plates

are oil bath in the flywheel house. The oil will act as lubrication and heat radiation

medium. The customers just need to change the oil each half year for future

maintenance. Much lower maintenance cost than dry type. The close type structure

lows down working noise and forbids the dirty inside the flywheel.

Each clutch is under balance testing and temperature testing before assembling to

the press. High quality friction discs ensure long service life. No need to change

them within 3 years. Special high quality Y type seal rings ensure no oil leaking.

 



HYDRAULIC OVERLOAD PROTECTION SYSTEM

The H frame stamping press is standard equipped with a hydraulic overload pump. press overload protection system.png

Normally the press overload protection system is set as 110% of the nominal capacity.

Press will stop immediately once it is overload than 110% to protect both the h

frame press crankshafts and the press die. The system can be reset within 3 minutes.

It is easy to reset the overload as there is a reset switch on the control panel.




 



PLC CONTROL WITH HMI

PLC central control system makes the press easily operation and inspection. HMI has press control panel.jpg

functions of system setting, I/O monitor, counter and preset counter. The operator can

set the lubrication frequency by the HMI according to the working time or working

stroke times.

The press has both mechanical and electrical cam controllers. It is easy to set the cam

angles to match the press with automatic uncoiler straightener feeder system or

transfer bar system.








 



PACKAGE AND SHIPMENT

H frame double crank press size is too big for container shipment. The press frame press package pallet.jpg

is an integrated structure which cannot be disassembled for small package.

Normally the press will be lied down on a strong steel pallet and sides protected by

steel box. The best shipment way is by bulk vessel or flat rack.
