Double Crank Straight Side Stamping Press

H FRAME BODY WITH EIGHT SURFACES SLID GUIDES FOR HIGH PRECISION
The straight side press uses H frame steel welded body which is under heat 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
H frame double crank press has a wider table which is more suitable for 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.
Quick die 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/DRY TYPE CLUTCH & BRAKE
Our patented and self-produced wet type pneumatic clutch is standard equipped 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.
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 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.
