160ton To 600ton Straight Side H Frame Eccentric Press Machine
BENEFITS & FEATURES
Main features of eccentric press machine
. Single crank with con-rod and pneumatic clutch with flywheel
. PLC control with HMI
. Steel welded mono-block type body
. High reliability and precision with 8 faces slide guides
H FRAME BODY WITH HIGH RIGIDITY
JW31 straight side press uses a strong H frame body. The press body is steel welded
with high quality steel plates by carbon dioxide arc welding. After welding, all the
weld seams must pass the examination of ultrasonic inspection. The top transmission
gearbox is tested by oil bath to avoid any oil leak. Then, the press body will be heat
treatment and sand blasting. All these treatments will help to release the welding
stress for high rigidity. Press structure is optimized by computer and all the key
power points are strengthened.
HIGH PRECISION BETTER FOR BLANKING AND CUTTING
JW31 H frame single crank press uses 8 surfaces type lengthened slide guides with
bronze plates for higher guide precision. This type press is more suitable for blanking
and cutting process such as hinges production.
Press working table surface is grinded by high performance grinding machine for
better flatness.
Motorized ram adjustment precision is just 0.1mm with a digital indicator.
Press cross located crankshaft is under roller pressing treatment for better roughness.
The material is forged 40Cr with high hardness.
Transmission gears are grinding, high precision and lower noise.
PATENTED WET TYPE PNEUMATIC CLUTCH
Press with pneumatic clutch can work as continuous, inches or single stroke, more
choices for operators. And a wet clutch is much better than dry type for lower noise
and lower maintenance cost. All the parts are closed inside the flywheel for dirty proof
and low down noise. Just need to change the oil every half year, no need often to
change the friction discs.
The friction discs and pressure plates are oil bath in the flywheel. Oils give better
lubrication and heat radiation which ensures longer service life.
Brake system can stop the press at any point especially for emergency stop.
The clutch uses high quality friction discs and seals. Special Y type seals ensure no oil leak.
All clutches are under balance testing and temperature testing before assembling to the press.
OPERAITON AND MAINTENANCE
JW31 press is PLC control with HMI and cam controller. The press has both mechanica
l and electrical cam controllers. It is easy to set the cam angles to match the press with
automatic NC feeders or press transfer system. HMI has the function as with system
setting, lubrication setting, I/O monitor, counter setting and TDC reset.
Auto grease pump is standard equipped on the press and the operator can set the
lubrication frequency by the HMI according to the working time or working stroke times.
Operator only needs to check whether enough grease in the cup every working day.
Press ram is adjusted by brake motor with a digital shut height indicator. Precision is 0.1mm.
There is a button and an up/down selection switch on the control panel. So easy to test the
die height when install the die or change the die.
SAFETY
JW31 straight side power press is standard equipped with hydraulic overload system.
Normally the system is set as 110% of the nominal capacity. The press will stop immediately
once it is overload than 110% to protect both the press and the die. It is easy to reset the
overload as there is a reset switch on the control panel. The system can be reset within
3 minutes.
Anti-repeat system is equipped to protect the operator when the press works as single
stroke mode. Emergency stop button is on the control panel to stop the press ram
immediately if any dangerous happens.
Double-hand control buttons give another safety system as the operator must press both
buttons at same time to avoid putting hands into the working area. Light barriers are optional
to protect the operator hands when press is working. An emergency stop button on the panel
can stop the press immediately once press the button down.
