Two both hands operation buttons, scram button, feeder move forward and backward button, the first feeding device feed tank move forward and backward
Button, the second feeding device move forward and backward button, backgauge cylinder of feed tank reset and ejection and is automatically and manually pressed button
Button is additionally provided with origin reset button, as the feeder this dial type button of button that moves forward and backward passes through a button control
Two instructions, be the switch of twisting, corresponding on one side to advance, corresponding on one side to retreat, pushing the position of advance, to represent instruction be to send
Material machine advances, and pushes retracted position and represents feeder retrogressing instruction；And the button of single instruction such as takes blame for others and ejects button, presses
After pressure, ejection of taking blame for others.After opening power supply machine, the power knob on control panel can light, and press punching machine pump switch, to punching
Bed cylinder pressurization, after pressure reaches standard, can be automatically stopped.The present invention have manually and automatically two kinds it is available, work as selection
When automatic work, on the control panel, origin recovery button is clicked, each equipment can be automatically found origin position according to the parameter of setting
It sets, i.e., each equipment finds origin position, and at this moment two hands of worker press a both hands operation button respectively, and equipment will be according to defeated
The parameter entered carries out automated production, since two both hands operation buttons are concatenated, right-hand man is needed to press two pairs together
Hand operation button could start equipment, avoid worker's existing safety when starting button on one side operate machine while
Hidden danger fundamentally prevents the generation of such accident, to greatly improve the safety coefficient of machine operation, while on control panel
Also scram button, it is convenient in emergency circumstances to stop at once；When selecting to be manually operated, automatically and manually hand first will be pushed by button
Then dynamic position then needs to stir each button one by one according to production stage, feeder button is pushed to the position of advance, feeding
Machine begins to advance.Manual operation is opposite to be automatically brought into operation, complex cumbersome and inaccurate, is all used under normal circumstances certainly
Dynamic operation, but when the present invention needs to debug, and needs using individual separate payments, you can selection manual operation, such as individually
Use punching machine.
The present invention gold bar automatic gas cutting machine on the basis of existing digital controlled cutting machine, increase automatic feed device and
Feeding device is truly realized full automatic cutting, after gold bar block is put into feed tank by staff, only need to manually control control
Button on panel, the i.e. controllable modules work of programmable controller, carries out automatic cutting, has saved labour cost, together
When to automatically control contraposition cut quality high, also improve cut quality while promoting working efficiency, greatly improve enterprise
Production efficiency.
