What matters should be paid attention to in the installation and debugging of automatic stamping production line equipment?

Here is a list of matters needing attention for installation and debugging of an automatic stamping production line that is practical, wordless and directly usable on site, covering a full set of key points such as punching machine, feeder, manipulator, mold and safety:

Matters needing attention in installation and debugging of automatic stamping production line

I. Foundation and Installation Positioning

The ground must be firm and flat with sufficient bearing capacity to avoid sinking and vibration of the equipment.

The center lines of punch, feeder, manipulator and conveyor belt must be aligned, and too large deviation of coaxiality will lead to feeding deviation, die collision and abnormal sound.

All equipment must be leveled, and the anchor bolts should be locked to prevent displacement during work.

Sufficient safe operation space and maintenance space shall be reserved to avoid interference.

Second, the electrical and gas installation

Connect in strict accordance with the wiring diagram, the three-phase phase sequence is correct and the grounding is reliable.

The gas path pressure is stable at 0.5 ~ 0.7 MPa, and there is no air leakage or water accumulation.

The signal wire and the power wire are routed separately to avoid misoperation caused by interference.

All emergency stop buttons, emergency doors and gratings must have independent circuits and reliable actions.

Three, mechanical linkage and synchronous debugging

The signal linkage between feeder, manipulator and punch must be accurate: relaxation signal, top dead center signal, start signal and interlock signal.

Action sequence must be reasonable:

The slide block of the punching machine goes up → feeding/fetching → the slide block goes down.

Time sequence disorder is strictly prohibited, otherwise it will bump the mold, press the material and damage the equipment.

Speed matching: the feeding speed and manipulator speed are synchronized with the stroke of the punch, and there is no rush or lag.

Four, feeding and leveling system (key)

The clearance and pressure of leveling wheel should be adjusted according to the plate thickness, and the pressure of thick plate should be sufficient to prevent unevenness.

The pressure of the feeding wheel is moderate, and the material will not slip or be excessively crushed.

The tension of the coil is moderate, and it is not loose or wrinkled to prevent the unstable feeding length.

During the trial punching, the step distance is measured many times to ensure the stable feeding accuracy.

V. Mould and Interference Inspection

Turn the car manually before debugging, and check whether the mold, manipulator and feeder interfere with each other.

Adjust the closing height and stroke of the mold properly to avoid traffic jam and overload.

The ejector and stripper mechanism is smooth, preventing material from being stuck and carried.

Six, safety matters (top priority)

All safety devices must be effective: grating, safety door, two-hand button, emergency stop and safety interlock.

During debugging, inching must be given priority, and direct automatic high-speed operation is prohibited.

It is forbidden to put your body into the dangerous area, and it is forbidden to be operated and monitored by special personnel.

Stop the abnormal situation immediately, and then check it after power failure.

Seven, commissioning and running-in

Test the machine with no load first, and check the abnormal sound, vibration and temperature rise.

Then test the material at a low speed and gradually increase the speed.

Run continuously for a period of time, and check whether the temperature of motor, bearing, cylinder and guide rail is normal.

Fill lubricating oil and butter as required to ensure proper lubrication.

VIII. Prevention of Common Problems

Incorrect feeding: check the synchronization signal, belt and roller pressure.

Deviation: the center is not aligned, and the left and right pressures are uneven.

Die collision: wrong timing, unchecked interference, and too fast speed.

Abnormal vibration: poor level, loose foundation and insufficient lubrication.

Nine, ending

Record debugging parameters and back up the program.

Clean up the site, fix the pipeline and mark it.

Conduct simple training for operators, and confirm that they will stop in case of emergency.
