What Are the Common Failures of Pneumatic Punch Presses?

There are more kinds of pneumatic punching machine brands. For national standard punching machine, if there is a fault problem, it is still better to deal with it, because its manufacturing parts and so on are standard parts, good to buy and easy to repair.

If the pneumatic punch press runs abnormally, the feeding should be stopped.

In the operation process of pneumatic punching machine, the operator should not be too careless and should always pay attention to its working condition. If the operator finds any abnormal sound or operation of the precision punching machine, he should stop feeding immediately and check the cause of the abnormality at the first time.

For example, when it has bursting sound or combination sound, make sure to stop the feeding process first.

After inspection, if it belongs to lose die of pneumatic punching machine, malfunction of control system, or loose or defective rotating parts, the operation of punching machine should be stopped immediately for inspection and repair.

In case of abnormal operation of the punch press, the feeding should be stopped and the inspection and repair should be carried out at the initial site so that the punch press can be restored to normal condition at a faster rate.

Every piece of equipment needs regular maintenance, and so does the maintenance of each system of a pneumatic punch press.

How to maintain its various systems? Let‘s first look at how to maintain the lubrication system of a punch press, such as checking how its oil supply looks like, on-site inspection of oil contamination; whether the oil pipe is leaking; and whether the automatic lubricating oil refill is adequate.

In order to maintain the electrical system of the punch press, make sure to check whether the power supply is out of phase and grounded, operate the switch, repair and clean the electrical cabinet, whether the solenoid valve and motor have abnormal sound, cam switch and micro switch (stop using at fixed point), and whether the counter count is standard.

The maintenance of the systems of pneumatic press also includes the mechanical drive system, such as checking whether its screws are loose; checking the tension of the main motor v-belt; clutch, slider and brake shafts, springs and gears are damaged or broken.

Customers in use, do not want to have problems with the machine, but with the increase in the number of years of use, more or less some parts aging, or other failures, the following are a few common failures collated by the company.

1, Clutch failure: clutch brake pad wear, joint leakage, solenoid valve does not work, etc.
2, Connecting rod failure: pneumatic press slide punch cannot be adjusted up and down, connecting rod rupture, screw cannot rotate, connecting rod jumping a lot, connecting rod wear.
3, High-pressure oil chamber failure: oil leakage, not playing oil, playing non-stop, punching non-stop materials, etc. Crankshaft failure: crankshaft fracture, crankshaft runout is too large, the machine heats up, overload mechanism damage, cannot adjust the mold, comprehensive gap, solenoid valve abnormal, balance cylinder leakage, machine precision is not enough, clamping device abnormal, oil circuit blockage, motor cannot start, etc.
4, Parts damage: pneumatic punching machine in the work process, the slider has been in high-speed reciprocating motion, so the machine has been in a state of vibration. In the process of long-term continuous work, parts under the action of vibration stress, the probability of failure is higher.
