During the use of metal stamping machines, some common faults may occur due to the complexity of the equipment and long-term high-intensity work. The following are common faults of metal stamping machines:
1. The stamping machine cannot start
Power supply problem: power failure or unstable voltage, check the power supply line and fuse.
Control system failure: electrical control part failure, resulting in the inability to transmit the start signal.
Emergency stop button start: The emergency stop button is pressed and must be reset before restarting.
Safety protection device start: If the door is not closed, the pressure is too high, etc., the safety system protection is triggered, check the safety protection device of the equipment.
2. The stamping machine is unstable or abnormal
Pneumatic system failure: insufficient air source, unstable air pressure or damaged pneumatic components, resulting in unsmooth movement.
Hydraulic system failure: insufficient hydraulic oil, damaged or leaking oil pump, resulting in unstable pressure.
Electronic control system failure: electrical control system failure, unable to accurately perform actions.
Mechanical wear: wear of the transmission part causes mechanical jamming.
3. Excessive noise from the stamping machine
Wear or looseness of mechanical parts: looseness or severe wear of gears, bearings, connecting rods and other parts, causing abnormal noise.
Poor lubrication: Insufficient lubricating oil or failure of the lubrication system, resulting in increased friction and noise.
Interference from foreign matter: There are debris or metal chips in the mold or equipment, causing collision or friction between parts.
Failure of pneumatic components: Damage or leakage of components such as cylinders and air pipes may cause increased noise.
4. Oil or air leakage from the stamping machine
Hydraulic system leakage: Aging or damage of components such as hydraulic pumps, oil pipes, and sealing rings, resulting in hydraulic oil leakage.
Pneumatic system leakage: Poor sealing of cylinders, air pipe joints or other pneumatic components, resulting in air leakage.
Aging of seals: Aging and failure of components such as sealing rings and O-rings, resulting in liquid or gas leakage.
5. Excessive vibration of the stamping machine
Unstable foundation: The foundation of the stamping machine is unstable or not firmly installed, resulting in equipment vibration.
Unbalanced mechanical parts: such as gears, shafts, connecting rods and other parts are unbalanced, or severely worn, causing unbalanced vibration.
Uneven load: Improper mold installation and uneven placement of workpieces cause uneven operating load of the stamping machine.
6. Insufficient stamping pressure of the stamping machine
Insufficient air pressure: Insufficient air source or unstable air pressure affects the stamping pressure.
Hydraulic system failure: Insufficient hydraulic oil, oil pump failure, oil pipe leakage, etc., resulting in the stamping machine being unable to provide sufficient pressure.
Wear or damage to the mold: Wear or damage to the mold causes the set stamping pressure to fail to be reached during stamping.
Improper pressure setting: Improper setting of the pressure regulation system causes the pressure to be too low.
7. Unqualified stamping product quality
Mold problem: Mold wear, deformation or improper installation leads to inaccurate dimensions or uneven surface of the stamping product.
Material problem: Raw materials do not meet quality requirements, which may cause deformation, cracking or breakage of the material during the stamping process.
Improper stamping speed: Too fast or too slow stamping speed may cause unstable dimensions or defects in the finished product.
Insufficient pressure: The punching machine fails to provide sufficient pressure, resulting in poor punching effect.
8. The punching machine stops frequently
Overload protection is triggered: When the punching machine is overloaded, the overload protection system automatically stops.
Electrical system failure: The electrical control part fails, causing the equipment to stop.
Safety protection device starts: The safety switch, emergency stop device, door switch, etc. are triggered, causing the equipment to stop.
9. The punching machine is not stable and the punching is uneven
Uneven mold: Wear, deformation or design problems of the mold may cause unevenness during the punching process.
Insufficient pressure: Problems with the hydraulic system or pneumatic system may cause insufficient pressure during the punching process, resulting in uneven products.
Material problems: Uneven quality of metal materials may cause uneven punching effects during the punching process.
Loose or worn mechanical parts: The transmission part of the punching machine is loose and worn, resulting in inconsistent punching actions.
10. Overheating of the punching machine
Insufficient lubrication: Insufficient lubricating oil or failure of the lubrication system causes excessive friction of mechanical parts and generates too much heat.
Motor overload: The motor is overheated due to excessive load or long-term operation.
Cooling system failure: Failure of the cooling water system or coolant system leads to ineffective heat dissipation.
By timely discovering and solving these common faults, the operating efficiency of the metal stamping machines can be improved, the service life of the equipment can be extended, production downtime can be reduced, and production continuity and product quality can be ensured.
