A Complete Analysis Of Common Faults And Repair Methods Of Steel Bar Punching Machines

In the fields of construction and other fields, steel bar punching machines are important processing equipment. However, it is inevitable that some faults will occur after long-term use, affecting work efficiency. Today, let's talk about common faults and repair methods of steel bar punching machines.

Punching accuracy decreases

Fault manifestations

The position deviation of the punched holes is large, and the size does not meet the requirements.

Cause analysis

Mold wear: Long-term use causes wear of the positioning part and punching edge of the mold, affecting the punching accuracy.

Equipment loosening: The bolts and nuts that fix the mold are loose, and the mold moves during the punching process.

Guide rail wear: The guide rails of the equipment are worn after long-term operation, resulting in unstable movement of the slider, affecting the punching accuracy.

Repair method

Replace the mold: For molds with severe wear, replace them with new ones in time to ensure that the mold accuracy meets the requirements.

Tighten loose parts: Regularly check the bolts and nuts of various parts of the equipment, and tighten them in time if they are loose.

Repair or replace the guide rail: If the guide rail is not seriously worn, it can be repaired by grinding or other methods; if it is seriously worn, a new guide rail needs to be replaced.

Insufficient punching force

Fault manifestation

The punch cannot penetrate the steel bar smoothly, or there is a jam during the punching process.

Cause analysis

Hydraulic system failure: Insufficient hydraulic oil, damaged oil pump, blocked oil pipe, etc., will lead to insufficient pressure in the hydraulic system.

Punch wear: After multiple punchings, the punch head is worn, the force area increases during punching, and the unit pressure decreases.

Electrical system problem: The motor speed is not enough and cannot provide enough power.

Repair method

Check the hydraulic system: add hydraulic oil, clean or replace the oil pump, and dredge the oil pipe.

Repair or replace the punch: Repair the worn punch, and replace the new punch if it is severely worn.

Check the electrical system: Check the motor and related circuits to ensure that the motor is operating normally and the speed meets the requirements.

There is abnormal noise when the equipment is running

Fault manifestation

The equipment makes abnormal sounds such as harsh and dull during operation.

Cause Analysis

Loose parts: The fixing bolts of parts such as gears and pulleys are loose, which will cause vibration and noise during operation.

Poor lubrication: The moving parts of the equipment lack lubrication, resulting in increased friction and noise.

Damaged bearings: The bearings are worn and fatigued after long-term use, and abnormal noise will be emitted during operation.

Repair methods

Tighten parts: Check and tighten the bolts of loose parts.

Add lubricant: Add appropriate lubricant to each moving part regularly according to the requirements of the equipment.

Replace bearings: If the bearing is damaged, replace it with a new one in time.

Understanding the common faults and repair methods of steel bar punching machines can help us quickly troubleshoot and solve problems when equipment problems occur, ensuring smooth construction. I hope this article can help you.
