**Common fault causes and solutions for CNC downward bending machines**
1、 The working principle and main components of a CNC downward bending machine
The CNC downward bending machine is an important equipment for metal sheet metal processing. It controls the downward pressure head through the CNC system, and performs high-precision bending of the sheet metal according to the preset bending angle and process parameters. Its main components include CNC system, hydraulic system, mechanical transmission system, mold, etc.
2、 Common Fault Phenomena and Cause Analysis of CNC Downward Bending Machine
1. Fault phenomenon: Inaccurate bending angle
Cause analysis: Possible reasons include mold wear, insufficient hydraulic system pressure, and incorrect parameter settings in the CNC system.
2. Fault phenomenon: The equipment runs unevenly and produces abnormal noises
Cause analysis: It may be caused by loose mechanical components, damaged bearings, poor lubrication, or air mixing in the hydraulic system.
3. Fault phenomenon: Hydraulic system malfunction, such as unstable pressure, leakage, etc
Cause analysis: It may be caused by damage to the oil pump, aging of pipelines, failure of seals, or oil contamination.
4. Fault phenomenon: CNC system malfunction, such as program operation error, display screen malfunction, etc
Cause analysis: It may be caused by damage to internal components of the CNC system, program errors, improper operation, or external interference.
3、 Solutions and suggestions
1. Inaccurate bending angle
Solution: Check the wear of the mold and replace severely worn molds in a timely manner; Check if the hydraulic system pressure is normal, adjust or replace the oil pump; Check if the parameter settings of the CNC system are correct and calibrate according to the operation manual
