Common problems and solutions for the back gauge of the Press Brake
The Press Brake is one of the most common equipment in the sheet metal processing industry. The back gauge, as the most important auxiliary device of the Press Brake, plays a key role in ensuring the positioning of the workpiece and improving the processing accuracy. In the actual operation process, some common problems may occur due to various reasons. We need to find out the cause of the problem and solve it. This article will summarize several common problems and solutions for you.
1. Abnormal noise occurs during the operation of the back gauge:
(1) The guide rail slider may be stuck and encounter resistance.
(2) The screw nut may be stuck and encounter resistance.
(3) The synchronous belt is seriously worn.
2. The position of the back gauge is offset
(1) The back gauge is displaced by external force.
(2) The screws of the back gauge are loose or fall off.
(3) The impact force of the workpiece is too large, exceeding the bearing capacity of the back gauge.
(4) CNC system failure.
3. The back gauge is unstable and the error is large when it is small.
(1) The screws at the screw nut and the connecting plate are loose.
(2) The fixing screws of the back gauge beam are loose.
(3) Damage to the keyway of the synchronous wheel
(4) Severe wear of the synchronous belt
Solutions to the above problems:
1. Check the back gauge screw regularly and tighten it appropriately.
2. Regularly add lubricating oil to the guide rail slider and the screw nut.
3. When bending the workpiece, the back gauge retreat function can be turned on to avoid impact on the back gauge during the bending process.
4. If it is not a mechanical problem, you need to ask the manufacturer to assist in checking whether there is a problem with the CNC system and repair it in time.
5. Determine according to the frequency of use of the machine. The synchronous belt can be replaced after 2-3 years of use.
