When everyone uses a hydraulic sheet metal bending machine, they definitely hope that it can always maintain a good working condition, but if it fails, we also need to understand the cause of its failure. Common faults include poor surface roughness of the workpiece, taper size of the workpiece, inconsistent workpiece size, and size deviation. In the article, the editor will give you a detailed introduction to the causes of common failures of hydraulic sheet metal bending machines and the precautions for its lubrication.

Reasons for common failures of hydraulic sheet metal bending machines:

1. The surface roughness of the workpiece is poor

The tip of the hydraulic sheet metal bending machine tool is damaged and not sharp; the machine tool resonates and the placement is not stable; or the machine tool has a creeping phenomenon, which leads to poor processing technology.

2. The workpiece produces a taper size head

The placement level of the hydraulic sheet metal bending machine is not adjusted properly, one is high and the other is low, resulting in unstable placement; when turning the long axis, the fed material is relatively hard, and the tool is relatively deep, resulting in the phenomenon of knife yielding; the tailstock thimble and the Spindles are not concentric.

3. The size of the workpiece is inconsistent

The carriage of the hydraulic sheet metal bending machine runs at high speed for a long time, resulting in wear of the lead screw and bearing; the repeated positioning accuracy of the tool holder deviates in long-term use; the carriage can accurately return to the starting point of processing every time, but the size of the workpiece still remains Variety. This phenomenon is generally caused by the main shaft. The high-speed rotation of the main shaft causes serious bearing wear, resulting in changes in machining dimensions.

4. There are deviations in size

The speed of fast positioning is too fast, and the drive and motor cannot respond; after long-term friction loss, the mechanical carriage screw and bearing are too tight and stuck; the tool holder is too loose after changing the tool, and the locking is not tight; the edited program is wrong, the head , the tail does not respond or the tool compensation is not canceled; the electronic gear ratio or step angle of the system is set incorrectly.

Precautions when lubricating hydraulic sheet metal bending machine:

1. All rollers and corresponding components in the hydraulic sheet metal bending machine must be refueled, also three times a week.

2. Add butter to the upper and lower knives, three times a week. Lubricating oil should be added to the clutch section of the lower knife.

3. The sealing coil in the cylinder of the hydraulic sheet metal bending machine should be cleaned and lubricated at the place where the sheet is bent.

4. The refueling of the sliding bearing and the discharge frame of the hydraulic sheet metal bending machine needs to be carried out every three days.

5. When refueling the place of the discharge shaft pressing plate, we use a grease gun to fill the oil, and clean the refueling place before refueling.

6. If you are adding oil to the connection place of the brake, you should move it back and forth after adding oil. Lubricate it three times a week, and pay attention to cleaning.

If you didn't know about the hydraulic sheet metal bending machine just now, then after reading this article, I believe it has helped you to master a lot of knowledge about it!
