Common mechanical failures and maintenance of press brake machine

Due to its serious load, inadequate lubrication of moving components, and complex operating atmosphere, the press brake machine is incredibly straightforward to cause wear and tear of moving components. Here I will analyze the common mechanical failures and maintenance of press brake machines for everyone. Here are some answers.

Here is the content list:

• When the slider is working, abnormal noises are made.

• The size of the back gauge is inconsistent at both ends (small and large ends).

• No movement of the rear gear shaft and loose connection between the oil cylinder and the slider.

When the slider is working, abnormal noises are made.

This type of failure is due to the long use time of the guide rail of the press brake machine, the guide rail is not lubricated properly, and the gap is increased due to wear. The guide plate needs to be checked for wear and readjusted to achieve the required clearance. According to the degree of wear, determine whether to replace the guide rail pressure plate. If the strain is severe, it needs to be replaced. The original pressure plate was plastered with plastic. Attention should be paid to the choice of sticking plastic hardness and guide rail sticking surface. After scraping, make sure the sticking surface is above 85% and open the serrated lubricating oil box. Inside the original pressing, the plate is a metal plug iron. To choose a tin bronze plate or ductile iron, the fitting surface is processed by a grinder, the connecting bolt should be lower than the fitting surface, and a zigzag lubricating oil groove should be opened.

The size of the back gauge is inconsistent at both ends (small and large ends).

The error at each end is little, within 2mm. Check to confirm that the transmission structure of the press brake machine has no faults. The error can be eliminated by fine-tuning the stop finger. If there's no fault within the transmission structure of the press brake machine take away the fault. Such as bearings, ball screws, linear rails, transmission wheels, transmission belts, etc. Re-adjust to inside the tolerance of similarity, and re-install the synchronous transmission device.

No movement of the rear gear shaft and loose connection between the oil cylinder and the slider.

The failure of the back-gauge shaft transmission of the press brake machine may be because the transmission shaft is separated from the timing belt wheel, the key bar, or the timing belt slips off. Block shaft driver and servo motor failure, upper computer control system failure. Such failures need to check and confirm the cause of the failure, repair or replace the faulty components and eliminate the failure. If the connection between the oil cylinder and the sliding block is loose, it may cause the bending angle to be inaccurate or the press brake machine cannot find the reference point.
