Press brakes are a great machine but they, too, just like other machines present opportunities for mistakes. But the good thing is the fact that many mistakes are common and having the right prevention tactics will do the trick in solving them. Below are some of these mistakes and avoiding them will help you prevent brake press repair which can be costly.
Common Press Brake Mistakes
This is probably one of the most common mistakes that people make in an average shop. Letting grime and dirt to accumulate can cause excessive wear to gibs and tooling. Dirt can also scratch parts as they form and metal dust that enters the control panel can cause machine breakdown and electrical problems.
As far as press brake technology is concerned, this term is often misunderstood. Press brakes are specifically designed with a deflection limit under full tonnage loading. Given this, deflection is the ram’s tendency to bend upward in the center and the bed to bend downward under full tonnage loading. As soon as the load is removed, the ram and bed return to their normal stability.
This is another serious and common oversight. Every moving part need to be lubricated according to the manufacturer’s recommendations.
Since ram gibs are a critical area, if needed, they should be kept lubricated. There are some machines that have non-lubricated gibways, while others have grease fittings, and some have automatic or manual systems. If the gibs need lubrication, failing to do so can cause them to freeze and become badly worn that will lead to costly brake press repair.
Ram gibs need to be parallel so the ram will not operate with a twisting motion. A ram that is out of level will form imperfect parts and if the angle is bad, the gibs will act as a brake- keeping the ram from going back to the top of stroke without having to increase the return pressure.
Failure to Determine the Needed Bending Load
It is a must to know the required load to make a bend. The load should be based in the type and thickness of the metal, the tooling used, and the length of the bend. By being aware of the bending load, you would be able to distribute the load on the bed, thus avoiding damage to the ram, bed, and tooling.
These ones are the most common mistakes that are often encountered, but still so many people do not seriously. Without realizing it, these ones can actually cause more serious problems when not given attention as soon as possible. These are just a few ones, which means that you need to look out for more mistakes so you can avoid costly repairs and make the most out of your brake press.
