Are you regularly facing errors while bending your metal sheets? As experts in the field, we have compiled a list of common sheet metal bending errors and how to avoid them. Read on to find out more.
The tiniest of errors can result in product damage, dimensional inaccuracy, loss of material, wasted time and effort, and so on. In hazardous situations, the operators' safety may be threatened as well. As a result, it is critical to avoid brake bending errors.
One of the most important parts of the sheet metal bending process is identifying the common errors. Many sheet metal bending issues are caused by operator errors, and the solutions are usually limited to a few preventative measures. To protect your machines and ensure that they have a long life, the operators need to undergo proper training.
1. Issues Related to Bend Radius:
A bend radius that is too tight will result in broken equipment and inaccuracies in the finished product. The bend radius, primarily, depends on the type of sheet metal used and whether longitudinal or transverse bending is performed.
To ensure this doesn’t happen it is advised?
2. Not Cleaning and Lubricating the Machine:
Two of the most common yet overlooked sheet metal bending brakes faults are untidy machinery and insufficient lubrication. Keeping the bending brake setups dirty, traps metal particles, oil, dust, and other contaminants, which can lead to increased jamming between the ram and gibs.
?Furthermore, inadequate lubrication causes friction between the setup's moving elements. Heat is generated as a result of excessive friction, as well as wear and tear.
To reduce jamming and frictional wear and tear, frequent cleaning and lubrication are recommended. Automated or semi-automated lubrication systems can be employed for consistent lubrication.
3. Choosing a Narrow Bending Flange:
Tool overloading occurs when a small bending flange is chosen. This may result in tool damage.
The correct bending flange length must be chosen to avoid tool damage. To choose the proper bending flange length, apply the formula below.
??????Bending flange length= [(4 x stock thickness)+bend radius]
4. An offset Ram:
A ram or bending bed that has been over-offset can result in a temporary or permanent deflection of the machine's center. This results in a bend angle error, which affects every product in the batch, eventually leading to batch rejection.
To prevent this the operator should take the following precautions to avoid upsetting the ram.
