During the task of grinding some bending machine dies, an interesting phenomenon was observed: two companies with roughly similar usage cycles and frequencies had one of them requiring multiple grinding sessions for their bending machine dies. This issue prompted me to ponder over the factors causing this occurrence. I have listed a few possibilities below.
Incorrect usage: Bending machine dies are precision tools with high hardness, strength, and wear resistance. However, incorrect usage can lead to severe wear on the dies. This primarily includes not checking the condition of the bending machine when installing and adjusting the dies. Any abnormalities in the machine can increase friction between the upper and lower dies, leading to significant wear even if the die installation seems fine. Improper die installation can result in the lower die not being perfectly aligned with the bending blade, causing deformation in both upper and lower dies even if the bending angle of the metal sheet seems fine. Deformation at the interface of the upper die connecting plate is another issue that cannot be overlooked after prolonged use. Although not visible to the naked eye, this deformation can have a significant impact on precision dies, potentially causing severe wear on both upper and lower dies.
Solution: For the first scenario, regular checks on the bending machine's condition are crucial as machine status directly affects the lifespan of bending machine dies. If any abnormalities are detected, the dies should be removed, the issues resolved, and only then should the dies be used again. In the second scenario, meticulous care must be taken during die installation, ensuring proper adjustment of the parallel distance between the upper and lower dies before use. In the third scenario, frequent inspections of the connecting plate are necessary. If any angle issues are noticed, attempts should be made to adjust them. If adjustments do not eliminate the deviation, grinding the connecting plate may be required. These factors are closely linked to the lifespan of the dies, emphasizing the need for careful handling when using bending machine dies.
