Introducing a maintenance case that addressed the lower limit lever lock issue in RG80s!
We would like to introduce a maintenance case of a press brake that we handled. Two issues occurred: the lower limit lever was not functioning, and the lower limit lock of the table was not working. The lower limit lever had a broken snap ring for preventing the misalignment of the spring mounting pin at the friction plate attachment. Due to wear on the snap ring installation and groove, light welding was performed. The connecting pin was replaced due to damage. After that, operation was confirmed. Additionally, the lower limit lock was not functioning properly because the connecting pin between the handle and shaft was too long, causing interference during rotation and preventing the block from closing completely. The excess length of the connecting pin (cotter pin) was trimmed to eliminate the interference. The lower limit lock was restored to normal operation. [Case Study] ■ Product - Press Brake "RG-80s" ■ Situation - Case 1: The lower limit lever of the table is not functioning - Case 2: The lower limit lock of the table is not functioning (case with RG80s) *For more details, please refer to the PDF document or feel free to contact us.
