Abstract
The invention discloses a production line and a process for punching a U-shaped beam. The production line for punching a U-shaped beam comprises a feeding mechanism, a workpiece feeding device, a punching main machine for punching the ventral side of the U-shaped beam, a blanking feeding device and a blanking device, wherein a wing-surface punching machine for punching and marking the wing surfaces of the U-shaped beam is arranged at one side of the punching main machine. The process for punching a U-shaped beam comprises the following steps of: (1) placing the U-shaped beam on the workpiece feeding device; (2) conveying the U-shaped beam in the punching main machine and punching the ventral side; (3) enabling the U-shaped beam to enter the wing-surface punching machine from the punching main machine and marking at corresponding positions of the wing surfaces of the U-shaped beam; and (4) conveying the U-shaped beam to the next working procedure by the blanking device. The invention has the advantages that the subsequent working procedures are simplified, the production efficiency is improved, and the production cost is decreased because the hole positions of the left wing surface and the right wing surface of the U-shaped beam are punched and marked before or after the ventral side is punched so as to avoid repositioning hole positions in the next working procedure.
