[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This high-precision sheet metal frame bending die, through its locking structure and die structure, allows for die changing operations. By rotating the handle, the threaded rod rotates. Due to the limiting rods on both sides, the threaded rod can drive the locking die to move horizontally, thereby causing the upper two protrusions of the locking die to disengage from the slot. At this point, the module can be rotated 180° so that the second bending opening is directly below the bending die. After positioning, by rotating the handle again, the threaded rod drives the locking die to re-insert into the slot and fix it, thus completing the die changing operation. This achieves the purpose of rapid die changing and improves bending efficiency.
[0015] 2. This high-precision sheet metal frame bending die, through its die structure, allows the sheet metal frame to be placed flat on top of the module during bending. At this time, the extension rod of the push cylinder drives the bending die to move downward. During bending, the sheet metal presses down on the top cover, causing the spring to contract. After the bending die is reset, the spring releases its force and bounces the bent sheet metal frame upward, thereby achieving automatic unloading. Attached Figure Description
