[0006] As a preferred solution, the upper die mounting plate is provided with a pair of floating guide rods to guide the upper die floating pressing block, and the lower die base is provided with guide holes that match the floating guide rods.

[0007] As a preferred solution, the upper forming block is provided with a pair of positioning pins that match the positioning holes on the workpiece, and the lower die forming block is provided with positioning avoidance holes that avoid the positioning pins.

[0008] As a preferred solution, a pair of mold closing guide columns are provided on the upper mold mounting plate, and a mold closing guide seat that cooperates with the guide columns is provided on the lower mold base.

[0009] As a preferred solution, a plurality of elastic pressing pins are provided in the upper forming block.

[0010] As a preferred solution, the lower forming block is provided with a pair of elastic pins for lifting the workpiece.

[0011] The beneficial effects of the utility model are as follows: the stamping die adds four movable edge forming blocks around the part, and the driving block drives the side forming blocks to perform flanging, thereby ensuring the verticality of the straight wall surface of the flanging; thereby, a set of dies can be used to complete the two processes of punching and flanging, reducing the number of processing steps and the number of dies, reducing the die manufacturing cost, and improving production efficiency.

[0012] Since the upper die mounting plate guides the upper die floating pressing block via a pair of floating guide rods, and the lower die seat is provided with guide holes that match the floating guide rods, the movement of the upper die floating block is more stable.

[0013] Since the upper forming block is provided with a pair of positioning pins that match the positioning holes on the workpiece, and the lower die forming block is provided with positioning avoidance holes for avoiding the positioning pins, the positioning of the workpiece is made more reliable.

[0014] Since a pair of mold closing guide columns are provided on the upper mold mounting plate, and a mold closing guide seat matched with the guide columns is provided on the lower mold base, the accuracy of mold closing is further guaranteed.

[0015] Since the upper forming block is provided with a plurality of elastic pressing pins, the workpiece is fixed before the upper forming block contacts the workpiece for processing, thereby further ensuring the processing quality. BRIEF DESCRIPTION OF THE DRAWINGS
