Abstract
The utility model relates to the technical field of forming dies, and discloses a square cylinder hole flanging die which comprises an upper die base and a lower die base, a hole flanging female die is arranged on the upper die base, a material pressing plate and a hole flanging male die are arranged on the lower die base, and the material pressing plate is designed in a floating mode relative to the hole flanging male die. In the die opening state, the upper surface of the material pressing plate is higher than the top end of the hole flanging male die so as to support a square cylinder workpiece to be machined, and the molded surface of the upper surface of the material pressing plate is matched with the surface shape of the square cylinder workpiece. In the die assembly state, the lower surface of the material pressing plate abuts against the lower die base, the upper surface of the material pressing plate is matched with the hole flanging female die to clamp a square cylinder workpiece, and the top end of the hole flanging male die is exposed out of the material pressing plate and matched with the hole flanging female die to achieve hole flanging. According to the square cylinder hole flanging die, the square cylinder workpiece is reliably clamped and accurately positioned, the hole flanging forming quality is guaranteed, hole flanging machining with low cost can be achieved by simplifying the die structure, controlling the die size and being used in cooperation with some small pressing machines, and the purposes of reducing cost and improving efficiency are achieved.
