[0002] A flange, also called a flange plate or flange, is a part used to connect pipes to each other, for connecting the pipe ends; flanges are also used on equipment inlets and outlets to connect two pieces of equipment. When using flange connections, holes are punched on the surface of the flange to allow the connecting parts to be inserted and tightened.

[0003] Currently, flange punching is generally performed using a drilling machine. The flange is first positioned inside a tooling tray, and then the drilling machine is lowered to drill holes in the flange surface. After drilling, the flange is removed from the tooling tray, and debris is cleaned from the tray. A new flange is then placed inside the tooling tray, tightened, and drilled again. However, the loading and unloading of flanges and the cleaning of the tooling tray are quite cumbersome and take up valuable drilling time, resulting in low overall efficiency of the flange punching device and making it difficult to meet the needs of rapid processing.
