[0002] A flange, also called a flange plate or flange, is a part used to connect shafts, for connecting pipe ends; flanges are also used on equipment inlets and outlets for connecting two pieces of equipment, such as gearbox flanges. A flange connection or flange joint refers to a detachable connection consisting of a flange, gasket, and bolts forming a combined sealing structure. Pipe flanges refer to flanges used for piping in pipeline installations; on equipment, they refer to the inlet and outlet flanges. Flanges have holes, and bolts are used to tightly connect two flanges. A gasket is used for sealing between flanges. Flanges are classified as threaded flanges, welded flanges, and clamp flanges. Flanges are always used in pairs; threaded flanges can be used for low-pressure pipelines, while welded flanges are used for pressures above four kilograms. A gasket is placed between two flange plates, and then they are tightened with bolts. Flanges of different pressure ratings have different thicknesses, and the bolts used also differ. Pumps and valves, when connected to pipelines, are also made into corresponding flange shapes, also known as flange connections. Flange forging machines are used to forge flanges.

[0003] However, current flange forging machines have the following shortcomings: Placing the flange on the forging table and removing the forged flange from the forging table both require stopping the extension and retraction of the hydraulic telescopic rod, and the flange must be placed and removed manually. Therefore, the placement and removal of the flange is inefficient and there is a risk of accidentally pressing on the hand. Utility Model Content

[0022] The lifting mechanism includes a third support connecting seat 12 welded to the bottom of the top support plate 10 and a second hydraulic cylinder 13 fixedly installed on the forging table 1. The second telescopic rod 22 of the second hydraulic cylinder 13 extends into the third support connecting seat 12 and is fixed to the third support connecting seat 12 by bolts.

[0023] In practical use, the second hydraulic cylinder 13 controls the extension of the second telescopic rod 22, thereby raising the top support plate 10 and raising the forging mechanism. The worker places the flange 3 on the first groove 20. At this time, even if the first telescopic rod of the first hydraulic cylinder 11 accidentally extends, the forging head 6 will not press on the worker's hand. Then, the second hydraulic cylinder 13 controls the second telescopic rod 22 to reset, and the forging mechanism is used to forge the flange. When the forged flange is removed, the second hydraulic cylinder 13 controls the extension of the second telescopic rod 22, causing the forging mechanism to continue to rise, and then the flange is removed to avoid accidental crushing.

[0024] Example 2, see attached document Figure 4 Unlike Embodiment 1, the groove is configured as a long groove 14, the inner wall of the long groove 14 has a sliding support platform 21, and also includes a quick-change mechanism; The quick-change mechanism includes two sliding support rings 15 on a sliding support platform 21.

The two ends of the bridging rod 16 are respectively inserted into the two fourth support connecting seats 17 and fixed to the fourth support connecting seats 17 by bolts. An electric push rod 18 is connected to one end of the front support ring 15, and the other end of the electric push rod 18 is fixedly connected to a support block 19. The support block 19 is fixedly installed at the end of the long groove 14.

[0025] In practical use, the extension and retraction of the electric push rod 18 drives the flanges 3 inserted on the two support rings 15 to alternately be positioned directly below the forging head 6, thereby moving the forged flange out of the forging head 6 while placing another flange 3 under the forging head 6, thus achieving the purpose of quickly replacing the flange 3.
