Description

Technical Field

[0001] This utility model relates to the field of forging hydraulic press technology, and in particular to a forging hydraulic press for 16Mn pressure vessel steel forgings. Background Technology

[0002] 16MnR: 16MnR is a common low-alloy steel, a special steel for boilers and pressure vessels, and a commonly used material for boilers and pressure vessels. It has high strength, good plasticity and toughness, and pressure vessel forgings are generally formed by forging with a hydraulic forging press.

[0003] In the prior art, Chinese patent CN210996259U discloses a forging hydraulic press for pressure vessel steel forgings, including a machine body, several columns fixed at the upper end of the machine body, a groove opened on one side of the inner surface of the column, an oil collecting cylinder fitted and connected to the bottom end of the inner surface of the groove, a forging seat fixed on the inner side of the column at the bottom end of the machine body, and a hydraulic seat arranged on the inner side of the column above the forging seat, the hydraulic seat can slide linearly up and down in the groove through a fixed rod, a sliding rod and several sliding balls arranged around the outside of the sliding rod.

[0004] The forging hydraulic presses proposed in the above patent documents lack a structure for limiting and adjusting the two ends of the forgings during actual use.
