Description

Technical Field

[0001] The utility model relates to the technical field of valve body forging, in particular to a valve body forging die. Background Technique

[0002] At present, most valve bodies are produced by the free forging method. Free forging is a processing method that uses impact force or pressure to make the metal freely deform in all directions between the upper and lower anvil surfaces without any restrictions to obtain forgings with the required shape, size and certain mechanical properties. The billets produced by free forging have a large weight, resulting in waste of materials, and the product surface is rough with a large margin; the existing die forging means that the metal is first heated to a liquid or softened state, and then it is placed in a die, and one or more forming operations are completed by closing the upper and lower dies of the die.

[0003] A valve body forging die with the publication number of CN218532673U includes a lower die, an upper die and a water guide pipe. Cooling grooves are respectively arranged inside the lower die and the upper die. A first liquid inlet pipe and a second liquid inlet pipe are respectively connected to one side wall of the lower die and the upper die. One ends of the first liquid inlet pipe and the second liquid inlet pipe are both connected to the cooling groove. A connecting pipe is connected between the water guide pipe and the first liquid inlet pipe, and a metal hose is connected between the water guide pipe and the second liquid inlet pipe. The other side wall of the cooling groove is connected with a liquid outlet pipe. By arranging the water guide pipe, the connecting pipe, the metal hose and the cooling groove, the external cold water source can enter the cooling groove, so that the cooling groove can continuously cool down. Moreover, the water supply of the lower die and the upper die is consistent, which can ensure the consistency of temperature reduction between the two modules, avoid the influence of different temperatures of the two modules on the workpiece forming, and ensure the stability of the workpiece forming. However, this die needs to be continuously opened and closed up and down. During the process of repeatedly closing and opening the die up and down, it is easy to cause wear and even damage to the contact surface, resulting in a decrease in the forging precision of the die. At the same time, this equipment lacks limit for vertical die opening and closing and is prone to deviation.
