Description

Technical Field

[0001] The invention relates to the technical field of forging dies, in particular to a forging die for a water meter shell. Background Art

[0002] The water meter shell is an important component of the water meter. It is often forged and processed by forging dies during production. The water meter shell forging die is installed on the forging machine, and the red-hot copper rod and other materials are punched into the mold of the water meter shell at one time. Using the water meter shell forging die to forge the material can improve production efficiency and product quality.

[0003] For example, publication number: CN109201999A discloses "a forging die for a water meter shell", which adopts a water meter shell cavity formed by merging a pair of half mold cores, the mold core is installed in a mold base with an inclined outer wall formed by merging a pair of half mold bases, a core pulling slider is arranged at the open part of the half mold base, the half mold base is installed in a through cavity with an inclined wall on the side wall of the mold frame, and a push rod is installed under the mold base, and the push rod is lifted to make the core pulling slider of the half mold base and the half mold core move up along the inclined wall of the mold frame side wall and open.

[0004] However, in the prior art, because hot forging can cause the blank to produce larger deformation under lower pressure, which is conducive to the forming of complex shapes, the forging of water meter shells usually adopts hot forging technology. During the hot forging process, the blank needs to be heated to a higher temperature, generally above the recrystallization temperature. The heating temperature of the common copper water meter shell blank is between 600-900°C. When the high-temperature blank is placed in the mold cavity, according to the basic principle of heat transfer, heat will be transferred from the high-temperature blank to the low-temperature mold. Since the blank is in close contact with the surface of the mold cavity and the contact time between the blank and the mold is relatively long during the forging process, the heat will continue to be conducted to the mold. During the long-term and repeated forging process, the temperature of the mold will gradually increase. In a high-temperature environment, the thermal expansion coefficient of the mold material will cause the mold size to change, thereby destroying the original dimensional accuracy and shape accuracy of the mold. At the same time, high temperature will reduce the hardness and strength of the mold material, weaken its ability to resist deformation and wear, easily cause mold damage, and reduce the service life of the mold. Summary of the invention

[0005] The purpose of the present invention is to provide a water meter shell forging die to solve the problem that the temperature of the existing water meter shell forging die will gradually increase during the forging operation. In a high temperature environment, the thermal expansion coefficient of the die material will cause the die size to change, thereby destroying the original dimensional accuracy and shape accuracy of the die.
