Abstract
Description
Technical Field
[0001] This application relates to the field of hot forging presses, and more particularly to a heating die holder for a hot forging press. Background Technology
[0002] Hot forging presses are indispensable high-precision forging equipment in modern forging production. During the operation of hot forging presses, for some special alloys with high strength, high hardness, or poor forgeability, the forging die needs to be heated before forging, and temperature control and heat preservation are also required during the forging process.
[0003] Currently, there are two main methods for heating molds: flame heating and electric heating. Flame heating uses an open flame, posing certain safety hazards. Therefore, most hot forging presses currently use electric heating. Electric heating can be divided into two methods: direct heating of the mold and heating of the mold base body. However, the direct heating method requires mounting holes in the mold to install heating rods and thermocouples. When the mold needs to be disassembled for maintenance, the heating device and electrical wiring must also be disassembled, making the disassembly process complex. Heating by heating the mold base body to transfer heat to the mold requires a longer heating time, results in greater energy consumption, and necessitates the addition of a heat insulation device between the mold base body and the hot forging press equipment.
[0004] In response to the aforementioned related technologies, the inventor provides a heating die base for a hot forging press. Utility Model Content
