What is the main cause of heat generation during hot working of dies?
The main reasons why the mold is heated during hot working are as follows:
1. Internal friction of materials: During processing, internal friction will occur due to deformation and displacement of materials, thus generating heat.
2. Plastic deformation: In the process of processing, the material will undergo plastic deformation, thus generating heat.
3. Heat treatment: In order to improve the performance of the material, the mold will be heat treated, which is one of the main reasons why the mold is heated.
4. Heat source: In hot working mold processing, blowtorch, stove and other heat sources are usually used to heat the mold.
5. Friction heat: In the process of machining, due to the friction between the material and the tool, heat will be generated, thus heating the mold.
