There are many precise and complex molds in the heat treatment process, so it is necessary for the processors to have correct methods. Next Jinan mold to give you an analysis.
1. Reasonable material selection. It is necessary to select high-quality micro deformation abrasive steel for the mold with complex density, forge and heat treat the abrasive steel with severe carbide segregation, and carry out solution and double refining heat treatment for the abrasive steel with large or unable to forge.
2. The design of the mould shall be reasonable and the shape shall be symmetrical. The deformation rule of the larger mould shall be well mastered and machining allowance shall be reserved. The large and sophisticated mould can adopt the combined structure.
3. The mould shall be pre heat treated.
4. The reasonable choice of heating temperature and control temperature can be achieved by slow heating, preheating and other balanced heating methods to reduce the deformation of mold heat treatment.
5. If conditions permit, vacuum heating quenching and deep cooling after quenching shall be adopted as far as possible.
In addition, the correct heat treatment process operation and reasonable tempering heat treatment process are also limited measures to reduce the deformation of precision complex mold. For more information, please click Jinan mould http://www.jnhjgs.cn Official website.
