压缩机活塞温锻模内腔的龟裂与改进措施

Improvement Measures of Cavity Crack of Warm Forging Die for the Compressor Piston

从模具的材料、热处理工艺、结构、受力情况、热变形等5个方面分析了压缩机活塞锻件温锻模内腔产生龟裂的原因,通过采用改进原有模具结构的设计方案、模具的材料及热处理工艺,有效解决了压缩机活塞温锻模内腔的龟裂问题。

From 5 aspects of the die material, heat treatment, structure, stress, thermal deformation, analysis the compressor piston warm forging die cavity cracking cause, through improving die structure design, the die material and heat treatment process, effectively solve the compressor piston warm forging die cavity crack problems.
