在煤矿机械制造业中,热压成形是生产采煤机滚筒螺旋叶片的传统方法。虽然热压成形的质量较好,但生产率低、劳动条件差、能源消耗大、胎具制造成本较高、工艺过程复杂。从我厂五年多的生产实践和兄弟厂推广使用后证明,采用转位冷压胎冷压叶片是成功的。本文叙述了转位冷压胎的设计方法及应考虑的几个工艺问题。 In the coal mining machinery manufacturing industry, hot forming is the traditional method of producing shearer’s spiral drum blades. Although the quality of hot forming is good, but low productivity, poor working conditions, energy consumption, high cost of manufacturing tools, process complexity. From our plant more than five years of production practice and promote the use of brothers plant proved that the use of indexing cold tire pressure is successful. This article describes the design method of indexing cold tire and several technical problems to be considered.
