铝及铝合金板拉延时一直采用机械油或豆油直接润滑。机械油的润滑性能差、粘附力小、粘度低、无耐热性和绝热性。所以拉延件的外观质量不稳定、模具寿命低、生产效率低、工人劳动强度大和洗净性差(采用豆油时)。在生产批量小(手工送料)时,基本上可以满足设计要求,在生产批量较大(自动送 Aluminum and aluminum alloy plate drawing has been using mechanical oil or soybean oil direct lubrication. Lubricating performance of mechanical oil is poor, small adhesion, low viscosity, no heat resistance and thermal insulation. Therefore, the quality of the appearance of the drawing parts of the unstable, low mold life, low productivity, labor-intensive and poor cleaning (when using soybean oil). In the production of small batch (manual feeding), basically meet the design requirements in the production of large quantities (automatically sent
