【摘要】：水基拉延油是一种水溶性拉延油,是碳钢板冲压用油,与市场上油基拉延油比,冷却性、润滑性和抗极压性更好,节省冲压件除油工序,可用自来水冲洗、具有阻燃性、安全环保,尤其适合复杂件的重度拉伸应用。由于不同的生产方式使用不同的方法如：喷涂,挤压涂抹,手工涂抹等,这就需要不同粘度的水基拉延油配合。所以粘度是水基拉延油一个重要的使用指标,要建立粘度模型来精确地控制粘度。水基拉延油粘度与材料种类、混合比例和温度有关。水基拉延油是牛顿型流体和非牛顿型流体的混合体系,无法用现有的粘度模型进行粘度预测,但是可以从经典的粘度模型中找出预测效果最好的粘度模型,用不同配比在不同温度下的实验测量值进行回归预测,修正模型,从而得到针对水基拉延油混合体系的粘度模型。在本文中,选取经典的牛顿体系模型Arrhenius模型,Bingham模型,Kendall-Monroe模型和Cragoe模型；非牛顿体系Roscoe模型；双参数模型ASTM模型。并利用拟合优度进行评价,通过拟合系数比较,找出最接近的预测粘度模型。通过对十个不同混合比例样品的九十个粘度测定值进行预测比较,ASTM模型预测效果相对其他5个粘度模型最好,而且精确度可以进一步提高。用实验测量值对ASTM模型进行修正,得到M-ASTM粘度模型,拟合系数从0.860提高到0.991。M-ASTM粘度模型可以精确地预测水基拉延油粘度的变化,也可以根据粘度要求和温度要求反向求出混合比例,进一步指导生产。
[Abstract]:Water based drawing oil is a kind of water soluble drawing oil. It is a kind of carbon steel plate stamping oil. It has better cooling, lubricity and resistance to extreme pressure than oil based drawing oil on the market. It can save stamping parts in the deoiling process, can be flushed with tap water, and has flame-retardant property. Safe and environmentally friendly, especially suitable for heavy tensile application of complex parts. Because different production methods use different methods, such as spray, extrusion, hand smear, etc., this requires different viscosity of water based drawing oil. So viscosity is an important index of water-based drawing oil. Viscosity model should be established to control viscosity accurately. Viscosity of water-based drawing oil is related to material type, mixing ratio and temperature. Water-based drawing oil is a mixed system of Newtonian fluid and non-Newtonian fluid, which can not be predicted by the existing viscosity model, but the best viscosity model can be found out from the classical viscosity model. The viscosity model of water based drawing oil mixture system was obtained by regression prediction and modification of the model by using the experimental measurements at different temperatures. In this paper, the classical Newtonian system model, Arrhenius model, Kendall-Monroe model and Cragoe model, the non-Newtonian system Roscoe model and the two-parameter ASTM model are selected. According to the comparison of the fitting coefficients, the nearest predictive viscosity model is found. The prediction results of 90 viscosity measurements of ten samples with different mixing ratios were compared with that of the other five viscosity models, and the accuracy of ASTM model could be further improved. The ASTM model is modified by the experimental measurement value, and the M-ASTM viscosity model is obtained. The coefficient of fitting is increased from 0.860 to the 0.991.M-ASTM viscosity model, which can accurately predict the change of the viscosity of water-based drawn oil. Can also be based on viscosity requirements and temperature requirements to reverse the calculation of mixing ratio, further guide production.
