粘着区是影响辊锻前滑大小的关键因素。本文通过实验,研究主要因素对粘着区的影响规律,分析和验证粘着区对前滑的影响。研究表明,粘着区的大小,可通过确定坯料尺寸、模块半径和接触表面的摩擦系数等因素来控制。对于尺寸精度要求较高的辊锻情况,前滑计算应在考虑粘着区存在的条件下进行,其结果更符合实际情况。 The adhesion area is the key factor that affects the size of slip before roll forging. In this paper, the influence of the main factors on the adhesion area is studied through experiments, and the influence of the adhesion area on the front slip is analyzed and verified. Studies have shown that the size of the adhesive area can be controlled by factors such as the size of the blank, the radius of the module and the friction coefficient of the contact surface. For the roll forging with higher dimensional accuracy, the calculation of the forward slip should be carried out in consideration of the existence of the adhesion zone, and the result is more in line with the actual situation.
