薄板制耳性能评价方法的探讨
|
摘要
主要对制耳率及其计算方法进行了探讨,指出了现有制耳率公式在某些制耳情况下存在评价不充分的不足,并对制耳率计算公式进行了新的探讨。传统的制耳率公式着重考虑了制耳峰及制耳谷的平均高度,但对制耳峰及制耳谷的宽度及面积情况反映不充分。在实际生产中,制耳现象对深冲材料的利用率影响很大。从实际出发,侧重于制耳评价方法对深冲材料裁边面积及材料利用率的反映,对制耳率计算公式进行了新的探讨。与传统制耳率公式相比较,该新公式可以弥补传统公式的不足,形成优势互补。
The discussion about the earing ratio and its calculation method is presented. The existing formula of earing ratio has evaluation deficiencies in some cases and new calculation formula is discussed. The traditional formula focuses on the average height of the earing peak and earing valley,while the response to the width and area of earing peak and valley is insufficient. In fact,the phenomenon of earing has a great influence on the utilization rate of materials for deep drawing. Based on actual condition,it focuses on the response of the earing evaluation method to the cutting area and utilization rate of materials for deep drawing. A new discussion about the calculation formula of the earing ratio is presented. Compared with the traditional formula,this new calculation formula of the earing ratio can make up for the deficiencies and form complementary advantages.
