Abstract

Deep drawing processes play a pivotal role in the manufacturing of sheet and shell products, making it a widely adopted method. This research employs numerical simulations to investigate the impact of various process parameters on the fracture height of cylindrical cups made from SECC (Steel Electrogalvanized Commercial Cold rolled) material. Specifically, it examines parameters such as blank holder force (BHF), punch corner radius (Rp), die corner radius (Rd), and punch-die clearance (Wc). The study extends to optimizing fracture height, offering a solution to this challenge. Subsequently, the selected parameters are validated through experimental deep drawing of cylindrical cups, resulting in a minimal deviation of 1.55% between simulation and experiment outcomes. A precise mathematical equation is developed to estimate fracture height under diverse machining conditions, with a maximum deviation of 4.52% observed between the mathematical model and simulation. These findings represent a substantial advancement in deep drawing processes technology, particularly in reducing error rates during the production of cylindrical cups .

SECC 圆柱杯深拉工艺中断裂高度的优化与建模

深冲工艺在板材和壳体产品的制造过程中起着举足轻重的作用，因此被广泛采用。本研究利用数值模拟来研究各种工艺参数对 SECC（电镀锌商业冷轧钢材）材料制成的圆柱杯断裂高度的影响。具体而言，研究了坯料夹持力 (BHF)、冲头转角半径 (Rp)、模具转角半径 (Rd) 和冲头-模具间隙 (Wc) 等参数。研究扩展到优化断裂高度，为这一挑战提供了解决方案。随后，通过对圆柱形杯的深冲实验验证了所选参数，结果发现模拟结果与实验结果之间的偏差最小，仅为 1.55%。建立了一个精确的数学方程来估算不同加工条件下的断裂高度，观察到数学模型与模拟结果之间的最大偏差为 4.52%。这些发现代表了深冲工艺技术的巨大进步，特别是在降低圆柱杯生产过程中的误差率方面。
