- 摘要:
- W型特种油滤网具有弹性好,抗冲击能力强等优点,在发动机管路系统广泛应用,然而,W型油滤网为薄壁、复杂横截面结构,冲压成形过程极易出现拉裂、起皱缺陷以及尺寸超差等问题,导致零件合格率低,批量报废。为解决W型油滤网冲压过程成形质量问题,基于ABAQUS有限元仿真平台,建立了W型油滤网冲压过程三维有限元模型,获得了优化工艺参数和模具结构尺寸。针对试验和试生产出现的质量问题,开展质量问题统计,获得质量控制措施,试验结果表明,采取的质量控制措施有效解决了油滤网冲压过程的缺陷问题,产品合格率提升至99%以上。优化后的加工工艺稳定,满足批量生产交付要求,说明采取的质量控制措施是合理的。该研究方法应用于“C型”特种油滤网生产,产品合格率达99%以上,研究方法具有普适性。
- Abstract:
- Because the W-type special oil filter has advantages of high elasticity and strong impact resistance, it is widely used in the engine pipeline system.However, due to thin-wall and complicated cross-sectional structure of the W-typed oil filter, the defects such as crack and wrinkle as well as dimensions out-of-tolerance easily occur in the stamping process, which results in low pass rate and batch scrap.To solve the forming quality problems in stamping process of the W-type special oil filter, a three-dimensional FE model for the filter stamping process was established and the optimized process parameters and die structure size were obtained based on the ABAQUS finite element(FE)simulation platform.Aiming at the quality problems in the test and trial production, the quality problem statistics was carried out and the quality control measures were obtained.The test results show that the quality control measures effectively solve the defects in the stamping process of the oil filter, and the qualified rate of the products increases to more than 99%.The optimized forming process is stable and it meets the requirements of large-scaled manufacturing, indicating that the adopted quality control measures are reasonable.This methodology has been successfully used in the C-typed oil filter manufacturing with a pass rate of more than 99%, and this methodology is a general opproach.
