摘　　要：为满足固定支座精度高、批量大的生产需求,对其进行工艺分析后确定采用多工位级进模生产,并选择了53°斜排的排样方案,包括6个冲裁、1个弯曲、1个空工位和1个切断工位。根据排样进行了模具设计:采用向上弯曲,并降低浮料高度;弯曲凸模安装在卸料板上,设计浮料钉保证弯曲的稳定性;对细小凸模设计保护套,提高凸模强度;易磨损凸模采用快换式设计,凹模采用镶块设计,便于加工和更换;采用滚动式导柱导套对正模具间隙,保证运行平稳;采用浮动导料销、小导柱导套、导正销联合精定位,保证送进及成形精度,并设计限位块保护模具。经过试模生产,模具结构设计合理,制件的尺寸和精度均满足要求。In order to meet the production requirements of high precision and large batches for fixed supports,it was determined to use multi-station progressive die for production after process analysis,and a 53°diagonal layout scheme was selected,which included six punching stations,one bending station,one empty station and one cutting station.Furthermore,based on the layout,a die was designed,namely,the bending part was bent upward to reduce the height of floating;the bending punch was installed on the discharge plate,and floating nails were designed to ensure the stability of bending;the small punches were designed with protective sleeves to enhance the punch strength;a quick-change design was adopted for the easy-to-wear punch,and an insert design was used for the dies which was casy to processing and replace;the rolling guide posts and guide bushes were used for the precise alignment of die clearances to ensure smooth operation;the floating guide pins,small guide posts and guide bushes,and positive guide pins were used in combination for accuracy of feeding and forming,and limit blocks were designed to protect the die.The result of test shows that after trial production,the die structure design is reasonable,and the size and precision of parts meet the requirements.
