汽车左/右上角加强板的侧修边冲孔-分离模设计是成形汽车左/右上角加强板的关键,汽车左/右上角加强板的冲压成形建立在拉延模、侧边冲孔模基础上。根据该零件的结构形状特点进行侧修边冲孔-分离模具设计,在设计过程中,针对3个模具结构设计的重点问题进行了分析讨论与确定:(1)解决了模具定位困难,由于模具加工的部位主要集中在侧向位置,需要在此处单独设置定位装置;(2)解决了分模困难,由于需要侧向冲孔,在模具设计过程中,需要防止发生侧向干涉现象;(3)解决了侧向凸模的定位及行程难以控制,需单独设置侧向行程装置。生产实验表明,最终的模具设计可以保证产品质量,达到预期设计目的。
Car left / right corner of the side trim trimming punching - Die design is forming the car left / right corner of the stiffener of the key, the car left / right corner stiffener stamping forming based on the drawing die, punch the side of the model basically. According to the structural characteristics of the part side trimming punching - separation mold design, in the design process, focusing on the three mold structure design of the key issues were analyzed and determined: (1) to solve the mold positioning difficulties, because the mold (2) Solve the difficulty of parting, due to the need for lateral punching, in the mold design process, the need to prevent the occurrence of lateral interference; ( 3) to solve the positioning of lateral punch and stroke is difficult to control, need to set up a separate lateral stroke device. Production experiments show that the final mold design can ensure product quality, to achieve the desired design.
