摘　　要：通过锁定臂的实际生产需求进行多工位级进模排样设计,根据锁定臂零件的结构特点,采用单排排位结构。模具整体采用顺装结构,每次冲裁过程中产品和废料自动分离。凹模采用镶拼结构,加工更加方便,模具保养更加简单,易损件也更加便于更换。双侧刃布置在导料槽两边,入模料边形成定位缺口,紧贴凹模沿导料槽送进,可以连续冲压,使压力机行程次数利用率达到100%,生产效率高且安全,也便于冲压过程的机械化与自动化。为了保证冲压的精度和零件的精度,在冲裁工位中设计了导正销,并采用了逐次弯曲成形工艺,以减少弯曲过程中的回弹。最终通过实际生产验证,设计的锁定臂多工位级进模能够满足实际生产需求。The design of multi-station progressive die layout was carried out by the actual production demand of locking arm, and the single layout structure was adopted based on the structural characteristics of locking arm parts. Then, the whole die adopted the sequential structure, and the part and scrap were separated automatically during each punching process. The concave die adopted the insert structure, which was more convenient to process and easier to maintain the die and replace the wearing parts. The double side edges were arranged on both sides of guide slot, and the material edge entering the die formed a positioning notch, which was fed along the guide slot close to the concave die. Therefore, the continuous stamping was possible, so that the utilization of stroke times for press reached 100%, the production efficiency was high and safe, and it was also convenient for the mechanization and automation of the stamping process. In order to ensure the accuracy of stamping and parts, the guide pin was designed in the blanking station, and the bending process one by one was adopted to reduce the springback in the bending process. As a result, through the actual production verification, the designed multi-station progressive die of locking arm could meet the actual production requirements.
