碟簧机构在热冲切复合模中的应用

Application of Disc Spring Mechanism in Hot Punching-Trimming Compound Die

链轨节热锻件在冲孔、切边过程中,受到冲孔、切边剪切力的影响,容易产生变形,通过碟簧压紧机构在冲切过程中给锻件施加一定的压紧力,可消除剪切力的影响,从而使锻件不产生变形或变形程度控制在要求范围内,达到校正后的目的。实际生产证明,该模具结构设计合理,能够满足锻件质量和批量生产的要求,且操作简单、安全可靠,降低了生产成本,提高了生产效率。

In the process of punching-trimming,the hot forging of chain rail joint is easily deformed because of the shearing force of punching-trimming.By applying a certain compressing force to the forging in the process of punching-trimming,the influence of shearing force can be eliminated,so that the forging does not produce deformation or the degree of deformation can be controlled within the required range,corrected purpose.Practical production has proved that the die structure design is reasonable,can meet the requirements of forging quality and mass production,and the operation is simple,safe and reliable,reduce production costs,improve production efficiency.
