某型舰炮挡弹板装置在使用过程中主要起限制弹壳或教练弹抛出安全范围作用,但在使用过程中发现有个别档弹板出现了裂纹。本文针对裂纹产生的原因,从零件状态、工艺流程和材料裂纹检测等方面进行分析,找出原因并制定改进措施,保证产品的性能和质量。 A certain type of naval gun retaining plate device mainly plays a role in limiting the scope of the safety of the shell or the coaching shell in the course of its use. However, cracks have been found in some types of elastic plates during use. In this paper, the causes of cracks, from the parts state, process flow and material crack detection and other aspects of analysis to find out the reasons and to develop improvements to ensure product performance and quality.
