成型的零件是一个“几”字形的弯曲件。
3)模具的工作原理
答:首先进行备料,然后按照要求裁剪一定宽度的条料。工作时,用手按入条料,使用型芯(挡料销的作用)进行限定条料的初始位置,进行冲孔,冲孔废料在卸料螺钉的作用下从下孔掉落。型芯往上移动时,条料在卸料板的作用下掉落。条料依旧用手按入,条料进入下一个步距,以垫块为定位,弯曲时以装在弯曲凹模上的塑料导正销进行精确定位,保证条料上孔和弯曲件的相对位置精度。上模部分往下运动对条料进行弯曲变形。
2、模具拆卸过程
步骤1:首先了解各副模具的总体结构,仔细观察各零件的位置和相互关系,并分析它的工作原理。;
步骤2:将模具的上、下模分离,观察各部分的结构组成及固定方法;
步骤3:分别拆开模具的上模部分,弄清楚模具零件组成,分析模具结构的合理性,将上模座上的销钉旋开,分析导柱导套的配合位置,以及冲孔凸模和弯曲凹模的固定位置和连接方式,做好弯曲凹模和其固定板的配合方式。
步骤4:分别拆开模具的下模部分,弄清楚模具零件组成,分析模具结构的合理性,下模座上的销钉旋开,将弯曲凸模(包括垫块、挡料板、凸模块)和冲孔凹模的固定方式确定好,分析卸料和送料的方式。
步骤5:将拆好的模具形象的表现在二叉树上。
