板成形网格测量技术板成形网格测量技术grid measuring technique of sheet metal formingbanehengxing wangge Celjang iishu板成形网格测里技术(grid measuring teeh-nique of sheet metal for粤ing)薄板成形前在表面上制作特定的坐标网格,冲压成形后测定网格的变化,以确定薄板成形过程中的塑性应变大小及应变分布状况的试验方法。利用网格测量技术,能够确定薄板制件的大应变区域并决定其变形的方式,提供在剧烈变形的区域金属流动以及模具控制金属流动的图示,进行板成形应变分析,从而为制定最佳成形工艺或改进工艺提供依据。坐标网格普遍采用圆形网格。圆形网格的直径为5、2.5或2.omm,其精度通常为士l%。对于像汽车覆盖件那样大的制件,也可采用直径为10~Zomm的圆形网格。圆形网格直径的选择在很大程度上取决于网格区域内的应变梯度,要求分析的应变特性越清晰,所选圆形网格尺寸应越小。制作圆形坐标网格的方法有划线法、电化学腐蚀法、印像法等。圆网格模式有图1所示的方格圆、叠合圆和邻接圆3种。方格圆模式(图la)可获得最大的应变测量精确度,但无法测量圆格之间区域的应变。叠合圆模式(图lb)无此缺点,但测定繁杂。邻接圆模式(图1‘)中的切点降低了测量精确度。瓢纂翼 a bc图l圆形网格模式a一方格画;b一登合四;c一邻接国可根据测量精确度的要求,采用不同的应变量测量技术。对于要求不很精确的测量(如观察变形的趋势),用简单的软尺测量就能满足。用比长仪或工具显微镜可以得到较高的测量精度。一般,对冲压车间,有带应变百分数刻度的软尺或透明塑料量具已足够。采用这类工具,可以测量制件的全部或一个部分的应变量。成形前后网格变化的测定如图2所示,圆变形成椭圆时,测定椭圆长轴a和短轴b的长度,按下式计算最大主应变e,(。1)和最小主应变。:(。2):②一皿 ub图2成形前后网格变化的测定a一成形前;b一成形后 ,、,一一“一d。b一d。公称应变。1二竺二型,。2一卜子巴之。I’J,~~“‘d。’“d。 一’‘一一ab 对数应变自一‘“言,甸一’”禽绘制el(。1)~e:(。2)应变量值曲线并与制件其他部分圆网格的测量值进行比较,或与位置相同、材料不同的制件的测量值相比,还可与冲压条件不同的测量值比较,以确定可能的最佳工艺组合,使应变峰值尽可能减小。利用测量结果还可绘制出制件表面的等应变分布图。(邓涉)
