一种对装销轴用砸销模具
本技术涉及一种链条修整模具,尤其涉及一种对装销轴用砸销模具。
技术介绍
一根完整链条包括半外节装配,内链节装配,成条装配、露头和铆头。销轴和外链板配合组成半外节,即砸销。在链条成条装配过程中往往会出现严重的切边毛刺,导致销轴的拉毛磨损,大大影响链条的品质,砸销质量的好坏程度将会影响链条的质量。在链条设计中,大孔外链板一般设计为圆孔,小孔外链板设计为扁孔,防止链条成条后销轴的转动,销轴和大孔外链板配合形成半外节,既要保证砸销后的垂直度要求,还要保证成条时销轴扁向与小孔外链板孔扁向的同心度和平行度要求。特别对于对装销轴的砸销,链板上一个圆孔一个扁孔,圆孔跟单根销轴装配成半外节,两边半外节相互对装中间放置一个内链节串装成条为链条,针对对装销轴链条成条装配中出现严重的切边,导致销轴拉毛磨损的现象,我们针对对装销轴的装配设计了一种对装销轴用砸销模具。本技术根据实际生产过程中的链板往往存在切边毛刺的现象,公开了一种对装销轴用砸销模具,模具采用异孔定位销定位外链板扁孔,异孔定位销采用铣扁结构,与定位销座采用过盈配合,防止异孔定位销和定位销座之间转动,起到 ...
