自动门讯:
    4片轮架型材同时弯曲
    4片铝型材同时精下料,用锯床下料,用定位装置保证弧长误差为士Immo
    艳架铝型材连接板加工。轮架铝型材共4片,用连接钢板连接,用螺钉连接,连
技术要求;1.未注倒角1×45'1 2.去锐角R0.3 1 3.调质T235
接板为厚lOmm钢板,先按图在铣床上下料再滚圆,圆弧半径达到图纸要求并打孔。
   将4片轮架铝型材用连接板连接起来,形成一个圆环,螺钉的头套在轮架铝型材
的槽中,用连接板穿过螺钉,拧紧螺钉、螺母和弹簧垫圈,使4片轮架型材成为一个整体
圆环。
   对轮架型材整环加工孔,按图示位置钻6个4150mm的孔.6孔用于装主动轮和
辅助轮。孔位先划线,再用专用钻孔设备钻孔,保证孔的质量。
    槽钢组合梁的加工制造。
    1)槽钢下料,锯床切料,然后铣床按尺寸精铣截面,达到尺寸要求。
 2)连接两槽钢的钢板和槽钢
下料、加工,连接用钢板按图铣四
边,连接用短槽钢也按图下料
加工。
    3)连接钢板与两主粱的槽钢
焊接,两根槽钢焊成旋转组件主要
受力的粱,焊后打孔。
    4)短槽钢与轮架铝型材用螺
钉活动连接,短槽钢再与焊好的槽
钢组合梁用螺钉、螺母、,弹簧垫圈
相连。
    5)对组合梁和全部钢件喷防
锈漆,再喷装饰漆,一般用红丹防
锈漆和黑色装饰漆。

技术要求:1.未注倒角l×45'1 2.去锐角R0.3*3.调质T235
    6)用螺钉、螺母、弹簧垫圈固定两翼旋转门的推拉门挂架,挂架下料、打孔要准确。
    7)加T下盘零件,喷黑色装饰漆,用螺栓固定在槽钢上,下盘是支撑吊顶板内径的
零件。
