新型黄化机的焊接生产工艺

The Welding Process Technology of New Type Huang Hua Machine

黄化机是粘胶纤维原液制备设备中的关键设备。用大型、新型黄化机替代过去的普通机型已成为市场的迫切要求。由于大型黄化机在焊后无法加工，而且对尺寸的要求严格，我们采取精确加工零件、优化焊接工艺、采用特殊工装、焊后振动消除应力等措施，减少了 焊接应力、防止了焊接变形、保 证了产品尺寸，使新产品研制工作取得了成功。

he huang hua machine is a key equipment in the preparation equipment of original liquid of Viscose fibre.It is marketable requirement that has leen replaced by new type.Because of large type huang hua machine process is difficuet and the size control is rigid,use take steps to accurate process spares,optimize welding technology,adopt special welding platen,by Vibration relieve stress postweld efc.The stress is reduced,the welding deformation is prevented and the product size is assured.The manufacture of new product is successful.
