管材旋转模冷拔管材旋转模冷拔cold drawing of tube through revolving die 的主动旋转外模与顶头(或芯棒)之间拔制管材的工艺(见图)采用旋转模拉拔,拉拔的部分变形为滚轧所取代,滚珠或滚柱与管材接触表面之间为滚动摩擦。摩擦系数小,可以降低拔制力。这对薄壁管和低塑性材料的拉拔很有利。但是,旋转模冷拔管材存在以下的缺点:(1)旋转槽内滚珠或滚柱的咬入角较小(镇15。),睿二瑙 滚珠式旋转模的结构及拔管过程 l一端支持环;2一安装在旋转支持器内的模套; 3一管材;4一芯棒guaneai xuanzhuanmu lengba管材旋转模冷拔(eold arawing of:ub。thro-u只h revolving die)室温下在装有滚珠或渡杜使得每转的减壁量不能取大,一般小于滚珠或滚柱直径的2%;(2)为防止管体表面出现螺旋线,旋转模每转动一次管材的轴向送进量必须很小,对于滚珠组装的旋转模,约为管材周长的2%一4%;(3)模内相互接触的滚珠或滚柱体之间以及它们与模套之间摩擦能耗的比重也很大。由于上述原因,旋转模冷拔管材未能在大生产中广泛应用。 (周忠民)
