摘要
利用叉车配合吊装等传统的模具更换模式通常需要花费大量时间去找准模座和设备的定位,换模效率较低。针对某锻造自动化生产线上63000 kN压力机的具体情况,同时为了避免因压力机检修平台占用较大的空间范围而对模具吊装造成的影响,提出采用两级传动的快速换模装置,节省成本的同时达到了快速换模的目的。此外,采用液压式夹模机构锁紧模架代替由T形螺栓加螺母预紧模架的传统形式,在拆卸及安装模架的过程中大大地减轻了操作人员的工作强度,提高了工作效率。经过生产验证,该快速换模技术可以明显提高齿轮锻造自动生产线上的换模效率,也为其他产品的锻造自动化生产线上的换模方案提供了借鉴和参考。
Traditional mold replacement modes such as using forklift to coordinate lifting usually takes a lot of time to find the positioning between mold base and equipment,and the mold change efficiency is low.Therefore,according to the specific situation of a 63000 kN press in a forging automatic production line,and in order to avoid the influence of the larger space occupied by the press maintenance platform on the mold hoisting at the same time,a two-stage transmission rapid mold change device was adopted,which saved costs and achieved the purpose of rapid mold change.In addition,the hydraulic clamping mold mechanism was used to lock the mold formwork instead of the traditional form of preloading the mold formwork by T-bolts and nuts,which greatly reduced the work intensity of operator and improved the work efficiency during the process of disassembling and installing the mold formwork.After production verification,the results show that the rapid mold change technology can obviously improve the efficiency of mold change in gear forging automatic production line,and also provides a reference for the mold change scheme on the forging automatic production line of other products.
