对某直角弯头的锻压工艺进行改进,将传统的一模一件锻压改为一模两件锻压,对锻件排列方式、型槽间距、毛坯形状尺寸等进行了设计与计算。采用Deform-3D软件对一模两件锻压成形过程进行模拟仿真,对仿真中的模型构建、参数设置等做了说明,得到成形过程中的载荷-行程曲线和成形结束时的等效应力分布。模拟结果表明,产品在成形过程中能充满型腔,锻造成形过程合理。将仿真中的参数应用于生产实际,通过小批量试制生产,产品完全符合使用要求。实际生产证明:一模两件锻压的生产效率提高了5倍,模具的使用寿命提高近2倍,产品的生产成本节约了8230元/3000件。
A right-angle bend of the forging process was improved, a traditional molding a forging die to a two forging, forgings arrangement, groove pitch type, shape and size like the blank design and calculation. Using Deform-3D software forging forming process a mold two to simulate, for simulation modeling, parameter settings do described, to obtain a molded during loading - the equivalent stress at the end of the trip curve and shape distribution. The simulation results show that the product can fill the cavity during the forming process and the forging process is reasonable. The simulation parameters used in the actual production, trial production through small batch production, the product fully meet the requirements. The actual proof of production: a die two forging the production efficiency increased by 5 times the mold life increased nearly 2 times the product cost savings of 8230 yuan / 3000.
