矿用液压软管接头芯子径向锻造工艺的研究

目的随着我国煤炭、钢铁业的新发展,矿用液压软管接头因更换快、使用量大,迫切需要新的成形工艺。方法针对KJ-25型液压软管接头芯子,提出了一种采用径向锻造近净成形制造毛坯的工艺。通过三维有限元软件FORGE建立了工艺的三维有限元模型,并对成形力、工件温度及应力状态进行了分析。结果有限元模拟结果表明:径向锻造生产的坯料较切削加工可节材37%,温锻时单个锤头锻造力仅为37.3 t。结论径向锻造工艺适用于同类型软管接头芯子的毛坯制造。

Research of Radial Forging Process for Inner Sleeve of Hydraulic Hose Coupling Using in Mine Industrial

Objective With the development of the coal and iron mine industry, the forming process of hydraulic hose coupling, which is of great importance in these industries, has drawn much attention in recent years. Methods A radial forging process to manufacture the inner sleeve billet of the KJ-25 hydraulic hose coupling using in mine industrial is performed. A FE model of the process is established under the software environment of FORGE. And the forming force, the temperature field and the stress state of the workpiece is studied with the FE model. Results Comparing with traditional cutting process, the material utilization of the radial forging process is decreased by 37%. And the forming force of each die is measured to be only 37. 3 tons under warm forging. Conclusion The radial forging process may be of general significance to form the billet of this kind of parts.
