Multi-directional Forging Forming Steering Knuckle Which Is Studied By Simulation

Steering knuckle belongs to security components, the safety grade isⅠ.According to authority of the organization research found that steering knuckleusually failure due to fatigue failure, so that high mechanical properties of the carsteering knuckle is being required. Due to automotive steering complex twigs parts ofSection Department of complex shape, and even sometimes exist eccentric, resultingin the forging very difficult.Refers to the past6700and EQ153steering knuckle forging process, accordingto the multi-directional forging forming technology, intended6700the EQ153steering knuckle multi-directional forging forming process, according to thethree-dimensional modeling software UG forging model,and is being simulated byDEFORM-3D software simulation.Using the finite element software study EQ153and6700steering knuckle multi-dieforging process, the following work is being done:1. Multi-directional forging press was set as final forging equipment, and " a fire threeforging forming process” is being established, the specific process route: cutting-medium frequency induction heating-squeeze blank–squeeze head–the finishforging.2. DEFORM-3D software simulation6700EQ153automotive steering moderationblank, multi-die forging, analyze the system blank, and finally forging process flowpattern of the metal forming process stress and strain distribution, velocity field,temperature field etc., to optimize the blank size of forgings structure and the formingmold provide reliable theoretical reference.3. DEFORM-3D software simulation analysis of6700and EQ153automotivesteering knuckle restraint blank, multi-die forging equipment loading conditions,mold stress distribution, die wear, metal forming flow slip velocity distribution,predicted die life and definitely the mold structure adjustment, improve the security ofits production.Through the software simulation analysis, according to the product forming, metal flow linesis reasonable, without flash, small draft angle, forgings uniform stress and strain distribution andthe value lower final forging products, a conclusion is being drawing that it is a feasible process toforming steering knuckle. Simplifies the analysis of the analog part of the forming process, not only improve material utilization, but also reduces the forging equipment pressure to improve dielife, providing a new technology of steering knuckle forging process.
