轮毂锻造液压机垫板隔热保温结构优化

Heat insulation structure optimization of the pad of wheel hub forging hydraulic press

铝合金轮毂热锻工艺中,要求在减少模具温度散失并控制成形温度在工艺要求内,有效提升轮毂成形的机械性能、物理性能及轮毂锻造效果和成品率。液压机中垫板结构在隔热保温方面起到了相关关键的作用。轮毂成形为中心载荷,垫板隔热层隔热的同时还要满足抗压效果。将隔热板置于固定垫板与压机横梁之间,目的是减少模具的热量传递,保证产品品质,减少热量损失,延长设备使用寿命。

In aluminum alloy wheel hub hot forging process,reducing die temperature loss and controlling the forming temperature can effectively improve the mechanical and physical properties of hub forming,as well as the effect and yield of hub forging.The pad construction in the hydraulic press plays a key role in the thermal insulation.Hub forming is the central load,the thermal insulation layer of the pad has the function of heat insulation,but also to meet the pressure requirements.The purpose of placing the heat insulation board between the fixed pad and the press beam is to reduce the heat transfer of the mold,ensure the quality of the product,reduce the heat loss,so as to extend the service life of the equipment.
