一种汽车轮毂轴承挤压成形方法
摘要：
本发明提供一种汽车轮毂轴承挤压成形方法，该方法包括将金属棒料进行剪切形成金属坯料，将金属坯料进行加热后镦粗形成饼坯，将饼坯放入挤压模具中进行挤压形成锻压毛坯，对锻压毛坯进行冲孔、切飞边、热处理，并将之进行机加工形成汽车轮毂轴承。采用挤压的方式进行汽车轮毂轴承加工，提高了材料的利用率，且利用中频电炉上设置的测温探头对金属坯料的温度进行监测，使温度范围内的金属坯料输出到镦粗设备进行加工，保证金属坯料的晶像组织以及产品机械性能，使加工后的轮毂轴承符合使用要求。
摘要（英）：

The invention provides an automobile hub bearing extrusion forming method. The method comprises the steps that a metal rod is sheared into a metal blank, the metal blank is heated and then subjected to upsetting, a biscuit is formed and placed in an extrusion die to be extruded, and a forged blank is formed and subjected to punching, flash trimming and heat treatment and machined into an automobile hub bearing. The automobile hub bearing is machined in an extrusion mode, the material utilization rate is increased, the temperature of the metal blank is monitored through a temperature measurement probe arranged on a medium frequency furnace, thus, the effect that the metal blank in the temperature range is output to upsetting equipment to be machined is ensured, and the crystalline phase structure and product mechanical property of the metal blank are ensured, so that the machined hub bearing meets the using requirement.
