The utility model discloses a precision machined bearing, which comprises an outer ring of the bearing, a mold, a module, a downward head and an upward head. The outer ring of the bearing is connected with the mold. The module is mounted above the outer ring of the bearing and the mold. The downward head is mounted on the module, and the outer ring of the bearing and the bottom of the mold are mounted on the upstream head. A precision machining bearing can precisely process the special cavity of bearing outer ring, which ensures the precision of machining and improves the quality of finished products. Compared with the traditional outer ring special cavity formed by cutting tools, the utility model uses the plasticity of the material to extrude the outer ring blank of the bearing slowly along the straight line, not only does not produce the cutting waste, but also makes use of the cold work hardening phenomenon in the cold extrusion process to make the finished product hardness and the surface finish of the cavity. And so on.
【技术实现步骤摘要】
一种精密加工轴承
本实用涉及一种轴承,特别是涉及一种精密加工轴承。
技术介绍
目前的轴承加工装置的外形与轴承固定套的内腔的形状相同,在曲轴连杆机构下以相当高的速度对轴承固定套的坯料内腔进行冲击挤压,加工速度快的结果是一方面产量得到提高,另一方面频繁快速对轴承固定套的坯料内腔进行冲击挤压必然使冲头的温度急速上升,热膨胀必然使外形与轴承固定套的内腔的形状相同的冲头,既快速磨损又难以保证加工精度。无法加工轴承固定套的内腔成为在精确圆周截面上分布有棱或槽的特殊型腔。因此需要一种方案来解决上述问题。
