Abstract

本实用新型公开了一种改进的辗扩圆锥滚子轴承外圈用模具。该改进的辗扩圆锥滚子轴承外圈用模具包括扩轮、扩轴和挡料板,所述扩轮与工件相接触的面为L形槽,即扩轮与工件的两个端面相接触。由于扩轮与工件相接触的面为L形槽,改变了扩轮、扩轴和挡料板的组合方式,形状简单,工件对扩轮接触面的磨损小,使其加工精度与使用寿命提升,也方便维修。

Description

改进的辗扩圆锥滚子轴承外圈用模具
技术领域
[0001] 本实用新型涉及机械加工技术领域,特别是涉及一种改进的加工圆锥滚子轴承外圈的扩轮。
背景技术
[0002] 圆锥滚动轴承具有高承载能力和高可靠性,广泛用于机械、汽车、船舶等重载传动轴的支承。圆锥滚动轴承有圆锥形内圈和外圈滚道,圆锥滚子排列在两者之间,适合承受复合(径向与轴向)负荷。圆锥滚动轴承的套圈是重要的承载部件,对轴承的性能有着重要的影响。圆锥滚动轴承的套圈大都采用传统的热锻造加工工艺,这种工艺存在很多缺点,影响轴承的性能。笔者讨论了一种冷辗扩成形工艺,能有效地节省材料和能耗,提高套圈精度,从而提高轴承的使用寿命。
[0003] 轴承行业辗扩圆锥滚子轴承外圈所用的传统模具由扩轮、扩轴和挡料板组成。扩轮上开有凹形槽,通过扩轴与扩轮的内外挤压,使工件在凹形槽内成型。传统模具扩轮上与工件接触的面为凹形槽,与工件的三个端面相接触,形状复杂,不便维修,大批量生产时扩轮失效损坏,造成加工工件精度不达标,扩轮只能报废处理,浪费生产资源。
发明内容
[0004] 本实用新型的目的是设计一种结构简单、加工精度高、便于维修的辗扩圆锥滚子轴承外圈模具。
[0005] 本实用新型的目的是通过以下技术方案实现的,该辗扩圆锥滚子轴承外圈用模具包括扩轮、扩轴和挡料板,所述扩轮与工件相接触的面为L形槽,即扩轮与工件的两个端面相接触。
[0006] 本实用新型的有益效果:
[0007] 由于扩轮与工件相接触的面为L形槽,改变了扩轮、扩轴和挡料板的组合方式,扩轮与工件的两个端面相接触,形状简单,工件对扩轮接触面的磨损小,使其加工精度与使用寿命提升,也方便维修。
附图说明
[0008] 下面结合附图详细说明本实用新型的实施例
[0009] 图1为本实用新型的示意图
[0010] 图2为改进前辗扩圆锥滚子轴承外圈用模具
[0011] 图中:1、扩轮2、扩轴3、工件4、档料板5、L形槽6、凹形槽
具体实施方式
[0012] 如图1所示,该辗扩圆锥滚子轴承外囤用模具包括扩轮1、扩轴2和挡料板4,工件3位于扩轮I与扩轴2之间,扩轮I与工件3相接触的面为“L”型槽5,即扩轮I与工件3的两个端面相接触,通过扩轴2与扩轮I的内外挤压,使工件3在L型槽5内成型。
[0013] 图2示出了改进前辗扩圆锥滚子轴承外圈用模具扩轮I的凹形槽6。
