Description

一种用于刀具涂层摩擦性能测试的摩擦实验装置 技术领域
本发明涉及摩擦磨损测试技术领域，特别为一种用于刀具涂层摩擦性能测试的摩擦实验装置。
背景技术
在全球竞争的背景下，为提高生产加工效率，目前工业中对于刀具的加工通常采用非常高的切削速度，在这种高切削状态的苛刻加工条件下，会在刀具的切屑界面和切削刃周围产生极高的机械应力和温度，从而导致刀具在生产加工的过程当中产生过度磨损甚至过早失效，最终导致废品率过高。因此，为了防止这样的情况发生，我们有必要建立精确的切削过程模拟，从刀具材料、刀具几何形状和涂层等方面确定最佳的切削条件，从而维持较高的加工操作生产率，以降低废品率。
为了研究这些出现在加工界面的摩擦学现象，即机械应力问题及温度问题，研究者们其中一种研究的方法是通过实验室模拟测试，目前已经存在或已经开发了几种摩擦装置。最广为人知的装置是销盘系统，例如中国专利号为201810287951X中公开的一种小型销盘接触往复摩擦磨损试验装置，遗憾的是这类型的装置无法模拟切削中的摩擦接触条件，这是由于这种实验方法中销与盘连续重复摩擦，而切削的过程中摩擦面都是新成型面，因此采用销盘系统所模拟的摩擦条件(摩擦面初始形貌，温度，压力)与切削实际条件不一致，因此其并不能够很好地模拟切削过程的摩擦条件。此外，使用这些系统所允许的接触压力由于缺乏刚性接触，接触点的压力难以达到1GPa，因而并不适合于重载摩擦测试。
为了更好的模拟刀具切削摩擦这样的实验条件，本领域技术人员又进行了进一步的探索，例如Olsson等人提出在切削刀具后放置一个销，摩擦滑动速度和接触温度类似发生在干燥加工,但接触压力仍然很低(约15MPa)。Zemzemi等 人设计的高滑动速度(高达400m/min)下模拟更高的接触压力(高达3GPa)，显示了其提供相关摩擦系数的高效率，然而，其发明的装置非常难以管理，并且工件的制造非常长且昂贵。此外，该装置的摩擦持续时间非常有限(大约10秒)，不能进行长时间的磨损测试。Hedenqvist等人提出一种具有圆柱形几何形状的销在旋转的表面上摩擦的装置，可以产生足够的速度(几百米/分钟)，并且可以长时间测试，但无法提供足够的局部压力(约15MPa)来模拟加工过程中出现的摩擦学现象。
可见，在现有技术中，尚不存在一种既能够提供足够的接触压力同时又能够具有较长测试时间用于测试刀具切削摩擦力的装置。
发明内容
本发明的目的在于：提供一种用于刀具涂层摩擦性能测试的摩擦实验装置,其能够在保证有足够的接触压力的同时又具有较长的测试时间。

其工作原理和过程如下：
摩擦测试前，驱动转塔刀架使刀具对准柱状工件，并通过调整切削底座的位置来调整刀具与柱状工件之间的相对位置从而确定刀具切削工件深度；驱动推动装置，观测测力计显示的压力值，并根据显示的压力值调整摩擦销与柱状工件之间的压力。而后接通电源，设置第一驱动电机及第二驱动电机的旋转速度，从而分别确定柱状工件的旋转速度和刀具的进给速度。
为了更好的实施本方案,还提供如下优化方案：
