摘要
在拉伸塑料薄膜的生产过程中,滑块式膜夹具夹柄夹紧薄膜,滑块在两条间距变化的轨道上滑动,从而实现薄膜的横向拉伸.在高达 180℃的薄膜拉伸的过程中,滑块与轨道间摩擦磨损是导致产线停产的主要原因之一.为了研制适用于高温环境的更耐磨的滑块,该文研究设计了一台膜夹具滑块摩擦性能试验机.采用摩擦试验机的摩擦仿真方法来模拟滑块工况条件,通过对不同复合材料滑块的测试,得出各种复合材料滑块工况下的耐磨性能,解决了由于滑块频繁磨损导致的停线维修的问题,对降低故障率、提高生产效率有着重大意义.
Abstract
In the production process of stretching the film with a membrane clamp,the clamp handle clamps the film,and the slider on the membrane clamp slides on two tracks with varying spacing to achieve lateral stretching of the film.During the stretching process of the film at up to 180℃,friction and wear between the slider and the track are one of the main reasons for the shutdown of the production line.In order to develop more wear-resistant sliding blocks in high-temperature environments,a film fixture sliding block friction performance testing machine is designed to simulate the actual production conditions and test the wear resistance of the sliding block,in order to obtain sliding block materials that meet production requirements.It solves the problem of stop maintenance caused by frequent wear of slider,which is of great significance to reduce the failure rate and improve the production efficiency.
