摘要
为了提高小锯片的生产效率、产品合格率和产品质量,本文把热压工艺应用于烧结小锯片的生产,通过对烧结过程中的温度与压力的控制,即升温时间3min,保温时间5min;初压设定在5MPa,终点压力设定在12MPa。在该工艺下生产的小锯片的使用寿命比井式炉烧结的小锯片延长50%,硬度偏差在±10度(HRB)以内,产品合格率达到98%以上。该工艺下生产的小锯片经国家磨料磨具质量监督检验中心检测,符合技术指标要求。解决了金刚石小锯片生产效率低、硬度不均匀、质量不稳定等问题。取得了较好的效果,提高了产品质量并使质量稳定,同时降低了生产成本,获得了可观的经济效益。
This text introduced the sintering technology of small diameter saw blade by way of controlling the temperature and the pressure during the sintering, which means the heating up time is 3min,and the heat preservation time is 5min,initial pressure is 5MPa,and the end up pressure is 12MPa. The result indicated that the life span of the small saw blade has prolonged by 50%. The hardness deviation ranged in 10HRB,the reject rate was reduced to 2%. This method has overcome the problems of low efficiency, unhomogeneous hardness and unstable quality. This method has raised the work efficiency and reduce the production cost of the saw blade.
