最近几年,由于工具产量的显著增长,工具制造中广泛应用的钢材牌号的部份变更,以及在生产中新型的科研和工艺成果的引进推广,在金属切削刀具热处理领域里发生了极其显著的变化。产量的显著增长,使得工具制造厂更广泛地采用各种自动和半自动工具热处理流水线。现在,大型工具制造厂生产的工具有70—80％是用机械化设备进行热处理的。自动化和机械化水平也随之发生了相当大的变化。第二代半自动和自动流水线得到了日益广泛的应用:工具从一个槽到另一个槽的运输,用自动化操作代替了过去的链条传动和杠杆传动,按特定的循环流水作业程序进行工作,并能够保证严格遵守工具热处理或化学
In recent years, due to the significant increase of tool production, the partial change of steel grades widely used in tool manufacturing and the introduction and promotion of new type of scientific research and process achievements in the production, extremely remarkable results have occurred in the field of heat treatment of metal cutting tools Variety. Significant increases in production have led toolmakers to adopt a wider variety of automatic and semiautomatic tool heat treatment lines. Now, 70-80% of the tools made by large tooling factories are heat-treated with mechanized equipment. There has also been a considerable change in the level of automation and mechanization. The second generation of semi-automatic and automatic assembly lines is gaining more and more widespread use: the transport of tools from one tank to another, the automation of operations replacing the chain and lever transmissions, the operation of a specific cycle of operation and the ability to Ensure strict adherence to tool heat treatment or chemistry
