【摘要】：随着市场需求的多样化及个性化,客户的订单越来越趋向多品种小批量,意味着TM公司的生产换模(型)次数变多。TM公司传统的换模(型)时间较长,浪费严重。在充分利用TM公司现有资源情况下,实施快速换模方式,可以提升生产效率,缩短生产周期,降低库存,可以提升生产能力,可以快速响应客户的需求。快速换模对TM公司的开源节流有着重要意义。选择TM公司弹簧机型为试点,通过运用“程序分析法”、“操作分析”、“动作分析法”等IE(工业工程)分析工具,运用5WHY、ECRS、PDCA等分析方法,采用“区分切换内外部作业”、“将内部作业转化成外部作业”、“缩短内部作业时间”、“缩短外部作业时间”等方法步骤,通过对弹簧机换模的工装夹具模块化、统一化、标准化,通过实施多人并行作业,对换模(型)流程实施标准化作业及实现缩短换模时间。通过对Z等产品换模流程的改善前后的分析,通过对Z等产品快速换模的验证,换模时间可以缩短40%-70%。通过实施快速换模,改变了目前弹簧机换模(型)依赖技术师傅经验、调机方法无标准的状态。快速换模是TM公司在精益生产中重点实施并优先采用的工具、方法。TM公司快速换模也是人性化的过程,快速换模目的之一是为了尊重人性,快速换模实施过程中也体现了尊重人性。TM公司对弹簧机实施快速换模方法,对弹簧行业换模(型)也会带来一定的积极的影响。
[Abstract]:With the diversification and individuation of market demand, customers' orders tend to be more and more varieties and small batches, which means that the number of production mold changes (type) of TM Company becomes more and more. The traditional mould changing time of TM Company is longer, and the waste is serious.Under the condition of making full use of the existing resources of TM Company, it is possible to improve the production efficiency, shorten the production cycle, reduce the inventory, increase the production capacity and respond quickly to the customer's demand by implementing the fast mode of changing the mould.It is very important for TM company to change the mould quickly.The spring model of TM Company is selected as a pilot. By using IE-based analysis tools, such as "program analysis", "operation analysis", "action analysis" and so on, and using the analysis methods such as 5WHYY, ECRS, PDCA, etc., it adopts the method of "distinguishing between internal and external operations".By modularizing the tooling fixture of the spring machine to change the mould, the process of "converting internal work into external operation", "shortening the internal working time" and "shortening the external working time" are unified and standardized.Through the implementation of multi-person parallel operation, standardized operation is carried out on the mould changing process and the time of changing mould is shortened.Through the analysis before and after the improvement of the changing process of Z and other products, and the verification of the rapid mold changing of Z and other products, the changing time can be shortened by 40% -70%.Through the implementation of rapid die change, the current spring machine die change (type) depends on the experience of the technical master, and the adjustment method has no standard state.Rapid mold change is a tool that TM Company implements and uses first in lean production. The method is also a humanized process. One of the purposes of rapid mold change is to respect human nature.In the process of rapid mold changing, it also reflects the respect for human nature. TM company implements the fast mode change method to spring machine, which will bring some positive influence to spring industry mould change (type).
