落料拉深成形工藝及模具設(shè)計 摘要:設(shè)計著重介紹了制件的成型工藝,及模具結(jié)構(gòu)設(shè)計。通過對制件的工藝分析,確定了工藝方案。并設(shè)計了一套倒裝復(fù)合模具。在設(shè)計同時利用參考資料,確定了各工作零件的尺寸。并較多的考慮了模具結(jié)構(gòu)的調(diào)整性、易更換性及模具成本。同時在模具設(shè)計內(nèi)容中融匯了沖壓模具的不同加工方法、加工工藝及裝配工藝,對初學(xué)沖壓模具模設(shè)計者有一定的參考價值。本設(shè)計從模具設(shè)計到零部件的加工工藝以及裝配工藝等進(jìn)行詳細(xì)的闡述,并應(yīng)用CAD進(jìn)行各重要零件的設(shè)計。制件是帶凸緣的筒形件,選擇合適的壓邊力是極為重要的,它具體應(yīng)在保證不起皺的前提下取最小值。卸料板在落料前兼起壓料作用。 本復(fù)合模具先由凸凹摸與落料凹模進(jìn)行落料拉深工序,后進(jìn)行沖孔工序。此外,在排樣的工作中力求板材利用率達(dá)到較高的水平。關(guān)鍵詞: 落料拉深模 復(fù)合模。 Blanking and deep drawing die design process Abstract: The design focuses on the parts of the forming process and die structure design. Parts of the process through the analysis of the process program. And design a set of flip-composite mold. At the same time, the use of reference materials in the design to determine the size of the working parts. And more to consider the restructuring of the mold, and easy to replace and the cost of mold. At the same time, the contents of the mold design stamping die in a combination of different processing methods, processing technology and assembly process, stamping die mold for novice designers have a certain reference value. The design of the parts from the mold design process and the assembly process, such as described in detail, and the application of CAD for the design of the important parts. Intending is bring the flange parts of the tube, choose a suitable blank holder force is extremely important, it should be specific to ensure that the premise of not wrinkling take the minimum. Discharge before blanking plate in the binder and role play. By the convexity of the composite mold touch with blanking blanking die for deep drawing process, after the punching process. In addition, the work of layout sheet utilization seek to reach a higher level.Key words: blanking and drawing die compound die.
