摘要:模具是大批量生產同型產品的工具，是工業(yè)生產的主要工藝裝備。模具工業(yè)是國民經濟的基礎工業(yè)。

　　　模具可保證沖壓產品的尺寸精度，使產品質量穩(wěn)定。而且在加工中不破壞產品表面。用模具生產零件可以采用冶金廠大量的廉價的軋制鋼板或鋼帶為材料，而且在生產中不需要加熱，具有生產效率高，質量好，重量輕，成本低節(jié)約能源和原材料等一系列的優(yōu)點，是其他加工方法所不能比擬的。使用模具已經成為當代工業(yè)生產的重要手段和工藝發(fā)展方向。現(xiàn)代制造工業(yè)的發(fā)展和技術水平的提高，很大程度上取決于模具工業(yè)的發(fā)展。

　　　本設計進行了沖孔、落料復合模的設計。文中簡要概述了沖壓模具目前的發(fā)展狀況和趨勢。對產品進行了詳細工藝分析和工藝方案的確定。進行了凹、凸模的閉合高度的計算并確定了模具的結構。計算并設計了本套模具上的主要零部件，如：凸模、凹模、凸凹模、凸模固定板、墊板、凹模固定板、卸料板、導板、擋料銷等。選定了合理的沖壓設備。設計中對工作零件和壓力機規(guī)格均進行了必要的校核計算。此外，本模具采用擋料銷擋料。模具的沖孔和落料凸模用固定板固定，便于調整間隙。

關鍵詞：復合模；凹模；凸模；落料

Abstract:Molds to form a mass production of industrial production facilities, is the main techniques and equipment.Mold industry is the foundation of the national economy industry.

　　　Tool to ensure accuracy of the ram of the product sizes, and make products quality.And the process of the surface of the product.Die in the production of parts of the metallurgical factory of rolled steel plates or with a material,And in production don't need, with high efficiency, quality, light weight and low cost to save energy and raw materials for a range of advantages,is other process could compare with.Use of molds has become an important means of industry and technology development. Modern industrial development and technical level, much depends on industrial development of the mold.

　　　This design has been blanking, punching, progressive die design. This paper briefly outlines the current development of stamping die situation and trends. Carried out a detailed process of product analysis and identification technology program. Stamping die design in accordance with the general steps to calculate and design the mold of this set of key components, such as: punch, die, punch retainers, plate, fixed die plate, stripper plate, guide plate, block material or marketing. Mold using standard mold, use a suitable stamping device. Design specifications of the working parts and the press were carried out the necessary checking calculation. In addition, the mold used beginning with the gauge pin gauge. Die punching and blanking punch were fixed with different fixation plate, easy to adjust the gap; punching die is fixed by the overall fixed plate. 

Key words: Gang dies; punch; die; Blanking
