【正文】 蓋板零件的沖壓工藝及模具設計 摘 要 沖壓生產(chǎn)是一種先進的金屬加工方法。它是利用模具和沖壓設備對板材金屬進行加工，通過沖壓生產(chǎn)可以獲得所屬要的零件形狀和尺寸。 本課題是蓋板零件的沖壓模具的設計。根據(jù)設計零件的尺寸、材料、生產(chǎn)批量等要求，分析零件的工藝性，確定沖裁工藝路線方案，從而設計一套復合模具，在保證工件的尺寸和形狀位置精度要求的同時，盡量的提 高材料的利用率和生產(chǎn)效率。 隨著計算機技術的不斷發(fā)展，采用 CAD/CAE/CAM一體化技術可以準確、快速的完成模具設計制造。 本文主要是介紹說明了蓋板零件成形 的各個工序及其模具的設計及尺寸計算，在結構設計的同時，對主要零件的設計和裝配要求技術進行了分析。 設計時考慮到模具設計合理、簡單，便于制造和修模，有利于縮短模具生產(chǎn)制造周期，降低成本。 關鍵詞： 蓋板零件；工藝路線；復合模；模具設計 Abstract Stamping production is a kind of advanced metal processing method. It is the use of mould and stamping equipment to carry on the processing of sheet metal. Through stamping production, we can get the shape and size of the parts which we need. This topic is about the design of the stamping mould for the cover parts. According to requirements of part size, material, production batch, etc. we should analyze the manufacturability of parts, and determine a medium manufacture route to design a set of pound mould. We not only should ensure the size and shape of the workpiece position accuracy requirements, but also try to improve material utilization and production efficiency. Along with the unceasing development of puter technology, it is accurate and fast to use the integration technology of CAD/CAE/CAM to plete the die designing and manufacturing. This paper mainly illustrates the flat parts forming process and the mold of each design and size calculation, the structural design of the main parts, meanwhile, the design and assembly required technologies are analyzed. When designing, we consider that the die structure should be reasonable and simple to manufacture and repair and advantageous to reduce the manufacturing cycle of die production and the costs. Keywords: cover parts。 The process route。 Composite modulus。 Mold design 目 錄 摘 要 .................................................................
