時間:2019-05-31 23:27來源:畢業論文
比較成型的過程主要分為單一過程,復雜的過程和持續的過程,也就是我們經常說的單工序,復合工序和連續工序,并最終由一個復雜的模具完成落料、拉深和沖裁底面的矩形孔和翻邊的過程

摘要:對于這個零件,一般的模具雖然制造很簡單,但是需要設計多套模具, 流程路線太長,效率低,分離過程中,很難保證零件的精度和技術要求,以及流程的自動化程度不高,生產成本相對較高,它已經無法滿足現代加工的需要。為了解決客觀問題,就方盒形托盤工件沖壓工藝過程和拉深的過程中,首先介紹了盒型件冷沖壓工藝成型后,通過方盒形零件的生產、零件的質量,零件的結構以及需求進行分析研究,以不減少使用性能為前提設計三種不同的沖壓工藝方案并進行分析。比較成型的過程主要分為單一過程,復雜的過程和持續的過程,也就是我們經常說的單工序,復合工序和連續工序,并最終由一個復雜的模具完成落料、拉深和沖裁底面的矩形孔和翻邊的過程。完成沖壓方法,計算模具的尺寸,公差及模具設計。通過CAD繪制出一份較為完整合理的裝配以及向配套的零件圖。35824

Mold Design of Box-type Tray Work Piece
Abstract: For this work piece, although the general mold is simple, it requires multiple sets of molds, low efficiency, process route is too long, the separation process, more difficult to ensure the precision and technical requirements of parts, and the degree of automation of the process is not high, while the cost of production is relatively high, it has been unable to meet the needs of modern machining. So in order to solve the objective problem, the process of stamping process for drawing and box-member, I firstly introduced in a rectangular box of cold stamping process after molding, through the box-shaped pieces of production, quality parts, parts of the structure as well as requirements analysis, research, so as not to reduce the use of performance as a precondition to design three different stamping process plan and analyze each other. Process is the formation of mainly single process, complicated process and continuous process, we often say that is single step, complex processes and continuous processes, and ultimately determined by a complex mold to complete blanking, drawing, red bottom surface of the rectangular hole and flanging processes. Finishing stamping method, computing power, die size, tolerance and mold design. A detailed parts list and meet the production requirements of the mold, and a more reasonable assembly drawing would be given.
