盒形件沖壓工藝分析及復合模具設計

摘  要

該套模具制造簡單,但需要多套模具,效率低、流程路線太長,過程分離,更難保證零件的精度和技術要求,并且過程自動化程度不高,生產成本也非常高,已經不能滿足現代機械加工的需求。所以為了解決這種問題,針對沖壓工藝和矩形盒拉深過程,首先介紹了盒形件冷沖壓成形過程，通過對盒形件的批量生產、零件質量、零件結構以及使用要求的分析、研究，按照不降低使用性能為前提，等設計出三種不同的沖壓工藝方案并且分析和比較的形成過程包括單一過程,復雜的過程和持續(xù)的過程也就是我們常說的單工序、復合工序和連續(xù)工序,最終確定用一套復合模完成落料、拉深、沖底面矩形孔，翻邊的工序過程。精加工沖壓方法,力的計算,模具尺寸和公差,和設計模具。一份詳細的零件清單和所需的模具,并給出一個合理的裝配圖。給未來的設計提供了一個參考，借鑒執(zhí)筆的成效。

Abstract

The mold manufacturing is simple, but need more sets of molds, low efficiency, process route is too long, the separation process, more difficult to guarantee precision parts and technology, and process automation degree is not high, the production cost is also very high, has been unable to meet the demand of modern machining. So in order to solve this problem, the stamping process and the deep drawing process of rectangular box, introduced the process of cold stamping parts box.So in order to solve this problem, in view of the stamping process and the rectangular box deep drawing process, cold stamping process, the box parts are introduced through the quality of mass production of box parts, parts, parts structure as well as the use requirement analysis the box shaped parts of the mass production, quality components, parts structure and analysis, requirements of the study, in accordance with the use of performance is not reduced, will determine its stamping parts, three stamping process analysis and comparison of different process involves the formation of a single process, complex process and continuous process is what we often say that the single processes, complex processes and continuous processes, determined by a set of compound die blanking, drawing, punching bottom moment face process. Fine punching method, calculation of the force, mold dimensions and tolerances, and die design. A detailed list of parts and tooling required, and gives a reasonable assembly. By making full use of modern mould manufacturing technology to the traditional mechanical parts for structural improvement, optimization design, optimization of process method can greatly improve the production efficiency, this method has a certain reference value to the similar products.Provide a reference for the future design, drawing pen effect. Hope this design can be a template for future design data, also contribute to the mechanical industry in our country, makes our country mechanical industry more and more developed, the development of getting better and better.

Keywords: Rectangular box; tensile; compound die; die design
