摘要:改革開放以來，隨著國民經濟的發(fā)展，市場對模具的需求不斷增長。近年來，模具工業(yè)一直以15%左右的增長速度快速發(fā)展，模具工業(yè)企業(yè)的所有制成分也發(fā)生了巨大的變化，除了國有專業(yè)模具廠外，集體、合資、獨資和私營也得到了快速發(fā)展，總體而言模具的各行業(yè)都得到了迅猛的發(fā)展，面臨著前所未有的機遇和挑戰(zhàn)。隨著社會發(fā)展需求的改變，模具產品正在從交貨期短、精度高、質量好、價格低的方面發(fā)展。 直管型日光燈，廣泛應用于學校、工廠、超市、家庭，是人們日常照明的一個重要組成部分。以往的日光燈燈頭都是以鋁作為主要材料，作為全球最大的鋁消費國，在當今資源緊缺的背景下，我們必須考慮鋁資源的有效、節(jié)約利用。本文以FSL佛山牌日光燈為研究對象，用10鋼燈頭來替代以往常用的鋁燈頭，對我國緩解鋁資源消耗的壓力具有一定的意義。 日光燈燈頭，其結構簡單，是一個窄凸緣圓筒。在本設計中，以佛山牌日光燈為研究對象。對加工該燈頭的模具進行了設計，主要內容包括： (1)對本論文的研究目的、意義及沖壓模具的國內外發(fā)展狀況及發(fā)展趨勢進行了敘述。 (2)對零件的加工工藝進行了分析并對相關尺寸進行了計算。主要包括：材料的選用、結構與尺寸的分析、毛坯尺寸的計算、拉深次數的確定及排樣方式的確定。 (3)模具的設計。包括落料拉深模和整形模兩副模具。主要進行了壓力機的選擇、落料拉深、整形凸凹模尺寸的計算、模架的選用、壓力機的校核、定位裝置、卸料機構的選擇與設計等。 (4)最終繪制了落料拉深模和整形模的裝配圖，同時也繪制了這兩副模具中比較重要的幾個零部件的零件圖。 (5)最后對本論文撰寫過程中存在的問題及缺陷進行了敘述，借鑒其他沖壓模具設計的經驗，給出了幾種常用的解決方法。 關鍵詞：日光燈；10鋼；落料拉深模；整形模
Abstract:Since the Reform and Opening-up, our country's national economy has been developing rapidly. The market's demand of mold also increases. In resent years, mold industry has been growing at the rate of about 15%. The ownership of mold industrial enterprises also has undergone tremendous changes. In addition to the state-owned professional mold factories, collective enterprises, joint ventures, wholly-owned enterprises and private enterprises also grow rapidly. All in all, mold industry grows fast and faces unprecedented opportunities and challenges. With the changes of the social's needs, mold products are developing toward to short delivery time, high precision, good quality, and low-price aspects. Nowadays，straight tube fluorescent lamp has been wide used in schools、factories、supermarkets、families. It is an important part of people’s daily lighting. In the past, the fluorescent lamp holder’s main component material is aluminum. As the greatest aluminum consuming counties, we must consider that use aluminum resource effectively and conservation-minded with the resource is so limited. This paper’s research object is Foshan fluorescent lamp. It will means a lot in slow down the speed of our country’s aluminum resource consumption if 10 steel cap has been used to substitute original aluminum lamp holder. Fluorescent lamp holder’s simple structure, it is a kind of narrow flanged cylinder. Foshan fluorescent lamp is the major research object in this design. The following is the main content about the processing mould design of lamp holder: (1) Narrate this paper’s research purpose、meaning and the developing situation and tendency of stamping tool at home and aboard. (2) Analysis the semi-finished product processing technique and calculate the correlative dimension. Mainly conclude that :material selection, analyzing of structure and dimensions、 calculation of the semi -finished materials size、determine of drawing times and orientation. (3) Mold design including blanking drawing die and sizing die. In this design, the main part including that: the selection of press machine、blanking drawing、calculation of plastic die and punch size、carrier selection、machine check、positioning device and the selection and design of discharge mechanism. (4) Finally, it is the drawing the blanking deep drawing mode and plastic mold assembly drawing. At the same time, draw the most important component in detail drawing of the two molds. (5) In the last place, narrate the shortage that exists in this paper when it was written. And with brought other stamping die design experience, this paper gives some common solving methods. Key words: fluorescent lamp；10 steel；blanking drawing die；sizing die
