摘要:改革开放以来,随着国民经济的发展,市场对模具的需求不断增长。近年来,模具工业一直以15%左右的增长速度快速发展,模具工业企业的所有制成分也发生了巨大的变化,除了国有专业模具厂外,集体、合资、独资和私营也得到了快速发展,总体而言模具的各行业都得到了迅猛的发展,面临着前所未有的机遇和挑战。随着社会发展需求的改变,模具产品正在从交货期短、精度高、质量好、价格低的方面发展。

   直管型日光灯,广泛应用于学校、工厂、超市、家庭,是人们日常照明的一个重要组成部分。以往的日光灯灯头都是以铝作为主要材料,作为全球最大的铝消费国,在当今资源紧缺的背景下,我们必须考虑铝资源的有效、节约利用。本文以FSL佛山牌日光灯为研究对象,用10钢灯头来替代以往常用的铝灯头,对我国缓解铝资源消耗的压力具有一定的意义。

   日光灯灯头,其结构简单,是一个窄凸缘圆筒。在本设计中,以佛山牌日光灯为研究对象。对加工该灯头的模具进行了设计,主要内容包括:

   (1)对本论文的研究目的、意义及冲压模具的国内外发展状况及发展趋势进行了叙述。

   (2)对零件的加工工艺进行了分析并对相关尺寸进行了计算。主要包括:材料的选用、结构与尺寸的分析、毛坯尺寸的计算、拉深次数的确定及排样方式的确定。

   (3)模具的设计。包括落料拉深模和整形模两副模具。主要进行了压力机的选择、落料拉深、整形凸凹模尺寸的计算、模架的选用、压力机的校核、定位装置、卸料机构的选择与设计等。

   (4)最终绘制了落料拉深模和整形模的装配图,同时也绘制了这两副模具中比较重要的几个零部件的零件图。

   (5)最后对本论文撰写过程中存在的问题及缺陷进行了叙述,借鉴其他冲压模具设计的经验,给出了几种常用的解决方法。

关键词:日光灯;10钢;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
