南昌航空大學(xué)科技學(xué)院學(xué)士學(xué)位論文前鉸扣零件沖壓模具設(shè)計(jì)學(xué)生姓名：張志剛 班級：0681053指導(dǎo)老師：羅海泉摘要：沖壓模具是模具工業(yè)的重要組成部分，它是工業(yè)生產(chǎn)中的重要工藝裝備。沖壓模具主要包括沖裁模具、彎曲模具、拉深模具、多工位級進(jìn)模、簡單模具等等。 隨著模具工業(yè)的發(fā)展，沖壓技術(shù)在機(jī)械、航空、汽車、摩托車等行業(yè)中應(yīng)用十分廣泛，是現(xiàn)代工業(yè)生產(chǎn)的重要手段和發(fā)展方向。沖壓工藝具有生產(chǎn)率高、生產(chǎn)成本低、材料利用率高、能成形復(fù)雜零件、適合大批量生產(chǎn)等優(yōu)點(diǎn)，在某些領(lǐng)域已取代機(jī)械加工，并正逐步擴(kuò)大其工藝范圍。因此，沖壓技術(shù)對發(fā)展生產(chǎn)、增強(qiáng)效益、更新產(chǎn)品等方面具有重要作用。 本課題的生產(chǎn)實(shí)踐性非常強(qiáng)，所以在設(shè)計(jì)時要考慮實(shí)際生產(chǎn)條件。此論文的主要特點(diǎn)是通過設(shè)計(jì)一套模具使其同時滿足兩個零件的加工。首先對零件進(jìn)行沖裁和彎曲工藝分析，由于零件結(jié)構(gòu)簡單、工藝性較好,所以屬于中批量的生產(chǎn)采用單工序模比較好。然后確定工藝方案為落料、彎曲、最后成形，計(jì)算沖壓力確定模具工作部分尺寸及公差來選取模具的結(jié)構(gòu)。最后繪制落料模和彎曲模的裝配圖，并且拆繪一些主要零件圖。本課題的關(guān)鍵是合理選擇模具間隙和在彎曲時考慮彎曲件的回彈，這些因素對零件的質(zhì)量有重要影響。關(guān)鍵詞：沖壓模 彎曲模 沖壓模具標(biāo)準(zhǔn)件 工藝分析 沖壓模間隙 指導(dǎo)老師簽名：Parts of the ram up front of the die design Student name: Zhang Zhi Gang Class:0681053 Supervisor: Luo Hai QuanAbstract: Stamping die plays a very important part in die industry, it is one of the significant process equipment industry process. The principal stamping dies are blanking die, bending die, multiple station progressive die, simple die and other die, etc. With the development of mould industry, stamping technology is very applied extensively in the professions, such as machinery, aviation, automobile and motorcycle. It is the important means of modem industrial production and develops direction. The advantages of stamping technology such as productivity high, cost lowly, utilization high, become complex element and suit a large quantity of productive. In some fields, it has replaced machining, the technology scope is enlarging step by step. Therefore stamping technology has important role for developing production, strengthening benefit and update the product, etc. The production practicality of this program is very strong, so you should consider actual production condition when designing. The major characteristic of this paper is to make it at the same time satisfy the processing of two elements through designing a set of mould. First you should rush to cut and bend technology analysis for the element. Since the element structure is simple and technology better, so belong to only process mould in the production of batch. Then, the technology scheme is falling to expect, bending and becoming shape finally, and calculate the stamping force structure that determines mould working partial size and tolerance to select mould. finally the assembly drawing of stamping die and bending die, and takes apart to paint some major part drawings. The key of this program selects reasonably mould gap, and when bending, consider the spring back of curved, these factors have influence for the quality of element.Keywords: stamping die bending die standard units of stamping die technical analysis clearance of punching mould Signature of supervisor:
