摘 要
沖壓模具，是在冷沖壓加工中，將材料（金屬或非金屬）加工成零件（或半成品）的一種特殊工藝裝備，稱為冷沖壓模具（俗稱冷沖模）。沖壓，是在室溫下，利用安裝在壓力機(jī)上的模具對(duì)材料施加壓力，使其產(chǎn)生分離或塑性變形，從而獲得所需零件的一種壓力加工方法。在本文中，通過(guò)分析支架的結(jié)構(gòu)特點(diǎn)和成型工藝，根據(jù)工件的的形狀、尺寸及材料等因素，計(jì)算出沖壓力大小以及確定沖壓中心，從而選取了所適用的壓力機(jī)及模柄，并以此為基礎(chǔ)選擇標(biāo)準(zhǔn)后側(cè)導(dǎo)柱模架，根據(jù)模架尺寸進(jìn)一步推算出模具中沖孔凸凹模、彎曲凸凹模、墊板等零件尺寸。在完成所有計(jì)算類之后，利用三維造型軟件Proe以及計(jì)算機(jī)輔助設(shè)計(jì)軟件CAD，分別繪制出模具各個(gè)零件并及整體裝配圖，并對(duì)模具結(jié)構(gòu)中一些重點(diǎn)組件進(jìn)行具體的描述及驗(yàn)算，驗(yàn)算不合格的零件進(jìn)行更換調(diào)試，最后將成品模具轉(zhuǎn)化到圖紙上，進(jìn)行進(jìn)一步的驗(yàn)算改正及研究，最終確定出各板件所用材料，以及總結(jié)所遇到的問(wèn)題及建議解決方法。

ABSTRACT
Stamping die, is in the cold stamping process, the material (metal or non-metallic) processed into parts (or semi-finished products) of a special process equipment, known as cold stamping die (commonly known as cold die). Stamping is a method of applying pressure to a material at a room temperature by means of a mold mounted on a press to produce a pressure or a plastic deformation to obtain a desired pressure machining method. In this paper, by analyzing the structural characteristics and forming process of the stent, the punching force is calculated according to the shape, size and material of the workpiece, and the punching center is determined, and the applicable press and die are selected. This is based on the selection of the standard rear guide post mold, according to the size of the mold to further calculate the punching punch mold, bending convex die, pad and other parts size. After the completion of all the calculation class, the use of three-dimensional modeling software Proe and computer-aided design software CAD, respectively, to draw out the mold parts and the overall assembly diagram, and some of the key components of the mold structure of a specific description and check, check the unqualified Parts to replace the commissioning, and finally the finished mold into the drawings, to further verify the correction and research, and ultimately determine the materials used in the board, and summed up the problems encountered and suggested solutions.
