【正文】 寸，所以凸模的尺寸L=15+15+15=45mm.遼寧石油化工大學(xué)職業(yè)技術(shù)學(xué)院17凸模材料 W18Cr4V圖 沖孔凸模 選擇堅(jiān)固件及定位零件(1) 螺釘規(guī)格的選用: 根據(jù)設(shè)計(jì)要求模具上部分的螺釘可選用 M8,在根據(jù)實(shí)際要求 ,查標(biāo)準(zhǔn)選用 GB /T M855,這里要 4 個,模具下部分的螺釘根據(jù)設(shè)計(jì)選用 M8,查得標(biāo)準(zhǔn)為 GB /T 702022 這里要 4 45 鋼.(2) 圓柱銷規(guī)格的選用:銷釘?shù)墓Q直徑可取與螺釘大徑相同或小一個規(guī)格, 根據(jù)定位方式及坯料的形狀與尺寸,選用合適的標(biāo)準(zhǔn)定位零件.模具上部分的圓柱銷根據(jù)標(biāo)準(zhǔn)選用 GB/T 1192022 A850, 選取材料為 45 鋼.模具下部分的圓柱銷根據(jù)標(biāo)準(zhǔn)選用 GB/T 1192022 A845，取材料為 45 鋼。而且大大提高了動手的能力，使我充分體會到了在創(chuàng)造過程中探索的艱難和成功時的喜悅。本人授權(quán)　　 　 　 大學(xué)可以將本學(xué)位論文的全部或部分內(nèi)容編入有關(guān)數(shù)據(jù)庫進(jìn)行檢索，可以采用影印、縮印或掃描等復(fù)制手段保存和匯編本學(xué)位論文。除了文中特別加以標(biāo)注引用的內(nèi)容外，本論文不包含任何其他個人或集體已經(jīng)發(fā)表或撰寫的成果作品。通過這次畢業(yè)設(shè)計(jì)，我才明白學(xué)習(xí)是一個長期積累的過程，在以后的工作、生活中都應(yīng)該不斷的學(xué)習(xí)，努力提高自己知識和綜合素質(zhì)。同時,硅鋼中的硅使材料的電阻率增大,也起到減小渦流的作用. 遼寧石油化工大學(xué)職業(yè)技術(shù)學(xué)院103 沖壓模具總體結(jié)構(gòu)設(shè)計(jì) 模具類型根據(jù)零件的沖裁工藝方案,采用倒裝式復(fù)合沖裁模. 操作與定位方式零件中批量生產(chǎn),安排生產(chǎn)可采用手工送料方式能夠達(dá)到批量生產(chǎn),且能降低模具成本,，厚度較高，保證孔的精度及較好的定位，宜采用導(dǎo)料板導(dǎo)向，導(dǎo)正銷導(dǎo)正，為了提高材料利用率采用始用擋料銷和固定擋料銷。沖壓生產(chǎn)為適應(yīng)這一新的要求，開發(fā)了多種適合不同批量生產(chǎn)的工藝、設(shè)備和模具。模具制造技術(shù)現(xiàn)代化是模具工業(yè)發(fā)展的基礎(chǔ)。工作時，坯料在下模面上通過定位零件定位，壓力機(jī)滑塊帶動上模下壓，在模具工作零件（即凸模、凹模）的作用下坯料便產(chǎn)生分離或塑性變形，從而獲得所需形狀與尺寸的沖件。 沖壓地、在現(xiàn)代工業(yè)生產(chǎn)中，尤其是大批量生產(chǎn)中應(yīng)用十分廣泛。 Products rough start calculating the size is calculated at a convenient but does not affect mold forming on the premise familiar to simplify the model. The paper also forming part of the stamping dies and other relevant parts of the principle of choice and select the method described. Stamping parts from the design of the first stamping on the production process to be designed to cover iron of chipfor stamping process of analysis and calculation and then calculated on the basis of analysis and see stamping design information related to determine the programme stamping process, and on this basis The process of determining the relationship, and then entered the concrete structure of the die design. On this basis, all of the major parts stamping die design and size, the large number of reference during the relevant information with the press and read all kinds of stamping Manual and calculated to determine the specific mold of the structure and Size, by the calculation and constant changes in the careful guidance of teachers under the guidance of patient care and continuously repeated changes to draw the final 1 assembly and 3 parts map. Through this I graduated from design to understand and master the many practical things with my internship in the production of which would like to see some of the things, with some of their own harvest. In this special thanks to college, school teachers for giving me this opportunity and the careful guidance.
