計(jì)算與說(shuō)明 結(jié)果 第1章 前言 1.1沖壓的概念、特點(diǎn)及應(yīng)用 沖壓是利用安裝在沖壓設(shè)備（主要是壓力機(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（俗稱(chēng)沖壓或沖壓件）的一種壓力加工方法。沖壓通常是在常溫下對(duì)材料進(jìn)行冷變形加工，且主要采用板料來(lái)加工成所需零件，所以也叫冷沖壓或板料沖壓。沖壓是材料壓力加工或塑性加工的主要方法之一，隸屬于材料成型工程術(shù)。 沖壓所使用的模具稱(chēng)為沖壓模具，簡(jiǎn)稱(chēng)沖模。沖模是將材料（金屬或非金屬）批量加工成所需沖件的專(zhuān)用工具。沖模在沖壓中至關(guān)重要，沒(méi)有符合要求的沖模，批量沖壓生產(chǎn)就難以進(jìn)行；沒(méi)有先進(jìn)的沖模，先進(jìn)的沖壓工藝就無(wú)法實(shí)現(xiàn)。沖壓工藝與模具、沖壓設(shè)備和沖壓材料構(gòu)成沖壓加工的三要素，只有它們相互結(jié)合才能得出沖壓件。 與機(jī)械加工及塑性加工的其它方法相比，沖壓加工無(wú)論在技術(shù)方面還是經(jīng)濟(jì)方面都具有許多獨(dú)特的優(yōu)點(diǎn)。主要表現(xiàn)如下： （1）沖壓加工的生產(chǎn)效率高，且操作方便，易于實(shí)現(xiàn)機(jī)械化與自動(dòng)化； （2）沖壓時(shí)由于模具保證了沖壓件的尺寸與形狀精度，且一般不破壞沖壓件的表面質(zhì)量,而模具的壽命一般較長(zhǎng),所以沖壓的質(zhì)量穩(wěn)定,互換性好等特征； （3）沖壓可加工出尺寸范圍較大、形狀較復(fù)雜的零件，如小到鐘表的秒表，大到汽車(chē)縱梁、覆蓋件等，加上沖壓時(shí)材料的冷變形硬化效應(yīng)，沖壓的強(qiáng)度和剛度均較高； 設(shè)計(jì)項(xiàng)目 計(jì)算與說(shuō)明 結(jié)果 （4）沖壓一般沒(méi)有切屑碎料生成，材料的消耗較少，且不需其它加熱設(shè)備，因而是一種省料，節(jié)能的加工方法，沖壓件的成本較低； 1.2 沖壓的基本工序及模具 由于沖壓加工的零件種類(lèi)繁多，各類(lèi)零件的形狀、尺寸和精度要求又各不相同，因而生產(chǎn)中采用的沖壓工藝方法也是多種多樣的。概括起來(lái)，可分為分離工序和成形工序兩大類(lèi)；分離工序是指使坯料沿一定的輪廓線(xiàn)分離而獲得一定形狀、尺寸和斷面質(zhì)量的沖壓（俗稱(chēng)沖裁件）的工序；成形工序是指使坯料在不破裂的條件下產(chǎn)生塑性變形而獲得一定形狀和尺寸的沖壓件的工序。按基本變形方式不同又可分為沖裁、彎曲、拉深和成形四種基本工序，每種基本工序還包含有多種單一工序。 在實(shí)際生產(chǎn)中，當(dāng)沖壓件的生產(chǎn)批量較大、尺寸較少而公差要求較小時(shí)，若用分散的單一工序來(lái)沖壓是不經(jīng)濟(jì)甚至難于達(dá)到要求。這時(shí)在工藝上多采用集中的方案，即把兩種或兩種以上的單一工序集中在一副模具內(nèi)完成，稱(chēng)為組合的方法不同，又可將其分為復(fù)合、級(jí)進(jìn)和復(fù)合-級(jí)進(jìn)三種組合方式。 復(fù)合沖壓——在壓力機(jī)的一次工作行程中，在模具的同一工位上同時(shí)完成兩種或兩種以上不同單一工序的一種組合方法式。 級(jí)進(jìn)沖壓——在壓力機(jī)上的一次工作行程中，按照一定的順序在同一模具的不同工位上完面兩種或兩種以上不同單一工序的一種組合方式。復(fù)合-級(jí)進(jìn)——在一副沖模上包含復(fù)合和級(jí)進(jìn)兩種方式的組合工序。 沖模的結(jié)構(gòu)類(lèi)型也很多。通常按工序性質(zhì)可分為沖裁模、彎曲模、拉深模和成形模等；按工序的組合方式可分為單工序模、復(fù)合模和級(jí)進(jìn)模等。
