摘 要
本文主要對(duì)沖壓模具及其自動(dòng)送料機(jī)構(gòu)的設(shè)計(jì)，它的工作過程如下：在送料之前，要先用手柄抬起萬向聯(lián)結(jié)節(jié)，以便在上下輥軸之間形成空隙，將薄板料從間隙穿過，然后按下手柄壓緊入料。當(dāng)上模回程時(shí)，通過曲柄搖桿機(jī)構(gòu)中的搖桿帶動(dòng)下輥順時(shí)針旋轉(zhuǎn)，從而帶動(dòng)主動(dòng)輥和從動(dòng)輥同時(shí)旋轉(zhuǎn)完成送料工作。當(dāng)上模下行時(shí)，因?yàn)橄螺伒木壒?，輥軸停止不動(dòng)，接著就是完成沖壓的工序了。當(dāng)偏心輪再次回程，又重復(fù)上述動(dòng)作，照此循環(huán)動(dòng)作，達(dá)到間歇送料的目的。
通過對(duì)沖壓模具及其自動(dòng)送料機(jī)構(gòu)的設(shè)計(jì)，使三年所學(xué)的機(jī)械專業(yè)知識(shí)在實(shí)踐中加深了認(rèn)識(shí)，并且相當(dāng)于進(jìn)行了一次全面性的復(fù)習(xí)。
Abstract
This article mainly to the ramming mold and the feed control organization design, its work process is as follows: In front of feeding, must use the handle to lift the rotary association tubercle first, in order to forms the crevice between about stone roller, the thin sheet from the gap traversing, then presses down the handle to contract into the material. When top die return trip, through crank rocker organization in rocking bar impetus lower roll clockwise rotation, thus the impetus drive roll and the underdriven roll simultaneously revolve complete the feeding work. When top die downward, because of the lower roll reason, the stone roller stops motionless, then was completes the ramming the working procedure. When eccentric once more return trip, also duplicates the above movement, according to this the cyclic action, achieves the intermittent feeding the goal.
Through to the ramming mold and the feed control organization design, made the machinery specialized knowledge which three years institute studied to deepen the understanding in reality, and was equal in has carried on an integrity review.
