20kg鋁錠鑄機傳動及輸送系統(tǒng)改造設計

摘　　要

鋁作為一種重要的金屬材料，被廣泛應用于航空航天，集裝箱，地鐵等各種工業(yè)領域。改進鋁錠的質量，生產出優(yōu)質鋁材，從而服務于我國的現(xiàn)代化建設，是鋁工業(yè)的任務之一。現(xiàn)有的鋁錠鑄機的傳動系統(tǒng)尤其是輸送系統(tǒng)的不平穩(wěn)性，導致了鋁錠表面形成波紋，造成表面質量的不足。本設計就是要通過對鋁錠連續(xù)鑄造機組進行局部改進，從而達到提高鋁錠表面質量的目的。如果能夠將鑄機輸送鏈的運行平穩(wěn)性極大的提高，那么鋁錠的外觀質量就可以得到改善。設計思路是通過對輸送鏈運行不平穩(wěn)性成因的探究而想出改進其平穩(wěn)性的的眾多方案。然后通過綜合比較（包括經濟角度，現(xiàn)實角度以及技術層面的比較），從中選出較理想的方案——采用鏈傳動對輸送鏈進行補償。該方案主要就改進鏈傳動和輸送鏈的尺寸參數(shù)展開，同時對鏈傳動的鏈條以及大小鏈輪進行逐一設計，并計算出輸送鏈的相關尺寸。最后得到改進后的輸送鏈以及傳動鏈的尺寸參數(shù)。

Abstract

The aluminum is a kind of important metal material, is been widely used in a variety of industrial fields, for example in the aerospace, containers producing, MTR. and so on. Improving the quantity of the aluminum tablet, and producing enough high-quality aluminum material, to be serve for the modernization  construction of our country, is one of tasks of the aluminum industry. The transmission system of aluminum table casting machine particular it’s transport system can’t move steadily that lead to that  on the surface of the aluminum table ripples forms and result in the shortage of the surface quantity. The design is to attain the purpose of improve the quantity of aluminum tables by improving some part of machine to cast aluminum table continuously. If we can raise the movement steady of the transport train of the casting machine greatly, the external appearance quantity of the aluminum tablet will be improved. The design idea is to figure out numerous project of improving chain’s movement steady by researching the reason why the chain can’t circulate steadily. Then I adopt comprehensive comparison (including economic perspective , the more realistic perspective and the technical level) to select the preferred project ---adopting transmission chain spreads to move to carry on the repair towards the transport chain. This project is mainly carried out by improving the size parameter of transmission chain and transport chain, at the same time design the transmission chain and compute related size of the transport chain. Obain the feater size parameter of transmission chain and transport chain finally after getting an improvement.
