950熱軋帶鋼生產(chǎn)線飛剪機(jī)設(shè)備能力校核及部件設(shè)計(jì)（本科畢業(yè)論文設(shè)計(jì)）

摘    要

目前在生產(chǎn)實(shí)際中使用的飛剪機(jī)種類繁多，但由于它們各自具有自身的特點(diǎn)，從而也適用于各種不同的工況場(chǎng)合。在連續(xù)式軋制生產(chǎn)作業(yè)線上，用來剪切軋件頭尾或切分卷時(shí)，就大量使用了轉(zhuǎn)鼓式飛剪。本課題中所研究的轉(zhuǎn)鼓式飛剪正是用在川威熱連軋機(jī)上進(jìn)行軋件頭尾剪切和分卷剪切的重要輔助設(shè)備，它的任務(wù)是將運(yùn)行著的軋機(jī)按工藝要求的尺寸橫向剪斷。用飛剪進(jìn)行運(yùn)動(dòng)著的軋件的剪切始于十九世紀(jì)末期，人們?cè)趯?shí)踐的基礎(chǔ)上不斷進(jìn)行改進(jìn)和完善，使飛剪的性能得到了很大的提高。
本文通過對(duì)轉(zhuǎn)鼓式飛剪機(jī)的力能參數(shù)，主要零部件的校核以及在使用過程的注意事項(xiàng)三方面的簡(jiǎn)要闡述，為以后在實(shí)際生產(chǎn)中改進(jìn)飛剪機(jī)的性能提供了相對(duì)比較完整的理論依據(jù)和方法。飛剪機(jī)隨著電氣與其它技術(shù)的發(fā)展，盡管其結(jié)構(gòu)已從原來十分復(fù)雜的機(jī)械而變得相對(duì)簡(jiǎn)單，但力能參數(shù)的計(jì)算是不會(huì)改變的，本文在大量實(shí)測(cè)、分析計(jì)算的基礎(chǔ)上，對(duì)飛剪機(jī)的研究計(jì)算提出一些簡(jiǎn)潔實(shí)用的計(jì)算方法。這無論是對(duì)于新飛剪機(jī)的設(shè)計(jì)，還是對(duì)現(xiàn)有飛剪機(jī)的分析計(jì)算，都具有實(shí)際意義。

ABSTRACT

In actual production use of a wide range of flying shear, but they each have their own characteristics, thus applicable to a variety of conditions occasions. In continuous rolling production line, to shear workpiece incurable or cut volume, the large-scale use of a rotating drum flying shear. The issue of the study to drum flying shear Chuanwei is used in hot strip mill on the workpiece and incurable shear-shear volume of Auxiliary equipment, it will be the task of running the mill by the technological requirements of the transverse shear size, Shear used to the exercise of the rolling shear began in the late 19th Century, in practice on the basis of constant improvement, so that the flying shear performance greatly improved.
Based on the rotating drum flying shear strength parameters, Check the major parts of the process and the use of the three issues to the attention of a brief exposition for the future in production to improve the flying shear properties provide a relatively complete theory and method. With scissors electrical and other technical development, though its structure from the original complex machinery has become relatively simple, But parameters of the calculation is not going to change, the paper in a large number of measurement, analysis and calculation on the basis of right flying shear terms of some simple practical method of calculation. This is the new scissors design, or the existing flying shear analysis, have practical significance.

Key words： Rotating drum flying shear, Force Parameters, Check parts
