摘 要

隨著科技的進(jìn)步，人們對(duì)棒材的需求量越來(lái)越大、對(duì)其精度要求也越來(lái)越高，以前人們采用平行輥矯直機(jī)矯直管、棒等圓形斷面條材，圓材在矯直過(guò)程中容易產(chǎn)生自轉(zhuǎn)現(xiàn)象，并且只能矯直圓材垂直于輥軸的縱向剖面上的彎曲。在這種情況下斜二輥矯直機(jī)的問(wèn)世解決了以前平行輥矯直機(jī)所解決不了的棒材、管材的矯直問(wèn)題，在這種情況下，我們對(duì)二輥滾光矯直機(jī)進(jìn)行設(shè)計(jì)。
本文重點(diǎn)對(duì)鋼材矯直工藝及工作原理，斜輥矯直機(jī)的工作原理、特點(diǎn)、結(jié)構(gòu)等進(jìn)行了介紹，同時(shí)對(duì)二輥棒材矯直機(jī)力能參數(shù)的計(jì)算進(jìn)行了分析，提出了本次設(shè)計(jì)二輥棒材矯直機(jī)的基本思路。矯直機(jī)的機(jī)架、機(jī)座、傳動(dòng)等部分設(shè)計(jì)不屬于本次設(shè)計(jì)的重點(diǎn)，所以在這里只是作了簡(jiǎn)單的介紹，但是由于時(shí)間比較倉(cāng)促，本文對(duì)矯直機(jī)的液壓壓下裝置、矯直機(jī)的安裝與維護(hù)沒(méi)有做出詳盡的介紹，限于本人的水平，文中有誤漏之出，還請(qǐng)批評(píng)指正。

ABSTRACT
With the advancement of technology, people's growing demand for the bar, its accuracy is also getting higher and higher, before people parallel roller leveler straightening tubes, rods and other circular cross-section of the build, round-wood in hand Direct the process of rotation is easy to produce, and only straightening roundwood roll axis perpendicular to the longitudinal section on the bend. In this case the ramp roll straightening machine resolved before the advent of parallel roll straightening machine can not be resolved by the bar, pipe straightening of the problem, in this case, we design roll on the roller-straightening machine.
The steel straightening process and working principle, ramps roll straightening machine works, characteristics, such as the structure was introduced, while two of the roll bar straightening machine can be calculated parameters of an analysis of the proposed The design of the roll bar leveler of the basic ideas. Straightening machine rack, engine, transmission and other parts of the design are not the focus of this design, so here is a brief introduction, but because of the time hasty comparison, the paper leveler of the hydraulic pressure devices, Straightening machine installation and maintenance have not made detailed introduction, I am limited to the level of error in the text of a leak, also invited criticism correction.
Key words: bars；Straightening process；the two roll bar straightening machine；straightening of the power parameters
