磨球斜軋工藝及軋輥實(shí)體建模設(shè)計(jì)

［摘要］：金屬產(chǎn)品和機(jī)械零件的成形工藝，可以大致分切削、焊接、鑄造、鍛造和軋制五種。對(duì)于現(xiàn)代化成形工藝，高速、高質(zhì)、省料和自動(dòng)化是發(fā)展方向。軋制成形中的斜軋技術(shù)正是具備了這些工藝特點(diǎn)而得到國(guó)內(nèi)外的重視并得已迅速發(fā)展。
螺旋孔型斜軋是斜軋工藝的一種，其特點(diǎn)是軋輥表面上帶有變高度、變螺距的型槽，盡管在軋輥的設(shè)計(jì)、制造、調(diào)整等技術(shù)方面存在較大的難度大，但利用這種斜軋技術(shù)來(lái)生產(chǎn)回轉(zhuǎn)體零件與其它成形方法相比，具有生產(chǎn)效率高、材料利用率高、軋件質(zhì)量好、設(shè)備簡(jiǎn)單、容易實(shí)現(xiàn)生產(chǎn)的機(jī)械化和自動(dòng)化等優(yōu)點(diǎn)。因此，研究螺旋孔型斜軋磨球工藝具有重要的現(xiàn)實(shí)意義。
本設(shè)計(jì)主要闡述了螺旋孔型斜軋工藝，斜軋運(yùn)動(dòng)原理，孔型設(shè)計(jì)原理及軋輥運(yùn)動(dòng)規(guī)律分析。在螺旋孔型斜軋?jiān)谠O(shè)計(jì)中，分析磨球成形的特點(diǎn)，進(jìn)而對(duì)磨球成形的軋輥孔型進(jìn)行設(shè)計(jì)計(jì)算。
本論文在分析螺旋孔型斜軋工藝的基礎(chǔ)上，設(shè)計(jì)計(jì)算了軋輥的相關(guān)參數(shù)，并利用實(shí)用的三維圖形軟件Pro/Engineer對(duì)軋輥進(jìn)行里實(shí)體建模，為軋輥的后續(xù)加工提供一定的依據(jù)。

Balls and roll skew rolling process and Solid  modeling design

Abstract：Metal products and machinery parts forming process can be broadly divided into cutting, welding, casting, forging and rolling five. Forming technology for the modern, high-speed, high quality, materials and automation is the development direction. Rolling forming the cross rolling process technology is these characteristics have received attention at home and abroad and may have been developing rapidly.
 Oblique spiral groove diagonal rolling is a rolling process, characterized by the roller surface with a variable height, variable pitch groove, despite the roller design, manufacture, adjustment, there is a big technology difficult, but Using this cross rolling techniques to produce rotary part and the other forming methods, with high efficiency, high utilization ratio, rolling good quality, simple equipment, easy production of the advantages of mechanization and automation. Therefore, the study of spiral groove diagonal rolling ball technology has important practical significance.
Described the design of the main spiral groove diagonal rolling process, cross rolling movement principle, roll pass design principles and laws of motion. In the spiral groove diagonal rolling in the design, analysis of the characteristics of ball shape, then roll on the ball shaped groove design calculations.
    This paper the analysis of helical groove diagonal rolling process based on the design and calculation of the roll of the relevant parameters, and use of utility of three-dimensional graphics software Pro / Engineer on the roll were in solid modeling of the roll of the subsequent processing to provide some basis.
Key words: Cross rolling；roll；Pass Design
