錐形輥穿孔機(jī)導(dǎo)板的優(yōu)化設(shè)計(jì)

Optimized Design of Cone Type Piercer Guide Shoe

摘要: 結(jié)合某公司穿孔機(jī)實(shí)際情況，從軋輥和導(dǎo)板的空間幾何入手，重點(diǎn)介紹了導(dǎo)板設(shè)計(jì)的數(shù)學(xué)方法。通過計(jì)算導(dǎo)板變形區(qū)長(zhǎng)度、導(dǎo)板出入口斜面斜角及導(dǎo)板寬度等基本參數(shù)，認(rèn)為由數(shù)學(xué)公式法確定的導(dǎo)板基本尺寸比經(jīng)驗(yàn)法更科學(xué)，導(dǎo)板孔型封閉性更好，在生產(chǎn)薄壁管時(shí)能有效防止鏈帶或破尾。

Abstract: Based on relevant actual circumstances of the piercing mill located a certain domestic company, and starting with the space geometry of the roll and the guide shoe, the mathematic method for designing the guide shoe is mainly described.The basic parameters such as the deformation zone length, the inlet obliquity and the oblique angle, and the width of the guide shoe are calculated.As a result, it is identified that the basic dimensions as determined with the mathematic formula are more scientific than those as obtained with the empiric method.Such basic dimensions ensures a better closure of the guide shoe groove, which can prevent chain band or tail end breaking in case of production of light-wall pipes.
