導(dǎo)板·導(dǎo)盤——淺析二輥斜軋穿孔導(dǎo)圍工具與變形過程

Guide Shoe·Guide Disc—A Primary Discussion on Guiding Tools for 2-roll Rotary Piercing Process and Relevant Deformation Process

摘要: 介紹了二輥斜軋穿孔變形區(qū)的組成以及導(dǎo)圍工具的發(fā)展歷程；分析了導(dǎo)板、導(dǎo)盤在穿孔變形過程中軋件與工具的接觸順序；敘述了導(dǎo)板、導(dǎo)盤在封閉變形區(qū)時各自的特點，以及在穿軋試驗機上進(jìn)行的關(guān)于導(dǎo)圍工具對穿孔效率影響的試驗情況；結(jié)合導(dǎo)板、導(dǎo)盤兩者的優(yōu)點，提出了一個關(guān)于改造導(dǎo)板安裝、使用方式的設(shè)想。

Abstract: Described in the article are composition of the 2-roll rotary piercing deformation zones, and the development history of the guiding tools.Analyzed is the sequence of contact between the workpiece and the operational tool.i.e., the guide shoe or the guide disc during piercing deformation process.Elaborated are the separate characteristics of the guide shoe and the guide disc in the closed deformation zone, and the result of the test as performed with the piercing testmachine for the purpose of identifying the effect by the guiding tools on piercing efficiency. Taking the advantages of both the guide shoe and the guide disc into consideration, an idea for improving installation and operation processes for the guide shoe is put forward.
