摘 要

硬質(zhì)合金材料的刀具因其具有硬度高，紅硬性好﹑耐磨性好和使用壽命長(zhǎng)等優(yōu)點(diǎn)而在實(shí)際生產(chǎn)中得到廣泛的應(yīng)用。硬質(zhì)合金可轉(zhuǎn)位刀具與普通硬質(zhì)合金焊接刀具相比更具有切削性能好,生產(chǎn)效率高,刀具壽命長(zhǎng),可節(jié)省大量停機(jī)換刀的時(shí)間,可組成各種形狀復(fù)雜的刀具等優(yōu)點(diǎn)。
本次課題的目的便是設(shè)計(jì)一臺(tái)能重磨硬質(zhì)合金刀片的裝置及夾具，實(shí)現(xiàn)硬質(zhì)合金可轉(zhuǎn)位刀具中的刀片重磨。
通過查閱資料，擬定設(shè)計(jì)方案，設(shè)計(jì)硬質(zhì)合金刀片重磨裝置的機(jī)械系統(tǒng)，包括主運(yùn)動(dòng)系統(tǒng)和進(jìn)給運(yùn)動(dòng)系統(tǒng)。本設(shè)計(jì)說明書包括了主運(yùn)動(dòng)系統(tǒng)和進(jìn)給運(yùn)動(dòng)系統(tǒng)設(shè)計(jì)的相關(guān)計(jì)算，以及硬質(zhì)合金刀片重磨裝置重要零部件的校核驗(yàn)算，以及結(jié)構(gòu)設(shè)計(jì)和裝置的使用說明。
該設(shè)備設(shè)計(jì)旨在節(jié)約刀具材料及降低生產(chǎn)成本。因此，設(shè)計(jì)硬質(zhì)合金刀片重磨裝置具有重要的現(xiàn)實(shí)意義。

ABSTRACT

Because of the tools have hard alloy materials’s high hardness, high red rigid, high wearability, and long life and other advantages in production by a wide range of applications. Compared to ordinary welding carbide tools, Cemented carbide indexable cutting tools have more cutting performance, and high efficiency of production, long tool life, can save a lot of downtime tool change time, composed of various shapes of complex tool and so on.
The purpose of this task is to design a carbide blade-grinding plant and a fixture, and turning cemented carbide indexable cutting tools in the regrinding.
Through the consult material,draws up the design proposal, design carbide blade-grinding device mechanical system, including the main movement system and feed movement system. The design specification, including the main movement to movement into the system and the related system design, and carbide blade-grinding device important parts of the verification checking, and the structural design and installation instructions for use.
The device tool designed to save materials and lower production costs. Therefore, the design of carbide blade-grinding device has important practical significance.


Key words：Carbide, turning tool, regrinding
