   鋼管自動(dòng)切斷倒角機(jī)床是帶式輸送機(jī)托輥鋼管切斷、兩端倒角一次自動(dòng)完成的專(zhuān)用設(shè)備。除上料外，其余工序（送料、定位、夾緊、倒角、切斷）在此機(jī)床上依次自動(dòng)進(jìn)行。其自動(dòng)化程度高，一次即能滿(mǎn)足鋼管的加工精度，不需要輔助加工，并且安裝簡(jiǎn)單，調(diào)整方便。另外采用硬質(zhì)合金刀（YT5系列），其硬度高，耐磨性，耐熱性都很高，切削速度遠(yuǎn)比一般高速鋼快的多，使得其使用壽命大大延長(zhǎng)。在液壓系統(tǒng)的使用上，采用雙聯(lián)泵供油，保證穩(wěn)定的工作速度，切斷采用進(jìn)口調(diào)速出口背壓裝置，使得速度可調(diào)，安全可靠?？刂葡到y(tǒng)采用可編程控制器（PLC）為中心，限位采用無(wú)觸點(diǎn)開(kāi)關(guān)，動(dòng)作程序準(zhǔn)確連續(xù)。整個(gè)加工過(guò)程，由“自動(dòng)送料—送料到位—夾緊—夾緊到位—進(jìn)刀—進(jìn)刀到位—自動(dòng)落料—放松退刀—退刀到位—自動(dòng)送料”循環(huán)進(jìn)行，工作效率大大提高，適用于大批量的專(zhuān)業(yè)化生產(chǎn)。

Title    The design of chamfering machine for cutting steel pipe automatically                    

Abstract
The chamfering machine for cutting steel pipe automatically is a special equipment which could cut off and chamfer at both ends the belt conveyor idlers pipe auto-completely at once. In addition to feeding, the other processes(feeding ,positioning, clamping, bevel, cut off) followed by automatic in this machine. For high degree of automation, a steel pipe that can meet the processing precision, does not require auxiliary processing, and easy-to-install ,To facilitate adjustment.And it is equipped with carbide tool(YT5 series)that has hardness, abrasion resistance, high heat resistance, cutting speed faster than the general high-speed steel, making its service life significantly to extend.Double pumps supply the oil to ensure stability in the pace of work, it uses exports of back-pressure device and adjusts speed at imports ,making adjustable speed,safe and reliable.The control system use PLC as the center.The limited switch is
no touch, accurate procedure for action. The course of working as follow: automatical feed-feed in position-clamp-clamp in position-sumping-sump in position-sumping-sump in position-automatical blanking.The cycle can improve the work efficiency and work with a batch of workpiece.
