钢管自动切断倒角机床设计（QZ11-16×220）

毕业设计（论文）中文摘要

钢管自动切断倒角机床（QZ11-16x220）是带式输送机托辊钢管切断、两端倒角一次自动完成的专用设备，该机床自动化程度高、加工精度高，如送料，定位，夹紧，倒角，切断依次进行，一次就能满足钢管的加工精度，不需要辅助加工，并且安装调试方便。该设备采用的是硬质合金刀（YT5系列刀具），其硬度，耐磨性，耐热性都很好，切削速度远比高速钢快得多。液压系统中使用了双联泵供油，保证了运动速度，切断采用进口调速出口被压装置，使切断速度可调、工作稳定。控制系统采用可编程控制器(PLC)为中心，限位采用无触点开关，动作程序准确可靠。钢管加工过程，由“自动送料—送料到位—夹紧—夹紧到位—进刀—进刀到位—自动落料—放松退刀—退刀到位—自动送料”循环进行，大大提高工作效率，并能适应大批量生产加工。

Title  The chamfer machine tool for cutting steel pipeautomatically

        
Abstract
The chamfer machine tool for cutting steel pipe automatically.（QZ11-16x220）。The chamfer machine tool provides various working procedures for cutting the steel pipe automatically such as feeding, positioning, clamping, chamfer and cutting. The automaticity is good. It can satisfy the machining precision of the steel pipe and not need assistant machine. The installation and debugging of the equipment is convenient. This equipment is equipped with carbide tool （YT5 series） which is better than high-speed steel knife. The hardness, wear resistance and thermostability of the tool are perfect. Two pumps supply the oil to satisfy the parameters in the hydraulic system. The control system use PLC as the center. The limited switch is no touch. The course of working as follow:  automatic feed-feed in position-clamp-clamp in position-sumping-sumping in position-automatic blanking. The cycle can improve the work efficiency and work with a batch of workpiece.
