【摘要】：近年来，随着我国钢管生产能力的不断提高以及市场经济的蓬勃发展,市场对于大口径、大壁厚、高钢级的钢管的需求逐渐增多。而目前国内外对于普通平头倒棱机的研究技术虽然已经比较成熟，但是随着钢管应用的领域扩大和发展,其存在的技术问题也随之浮现：包括倒棱机系统的稳定性有待提高、加工范围（管径、壁厚）有待扩大等。2004年，天津理工大学与长期进行钢管设备制造的公司合作，共同开发研制了拥有自主知识产权的钢管平头倒棱机。在此基础上，本文设计研制的新型全自动钢管铣头倒棱机能够实现大口径厚壁钢管的铣头倒棱，实现厚壁钢管生产的自动化、高效率，提高钢管生产水平。本文首先对研制的新型的钢管铣头倒棱机系统结构做了详细介绍：包括总体结构、动力头和进给机构。其中对于动力头又做了系统结构细分，分为电机、无级变速器、支撑箱体、大盘旋转传动机构、主轴动力系统和刀盘机构，并一一做了介绍。在两刀盘机构中，倒棱刀盘采用仿形浮动机构，能使倒棱加工满足要求的公差范围。该新型倒棱机能够满足加工范围的要求，其值能达到外径Φ426—Φ710mm，壁厚5—80mm。其次针对动力系统的加工工艺及参数，，进行了详细计算，选取合适的电机与变速器、设计齿形带传动与差动行星轮传动以及对于关键轴进行了强度校核和有限元分析。再次，运用Pro/ENGINEER软件对于动力头系统进行了简化建模与装配，模拟其运行状态，进行运动学分析。最后，简单地对于倒棱机控制系统进行了阐述与设计。
[Abstract]:In recent years, with the continuous improvement of steel pipe production capacity in China and the vigorous development of the market economy, the market for large caliber, large wall thickness, The demand for steel pipe of high steel grade is increasing gradually. Although the research technology of common flat head chamfering machine is mature at home and abroad, but with the expansion and development of steel pipe application field, In 2004, Tianjin University of Technology cooperated with a long-term steel pipe equipment manufacturing company, including the need to improve the stability of the chamfer system, and the need to expand the processing range (pipe diameter, wall thickness). On the basis of this, a new type of full-automatic steel pipe milling head chamfering machine is designed and developed, which can realize the milling head chamfering of large-caliber thick-walled steel pipe. Realize the automation and high efficiency of thick-walled steel pipe production, improve the production level of steel pipe. In this paper, a new type of steel pipe milling head chamfering machine system structure is introduced in detail, including the overall structure, power head and feed mechanism, in which the system structure of the power head is subdivided into motor, stepless transmission, etc. The supporting box, the rotating transmission mechanism, the main shaft power system and the cutter head mechanism are introduced. In the two cutter head mechanism, the chamfer cutter adopts the copying floating mechanism, The new chamfering machine can meet the requirements of machining range, and its value can reach 桅 426- 桅 710mm, wall thickness 5-80mm. secondly, the machining technology and parameters of power system are calculated in detail. Selecting suitable motor and transmission, designing gear belt transmission and differential planetary gear transmission, strength checking and finite element analysis for key shaft. Thirdly, simplified modeling and assembly of power head system are carried out by using Pro/ENGINEER software. Finally, the control system of chamfering machine is simply described and designed.
