【摘要】：钢筋笼滚焊机是现代化建设工程中必不可少的建筑机械设备之一,广泛用于桥涵、高铁等现代化建设工程中。钢筋笼滚焊机结束了传统钢筋笼一贯手工捆绑的历史,为我国大型建筑的制造提高了效率,具有加工速度快,加工质量稳定可靠等特点。然而传统钢筋笼滚焊机加工生产出来的钢筋笼的横截面一般为圆形,形状过于单一,并且采用人工试制的方法对焊点进行逐一焊接,有时甚至会导致漏焊的状况,其加工效率远远达不到现代化建设的基本要求。为了满足现代化建设的需求,提高钢筋笼滚焊机的加工效率,考虑到钢筋笼加工时,由箍筋与主筋的搭接点形成的焊点的运动特性与箍筋材料的力学性能,在传统滚焊机的基础上设计了能够加工多边形钢筋笼的多边形成型以及自动焊接装置。该装置不仅能够在钢筋笼加工过程中,将两条主筋之间的箍筋由曲线形压为直线形,还具有对运动焊点进行自动捕捉的特点,并且能够在捕捉后对焊点进行追踪焊接,提高了钢筋笼焊接装置的自动化水平和生产效率。主要研究内容有以下几点:(1)针对钢筋笼滚焊机加工钢筋笼的特点,研究钢筋笼螺旋角形成方法,对钢筋笼加工过程中的箍筋进行受力分析,获取箍筋受力达到极值的瞬时状态,建立多边形钢筋笼轮压成型基本方案。(2)设计了一种自动捕捉焊接方法。根据由箍筋与主筋的搭接点形成的焊点的运动特性,研究了一种针对于钢筋笼滚焊机的自动捕捉追踪焊接方法,并对焊接的方案进行分析选择,利用气缸作为动力推进,并对气缸的型号进行计算选型。(3)对钢筋笼滚焊机的多边形轮压成型以及自动焊接装备进行结构设计,利用CATIA V5 R20软件建立该装置的三维模型。再使用ANSYS有限元分析软件对多边形钢筋笼轮压成型装置中的带压轮支架的压轮旋转装置和自动焊接装置上的焊枪安装装置进行静力学校核。
[Abstract]:The steel cage roller welder is one of the necessary construction machinery and equipment in the modernization construction project, and is widely used in the modern construction projects such as bridge and culvert, high-speed rail and so on. The steel cage roller welder has ended the history of the traditional steel cage manual binding, and has improved the efficiency for the manufacture of large buildings in our country, and has the characteristics of fast processing speed, stable and reliable processing quality, and so on. However, the cross section of the steel cage produced by the traditional steel cage roller welding machine is generally circular, and the shape is too simple, and the welding joint is welded one by manual trial, which sometimes leads to the condition of leakage welding. Its processing efficiency is far from reaching the basic requirements of modernization construction. In order to meet the needs of modernization and improve the processing efficiency of the steel cage roller welder, considering the motion characteristics of the joint formed by the lap joint of stirrups and main bars and the mechanical properties of stirrups, Based on the traditional roller welding machine, a polygon forming and automatic welding device is designed to process polygonal steel cage. The device not only can compress the stirrups between the two main bars from curved shape to straight shape, but also can automatically capture the moving solder joint, and can trace the welding joint after capture. The automation level and production efficiency of the steel cage welding device are improved. The main research contents are as follows: (1) in view of the characteristics of steel cage roller welding machine, the forming method of spiral angle of reinforcing bar cage is studied, and the force of stirrups in the process of reinforcement cage processing is analyzed, and the instantaneous state of stirrups force reaching maximum value is obtained. A method of automatic capture welding was designed. According to the motion characteristics of solder joints formed by lap joint of stirrups and main bars, an automatic capture and tracking welding method for steel cage roller welder is studied, and the welding scheme is analyzed and selected, and the cylinder is used as dynamic propulsion. The structure of polygon wheel compression molding and automatic welding equipment of steel cage roller welder is designed by calculating and selecting the type of cylinder. The 3D model of the device is established by using CATIA V5R20 software. Then the ANSYS finite element analysis software is used to check statically the rotary device with the pressure wheel support and the welding torch installation device in the polygonal steel cage wheel press forming device.
