Design And Research Of Saddle-seam Automatic Welding Machine

With a wide range of pressure vessel used in the industrial production, saddle-shaped curve seam welded pipe and tube Intersecting formation has also become an important factor affecting the quality of the pressure vessel. In order to solve the manual welding seam at the saddle-shaped curve quality is not good enough, not efficient problem saddle realize automatic seam welding has become an important research direction in this field. In this paper, the following tasks:1.Of the saddle seam automatic welding machine system motion a program selection, combined with the characteristics of tube and tube orthogonal mutually intersecting,using two welding arms while working under the premise of guaranteeing quality and improving work efficiency.2.Determine the saddle seam automatic welding machine movements and agency-specific parameters,3D solid modeling by Solidworks software.which provides the basis for the physical prototypes following; key drive components of the mechanical system has been checked to ensure that all components are reliable; calculate column and beam about the finite element simulation analysis through static analysis and dynamic analysis to ensure their reliability and to avoid unfavorable operating frequency of the design.3.The machine will make a three-dimensional model of a virtual prototype kinematics simulation proved the feasibility of automatic seam welder saddle mechanical device efficiency.4.By entering the function statement in Matlab software, can be arbitrarily determined size pipe and tube orthogonal saddle-shaped curve formed by three servo motors to produce at the time of the drive splines in Adams software to production spline curve as the driver of the saddle seam automatic welder machine kinematics simulation, trajectory simulation of actual joints to record and compare with the theoretical saddle-shaped curve, with good results, verify the saddle automatic seam match welding machinery and driving is very appropriate.
