Description
Technical Field
The invention relates to an arc striking and extinguishing plate mounting tool, and belongs to the technical field of welding tools.
Background
The bogie frame with the welded structure is widely applied to various types of vehicles such as railway freight cars, passenger cars, locomotives, motor train units, subways and the like at home and abroad. The frame is used as the basic part of the bogie, and the parts and components on the bogie are integrated to bear and transmit various acting forces and loads. The frame structure is complex, and is subjected to various forces and loads, so the welding of the frame has very strict requirements, the welding quality of welding seams directly determines the performance of the frame, and the assembly welding of cross beams and the assembly welding of side beams of most bogie frames at home and abroad at present widely use butt welding seams to connect the whole frame into a whole.
In a framework welding structure, important welding seams, particularly butt welding seams commonly used in framework component assembly welding, in order to avoid welding defects generated in the process of welding arc striking and arc extinguishing, arc striking and arc extinguishing plates need to be designed at the end parts of the two ends of the butt welding seams, welding is carried out from the ends of the arc striking plates during welding, and thus a section with stable welding parameters in the welding process is positioned at an important part of a component, and the welding quality is ensured to be stable and reliable. During welding, arc striking is carried out from the protruding part at one end to arc extinguishing at the protruding part at the other end, and the arc striking plate and the arc extinguishing plate are cut off after welding is finished. Although this leaves a section with better welding control in the welded main structure, which improves the welding quality of the frame, there are great disadvantages of complicated design structure, material waste, and increased processing time.
The welding arc striking and arc extinguishing structure left on the base metal of the welding component has the characteristics of convenient welding and space saving, and has a great risk point. The arc striking and extinguishing plates need to be cut off after welding is finished, and due to the influence of welding deformation, the body part of the component is easily cut off when the arc striking and extinguishing plates are cut off, so that the quality of the framework is influenced.
The existing arc striking and arc extinguishing plates which are independent of the base metal need to be flatly arranged with the base metal and are in good contact with the base metal, the installation of the arc striking and arc extinguishing plates is time-consuming and labor-consuming, and the installation quality is unstable.
