Aluminum bus bar narrow gap mig welding special machine

Abstract

The invention relates to an aluminum busbar narrow-gap special MIG (Metal-Inert Gas) welding machine. The aluminum busbar narrow-gap special MIG welding machine consists of a welding gun telescopic device, a welding gun, an adjustable portal frame, clamping devices, a cooling device, a vertical sliding frame, a horizontal sliding frame, a sliding frame connecting plate, a positioning handle, an adjustable portal frame adjusting handle, clamping device tightness handles, a welding gun telescopic device adjusting handle and a control panel. Through the control panel, the automatic welding mainly for a pure aluminum and aluminum alloy narrow-gap welding seam with maximum welding depth of 200mm, minimum welding seam gap of 25mm and maximum welding seam length of 420mm is realized, the effect of welding the entire welding seam in one time is realized and the welding quality is guaranteed. Through the welding gun telescopic device adjusting handle, the welding gun is enabled to horizontally move relative to the welding seam and the position of the welding gun is corrected in real time. Through the positioning handle, the two clamping device tightness handles respectively on the left and the right and the adjustable portal frame fine adjusting handle, quick positioning and clamping are realized and the most proper welding state is guaranteed. Moreover, the structure is simple, the weight is light and the handling is facilitated.

Description

Technical field [0001] The invention relates to a welding machine in the field of welding, in particular to a special narrow-gap MIG welding machine for aluminum bus bars that can be positioned quickly and lightly. It is especially suitable for large-size welds, with a maximum welding depth of 200mm and a minimum weld gap of 25mm. Pure aluminum and aluminum alloy with a longest weld length of 420mm are butted with a narrow gap. Background technique [0002] The difficulty of pure aluminum and aluminum alloy welding lies in the two extremes, namely the welding of small and thin parts and the welding of large and thick aluminum ingots. For the current welding of large aluminum ingots, the maximum welding depth is 200mm and the minimum weld gap is 25mm. , The longest welding seam length is 420mm), the manual MIG welding is mainly used, the welding quality and welding rhythm cannot be controlled reasonably, it is random, and the welding efficiency is relatively low, which is no longe...

Problems solved by technology

[0002] The difficulty of welding pure aluminum and aluminum alloys lies in the two extremes, that is, the welding of small-sized thin parts and the welding of large-sized thick aluminum ingots. For the current large aluminum ingot welding, the limit specification is that the maximum welding depth is 200mm, and the minimum weld gap is 25mm. , the longest weld length is 420mm), mainly using manual MIG welding, the welding quality and welding rhythm cannot be reasonably controlled, it is random, and the welding efficiency is relatively low, which is no longer suitable for the current welding field. High efficiency and high quality requirements, especially in the narrow gap welding of large aluminum ingots, the above problems are more serious in manual MIG welding

At the same time, in the current field involving the welding of large aluminum ingots, dozens of layers of welding seam often need to be welded, which requires a long welding time. At the same time, aluminum welding needs to maintain a reasonable interlayer temperature and strict welding parameters, so generally All one seam needs to be welded at one time. For manual MIG welding, it is more difficult to control the labor intensity.
