Problems solved by technology
[0003] In actual use, due to the high temperature generated during welding and the accumulation of welding times, the crimping part of the conductive plate that presses the edge of the tail pipe straight seam will be worn, resulting in the inability of reliable compression of the conductive plate and affecting the welding quality. And it is necessary to replace the conductive voltage plate as a whole, but the overall size of the conductive voltage plate is large and the cost is high, and the waste of direct overall replacement is very serious

The invention discloses a straight seam welding machine. The straight seam welding machine comprises a work panel (1), an installation base (2) and an electricity conducting pressing plate (3); the electricity conducting pressing plate (3) comprises a plurality of electricity conducting pressing blocks (4). Each electricity conducting pressing block (4) comprises an edge pressing part (4.1) for tightly pressing a straight seam edge part of a welded piece, an installation part (4.2) used for being installed in the installation base (2) and an installation section (4.3) for connecting the edge pressing part (4.1) with the installation part (4.2); the edge pressing part (4.1) is provided with a flat bottom; a holddown spring (5) of which the top tightly abuts against the bottom of the work panel (1) is installed on the installation section (4.3); the inner end of the edge pressing part (4.1) is provided with a threaded connection rod (4.11); and the end of the installation section (4.3) is provided with a threaded hole (4.32) which is in threaded connection with the threaded connection rod (4.11). The electricity conducting pressing plate (3) of the straight seam welding machine does not need to be replaced overall, the replacement cost can be effectively reduced, and pressing still can be conducted under the abrasion state.
Description
Technical field [0001] The invention relates to the technical field of straight seam welding of automobile tail pipes, in particular to a straight seam welding machine. Background technique [0002] At present, the more common longitudinal seam welding machine generally includes two symmetrically arranged voltage conducting plates, and a conductive support shaft located below the butting place of the two voltage conducting plates, wherein a gap is left between the voltage conducting plate and the conductive support shaft. When welding is needed, sleeve the tail tube with straight seams on the lower support shaft, and the two conductive voltage plates respectively press the two edges of the tail tube straight seam on the conductive support shaft, and start the welding machine to start the straight seam of the tail tube. Perform welding. [0003] In the actual use process, due to the high temperature generated during welding and the accumulation of welding times, the blanking part o...
