An automatic welding manufacturing method for stainless steel pipe rings for the above-mentioned heating radiator, comprising the following process steps:

Step 1: The vertical riser is a rough pipe, not a finished pipe. The vertical riser is elliptical. The oval shape of the vertical riser is the welding deformation of the steel pipe factory. The end faces need to be manually spot-welded to form a pipe row structure, so that the end faces of the vertical standpipes are flush with the end faces of the annular flanges of the horizontal connecting pipe profiles.

Step 2: Place the spot-welded pipe row structure with fin heating radiator on the frame structure, position and clamp.

Step 3: After the end face of the vertical standpipe is flush with the ring flange of the horizontal connecting pipe, the inwardly protruding ring flange of the horizontal connecting pipe does not fit closely with the pipe wall of the vertical standpipe, which needs to be done manually Use cylindrical cones to punch a full circle, and the full circle can reach a non-elliptical shape, or use cylindrical cones in a row of porous equipment to punch a full circle at one time, punching a full circle to achieve a tight fit with the pipe wall, and the ring circle is to be implemented automatically welding.

After flushing, the inwardly protruding annular flange of the horizontal connecting pipe fits closely with the pipe wall of the vertical standpipe. It is inappropriate to carry out welding, because the vertical standpipe is caused by the welding deformation of the steel pipe factory, so all As long as the steel pipe is a welded pipe, it is a rough pipe, not a finished pipe, and it is elliptical. If the vertical vertical pipe forms an ellipse, it cannot be directly welded in a circle. There is a space between the pipe walls that is not really tightly fitted. There is a phenomenon of uneven and rotten gaps, and it is impossible to weld at a uniform speed around the circle. The present invention uses the real close fit between the pipe walls as the manufacturing method. The welding torch rotates around the vertical standpipe, and every turn of the welding torch circle is equivalent to welding a connecting pipe. At the same time, under the force of the disc spring, the welding torch turns around a circle to avoid repeated winding of the steam line; The concave channel steel in the structure is welded with a balance bottom bracket. The end faces of multiple vertical risers and the end faces of two horizontal communication pipes need to be manually spot welded by the operator to form a tube row structure, and the spot welding is made into a tube row structure with wings. The sheet heating radiator is placed on the frame structure. After positioning and clamping, it is convenient to implement the inwardly protruding annular flange of the horizontal communication pipe and the pipe wall of the vertical standpipe. ! Through the implementation of this process, the whole circle of the punching hole can reach the tight fit of the pipe wall, and the automatic welding of the circle is to be implemented.

The ring-circle automatic welding member for the heating radiator of the present invention only uses three channel steels to form a three-point tripod to complete the positioning and clamping of the heating radiator. The structure is simple, the replacement welding position is convenient and quick, and the cost is low; The reverse rotation of the steam line on the welding torch is completed by using the cheap reduction box assembly and the contraction force of the disc spring, which is leading in this field.

The manufacturing method of the present invention makes the end face of the welded connecting pipe straight, free of convex and concave phenomena, evenly sintered, tightly welded without water leakage, fast in speed and good in quality, fully meets the manufacturing requirements of the product structure, can ensure product quality, and is suitable for batch production Production.

By implementing the present invention, it is possible to make full use of the circular automatic welding member to produce a heating radiator with the performance of thin-walled stainless steel material, and to provide the market with composite radiators of various forms and materials. The present invention can also be directly used as a radiator product .

The radiator product produced by adopting the technology of the invention has reliable service life, beautiful appearance, light weight, saves material and labor costs, is suitable for mass production, and has good market prospect.
