Stainless steel component for heating radiator and manufacturing method thereof

Abstract

The invention relates to an auxiliary pressure plate for hot water radiators, in particular to a thin-wall radiator used for indoor heating and employing hot water or steam as a heat source, and belongs to indoor heaters. Two rolled drawn transverse tubes and more than two vertical tubes are welded into a rectangle or square; two ends of each vertical tube are punched into concave arc shapes; each rolled drawn transverse tube is evenly provided with concave arc shapes and drawn turnup steps in the lengthwise direction by punching; the concave arc shapes and the drawn turnup steps of the rolled drawn transverse tubes fit the concave arc shapes of the two ends of the vertical tubes. Aiming to the defects that the copper-aluminum or aluminum-plastic radiators are high in manufacturing cost and that the steel-aluminum low-carbon steel radiators easily leak due to corrosion, the radiator is in the unique stainless steel ultra-thin design and is uniquely welded through a fixture; arc U-shaped openings are ingeniously used in welding, edges are aligned and tightly kneaded so that service life is ensued, work efficiency is improved, costs are saved, and the radiator is attractive in price and quality.

Description

Technical field [0001] The invention belongs to the technical field of radiators, and specifically relates to a stainless steel component used for a heating radiator and a manufacturing method thereof. Background technique [0002] At present, composite radiators made of different materials have been widely used, and there are many structural forms. Among them, a common composite radiator component includes two upper and lower horizontal connecting pipes and a plurality of vertical vertical pipes arranged in parallel. The two ends of each vertical riser pipe are respectively connected to two horizontally communicating pipes, and the ends of the horizontally communicating pipes are provided with joint seats. The main components of the above composite radiator can be made of stainless steel. In a known prior art, the horizontal connecting pipe is provided with an outwardly convex annular flange, and the vertical riser is inserted and welded to the horizontal connecting pipe. Outsi...

AI Technical Summary

Problems solved by technology

The main components of the above-mentioned composite radiator can be made of stainless steel. In a known prior art, the horizontal communication pipe is provided with an outwardly protruding annular flange, and the vertical riser is inserted and welded on the horizontal communication pipe. outside the ring flange of the pipe, or insert and weld the vertical riser into the ring flange of the horizontal communication pipe. In these two through-connection methods, the welds are all on the outer surface, which affects the appearance of the stainless steel. When the welding temperature is unstable , especially for thin-walled stainless steel materials, it is easy to cause weak welding or breakdown, and at the same time, the heat-conducting medium will penetrate into the gap between the annular flange of the communication pipe and the vertical riser, which may cause corrosion to the weld; There is a prior art that the horizontal communication pipe is provided with an inwardly or outwardly protruding annular flange, and the vertical standpipe and the annular flange of the horizontal communication pipe are connected by threads or press-fitted. In order to ensure that the annular flange The side has a certain mechanical strength, which requires increasing the thickness of the stainless steel material used in the horizontal communication pipe, thereby increasing the material cost and product weight, and at the same time, the thread connection has poor sealing performance and is prone to leakage
