Processing method for main pipe of stainless steel water collecting and distributing device with plane lug boss

Abstract

The invention relates to a processing method for a main pipe of a stainless steel water collecting and distributing device with a plane lug boss. The production process of the main pipe comprises the steps such as material preparation, pipe coiling, welding and reshaping, lug boss forming, punching, inner side flanging, necking, outer side flanging, turning, grinding and polishing. In the work procedure of punching, plugged inner dies are at least three overlapped steel plates and aim at bringing convenience to the taking-out of a mould after the punching is carried out; lug bosses matched with the inner wall of a pipe lug boss in shape are arranged on the steel plates on two sides of the main pipe; and punching holes are formed in the central positions of the steel plates, which are positioned on the lug bosses. According to the main pipe of the stainless steel water collecting and distributing device, which is produced by using the processing method, stainless steel is fully utilized and interface threads are not required to be additionally welded; the whole production process is finished at one step; and products can be produced by a semi-mechanical or full-automatic way so as to facilitate the serialization formation of the products. The formed main pipe of the stainless steel water collecting and distributing device has the advantages of smooth inner wall, small viscosityresistance of fluid, attractiveness and elegance in appearance, firmness for mounting of a control valve and no limit to the number of branches.

Description

technical field [0001] The invention relates to the processing process of tubular plumbing equipment, in particular to a processing method for the main pipe of a stainless steel water collecting and distributing device with a flat boss. Background technique [0002] In chemical, pharmaceutical, petrochemical, brewing, food, beverage and other enterprises, in order to centrally supply and distribute water, oil, steam and other fluid materials, it is often necessary to establish a centralized distribution control console, that is, a fluid collector. In recent years, this fluid collection and distribution system has been applied to the living facilities of family houses. For example, central heating of contiguous residential quarters in northern my country, gas supply from liquefied gas stations, solar water heater water supply stations, etc. In some cities in the Yangtze River Delta region, a hot water collection and distribution system in which domestic gas water heaters pro...
