An automatic water spray welding device and pipe fitting welding machine

Abstract

The invention discloses an automatic water-spraying welding device, comprising a welding tool tray on which workpieces to be welded can be placed, a circulating water tank is connected to the liquid accumulation area of ​​the welding tool tray, and the circulating water tank sprays cold liquid on the workpiece to be welded through a circulating liquid infusion pipeline mechanism contact, thereby cooling the workpiece during welding. Also disclosed is a pipe fitting welding machine, which includes a plurality of tooling support cylinders installed on a welding tooling plate, the tooling support cylinders are used to sleeve and position the tubular workpiece to be welded, and the above-mentioned automatic water spray welding device to be welded. Through the pressure valve and the water pump, the water is pumped from the lower circulating water tank to the automatic water spraying at the welding place, so as to realize the automatic water spraying and cooling operation; the purpose of cooling the welding point is efficiently and quickly achieved, and the welding quality inspection can be carried out quickly.

Description

technical field [0001] The invention belongs to the technical field of electrical appliances, and in particular relates to an automatic water spray welding device and a pipe fitting welding machine. Background technique [0002] The welding technology of silencer for air-conditioning pipe fittings is mostly used in the welding of four-way valve pipe fittings of air-conditioning external units. During the welding process, since the traditional welding technology adopts manual welding, employees need to prepare a damp cloth in advance before welding, and cover the damp cloth on the welding process. Next to the welding point of the muffler, in order to achieve the cooling protection, the process requires repeated operations and there is a waste of action, which is a non-value-added action and violates the principle of action economy. [0003] The traditional welding technology is used to weld the muffler. Due to the high welding temperature and the good thermal conductivity of ...

AI Technical Summary

Problems solved by technology

[0002] The silencer welding technology of air-conditioning pipe parts is mostly used in the welding of four-way valve pipe parts of air-conditioning external units. During the welding process, because the traditional welding technology uses manual welding, employees need to prepare wet cloth in advance before welding. Next to the solder joints of the muffler to achieve cooling protection. This process requires repeated operations and wasteful actions. It is a non-value-added action and violates the principle of action economy.

[0003] Use traditional welding technology to weld the muffler. Due to the high welding temperature and the good thermal conductivity of the copper pipe, the temperature is high during the welding process. The muffler coating has a risk of burning out, which is not conducive to quality control. Generally, the method of covering with wet cloth is used to control the quality. , then, natural cooling into the next process

[0004] Due to the requirements of the welding process of the air-conditioning pipeline, the solder joints need to be inspected after the welding is completed. During the inspection, the muffler needs to be cooled after welding to avoid the risk of burns for the operator. However, the traditional cooling method is to cover the welding process with a wet cloth and then cool it naturally , the cooling efficiency is low, and the synchronization results in low efficiency of solder joint quality inspection
