Automatic water spraying welding device and pipe fitting welding machine

Abstract

The invention discloses an automatic water spraying welding device which comprises a welding tool disc capable of containing a to-be-welded workpiece, a liquid accumulation area of the welding tool disc communicates with a circulating water tank, the circulating water tank conducts cold liquid spraying contact on the to-be-welded workpiece through a circulating liquid conveying pipeline mechanism,and therefore the to-be-welded workpiece is cooled during welding. The invention further discloses a pipe fitting welding machine which comprises a plurality of tool supporting cylinders installed onthe welding tool disc and further comprises the above automatic water spraying welding device to be welded. The tool supporting cylinders are used for being connected with the to-be-welded tubular workpiece in a sleeved mode and positioning the to-be-welded tubular workpiece. Through a pressure valve and a water pump, water is pumped from the lower circulating water tank to a welding position forautomatic water spraying, so that automatic water spraying and cooling operation is achieved; and the purpose of welding spot cooling is efficiently and rapidly achieved, and rapid welding quality detection is guaranteed.

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 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 welding point of the muffler, in order to achieve the left and right sides of the cooling protection, this process requires repeated operations and wastes actions, which 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 w...

[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
