Manufacturing method of liquid accumulator formed through electric resistance welding

Abstract

The invention relates to the technical field of production processing, in particular to a manufacturing method of a liquid accumulator formed through electric resistance welding. An annular boss partis arranged on the edge of the bottom end of an upper cover or a lower cover, so that the outer diameter size of the boss part ensures that the outer diameter clings to the inner diameter of a shell and enables a welding area to be left between the upper cover or the lower cover and the shell; since the outer diameter of the boss part clings to the inner diameter of the shell, a limiting effect can be achieved during welding, and the occurrence of the phenomenon that the requirement for product quality cannot be met since the relative positions of a cover body and the shell body slide is prevented; meanwhile, since the outer diameter of the boss part clings to the inner diameter of the shell, during the welding of the shell body and the cover body, a welding assembly cannot flow into the shell after being hot-molten by electric resistance, so that the occurrence of the phenomenon that the product quality is influenced due to unsmoothness at the welding part caused by flowing is avoided; and in addition, through a welding area formed by the design, the welding area can be conveniently controlled to be powered on so as to generate electric resistance heat, and the detects such as high energy consumption, poor product quality, incapability of continuous action and low efficiency of a traditional over-furnace welding manner are overcome.

Description

technical field [0001] The invention relates to the technical field of production, processing, and specifically discloses a method for manufacturing a liquid reservoir formed by resistance welding. Background technique [0002] As an important part of the air-conditioning system, the liquid receiver is suitable for the suction end of the compressor. Its function is to absorb the refrigerant that has passed through the refrigeration cycle of the air conditioner, filter it and transport it to the compression chamber of the compressor for the next round of refrigeration cycle. Due to the refrigeration cycle, a small amount of refrigerating machine oil and impurities are mixed into the refrigerant, and affected by the surrounding low temperature environment, the refrigerant condenses into small droplets. Through the liquid storage tank, the impurities are filtered, and the oil droplets and refrigerant droplets are atomized at the same time, and then enter the refrigeration cycle...

Problems solved by technology

[0003] The production and processing process of the liquid reservoir needs to weld its various parts to form a complete liquid reservoir. However, most of the current liquid reservoirs are welded through the furnace. This method has high temperature and high energy consumption, and the welding speed is slow, which is not conducive to Continuous operation, which leads to low efficiency in manufacturing the reservoir, and the leakage of the reservoir is difficult to control, which is not conducive to ensuring product quality
