Rotary plate type multi-station automatic flame brazing machine for household air conditioner silencer assembly

Abstract

The invention discloses a rotary plate type multi-station automatic flame brazing machine for a household air conditioner silencer assembly. The rotary plate type multi-station automatic flame brazing machine comprises a machine frame and an index rotary plate arranged at the top of the machine frame. Two welding devices and two wire feeding devices are arranged on one side of the index rotary plate. A plurality of wielding tools are arranged at the top of the index rotary plate. The whole machine adopts the rotary plate type multi-station design, servo wire feeding is adopted by the wire feeding devices, the wire speed and wire amount can be regulated and controlled, through a self-made reinforcement wire pressing device, wire feeding is stable, and slipping and wire stuck are avoided; through the self-designed welding tools, as for the same station, the left side is used for a former procedure, and the right side is used for a later procedure, so that finished products can be produced through one machine, the yield reaches 99.5% or above during usage, and the production takt is shorter than 8 second / set; the former and later procedure product can be met through the machine, finished products are obtained directly, and carrying and equipment input are reduced; two sets of products are perfectly compatible, gapless model change is achieved, machine debugging is avoided, and the equipment utilization rate is high; and the rotary plate type multi-station automatic flame brazing machine is suitable for being operated with robots and special machines online, and full-automatic manless production is achieved.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a turntable multi-station automatic flame brazing machine for household air conditioner muffler components. Background technique [0002] Flame brazing is the most commonly used production process in the production of household air conditioner muffler components. The brazing filler metal (copper-phosphorus welding wire BCu93P) is melted by flame heating, so that the two ports of the muffler (made of red copper) are connected with two pipes (made of red copper) respectively. ) are fused and connected to achieve the purpose of welding and sealing. The welding effect directly affects the quality of the air conditioner. At present, the production mode of the industry is mainly manual welding or semi-automatic welding, but it is still relatively backward, and the following problems generally exist: the efficiency is generally not high, and it varies from person to person; th...

AI Technical Summary

Problems solved by technology

At present, the production mode of the industry is mainly manual welding or semi-automatic welding, but it is still relatively backward, and the following problems generally exist: the efficiency is generally not high, and it varies from person to person; the labor intensity is high, and it is necessary to hold the welding torch tightly for a long time and stare at the strong light , high temperature in summer; the welding quality is poor in consistency and unstable, and the yield rate varies from person to person

For semi-automatic welding: the accuracy of equipment and tooling is poor, and it cannot be operated online with high-end equipment; the setting and arrangement of stations are unreasonable, and it is difficult to make a qualitative leap in welding quality; the compatibility of tooling design is poor, and the adjustment of the product is complicated and expensive. time; the welding flame and wire feeding are unstable, and the good product rate is not high, so special inspection and rework are required; the finished products of the silencer components need to be equipped with two sets of equipment for the front and rear processes
