Spot welding machine for radiating fins

Abstract

A spot welding machine for radiating fins belongs to the technical field of welding machinery and comprises a frame, an upper spot welding mechanism, a lower spot welding mechanism and a radiating fin conveying mechanism. The frame comprises a pair of vertical columns and a beam, and an air storage tank is arranged on the beam. The upper spot welding mechanism comprises a first base, an upper spot welding device and an upper spot welding machine, the lower spot welding mechanism comprises a second base, a lower spot welding device and a lower spot welding machine, the upper spot welding device comprises a first cylinder, a first connector, a first cable, a first spot welding head and a first cylinder seat, and the lower spot welding device comprises a second cylinder, a second connector, a second cable, a second spot welding head and a second cylinder seat. The spot welding machine has the advantages that the spot welding efficiency of the radiating fins is improved, equipment investment can be saved, occupied space of a production site is decreased, labor resources are saved, regular effects of welding spots can be particularly guaranteed so that the welding quality of the radiating fins is ensured, and the cables and the spot welding heads can be effectively cooled so that the service lives of the cables and the spot welding heads can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of welding machines, in particular to a heat sink spot welding machine. Background technique [0002] As known in the industry, in order to make the transformer (oil-immersed transformer) operate normally, it is usually necessary to install a radiator on the side and / or upper part of the transformer, and the radiator will play the role of reducing the temperature rise of the transformer. Get a full understanding of the patented technical solutions that are not limited to those listed below and disclosed by Chinese patent documents. Such as CN201084519Y (transformer radiator), CN101339838A (radiator ladder radiator), CN201185118Y (transformer radiator), CN201185115Y (radiator with fan base), CN201185117Y (transformer radiator), CN201256051Y and CN101388275A (transformer heat exchanger using evaporative cooling technology), etc. [0003] Furthermore, as known in the industry, the transformer fin radiator is ...

AI Technical Summary

Problems solved by technology

The current solution is to increase the number of spot welders to meet the production requirements of radiators. However, this measure is originally a negative measure, because it not only increases the investment in equipment, occupies valuable production space, but also increases the number of labor forces. , especially the spot welding position is uneven, that is, whether it is in the horizontal or vertical direction, it is difficult to align the position of the welding spot, which not only affects the viewing effect, but also makes it difficult to guarantee the quality of spot welding

[0005] Even in the "welding machine for radiator fins" recommended by Chinese patent utility model authorization announcement number CN201950359U and "a special welding machine for radiators" provided by CN201493618U It is also difficult to plan a spot welding machine that can make up for the aforementioned shortcomings under the inspiration of the technical content of the

[0006]In addition, since the spot welder will generate high temperature during operation, there are two forms of high temperature. One is that the cable will heat up when a large current flows through the cable, and even burn the cable The second is that the spot welding head generates high temperature during spot welding, which affects the service life of the spot welding head

However, in the prior art, there is no enlightenment that can effectively cool the cable and the spot welding head
