A large wire reel automatic tube plate welding machine

Abstract

The invention discloses an automatic tube plate welding machine with a large wire disc, which comprises a welding machine head, a wire feeding device, a wire disc welding wire and a frame, wherein the wire disc welding wire is a large wire disc welding wire and positioned outside the welding machine head, the wire feeding device is positioned between the welding machine head and the large wire disc welding wire, and the frame comprises a frame cross arm mechanism; the welding machine head, the wire feeding device and the large wire disc welding wire are mounted in sequence on the frame cross arm mechanism; the large wire disc welding wire is connected to the welding machine head through the wire feeding device; and automatic tube plate welding machine further comprises a welding wire twist-prevention assembly. The automatic tube plate welding machine has the advantages that the large wire disc welding wire is a standard part which is economic and convenient for purchase; the problem of loose winding of a welding wire during manual wire winding is eliminated, and the welding wire twist-prevention assembly is added to ensure the welding quality; the large wire disc welding wire is positioned outside the welding machine and can be replaced and installed easily and rapidly, the frequency of replacement is greatly reduced to increase the production efficiency; and the probability of fault of the welding machine is reduced, and the service life of the welding machine is increased.

Description

technical field [0001] The invention relates to the field of automatic welding machines, in particular to an all-position automatic tube-sheet welding machine capable of using a large wire reel for wire supply. Background technique [0002] The automatic tube-sheet welding machine is usually used in the all-position tube-sheet automatic argon arc welding operation. Since the all-position automatic welding uses the workpiece to be fixed, the purpose of all-position welding is achieved by the rotation of the welding gun head itself, so in the welding work On the one hand, it is necessary to ensure the normal and stable rotation of the welding head, and on the other hand, it is necessary to ensure smooth delivery of the welding wire and avoid winding and twisting. [0003] Such as figure 1 As shown, it is a schematic diagram of the head structure of the existing small wire reel automatic tube plate welding machine, mainly including: small wire reel welding wire and welding wir...

AI Technical Summary

Problems solved by technology

[0006] First, the small reel welding wire is non-standard welding wire, which cannot be directly purchased in the market in some areas, and needs to be ordered from the manufacturer in advance. The unit price is twice as expensive as that of the large reel welding wire, which affects the procurement speed and increases the procurement cost.

[0007] Second, many manufacturers have to manually rewind the large reel welding wire into small reel welding wire, but it is time-consuming and laborious, and the loosening of the welding wire caused by manual winding will directly affect the quality of the final welding

[0008] Third, the small reel welding wire has a small volume and a short duration of use, so it must be replaced frequently, but the replacement and installation are troublesome and time-consuming. During long-term welding work, the work intensity of the operator will be increased, the work efficiency will be reduced, and the production capacity will be increased. production cost

[0009] Fourth, due to the short duration of the welding wire on the small wire reel, frequent wire changing operations will also affect the service life of the welding machine, resulting in failure of the welding machine
