Electric welding machine system with built-in welding smoke innocent treatment mechanism

Abstract

The invention discloses an electric welding machine system with a built-in welding smoke innocent treatment mechanism, and relates to the technical field of electric welding machines. A welding tool special for butt joint of large-caliber steel pipes is researched and developed according to the requirements of the large-caliber steel pipes during butt joint machining treatment, the work is achieved in such a way that two runways are symmetrically and fixedly installed on the top end face of an equipment bearing base plate, the sliding end faces of the two runways are slidably connected with adriving mechanism, a driven mechanism and two sets of pipe head connecting supporting mechanisms correspondingly, a driving adjusting mechanism and a driven adjusting mechanism which are of the same structure are connected above the driving mechanism and the driven mechanism in a rolling mode correspondingly, the steel pipe A and the steel pipe B are driven to rotate synchronously through rotationof the welding tool, according to the tool of the structure, a welding robot is taken as the center, it is not needed that an existing welding robot has the multi-point, multi-thread and multi-dimensional welding function, and therefore the early-stage investment cost and the later-stage maintenance cost of an enterprise are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of electric welding machines, in particular to an electric welding machine system suitable for the butt joint processing of large-diameter steel pipes and having a built-in harmless treatment mechanism for welding fume. Background technique [0002] At present, with the continuous advancement of technology and market demand, steel pipes are developing in the direction of high steel grade, high pressure, and large diameter. During the butt joint process of large-diameter steel pipes, the two need to be welded by means of an electric welding machine system. The method forms a whole, which is convenient for subsequent actual usage scenarios. [0003] In the prior art, for the butt joint processing of two large-diameter steel pipes, the electric welding machine system used has the following defects in the actual use process: [0004] 1. When the existing electric welding machine system is welding the joints of ...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the deficiencies of the prior art, the present invention provides an electric welding machine system with a built-in welding fume harmless treatment mechanism, which solves the problem that the existing electric welding machine system is not suitable for large-diameter steel pipes when welding the joints of large-diameter steel pipes. The matching welding tooling forces the entire electric welding machine system to center around large-diameter steel pipes. In this way, the entire electric welding machine system must meet multi-point, multi-thread and multi-dimensional welding requirements. Such an electric welding machine system is not only complex in structure, but also It is difficult to maintain in the later period, and requires a large amount of capital investment and lacks the rapid collection and treatment of welding fumes, which in turn causes the problem that toxic welding fumes affect the health of workers
