A portal-type automatic welding and gouging integrated machine for welding steel pipe rods

Abstract

The invention discloses a gantry-type automatic welding and gouging integrated machine for welding steel pipe rods, wherein the gantry frame is a door frame type rack formed by two vertical posts and one cross beam; the cross beam of the gantry frame is provided with a welding machine and a solder wire feeding machine. A crosswise cast iron convex guide rail on a crosswise dragging plate is in sliding match connection with a protruded grooved track on lateral side of the cross beam of the gantry frame; and the cross beam of the gantry frame is provided with a welding arm crosswise walking motor and a welding arm crosswise reducer, so as to provide power for the crosswise movement of the welding arm. Supporting guide rails on bilateral sides of the welding arm are in sliding match connection with vertical sliding chutes on the crosswise dragging plate; and the crosswise dragging plate is provided with a welding arm vertical walking motor and a welding arm vertical reducer, so as to provide power for the vertical movement of the welding arm. Compared with the prior art, the provided gantry-type automatic welding and gouging integrated machine for welding steel pipe rods is able to increase the comprehensive welding efficiency, quality and aesthetic measure of the product, and reduce the cost thereof.

Description

technical field [0001] The invention relates to a numerical control machine tool, in particular to a portal-type automatic welding and gouging integrated machine for welding steel pipe rods. Background technique [0002] Due to its simple structure, clear force, easy processing, convenient construction, safe and reliable operation, and less maintenance workload, steel pipe poles have been more and more used in power grid transformation projects in recent years. [0003] The processing process of steel pipe rods is: blanking, bending, spot welding and assembly, full welding of all welds, galvanizing or painting. Among them, the steel pipe shaft is generally fully welded by submerged arc welding after the direct welding seam of the steel pipe shaft. However, submerged arc welding has the following disadvantages for the straight weld seam of the pipe body: due to the uneven width of the welded seam after the pipe is joined, submerged arc welding has high requirements for the s...

Problems solved by technology

However, submerged arc welding has the following disadvantages for the straight weld seam of the pipe body: due to the uneven width of the welded seam after the pipe is joined, submerged arc welding has high requirements for the seam, so there must be a manual welding before the bottom, which is low in efficiency and poor in quality Instability directly affects the quality of the submerged arc welding seam; secondly, the large current of the submerged arc welding machine is not suitable for welding thin-walled workpieces; and the loss of submerged arc welding flux is large, the cost is high, and the efficiency is low
