Embodiment Construction

[0025] Such as figure 1 , 2 , 3, 4, 5, 7, 8, and 9, a submerged arc automatic welding tool 1 for a spherical head is composed of two runners 11, a worktable 13, and eight sets of fixed splints 12. The two runners 11 are respectively fixed on the two ends of the workbench 13, and the eight groups of fixed splints 12 are respectively symmetrically arranged on the upper and lower planes of the workbench 13 close to the runners 11, and the workbench 13 The thickness H is equal to 2 times of the spherical segment h of the spherical segmental head 20 (ie H=2h), and the two runners 11 are placed on the rollers 4 respectively, and the rollers 4 are driven by a motor and a reducer.

[0026] Such as Figure 6 , 10 , 11, and 12, the fixed splint 12 is composed of a front splint 121 with a circular arc, a rear splint 122 with a circular arc and a rib 123, and the front splint 121 with a circular arc and the rear splint with a circular arc The arc of 122 coincides with the spherical sh...

Abstract

The invention discloses a submerged automatic arc welding tool for a segment-shaped seal head, relates to a welding tool for spherical seal heads, and solves the problems of low welding efficiency, low welding line quality and heavy welding fume pollution in the prior art. The tool consists of two rotating wheels, a workbench and eight groups of fixing clamping plates, wherein the two rotating wheels are fixed at the two ends of the workbench respectively; the eight groups of fixing clamping plates are symmetrically arranged on the upper plane and the lower plane of the workbench close to the rotating wheels respectively; the thickness H of the workbench is two times that h of the segment of the segment-shaped seal head; and the two rotating wheels are arranged on a roller respectively, and the roller is driven by a motor and a speed reducer. The thickness of the workbench just makes up the segment of two spherical seal heads, so that a sphere is formed and rotates around a fixed axis; and the tool can be used for performing submerged automatic arc welding. Therefore, the tool is suitable for the submerged automatic arc welding of large-diameter spherical seal heads.

Description

technical field [0001] The invention relates to a welding process device for a spherical head (abbreviated as a welding tool), in particular to a welding tool for realizing automatic submerged arc welding of a spherical segmented head. Background technique [0002] Spherical heads are the most common parts in pressure vessel manufacturing. At present, the large-diameter spherical head is pressed into "spherical petals" by splitting and welding. Such as figure 1 As shown, the spherical head is formed by pressing six pieces of spherical petals, which are butted on the platform to form a whole and fixed by spot welding, and then six longitudinal seams are welded into a spherical head. The existing welding process is as follows: the welder first longitudinally seams from the outside of the head, and uses electrode arc welding or C0 welding from bottom to top. 2 The method of gas shielded welding is used for welding, and then longitudinal seams are made from the inner surface ...
