Abstract
The utility model relates to a welding structure, in particular to a multi-wire welding mechanism of internal welding of a spiral welded pipe, comprising a welding arm; and the welding arm is provided with a wire feeding pipe. The multi-wire welding mechanism of internal welding of the spiral welded pipe is characterized in that the wire feeding pipe is a flexible wire feeding hose; the front end of the flexible wire feeding hose is provided with a wire feeding machine head; the welding arm is also provided with a three-dimensional adjusting mechanism; and the wire feeding machine head is fixed on the three-dimensional adjusting mechanism. The multi-wire welding mechanism has the advantages of high transmission accuracy, high stability, strong bearing capability, strong adaptability, capability of realizing single-wire welding, double-wire welding and multi-wire welding by one equipment and convenient installation and adjustment.
Description
Technical field
The utility model relates to a kind of Welding Structure, specifically is weldering multifibres welding mechanism in a kind of spiral welded pipe, and its good stability, weight capacity is strong, tracking accuracy is high.
Technical background
In the spiral seam welding steel pipe production process, there are differences between one-tenth groove part helix that month shape is curved because roll bending exists, the roll bending working width changes, caliber size variation or other reasons etc. may cause spiral welded pipe reality and the desirable helix, cause weld seam that a minor shifts is to the left or to the right arranged, must take certain measure, the skew of welding torch and weld seam is consistent, to avoid weldering partially; Also to change the timely height of adjusting welding torch to keep normal welding wire elongation simultaneously, guarantee the weld appearance shape according to caliber.Be manually to adjust or automatic adjustment all must have reliable executing agency, this executing agency is exactly the weld joint tracking slide unit.The quality of following the tracks of slide unit is directly determining the effect of adjustment, and what directly the influence welding was produced normally carries out.So weld joint tracking executing agency--weld joint tracking slide unit is a spiral weld submerged-arc welding steel pipe production line visual plant, is all indispensable equipment of any one spiral submerged arc welded pipe production line.
In addition, because the production trend of spiral welded steel pipe is to high grade of steel, heavy wall development, in order to guarantee filling molding of weld seam, and guarantee that weld seam has the good surface appearance shape, the welding of inside weld is also by monofilament progress of weld mariages, three or multifibres weldering development.
But traditional inside weld tracking, adjustment and welding mechanism exist more problem, can not adapt under the new situation quality requirement and manufacturing requirements to spiral welded steel pipe, and butt welding delivers a child to produce considerable influence.Tradition tracking, adjustment and welding mechanism subject matter are as follows:
1. tracking accuracy is low.The transmission mechanism of tradition follower is trapezoidal threaded lead screw, screw, drives coattail board, and machining accuracy is low, and easy to wear, causes tracking accuracy low.
2. transmission is dumb.Leading screw, screw drive coattail board, and panel has been pressed pine, poor stability, and tracking accuracy is low; Panel has compressed, and mechanism can't walk any longer, and transmission is dumb.
3. weight capacity is poor.Because the conduction of interior weldering and welding gun mechanism must be fixed on the follower, but welding cable and conductive mechanism have constant weight, and must go deep in the pipe, make the follower distortion easily, also make its running mobility variation simultaneously.
4. the adjustment of eccentric throw direction must be stopped and be realized by adjusting welding gun.
5. the monofilament welding be can realize easily, but double wire welding and multifibres welding are difficult to realize.
Summary of the invention
Problem to be solved in the utility model is 1) the raising equipment accuracy of following the tracks of and the flexibility of equipment operation; 2) improve the weight capacity of equipment and the stability of equipment; 3) realize monofilament, mariages or multifibres welding easily; 4) realize not stopping to carry out the adjustment of eccentric throw.
The following technical scheme of the concrete employing of the utility model:
Weldering multifibres welding mechanism in a kind of spiral welded pipe, comprise welding arm, welding arm is provided with wire-feeding pipe, it is characterized in that, described wire-feeding pipe is flexible wire convey soft pipe, flexible wire convey soft pipe front end is provided with the wire feed head, also is provided with three-dimension adjusting mechanism on welding arm, and described wire feed head is fixed on the three-dimension adjusting mechanism.
Be provided with a plurality of flexible wire convey soft pipes, preferred 2-5.
Also be provided with motor fixing seat and wire feeding motor in flexible wire convey soft pipe rear end.
Compared with prior art, the beneficial effects of the utility model are:
(1) transmission accuracy height.
(2) stabilization of equipment performance height.
(3) weight capacity is strong.
(4) adaptive capacity is strong.An equipment can be realized monofilament weldering, Double Wire Welding, multifibres weldering.
(5) installation is easy to adjust.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-wire feed head, the flexible wire convey soft pipe of 2-, 3-welding arm, 4-three-dimension adjusting mechanism, 5-motor fixing seat, 6-wire feeding motor.
The specific embodiment
As shown in Figure 1, weldering multifibres welding mechanism in a kind of spiral welded pipe, comprise welding arm 3, welding arm 3 is provided with two flexible wire convey soft pipes 2, flexible wire convey soft pipe 2 front ends have wire feed head 1, it is fixed on and is arranged on the three-dimension adjusting mechanism 4, and flexible wire convey soft pipe 2 rear ends have motor fixing seat 5 and wire feeding motor 6.
