Abstract
A hard surfacing device for a small-bore steel tube, which comprises a spider, wherein a wire feeding machine set is arranged at the front end of the spider, and hard surface welding wires passes through the wire feeding machine set and are clamped and fixed in the welding gun at the front end of the wire feeding machine set, and is characterized in that the wire feeding machine set is horizontally arranged at the front end of the spider, a steel tube guide tube is mounted in the housing of the wire feeding machine set and extends out of the wire feeding machine set, the welding gun is fixed at the front end of the guide tube, and the hard surface welding wires respectively pass through the wire feeding machine set and the steel tube guide tube so as to be clamped in the welding gun. In the utility model the wire feeding machine set is arranged horizontally on the spider, and the steel tube guide tube is arranged in the wire feeding machine set, and the diameter of the steel tube guide tube is small enough for device to penetrate into the small bore steel tube with diameter smaller than 1m so as to carry out surfacing welding and prepare small-bore wear-resistant steel tube as well. The equipment is capable of surfacing welding for a steel tube with large bore.
Description
Technical field
The utility model relates to a kind of build-up welding apparatus, particularly a kind of small-caliber steel pipe hard-face overlaying welding device.
Background technology
Technique for overlaying is to utilize welding method to strengthen a kind of maintenance technique of machinery part surface, utilize this technology can change the chemical composition and the institutional framework of piece surface, improve its performance, prolong the service life of part, have important economic value, nowadays be widely used in industries such as metallurgy, mine, electric power, cement, iron and steel, oil.The wear-resistant steel pipe of present stage all adopts the technique for overlaying preparation, as shown in Figure 1, steel pipe 4 to be welded is taken turns on the board as for idler pulley, driving steel pipe 4 by the idler pulley wheel rolls, spider 1 front end of built-up welding machine is provided with line sending unit 2, stiff dough welding wire 3 is sent in the steel pipe 4 to be welded by line sending unit 2, carries out hard-face overlaying welding at steel pipe 4 inwalls.But the volume of the line sending unit in the existing build-up welding apparatus is bigger, and vertical the setting, when the steel pipe inwall is carried out built-up welding, to go deep in the steel pipe, so generally can only carry out built-up welding greater than the steel pipe more than 1 meter to diameter, and for the less steel pipe of bore, owing to can't enter steel duct, thereby can't carry out built-up welding.
Summary of the invention
Build-up welding apparatus can only carry out this problem of built-up welding greater than the steel pipe more than 1 meter to diameter in the prior art in order to solve, the utility model provides a kind of small-caliber steel pipe hard-face overlaying welding device, this build-up welding apparatus not only can carry out built-up welding to large diameter steel pipe, also is suitable for the built-up welding of small-bore steel pipe simultaneously.
The utility model technical scheme that adopts of dealing with problems is:
Small-caliber steel pipe hard-face overlaying welding device, include spider, the spider front end is provided with the line sending unit, and the stiff dough welding wire passes the line sending unit, and is clipped in the welding gun that is fixed on line sending unit front end, it is characterized in that: described line sending unit is horizontally installed on the spider front end, one steel pipe conduit is installed in the shell of line sending unit, and this conduit extends to outside the line sending unit, and catheter proximal end is fixed with welding gun, the stiff dough welding wire passes line sending unit, steel pipe conduit respectively, and is clipped in the welding gun.
The beneficial effects of the utility model: in this build-up welding apparatus the line sending unit is horizontally installed on the spider, and in the line sending unit, be provided with the steel pipe conduit, the diameter of steel pipe conduit is little, therefore can extend into diameter less than carrying out built-up welding in 1 meter the small-caliber steel pipe, prepares small-bore wear-resistant steel pipe.This equipment also can carry out built-up welding to bigbore steel pipe simultaneously.
Description of drawings
Fig. 1 is the structural representation of existing build-up welding apparatus;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Build-up welding apparatus as shown in Figure 2, small-caliber steel pipe hard-face overlaying welding device, include spider 10, spider 10 front ends are horizontally arranged with line sending unit 20, one steel pipe conduit 30 is installed in the shell of line sending unit 20, and this conduit 30 extends to outside the line sending unit 20, and conduit 30 front ends are fixed with welding gun 50, stiff dough welding wire 40 passes line sending unit 20, steel pipe conduit 30 respectively, and is clipped in the welding gun 50.
When treating welding steel pipe 60 and carrying out built-up welding, steel pipe 60 anti-putting to be welded are being pushed away on the roller board, steel pipe conduit 30 is deep in the steel pipe 60 to be welded, and steel pipe 60 is driven by the idler pulley wheel and rolls.When steel pipe 60 takes place to roll, be fixed on welding gun 50 heating powers of conduit 30 front ends, stiff dough welding wire 40 melted by heat and built-up welding are on steel pipe 60 surfaces.Stiff dough welding wire 40 constantly is sent in the welding gun 50 by line sending unit 20, and constantly is melted built-up welding on steel pipe 60 surfaces, until forming one deck wearing layer on steel pipe 60 surfaces.Wherein line sending unit 20 comprises a shell, be provided with transmission device in the shell, transmission device in the present embodiment is made up of one group of drive, and in the middle of stiff dough welding wire 40 was clamped in by this group delivery wheel, the drive of dependence both sides rotated in the same way welding wire 40 constantly is sent in the welding gun 50.In actual applications, the transmission device in the line sending unit also can be other forms.
In the utility model the line sending unit is horizontally installed on the spider, and is provided with the steel pipe conduit in the line sending unit, the diameter of steel pipe conduit is little, therefore can extend into diameter less than carrying out built-up welding in 1 meter the small-caliber steel pipe, prepares small-bore wear-resistant steel pipe.This equipment also can carry out built-up welding to bigbore steel pipe simultaneously.
