Abstract

The utility model provides an adjustable build-up welding apparatus with two purposes, which is characterized in that the length of a welding gun rod [2] between an electricity conduct mouth [3] on a welding gun mechanism [1]and a wire feeder [8] is increased, and a coercive cooling system is arranged on the electricity conduct mouth [3] body; the utility model is suitable for the build-up welding of the inner and the outer surfaces of cylinders and cones which are provided with various diameters and are forms in a submerged arc build-up welding and an open arc build-up welding; the utility model solve the problems that the electricity conduct mouth is melted because of high temperature, residues are sprayed to block the electricity conduct mouth, and the build-up welding work is interrupted; the utility model has the advantages of having convenient operation, improving and enhancing operating environment of operators and labor intensity and enhancing operating efficiency.

Description

Adjustable dual purpose reactor welder

The utility model relates to a kind of build-up welding apparatus, and particularly a kind of welding gun pole length lengthening and ignition tip body are provided with the build-up welding apparatus of pressure cooling system, are applicable to submerged arc and open arc built-up welding.

The structure of the submerged arc welding machine that present most of factory uses all is that the ignition tip of wire-feed motor and welding gun mechanism is the very near one of distance.As the mobile built-up welding of need position, whole welding machine all need move.As little, when welding, just can't operate the long enterprising windrow of the interior ring of cylindrical shell of weld seam at diameter.Because built-up welding continuously causes the workpiece heating, the operator can't enter in the cylindrical shell and operate.Because wire-feed motor and ignition tip distance are too near, when built-up welding for a long time, higher workpiece temperature is damaged the motor of wire-feed motor easily.The high temperature that electric arc produced causes ignition tip heating until fusing, or ignition tip is blocked makes built-up welding work interruption because of the dry slag that splashes sticks in the ignition tip end.

For overcoming the above problems, each welding all will be to different orbit and the supports of various workpiece designs.Therefore, this welding machine only is adapted to flat board or the diameter submerged arc overlay welding than the imperial palace ring, and adjusts frequently, and operating difficulties can't carry out continuous built-up welding.

The purpose of this utility model is that a kind of improved adjustable dual purpose reactor welder will be provided, this device is applicable to submerged arc and open arc built-up welding, be applicable to the cylindrical shape of various diameters, conical inside and outside surface overlaying also can prevent the ignition tip over hot melting in the weld deposit process and the dry slag that splashes effectively.

The purpose of this utility model is achieved in that the welding gun bar lengthening of welding gun mechanism and can adjusts according to Workpiece length.The ignition tip of welding gun mechanism is contained in the downward end of welding gun rod bending, and wire-feed motor then is contained in away from the other end of ignition tip at the welding gun bar.Thereby solved the operational issue of ring in the cylindrical shell of minor diameter, long weld seam.The operator need not to enter in the cylindrical shell and operates, and has alleviated labour intensity.Simultaneously when the open arc built-up welding since wire-feed motor away from the high temperature that ignition tip produced, its motor is not fragile, has prolonged the life-span.Because operator's arc of recess light is far away, has also avoided the infringement of pernicious gas to human body.

The body of ignition tip is provided with pressure cooling system.Prevented the continuous high temperature when built-up welding and made the ignition tip heating cause the problem that wire feed interrupts and built-up welding work is interrupted because of the dry slag that splashes blocks until fusing or ignition tip end.

Be further described below in conjunction with drawings and Examples.

Figure one is the adjustable dual purpose reactor welding machine that the utility model proposes.

Figure two is profiles of sequence number 1 among the figure one.

Figure three is submerged arc welding machines of known technology.

With reference to figure one, welding gun bar [2] extended and do to be in line and the arc-shaped bend shape.Welding gun mechanism [1] is installed in the crooked downward end of welding gun bar [2], and wire-feed motor [8] is installed in an end of welding gun bar straight line.Welding tractor [11] is provided with pressure cooling system [10].Drive back and forth movement by welding tractor [11] during built-up welding and carry out built-up welding, the operator only need start built-up welding operating system can realize continuous built-up welding.Solder flux bucket [9] is angled with the face of weld, delivers to the welding gun end by the flux delivery pipe, the problem that solder flux can't add when having solved the minor diameter built-up welding.

With reference to figure two, a cooling jacket [4] is installed on welding gun bar and ignition tip.Cooling jacket [4] has cannelure and seal cover, and seal cover is provided with water inlet pipe [5] and outlet pipe [6].This cannelure is in order to logical recirculated cooling water.When built-up welding, cooling water makes ignition tip unlikely mistake thermal expansion and wired, and the while also makes the dry slag that splashes peel off voluntarily.But through forcing ignition tip long time continuous working in practical operation of cooling, increase service life.

Wire convey soft pipe [7] is in remote wire feed process, because the effect of guiding and eliminating welding wire surface medicinal powder and dust is played in the effect of spring.

This device operation tube is just flexible, and operator's working environment and labour intensity improve and improves, and have reduced maintenance cost, have improved operating efficiency.
