Description
Technical field
The present invention relates to a kind of hot wire welding welding gun technical field.
Background technology
With continuing to develop for welding technique, people the developing goal of welding technique is concentrated mainly on it is following some：1、
Improve welding procedure and method to adapt to the new material continued to bring out；2nd, welding efficiency is improved to adapt to the manufacture skill of high speed development
Art；3rd, stability of the mechanical automation ability of lifting welding technique to liberate labour and ensure welding quality.Welding technique
It is developed so far, using more generally gas metal-arc welding, many wire bonds, compound hot type welding method.Several method is each
There are pros and cons.Wherein being combined hot type welding method is combined by the mode of heating of a variety of form of heat, is increased thermal weld stress, is carried
The efficiency of height welding.But existing compound hot type welding method welding efficiency has much room for improvement, and welding quality is also not ideal enough, Shang You
It is many to need to improve and improved place.
The content of the invention
The invention aims to solve the not enough high there is provided one kind of above-mentioned existing compound hot type welding method presence
Frequently pre-heated hot wire welding welding gun, to improve welding efficiency and welding quality.
The purpose of the present invention is achieved through the following technical solutions：
A kind of radio-frequency preheating formula hot wire welding welding gun, including gun body and high frequency heating system, wherein, gun body include blast tube and
The ignition tip in blast tube is located at, below the ignition tip in blast tube, is coaxially provided with what is be connected with high-frequency heating control system
High-frequency heating helix tube, the top and bottom of high-frequency heating helix tube connect high-frequency heating helix tube water inlet pipe respectively and high frequency adds
Hot helix tube outlet pipe, recirculated cooling water is flowed into by high-frequency heating helix tube water inlet pipe, by high-frequency heating helix tube outlet pipe stream
Go out.
The radio-frequency preheating formula hot wire welding welding gun of the present invention is compared with existing welding gun, due to being provided with high frequency heating system,
In the presence of high frequency high current, the strong flux of high-frequency heating helix tube polarization instantaneous variation, through high-frequency heating spiral shell
The direction opposite with heated current produces vortex flow inside the welding wire of coil, welding wire temperature is increased rapidly, and welding wire is entering weldering
Very high temperature is heated up before connecing electric arc, the heat needed for welding wire reaches fusion temperature is less so that in identical weldering
Connect under normality condition, with higher deposition efficiency, and then be greatly enhanced welding efficiency.In addition, action of alternating magnetic field is in weldering
Molten bath is connect, agitaion can be produced to it, crystal grain thinning is reached, improves the purpose of seam organization, the quality of weld seam is improved.This hair
Bright welding gun construction is reasonable, easy to maintenance, also has energy-conserving and environment-protective using high-frequency heating, the features such as the efficiency of heating surface is high.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Radio-frequency preheating formula hot wire welding welding gun as shown in Figure 1, including gun body and high frequency heating system two parts, wherein, rifle
Body is made up of blast tube 2 and the ignition tip 4 being located in blast tube 2；Below ignition tip 4 in blast tube 2, it is coaxially provided with and height
The high-frequency heating helix tube 3 that frequency heating control system is connected and is controlled by it, the top and bottom difference of high-frequency heating helix tube 3
High-frequency heating helix tube water inlet pipe 31 and high-frequency heating helix tube outlet pipe 32 are connected, recirculated cooling water is by high-frequency heating helix tube
Water inlet pipe 31 is flowed into, and is flowed out by high-frequency heating helix tube outlet pipe 32.Welding wire is sent into by wire feed system 1 and through gun body, from
Ignition tip 4 and the center of high-frequency heating helix tube 3 are passed through, and wire tip stretches out the segment distance of nozzle 2 one.
The present invention starts the source of welding current and high frequency heating system, due to welding wire in use, assemble metalwork to be welded first
5 are in contact with ignition tip 4, and welding wire 5 contacts the electric arc that ignites in a flash of workpiece, synchronizes, protective gas is constantly conveyed, by
Nozzle 2 is output in arc atmosphere, it is ensured that welding arc is not disturbed by outside air.Further, since welding wire 5 is from high-frequency heating
Passed through in helix tube 3, and high-frequency heating helix tube 3 is by high frequency heating system control, so that in high-frequency heating helix tube 3
In the heating temperature of welding wire 5 rise, so allow for welding wire 5 enter welding arc before be at very high temperature, in phase
With under welding current and voltage, it welds deposition efficiency and is much larger than traditional welding gun not processed, and then improves welding effect
Rate.Because high-frequency heating helix tube water inlet pipe 31 and high-frequency heating helix tube outlet pipe 32 are stretched out in the two ends of high-frequency heating helix tube 3,
During high-frequency heating helix tube 3 does to welding wire 5 and heated, recirculated cooling water is endlessly by high-frequency heating spiral
Water inlet tube pipe 31 is flowed into, and is flowed out by high-frequency heating helix tube outlet pipe 32 so that the temperature of high-frequency heating helix tube 3 is in relative
Relatively low level, it is ensured that its service life.As welding wire 5 is endlessly sent into by wire feed system 1, in the guarantor of protective gas
Under the pre- heat effect of shield and high-frequency heating helix tube 3, welding arc melts metal to be welded, and welding gun is moved forward, weld metal warp
Cross fusing --- cooling procedure and form complete weld seam, realize the connection of metalwork to be welded.Due to being in high-frequency heating helix tube 3
High frequency alternating current is passed through, so the magnetic field of alternation can be produced in high-frequency heating helix tube 3, according to Lenz's law, alternation
Magnetic direction is along high-frequency heating helix tube axis direction, the i.e. feeding direction of welding wire 5, and it is pointed to the change in alternating current direction
Change.Alternating magnetic field can produce agitaion to molten bath, can reach crystal grain thinning, improve the effect of seam organization.
