Description
Technical field
The invention belongs to welding technology field, and in particular to a kind of assembled ultra-narrow gap MAG/MIG welds insulation nozzle.
Background technology
Melt pole electrical arc soldering method it is spontaneous it is bright since, apply nearly 90 years in industrial circle.It is molten to increase substantially
Change the productivity ratio and the quality of production of pole electrical arc soldering method, and while its production cost is greatly lowered, using narrow compole consumable electrode
Arc welding technology is most effective most efficient technological approaches.Carried from last century early sixties first by U.S.'s BATTLE institutes
Since going out " narrow gap welding Narrow Gap Welding " concept, the narrow-clearance submerged arc welding invented and narrow gap heated filament argon arc
Welding technology has a significant advantage of respective method, but the limitation of both special technologies also highly significant, and the former sweating heat is defeated
Enter very greatly, not significantly, the latter's productivity ratio is extremely low, and cost reduces not notable for section material economize on electricity reduces cost.Overcome both narrow
The above-mentioned limitation of gap technology simultaneously produces bigger solder technology progress, it is recognized that narrow gap MAG/MIG solder technology, the skill
Art since last century the seventies, in the world many countries especially Japan has put into substantial amounts of research in this field, but
40 years are in the past, so far industrial circle really succeed application country and industry it is very few, original of searching to the bottom
Cause, is not that the technical advantage of narrow gap MAG/MIG solder technology significantly and does not have across property progress, but narrow gap/
Ultra-narrow gap MAG/MIG welds the design and fabrication technology of welding gun, especially the high-temperature insulation technology and long-life technology of welding gun, extremely
The present fails to realize the breakthrough by can be premised on wide range of industrial applications.Prior art is such as：1.JP2001-179456A；2.JP2005-
211939；3. right, Zhang Fuju etc., a kind of inside/outside put multiple protective narrow gap/ultra-narrow gap weldering nozzle；4. European patent：
WO2012076750 (AI) -2012-06-14, Narrow Gap MIG/MAG Welding Torch.Above-mentioned prior art is concluded
Get up, there is following significant limitation：1. monoblock type multiple protective narrow gap/ultra-narrow gap welds nozzle, it is possible to resolve high temperature is exhausted
Edge problem and good metallurgical protection problem, but greatly heating inhomogeneities under working environment, easily cause nozzle cracking and
Failure, service life are short；2. most patents are non axial supply, the uniform flow without nozzle inner walls and effect of contraction, are both difficult to realize
There is circumferential hot compression effect to electric arc and reliable laminar flow protective effect can be carried out to pyrometallurgy area.
The content of the invention
The present invention is mainly addressed by following technical proposals to the limitation of above-mentioned prior art：
A kind of assembled ultra-narrow gap MAG/MIG welds insulation nozzle, it is characterised in that include being installed on by sunk screw
The left insulation strip in the left side of torch body end ignition tip, be respectively arranged in torch body end middle part and right part before and after insulate
Plate and right insulation strip；One end upper width center of left insulation strip and right insulation strip is provided with a cylinder boss, for welding gun sheet
Position and prevent revolution, other end widthwise central to be provided with the screw hole for installing sunk screw when the bottom of body is assembled；Before and after described
Insulation board includes front insulation board and rear insulation board, and front insulation board is identical with rear panel structure, is en plaque profile, insulation board
Left and right sides top be respectively provided with the tenon structure of an evagination；Left insulation strip and right insulation strip are rod structure, and there is evagination one end
Tenon structure, the upper outside of evagination tenon structure are provided with two recessed grooves, and the chase groove is used for the outer tenon knot of insulation board in front and back
Structure here is located by connecting.
In a kind of above-mentioned assembled ultra-narrow gap MAG/MIG welderings insulation nozzle, it is described before and after insulation board, left insulation strip and
Right insulation strip is ceramic material and makes.
Therefore, the invention has the advantages that：1. nozzle is improved to 4 assembleds by traditional monoblock type, and local is very big
Operational difference and cause cracking failure failure be greatly lowered, the nozzle operation life-span increases substantially；2. nozzle long-term work ring
Under border, intensification highest region is located at the insulation board in front and back at ignition tip position, manufactures and designs and before and after's insulation board is given when installing
The free stroke of permission, during work, the strong heat radiation of electric arc and convection current are to during insulation heating in front and back, complete during its flatulence of heat type state
Freely extend completely without rigid constraint ground, otherwise freely can shorten, this is the major reason that its working life is increased substantially；3. by
Simple in component profile, manufacturing process is easier to ensure that dimensional accuracy and workmanship, and manufacturing cost is lower.
