Technical field
The invention belongs to engine manufacturing technology field, be specifically related to a kind of titanium alloy material weld seam front gas shield dress
Put.
Background technology
The chemical property of titanium alloy is the most active.Test shows, the quick absorption hydrogen of titanium 300 DEG C, fast at 600 DEG C
Speed absorbs oxygen, and at 700 DEG C of quick absorbed nitrogens, and the main component of air is exactly oxygen and nitrogen, therefore reliable inert gas shielding is titanium
The key of alloy welding.In welding process, the form of blanketing with inert gas titanium alloy has two kinds at present: one is to fill in vacuum
Argon welding welds in cabin, and another kind is to fix special support cover on welding gun.Vacuum argon filling weldering cabin is limited by the device space, to product
The size Constrained of product, and in cabin, the operability of welding is poor, production efficiency is low；Special support cover method is used for automatic welding timeliness
Preferably, during manual welding, torr cover affects the sight line of welding gun work angle and welding operator to fruit, and due to manual instability
Make titanium alloy manual welding off quality, poor reliability.
As it is shown in figure 1, there is following defect in the most conventional titanium alloy manual argon arc welding torr cover structure: (1) to be protected in Shi Yonging
Welding gun must be kept when demonstrate,proving the protected effect welding operation of weld seam molten bath and heat affected area to be perpendicular to welding bead, thus affect welding behaviour
The sight line of author, is unfavorable for observing molten bath and wire feed operation, easily causes welding process fluctuation thus cause quality unstable；(2)
This mode guard space is short, is unsuitable for welding continuously.
Summary of the invention
In view of this, the invention provides a kind of titanium alloy material weld seam front gas shield device, it is possible to make titanium alloy
Manual welding is the easiest with the welding of other conventional material, and gas shield device also acts as heat radiation, reduces welding deformation simultaneously
Effect.
Realize technical scheme as follows:
A kind of titanium alloy material weld seam front gas shield device, including screw rod and two ventilation slide blocks；
Be connected by screw rod between two ventilation slide blocks, and by the nut that coordinates with screw rod regulate two ventilate slide blocks it
Between spacing；
It is provided with air inlet on described ventilation slide block, inside ventilation slide block, is machined with inlet channel along air inlet, two
Be machined with on the opposite face of ventilation slide block one group with upper vent hole group, often group passage group includes more than one passage, logical
Pore connects with inlet channel, often the axis of passage in group passage group on the cross section being perpendicular to inlet channel axis with
Radially distribute centered by the axis projections point of inlet channel.
Further, described titanium alloy material weld seam front gas shield device also includes alignment pin, and alignment pin is worn respectively
Cross the inlet port of two ventilation slide blocks.
Further, often group passage group includes that four passages, a passage are horizontal distribution, and its excess-three is ventilated
Hole is respectively 19 ° with the angle of the passage of horizontal distribution, 39 °, 64 °.
Further, the lower section of two ventilation slide block opposite faces is machined with outward-dipping inclined-plane.
Beneficial effect:
(1) in the present invention protect gas can be inputted by the ventilation slide block of welding gun both sides simultaneously, in welding process from
Air around weld seam is blown away by the front of weld seam, thus serves the effect of protection face of weld.
(2) present invention is covered with passage on ventilation slide block, and with rotation angle direction, protective gas is blown into welding
Region to be protected, after two ventilation slide block assemblings, its cross section composition is inverted " loudspeaker " type (angular range 40 °～50 °), in order to
In blowing argon to welding region and preferably holding together protective gas.
(3) present invention achieves gas shield device to separate with welding gun so that welding operation is not by gas shield device
Impact, can accomplish the flexible operating as normal welding.
(4) the ventilation slide block in the gas shield device of the present invention is placed in welding bead both sides, can absorb welding heat, plays scattered
Heat, the effect of reduction welding deformation.
(5) gas shield device of the present invention is applicable not only to the welding of straight welding line, it is possible to according to the knot of product to be welded
Structure does and " deforms " process accordingly, to adapt to the gas shield requirement of different structure, compares conventional argon arc welding torr cover motility and can
Extension has clear superiority.
