Abstract
The invention belongs to welding fields, and in particular to a kind of tooling for wingtip cover welding forming.The problems such as wingtip cover is metal plate weldment, bad using back of weld incomplete fusion existing for argon tungsten arc process and back-welding shape.The present invention provides a kind of tooling for wingtip cover welding forming, the tooling include bottom plate and on bottom plate activity installation sharp camber block and fixed installation blunt camber block, the edge of the sharp camber block is consistent with the theoretical shape of trailing edge, and the edge of the blunt camber block is consistent with the theoretical shape of the leading edge of a wing；It is respectively provided with the pipeline of conveying inert gas in the inside of the sharp camber block and blunt camber block, there are several gas holes in the welding region of the sharp camber block and blunt camber block, gas hole is connected to pipeline.It solves since the intracavitary ventilation protection of narrow type is insufficient and uneven, the problem and weld seam unevenness of caused quality of weld seam molding difference accumulate the uncontrollable problem of shape.
Description
Technical field
The invention belongs to welding fields, and in particular to a kind of tooling for wingtip cover welding forming.
Background technique
Wingtip cover is metal plate weldment, bears aerodynamic loading and oscillating load, therefore requires weld seam need to be through fluorescent Liquid penetrant testing
Free from flaw, it is bad using back of weld incomplete fusion existing for argon tungsten arc process and back-welding shape the problems such as, it is special to need design
Type tooling solves the problems, such as quality of weld seam molding.
Summary of the invention
The technical problems to be solved by the present invention are: on wingtip cover type chamber two arc-shaped welding seams forming quality problem.
A kind of tooling for wingtip cover welding forming, the tooling include bottom plate and the sharp arc that activity is installed on bottom plate
The edge of the blunt camber block of type block and fixed installation, the sharp camber block is consistent with the theoretical shape of trailing edge, the blunt arc
The edge of type block is consistent with the theoretical shape of the leading edge of a wing；Conveying is respectively provided in the inside of the sharp camber block and blunt camber block
The pipeline of inert gas has several gas holes, gas hole and pipeline in the welding region of the sharp camber block and blunt camber block
Connection.
Pipeline in the sharp camber block and blunt camber block has what is be connected to external air source to connect mouth.
The gas hole is uniformly distributed and size is consistent.
Diameter d:1mm≤d≤2mm of the gas hole.
The sharp camber block is fixed on movable block, a pair of of limited block is equipped in movable block two sides, on the bottom plate
It is also equipped with screw thread block set, threaded mandrel is connected to the end of the movable block after the screw thread block set.
The utility model has the advantages that solving since the intracavitary ventilation protection of narrow type is insufficient and uneven, caused quality of weld seam molding
The problem and weld seam unevenness of difference accumulate the uncontrollable problem of shape.

Specific embodiment
A kind of tooling for wingtip cover welding forming, the tooling include bottom plate 5 and on bottom plate 5 activity installation it is sharp
Camber block 1 and the blunt camber block 2 being fixedly mounted, the edge of the sharp camber block 1 is consistent with the theoretical shape of trailing edge, described
The edge of blunt camber block 2 and the theoretical shape of the leading edge of a wing are consistent；Distinguish in the inside of the sharp camber block 1 and blunt camber block 2
With conveying inert gas pipeline, the welding region of the sharp camber block 1 and blunt camber block 2 have several gas holes 13,
14, gas hole 13,14 is connected to pipeline.
Pipeline in the sharp camber block 1 and blunt camber block 2 has what is be connected to external air source to connect mouth 3,4.The air blowing
Hole 13,14 is uniformly distributed and size is consistent.Diameter d:1mm≤d≤2mm of the gas hole 13,14.
The sharp camber block 1 is fixed on movable block 7, a pair of of limited block 6 is equipped in 7 two sides of movable block, at the bottom
Screw thread block set 8 is also equipped on plate 5, threaded mandrel 9 is connected to the end of the movable block 7 after the screw thread block set 8.
Sharp camber block 1 described in the sheet metal component press-type block type face pressure Qu Zhiyu cut out and blunt camber block 2 are conformed to can not
See gap, and corresponding groove cuts off clout on press-type block, after being installed in place, carries out spot welding, then be passed through inert gas, carry out two
The argon arc welding of weld seam, after welding, molding to be cooled is finished, and closes inert gas, and rotation threaded mandrel 9 is by sharp camber block
It inside contracts, product is removed.
