Abstract
The utility model is related to a kind of toolings for inhibiting flange welding deformation, including tooling platform, tooling platform includes pedestal and table top, pipe to be welded is arranged on the middle part of tooling platform, on pedestal several cylinders are provided with around welding pipe, the pistons end of cylinder is provided with briquetting, and fixing lug boss is provided on table top, and flange can be fixed in fixing lug boss by tabletting.The utility model is simple in structure, compact to design, easy to use, tabletting in fixing lug boss and cylinder can make flange generate lever moment, center weld region can obtain the reversible deformation power of bigger, reduce flange and the contraction distortion after pipe welding, improve the problem of postwelding planeness of flange is poor.
Description
Technical field
The utility model is related to a kind of toolings for inhibiting flange welding deformation, belong to welder technical field.
Background technology
Motor vehicle exhaust emission regulation it is increasingly strict, exhaust aftertreatment technology is the technical measures that must be used.And it encapsulates
Involved pipe end flange connection in the process, common processes are perforations on flange, and bolt is close to two flanges, is used between flange
Liner sealing, but the technical process is higher for the planarity requirements of end face of flange, the flange other end need with straight tube or
When welding, flange can lead to problems such as flatness overproof, because when flatness is inadequate, lead end cap because of sweating heat contraction distortion
Liner sealing is caused to fall flat, client is caused to use puzzlement.
Invention content
The purpose of this utility model is to solve the above-mentioned problems, to provide a kind of inhibition simple in structure, compact to design
The tooling of flange welding deformation.
The utility model adopts the following technical solution：A kind of tooling for inhibiting flange welding deformation, it is described including tooling platform
Tooling platform includes pedestal and table top, and pipe to be welded is arranged on the middle part of tooling platform, hold-down mechanism is provided on the pedestal,
Pipe can be pressed abd fixed on table top by the hold-down mechanism, if being provided with around pipe to be welded on the pedestal
A dry cylinder, the pistons end of the cylinder are provided with briquetting, and fixing lug boss is provided on the table top, and the briquetting can incite somebody to action
Flange is fixed in fixing lug boss.
Further, it is provided on the briquetting and positioning column corresponding on positioning pin.
Further, it is provided with support column between the pedestal and table top.
Further, the cylinder is four.
Further, the convex edge of table is provided with positioning pin corresponding with flange.
The utility model is simple in structure, compact to design, easy to use, and the tabletting in fixing lug boss and cylinder can make flange
Lever moment is generated, center weld region can obtain the reversible deformation power of bigger, reduce the contraction distortion after welding, improve weldering
The problem of rear flange flatness is poor.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the side view of the utility model.
Reference numeral：Tooling platform 1, pedestal 1-1, table top 1-2, support column 1-3, pipe 2, hold-down mechanism 3, cylinder 4, briquetting

Specific embodiment
Below in conjunction with attached drawing, the utility model will be further described.
As shown in Figure 1, a kind of tooling for inhibiting flange welding deformation, including tooling platform 1, tooling platform 1 include pedestal 1-1 and
Table top 1-2, pipe 2 to be welded are arranged on the middle part of tooling platform 1, and hold-down mechanism 3,3 energy of hold-down mechanism are provided on pedestal 1-1
It is enough that pipe 2 is pressed abd fixed on table top 1-2, several cylinders 4 are provided with around pipe 2 to be welded on pedestal 1-1,
The pistons end of cylinder 4 is worn to table top 1-2, and the pistons end of cylinder 4 is provided with briquetting 5, and it is convex that fixation is provided on table top 1-2
Platform 6, the edge of boss 6 are provided with and flange 7 can be fixed in fixing lug boss 6 with 7 corresponding positioning pin 8 of flange, briquetting 5,
Be provided on briquetting 5 with positioning column corresponding on positioning pin 8, be provided with support column between pedestal 1-1 and table top 1-2.
Method of work：Flange 7 to be welded is placed in the fixing lug boss 6 of tooling table top 1-2, the center of fixing lug boss 6
The middle part of alignment flange 7, the edge of flange 7 vacantly in fixing lug boss 6, adjust the piston of cylinder 4, make each 4 piston of cylinder
The positioning pin 8 at the briquetting alignment flange edge of end adjusts cylinder 4, and briquetting 5 is made to push 7 orchid of fixation, is started after the completion of fixed
It is welded, due to supported flange 7 energetically of briquetting 5 of cylinder 4, fixing lug boss 6 jacks up upwards, increases 4 clamping torque of cylinder,
Make 7 outer edge of flange by the pressure reversed with welding shrinking force, so as to inhibit welding contraction distortion.
