Description

A Tooling for Restraining Flange Welding Deformation

technical field

The utility model relates to a frock for suppressing flange welding deformation, which belongs to the technical field of welding devices.

Background technique

As the automobile exhaust emission regulations become increasingly strict, the exhaust after-treatment technology is a technical measure that must be adopted. For the pipe end flange connection involved in the packaging process, the general process is that there are holes on the flange, the bolts make the two flanges tightly connected, and the flanges are sealed with gaskets, but this process has great impact on the flatness of the flange end face. The requirements are relatively high. When the other end of the flange needs to be welded with a straight pipe or end cover, the flange will shrink and deform due to welding heat, resulting in problems such as flatness out of tolerance, because when the flatness is not enough, the gasket seal cannot be reached. The expected effect caused troubles for customers.

Contents of the invention

The purpose of the utility model is to solve the above-mentioned problems, and to provide a simple structure and compact design tool for suppressing flange welding deformation.

The utility model adopts the following technical scheme: a tooling for suppressing flange welding deformation, including a tooling table, the tooling table includes a base and a table top, the round pipe to be welded is arranged in the middle of the tooling table, and the base is provided with a press The clamping mechanism can compress and fix the round pipe on the table. Several air cylinders are arranged around the round pipe to be welded on the base, and the piston ends of the air cylinders are provided with pressure blocks. A fixing boss is arranged on the table, and the pressing block can fix the flange on the fixing boss.

Further, the pressing block is provided with positioning posts corresponding to the positioning pins.

Further, a support column is provided between the base and the table top.

Further, there are four cylinders.

Further, the edge of the boss is provided with a positioning pin corresponding to the flange.

The utility model has the advantages of simple structure, compact design and convenient use. The fixed boss and the pressing piece on the cylinder can make the flange generate a lever moment, and the central welding area will get a larger anti-deformation force, which reduces the shrinkage deformation after welding and improves Solved the problem of poor flange flatness after welding.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings.

As shown in Fig. 1, a kind of tooling that suppresses flange welding deformation includes tooling table 1, and tooling table 1 includes base 1-1 and table top 1-2, and the round pipe 2 to be welded is arranged in the middle part of tooling table 1, and base 1-1 is provided with a pressing mechanism 3, which can press and fix the round pipe 2 on the table 1-2, and several cylinders 4 are arranged around the round pipe 2 to be welded on the base 1-1, The piston end of the cylinder 4 penetrates on the table 1-2, the piston end of the cylinder 4 is provided with a pressure block 5, the table 1-2 is provided with a fixed boss 6, and the edge of the boss 6 is provided with a corresponding flange 7. The locating pin 8, the briquetting block 5 can fix the flange 7 on the fixed boss 6, the briquetting block 5 is provided with a corresponding locating column on the locating pin 8, and the base 1-1 and the table 1-2 are provided with support column.

Working method: place the flange 7 to be welded on the fixed boss 6 of the tooling table 1-2, the center of the fixed boss 6 is aligned with the middle of the flange 7, and the edge of the flange 7 is suspended on the fixed boss 6 , adjust the piston of the cylinder 4 so that the pressure block at the end of the piston of each cylinder 4 is aligned with the positioning pin 8 on the edge of the flange, adjust the cylinder 4 so that the pressure block 5 presses down on the fixing flange 7, and start welding after the fixing is completed. The pressure block 5 of the cylinder 4 presses the flange 7 vigorously, and the fixed boss 6 lifts up, increasing the pressing moment of the cylinder 4, so that the outer edge of the flange 7 is subjected to a pressure opposite to the welding shrinkage force, thereby inhibiting welding shrinkage deformation .
