Technical Field
The utility model relates to a pressure vessel makes the field, especially relates to a head center flange dress welds auxiliary fixtures.
Background
In the manufacturing process of the pressure vessel, the pipe connecting flange is often required to be welded on the ellipsoidal head and the spherical head. In the existing welding process, saddle welding or shielded metal arc welding is carried out along with the pressure bearing of the seal head due to the pressure action of the pipe connecting flange on the seal head, the port of the seal head deforms to different degrees in the process, so that a plurality of welding defects (welding beading, cold cracks, reheating cracks and the like) exist in the welding process, and the levelness and the verticality of the end face of the pipe connecting flange can be influenced due to the deformation, so that the welding quality is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a head center flange dress welds auxiliary fixtures is provided, its pressure-bearing deformation through improving the port that prevents the head improves welding quality.
In order to solve the problems, the utility model discloses an auxiliary tool for welding a flange of a central connecting pipe of a seal head, which comprises a chassis, a stand column arranged at the central position of the chassis and a top plate arranged at the top of the stand column; a plurality of bolt holes for being in bolt connection with mounting holes on the pipe connecting flange are formed in the top disc, and the height of the stand column is adjustable; when the welding head is used, the pipe connecting flange is fixedly arranged on the top disc, and the to-be-welded part at the edge of the pipe connecting flange corresponds to the to-be-welded part of the central opening of the sealing head.
Preferably, the top tray comprises two support plates which are stacked on the top of the upright post, and the two support plates are both in a long strip shape and are arranged in a cross shape.
Preferably, the upright column comprises a large sleeve with the bottom arranged on the base plate and a small sleeve with the top arranged on the top plate, and the lower part of the small sleeve is arranged inside the large sleeve in a penetrating manner and is adjusted in height through a bolt and a bolt hole which are matched with each other.
Preferably, the top of the upright column is connected with the bottom of the top disc through a backing plate.
Preferably, the bolt holes on the top disc are uniformly distributed on the circumference and are distributed in a plurality of circles in the radial direction.
Compared with the prior art, the utility model has the following advantage:
in the utility model, the auxiliary tool comprises a chassis, a stand column and a top plate, and has simple structure and convenient use; when the welding head is used, the pipe flange is fixed on the top disc, the edge of the pipe flange is made to correspond to the central hole of the end socket, and the position to be welded is made to correspond to the central hole of the end socket.

Detailed Description
The embodiment of the utility model provides a head center flange dress welds auxiliary fixtures, its main pipe flange welding process who is applied to head center (being head peak) trompil department. The auxiliary tool mainly comprises a base plate, an upright post arranged at the central position of the base plate and a top plate arranged at the top of the upright post; the top plate is provided with a plurality of bolt holes for being connected with the mounting holes on the connecting pipe flange through bolts, and the height of the upright post is adjustable.
When the device is used, the pipe flange is fixed on the top disc through the bolt connection, then the position to be welded at the edge of the pipe flange corresponds to the position to be welded of the central hole of the seal head through the height adjusting function of the upright column (of course, the correspondence can also be realized through the fixing of the pipe flange and the moving of the seal head), and finally the welding work of the two positions to be welded is carried out according to the conventional method. In the process, the weight of the pipe connecting flange is borne by the auxiliary tool, and the end socket does not bear the pressure of the pipe connecting flange.
Specifically, the top plate can be a circular plate or a square plate, bolt holes for fixing the pipe connecting flange are uniformly distributed on the circumference (several circles of bolt holes can be arranged in the radial direction to adapt to pipe connecting flanges with different diameters), the number is set according to the situation, and the pipe connecting flange can be stably fixed. Certainly, for save material, the top dish can also be like 1~2 be the setting of cross form, and top dish 1 specifically can be two for being long banding extension board 5 promptly, and both are the cross and stack at the stand top, offer the bolt hole 6 that is used for fixed flange of connecting pipe on the extension board 5.
Referring to fig. 1-2, the upright column comprises a large casing 2 with the bottom arranged on a chassis 1 and a small casing 3 with the top provided with a top plate, wherein the lower part of the small casing 3 is arranged inside the large casing 2 in a penetrating way and the height adjustment is realized through a bolt and a bolt hole (not shown in the figure) which are matched with each other. In order to realize fine adjustment of the height, the arrangement density of the bolts and the bolt holes can be appropriately larger, and of course, other commonly used height-adjustable realization means in the mechanical field can also be adopted.
The top of stand links up through backing plate 4 realization with the bottom of top dish, and backing plate 4 welding is at little sleeve pipe 3 tops, and the top dish is fixed through the bolt and the bolt hole realization that the cooperation was used with backing plate 4.
In the actual manufacturing process, the overall height of the upright post, the diameter/length of the top disc and the position of the bolt hole are adjusted according to end sockets and pipe connecting flanges with different specifications; the verticality among the upright post, the base plate and the top plate is ensured; the parts may be made of steel and, in addition to the above mentioned bolted connections, other connections may be made by welding.
The technical scheme provided by the utility model is introduced in detail above. The principles and embodiments of the present invention have been explained herein using specific examples, and the above descriptions of the embodiments are only used to help understand the structure and core ideas of the present invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.
