Description

Large-diameter steel pipe welding training tooling

Technical field

The utility model relates to a kind of welding training technical field of power industry, specifically a kind of large-diameter steel pipe Welding training tooling.

Background technique

As high parameter, large capacity, high efficiency, the New Heat-Resistant Steel of low pollution have been adopted extensively in large-size thermal power plant With, P92 steel, super304 stainless steel and other metal materials are widely applied in unit high-temperature surface and live steam piping, It is required for this purpose, the skills training for being directed to heavy caliber heat resisting steel welding personnel also proposed corresponding technique, in such welding training, If root layer weld seam is unprotected in welding process will cause a large amount of alloying component scaling loss in conjunction with air, make weld seam lose it is mechanical, The comprehensive performances such as chemistry.Therefore, it welds such steel grade and must make gas chamber and be filled with argon gas and its root layer weld seam is implemented to protect.It is existing There is the Chinese patent in technology such as Publication No. 203791818, weld seam argon filling is protected by making gas chamber, from certain journey It solves the problems, such as weldquality on degree, but still has shortcoming, if chamber volume is larger, increases argon gas usage amount, improve Training cost；Tooling heavy is not easy manufacture processing, it has not been convenient to training operation.

Summary of the invention

The utility model is a kind of structurally reasonable in order to overcome drawbacks described above to provide, small in size, reduces argon gas usage amount, Reduce the welding training tooling of training cost.

The technical solution adopted in the utility model is: a kind of welding training tooling of large-diameter steel pipe, it is characterized in that: including Support tube, upper spacer, lower clapboard and fixed device, upper and lower partition are circular slab, diameter and training to Coiling Welded Pipe Diameter is corresponding, and the upper end of support tube is arranged in the upper spacer, and lower clapboard is provided centrally with to be led to for what support tube passed through Hole, lower clapboard are mounted on the middle part of support tube by the through-hole, escape pipe are provided on upper spacer, be arranged on lower clapboard There is air inlet pipe, the lower end of support tube is arranged in fixed device, and fixed device setting passes through fixed dress in support tube lower end, support tube It sets and is attached with workbench.

It is detachable between the upper and lower partition and support tube as a kind of preferred structure of the utility model It connects, and is provided with the spring clip for limit on the support tube of the side of upper and lower partition.

Further, the fixation device includes fixed sleeving and bolt, and fixed sleeving one end is placed on support tube lower end Outside, the other end are placed on the bracket of workbench, and support tube is connect by fixed sleeving by bolt with the support of table.

The utility model is provided with diameter upper and lower partition corresponding with diameter of steel tube to be welded on support tube, which can It is respectively sleeved in two steel pipes to be welded on the outside of upper and lower partition and after the end of two steel pipes is connected to each other, two steel pipes and upper and lower A gas chamber is formd between partition, argon gas can be filled with gas chamber by air inlet pipe and be subjected to, can pass through in welding process Escape pipe carries out argon gas recycling, reduces pollution.The chamber volume that the utility model is formed is small, and the use of argon gas is greatly saved Amount, reduces training cost；The tool structure of the utility model is simple, light-weight, and processing easy to manufacture facilitates welding training to grasp Make；Set Demountable for upper and lower partition, can be replaced according to the steel pipe to be welded of different-diameter above and below every Plate is used with adapting to various sizes of steel-pipe welding training.

Detailed description of the invention

Fig. 1 is the schematic diagram of the utility model.

Specific embodiment

The utility model is further described now in conjunction with attached drawing, Fig. 1 is an embodiment of the present invention, including branch Stay tube 1, upper spacer 2, lower clapboard 3 and fixed device 4, upper and lower partition are circular slab, and diameter is with training to Coiling Welded Pipe 7 diameter is corresponding, and the upper end of support tube 1 is arranged in the upper spacer 2, and lower clapboard 3 is provided centrally with to be worn for support tube 1 The through-hole crossed, lower clapboard 3 are mounted on the middle part of support tube 1 by the through-hole, escape pipe 6 are provided on upper spacer 2, under Air inlet pipe 5 is provided on partition 3, the lower end of support tube 1 is arranged in fixed device 4, and support tube 1 passes through fixed device 4 and work Platform is attached.In the present embodiment, the fixation device 4 includes fixed sleeving and bolt, and fixed sleeving one end is placed on support 1 lower end outside of pipe, the other end are placed on the bracket of workbench, and fixed sleeving is connected support tube 1 and the support of table by bolt It connects, this sample tooling is just installed on the workbench, and workbench, which is mounted in, above the ground just carries tooling and to Coiling Welded Pipe 7 etc. The frame body of component.

Be detachable connection between the upper and lower partition and support tube 1 in the present embodiment, such as be threadedly coupled or Upper and lower partition, can also be fastened on support tube 1 by clamping etc. with nut, can also be in the support tube of the side of upper and lower partition Spring clip of the setting for limit on 1.

In use, will be first mounted on support tube 1 with the upper and lower partition of 7 internal diameter phase phase of steel pipe to be welded, then two Steel pipe 7 to be welded is successively placed on the outside of two partitions and is connected to each other the end of steel pipe 7 to be welded, is closely packed together, makes to be welded Socket part position is between two partitions, in this way, forming relatively closed gas chamber between two steel pipes 7 to be welded and upper and lower partition ?.The gas tube of argon gas air charging system is connect with 3 air inlet pipe 5 of lower clapboard, and the escape pipe 6 of upper spacer 2 is in off state, then It opens argon gas air charging system and argon gas is filled with to gas chamber, welding training can be carried out at this time and operated.Pass through pipeline in welding process Escape pipe 6 is connect with argon gas recyclable device, carries out argon gas recycling to reduce the pollution to environment.

The utility model has structure simple, light-weight, and processing easy to manufacture facilitates welding training to operate, and reduces training The characteristics of cost.
