Abstract
The utility model relates to an online gas protection and cooling device for weld joints of welded pipes, which comprises a copper pipe. The online gas protection and cooling device is characterized in that the copper pipe is connected to the rear of a welding chamber of a production line, a gas inlet pipe is disposed on the copper pipe and connected with a protective gas supply device, a spray pipe is arranged at the tail end of the copper pipe, a plurality of small holes are arranged on the inner wall of the spray pipe, and a water inlet pipe is connected onto the spray pipe and communicated with the small holes on the inner wall. The online gas protection and cooling device for weld joints of welded pipes has the advantages of simple structure, novelty, practicality and convenience in operation. As proved by practice, the online gas protection and cooling device not only isolates the weld joints of the welded pipes from the air and avoids oxidization, but also realizes timely, rapidly and uniformly cooling effect for the welded pipes, improves production condition for a follow-up working procedure, and lays the foundation for improving quality of the weld joints.
Description
Technical field
The utility model relates to online gas shield of a kind of welded tube weld seam and cooling device.
Background technology
When producing pipe with welding, at first need band is formed bending, weld then.But, because the welding of welded tube is carried out fast, therefore just finished the weld seam of welding under the condition of high temperature, also need there be a high temperature to continue the process and the time of spreading on the one hand, with the further quality of improving weld seam; On the other hand, in a single day the weld seam under the condition of high temperature has run into airborne oxygen, and the surface will produce oxidation (presenting oxidation tint) phenomenon.The oxidation of weld seam except the appearance that has influence on welded tube, also will have influence on the quality of weld seam and even the service life of welded tube.This is a ubiquitous a pair of contradiction during welded tube is produced.
In addition, welded tube is produced on tinuous production mostly.After welded tube is finished welding, and then also has multiple tracks manufacturing process.Therefore, for the weld seam under the condition of high temperature, should be after the diffusion that gives certain hour, must be in time, cooled off fast and equably.Not so, will be to follow-up operation, as lubricated, the condition that heat treatment is initial of: first size rolls system and relevant operation etc., bring many adverse influences.
Therefore; during welded tube is produced; hope can have a kind of both effective online safeguard measures of the weld seam of secluding air; can in time realize welded tube device quick, that evenly cool off again; so that weld seam can avoid taking place high-temperature oxydation when obtaining High temperature diffusion, and by timely, quick and cooling uniformly; improve the working condition of subsequent handling, guarantee the workmanship of welded tube thus.
Summary of the invention
The purpose of this utility model is to solve in the prior art existing the problems referred to above when producing pipe, and online gas shield of a kind of welded tube weld seam and cooling device are provided.The utility model designs the online protection cooling device of a kind of weld seam gas; comprise a copper pipe; it is characterized in that: after the welding booth of production line, be connected with a copper pipe; one air inlet pipe is arranged on copper pipe; air inlet pipe connects the protective gas feeding mechanism, at the copper pipe end one shower is arranged, and a plurality of apertures are arranged on the inwall of shower; tap into water pipe on the shower, water inlet pipe is communicated with a plurality of apertures on the inwall.The utility model has the advantages that simple in structure, Nover practical, easy to operate.Facts have proved: the use of this device, both made the weld seam of welded tube completely cut off air, avoided oxidation, make again that welded tube has obtained in time, cooling effect fast and equably, for subsequent handling has been improved working condition,, lay a good foundation for the raising of weldquality.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is made detailed operation instruction.
The specific embodiment
Comprise a copper pipe 1 among the figure; it is characterized in that: after the welding case 7 of production line, be connected with a copper pipe; one air inlet pipe 2 is arranged on copper pipe; air inlet pipe connects protective gas feeding mechanism (not drawing among the figure); at the copper pipe end one shower 3 is arranged; a plurality of apertures 4 are arranged on the inwall of shower, tap into water pipe 5 on the shower, water inlet pipe is communicated with a plurality of apertures on the inwall.
The band steel is configured as the pipe that has slit through shaping machine set, and pipe slit (being connected with protective gas) in the welding case welds welded tube 6 through being welded into of automatic welder(welding machine).At this moment, the weld seam of welded tube is still located the condition of high temperature, when it goes out to weld case, must and enter subsequent handling through device of the present utility model.When welded tube enters the copper pipe of device of the present utility model; the air inlet pipe of copper pipe top connection protective gas source of the gas has made and has been full of protective gas in the pipe; weld seam under the condition of high temperature just continues diffusion and welding quality is improved, and avoided the high-temperature oxydation of weld seam effectively under the protective gas good protection.When welded tube passed through the shower of copper pipe end, the aperture that is evenly distributed on the shower inwall just sprayed cooling in all directions to welded tube, made welded tube obtain in time, cool off fast and uniformly.
Characteristics of the present utility model are: simple in structure, and Nover practical, easy to operate. Facts have proved: the use of this device, both made the weld seam of welded tube completely cut off air, avoided oxidation, make again that welded tube has obtained in time, cooling effect fast and equably, for subsequent handling has been improved working condition, for the raising of weldquality, lay a good foundation.
