Description
Technical field
The utility model relates to a kind of tee tubes, more particularly, to a kind of supervisor's reducing tee.
Background technique
Tee tube is the common connecting tube of pipe-work, and the tee tube that heavy construction is used will often use reducer tee piece
To bear pressure.Notification number CN106051352B discloses a kind of large-scale pressure pipe to the processing engineering method of reducing tee pipe fitting, adopts
Use SA3P35P91 superhigh temperature resistant pipeline as reducing tee embryo material, the outer diameter of embryo material is greater than maximum in the middle part of reducing tee straight pipeline
Outer diameter, length of stock add required surplus according to the length of reducing tee straight pipeline, then blanking;Embryo material is put into preheating furnace, to
Blank is taken out when preheating temperature is between 1000 DEG C -1050 DEG C, embryo material is put into compacting tool set, material embryo flatten up and down,
Full of taking out after the molding for completing reducing tee when being bubbled with end in mold mouth to be pressed, the bubbling for being in charge of road junction is then cut away
Complete the blank of reducing tee;Increase slope cushion block in mold mouth, to inwardly curium is pressed into outside the mouth of straight pipeline and subtube
Row necking and duplicate necking compacting;The utility model, in controlled valve, alleviates the high pressure of big flow, avoids height in pipeline
The damage that pressure and erosion connect pipe, prolongs the service life.
The processing technology of above-mentioned tee tube is more complex, to straight pipeline and is in charge of by the slope cushion block that is arranged in mold mouth
Inwardly curium pressure carries out the compacting of necking outside the mouth in road, and repeated multiple times compacting completes reducing tee oral area after mold closes reality
Compacting.I.e. variable diameter is realized by specific mold, during necking, since entire tee tube tube body is all in mold
, the shape of tube body is easily controllable, but the variable diameter passage in pipe is since deformation extent difference of the material into pipe then can not be accurate
Control, the poor repeatability of product.
Utility model content
The purpose of the utility model is to provide a kind of supervisor's reducing tee, product is in mainly variable diameter knot at the both ends of straight tube

Long branch pipe;
(6) it suppresses: first blank being pressed into isometrical three-way shape with isometrical mold, it is under this state, corresponding on straight tube
The forming part of branch pipe is bubble structure;
(7) aperture aperture: is carried out using end of the plasma cutting machine to bubbling;
(8) continue to heat, drawing is carried out to branch pipe, branch pipe is pulled into target call length;
(9) it is responsible for rough turn: on lathe, being required supervisor's boring in place, then again according to the target inner hole of heavy caliber straight tube
Car owner's pipe both ends make supervisor both ends consistent at a distance from branch pipe, then enclose further along supervisor's outer wall vehicle one, the length and osculum of vehicle
The length of diameter straight tube keeps plus tolerance, and supervisor's wall thickness of vehicle and the wall thickness of straight pipe with small diameter keep plus tolerance;Then again vehicle and cone
The corresponding slope of shape pipe;
(10) pipe is reheated: is heated to 1050~1080 DEG C, keep the temperature 2-3min/mm;
(11) it flattens: the supervisor both ends of pipe after heating is flattened, the length of flattening is the length of straight pipe with small diameter and slope
The sum of degree, in variable diameter, helps to make the protection of the wall thickness of conical pipe and straight pipe with small diameter uniform then to billet reheat;
(12) blank of heat is put on three-way valve mold, special convergent circle is installed at the both ends of the corresponding supervisor of mold, it should
Convergent circle includes straight hole and bellmouth, and the shape of straight hole corresponds to the size of straight pipe with small diameter, and the shape of bellmouth corresponds to conical pipe
Size, when compacting, straight pipe with small diameter forms in straight hole, and conical pipe forms in bellmouth;
(13) after the mold of step 12 is ready, feeding compacting, compression moulding terminates;
(14) pipe after molding is heat-treated.
Preferably, the size after step (4) is flattened is 8-10mm smaller than desired bore.
Preferably, step (8) is using gasification furnace to heating of pipe blank, and when heating, which should be avoided, directly heats branch pipe, but
Straight pipe is heated.Using gasification furnace local heating pipe, in order to obtain longer branch pipe drawing length, heating is kept to supervisor,
Good ductility is kept, this setting allows branch pipe and supervisor to form relative temperature difference, to obtain longer branch pipe.
Preferably, supervisor's boring in step (9) refers in place by supervisor's both ends boring always to branch pipe, otherwise will affect threeway
Flow.
Specifically, step (11) is 1050 DEG C~1080 DEG C to the relation reheating temperature of blank.
In order to improve the mechanical performance of product, obdurability is improved, suitably reduction hardness, the heat treatment of setting steps (14) is
Heating is solid molten, heats product to 1050 DEG C, keeps 30-150min, then water cooling.
More reasonable way is, further includes pickling after step (14), polishing, flaw detection, ball blast, metalworking, is passivated, enters
Multiple working procedure in library, mark.
Compared with the prior art, the advantages of the utility model are: this application provides a kind of supervisor's reducing tee, life
