Abstract
The present invention is a kind of steel welding skew T tube manufacturing method, is a kind of for pipeline, and branch pipe is 30 °, 45 °, 60 ° of steel welding skew T pipe fitting with the angle of supervisor.Its technical characterstic is：The mold of skew T pipe fitting layout design manufacture is pressed first, then to the heating one end of branch pipe, after reaching predetermined temperature, start hydraulic press carries out hot extrusion to one end of branch pipe, gradually turned up in mold one end of branch pipe, the flanging face of formation is identical and angled with branch pipe axis with supervisor's profile, flanging face and branch pipe rounding off, part unnecessary on the outside of branch pipe flange is sliced off after shaping, in supervisor's predetermined position line opening, supervisor's opening size is more than branch pipe caliber size, after branch pipe flanging coordinates cutting with supervisor opening equidimension, carry out butt welding, branch pipe is welded together with supervisor, form a kind of main, the welding skew T pipe fitting of branch pipe intersecting lens rounding off.
Description
Technical field
The present invention is that a kind of hot extrusion forms branch pipe flange, branch pipe flange is used into butt welding by certain angle with supervisor again
Mode is welded, and a kind of steel welding skew T tube manufacturing method for being formed, it is a kind of for pipeline, branch pipe is with supervisor's
Angle is 30 °, 45 °, 60 ° of steel welding skew T pipe fitting.
Background technology
Current steel welding skew T pipe fitting is typically all to drive saddle with the intersecting lens of supervisor on supervisor, by branch pipe
Mouthful, then branch pipe is pressed the wire cutting of intersecting of branch pipe and supervisor, then branch pipe is welded with supervisor at the position of intersecting lens, form steel
System welding skew T pipe fitting.The skew T pipe fitting of this method manufacture particularly welds the class of formation in intersecting lens position stress concentration
Like angle welding, make fluid that impact is formed when the position is flowed through and breathe heavily stream.These safe handlings all to skew T pipe fitting are unfavorable,
Also increase fluid resistance.
The content of the invention
The present invention, first by one end outward flanging of branch pipe, makes the intersecting lens portion of branch pipe and supervisor using the method for hot extrusion
Circle of position degree of slipping over, then by branch pipe welding on supervisor.The mold of skew T pipe fitting layout design manufacture, the master of this mold are pressed first
Tube portion is identical with supervisor's external diameter of skew T pipe fitting, and manifold portion is identical with the branch bore of skew T pipe fitting, and is responsible for
Part is rounding off with manifold portion.Mold is fixed on the lower platform of hydraulic press, the steel pipe folder of angle then will be held successfully
On a hydraulic press at platform, the angle end of steel pipe is heated by Medium frequency induction coil, after reaching predetermined temperature, withdraw from sensing
Coil, starts hydraulic press and pushes steel pipe, the angle end of steel pipe is gradually turned up into mold and under the limitation of mold, is formed
Branch pipe flanging it is identical with supervisor's profile, and the axial direction in branch pipe flanging face is axially angled with branch pipe.After shaping
Branch pipe is taken out from mold, part unnecessary on the outside of branch pipe flange is sliced off, branch pipe is then buckled in supervisor's predetermined position line,
By drawn line in supervisor's upper shed, supervisor's opening size is more than branch pipe caliber size, the chi such as branch pipe flanging and supervisor opening
After very little cooperation cutting, butt welding is carried out, branch pipe is welded together with supervisor.This manufacture method can solve old-fashioned welding skew T
Pipe fitting forms impact when the position is flowed through and breathes heavily flow problem, and this system in intersecting lens position problem of stress concentration, and fluid
The method of making can also carry out radiographic inspection to weld seam, and solving old-fashioned welding skew T pipe fitting cannot carry out radiographic inspection to weld seam
Problem.
Brief description of the drawings
Fig. 1 is branch pipe flange shaping schematic view of the invention.
Fig. 2 is skew T schematic diagram of the invention.
Fig. 3 is skew T weld part bitmap of the invention
Specific embodiment
As shown in figure 1, pressing bevel arm piece layout design manufacture branch pipe mold, the hypomere of this mold and the master of skew T pipe fitting
Pipe external diameter is identical, and epimere is identical with the branch bore of skew T pipe fitting, between upper-lower section for rounding off and in axial direction into certain
Angle.
As shown in figure 1, mold 2 to be fixed on the lower platform 3 of hydraulic press, the branch pipe 4 of well cutting length and angle will be designed
Hydraulic press upper mounting plate 1 is clipped in, medium-frequency heating coil is placed at the predetermined heating in branch pipe angle end, started medium frequency equipment and add pipe end
Heat removes medium-frequency heating coil to predetermined temperature, and the upper cylinder half for starting hydraulic press pushes branch pipe 4, and the lower end of branch pipe 4 is in pressure
Gradually turned up with the presence of mold, that is, form a flanging and supervisor's profile identical branch pipe 4, and the supervisor of flange takes turns
Exterior feature and branch pipe into predetermined angle.According to different molds, this angle can be 30 °, 45 °, 60 ° or other angles, branch pipe and master
Guan Kewei is with footpath or reducing.For can not be one-time formed, then flange position be heated with acetylene rifle, and pushed in heating
Until shaping.The upper cylinder half for starting hydraulic press exits branch pipe 4, on the outside of the round and smooth excessive line of the flange of branch pipe 4 at about 50 millimeters, will
Unnecessary part is cut away, and branch pipe 4 is buckled in into supervisor 5（Fig. 2, Fig. 3）Predetermined position, along the profile cutting-up on the outside of the flange of branch pipe 4
Secant, then 5 upper sheds are being responsible for by this line of cut, then branch pipe 4 is docked welded together with being responsible for 5, ultimately form a branch
Pipe is the steel welding skew T pipe fitting of rounding off with supervisor's intersecting lens, as shown in Figure 2.
