Abstract
The invention relates to a manufacturing technique of a steel welded lateral tee fitting applied to a pipe; an included angle between a branch pipe and a main pipe is 30 degrees, 45 degrees or 60 degrees. The manufacturing technique is technically characterized in that a jig is designed and manufactured according to a lateral tee fitting drawing, one end of the branch pipe is heated, a hydraulic press is started to thermally extrude one end of the branch pipe after the preset temperature is reached, one end of the branch pipe is gradually turned out in the jig, the surface of an turned-out edge formed and the outline of the main pipe are equal, a certain angle is formed between the turned-out edge and the axis of the branch pipe, the surface of the turned-out edge smoothly transits to the branch pipe, the outer excess part of the turned-out edge of the branch pipe is cut off after forming, the preset portion of the main pipe is scribed and provided with an opening, the branch pipe and the main pipe are welded together, and the novel welded lateral T fitting with smooth transition lines of intersection of the main and branch pipes is formed.
Description
Technical field
The present invention is that a kind of hot extrusion forms arm flange, arm flange welded by certain angle with supervisor again, and a kind of Novel steel welding skew T pipe fitting manufacturing technology forming, be a kind of for pipeline, arm and supervisor's angle is the steel welding skew T pipe fitting of 30 °, 45 °, 60 °.
Background technology
Current steel welding skew T pipe fitting is all generally on supervisor, by arm and supervisor's intersecting lens, opens saddle port, then arm is pressed to arm and supervisor's intersecting lens cutting, again arm is welded at the position of intersecting lens with supervisor, form steel welding skew T pipe fitting.The skew T pipe fitting that this method is manufactured is concentrated at intersecting lens position stress, and the similar angle welding that particularly welding forms forms fluid and impacts and breathe heavily stream when flowing through this position.These are all unfavorable to the safe handling of skew T pipe fitting, have also increased fluid resistance.
Summary of the invention
The present invention adopts the method for hot extrusion, first by one end outward flanging of arm, makes arm and supervisor's intersecting lens position round and smooth excessively, then by branch pipe welding on supervisor.First press the mold that skew T pipe fitting layout design is manufactured, supervisor's part of this mold is identical with supervisor's external diameter of skew T pipe fitting, and a tube portion is identical with a bore of skew T pipe fitting, and supervisor's part is rounding off with a tube portion.Mold is fixed on to the lower platform of hydraulic press, then the steel pipe of holding angle successfully is clipped in to hydraulic press upper mounting plate place, by Medium frequency induction coil, the angle end of steel pipe is heated, reach after predetermined temperature, withdraw from induction coil, start hydraulic press steel pipe is pressed down, make the angle end of steel pipe enter mold and turn up gradually under the restriction of mold, the arm flanging forming is identical with supervisor's profile, and the axial and arm of arm flanging face is axially angled.After moulding, arm is taken out in mold, slice off unnecessary part outside arm flange, then arm is buckled in to the line of supervisor's predetermined position, press drawn line being responsible for upper shed, then arm and supervisor are welded together.This manufacturing technology can solve old-fashioned welding skew T pipe fitting in intersecting lens position problem of stress concentration, form when flowing through this position with fluid and impact and breathe heavily flow problem, and this manufacturing technology can also carry out radiographic inspection by butt welded seam, solved the problem that old-fashioned welding skew T pipe fitting cannot butt welded seam carries out radiographic inspection.

Fig. 2 is skew T schematic diagram of the present invention.
Fig. 3 is skew T weld part bitmap of the present invention
The specific embodiment
As shown in Figure 1, by bevel arm piece layout design, manufacture arm mold, the hypomere of this mold is identical with supervisor's external diameter of skew T pipe fitting, epimere and skew T pipe fitting to prop up bore identical, between upper-lower section, be rounding off axially angled.
As shown in Figure 1, mold 2 is fixed on to the lower platform 3 of hydraulic press, the arm 4 of design well cutting length and angle is clipped in to hydraulic press upper mounting plate 1, medium-frequency heating coil is placed on to predetermined heating place of arm angle end, start medium frequency equipment pipe end is heated to predetermined temperature, remove medium-frequency heating coil, the upper cylinder half that starts hydraulic press presses down arm 4, turn up gradually in the lower end of arm 4 under the effect of pressure and mold, form the arm 4 that a flanging is identical with supervisor's profile, and supervisor's profile of flange becomes predetermined angle with arm.According to different molds, this angle can be 30 °, 45 °, 60 ° and other angle, and arm and supervisor can be same footpath and reducing.For can not be one-time formed, with acetylene rifle, flange position is heated, and limit heating edge presses down until moulding.The upper cylinder half that starts hydraulic press exits arm 4, approximately 50 millimeters of places outside the round and smooth excessive line of arm 4 flange, unnecessary part is cut away, arm 4 is buckled in to supervisor's 5 (Fig. 2, Fig. 3) predetermined position, along the profile cutting-up secant in arm 4 flange outsides, then by this line of cut in supervisor's 5 upper sheds, then by arm 4 together with being responsible for 5 butt welding, the steel welding skew T pipe fitting that arm of final formation and supervisor's intersecting lens are rounding off, as shown in Figure 2.
Claims (4)
1. the manufacturing technology of Novel steel welding skew T pipe fitting, first press the mould that skew T pipe fitting layout design is manufactured, supervisor's part of this mould is identical with supervisor's external diameter of skew T pipe fitting, prop up tube portion identical with a bore of skew T pipe fitting, and supervisor's part is rounding off with a tube portion, mould is fixed on to the lower platform of hydraulic press, then the steel pipe of holding angle successfully is clipped in to hydraulic press upper mounting plate place, angle end heating to steel pipe, reach after predetermined temperature, starting hydraulic press presses down steel pipe, make the angle end of steel pipe enter mould and turn up gradually under the restriction of mould, the arm flanging forming is identical with supervisor's profile, axial and the arm of flanging face is axially angled.After moulding, arm is taken out in mould, slice off unnecessary part outside arm flange, then arm is buckled in to the line of supervisor's predetermined position, press drawn line being responsible for upper shed, then arm and supervisor are welded together.
