Abstract
The invention discloses a saddle forming process for an interface between main pipe and branch pipe with an inclination angle and a welding method thereof. The saddle forming process comprises the following steps: a metal block consistent with outside dimension of the main pipe and the branch pipe is punched, an elliptical hole is punched on the metal block according to the inner diameter of the branch pipe, the elliptical hole is stretched to be a boss according to the inclination angle between the main pipe and the branch pipe, the metal block is punched according to the outer diameter of the main pipe to form a curved surface consistent with peripheral curvature of the main pipe, the surplus part of the metal block periphery is cut off according to the size of a welded surface, etc. The welding method comprises the following steps: a hole is drilled at the place where the main pipe needs a branch; one end of the branch pipe is welded with the boss of the saddle; and the curved surface on the saddle consistent with the peripheral curvature of the main pipe is jointed and welded with the borehole position on the main pipe, etc. The saddle forming process for the interface between the main pipe and the branch pipe with the inclination angle and the welding method thereof guarantee the welding flatness and the welding intensity, and avoid the obstruction resulting from inserting the branch pipe into the main pipe.
Description
Technical field
The present invention relates to a kind of on being responsible for the method for branch pipe welded directly to the run pipe, more particularly, the present invention relates to a kind of metal that is used for any angle of inclination be responsible for arm between interface the saddle moulding process and adopt the saddle moulding process to be connected that metal is responsible for and the welding method of arm.
Background technology
Because the special construction of automobile engine, use in the metal cooling-pipe road at automobile, need be with circulation fluid to the processing of lowering the temperature of described engine, meanwhile, also need to be beneficial to the heat energy of engine generation to being incubated such as oil supply system, driver's cabin and some privileged sites and heating, so, need in the main line of metal cooling, tell a lot of bye-passes.Yet the arm that is used for these bye-passes has and much is and is responsible for both not parallel also off plumb, they with the person in charge between formed different space angles.
In order to satisfy above requirement, existing branching method is: boring on being responsible for, and then arm is inserted drill hole and weld.This method is fairly simple, but has following shortcoming:
(1) bonding area only is the person in charge's wall thickness, is difficult to guarantee the flatness of solder side, causes weld strength poor;
(2) welding manner of insertion arm on being responsible for very easily blocks and is responsible for pipeline, thereby causes accident potential.
Summary of the invention
Problem to be solved by this invention overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of person in charge's arm interface saddle moulding process and welding method that is used for the angle of inclination is provided for this reason.
The present invention is used for person in charge's arm interface saddle moulding process at angle of inclination, may further comprise the steps:
(1) goes out the metal tablet that the outside dimension of size, shape and the person in charge and arm adapts with punch press;
(2) according to the internal diameter size of arm, go out elliptical aperture in described metal tablet upper punch with punch press;
(3) according to be responsible for and arm between the angle of inclination, the elliptical aperture that stretches on the described metal tablet with hydraulic press and particular manufacturing craft makes it to become boss;
(4) according to the external diameter of being responsible for, carry out punching press, make the edge of described metal tablet present the curved surface that the periphery curvature with the described person in charge matches with hydraulic press and particular manufacturing craft;
(5) according to the size of solder side, the redundance excision with described metal tablet periphery makes it moulding.
The present invention adopts the saddle realization of above-mentioned moulding to have the method for person in charge's arm interface welding at angle of inclination, may further comprise the steps:
(1) need bifurcation boring the person in charge, this boring should adapt with the arm diameter that will be connected;
(2) end of arm and the boss on the described saddle are welded together;
(3) curved surface and the bore position on the described person in charge that match with person in charge's periphery curvature on the described saddle are fitted and be welded as a whole.
The present invention is used for person in charge's arm interface saddle moulding process at angle of inclination and saddle that welding method relates to is made of the metal tablet, described metal tablet is provided with the curved surface that the periphery curvature with the described person in charge matches, described metal tablet is provided with the boss that is fit to angle of inclination between the described person in charge and the arm, and the internal diameter of described boss equals the external diameter of described arm.
The present invention compared with prior art, its beneficial effect is: enlarged the bonding area that the person in charge is connected with arm, guaranteed the flatness and the weld strength of solder side; Avoid prior art that arm is inserted and be responsible for person in charge's choking phenomenon that pipeline caused.
Description of drawings
Fig. 1 is the shaping schematic view of saddle among the present invention;
Fig. 2 is the schematic diagram that among the present invention the boss of arm and saddle spare is welded together;
Fig. 3 adopts saddle spare to realize having the person in charge at angle of inclination and the schematic diagram of arm welding among the present invention.
The specific embodiment
Describe the present invention below in conjunction with drawings and Examples:
Fig. 1 shows the forming process of saddle among the present invention.With reference to the forming process that Fig. 1 (a), Fig. 1 (b), Fig. 1 (c), Fig. 1 (d) illustrate, the forming method of saddle comprises the following steps: among the present invention
(1) person in charge who connects as required and the outside dimension of arm are gone out size and shape and its metal tablet 1 that is fit to punch press;
(2) according to the internal diameter size of arm, on described metal tablet 1, go out elliptical aperture 2 with punch press;
(3) according to be responsible for and arm between the angle of inclination, with stretch elliptical aperture 2 on the described metal tablet 1 of hydraulic press and particular manufacturing craft, make it to become gradient is suitable for being responsible for and arm between the boss 3 at angle of inclination;
(4) according to the external diameter of being responsible for, carry out punching press, make described metal tablet 1 convex platform 3 part in addition become the curved surface that the periphery curvature with the described person in charge matches with hydraulic press and particular manufacturing craft;
(5) last, according to the size needs of solder side, the redundance excision with described metal tablet 1 periphery makes it moulding.
Fig. 1 (d) is the structure situation of moulding saddle.As seen from the figure, described saddle comprises metal charge sheet 1, the shape and size of described metal tablet 1 should be suitable for the person in charge of needs connection and the outside dimension of arm, described metal tablet 1 is set to the curved surface 4 that the periphery curvature with the described person in charge matches, 1 is provided with the boss 3 that forms by drawing mode on described metal tablet, the angle of inclination of described boss 3 should and the described person in charge and arm between the angle of inclination fit, the internal diameter of described boss 3 equal will connected arm external diameter.
Fig. 2, Fig. 3 show the situation that the present invention welds together the boss 3 of arm 5 and saddle respectively and adopt saddle to realize the situation of joint weld between the person in charge 6 with angle of inclination and arm 5.
