Description
Technical field
The utility model relates to a kind of stainless steel tee pipe fitting processing tool, belongs to pipe fitting technical field of processing equipment.
Background technology
When tradition stainless steel pipeline needs threeway to connect, general employing opens angle on supervisor, and arm inserts the mode (as shown in Figure 1) of welding.This welding manner welder is difficult to hold, and need carry out docking the replacing with corner connection in the process of welding, and after having welded, welding contraction causes supervisor's distortion, and supervisor two ends can bend towards arm.Be difficult to shaping after pipe fitting distortion, because pipe fitting is all Hard link when car body is installed, the mouth of pipe circle or the mouth of pipe becomes large and diminishes all can cause and connects rear pipeline and leak.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of stainless steel tee pipe fitting processing tool, can reduce pipe fitting welding difficulty, improves pipeline welding quality.
According to the technical scheme that the utility model provides, a kind of stainless steel tee pipe fitting processing tool, comprise base plate, base plate arranges backing plate, feature is: Huff die installed by described backing plate, places pipe fitting in Huff die, and the sidewall of what husband's mould offers circular hole; Described pipe fitting sidewall offers elliptical aperture in advance, and this elliptical aperture is just to circular hole; Place steel ball at described tube intracavity, steel ball is connected with the lower end of pull bar, and the upper end of pull bar is stretched out by the circular hole on Huff die and is connected with draw-bar seat, draw-bar seat connecting fluid pressure device.
Further, described steel ball arranges screwed hole, steel ball is connected with the lower end of pull bar by screwed hole.
Further, the diameter of described steel ball is less than the internal diameter of pipe fitting, and is greater than the diameter of elliptical aperture on pipe fitting.
Further, described base plate installs locating piece, the upper end of locating piece is an inclined-plane.
Further, described Huff die is connected by hex bolts.
The utility model has the following advantages: (1) the utility model utilizes and opens elliptical aperture in advance, steel ball passes stretching tube wall makes threeway mouth of pipe rule rounding, is convenient to be welded in pipe-line system; (2) traditional more complicated tee pipe fitting manufacture craft simplified, only need precut elliptical aperture, the mouth of pipe saved in original traditional handicraft is cut sth. askew and is cut, and improves the mouth of pipe docking degree of accuracy and precision; (3) tee pipe fitting adopting tee pipe fitting processing tool described in the utility model to obtain, when being applied to the welding of train EMUs management system, change plane into by original mouth of pipe bevelled halving and dock, welding procedure difficulty reduces, not yielding after welding, improve pipeline welding quality.

Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 2 to 4: described stainless steel tee pipe fitting processing tool comprises base plate 1, backing plate 2, Huff die 3, pipe fitting 4, steel ball 5, hex bolts 6, pull bar 7, draw-bar seat 8, locating piece 10, circular hole 11, screwed hole 12, elliptical aperture 13 etc.
As shown in Figure 2 and Figure 3, the utility model comprises base plate 1, base plate 1 is arranged backing plate 2, backing plate 2 is installed Huff die 3, and Huff die 3 is connected by hex bolts 6, places pipe fitting 4 in Huff die 3, and the sidewall of what husband's mould 3 offers circular hole 11; Described pipe fitting 4 sidewall offers elliptical aperture 13 in advance, and this elliptical aperture 13 is just to circular hole 11; Steel ball 5 is placed at described pipe fitting 4 inner chamber, steel ball 5 is arranged screwed hole 12(as shown in Figure 4), steel ball 5 is connected with the lower end of pull bar 7 by screwed hole 12, and the upper end of pull bar 7 is stretched out by the circular hole 11 on Huff die 3 and is connected with draw-bar seat 8, draw-bar seat 8 connecting fluid pressure device; The diameter of described steel ball 5 is less than the internal diameter of pipe fitting 4, and is greater than the diameter of elliptical aperture on pipe fitting 4; In use, by hydraulic means lift draw-bar seat 8, drive draw-bar seat 8 and pull bar 7 upwards to promote, the steel ball of pull bar 7 lower end is then pulled out by the circular hole 11 on the hole that pipe fitting 4 is offered in advance and what husband's mould 3;
As shown in Figure 3, described base plate 1 installs locating piece 10, the upper end of locating piece 10 is an inclined-plane, and this inclined-plane is used for support tubes 4.
Operation principle of the present utility model: when adopting processing tool described in the utility model to make tee pipe fitting, first on pipe fitting 4, an elliptical aperture 13(is opened in advance as shown in Figure 5), the size of elliptical aperture needs by stainless steel stretched coefficient calculations, and just can determine optimum size by verification experimental verification, because the size and shape of elliptical aperture directly affects the tear(ing) strength of the rear bore edges that stretches.After elliptical aperture is held successfully, pipe fitting 4 is put into what husband's mould 3, again steel ball 5 is put into pipe fitting 4 inner chamber, aim at the position of opening elliptical aperture in advance, pull bar 7 is screwed in the screwed hole 12 at steel ball 5 top, by hydraulic means lift draw-bar seat 8 and pull bar 7, steel ball 5 also lifts thereupon, during to elliptical aperture position, by lift and the stainless stretching action of steel ball 5, formation rule mouth of pipe end face 14(is as shown in Figure 6), a kind of special tee pipe fitting being convenient to pipeline welding machines.
