The specific embodiment

For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.

With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, a kind of outlet elbow device, comprise the reeded disk 2 of tool, in the vertical direction of pipe fitting 10 to be processed, be provided with advanced and retreat pressure pipe structure 3 and the pipe bending mechanism 4 of pushing down the last end of processed pipe fitting, described pipe bending mechanism pedestal 41 relatively frame 1 is rotated, and is provided with the advanced and retreat indent 42 that can be connected with adjacent advance and retreat pressure pipe structure on described pedestal.

In the present embodiment, the linking line of described pressure pipe structure and adjacent pipe bending mechanism is crossed disc centre line 21, described pressure pipe structure comprises the reeded briquetting 31 of tool, described briquetting bottom is connected with a slide plate 32, described slide plate below is tilting the cylinder 33 of promotion, push rod 331 upper ends and the slide plate bottom side of described promotion cylinder are hinged, and promotion cylinder block 332 is hinged to promote briquetting with frame and moves ahead to disk.

In order to make briquetting motion, described briquetting front side is connected with and promotes the moving cylinder 34 that briquetting seesaws.

In the present embodiment, for the indent of can advancing and retreat is installed, the described indent bottom of advancing and retreat is connected with seat board 45 upper surfaces, described seat board bottom is connected with the isometric rocking bar 43 of pair of parallel, described a pair of isometric rocking bar and seat board and pedestal form parallelogram linkage, described pedestal bottom is tilting rotary cylinder 44, and rotary cylinder push rod 441 upper ends and rocking bar middle part are hinged, and described rotary cylinder cylinder body 442 is hinged with pedestal.

For the ease of pedestal rotation, described pedestal bottom is connected with a driven gear 5, and described frame is provided with a driving gear matching with driven gear 6, and described driving gear drives 7 by motor, and motor is stepper motor.
