the specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
As shown in Figure 1, 2, 3, vertical pipe expander, comprises base 1, and portal frame 10 is installed on it, and the line slideway 16 being parallel to each other is installed on 10 2 leading flanks of frame separately, and the interior side rails 101 being parallel to each other is installed on 10 2 medial surfaces of frame separately.
Above-mentioned rollers assembly 81 comprises that a pair of parallel pulley keeping at a certain distance away is to 811, by this to parallel pulley to 811 on interior side rails 101, force transmission rack 8 is mobile more steady on interior side rails 101 like this, frictional force is less, sees Fig. 4.
For guiding better force transmission rack 8, also between the parallel pulley of roll wheel assembly 81 is to 811, vertical sliding wheel 812 is set.
The screw mandrel sprocket wheel 91 of endoporus with feather key 92 is respectively equipped with at power seat 9 two ends, two parallel upper screw rods 6 are set on respectively in two screw mandrel sprocket wheel 91 holes, feather key 92 is embedded in the guiding groove 61 of upper screw rod 6, the drive unit 601 of upper screw rod 6 is arranged on power seat 9, drive unit 601 comprises two drive sprockets 94, be connected by chain 93 with two screw mandrel sprocket wheels 91 that are set on upper screw rod 6 respectively, upper screw rod 6 lower ends connect and support enlarging seat 5 with bulb, the upper screw rod nut 602 being set on upper screw rod 6 is limited to by the guiding groove 603 of one side on the line slideway 16 of frame, see Fig. 5.
For making lower feed screw nut's 17 stress equalizations and better mobile, at lower feed screw nut's 17 the opposite side that relatively moves back mould cylinder 18 piston rods, guide rod 41 is set, guide rod 41 passes lower feed screw nut's 17 sidepiece and is fixed on and moves back on die holder 4, sees Fig. 3.
Above-mentioned move back die holder 4 tops also install to support in enlarging seat 5(figure show and draw).
As Fig. 1,2,3, a cat ladder 20 is also set after frame, described cat ladder 20 belows are fixed on base 1, and top is fixed in frame 10, on the one hand operating maintenance is become easily, has also strengthened the counter-bending ability of equipment simultaneously.
When vertical pipe expander work of the present invention, first drive upper screw rod 6 to rotate by the drive unit 601 of upper screw rod 6, thereby change its upper screw rod nut 602 and the position with the fixing support enlarging seat 5 of upper screw rod nut 602, the determining positions of upper screw rod nut 602 original position of carrying out pipe fitting and expanding cup-shaped recess and pipe end taper flange; By the drive unit 201 of lower screw mandrel 2, drive lower screw mandrel 2 to rotate, thereby change the position of its upper screw rod nut 602, and then the position of moving back die holder 4 fixed with upper screw rod nut 602 of change and the position of moving back the relative workpiece 15 of die holder 4; By the position of ball screw 3 motivation of adjustment seats 9, i.e. the initial position of expander roll 14 relative workpiece 15.
After adjusting, on stacked rotary table, install workpiece, clamp pipe fitting U-shaped end and the other end, move back 18 drives of mould cylinder and move back die holder 4 to next segment distance compression heat exchanger fin, just can start working.
