Said structure roll pier pipe machine, the end of being rolled the pier pipe is heated, is rolled the pier pipe by the feed arrangement clamping and is fed to and rolls the pier pipe unit, rolls the pier device and is rolled pier by drive unit and transmission device to rolling the pier pipe.

Description of drawings

Fig. 1 is the cross-sectional schematic of the utility model embodiment.

Fig. 2 is a schematic top plan view embodiment illustrated in fig. 1.

Specific embodiment

Below in conjunction with drawings and Examples the pier pipe machine that rolls of the present utility model is described in further detail.

As depicted in figs. 1 and 2, the pier pipe machine that rolls of the present utility model is provided with frame 1, be used to and roll pier pipe machine a carrying platform is provided, frame 1 is provided with three riser supports 21,22,23, riser support 21 is provided with inlet pipe through hole 19, inlet pipe mouth 19 both sides, riser support 21 upper edge are respectively arranged with two hydraulic jacks 2, be used for being provided power along the horizontal axis feeding to rolling the pier pipe, hydraulic jack 2 is derived end and is stretched to riser support 22, and hydraulic jack 2 derives that end is provided with that the quilts that are used to tighten in the inlet pipe through hole 19 roll the pier pipe and in axially movable clamp mechanism 3.

Riser support 22, be provided with between 23 and roll pier device 4, roll the driven gear 5 that pier device 4 two ends are respectively arranged with and are rolled pier pipe concentric, be arranged with at least three cylindrical rollers 6 (can also for coniform) between two driven gears 5 in parallel, described driven gear 5 is separately positioned on

riser support

22 and 23, wherein, driven gear 5 centers that are arranged on the riser support 22 are provided with inlet pipe mouth 20, described roll 6 ends along driven gear 5 concentric circles uniform be arranged in the driven gear 5 and roll 6 inscribed circle diameters with to be rolled the pier external diameter of pipe suitable, described roll two ends are respectively arranged with bearing, and bearing is separately positioned in the driven gear at two ends; The driven gear 5 inboard centers that are arranged on the riser support 23 are provided with taper pier nose 8, and pier nose 8 bigger diameter ends are provided with bearing, and bearing is arranged in the driven gear 5, and pier nose 8 is used for being rolled pier pipe end location and is controlled to product pipe end internal diameter.

1 side of frame is provided with motor 10 and reductor 11, reductor 11 outputs are provided with transmission device, transmission device is provided with shaft coupling 12 and power transmission shaft 14, shaft coupling 12 1 ends are connected with reductor 11 output shafts, the other end is connected with power transmission shaft 14, the power transmission shaft two ends are separately positioned on

riser support

22 and 23, are respectively arranged with on the power transmission shaft 14 and driven gear 5 meshed gears 15.
