Abstract

The utility model relates to a steel pipe straightening machine, which comprises a basal seat, a motor, a speed reducer, and a straightening mechanism. The steel pipe straightening machine is characterized in that the straightening mechanism is composed of a roller group which is arranged parallel to a workpiece which is straightened and realizes enclosed and rotary extrusion and straightening to the workpiece, a rotary disk for installing the roller group, a hollow shaft which is fixedly connected with the rotary disk and drives the rotary disk to rotate under the action of a transmission mechanism, and a supporting seat which is arranged on the basal seat and installs the hollow shaft. The steel pipe straightening machine has the positive effect that the straight line degree of the workpiece which is straightened can be effectively ensured; due to the fact that a roller not only has revolution of following the rotary disk to move, but also has autorotation, therefore, the friction between the roller and the workpiece which is straightened is reduced, and thereby, the service life of the workpiece which is straightened is ensured.

Description

Steel tube straightening machine

Relate to steel pipe alignment equipment by the utility model.

Existing steel tube straightening machine has two kinds substantially, and the one, hyperbola cross roll alignment mode; The 2nd, and by the vertical alignment mode that roll stacks is set of gyp's part.Their major defect is: can only realize that thick school promptly big curved diminishing, particularly also the phenomenon that workpiece is twisted distortion can take place in to the workpiece alignment process.

The purpose of this utility model provides and a kind ofly can make the steel tube straightening machine that is recovered former linearity by gyp's part.

The purpose of this utility model is achieved in that a kind of steel tube straightening machine, it comprises pedestal, motor, decelerator and aligning mechanism, it is characterized in that said aligning mechanism be by be arranged in parallel by gyp's part it realize is surrounded the roll stacks of rotation extruding alignment, the rotating disk of roll stacks is installed, the effect that is connected in transmission mechanism with rotating disk drives down the hollow shaft of dial rotation, places the supporting base that hollow shaft is installed on the pedestal to constitute.

Be continuous convex concave surface on its every roll of said roll stacks.

On the rotating disk of said installation roll stacks, be provided with the guiding adjustment notch that can make roll shop building, be provided with in the outside of hollow shaft top rotary table and can impel roll shop building apart from the clutch that changes apart from changing.

Its roll number of said roll stacks can be provided with 3～5, adopts 3 to get final product usually.

Be provided with the first revisal roll at the arrival end that is entered said aligning mechanism by gyp's part, active transportation roll and thick school roll also are provided with output wheel at the port of export of said aligning mechanism.

Every roll of said roll stacks is equipped with bolster, and is connected with rotating disk by it.

Good effect of the present utility model:

Since alignment roll stacks of the present utility model be arranged in parallel by gyp's part, so can guarantee to be gone out the linearity of workpiece effectively by the school.

2. because the roll shop building distance in the roll stacks is adjustable, thus can be according to the distance of being adjusted roll shop building by the size of gyp's part diameter, with its reach can be entered aligning mechanism by gyp's part again can be by the purpose of alignment.

3. because the existing revolution moving with rotating disk of roll has rotation again, thus reduced and by the friction between gyp's part, thus guaranteed by the service life of gyp's part.

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the A-A generalized section of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in further details.

In Fig. 1, road wheel 1,32 is housed under the pedestal 4, support roller 7 places on the carriage 8.First revisal roll 9,10 is arranged on the first revisal tank tower 11, and the first revisal roll can be 4 also can be 2, and present embodiment adopts 2, is provided with first revisal and adjusts bolt 12 on the first revisal tank tower.Active transportation roll 6,14 is arranged on to be carried on the tank tower 13, is provided with to carry on the conveying tank tower and adjusts bolt 15.Thick school roll 2,3,16 is arranged on the thick school tank tower 18, is provided with thick school and adjusts bolt 17 on the tank tower of thick school.

Alignment roll stacks 22 in the present embodiment is to adopt three, and they are arranged on the rotating disk 29 by bolster respectively, and bolster and alignment roll shop building are provided with bearing arrangement.For the distance that makes the alignment roll shop building can adapt to the needs of different-diameter steel pipe alignment, on rotating disk 29, be provided with the guiding of placing bolster 44 and adjust groove 43 (as shown in Figure 2).Centre bore on the rotating disk 29 and hollow shaft 21 are connected, and hollow shaft stands sprocket wheel 24 drivings that decelerator drives.Be provided with the clutch actuating mechanism 23 that can change alignment roll shop building distance on the hollow shaft of the rotating disk outside, clutch actuating mechanism is done the spacing adjustment at the bolster that makes the alignment roll under the effect of clutch operating lever 19 and connecting rod 20 in guiding is adjusted notch.

Output wheel 27,31 is arranged on the output tank tower 25, also is provided with output and adjusts bolt 26 on the output tank tower.Main reducing gear 34 is driven by main motor 35.Driven by decelerator 40 by movable sprocket 3, decelerator 40 is driven by motor 36.
