Description

one

The invention relates to etching machines for straightening especially toicostinic and profiled tubes and can be used in machine building and metallurgical industries.

The known straightening device T (whether the remaining pipes contain straightened rolls 1 on the frame along the axis of straightening.

The rolls are adjusted to the determined size of the cross-section of the pipe, and the size of the cross-section of the cross-section of the pipe is intermepiro (ipprpemer, triangular or square cut). Since the tube during straightening is wrapped around its axis, the force of the rolls acting on the tube is also alternated with the fact that it doesn’t lead to a disruption in the straightening process and the required length of the pipe is not reached.

In addition, local sm of pipe stems occur in connection with large bolts at the point of roll contact and pipe and tearing it over the surface of the roller as a result of rolls slipping.

The goal of ii3 (j6peTenHH is to provide upaLiKii capabilities for thin-walled profile tubes.

This goal is achieved by the fact that the device is siapticotically arranged between the rollers of the guide rollers, the axes of which intersect the rolls with the iodine axis of the right angle, while the working surfaces of the rolls and the paired rollers are made of elastic material.

The thickness of the coating depends on the hardness of the coating (resip) and the elastic deformation required to compensate for the difference in the cross-sectional dimensions of the pipe.

Ma FIG. 1 shows the proposed device; FIG. 2 - the same, top view.

The device contains a working stand 1 with directed rollers 2, the smallpox of which is spaced with axes of inclined horizontal rolls 3 iodine angles m. Rolls and rollers are coated with an elastic material.

The rollers are driven in rotation by the drives 4. The rollers are mounted between the rollers.

The device works as follows.

The irivods 4 are turned on, imparting a rolling movement to the rolls 3. The pipe to be edited is fed into working cage 1. The rolls capture it and move it along the axis of the shaft, at the same time communicating with it the movement of movement. Figure 2, rolls 2 hold the pipe on the axis of the axis.

After being bent under the action of the rolls, the pipe acquires the necessary mold. This is facilitated by the rubber coating of the rolls, which makes the difference) to the dimensions of the iKjiijpcM multi-section prof. Pipe,.-Iinioiujr
