Description

A twisting guide for improving work rate

technical field

The utility model relates to the technical field of rough rolling guide and guard, in particular to a torsion guide guard which improves the operation rate.

Background technique

The rough rolling area of the bar workshop is all flat rolling stands, and the elliptical material-shaped rolled pieces enter the next rolling mill. It is necessary to adjust the incoming steel angle through the twist guide. The original design twist guide completely relies on the upper and lower twist guide wheels to move the rolling If the torsion angle is too large, the torsion angle of the torsion guide wheel will be unstable, the bearing will be damaged frequently, and the production error will be affected, which will affect the operation rate and output.

SUMMARY OF THE INVENTION

The purpose of the utility model is to solve the problem that the bearing of the torsion guide wheel is easily damaged when the torsion angle is too large, and to provide a torsion guide that improves the work rate.

The specific scheme of the utility model is as follows: a torsion guide for improving the work rate, comprising a guide frame, an upper guide wheel and a lower guide wheel are installed in the guide frame, and a center shaft is respectively provided in the center of the upper guide wheel and the lower guide wheel, Both ends of the central shaft are connected to the guide frame through bearings. The outer walls of the upper guide wheel and the lower guide wheel are each provided with a conical section, and an inclined rolling channel is formed between the two conical sections. The center line of the rolling channel and the horizontal plane There is an included angle between them. The guide frame is equipped with a pre-twist mechanism at the entrance of the rolling channel. The center of the pre-twist mechanism is provided with a pre-twist channel. The outer end of the pre-twist channel is provided with a feeding port, and the inner end is provided with an outlet The center line of the feed port is parallel to the horizontal plane, the center line of the discharge port and the horizontal plane are at an angle b, and b is less than a, and the pre-twist channel transitions smoothly from the feed port to the discharge port.

In the present invention, 3°<a-b<10°.

The length of the pre-twist channel of the present invention in the horizontal direction is 200-500 mm.

The utility model has the following beneficial effects: by setting the pre-twisting mechanism, the torsion angle of the torsion guide wheel is reduced, thereby reducing the bearing force, improving the service life of the torsion guide wheel, reducing the replacement frequency of the torsion guide and the number of steel stacking, saving energy Production time, increase operability and yield.

Detailed ways

Referring to Figures 1-5, this embodiment is a torsion guide for improving work efficiency, including a guide frame 1, and the guide frame 1 is equipped with an upper guide wheel 2 and a lower guide wheel 5, and the upper guide wheel 2 and the lower guide wheel. 5. There is a central shaft in the center. Both ends of the central shaft are connected to the guide frame 1 through bearings. The outer walls of the upper guide wheel 2 and the lower guide wheel 5 are each provided with a tapered section, and an inclined rolling piece is formed between the two tapered sections. The channel, the center line of the rolling channel and the horizontal plane are at an angle a. The guide frame 1 is equipped with a pre-twisting mechanism 3 at the entrance of the rolling channel. The center of the pre-twisting mechanism 3 is provided with a pre-twisting channel 4. The outer end of the channel 4 is provided with a feeding port, and the inner end is provided with a discharging port. As shown in Figure 4, the center line of the feeding port is parallel to the horizontal plane, and the center line of the discharging port is at an angle b with the horizontal plane, and b is less than a, the pre-twist channel 4 smoothly transitions from the feed port to the discharge port.

In this embodiment, a-b=5°, generally between 3° and 10°.

The length of the pre-twist channel 4 in the present embodiment in the horizontal direction is 300 mm (generally set in the range of 200-500 mm).

In this embodiment, on the basis of the prior art twisting guide, a pre-twisting mechanism 3 is set up, and the guide and guard enter the inner cavity of the steel guide groove from the horizontal direction to the angle b through the pre-twisting channel 4, so that the rolled piece is before the twisting guide wheel. By pre-twisting a certain angle of the guide groove, the torsion angle of the guide wheel is reduced from a to a-b.
