Description

one

The invention relates to rolling production, in particular to the equipment of rolling stands.

Known introductory roller wiring, comprising a housing, is rigidly mounted: with a cassette mounted on a reinforcing bar.

Such a xfus installation makes it difficult to roll into rolls at an angle to the horizon, which is the case, for example, when the rolls are reground.

The described wiring differs from the known one in that its body is freely supported on the inclined bottom of the cassette. This facilitates the task of rolling into rolls at an angle to the horizon.

In addition, the body of the proposed wiring is provided with vertical strips covering a1; xi cassettes, and the bar interacting with the cassette from the rolls has a bearing surface in the form of an arc of a circle centered on the axis of rolling, which prevents mutual horizontal movement of the body and the cassette.

FIG. 1 shows the described wiring in the initial position, side view; in fig. 2 - the same, with the steady rolling process, the cut; in fig. 3 is a section along A-A in FIG. 2

The input wiring includes freely supported on the inclined bottom of the cassette 1, the housing 2.

2

The guide rollers 3 and passes 4 are mounted inside the case. The case is equipped with adjusting screws 5. The vertical bars 6 and the protrusions 7 mounted on the case prevent horizontal movement of the case relative to the cassette. To prevent ;: impacting the case against the cassette during the passage ;. metal plate b has a reference surface in the form of d, ugi circle with zeitr pas axis rolling.

In the initial position, the body rests on the bottom of the cassette and the longitudinal axis of the body is with a horizontal plane and a certain angle of inclination, replaced by screws 5. The entrance to the rolled steel is set into rolls at an angle to the horizontal plane. After the front end of the rolling rollers has been gripped, the casing, rotating in the vertical plane inside the cassette, is raised by the metal passing through it to align its axis with the rolling axis.

After the metal is rolled, the body returns to its original position under the action of its own weight.

Claims (2)

1. Introduction roller rolling wiring mill housing a cassette mounted on a reinforcing bar, characterized in that, in order to facilitate the task of rolling rolls under the angle. To the horizontal plane, the body is freely supported on the bottom of the cassette. 2. Wiring according to claim 1, characterized in that, in order to prevent the wiring housing from moving horizontally relative to the cassette, the housing is provided with vertical strips covering the cassette's cheeks, the roll-side planar having a bearing surface in the form of an arc of a circle centered on the rolling axis .
