Abstract

The invention can be used in the metallurgical industry for turning long products. The purpose of the invention is to enable the profile to be turned, preferably a diamond, from any position. The tilter has a frame 1 with supporting rollers 2, two parallel cradles, tilting rollers 5 of each cradle are mounted rigidly at a distance from each other, smaller diagonal and larger smaller diagonal of the turning diamond, and eyelets 6 of each cradle are located on opposite sides of the rolling axis the angle between them is 60-70 °. The eye of each cradle is connected to the pneumatic cylinder 10 through the rocker 8, providing simultaneous rotation of the cradles in different directions. According to the tilter, it is possible to tilt onto the edge freely moving on any face along the roller table long products with a cross section of a rhombus, to hold it in this position and set it without stopping into the rolling mill stand. 3 il. with $ (L / ff I About sl sj o Fiz.g

Description

one

The invention relates to the processing of metals by pressure and can be used to carry out turning and the task of long products with a diamond cross section into gauges of rolling stands.

The purpose of the invention is to enable the profile to be turned, preferably a diamond, from any position.

FIG. 1 shows the tilter of long products} in FIG. 2 shows section A-A in FIG. 1 in FIG. 3 - the position of the gantry cradles at the time of rolling.

The tilter of long products with a cross-section of a rhombus consists of frame 1, in which support rollers 2 are placed along an arc of a circle. The tilting cradles 3 and 4, installed in the frame aperture, rest on support rollers. Each cradle and two curved rollers. 5 rollers with fixed base

M, and in the lower part of the cradle there is an eyelet 6, which is located at an angle, 30-35 to the vertical axis, perpendicular to the rolling axis. The cradle 3 is installed so that the eye is located on the left side of the rolling axis, and the cradle 4 is installed so that the eye is located on the right side of the rolling axis.

Both lugs rest on the copier 7, and the beam 8, with the axis of rotation in the middle, is pivotally connected to each of the lugs by two equal turning points 9. The rod of the pneumatic cylinder 10 is pivotally connected to the beam.

Tilter works as follows.

Long products with a diamond cross section, passage through the wire part of the beaming cradles 3 and 4, may be in the right-hand and left-hand positions. Consider the work of the turntable with the right-sided arrangement of the tilted rhombus (Fig. 3).

After passing the car through the wire part of the kanta cux lyupec from the photo sensor (not shown), signal / 1 is sent to turn on the pneumatic cylinder 10, which rotates the beam 8 and transmits the translational versatile movement of tam 9, which pull the lugs 6 simultaneously.

melting cradles 3 and 4 in order to facilitate the process of turning. When turning, the tilting cradle 3 grabs the rolling for a large diagonal (Fig. 4), and the cradle 4 at this moment bypasses rolling on the small diagonal of the tilted rhombus. At the last moment, the rollers of both of the folding cradles grab the rolling for a large diagonal and hold it in that position, and with their own weight press the rolling onto the roller table, not obstructing the task of the roller table in the rolling stand.

If the rolled products come to the wire part of the turning edge cradle with a diamond-sided left-side arrangement, the rolling profile of the rolling profile is produced by the turning edge of the cradle 4, and the cradle 2 bypasses the rental along the small diagonal until the cradle is caught by both cradles.

When the rolling will be captured by rolling rollers, a signal is sent to the pneumatic cylinder 10 to return the cradles to their original position, and after the rolled steel leaves the wired portion of the curved cradles, the tilter will be in the initial working position.

Thus, the proposed tilter of long-rolled products provides for easing the working conditions of the roller stacker, the possibility of automating the process of turning the metal, as well as increasing the productivity of the mill.

F o rm ula invention

A tilter of long products, including a frame with support rollers, a turning edge of a cradle with a turning rollers and a drive for its rotation associated with the cradle through a propshna, characterized in that, in order to allow the profile to be turned, mainly a diamond, from any position, the tilter the second kantaya cradle with an eye installed parallel to the first, with this eye of the cradles are located on opposite sides of the axis of the rolled steel with an angle between them 60-70, the eye of each of the cradles is connected to the drive through the yoke, and The rollers are installed in the cradle with the possibility of rigid fixation relative to it.
