Abstract

The invention relates to the field of pipe production and is intended for applying a centering recess at the end of the heated billet prior to piercing. The goal is to increase productivity and reliability. The device consists of a frame 1, on which a center-driver is placed for applying a recess on the workpiece and a centering piece on the center-axle axis, consisting of two prisms 3 and 4 placed in the slots of the bed and having individual drives 5 and 6 of horizontal movement and motion stops. In the frame above the center-axle axis there is an upper opening for loading the blanks, and below the axis and shifting towards the prism 3 there is a lower opening b for unloading the blanks. The folding single-arm lever 11 is lowered by the shoulder into the upper opening a and has the ability to swing up when it comes in contact with the prism 3. The swing axis 12 of the lever 11 is located above the prism 3. The device ensures a clear flow of blanks to the centering axis and removal, which contributes to reliable and productive work . 7 il.

Description

one

The invention relates to pipe production and is intended for applying a centering recess at the end of a heated billet before piercing.

The purpose of the invention is to improve the performance and reliability of

FIG. “1 depicts a section from on a heating furnace to a piercing station with an installed centrifuge; in FIG. 2 a section in FIG. 1 | in FIG. 3, node I in FIG. 28, the initial position; Fig 4 is the same; batching of blanks with a prism and a lever; in FIG. 3, the movement of the workpiece prisms on the discharge axis; Figs "6 - fe03 ° of the gate of the prism to its original position, lowering the lever to its original position; in fig section bb in fig.Z ,,

The device for centering the heated billet consists of a bed 1, on which centering 2 is placed, and a centering billet consisting of two prisms 3 and 4 with their movement drives 5 and 6 and limiters 7 and; 8. The device for centering the heated blanks is equipped with a loading 9 and a dispensing 10 sloping grids with a folding single-arm lever 11, fitted on the frame on the swing axis 12a on the frame on the swing axis 12a.

b bridges for skipping goods from ° boot to the dispensing lattice. The loading grid is placed above the prism 4, the folding one shoulder lever 1 is lowered by the shoulder into the upper opening a stash-1y and has the ability to turn upwards in tact with the prism. The Kachan axis 12 fishes P is placed above the prism 3,

A device for centering the heating of the Ttix billets is located between the heating furnace 13 and the chute 14 of the hydrographic mill 15 The heating furnace has a loading 16 and a unloading 17 roller tables, the discharge roller table is equipped with a stop 18 and an ejector 19 with a 20 "drive

The device works after the color.

The heated billet 2 from the heating furnace 13 is transported along the roller table 17 to the stop 18 ". Then the drive 20 of the ejector 119 is turned on and the billet is fed to the loading inclined grate: 9p. Then the filling goes to the upper opening a (Fig. 3). Lever 11 does not allow far.

Next to the blank, roll down into the lower opening b. After the workpiece has entered the upper opening a, the drive 5 of the prism 3 is turned on, as a result it moves, raising the lever 11, which cuts off the rest of the workpiece (Fig 4). In this case, the stroke of the prism 3 is limited by the stops 7 in such a way that the workpiece is brought onto the axis of the centering machine: 2, After the prism 3 has pressed the workpiece to the prism 4, the centering device 2n turns on the end of the workpiece. After

When the recess is applied, both the actuators 5 and 6 move the prisms, as a result, the workpiece is mixed, from the centering axis (Fig. 5) into the lower unloading opening and rolled down

0 All-inclined grate 10 into the chute 14.

After that, the prism 4 returns to its original position, the lever is lowered under its own weight, and the next

The blanks enter the opening a. The cycle then repeats.

The proposed zatsentrov); infrared heated billets compared with the known, allows you to more than perpendicular; e ;; - the strength and reliability of its work. In addition, the presence of regulating elements, limiting the course of the prism. the design of the centr, will allow centering the workpiece without a strong clamping, which will improve the surface quality of the pipes, as well as increase the yield.

Invention Form

A device for centering heated billets, including a frame, placed on it by the center-driver and the centering of the billet on the axis of the centering machine in the form of two prisms with drives for their movement, so that, in order to increase productivity and reliability, it is equipped with a loading and a lateral inclined slats and a sliding single-arm lever mounted on a frame, which is made with the upper, higher from the center of the center, and W-1ZHNIM openings for the passage of workpieces from the loading and to the issuing inclined grating, etc This rtag omitted shshchom Bytes upper opening of the frame and is pivotable upward when kontak; -t one of the prisms
