The invention relates to the processing of metals by pressure and concerns the construction of rolling stock vehicles, and more specifically, the loading devices of screw rolling mills.

The purpose of the invention is to increase the reliability of work and reduce the time for reconfiguration when changing the assortment .10

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view; in fig. 3 - the same, at the time of loading the workpiece from the right lever; FIG. 4 is the same, top view; in fig. 5 - the same, in the initial position for loading the workpiece from the left lever; in fig. 6 - the same, top view; fla FIG. 7 - the same at the moment of loading from the left lever; in fig. 8 - the same, top view.

The device contains mounted on located on opposite sides of the axis of the rolling vertical shafts. 1 drive single-arm levers 2 with grooves, some walls 3 of which are hinged at the bottom and have rollers 4 with clamps of their position along the rolling axis in the form of a plate 5 with a lifting drive 6.

One-arm levers are mounted on vertical shafts on keys 7 with the possibility of vertical movement with subsequent fixing them in a certain position on the shaft with fastening elements 8.35

The rotational drive of the single-arm arms is made in the form of vertical shafts mounted in bearing supports 9 and mounted on the end surface of the stand of gears 10 and alternately interacting with them moving in rails 11 from the piston cylinder 12 of the rail 13. At the end of the rail there is a plate 14 interacting when moving a rail with contactless switches 15.

On one-arm levers mounted locking device 16 return 50 of the wall of the recess, made in the form of a spring-loaded right 17 17 stop 18.

The device works as follows.

In the initial position, one shoulder 2 arms rotated from the axis of rolling. The levers in height are set so that the axis of the loaded workpiece in IS30

The position of the lever is in the same horizontal plane with the axis of rolling.

Heated workpiece 19 is fed to the right single-arm lever. With the engagement of the piston cylinder 12 (the rod is pushed in) the rail 13 moves in the guides 11 in the direction of the arrow D, while the right gear 10 engages with the rail and, turning, rotates the right lever through the shaft 1. The right lever occupies the position (fig. 3 and 4) at the rolling axis (loading position). The rail 13 moves until the plate 14 closes the corresponding non-contact switch 15. The lift actuator 6 is turned on by a signal from the switch, and the plate 5 presses roller 4, the hinged wall 3 leans back and the workpiece rolls into the wiring mounted on the rolling axis, after which the rolling on the pass.

After receiving the command for the task of the next workpiece, the lifting drive 6 lowers the plate 5, the stop 18 with the help of the spring 17 returns the folding wall of the 3 recesses to the initial position. At the same time, the piston cylinder 12 (upward movement of the rod) and the rail 13, moving in the direction of the arrow C, returning the right lever to the initial position, engages with the left gear 10 (Fig. 5 and 6) and turns shaft 1 with the left pivot arm 2 to the loading position. On a signal from the switch 15, the lifting mechanism 6 activates a plate, which, pressing on the roller 4, causes the wall 3 to open. The preform is transferred to the rolling axis in the wiring.

Then the cycle repeats.

When switching to rolling another assortment of blanks, the swivel arms are reinstalled vertically on the shaft and the locking mechanism is fastened by the fastening element 8.

The proposed loading device of the helical rolling mill, as compared with the known ones, allows reducing the auxiliary time for loading the billet into the mill and increasing the reliability of operation, which contributes to the increase in the mill productivity.

3 133 The device also makes it possible to expand technological capabilities by providing the possibility of loading billets of various diameters into the mill. In this case, the time for reconfiguring the device is significantly reduced.

Claims (2)

1. A device for alternate transfer of rolled products, containing driving single-arm levers located on opposite sides of the line of the axial task of rolled products and having a hollow for rolling at the ends, so that, in order to increase the reliability of operation, 84 the levers are made in the form of gears mounted on vertically mounted shafts, carrying levers, and a common rail associated with the piston cylinder, with one wall of the recess of each single-arm lever pivotally attached to the bottom and provided with a roller at the end and its clamps. 2. The device according to claim 1, characterized in that, in order to reduce the time for restructuring when changing the assortment, each single-arm lever is mounted on a vertical shaft with the possibility of fixed axial movement.
