SU367920A1 - REMOVABLE STOP ON ROLLGAN1 ^ IL- - Google Patents

Description

The invention relates to the field of rolling production, more specifically to equipment. Known designs of retractable stops on the roller table are available, having only one single knot, providing cushioning of the breeze of the billet. In the proposed yiHOpe (but the drive lift of the shield at the same time performs the function of the shock absorber upon impact of the workpiece.

This is achieved by the fact that the slab in which the shield vertically moves is mounted in horizontal rails. A lever is pivotally attached to the plate, one arm of which is connected to the piston actuator stem, and iBTOipoe is connected to the shield. In this case, during one stroke of the rod 0: the shield moves relative to the plate and the plate moves with the shield IB of guides.

The proposed design of the stop eliminates the hang of the shield. The shield is raised, shock absorbed and lowered by a common drive. In this case, the supporting surface of the shield always remains perpendicular to the direction of movement of the groove.

In the drawing, a retractable stop for stopping the billet roller table is schematically drawn.

The shield 1 is installed vertically in the plate 2 and is movably connected to the lever 3. The lever 5 is pivotally connected to the plate and to the piston actuator stem 4. The plate is installed in horizontal mounting positions 5.

In the initial position, the piston drive rod 4 is retracted, the plate 2 is in the extreme right position, the shield / is lowered.

To stop the workpiece in the right cavity of the piston drive, pressure is created, the stem moves out and turns to raise the shield. Simultaneously, the plate is moved to the left. In the extreme upper position, the lever rests on the plate and the plate, together with the lever, reaches the leftmost position.

Upon impact of the workpiece on the shield, the plate is moved together with the shield, while the working medium in the right-hand cavity of the piston drive serves as a shock absorber. After stopping, the piston drive returns the entire system to the left and sets the workpiece on the roller table in a predetermined position.

In order to make way for the workpiece, pressure is created in the left cavity. together with the slab is retracted from the end of the workpiece and simultaneously lowered down. The stop is returned to its original position.
