SU373054A1 - DEVICE FOR CORRECTION OF END PANELS OF MOUNTING JOINTS OF ROLLED COVERS - Google Patents

Description

The invention relates to devices for assembling and welding rolls of shells, in particular, to devices for correcting the end sections of the MO, butt of the shells before closing for welding of the joined edges.

A device is known for fixing the end sections of the rolled panels, comprising guide posts on which a movable carriage is mounted with accommodated tools, and a cable-and-block system with a drive.

However, this device does not allow for evenly correcting the ends of the joined shells as a result of the application of local areas, and the weld is wavy with local stress concentrations.

In order to improve the quality of the resulting edge, in the proposed device, the carriage is made of polypropylene in the form of a horseshoe-shaped frame, on the parallel walls of which tools are located in the form of driven adjustable leveling rolls, the gap between which corresponds to the thickness of the shell being processed, and the drive of the rolls is synchronized with the drive of the cable-block system.

FIG. 1 shows the proposed device; in fig. 2 is a view along arrow A in FIG. 1. The device consists of two guides.

Installed on the base plate 2 with removable shoes 3. On the guides / connected to each other by a cross bar 4, is mounted with the possibility of reciprocating movement of the carriage 5, which is balanced by the counterweight 6. The carriage 5 is made in the form of a horseshoe-shaped frame 7 with p to. m oppositely arranged rolls 8 9 and the spacing of a reversing electric motor m 10 and a gearbox. /, designed to drive the rolls 8. The pressing rolls 9 are mounted on the carriage 5 in the sliders 12, which can be moved by a screw 13 and tightened by means of springs 14. The pressure rolls 9 are made replaceable in case of repair of the shells of various thicknesses and diameters, and the drive rollers 8 are mounted on the shaft with the possibility of their mutual movement and fixation. The drive rolls 5, located vertically, are kinematically connected to each other. In case of insufficient adhesion of the rolls 8 a 9 with perevaltsovymy edges m.i cloth / 5, an additional reversing drive 16, for example, a winch, whose electric motor si; nhr-onizirovan with the electric motor 10. The drive 16 is connected to the carriage 5 through blocks 17 by cable Js. On the other hand, the carriage 5 through the blocks 19 is connected by a cable 20 to the counterweight 6. The device operates as follows.

The carriage 5 is threaded so that the edge of the panel 15 is located between the rollers 5 and P. The guides are installed / into the shoes 3, which are fixed to the backing plate 2. In the upper part, the guides / are connected by a cross member 4. The systems are connected to the carriage 5, to which the cable 20 is also connected. Going to the counterweight 6. The screws and 13 rollers 9 are burned to the edge of the panel 15 and the reversing motor 10 is turned on.

When the rollers 8 rotate, due to the frictional forces between the rollers 8.9 and the edge of the cloth 15, the carriage 5 rises or lowers, turning the edge of the cloth to the desired radius. The reciprocating movement of the carriage 5 along the edge of the panel 15 occurs due to switching of the electric motor 10, on npHiMep, with the help of limit switches.

In order to achieve the required curvature of the edges of the cloth, the screws 13 are periodically pod-1 20

75 is wound through the spring 14. To prevent the carriage 5 from stopping, in case of insufficient adhesion of the rolls 5 and 9 to the panel or the presence of significant obstacles on the path of the carriage 5, a cable system with an additional drive 16 operating synchronously with BASIN1NY1M elec- like a drive 10. Drive 16 in all other cases, runs idle.

Thus, due to the movement of the rolls 5 and 5 and their pressure on the edges of the cloth, carried out under the action of screws 13 acting through the spring 14, the edges are corrected to the desired radius. In addition, this device provides a straightening, as the rolls and P are installed in the carriage in rows vertically.

After reaching the design curvature of the end sections of the shell, they are closed by known methods. In the event of a change in the radius of the mounted shells, the gland rolls 9 are replaced and the drive rolls 8 are retooled. The device is dismantled in reverse order.
