SU605675A1 - Device for conveying ingot in metal continuous caster - Google Patents

Description

The hydraulic cylinder is provided with an additional porn, into the stock of which a check is inserted, placed between the upper and lower CTyneHi stops, with the additional piston located coaxially with the main piston

This makes it possible to achieve a uniform distribution of the loads on the rollers and their bearings, which is important when transporting the seed. In addition, the rollers are evenly pressed as the circumferential force that occurs at the point of contact of the roller with the ingot (seed) occurs through the axes of the hinges, without creating a tipping moment at the traverse.

FIG. 1 shows the proposed device, side view; in fig. 2 is a view A of FIG. 1 in FIG. 3 - section bb FIG. one; in fig. 4 hydraulic cylinder; in fig. 5 - sweep stops.

Hydraulic cylinders 2 with rods and lower rollers 3 are mounted on frame1. Traverse 4 with upper rollers 5 mounted on it is hinged to rods of hydraulic cylinders 2 by means of mutually perpendicular axes 6 and 7 lying in the plane of lower forming rollers 5. In general The housing 8 of the hydraulic cylinder 2 (FIG. 4) is fitted with two axles 9 and 10, which divide it into three cavities b, c and g. A cross bar is attached to the rod 11 of the upper piston, and a transverse check 13 is installed on the rod 12 of the lower piston which are stepped stops 14 and 15.

The device works as follows.

The adjustment of the stand to the external section (i.e., adjustment of the solution between the rollers 3 and 5) is carried out by turning the stops 14 and 15 to the desired position. At the same time, the position of the lower piston 10 changes, because the check 13 in its rod with a gap of 2-30 mm is between the respective steps of the stops (Fig. 5).

When skipping seed, having a thickness of less than the thickness of the ingot (at 10-15 mm), the oil is fed into the cavity b. In this case, the scraper 11. -but is pressed by pressing the rollers 5 to the seed.

When an ingot is skipped, oil in the cavity g, b is additionally supplied. At the same time, the piston is raised to the stroke .4 due to

excess force on the etxi side over effort on the part of aepxHeix) piston; the check 13 is pressed against the upper abutment 14, the solution of the rollers / increases and becomes equal to the thickness of the ingot.

To raise the upper rollers to the maximum stroke, the oil is additionally supplied to the middle cavity (i.e., all three cavities b, c, d are under pressure). The upper piston 9 together with the rollers 5 in this case rises to the extreme upper position. To pass to the lower rollers 3, the yoke 4 together with the rollers 5 may be rotated 90 relative to one id of the axes 7, for which it is only necessary to remove the axis 6.
