Description

Cooling bed. Addition to patent 436816. In the main patent on a cooling bed for rolling mills, the cross conveyor was built as a novelty in such a way that the Removal of the rolling bars on the cooling bed according to the various profile dimensions and is large at the beginning and small at the end according to the different temperature zones. It is achieved that the incoming hot rolling rods in the first part of the Cooling bed are far apart for good and quick cooling, while with increasing cooling the rod distance decreases more and more to the end of the bed to go down to the width of the bar. So there is a constantly changing occupancy density, which uses the cooling bed most economically with the smallest width. Can continue for small profiles, which are known to cool down more quickly than large profiles, cross conveying in the first part with a large stroke and in the rear part with an evenly smaller stroke to be worked. Success is achieved with the invention of the main patent the special training of the lower rake and the adjustable mutual Altitude from the lower movable to the upper, fixed during operation Computing system.

With this type of design, the cross conveying was carried out through the lower, caused by a rake swinging a curve, the rolling rods move away from it upper fixed rake adjustable in height and again hang up.

The constantly changing density of movement can now according to the new Embodiment achieved in that we clear that instead of oscillating in a curve Rake for cross conveying one of the known, uniformly moving conveying means (Tightly stretched endless rope, endless chain or one moving back and forth Rail) is used, from which the rolling rods are continuously lifted and put back on are interrupted by the lifting of the rolling rods, the transverse conveyance and by placing the same, their transverse conveyance is initiated again. Ever according to the time ratio between the speed of the conveyor and the support of the rolling bars on the conveyor, the bar distance becomes larger or smaller and thus achieved the variable occupancy density.

The drawing shows: Fig. I Cross-section of the cooling bed with Adjustment to constant, even occupancy density by adjusting the lifting zone the rake that can be opened and closed with upper edges parallel to the upper edge of the conveyor, Fig. A Longitudinal section of the cooling bed according to Fig. I, Fig. 3 Partial section of an up and down foldable rake according to fig. i and z to explain the stroke zone adjustment, set for maximum cross conveying, Fig. q. Partial section of an open and foldable Rake according to Fig. I and z to explain the stroke zone adjustment, set for smallest cross conveyance, Fig. 5 Cross section of the cooling bed with setting to steady variable occupancy density by adjusting the lifting zone of the foldable and openable Rake with upper edges inclined to the upper edge of the conveyor, Fig. 6 longitudinal section of the cooling bed according to Fig. 5, Fig. 7 Partial section of a rake that can be opened and closed according to Fig. 5 and 6 to explain the stroke zone adjustment, set for the largest Cross conveying, Fig. 8 Partial section of a rake that can be opened and closed according to Fig. 5 and 6 to explain the adjustment of the stroke zone, set for the smallest transverse conveyance.

The rolling rod a is deposited by a known lifting device b .from the channel of the roll-up aisle.sc in dd onto the upper edges of the rake / . At the distance g from the upper edge e of the rake f, a conveyor k moves sideways in the direction of the arrow. As long as the rolling rod a lies on the higher upper edge e of the rake f, it remains at rest. If the upper edge of the rake / is moved below the upper edge of the conveyor device lt , then the rolling rod a is placed on the conveyor device h, and the transverse movement of the rod a begins. The cross conveyor remains in operation until the roller bar a is lifted by the upper edge e of the rake / from the upper edge i of the conveyor lt .

The upper edge e of the rake f is moved by rotating the rake f by the angle a and by means of a linkage k in conjunction with a crank. The distance g between the upper edge t of the rake f and the upper edge i of the conveying means can be changed as required by means of a handwheel nt.

The deflection angle a is determined by the upper edge i of the conveyor into an angle: cl i3 and Y broken down, of which angle 3 is above the upper edge i, the angle Y is below the upper edge i of the conveyor device.

As can be seen from Figs. 3 and ¢, if the distance g is changed, the angles 3 and y are also changed. Since the sum of the angles 3 and Y is equal to the a, changing the distance g must change the time with which the roller bar a remains in contact with the upper edge i of the conveyor h, and thus also the conveyor path. It clearly emerges from Figs. 3 and 4 that the transverse movement is greatest at the smallest angle 3 and the transverse movement is smallest at the largest angle 3, so that the conveying paths are in inverse proportion to the angles 3.

In Figs. I to q. the distance g is now assumed to be uniform over the width of the cooling bed, i.e. the upper cart e of the rake / parallel to the upper edge i of the conveyor device lt , whereby a steadily uniform occupancy density occurs over the cooling bed.

If the distance g, as shown in Figs. 5 to 8, in the front Part of the cooling bed chosen differently than in the rear part of the same, i.e. the upper edge e of the rake / arranged inclined to the upper edge i of the means of transport, so occurs a constantly changing occupancy density across the entire width of the cooling bed.

: The difference in the angles in the anterior can be seen in Figs. 7 and 8 and rear part. Since, as stated above, the conveying routes are reversed Relation to the angles 3, so. occurs a constantly changing »occupancy: density a.

Instead of the parallel or evenly inclined arrangement the upper edge of the rake e to the upper edge of the conveying means i can also be curved Arrangement of the rake. top edge e can be selected. As a result, the front part of the cooling bed the continuously variable, in the rear part of the same the uniform occupancy density he aims.

Furthermore, instead of the regular occupancy density, an irregular Bending density can be achieved with the devices described in that after taking up a certain number of roll bars, the distance g is adjusted by the handwheel m and so that the rod distance can be changed as required.

The distance g is set in the exemplary embodiment from FIG Hand, but the same can also be done mechanically using known devices.

The endless support chain provided as a conveyor in the exemplary embodiment can also be done with equal success by swinging rulers back and forth or by swinging bodies of revolution, also looking back and forth through screw threads be replaced. When using this funding, the rolling bars to be moved during the movement of the rails or rotating bodies in the conveying direction this placed on top of it, lifted from it in the opposite sense when moving, whereby the desired transverse movement comes about.
