Description

APPARATUS FOR HIGH PRODUCTIVITY ROLLING, PARTICULARLY FOR MILLING SECTION BARS OR RODS
The present invention relates to an apparatus for high productivity rolling, particularly for rolling section bars or rods.
More precisely, the invention refers to a rolling plant for the production of rolled sections, such as section bars or rods, able to simultaneously perform multiple laminations, so that each group of rolling lines of which the plant is provided can work a material, regardless of the working of another material by another group of rolling lines.
Currently rolling mills as that one shown in figure 1 B are known.
In order to reduce production costs, the material to be rolled 101 is firstly inserted into an intermediate train 102, in a shape having a diameter larger than those ones of the finished product.
Subsequently the material is divided into two bars 101 A and 101 B of the equal section, each of which is carried by a respective finishing train, along a respective line 200Dx or 200Sx, passing through a series of pairs of successive rollers, each of which constitutes a rolling "stand".
The process usually includes a plurality of stages, in each of which the rollers of the pair of each stand are positioned at a mutual distance corresponding to the gauge requirements and rotate at a synchronous speed with the cylinders of the previous or successive stand.
If the distances of the rollers are not correct or speeds are not synchronous between the stands, additional friction forces between roll and material, or tensions between the stands generate, dissipating energy uselessly.
In the two lines 200Dx and 200Sx, the stands are arranged in a sequence such that to shape the material into the desired final shape, always moving in one direction.
In a rolling mill for round or square profiles, for example, the stands are usually arranged alternating pairs of horizontal rollers with pairs of vertical rolls, until the material reaches the aforesaid desired shape. The two lines 200Dx and 200Sx of the rolling stands are separated from each other and each of them is fed by a respective motor.
Moreover, changes related to the shape and dimensions of the material to be shaped take place simply by varying the diameter of the rollers or the distance between them.
Finally, the two finishing trains on which the bars 101 A and 101 B are transported converge towards a single area of cooling and packaging of the finished product.
A drawback of such a rolling mill is that it is little flexible in managing the lamination. The group of stands is driven by one motor. Shape or speed change on a stand involves a change on all the stands of the group in order to keep synchrony among them. If the lamination of the product requires a lower number of stands, the remaining stands operated by the same motor must in any case rotate, with considerable waste of energy.
At the current state of the art the need to provide the use of a rolling apparatus able to guarantee flexibility about the working shapes and dimensions remains.
In particular, it is evident the need to provide a rolling apparatus allows independent adjustment of each pair of rollers compared to other pairs of rollers arranged in said apparatus.
In addition, a second drawback of such a rolling apparatus is that it is little efficient in the production and management of spaces. Indeed, in order to be able to roll more wires simultaneously, it is necessary to arrange more finishing trains.
It is clear from the above that it is necessary to get a rolling apparatus which implies a high production efficiency.
Therefore, the purpose of the present invention is to overcome the drawbacks of the known technique, by providing a rolling apparatus which results in a production efficiency higher than that one of the known rolling apparatuses.
In particular, purpose of the present invention is to create an apparatus for simultaneously rolling two or more wires which allows an adjustment of the profile of a rolling line, without such an adjustment affects the profiles defined for other rolling lines.
Within such a purpose, task of the present invention is to provide a rolling apparatus that allows activation of individual stands through independent motors.
Yet another purpose of the present invention is to provide a rolling apparatus which avoids electricity waste for its operation, by using multiple motors of dimensions smaller than those ones used in known apparatuses, avoiding waste of energy due to the rotation of stands not necessary to the process.
Further purpose of the invention is to provide a rolling apparatus which allows a production speed higher than that one allowed by the known technique apparatuses.
These and other purposes are achieved by a rolling apparatus, as the appended claim 1 , as hereinafter referred for the sake of brevity of exposure.
Further technical features of detail of the apparatus according to the invention are indicated in the corresponding dependent claims.
Advantageously, each stand of the rolling apparatus is driven by a respective motor. In this way it is possible to use a pair of cylinders having different diameters. The single motor, indeed, is able to modulate the rotation speed of these cylinders in order to compensate the diameter difference.
A second advantage is given by the fact that the cost of the rolling apparatus according to the invention is lower than those one of the prior art, since it provides the installation of a single line of finishing train instead of the two lines of finishing lines provided in the rolling apparatus of known type.
Consequently, a further advantage is related to saving in infrastructure, since the length of the production line, as a whole, is lower than that one of the production lines of the known rolling apparatuses.
Still another advantage is due to the fact that only a lamination stand is used at each stage of the rolling process, through which two or more wires simultaneously pass, in autonomous manner as far as the distance between the cylinders is concerned.
Moreover, it is possible to act independently on the single stand, changing the distance between the cylinders in relation to a wire, without affecting the other wires.
These features favour:
- time saving in the adjustments Of the distance between the rollers,
- flexibility, since it is possible to intervene on the single stand and at the same time on the single step,
- energy saving, with the possibility to turn off the stands not involved in the process. This therefore implies a significant reduction in production costs.
Said purposes and advantages will appear to a greater extent from the description that follows, related to a preferred embodiment of the rolling apparatus according to the invention, given by indicative and illustrative, but not limited, way with the help of the attached tables in which:
- figure 1A is a functional scheme of the rolling apparatus according to the invention;
- figure 1 B is a functional scheme of a known rolling apparatus;
- figure 2 shows a lamination stand of the rolling apparatus according to the invention;
- figure 3 shows a variant of the lamination stand of the rolling apparatus;
- figure 4A shows in detail the lamination stand of figure 2;
- figure 4B shows a particular of figure 4A;
- figure 4C shows in detail the lamination stand of figure 3;
- figure 5 shows a side section of the lamination stand of figure 3;
- figure 6 shows the lamination stand of figure 3, in a position with a changed distance between a pair of cylinders.
With reference to figure 1A, the rolling apparatus according to the invention, indicated with reference number 1 , provides an intermediate train 2, in line with a finishing train 3, comprising a plurality of stands 4, placed in sequence, in horizontal or vertical position, each of which is driven by a respective motor 5, in an amount that can vary from four to ten or more.
With reference to figure 2, the stands 4 of the finishing train 3 include two rolling cylinders 6, each of which is provided with two respective channels 7Dx, 7Sx.
These channels 7Dx, 7Sx are arranged respectively at one of the ends of said cylinders.
Figure 3 shows the embodiment of the stand 4 of the finishing train 3.
Stands 4 of the finishing train 3 include two rolling cylinders 6, each of which is provided with two respective pairs of channels 7Dx, 7Sx, arranged at the ends of said cylinders.
In both cases shown in figures 2 and 3, the channels 7Dx, 7Sx define the rolling profiles of the product to be processed, along two/four separated rolling lines 8Dx, 8Sx (perpendicular to the plane of the drawing).
The two cylinders 6 are bound each other at the two ends.
Every cylinder 6 has a first end connected with a first gauge 9Dx, through a spherical bearing 10Dx, and a second end connected with a second gauge 9Sx, through a spherical bearing 10Sx.
Every gauge 9Dx, 9Sx, by rotating along the trajectory T, defines the distance ADx, ASx between the cylinders 6 near the respective channels 7Dx, 7Sx.
By means of a manual or driven by a remote control unit adjustment device, the first gauge 9DX changes the distance ADx between the cylinders 6, at a respective first channel 7Dx.
At the same time, the opposite second gauge 9Sx, connected through the spherical bearings 10Sx with the respective ends of the two cylinders 6, stands still, and allows the main axes of the cylinder to rotate in order to follow the movement of the opposite ends adjusted by the respective first distance adjusting group 9Dx.
By observing now figures 4A, 4B and 6, the axes of the cylinder 6 rotate according to an angle a, useful to make such a change towards the distance ADx at the first channels 7Dx, depending on the distance D between the first channel 7Dx and the opposite second channel 7Sx.
In particular, the rolling lines 8Dx, 8Sx are arranged at a distance D, such that the adjustment of the distance ASx performed on a first rolling line 8Sx does not affect the distance ADx on the second rolling line 8Dx.
Of course, the distance D is defined from time to time on the basis of the diameter of the rolling channels 7Sx, 7Dx, and the desired change values on a first rolling line 8Sx, as well as the maximum allowed change values on a second rolling line 8Dx.
Even more specifically, in the embodiment shown in figures 3A and 3B, change V of the rolling distance on the rolling line 8Sx causes a change of the rolling distance on the rolling line 8Dx not greater than V/5.
For example, if on the left rolling line 8Sx a change V = 1 mm takes place, on the right rolling line 8Dx a maximum change equal to 0.2 mm takes place.
Advantageously, in this way, it is possible to act differently on a first rolling line 8Dx with respect to a second rolling line 8Sx, even if they belong to the same lamination stand 4.
With reference to the embodiment of the lamination stand 4, shown in figures 3, 4C, 5 and 6, each cylinder 6 presents four respective channels 7Sx, 7Dx, which are arranged tow by two at the ends of each of said cylinders 6, and define the rolling profiles of the product to be processed, along four rolling lines 8Dx, 8Sx, separated from each other.
Similarly to the main embodiment shown in figures 4A and 4B, the right rolling lines 8Dx are placed- at a distance D from the left rolling lines 8Sx, such that the adjustment of the distance ASx performed on a first pair of rolling lines 8Sx does not affect the opposite pair of rolling lines 8Dx.
In a further embodiment of the lamination stand 4, not shown, each cylinder 6 presents a plurality of respective channels, divided into two groups. Each group is placed at one end of the pair of cylinders and defines the rolling profiles of the product to be worked, along a plurality of rolling lines.
This advantageously allows for multiple laminations simultaneously, being able to manage the shape and sizes of a first group of rolling lines independently from a second group of lines rolling.
In addition, it is possible to increase the number of rolling lines compared to the prior art, while keeping minimum overall dimensions, lower than that one of the known plants.
Finally, while providing a motor for each stand, the used motors drive only one pair of cylinders, therefore they have sizes and power consumption lower than the motors used in the known plants.
Independence in managing individual stands allows to adjust the distance between the single pairs of cylinders without interrupting the process.
Therefore, the features of the apparatus for high productivity rolling, particularly for milling bars and rods, which is the object of the present invention, as well as the advantages, are clear from the description given.
Finally, although the invention has been described by illustrative, but not limited, way, according to a preferred embodiment thereof, it has to be understood that changes and/or modifications could be made by person skilled in the art without for this reason going out of the related scope of protection, as defined by the appended claims.
