Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to the overall arrangement of a planetary inclined roll rolling facility.

(Prior Art) A planetary inclined roll rolling mill has a configuration in which three or more conical rolls perform rolling work while rotating and revolving around a rolled material having a circular cross section or a nearly polygonal cross section. This type of planetary inclined roll rolling mill is a one-pass high-reduction mill, and must be equipped with a crop cut shear device behind it for cutting the leading and trailing ends and for cutting the rolled material in an emergency.

Furthermore, in the planetary inclined roll rolling mill 1, it is necessary to arrange a roll changing device for changing the rolls as close as possible to the rolling mill main body, but this roll changing device 4' is not used during the rolling operation. Since it is not necessary, it is made so that it can be moved to the outside of the rolling line X, and a trough 21 for guiding the rolled material can be installed on the rolling line X. In addition, the roll exchange device 4' generally includes mechanisms 4a and 4b for gripping and exchanging old and new rolls.
were arranged back to back, and the rolls were exchanged by rotating the main body of the exchanger half a turn (see Figure 6).

By the way, as shown in FIG. 6, the conventional planetary inclined roll rolling equipment avoids interference between the crop cut shear device 3 and the roll changing device 4', and allows the roll changing device 4' to operate without any trouble when changing the rolls. In order to enable rotation, it was necessary to provide a distance of 1 minute between the planetary inclined roll rolling mill 1 and the shear device 3.

(Problems to be solved by the invention) Conventional planetary type inclined roll rolling equipment requires a large space between its rolling mill and shear device, so the rolling mill itself has a large space compared to other rolling mills with the same rolling capacity. Despite being extremely compact,
The space occupied by the equipment as a whole could not be reduced much.

This idea was made in view of the above points, and its main purpose is to significantly reduce the space occupied by the entire planetary inclined roll rolling equipment and make it more compact.

(Means for Solving the Problems) This invention for achieving the above object is a planetary inclined roll rolling equipment consisting of a planetary inclined roll rolling machine, a roll exchange device, and a crop cut shear device. A rail track is laid perpendicular to the rolling line at the rear of the rolling mill, and the roll changing device and crop cut shear device are placed on the rail track so that they can run freely, and one of the devices is placed on the rolling line. The gist of this invention is that it can be selectively placed in the area and fixed via a lashing mechanism.

(Function) The planetary inclined roll rolling equipment of this invention selectively moves its shear device and roll changing device between their standby positions and the rolling line X, thereby performing rolling work or roll changing work. It is something to do.

(Example) Hereinafter, an example of this invention will be described based on the drawings.

Fig. 1 is an overall plan view of the planetary inclined roll rolling equipment, Fig. 2 is a view taken along the line A-A in Fig. 1, Fig. 3 is a view taken along the line B-B in Fig. 1, and Fig. 4. is C- in Figure 1.
A view taken along the line C and FIG. 5 are enlarged front views showing the securing mechanism of the truck.

In the figure, 1 is a planetary inclined roll rolling mill;
A pair of rail tracks 2 are laid orthogonally to the rolling line X at the rear of the rolling mill 1. Reference numeral 3 designates a crop cut shear device, and 4 designates a roll change device. The shear device 3 and the roll change device 4 are fixedly mounted on carts 5 and 6, respectively, which are movable along the track 2. Further, each of the carts 5 and 6 is equipped with a motor or a hydraulic cylinder (not shown) as a drive device, and the shear device 3 and roll change device 4
can be selectively moved between their standby positions and the rolling line X. In addition, the shear device 3 and the roll exchange device 4
As a means for stopping the rollers at their standby positions or at the rolling line X position, for example, there is a limit switch.

By the way, the roll exchange device 4 has a structure in which the old roll exchanger 4a and the new roll exchanger 4b are arranged in parallel in the longitudinal direction of the track 2, so that the length in the longitudinal direction is shortened, and the The old and new rolls can be exchanged by moving them laterally along the track 2.

Reference numeral 7 denotes a lashing mechanism for reliably fixing the carts 5 and 6 at fixed positions, and this lashing mechanism 7 is provided at the rolling line X position and at the standby position of the shear device 3 and roll change device 4. The structure of the lashing mechanism 7 is such that an engagement piece 8 that can engage with an engagement hole (not shown) provided on each of the carts 5 and 6 is rotatably pivoted to both sides within the track 2. The engaging piece 8 is rotated by the cylinder 9. Although the securing mechanism 7 is provided on the rail track pedestal in this embodiment, it can also be provided on each of the carts of the shear device 3 and the roll exchange device 4, and is not limited to this embodiment.

11 is a horizontal roll rolling mill; 12 is a vertical roll rolling mill; these roll mills 11 and 12 are connected to the rolling line
They are sequentially and alternately installed from positions that do not interfere with the shear device 3 and the roll changing device 4 along the line.

Next, to explain how the rolling equipment of the above embodiment is used, the roll changing device 4 is used during rolling work.
is fixed at the standby position via the lashing mechanism 7, and the shear device 3 is moved to the rolling line X position and fixed via the lashing mechanism 7. In this state, the rolled material is sent out along the rolling line X from the planetary inclined roll rolling mill 1 side and a rolling operation is performed. When replacing the rolls, the shear device 3 is moved to the standby position and fixed via the lashing mechanism 7, and the roll changing device 4 is moved to the rolling line X position and fixed via the lashing mechanism 7. This is used to replace rolls.

(Effects) Since the planetary inclined roll rolling equipment of this invention has the above-described configuration, it has the following effects.

(1) The rolling equipment as a single unit consisting of a planetary inclined roll rolling mill, a crop cut shear device, and a roll changing device is more compact than conventional equipment, and the space it occupies can be significantly reduced.

(2) When modifying existing rolling equipment and installing a planetary inclined roll rolling mill in place of another model of rolling mill, it was previously necessary to remove four stands of rolling mills. Therefore, according to the rolling equipment of the present invention, it is only necessary to remove two rolling stands, so a large number of existing subsequent rolling mills can be utilized, which improves the rolling work capacity and provides more leeway for work. , an increase in production can be expected. In addition, even when production is carried out irregularly using rolling mills that were not removed during remodeling work, as mentioned above, the number of existing rolling mills removed is small.
Since it is possible to avoid making the entry side billet smaller than necessary, the necessary billet can be easily obtained without modifying the conventional billet supply equipment, making it possible to continue production. You can expect it. Furthermore, it can be installed within a limited space, and the cost of modifying the foundation and removing existing equipment is reduced.

(3) When installing new rolling equipment, the overall length of the rolling line can be shortened and the size of the building can be reduced at the same time, reducing equipment costs.
